3 terms and definitions

GB/T 7021, GB/T 7785, ISO 17769 and the following terms and definitions apply to this document. 3.1 Test item itemstobetested Any part, component, component, pump or pump unit for hydrostatic test. Note. Do not include mechanical seals, connecting bolts, end caps, etc. installed in the pump or separate seal part, but these parts can withstand the test pressure.

4 General

4.1 In general, all test pieces of the pump shall be subjected to a hydrostatic test at ambient temperature. Only the pump is manufactured in larger batches and The sampling plan can only be considered when the manufacturer confirms that it is suitable for sampling. See Appendix A for a random sampling plan. Note. The purpose of the hydrostatic test is to test the test piece by applying a pressure of more than the maximum working pressure to the test piece. Whether there is a leaking and leaking phenomenon in the junction of the body to determine whether the test piece is qualified. 4.2 double-shell pump, multi-stage pump, the overall gear box drive pump test pieces, reciprocating displacement pump cylinder block and other pressure situation is complex Test pieces can be tested separately according to different pressures. 4.3 independent pressure chamber should be tested separately, the test process with its adjacent chamber should not exert pressure. 4.4 In order to avoid overloading the reciprocating pump crankshaft, the components of the recirculation suction section should be supported or disconnected from the crankshaft.

5 test time points

In the manufacturing process of the test piece, the manufacturer shall arrange sufficient time for the test. The test time points are as follows. After finishing ......
