Problems solved by technology

[0004] Since the pneumatic booster pump needs to be manually operated, there is a risk of overpressure during the hydraulic test; the above two systems operate independently and have a single function. In order to perform hydraulic and pneumatic dual-medium pressure tests, the same workpiece needs to be frequently disassembled, which affects work efficiency and at the same time Increased risk of interface damage

Abstract

The invention provides a dual-medium pressure test device, comprising: a gas booster pump, a gas storage and a high-pressure water storage device; an external gas source is boosted by the gas booster pump and then transferred to the gas storage; After the gas reservoir flows out, it first passes through the first branch, and then is divided into a second branch and a third branch. The second branch leads to the workpiece under test, and the third branch leads to the high-pressure storage. Water tank; the liquid flows into the high-pressure water storage from the water inlet pipe, and the water outlet pipe flows out through the fourth branch, and the second branch and the fourth branch merge into a fifth branch to reach the workpiece under test. Under the premise of solving the dual-medium pressure test, the same workpiece can reduce the frequent disassembly of the interface, which well avoids the risk of equipment damage.

Description

technical field [0001] The invention relates to the field of pressure-bearing capacity tests of workpieces, in particular to a dual-medium pressure test device. Background technique [0002] In order to check whether the pressure bearing capacity of a special workpiece or equipment meets the design requirements, it is necessary to conduct hydraulic and pneumatic tests on the workpiece or equipment. [0003] At present, the common practice of hydraulic test is to use water as the medium, and use a pneumatic booster pump to perform manual pressurization operation; for pneumatic test, high-pressure nitrogen or air is often used to pressurize and output to the target pressure for pressurization operation. [0004] Since the pneumatic booster pump needs to be manually operated, there is a risk of overpressure during the hydraulic test; the above two systems operate independently and have a single function. In order to perform hydraulic and pneumatic dual-media pressure tests, the...
