Embodiment 1

[0025] Such as figure 1 , figure 2 with image 3 As shown, the natural gas compressor piston rod runout measuring device includes a compressor control system 5, and also includes a horizontal measuring instrument 1, a measuring mounting frame 2, a vertical measuring instrument 3, two data transmission cables 6 and a middle body cover 4. The measuring mounting frame 2 is fixedly connected to the middle body cover 4, the level measuring instrument 1 and the vertical measuring instrument 3 are both fixedly connected to the measuring mounting frame 2, and the horizontal measuring instrument 1 is axially located in the horizontal direction, The straight measuring instrument 3 is axially located in the vertical direction, and the horizontal measuring instrument 1 and the vertical measuring instrument 3 are respectively connected to the compressor control system 5 through a data transmission cable 6.

[0026] Compressor control system 5 can use GE9070PLC compressor instruments and equi...

Embodiment 2

[0028] This embodiment is further limited on the basis of embodiment 1, such as figure 1 , figure 2 with image 3 As shown, the measurement mounting frame 2 includes a right wing plate 21, a web 22, and a left wing plate 23. The left wing plate 23 and the right wing plate 21 are respectively fixedly connected to one end of the web 22, and the left wing plate 23 and the right wing plate 21 are connected to each other. The included angles of the web 22 are all 90°, the horizontal measuring instrument 1 is fixedly connected to the left wing plate 23, and the vertical measuring instrument 3 is fixedly connected to the web 22.

[0029] This structure is simple in structure and easy to manufacture. In this structure, the 90° included angle between the left wing plate 23 and the web 22 makes the installation angle requirements of the horizontal measuring instrument 1 and the vertical measuring instrument 3 easy to achieve.

[0030] Both the web 22 and the left wing plate 23 are provided ...

Abstract

The invention discloses a natural gas compressor piston rod runout measurement device. The device comprises a compressor control system and further comprises a horizontal measuring apparatus, a measurement installation frame, a vertical measuring apparatus, two data transmission cables and a middle body cover plate, wherein the measurement installation frame is fixedly connected to the middle body cover plate, both the horizontal measuring apparatus and the vertical measuring apparatus are fixedly connected to the measurement installation frame, the horizontal measuring apparatus is axially located in the horizontal direction, the vertical measuring apparatus is axially located in the vertical direction, the horizontal measuring apparatus is connected with the compressor control system through one data transmission cable, and the vertical measuring apparatus is connected with the compressor control system through the other data transmission cable. Natural gas compressor piston rod runout online monitoring is achieved, the runout value of the piston rod can be conveniently obtained in the overall operation process of a compressor, then, changes of the operation working conditions of the piston rod of the compressor can be embodied timely, monitoring of the performance of the compressor is facilitated, and controlling of the equipment failure of the compressor is facilitated.

Description

Technical field [0001] The invention relates to the field of natural gas compressor working condition measuring appliances, in particular to a natural gas compressor piston rod bounce measurement device. Background technique [0002] In natural gas compressors, one of the main reasons for the fracture of the crosshead and the piston rod is that the cylinder concentricity and the slideway concentricity are out of tolerance, and the most intuitive parameter reflecting the difference between the cylinder concentricity and the slideway concentricity is the beating value of the piston rod. Timely measurement of the difference in the runout of the piston rod is an important means to recognize the working status of the compressor. [0003] The existing measuring method of piston rod runout value is as follows: when the compressor is running, remove the compressor's middle body cover (cross head cover), and install the dial indicator on the frame near the compressor stuffing box assembly. ...
