2测试台运转前准备工作的安全须知
检查设备现状和完好状态,检查各管路的压力表,按钮在运输过程中是否损坏,当测试台发现故障和液压系统出现异常噪音时,要切断电源停止工作,排除故障,严禁测试超出试压范围的阀门.
3.有关电器方面的安全须知
测试台采用三相四线,交流电源：电压380v,50Hz,控制电路电压220v,50HZ:非专业工作人员禁止触及电力控制装置以免危险.由于测试台按钮较多,因此提醒操作人员必须对安全问题高度重视,未经过学习本须知,严禁上岗.
检查电源接地线是否可靠,线径是否符合要求.
检查电源相续是否正确.
检查信号指示是否正确.
测试台电器出现故障时,应首先关闭电源,故障不解除,任何人不准送电.
电器维修人员必须按电工操作规程穿电工绝缘工具进行工作,维修期间必须有专人看管,或在电源处挂牌警示.

2 test operation before the preparation work of safety
Check the equipment situation and intact state, check the pipeline pressure meter, a button in the transport process is damaged, when the test platform hydraulic system fault and abnormal noise, to cut off the power to stop working, troubleshooting, no testing beyond range of valve pressure test.
3 related aspects of electrical safety
Test bench adopts three-phase four wire, AC power supply voltage: 380V, 50Hz, voltage 220V control circuit, 50HZ: non professional staff ban touched power control device in order to avoid the danger. Because the test button is more, so to remind the operator must attach great importance to safety problems, not after learning this information, no induction.
Check power supply grounding wire is reliable or not, whether it meets the requirements of wire diameter.
Check power continued correctly.
Check signal indicating whether the correct.
Test the electrical failure, should first turn off the power supply, fault is not lifted, no person shall be allowed to send electric.
Electrical repair personnel must be in accordance with the electrical operation in electrical insulating tools, repair period must have special care, or in the power department listing warning.
