Problems solved by technology
Take the full-featured test bench of the pump as an example. The test bench includes two auxiliary pumps, a test pump and its related pipelines. Pump head; when conducting reverse flow tests, it is sometimes necessary to reverse the inlet and outlet of the auxiliary pump, which increases the workload and inefficiencies
It can be seen that the existing test bench still has a lot of room for improvement.

The invention belongs to the technical field of experiment tools, and particularly discloses an all-working-condition testbed for a pump. The all-working-condition testbed for the pump comprises a test pump, an auxiliary pump, a water tank, a gas tank, a surge tank, a flowmeter, a vacuum pump, an air compressor, a gas-liquid mixer, gas path control valves I-III, water path control valves IV-X andpipelines thereof; only one test pump, one auxiliary pump and one related pipeline system are used; experiments like external characteristic test, all characteristic test, gas-liquid two-phase fluid test and cavitation test of the pump can be finished by adjusting the opening and closing of the auxiliary pump and the water path control valves IV-X; and in the testing process, dismounting of the test pump and the auxiliary pump is not needed, the workload is reduced, and the working efficiency can be greatly improved.
Description
technical field [0001] The invention belongs to the technical field of experimental tooling, and in particular relates to a full working condition test bench for pumps. Background technique [0002] A pump is a machine that converts the mechanical energy of the prime mover into liquid energy. The performance test of the pump mainly includes the external characteristic test, the full characteristic test, the gas-liquid two-phase flow test and the cavitation performance test of the pump. Existing test benches are usually able to complete one or several of the above tests. If other tests are required, the pipeline usually needs to be modified; in addition, some test benches have higher requirements for test equipment, and two test benches are required for one test. Even more pumping aids. Take the full-featured test bench of the pump as an example. The test bench includes two auxiliary pumps, a test pump and its related pipelines. The head of the pump; when conducting the re...
