Crank case air impermeability testing table and operating method thereof

Abstract

The invention discloses a crank case air impermeability testing table and an operating method thereof. The crank case air impermeability testing table comprises a testing box, supporting legs, a testing table body, an external plate, a support, an illumination lamp, an installing plate, a pressure meter, a control plate, startup buttons, an air tube, a sliding rail, a pressure plate, a positioningblock, a fixing clamp, a magnetic air valve, a supporting plate, a pressure transmitter and an air cylinder. The crank case air impermeability testing table has the advantages that the supporting legs are installed at the bottom of the testing box through screws and are adjustable in height, and the whole device is adjusted to reach the height suitable for an operator so that the operation can beconvenient and effort can be saved. The illumination lamp is arranged on the support at the upper portion of the testing table body, the lighting demand during detection can be met, two symmetric startup buttons are fixed to the test table body and are serially connected, the pressure plate is started with two hands to act so as to ensure human safety, a plugging device matched with a crank caseis fixed in a fixing clamp, the cavity of the crank case is sealed as much as possible, and accordingly the purpose of improving the detection precision is achieved.

Description

technical field [0001] The invention relates to a crankcase test bench, in particular to a crankcase airtight test bench and an operation method thereof, which belong to the field of industrial testing equipment. Background technique [0002] Air tightness testing is applied to the tight integrity assessment of aircraft, automobiles, ships and internal containers. It is a quality control application developed for the transport sector, military sector and basic industries to improve the airtightness of vehicles, aircraft, ships, etc. [0003] As the power source of compressed air, air compressors are used in all walks of life in machinery manufacturing. As an important part, the crankcase in the air compressor is particularly important for its airtightness. A crankcase with poor airtightness will affect the performance of the air compressor. Due to the stability of the work, the air pressure of the compressed air output by the air compressor cannot reach the design target. Si...
