The invention discloses a negative pressure meter for compressor testing, and relates to the technical field of compressor testing. The negative pressure meter comprises a bottom plate, wherein a limiting box is arranged at the top of the bottom plate, a T-shaped plate is arranged in the limiting box and slidably connected with the limiting box, a mounting plate is arranged at the top of the T-shaped plate, a limiting device and an adjusting device are arranged between the bottom of the mounting plate and the top of the bottom plate, a water column pipe, a compressor body and an extrusion device are arranged at the top of the mounting plate, the extrusion device abuts against the water column pipe, a floating ball is arranged in the water column pipe and slidably connected with the water column pipe, and the adjusting device comprises a stepping motor. By arranging the water column pipe and the floating ball, plateau pressure measurement can be simulated, the water column pipe is used for replacing a negative pressure meter, different pressures can be reflected through pressure rising and falling of the water column pipe, the accuracy of gas testing is further improved, the floating ball arranged in the water column pipe can serve as a floating valve, water in the water column pipe is prevented from being sprayed out of the water column pipe, and the use is relatively convenient.
Description
technical field [0001] The invention belongs to the technical field of compressor testing, in particular to a negative pressure gauge for compressor testing. Background technique [0002] The existing negative pressure gauge in the compressor still has certain shortcomings when using the negative pressure gauge in the compressor to test the gas pressure. The gauge cannot be used normally, which reduces the accuracy of the compressor negative pressure gauge during the test, and cannot accurately and efficiently test the gas. Therefore, we improved this and proposed a negative pressure gauge for compressor testing. Contents of the invention [0003] The purpose of the present invention is to provide a negative pressure gauge for compressor testing to solve the existing problem: when the negative pressure gauge in the existing compressor is used in a plateau environment due to the high pressure, the negative pressure gauge will If it cannot be used normally, the accuracy of ...
