What is an explosion-proof compressor?

The flameproof and explosion-proof compressor is a piston-type equipment specially developed for the pressurization of hazardous gas. The electrical and moving parts of the whole machine are all designed according to the explosion-proof standard of GB3836, and are used for the pressurized transportation of combustible media such as methane, propane and vinyl chloride in petrochemical industry, oil and gas exploitation and hazardous waste treatment.

Core special requirements include:

The explosion-proof grade of the whole machine is up to standard: Ex d IIC T4/T6 explosion-proof motor, explosion-proof control cabinet and explosion-proof pressure sensor are standard to isolate the spark ignition mixture;

Spark-free compression cavity: the piston and valve plate are made of copper alloy with low friction to avoid open flame caused by metal collision and friction;

Dielectric replacement protection: supporting nitrogen pre-purging pipeline to replace the air inside the cavity before starting, so as to eliminate the explosion hazard of combustible gas mixture;

Real-time monitoring of leakage: the fuselage is equipped with combustible gas concentration detection probe, and the micro-leakage of medium will be immediately alarmed by sound and light and shut down by interlocking;

Electrostatic elimination system: the whole machine is grounded with all metal equipotential, and the pipeline uses conductive flange to prevent electrostatic accumulation and detonation medium.

Summary: This model is just needed for chemical explosion-proof working conditions, and the safety protection system is perfect; The structure of the whole machine is complex, and the cost of procurement and maintenance is high, so it is only allowed to be used in hazardous workshops with explosion-proof requirements.
