CXD汽水取样装置操作及常见故障的排除

CXD汽水取样装置操作及常见故障的排除

CXD汽水取样装置操作及常见故障的排除(音画版)一、高温架(画面为高温架全景,字幕推出:《CXD型汽水取样装置》高温架操作;字幕消失,全景定格)画外音;在高温架的样水投入之前,操作人员应(1)、先检查高温架上的所有阀门是否关闭。

确认关闭后(2)、在查看所有降温降压器的冷却水出、入口阀门是否开启,确认开启后,投入高温架的冷却水系统。

(3)、冷却水的工作压力和工作压差是否符合高温架的运行条件,这一点在手工取样盘上的冷却水出、入口压力表中可查得。

(画面切换到手工取样盘上,近景拍出、入口压力表指针读数)方法是;冷却水工作压力应为;入口压力表>0.2Mpa。

冷却水工作压差=入口压力-出口压力,标准工作压差为≥0.15Mpa。

(4)、查看手工取样盘上的流量控制阀是否关闭。

(画面转向流量控制阀)以上各项确认后,方可按步聚操作高温架。

(画面切回高温架)(画面合着画外音而移动)1)先慢慢开启某一样点水的一次阀,直到全部打开后,2)再开启这一样点的排污阀,开启的速度要加快,达到最大开度。

如果是启炉排污,排污的时间略长一些,将管路中存留的样水排尽,新的样水到来,快速关闭排污阀,然后再快速开启。

阀门打开的时间在十秒之内,反复几次即可。

确认排污结束,将排污阀快速关闭,关严。

(3)将二次阀慢慢开启,达到满开度,样水就会流出高温架。

高温架操作结束。

(高温架全景定格)二、手工取样盘(手工取样盘全景,画面随着画外音移动)画外音:当高温架全部投入运行或某一点样水投入运行后,在手工取样盘上对应点的手工取样阀和流量计应全部打开,防止样水冲击和低压管路的损坏,此阀门和流量计可永不关闭。

