Operation&Maintenance ManualGear Pump Type YCB Cangzhou Head Pump Co.,Ltd1.General1.1YCB series of circular arc gear pump is a new type external gear pump and of the latest construction,jointly developed by the Hydraulic Research Office of Mechanical Engineering Department,Shanghai Jiaotong Universitv,and Botou Gear Pump General Plant.The gears of pump have the teeth figure of the advanced arcs compounded with other curves,thus making it have good-working pared with the traditional Gear Pump2CY with involutes teeth,this pump has the characteristics of little pressure wave,low noise,high efficiency and long service life.It is a new type of energy-saving pump.1.2The circular arc gear pump is suitable for petrochemicals,ship-building industries and other industries to pump in different lubricating oil mediums,such as petroleum,heavy oil and industrial light oil,at a temperature below 70℃and with a viscosity5-1500cSt.But it is not suitable for pumping in oil with hard particles and the other fibred particles,nor is fit for high volatile but low flash point oil,such as gasoline,benzene medium liquid.1.3Safety valve is supplied with standard pump unless otherwise stated.1.4The pump is driven by the motor through the claw coupling,and they are fixed on a cast base plate or a welded from profile steel.1.5The circular arc gear pump can be installed horizontally or vertically or in other directions as required to meet different conditions.2.Model and standard technical data of gear pump2.1Model and standard technical data of pump2.1.1Motor power is chosen according to the shaft power,when the viscosity of oil is at30cSt.2.1.2The motor power should be raised along with the increase of the viscosity,the exhaust pressure or the exhaust pressure with safety valve.2.1.3Selection of the motor speed:Four-phase motor is for viscosity below500cSt;six-phase motor is for viscosity above500cSt.2.1.4The standard scope of viscosity:5-1500cSt.2.1.5Temperature below80℃2.1.6The direction of rotation is clockwise viewed from coupling end.(the pump-in entrance is on the left.And exhaust exit on the right)If the end users require to change the rotation,please indicate when ordering.2.2Model explanation YCB5—0.65capacity m3/h;0.6pressure MPa;B stands for“beng”which means PUMP in Chinese;C stands for“chi”which means GEAR in Chinese;Y stands for“yuan”which means circular arc in Chinese;3.working principle of gear pumpFig.1shows that a pair of gears that are engaged are installed inside the casing with two ends sealed by the front and back covers.Gears divide the inside of the casing into cavity A and cavity B which are not interlinking.When gears revolves as Fig.1indicates,cavity A’s volume is enlarged gradually because of the disconnection of the teeth,resulting in part vacuum,and oil in the tank flows through oil tubes into cavity A under the external atmosphere pressure.So cavity A is called as absorption cavity.The absorbed oil in the cavity A flows into cavity B in sealed space along the inside wall of casing when gears revolve.Oil between gear teeth are extruded out when they are engaged and therefore the volume of this cavity reduced.This is called as press oil cavity.When gears revolve constantly cavities A and B always pump in and exhaust oil,which is the working principle of the gear pump.Fig.1working principle of gear oil pump4.Pump construction and function4.1This pump series is characterized as simple construction and compactness.Pump body and safety valve are separated.So it’s easy to use and maintain.Quality of the product is guaranteed,for the main parts are made of top-quality steel and precisely processed.4.2Oil pump has the self-absorption function.So it is unnecessary to add oil before working.4.3Lubrication of pump is achieved automatically through the transmission of oil.So no lubrication oil is necessary while working.1.back cover2.gasket3.bush4.bearing stand5.driven shaft6.gear7.driving shaft8.front cover9.soft graphite10.press cover11.pump body12.safety valveFig.2Construction of gear pump4.4Pump bodyTwo holes on the parallel surfaces of pump body are fixed with a pair of gears and four bearing stands.Safety valves are put on the top.Front cover and back cover are in the front and back respectively.Flanges on both side are for connection.Flange connector dimensions are up to the ISO and DIN standards and that of the china state ship-building corporation’s CBM.4.5Gear and shaftAll gears are of spiral gears,the gear and shaft compose of the shaft gear.4.6Bearing stand and bushThe revolving of the shaft gear is backed up by bearing stand and bush that have already been put together as a whole.4.7GasketGasket are inserted into the press surfaces between the pump body and the front and the back covers in order toachieve the better results of the sealing.4.8Shaft seal4.8.1There are two kind of axle-end seals,mechanical seal and packing seal.The seal rings are made of soft graphite which are elastic,high and-low-temperature-resisting,and of chemical stability and self-lubrication.4.8.2Mechnical seal construction is shown as

