阀门实验台又名阀门测试台、阀门测试机，现有卧式、翻转双抱压、立式、智能等类型，现就阀门试验台使用前后的检查与注意事项，
气体增压泵厂家为您做一个解说。
Valve test bench, also known as valve test bench and valve test machine, has horizontal, overturned double holding pressure, vertical, intelligent and other types. Now, the gas booster pump manufacturer will explain the inspection and precautions before and after the use of the valve test bench.
阀门试验台使用前的检查
Inspection of valve test bench before use
（1）检查实验台的机壳是否有裂纹，若有裂纹则不能使用。
(1) Check whether the cabinet of the test bench has cracks. If there are cracks, it cannot be used.
（2）检查阀门测试台的绝缘电阻。用500V绝缘电阻表检测，其绝缘电阻不应小于5MΩ,若低于此值，应打开放水、放气孔，烘干或晒干后再使用。
(2) Check the insulation resistance of the valve test bench. The insulation resistance shall not be less than 5m Ω when tested with 500V insulation resistance meter. If it is lower than this value, open the drain hole and vent hole, and use it after drying or drying.
（3）检查阀门测试台的放气孔、放水孔、放油孔和电缆接头处的封口是否松动，如有松动须旋紧。
(3) Check whether the seals at the vent hole, water drain hole, oil drain hole and cable joint of the valve test bench are loose. If they are loose, they must be tightened.
（4）起动前校正电源正负极，以免水泵倒转，不出水。
(4) Before starting, correct the positive and negative poles of the power supply to prevent the water pump from reversing and no water from flowing out.
（5）阀门测试台的电缆线好不要有接头，若有接头应包扎好，整个电缆线应无破损、折断现象，否则应更换新电缆。另外，电缆线要架空，不要太长。
(5) The cable of the valve test bench should be free of joints. If there are joints, they should be wrapped up. The whole cable should be free of damage and breakage, otherwise it should be replaced with a new cable. In addition, the cable should be overhead and not too long.
（6）开机前对供电线路、开关进行检查，并在地面通电空转3~5min，若运转正常，再放入水中投入使用。
(6) Before startup, the power supply line and switch shall be comprehensively inspected, and the power supply line and switch shall be powered on and idled for 3-5min on the ground. If the operation is normal, it shall be put into water for use.
阀门试验台使用中应注意的事项
Matters needing attention in the use of valve test bench
（1）不同型号的阀门试验台，应按规定的扬程使用，配用的钢管、橡胶管或帆管内径应符合技术要求。
(1) The valve test bench of different models shall be used according to the specified lift, and the inner diameter of the steel pipe, rubber pipe or sail pipe shall meet the technical requirements.
（2）出水管尽可能不要弯曲，及时发现并修补输水管的破裂处，以减少功率损失。
(2) The outlet pipe shall not be bent as much as possible, and the rupture of the water pipe shall be found and repaired in time to reduce power loss.
（3）阀门试验台放入水中或提出水面时，须拉住耳环上的绳子，不能拉电缆线，否则会造成电缆线损坏。
(3) When the valve test bench is put into or lifted out of the water, the rope on the earring must be pulled, and the cable cannot be pulled, otherwise the cable will be damaged.
（4）阀门试验台不能抽排污水或含砂量大的水，尤其是采用机械密封的阀门测试台更应注意这一点。
(4) The valve test bench shall not pump sewage or water with large sand content, especially the valve test bench with mechanical seal.
（5）阀门试验台的潜水深度一般为0.5~3m，并应垂直吊起，不能横卧，更不能陷入泥沙中。
(5) The diving depth of the valve test bench is generally 0.5~3m, and it should be lifted vertically. It is not allowed to lie horizontally, let alone sink into the sediment.
（6）阀门试验台电源应按规定选用，电源与水泵的距离不能过远，电压应在正常值的±10%之内，并在电源或水泵处埋设一根1m以上的铁棍作地线，以确保。电源须接地可靠，加装漏电保护器。另外，尽量避免在电源电压过高或过低时开机，电压过高，会引起电动机过热而烧坏绕组；电压过低，则电动机转速下降，会造成起动绕组长时间发热，甚烧坏绕组和电容器。
(6) The power supply of the valve test bench shall be selected according to the regulations. The distance between the power supply and the water pump shall not be too far. The voltage shall be within ± 10% of the normal value. An iron rod of more than 1m shall be buried at the power supply or the water pump as the ground wire to ensure safety. The power supply must be grounded reliably and equipped with leakage protector. In addition, try to avoid starting the machine when the power supply voltage is too high or too low. If the voltage is too high, the motor will overheat and burn out the winding; If the voltage is too low, the motor speed will drop, which will cause the starting winding to heat up for a long time, and even burn out the winding and capacitor.
（7）阀门测试台应采用断路器作控制设备，也可以采用三刀刀开关，但须装上6A的电熔丝。
(7) The valve test bench shall use a circuit breaker as the control equipment, or a three blade switch, but 6A electric fuse shall be installed.
The valve test bench is used by submerging the pump and motor into the water. If the technical performance fails to meet the requirements, it will not only not be able to pump water, but also may cause safety accidents. Therefore, it is necessary to pay attention to the maintenance of the valve test bench. For details, please visit our website http://www.feileisi.com Consult and understand.
