Detecting device for piston rod bounce value

Abstract

The invention relates to the technical field of compressor working condition detection, and discloses a detecting device for a piston rod bounce value, which comprises a packing box assembly, a compressor control system, a middle body cover plate, a measurement mounting bracket, a compressor middle body, a horizontal measuring instrument, a vertical measuring instrument, a first data transmissioncable, and a second data transmission cable. The compressor control system includes an A / D analog input module, a piston rod is mounted inside the packing box assembly, and the measurement mounting bracket includes a horizontal plate. The detecting device for the piston rod bounce value can monitor the bounce of the piston rod of the compressor at all times, so as to obtain the bounce value of thepiston rod in the whole process of the compressor operation, and timely reflect the change of the working condition of the piston rod of the compressor. The compressor is enabled to stop or work normally for different operating conditions of the compressor piston rod, which is beneficial to monitor the performance of the compressor and reduce and control the compressor equipment failure.

Description

technical field [0001] The invention relates to the technical field of compressor working condition detection, in particular to a detection device for the jumping value of a piston rod. Background technique [0002] The natural gas compressor is a continuous working device, and its service life is determined by the balance stability and tightness of the seal. The beating of the piston rod in the compressor is the primary factor that determines the sealing performance of the compressor. Therefore, it is particularly important to detect the jumping of the piston rod in motion, which is also one of the measures to improve the performance of the compressor. [0003] The existing detection method for the jumping value of the piston rod is generally as follows: when the compressor is running, remove the middle body cover plate of the compressor, install the dial indicator on the frame close to the compressor stuffing box assembly, and the dial indicator The measuring head is pla...