然后缓慢开启流量控制阀,让样水流出。

样水的流量取决于化学仪表的多少,在流量计上40~90为好,也就是说650~1500mmI/in。

电接点压力表入口处,接有冷却水失压保护装置。

当冷却水突然间断流,电接点压力表将接通保护,关闭高温架上的所有水样,防止设备的损坏和保证运行人员的安全。

GRAND POWERWater and Steam Integrated Sampling Unit INSTRUCTIONModel: CXDJILIN CITY GRAND POWER EQUIPMENT CO., LTD.I. SummaryThis unit is adapted to pre-treatment the sample of water and steam for chemical analysis of thermo-equipment, manual sampling, on-line quality analysis of water and steam, computer supervising of the checked parameters.This unit composes of three basic sections: CXD series Sampling Unit of Chemical analysis, which functions in pre-treatment, manual sampling, providing eligible sample for on-line chemical analysis; Analysis instrument screen, on which installs on-line chemical analysis instrument and record displayer etc.; Computer control system, which functions in data collection, treatment, display, reports print, supervising, and epigynous computer control communication etc.Clients can select part of the unit or select all according to demand.II. CXD series sampling unit of chemical analysis1. Technical characteristicUsing a total complete new techno-route, this unit acquires outstanding benefit that other sampling units cannot match, either domestic or overseas. In detail, the characteristics are as below:(1) The sampling unit adopts high-efficiency temperature-pressure reductor (with patent) for fluid of high-temperature and high-pressure. When fluid of high-temperature and high-pressure (such as water, steam etc.), flows along this unit, the temperature and pressure will be reduced, that is the unit works with double functions, one is as the cooler of traditional sampling unit, the other is as the reductor.(2) The sampling unit is not set with pressure-only reductor, which puts an end to the traditional disadvantage caused by reductor block resulted in too much maintenance.(3) The sample flows along the high-efficiency temperature-pressure reductor in a status of deep puffing, with high heat-exchange efficiency. Under the same condition, the usage of the cooling water is only 1/2 ~2/3 that of the existing cooler.(4) The sample flows along the pipes of the high-efficiency temperature-pressure reductor with speediness that helps the wall of pipes self-clean.(5) The sampling unit adopts a new-type filter, pole-style filter (with patent), barring mechanical impurity granule with diameter over 1.4mm without changing the composition of the water sample basically. Pole-style filter can self-clean for the large flux of the sample, block-proof, if need be, the exhaust drainage valve can be started to clean the filter. The pole-style filter is solid and durable, exempt from maintenance.(6) The sampling unit has a compact structure occupying little space, for example, ten-point of sampling unit is 2.5m long, 0.65m wide, and 1.6m high, every point of sampling added, only 0.2m longer needed, without changing of width and height, therefore, the occupying area is only 3/5 of the current sampling unit.2. Working conditions(1)Temperature of the environment:5~40℃(2)Power supply: 230V±10%,50Hz, 2KV A(3)Cooling water:A: Temperature: <35℃B: In/Out Pressure difference for cooling water in the temperature-pressure reductor: >0.2MPa C: Flux: subject to the number and the temperature of sampling points, fifteen points of sampling designed according to 30T/hD: The cooling water of the temperature-pressure reductor adopts de-salted water, without rot, dirt or pollute.3. Main technical index(1) Under the condition of the temperature not higher than 560℃and the pressure not bigger than 35Mpa, the temperature of the treated water is about that of the cooling water plus 5℃(±1℃), the pressure is smaller than 0.3Mpa.(2) The flux of water sample: ≥1500ml/min(3) Temperature of the outlet water can be set an alarming rating by the round detector by which the max absolute error measured should not be higher/lower than 1℃. Any exceeding of the alarm value will cause automatic alarming. The normal alarm is set at 40~50℃.(4) Pressure safety valve of the outlet water sample is set at 0.6~2.8Mpa, adjustable. Inlet of cooling water has pressure-overloading alarm, with lowest setting at 0.2MPa and highest setting at 0.8MPa.4. Formal dimensionsSeventeen-points sampling unit is 3.6m long, 0.65m wide and 1.60m high.5. Debugging procedure5.1. Preparation before operation5.1.1. According to the system diagram, be familiar with the positions and functions of all sections for the sampling unit.5.1.2. Regulate the pressure limits on the contacts of cooling water, and check the alarm system if normal.(1) Set the pressure meter on the contacts of the inlet cooling water pipe with a limit at 0.2MPa~0.8MPa.(2) Set the pressure meter on the contacts of the outlet cooling water pipe with a limit at 0MPa, and the pressure difference to the inlet not lower than 0.2MPa5.1.3. Power on the round detector, set the sampling cycle and alarm values according to Instruction settings.(1) Max. value of alarm is set at 40~45℃(2) Min. value of alarm is set at 0℃5.1.4. Check the nodes, airproof parts, fastening parts of the sampling unit if loosed, check the valves if closed.5.2. Pour in cooling water5.2.1. Open all in/out ball-valves at all points of sampling for cooling water5.2.2. Open the valves for in/out cooling water pipes. Pressure difference between inlet and outlet of cooling water pipes should not be lower than 0.2Mpa, as normal.5.2.3. Check the alarm(1) Regulate the inlet pressure on the contacts of cooling water at maximum (actual pressure of the cooling water, if alarmed, regard the alarm as normal. Then recover the pressure 0.8MPa.