1, vacuum suction test 1) dry suction vacuum test: In the gasoline pump and the inlet pipe dry state, the camshaft to 50-60R / MIN speed drive gasoline pump, open the outlet and close the inlet , Determination of vacuum suction. 2) wet suction vacuum test: In the gasoline pump and the inlet pipe is full of gasoline, the camshaft to the maximum speed of 25%, 50%, 100% drive the gasoline pump, open the outlet and close the inlet, Determination of vacuum suction. 2, with a manual pump pump device, with a manual pump oil device, to about 50 times per minute speed work, open the outlet and close the inlet, the determination of vacuum suction. 3, the gasoline pump out of time test In the gasoline pump and the inlet pipe dry state, the camshaft to 50-60R / MIN speed drive gasoline pump, open the inlet and the outlet at the same time, measured the outlet began to out Oil time. 4, the maximum closed pressure test Camshaft drive to the highest speed gasoline pump, open the inlet and close the outlet, the maximum closed pressure. 5, the oil test Gasoline pump measured at different temperatures, speed, oil resistance under the oil. 6, the sealing test 1) closed pressure drop: camshaft to the highest speed drive the gasoline pump, open the inlet and close the outlet, at maximum sealing pressure, stop camshaft rotation, and adjust the highest point of the cam and gasoline Pump rocker contact position, and then began to measure the closure of the pressure drop, the measurement time is 1MIN. 2) Leakage: The following two test methods, according to the actual situation of the product choose a: camshaft drive the maximum speed of the gas pump, open the inlet and close the outlet, after 3MIN observe the various parts of the gasoline pump Leakage phenomenon. In the gas inlet of the pump to 98KPA air pressure, close the outlet, immersed in the test oil to maintain 10S or more, observe the various parts of the gas pump leaks. 7, durability test gasoline pump durability test allows intermittent. After the test, the wet vacuum suction, the maximum speed of the oil outlet opening at room temperature when the amount of oil and closed pressure drop and leakage test, and check the various parts of the pump without cracks, deformation and other harmful defects. During the test, the lubricant temperature should be monitored. Lubricating oil should be added or replaced according to the amount of oil and oil.
