Automatic water filling type leak tester for water pump

Abstract

The invention discloses an automatic water filling type leak tester for a water pump. The automatic water filling type leak tester for the water pump comprises a support of a tool table, a water filling device and an alarm device. A plugging device and a clamping device which correspond to the water pump are arranged on the tool table, wherein the plugging device comprises a plurality of plugging units which are in one-to-one correspondence to a water inlet and a water outlet of the water pump, the water filling device comprises a liquid storage device of which the inner cavity comprises a liquid storage area and a non-liquid area, the liquid storage device is connected with at least one plugging unit through a water filling pipe, when the plugging units plug the water inlet and the water outlet of the water pump, the liquid storage area is communicated with the inner cavity of the water pump through the water filling pipe, the non-liquid area is connected with an air source through an air pipe, a pressure detector is arranged on the air pipe, and an exhausting device is arranged on the non-liquid area. By means of the automatic water filling type leak tester for the water pump, water is injected into the water pump by air pressure, and the air tightness of the water pump is judged by detecting pressure condition, structure is simple, and the detection is sensitive and accurate.

Description

technical field [0001] The invention relates to the field of detection of water pump tightness, in particular to a water pump automatic irrigation type leak tester. Background technique [0002] During the operation of the water pump, if the sealing performance and effect of the water pump are not good, it will not only seriously affect the safe operation of the water supply system, but also easily cause a lot of waste of manpower and financial resources. Therefore, it is necessary to accurately detect the sealing performance of the water pump. Existing water pump leak testing methods include manual operation detection and detection through leak testing equipment. During manual operation detection, each product needs to manually seal the gap many times. Not only is the labor intensity high, the operation progress is slow, and the probability of human error increases. Moreover, the airtightness of the product is not easy to detect, which increases the production cost. Howeve...
