Self-adaptive adsorption type reciprocating compressor valve temperature sensor

Abstract

The invention relates to a reciprocating compressor valve temperature signal acquisition sensor, in particular to a temperature sensor with a self-adaptive adsorption structure. The sensor comprises an end face type platinum thermistor temperature probe, wherein the probe mainly consists of three parts: a temperature acquisition end face on the front section, a spring in the middle and a signal output structure at the rear end; and a magnetic base comprises the following parts: a magnetic base sheath, a sliding block, a wiring column, a plurality of magnets and a magnetic base shell. The magnetic base sheath, the wiring column and the magnets are arranged in sequence from top to bottom; the center of the bottom of the magnetic base is provided with a hole for arrangement of the sliding block, four magnets are arranged in the magnetic base and are distributed in the magnetic base and on the lower end face of the magnetic base, drilling and tapping is performed in the middle of the sliding block, the end face type platinum thermistor temperature probe is fixed in the sliding block through threads, and the lower end face of the temperature probe extends out of the magnetic base due to effects of the spring. The defects of the existing reciprocating compressor valve temperature sensor such as poor adaptability, limited adsorption capacity and large errors in acquisition can be overcome, and requirements of use in different environments on the site can be satisfied.

Description

technical field [0001] The invention relates to a temperature signal sensor for an air valve of a reciprocating compressor, which is a temperature sensor adopting an adaptive adsorption structure. Background technique [0002] The air valve of the reciprocating compressor includes a suction valve and an exhaust valve. The temperature difference between the two is large. Under normal working conditions, the temperature of the suction valve cover is stable at about 40°C, and the temperature of the exhaust valve cover is stable at about 100°C; After a fault occurs, such as leakage fault, valve plate fracture fault, the temperature of the valve cover of the gas valve will change significantly. According to the American Petroleum Institute API618 standard: "Unless otherwise specified and agreed, the maximum expected discharge temperature shall not exceed 150°C (300°F). This limit applies to all specified operating and loading conditions. The temperature rise is provided to the p...

Problems solved by technology

[0005] In order to conveniently and effectively solve the defects of low reliability, large measurement error and inconvenient installation and replacement of the existing on-line monitoring sensor for the gas valve temperature of the reciprocating compressor, the present invention considers the requirement that the valve cover of the gas valve of the reciprocating compressor cannot be drilled to damage the structure, and the design A structure that can be adaptively adsorbed on the valve cover of different surface structures and perform temperature collection

The invention can not only solve the disadvantages of the existing reciprocating compressor air valve temperature sensor, such as insufficient adaptability, limited adsorption capacity, and large acquisition error, but also meet the requirements of different environments on site, and improve the monitoring ability of the air valve temperature of the reciprocating compressor