(2) Regulate the inlet pressure on the contacts of cooling water at minimum (actual pressure of the cooling water, if alarmed, regard the alarm as normal. Then recover the pressure 0.2MPa.(3) After finishes the alarm debugging, regulate the pressure difference between inlet and outlet at a stable status of 0.2MPa.5.3. Operation of high-temperature and high-pressure systemOnly if the cooling water works in normal condition, the high-temperature and high-pressure system can be operated.5.3.1. Manual sampling valve and the flowmeter knob are all opened5.3.2. Close first inlet and second inlet valves of sampling water, drainage valve and flow control valve.5.3.3. Slowly open the first inlet valve of the sampling unit, watch the connections of filter, the second inlet valve, contamination-drain valve to check if leaking, if leaks, fasten with special spanner (Be careful, work with gloves against scald).5.3.4. After the connections of the first inlet valve, contamination-drain valve and filter are confirmed no leakage, slowly open the contamination-drain valve to drain away the water in the pipe, with the temperature of water heighten to a stable point, fully open the contamination-drain valve then close immediately, repeat the operation of on and off for about three times, then close the valve.5.3.5. Slowly open the second inlet valve, watch the system of high-temperature and high pressure if leaking, if leaks, close the first inlet valve, repair the leakage, then open the second inlet valve. 5.3.6. Slowly open flux-control valve, watch the floater of the flowmeter rising, if the water sample flows smoothly, that will be considered normal.5.3.7. Regulate the flux-limit valve of manual sampling, make the flowmeter displaying a flux about 500ml/min, and regulate the instrument valve to let the instrument start working.5.4. Temperature overloading protection test for the electromagnetic valve5.4.1. Sizing down the inlet flux of the cooling water (smaller the opening of the valve), watch the display of the temperature round detector, when exceeds the alarm temperature, alarms, and at the same time the electromagnetic valve starts working to cut off the flow of the sample water, that certifies the normality of temperature overloading protection, then sizing up the inlet flux of cooling water (bigger the opening of the valve), recover the normal working status.5.4.2. Close the first valve, open the contamination-drain valve, the pressure of the water-flow system is reduced, open the water circuit which has been cut off by the replacement of the electromagnetic valve, then close the contamination-drain valve, open the first valve, recover the normal working status. When the decontamination system pressured, the above-mentioned operation could not open the electromagnetic valve. In case of that, close the flow-control valve on the manual sampling board, then go to the rear of the manual sampling board, loose the outlet running tie-in of the flow-control valve, discharging the air as well as the pressure, so then the electromagnetic valve will automatically open.5.5. Cooling water pressure reducing alarmDuring the operation, when the inlet pressure of cooling water lower than 0.2MPa, alarms, at the same time, the electromagnetic valve closes all its actions, cuts off the water circuit, when things happened like that, find the reasons then repair it(reasons, see the descriptions in the malfunction analysis column), the cooling water recovers the normal working status. If the electromagnetic valve does not action—not opened, do according to 5.4.2.5.6. Debugging of the safe valve5.6.1. The safe valve is set between the flux-control valve and the flowmeter, setting working pressure of 0.6MPa, acting pressure of 0.8MPa, when the flow circuit has overloading pressure, the safe valve automatically unloads. The safe valve is regulated well when leaving the factory, normally does not need regulating during the unit working. When it operates for a period of time or finds any malfunction, if need be, rechecks and regulates the safe valve as below:Connect pressure meters at the rear of the safe valve and between the connective pipes of the safe valve (range of 1MPa), close the water circuit to the instrument, regulate the manual sampling valve to raise the interior pressure of the sample water pipe to 0.6~0.8MPa. The safe valve starts to work, and be closed when the pressure lowers to 0.5~0.6MPa, then recover the normal working status. Otherwise, regulate the settings of the safe valve to the status above mentioned. Unload the pressure meter and install the safe valve.5.7. Operation StopFirst, close the first inlet valve of the sample water, then close the second inlet valve of the sample water and the contamination-drain valve, when the sample water stops flowing, close the inlet and outlet valve of cooling water, then close the power supply of the temperature detector.5.8. MaintenanceOpen the contamination-drain valve timely, according to 5.3.4. The period of contamination drain is subject to the purity of the sample water and the operational experience.