Problems solved by technology

For example, the test tooling of the water pump is in the water for a long time, and the tooling is easy to rust, which leads to a decrease in the cleanliness of the water. The water in the water tank needs to be replaced regularly, resulting in waste of water resources. The test equipment needs regular maintenance; Able to operate a test equipment, after the test is completed, the water on the pump must be blown off drop by drop, the test efficiency is low, and it is not suitable for mass product testing; and the existing water test equipment has a low level of intelligence

Abstract

The invention discloses a test bench for sealing property of a water pump. The test bench comprises a rack, wherein the rack is provided with a tool lower template and a tool upper template; the tool lower template is provided with a gasket for sealing one end of the water pump and a ventilation hole which is communicated with the other end of the water pump; the tool upper template is provided with a tool pressing rod; and the lower part of the rack is provided with a gas pump which is communicated with the ventilation hole. By using gas as a detection medium, the sealing property of the water pump is tested by detecting leakage of the gas, the test is controlled by an operating panel, a tool and the water pump are not in contact with water, blow-drying treatment is not required to be performed on the tested tool and the water pump when the test is finished, test equipment has low maintenance frequency and high test efficiency, and the test bench is suitable for testing a large scale of products.

Description

technical field [0001] The invention relates to the technical field of water pump testing, in particular to a water pump tightness testing platform. Background technique [0002] Before the water pump leaves the factory, the tightness of the water pump should be checked to avoid the delivery of products with quality defects. [0003] At present, water pumps are generally tested for tightness with water, and water testing has relatively low requirements for test equipment, but there are still many shortcomings. For example, the test tooling of the water pump is in the water for a long time, and the tooling is easy to rust, which leads to a decrease in the cleanliness of the water. The water in the water tank needs to be replaced regularly, resulting in waste of water resources. The test equipment needs regular maintenance; One test equipment can be operated. After the test is completed, the water on the pump must be blown off drop by drop. The test efficiency is low and it i...
