Electronic expansion valve rotary type multiple stations integration testing device

Abstract

The invention discloses an electronic expansion valve rotary type multiple stations integration testing device. The device comprises a valve loading station, a valve closing station, a valve closing flow determination station, a valve opening point determination station 1, a valve opening point determination station 2, a zeroload flow determination station, a high pressure valve opening station, a loading flow determination station, a low flow determination station, a high flow determination station, a pulse setting station, a stationary work table, a swivelling angular table, an index dial, a control system and the like. During an operation, an operation worker takes down a measured valve from the valve loading station and put a valve to be measured in place after scanning. The valve to be measured is conveyed to each appointed station to realize operations of valve closing flow determination, valve opening point determination, maximal valve opening differential pressure, multi-pointflow determination, factory pulse setting and the like. In a present electronic expansion valve testing device, automation degree is low, a new clamp needs to be installed after testing each index, and a device can only test a performance index. According to the testing device in the invention, the above disadvantages are overcome, working time is saved and automation degree of testing is raised.

Description

technical field [0001] The invention relates to a testing device for an electronic expansion valve, in particular to a rotary multi-station comprehensive testing device for an electronic expansion valve. Background technique [0002] In the refrigeration system, the throttling mechanism, the compressor, the condenser, and the evaporator are called the "four major parts" of the refrigeration system. They are one of the essential components in the refrigeration system. Controls the flow rate of the evaporator refrigerant and the superheat of the evaporator outlet. As a throttling mechanism, the electronic expansion valve is more and more widely used with the increasing popularity of frequency conversion air conditioners. Great advantages. However, the current electronic expansion valve testing equipment has disadvantages such as low degree of automation, time-consuming installation of test pieces, and time-consuming replacement of tooling and fixtures. In particular, one equ...

Problems solved by technology

However, the current electronic expansion valve testing equipment has disadvantages such as low degree of automation, time-consuming installation of test pieces, and time-consuming replacement of tooling and fixtures. In particular, one equipment can only test one performance index, resulting in low overall efficiency of testing. The development of a clamping completes all performance tests. , Faster and more convenient electronic expansion valve flow test equipment and its testing process and usage method, to meet the higher demand of electronic expansion valve manufacturers, is an effective way to improve the production efficiency of electronic expansion valve products