〇Sampling point; Sampling point through ion exchange pole;side.Operating Rules for chemical analysis of CXD water and steam Sampling UnitI. PreparationBefore operates, check the valves of all points if they are closed, such as first high-pressure valve, second high-pressure valve, high-pressure contamination-drain valve and manual flux-regulate valve on the panel; check the screws if they are loosed, such as that of the high-pressure contacts on the unit (pipe joints of first/second class on the temperature and pressure reductor), cooling water piping, if need be, fasten the loosed.II. Cooling waterBefore operates, let the cooling water into operation with required condition. Requirements of the cooling water as below:1. Inlet temperature of cooling water <35℃;2. In/out pressure difference of cooling water should be not lower than 0.2MPa, (lower than 0.1MPa is definitely forbidden), calculated as inlet pressure – outlet pressure (read from the pressure meters of inlet and outlet)3. Flux of cooling water should reach the required amount. If In/out pressure difference of cooling water is eligible, the flux is satisfying.4. After the normal working of the unit, the cooling water should not be stopped to prevent accident of persons and equipment. In order to prevent accident, clients should set a spare power supply for the temperature round detector, if need be, contact the manufacturer for detail information.III. Temperature round detector and electromagnetic valveAs powers on, the temperature round detector shows temperatures of all points, alarms when pressure-loss, alarms when temperature overloading, electromagnetic valve working and some other functions.IV. OperationAfter finishes the above items, the unit could be started, according the procedure as blow:1. Open the manual sampling valve, floater flowmeter valve on the panel of manual sampling to prevent the result of pressure increased of low-pressure piping, or leakage, damage of flow meter. Above two valves can be often kept opened even if the boiler is stopped working.2. Open and close the high-pressure valves(first valve, second valve, contamination-drain valve) on the sampling unit, that must be fully open and fully close to prevent the fluid of high-temperature and high-pressure flooded and damaging the needle of the valve. That is important, please remember.3. When operates the unit, slowly open the first high-pressure valves at all points till they are fully opened, then open the contamination-drain valve (fully open), drain all contamination in the pipes, the detail draining time subject to:1) Contamination drainage when boiler starts: drainage away all the cooling water in the pipes, till the temperature of the pipes rises, then close the drain valve in a short time.2) Contamination drainage during operation: after the drain valve is open for five to ten seconds, then close it in a short time, if the sample water is dirty, repeat the above operation for some times, ordinarily once to three times.After finishes the contamination drainage, slowly open the second high-pressure valve, let the sample water flow along the filter to the temperature and pressure reductor, watch the high-pressure joints and pipes checking if leak. Normality confirmed, open all the second valves. That is the operation end of the high-pressure section.Note: the flux-regulate valve before the manual sampling panel is also a high-pressure valve( the front is high-pressure, the rear is to the low-pressure pipes). Prohibit working the first or second valve as sample water flux-regulate valves, otherwise, result in the high-pressure valve in the status of half-closed, that will destroy the high-pressure valve without working normally.V. InstrumentStart instruments with required quantity of sample water. First, open instrument valves that samplewater of all circuits flows through to the instruments, when the sample water to the instrument too much or too less, regulate the flux-limit valves set in the circuit of the manual sampling. The flux-limit valve regulates down, the sample water in the instrument will be increased, otherwise, reduced.VI. Safe guarantee system1. Temperature overloading alarm: there is temperature-overloading alarm set in the temperaturedetection, when the sample water at an exceeding temperature, the detector utters a buzz alarming, and at the same time commands the electromagnetic valve closed, sample water cut off to guarantee the security.2. Pressure-loss alarm: when the cooling water dammed by accident, the pressure meter at contactswill make pressure-loss alarm, and at the same time commands the electromagnetic valve closed, sample water cut off to guarantee the security.3. Low-pressure safety valve: for some reason (sample water of the instrument used stopped with theflux-limit valve opened), the pressure of pipes increased, when exceeds the security value of 0.7MPa, the low-pressure safety valve automatically opened, drains, till the pressure recovered, closed automatically.VII. Notice1. Pour in the cooling water at first, guarantee the pressure and pressure difference as required(Instruction).2. Manual sampling valve: the flowmeter should be opened or often be opened, to prevent any littledamage.3. The electromagnetic valve works in accordance with the commands of temperature detection and pressure meter of contacts, if the sampling point without sample water, close the first high-pressure valve at once, then open the contamination-drain valve, unload the pressure in the temperature and pressure reductor, then close the contamination-drain valve, start the electromagnetic valve automatically (not working) to prevent damage due to overworking and overheated, find the reasons, recover the normal working status of cooling water, then reset another time high-pressure valve, make the unit(sampling unit) work.EXCURSUS:1.The specifications of ion exchange pole: Ф51x4 mm H=800 mmV=1.161x10-3 m3=1.16 L2.Filling strong positive resin: Dool large pores positive acidic resin strong.GRAND POWER 光大电力GRAND POWER 光大电力Explore the cooperation and make friends all over the worldJilin Mengyou Tech •Grand Power Equipment Co., Ltd. reserves the right of amendment Address: Mengyou Technological Industry Park, Jilin High and New Technological Industrial Development ZoneP.C.:132013Tel. 86 432 4674552 Fax: 86 432 4683867 email:******************。