cap23.washer24.nut25.washer26.adjusting screw27.safety valve spring28.safety valve push pitch29.coverFig.4For pumps with safety valve and without safety valve,please see Fig.44.9.2The working principle of the safety valve is to use spring to control the working of the safety valve.The function of the safety valve is to avoid incidents that might result from too much high exhaust pressure.the breakage of the exhaust pipes or the close of the exhaust oil pipes’valves.When such incidents occur,safety valve opens immediately and the liquid part or even all,will flow back to the pumping in cavity.Safety valve is not used to adjust the capacity of the pump for long.5.Pump installation5.1Before assembling,it is required to check up whether the motor is affected by damp or there is damage to the dust-proof covers of pump’s inlet or outlet,which might lead the dirt things into the cavity.5.2Oil pump and motor are fixed on the base plate.Hooks must hang on the base plate rings.In lifting single pump head,hooks must hang on the inlet or exit flange tubes.Please see Fig.5.5.3Select a dry and bright place so that management people can watch when pump is working.A certain space should leave out if it is close to wall,for it is easy to maintain.Don’t put it at a place where is humid and wet, being exposed to sun and rain,Oil pump should be installed in place above the water level so that it can not befloodedFig.5Hoisting of oil pump5.4The foundation of pump should be stable so that pipes will not be released or vibrated.In order to avoid the deformation of the base plate,bolts should be fixed firmly.If only the pump head is installed on the machinery, the least vibrated place must be chosen.5.5Washing the inside wall of pipes by kerosene before installation in order that no dirt things especially no rubbing matters are allowed to remain in the pipe,because they might cause the damage to the gears.The dimensions of the absorption and exhaustion pipes are by no means smaller than the nominal size of pump. Absorption pipe should be bigger and the shorter the better.Elbow should have bigger radius.Throttle valve should be used on the pipe valves to reduce the resistance.5.6No foot valve is needed for oil pump.But it is suggested to fix a filter gauze at the entrance of the intake pipe to prevent dirt things from entering in pump body.The effective area of the filter gauze should not be two times smaller than that of the dimensions of the tubes.The mouth of the intake tube should be cut to an angle of450.5.7Pump shaft and motor shaft should be installed concentrically.If it is not properly fixed,it might cut off the claw of the shaft couplings when revolving6.Pump operation6.1Start-up6.1.1Before the oil pump to be used,it is required to check up whether all tubes are fixed properly,and open valves of intake oil pipes.6.1.2Revolve the couplings by hand to see if there is an abnormal phenomenon.6.1.3Press the button on shortly before oil pump starts and make it sure the revolving direction is right and everything is perfect.6.1.4If oil pump is in operation,close the control valve of the outlet oil pipes gradually so as to adjust the pressure required.But the adjusted pressure should not be higher than the rated pressure.When oil pump is in constant operation,shaft seal and vibration should be carefully observed.6.2Adjustment of the safety valve6.2.1In normal circumstance,the working pressure of the safety valve is1.5times as against the rated pressure.In case lower pressure is needed,adjust it according to Fig.46.2.2Release the protective cap and unscrew the adjusting nut.6.2.3Make the adjusting screw revolving clockwise and then close gradually the control valve on the outlet tubes to determine whether the returned pressure is that needed.If the requirement cannot be fulfilled