Valve test bench installation requirements First, the equipment installation: the school level or placement of your equipment fixed with concrete footing bolts. Second, the selection of N32-46 # common hydraulic oil, N32-46 # anti-wear hydraulic oil or 20-30 # mechanical oil into the fuel tank, fuel oil level gauge can not be less than the minimum. Third, the power, press the start button pump, check the motor rotation direction is correct (clockwise) for 5-1 O-minute no-load running, adjust the pump pressure in the 5 0MPa test machine, a variety of actions, check the piping for leaks and found negative phenomena, should be shut down immediately excluded. Fourth, the test medium: water is convenient and does not pollute the environment, etc., which are widely used, to ensure that the valves were tested and the test machine is not corrosive media requirements needed. In the tank, add rust or used oil as the test medium. Fifth, test valves, the valves were tested according to the first test pressure, insisted that "the pressure required to compress cylinder table" in the hydraulic clamp system pressure, the boost pressure regulator, high pressure booster is strictly prohibited to prevent deformation of the valve damage were tested. Sixth, the hydraulic pump to work for voltage before adjustment and good electric contact pressure gauge test valve pressure was the same, and then to work. Cast iron valves shall not use the hammer, the valve in the test, the operator should pay attention to safety, proper use, especially when the media attention to the test pressure is too high cast iron valve damage, the valve test is completed, the pressure within the valve should be drained after can relax the axial compressor. Seven, the pressure gauge test equipment must be approved by the local authorities measure their accreditation certificate should be valid, the pressure gauge of range can not be less than 15 times the test pressure, accuracy is not less than 1.5.

一、设备安装：校好设备安置水平或用混凝土固定底脚螺栓。二、选用N32—46#普通液压油，N32—46#抗磨液压油或20—30#机械油，注入油箱，油量不能低于油位计下限。三、接通电源，按油泵启动按钮，检查电机转动方向，是否正确(顺时针方向)进行5—1 O分钟空载运转后，调节油泵压力在5 0MPa进行试机，各种动作，检查各管路有无泄漏，发现不良现象，应立即停机排除。四、试验的介质：水具有方便，不污染环境等优点，因而应用广泛，要确保对被试阀门不会腐蚀及在测试机介质要求所需要。在水箱中，添加防锈剂或者常用油作试验介质。五、测试阀门时，首先根据被试阀门试验压力，要求参照《压紧油缸所需压力对照表》中液压压紧系统压力值，进行增压压力调节，严禁增压压力值超高、防止被试阀门变形损坏。六、液压供压水泵开始工作前，先调节好电接点压力表与被试验阀门压力相同，然后进行工作。铸铁阀门不得用锤击，阀门在试验中，操作人员应注意安全，正确使用，特别注意测试铸铁阀门时介质压力过高破损，阀门试验完毕，应将阀门内压力排尽后才可放松轴向压机。七、压力试验装置的压力表必须经当地计量部门鉴定合格其合格证应在有效期内，压力表的量程不能低于测试压力15倍，精度不低于 1．5级。
