閥門(mén)試驗臺的工作流程
Workflow of valve test bench
閥門(mén)試驗臺是用于閥門(mén)和檢維修后閥門(mén)的可靠的密封性質(zhì)量 , 閥門(mén)生產(chǎn)和閥門(mén)解體檢維修后的后一個(gè)工序是試壓檢測。
The valve test bench is used for reliable sealing quality of valves and valves after inspection and maintenance. The next process after valve production and valve disassembly and maintenance is pressure test.
閥門(mén)試驗臺的使用過(guò)程中，發(fā)現手工操作電動(dòng)試壓泵經(jīng)常會(huì )使閥門(mén)的壓力值超過(guò)試驗規定的壓力值，嚴重時(shí)會(huì )致使壓力值顯示表盤(pán)的指針打彎、使閥門(mén)造成損傷或破壞，甚會(huì )造成人身事故。
During the use of the valve test bench, it is found that the manual operation of the electric pressure test pump will often make the pressure value of the valve exceed the pressure value specified in the test. In serious cases, it will cause the pointer of the pressure value display dial to bend, damage or damage the valve, and even cause personal safety accidents.
閥門(mén)試驗臺利用本智能裝置就能很好地解決上述問(wèn)題。當壓力值達到規定值時(shí)，本裝置會(huì )自動(dòng)關(guān)閉電動(dòng)試壓泵的開(kāi)關(guān)，同時(shí)報警裝置進(jìn)行報警。
The valve test bench can solve the above problems by using the safety intelligent device. When the pressure reaches the specified value, the device will automatically turn off the switch of the electric pressure test pump, and the alarm device will give an alarm at the same time.
閥門(mén)試驗臺的電控部分由主電路、控制電路和信號指示電路三部分組成。多功能電控閥門(mén)試驗臺主要由操作面板、硅整流電路板、電動(dòng)裝置控制電路板、圓形連接器插座板和移動(dòng)式臺體等部件組成。
The electric control part of the valve test-bed consists of main circuit, control circuit and signal indicating circuit. The multifunctional electric control valve test-bed is mainly composed of operation panel, silicon rectifier circuit board, electric device control circuit board, circular connector socket board, mobile platform and other components.
閥門(mén)試驗臺使用前的檢查
Inspection of valve test bench before use
（1）檢查實(shí)驗臺的機殼是否有裂紋，若有裂紋則不能使用。
(1) Check whether the shell of the test bench has cracks. If there are cracks, it cannot be used.
（2）檢查閥門(mén)測試臺的絕緣電阻。用500V絕緣電阻表檢測，其絕緣電阻不應小于5MΩ，若低于此值，應打開(kāi)放水、放氣孔，烘干或曬干后再使用。
(2) Check the insulation resistance of the valve test bench. Use a 500V insulation resistance meter to test, and the insulation resistance shall not be less than 5m Ω. If it is lower than this value, open the drain hole and vent hole, and use it after drying or drying.
（3）檢查閥門(mén)測試臺的放氣孔、放水孔、放油孔和電纜接頭處的封口是否松動(dòng)，如有松動(dòng)必須旋緊。
(3) Check whether the seals at the vent hole, water hole, oil hole and cable joint of the valve test bench are loose. If they are loose, tighten them.
（4）起動(dòng)前校正電源正負極，以免水泵倒轉，不出水。
(4) Correct the positive and negative poles of the power supply before starting to prevent the water pump from reversing and no water from flowing out.
（5）閥門(mén)測試臺的電纜線(xiàn)*好不要有接頭，若有接頭應包扎好，整個(gè)電纜線(xiàn)應無(wú)破損、折斷現象，否則應更換新電纜。另外，電纜線(xiàn)要架空，不要太長(cháng)。
(5) The cable * of the valve test bench shall not have a joint. If there is a joint, it shall be wrapped up. The whole cable shall be free of damage and breakage. Otherwise, it shall be replaced with a new cable. In addition, the cable should be overhead and not too long.

氣體增壓泵廠(chǎng)家提醒您，開(kāi)機前對供電線(xiàn)路、開(kāi)關(guān)進(jìn)行檢查，并在地面通電空轉3~5min，若運轉正常，再放入水中投入使用。
(6) The manufacturer of gas booster pump reminds you to check the power supply line and switch before starting the machine, and power on the ground to idle for 3~5min. If the operation is normal, put it into water for use.
