Problems solved by technology

The utility model has small volume, reasonable structural design, small footprint, improved applicability of the test device to the use site, and is convenient to move, and the operation is relatively simple, which helps to reduce the working intensity and detection quality of the testers; There is a lifting device at the inner bottom of the detection box. The lifting device can make the first water pump at different heights, so that the water pressure of the first water pump at different heights can be tested. Although the device is small in size and occupies a small area, However, when the water pump is tested by P-Q and T-Q, the test accuracy cannot meet the requirements. When the lift of the pump is tested, the adjustable height of the lifting platform of the device is relatively limited, which cannot meet the test requirements.

Abstract

The invention relates to a performance test system for an indoor water pump. The performance test system comprises a circulating pool, a circulating pipeline and a water pump to be tested, wherein thecirculating pool is arranged on the ground, the circulating pipeline is connected with the circulating pool, and the water pump to be tested is arranged in the circulating pipeline; the circulating pipeline comprises a water inlet pipe and a water outlet pipe, and liquid in the circulating pool is drawn out by the water pump to be tested through the water inlet pipe and is discharged into the circulating pool through the water outlet pipe; the water pump to be tested is arranged in a liftable mechanism and is connected with a driving motor through a shaft coupler, and a torque sensor and a speed measuring instrument are arranged on the shaft coupler; pressure sensors are correspondingly arranged on pipelines of a water inlet and a water outlet of the water pump to be tested; a flowmeter is arranged in the circulating pipeline; and a temperature regulating unit used for regulating liquid temperature and a temperature sensor are arranged in the circulating pool. Compared with the priorart, the system can test various performances of the water pump and can realize lifting regulation in a larger range so as to meet a high-standard lift test. The system operation is simple and convenient, the testing process has high degree of automation, and the testing precision is high.

Description

technical field [0001] The invention relates to the field of water pump performance testing, in particular to an indoor water pump performance testing system. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. The technical parameters of pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotati...
