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.
