Problems solved by technology

[0003] However, the existing air compressor storage tanks are often not equipped with temperature monitoring and protection devices, which are difficult to meet the application requirements in coal mines.
Even if there are temperature monitoring and protection devices equipped with some air compressor air storage tanks, it is often difficult to automatically cut off the power supply, or it is difficult to achieve accurate monitoring and protection

Abstract

The invention belongs to the technical field of safety protection equipment, and relates to an air compressor air storage tank monitoring protection device and method.The monitoring protection device comprises a temperature probe (1) installed on an air compressor air storage tank (A) and a temperature itinerant detector (2) installed in a compressor room; the temperature probe (1) is connected with the temperature itinerant detector (2) through a cable (3), a normally-closed locking contact (4) of the temperature itinerant detector (2) is locked with an emergency stop loop of the air compressor, when the temperature detected by the temperature probe (1) reaches a set upper limit, the normally-closed locking contact (4) of the temperature itinerant detector (2) is disconnected, and when the temperature detected by the temperature probe (1) reaches the set upper limit, the normally-closed locking contact (4) of the temperature itinerant detector (2) is closed. And therefore, the air compressor stops working. The protection functions of overtemperature on-line monitoring, alarming and automatic shutdown of the air storage tank of the compressor are achieved.

Description

technical field [0001] The invention belongs to the technical field of safety protection equipment, and relates to a monitoring and protection device and method, in particular to an air compressor air storage tank monitoring and protection device and method. Background technique [0002] Air compressors are used in coal mines. When using an air compressor, there must be a matching air storage tank. Article 430 of the "Coal Mine Safety Regulations" stipulates that "the temperature in the gas storage tank should be kept below 120°C, and an over-temperature protection device should be installed to automatically cut off the power supply and give an alarm when the temperature is over-temperature." Therefore, in order to meet the requirements of the "Coal Mine Safety Regulations" and meet the safety requirements, it is necessary to equip the air compressor air storage tank with a temperature monitoring and protection device. [0003] However, the existing air compressor storage ...
