It is recommended that air pressure measures 90 psig at the tool with the trigger fully depressed and no load applied to the tool. Higher pressure (over 90 psig; 6.2 bar) raises performance beyond the rated capacity of the tool, which will shorten tool life and could cause injury.Always use clean, dry air. Dust, corrosive fumes and/or water in the air line will cause damage to the tool. Drain water from air lines and compressor prior to running tool. Clean the air inlet filter screen weekly. The recommended hookup procedure can be viewed in the above figure.The air inlet used for connecting air supply has standard 1/4" NPT. Line pressure should be increased to compensate for unusually long air hoses (over 25 feet). Minimum hose diameter should be 3/8" I.D. and fittings should have the same inside dimensions and be tightly secured.Ensure an accessible emergency shut off valve has been installed in the air supply line and make others aware of its location.LUBRICATIONLubricate the air motor daily with high quality air tool oil. If no air line oiler is used, run 1/2 oz. of oil through the tool. The oil can be squirted into the tool air inlet or into the hose at the nearest connection to the air supply, then run the tool. A rust inhibitive oil is acceptable for air tools.WARNING: After an air tool has been lubricated, oil will discharge through the exhaust port during the first few seconds of operation. The exhaust port must be covered with a towel before applying air pressure to prevent serious injury.OPERATIONThis ratchet is rated at 1/4" USS bolt size. Rat i ng must be down grad e d for spring U bolts, tie bolts, long cap screws, double depth nuts, badly rust e d conditions and spring fas t en e rs as they absorb much of the impact power. When possible, clamp or wedge the bolt to prevent springback.Soak rusted nuts in penetrating oil and break rust seal before removing with impact ratchet. If nut does not start to move in three to five seconds use a larger size impact ratchet. Do not use impact ratchet beyond rated capacity as this will drastically reduce tool life. The reverse button is used to change the direction of the tool. When the button is turned to the left, the tool is in a for w ard or right hand direction. When the button is turned to the right, the direction is in reverse or left hand direction.NOTE: Actual torque on a fastener is directly related to joint hardness, tool speed, condition of socket and the time the tool is allowed to impact. Use the simplest possible tool-to-socket hook up. Every connection absorbs energy and reduces power. NOTE: Always turn off the air supply, drain hose of air pressure and detach tool from air supply before installing, removing or adjusting any part or accessory on this tool, or before performing any maintenance on this tool. TROUBLESHOOTINGOther factors outside the tool may cause loss of power or erratic action. Reduced compressor output, excessive drain on the air line, moisture or restrictions in air pipes or the use of hose connections of improper size or poor conditions may reduce air supply. Grit or gum deposits in the tool may cut power and may be corrected by cleaning the air strainer and flushing out the tool with gum solvent oil or an equal mixture of SAE #10 and kerosene. If outside conditions are in order, disconnect tool from hose and take tool to your nearest authorized service center.WARRANTYCornwell Quality Tools Company (“Cornwell”) warrants this product against defects in material and workmanship for a period of ONE (1) YEAR from the date of original retail purchase.

250检测台说明书1
一、产品概述JFM-Y250W/32型阀门密封检测机床，是按GB/T13927-92《通用阀门压力试验》、ZBJ16006《阀门的试验与检验》等有关标准设计制造的。
本产品具有设计先进、布局合理、结构紧凑、性能可靠、操作及维修方便等特点。
主要适用于公称通径Dn50～Dn250、结构长度130~680mm以内的直通式法兰连接的球阀、截止阀、闸阀、蝶阀及焊接式阀门的密封试验。
是阀门生产厂家、石油化工厂、电厂、质量检查部门等单位的一种理想检测设备。
二、产品主要技术参数性能参数见表一，测试水压见表二表一性能参数表表二测试水压表三、工作原理该阀门密封检测机床采用液压驱动吊装、夹持阀门，注水泵站注水并予加水压、增压缸提高水压的方式进行工作。
液压泵站置于控制柜内、注水泵站置于右箱罩内并与机床主体形成一体；外设气源接口，内设气路连接点，实现液压、气压实验功能。
四、主要结构阀门密封检测机床主要有机体、夹紧缸、增压缸、举升装置、液压泵站、电气控制系统及注水泵站等组成（如图所示）。
五、操作方法1．合上电源，按油泵电机启动开关按钮，启动油泵电机。
2．按被测阀门实验要求设定保压定时时间参数；打开右箱罩端盖，调整试压泵压力控制表参数至试验压力的10%~50%；空载运行举升缸、夹紧缸、注水泵站及溢流阀、减压阀正常后，机床就可以正式投入使用了。
3．按下举升、下降点动开关，将被测阀门吊至机身中间压盘中心高度。
吊装时，注意调节溢流阀、减压阀手柄控制系统压力，以适应不同阀门的起重力量。
4．按下夹紧开关按钮，将阀门夹紧，此时系统压力调至1-3MPa。
夹紧后，点动下降开关使阀门所受起吊力减至最小（加压测试时举升装置最好不脱离阀门），再调整系统压力至规定值（见表二）并观察夹紧压力表。
按下停止开关，夹紧动作完成，然后将系统压力调至6-8MPa。
5．按下卸压开关，增压缸至行程终点后，按下停止开关。
开启进水多路球阀（手柄斜向上45°为进水位）及出水球阀，按下水泵启动开关，向被测阀门内注水；待出水口出水后，关闭阀门密封件，水泵向被测阀门内加压注水，达到予压力(此压力值不能高于阀门试验压力的60%)后，水泵停机，再关闭进水多路球阀（手柄处于水平位置），此时水泵若不自动停机再按水泵停止开关。

1W(VAR3,130)
user variable value, type ....................................................... 1VMATH(A,=,VAR3)
The ViX user variable functionality permits the user to read and write up to 8 user-defined variables. These variables can be used to perform mathematical operations and also in combination with certain EASI code commands, where they can be used in selected data fields or in evaluation statements. User variable data can be set directly by the user or control system, via the serial communications port or user program using the VAR command, or indirectly within a program structure by using the VMATH command. User variables may also be used in combination with the ViX system variables, User variable data is only stored when a save (SV) command is executed. Following a reset or a power cycle, the user variable data will be returned to the values current at the time of the last save command. If no save command is executed prior to a reset, all user variable data will be lost.
