Valve test bench installation requirements
First, the installation of equipment: a good school equipment placement level or with concrete anchor bolts. Second, use N32-46 # ordinary hydraulic oil, N32-46 # anti-wear hydraulic oil or 20-30 # mechanical oil, into the fuel tank, the fuel can not be lower than the lower limit of the fuel gauge. Third, the power, press the pump start button, check the motor direction of rotation, is correct (clockwise) for 5-1 O minutes after no-load operation, adjust the pump pressure test machine at 50MPa, various actions, check each Pipeline leakage, found that the phenomenon of bad, should be immediately shut down to exclude. Fourth, the test medium: water has the advantages of convenience, does not pollute the environment, which is widely used, to ensure that the valve will not be corroded and tested in the media requirements required. In the tank, add rust inhibitor or common oil as test medium. Fifth, the test valve, the first test valve under test pressure, requiring reference to "compaction cylinder pressure required pressure table" in the pressure hydraulic system pressure, supercharger pressure control, non-supercharger pressure is super high, to prevent being Test valve deformation damage. Sixth, hydraulic pressure pump Before starting to work, first adjust the pressure gauge and the electrical contact pressure is the same as the test valve, and then work. Cast iron valve shall not be pounding, the valve in the test, the operator should pay attention to safety, proper use, with particular attention to test the cast iron valve medium pressure is too high damage, the valve test is completed, the valve pressure should be drained to relax the axial press. Seven, pressure test device pressure gauge must be certified by the local measurement department of the certificate should be valid, the pressure gauge range can not be less than 15 times the test pressure, the accuracy of not less than 1.5.