through one time of adjustment,you should proceed with several times.6.2.4After the adjustment,screw the adjusting nut and protective cap.6.3Stop workingCut of motor power and close control valve on the outlet tubes.7.Pump disassembly and reassembly7.1Following orders should be followed to disassemble to oil pump.7.1.1Disassemble the couplings on the oil pump shaft end.If it is too tight,use a copper stick to hit it gently and let it out.7.1.2Disassemble the press cover first and then the soft graphite ring or mechanical seal ring.7.1.3Disassemble the front and back covers and take the gasket out.7.1.4Disassemble bearing stand and then take out driving-and driven-shaft gears.7.1.5Disassemble nut and spring washes of the driving-and driven-shaft and then take out the left and-right gears 7.1.6Disassembly of safety valveFirst disassembly the protective cap,gasket and nut,then unscrew the adjusting screws,springs and safety valve push pitch and lastly the valve body and gasket.7.2Oil pump check-outCheck out every part.Worn part must be repaired or replaced.7.3Oil pump reassembly7.3.1The procedure for assembling is nearly the reversal of that for disassembling,i.e.,last disassembled first assemble.But the following points should be noted.7.3.2All the parts must be checked before assembling.7.3.3All the parts that are going to be assembled must be washed with kerosene and lubricated.No dirt things are allowed to enter the inside while assembling7.3.4While assembling the upper and lower bearing stands and the driving and driven gears,the thickness difference of every pair of bearing stand and gear should be less than0.005mm.7.3.5The gap on both gear sides should be adjusted by paper gaskets.Bigger gap will easily cause the leakage and reduce the efficiency,but if the gap is too small,the pump will get a higher temperature quickly or can’t run freely.7.3.6Assembling the soft graphite ring or mechanical seal O-ring by special sleeve.Soft graphite ring must be handled with care and be put in order,and shown in Fig.67.3.7After assembling,use hand to revolve the driving gear,to make sure that it revolves evenly.Fig.6Driving

内啮合齿轮泵的研究说明书
本科毕业设计说明书(题目:×××××××××××××××学生姓名:×××学院:管理学院系别:管理科学系专业:信息管理与信息系统班级:信管04-1指导教师:×××教授/副教授/讲师摘要由于我国生产力以及经济的不断发展,客观上对内啮合齿轮泵的需求量正在不断的增加。
但是我国对于内啮合齿轮泵的研究和探索起步晚,起点低,这就严重制约了我国在内啮合齿轮泵领域的发展速度。
相对于国外知名产品,我国自主生产的内啮合齿轮泵无论在容积效率,输出压力和性能稳定性等方面都存在很大的差距。
本文主要主要内容是通过Pro/E对内啮合齿轮泵进行了建模过程,然后又利用ANSYS软件对内啮合齿轮泵的主要组成部件进行了有限元分析,并根据分析结果提出了相应的优化建议。
关键词内啮合齿轮泵;三维建模;有限元分析;优化建议;Pro/EAbstractIn recent years, Chinese have began to do the research of high-pressure internal gear pumps. But we lack research of internal gear pumps in p a r a m e t r i c d e s i g n, performance and other aspects of basic analysis. So there is a large gap between the current domestic internal gear pumps witn the products of foreign c o u n t r i e s i n o u t p u t pressure, volumetric efficiency and the stability of the products. And China's internal gear pumps have low production and few species.We first drawed the three-dimensional Pro/E of the main structures of the internal gear pump and the assembly drawing. Those draws were saved as the format of IGES,then they were imported into ANSYS. This method of analysis and optimization also has an important significance to design and analyze other parts of pumps, which can make the p u m p h a v e t h e b e s t o v e r a l l p e r f o r m a n c e.Key words internal gear pump;finite element analysis;Pro/E第一章绪论1.1内啮合齿轮泵的概述在液压系统中,经常用到的泵主要是齿轮泵、叶片泵和柱塞泵。
川崎泵K3V泵说明书
川崎K3V系列斜盘式轴向柱塞泵使用说明书川崎重工业株式会社液压泵一、概述:液压泵将原动机的机械能转换成工作液体的压力能。
按其职能系统,属于液压能源元件,又称为动力元件。
液压传动中使用的液压泵都是靠密闭的工作空间的容积变化进行工作的,所以又称为容积式液压泵。
液压泵可分为齿轮泵,叶片泵,柱塞泵(按结构来分)本节主要介绍挖掘机上常用的齿轮泵、柱塞泵的基本概念、工作原理、结构特点、运用原理和维修知识。
1、液压泵的基本性能参数液压泵的主要性能参数是压力P 和流量Q(1)压力泵的输出压力由负载决定。
当负载增加时,泵的压力升高,当负载减小,泵的压力降低,没有负载就没有压力。
所以,在液压系统工作的过程中,泵的压力是随着负载的变化而变化的。
如果负载无限制的增长。
泵的压力也无限制的增高。
直至密封或零件强度或管路被破坏。
这是容积式液压泵的一个重要特点。
因此在液压系统中必须设置安全阀。
限制泵的最大压力,起过载保护作用。
在位置的布置上,安全阀越靠近泵越好。
液压泵说明书对压力有两种规定:额定压力和最大压力。
额定压力——是指泵在连续运转情况下所允许使用的工作压力,并能保证泵的容积效率和使用寿命。
最大压力——泵在短时间内起载所允许的极限压力,为液压系统的安全阀的调定值不能超过泵的最大压力值,最好的是等于或小于额定压力值。
(2)流量Q流量是指泵在单位时间输出液体的体积。
流量有理论流量和实际流量之分理论流量Q0,等于排量q 与泵转数的乘积:Q0=q*n*10-3(L/min)泵的排量是指泵每转一周所排出液体的体积。
泵的排量取决于泵的结构参数。
不同类型泵的排量记算方法也不同。
排量不可变的称为定量泵,排量可变的称为变量泵。
泵的实际流量Q小于理论流量Q0(因为泵的各密封间隙有泄漏)Q= Q0ηV = q.n.ηV /1000(L/min)式中ηV----泵的容积效率ηV =(Q(实际流量)/ Q0(理论流量))*100%齿轮泵的容积效率,ηV≥92%,柱塞泵ηV≥95%泵的泄漏量(漏损)与泵的输出压力有关,压力升高泄漏量(Q0-Q)即ΔQ增加,所以泵的实际流量是随泵的输出压力变化而变化的,而液压泵的理论流量与泵的输出压力无关。
