Abstract

The invention relates to a work indication platform for an electronic vacuum pump. The work indication platform for the electronic vacuum pump comprises the electronic vacuum pump which is connected with a driving source; an air outlet of the electronic vacuum pump is connected with a pressure simulation air chamber, and an air inlet of the electronic vacuum pump is connected with an air storage tank; the pressure simulation air chamber is connected with a first air pump, a solenoid valve and a first vacuum degree sensor; the air storage tank is connected with a second air pump and a second vacuum degree sensor; and the driving source, the first vacuum degree sensor, the second vacuum degree sensor, the first air pump, and the second air pump are all connected with a programmable logic controller which is connected with input and output equipment. The work indication platform can simulate the running condition of the vacuum pump in a low-pressure environment of a plateau in a normal space, and saves the cost and space volume.

Description

technical field [0001] The invention relates to the field of electronic vacuum pump testing, in particular to an electronic vacuum pump work display platform. Background technique [0002] At present, the electronic vacuum pump is one of the important components of the automobile braking system. Due to its particularity, there are very few dedicated test equipment, especially the test equipment that can simulate the low-pressure plateau environment. In the traditional method, the high-altitude environmental test of the electronic vacuum pump needs to be carried out in a relatively large-volume environmental chamber, and the air pressure, temperature, humidity, etc. in the environmental chamber can be adjusted to obtain the high-altitude environment. Electronic vacuum pump performance. Such environmental chambers are very expensive and place very high demands on the control system. Contents of the invention [0003] The technical problem to be solved by the present invent...
