The explosion-proof hydraulic oil filter is suitable for the oil filter used in the inflammable and explosive environment of power plant, etc. It can filter and deal with all kinds of turbine oil, refrigerated oil, hydraulic oil, lubricating oil, etc., and can be reused for regeneration and purification. What are explosion - proof oil filter belong to explosion - proof? Explosion-proof oil filter mainly refers to the electrical explosion-proof, generally only the contactor in the start will produce electric arc sparks, or bad wire contact may also produce electric sparks. Its heating system, electric control system, electric motor, solenoid valve and other electrical parts adopt explosion-proof type to meet the needs of various dangerous classes.
Difference between the explosion-proof hydraulic oil filter and ordinary motor:
(1) explosion-proof motor is generally used in inflammable and explosive occasions;
(2) the sealing of the junction box of the explosion-proof motor is better than that of the ordinary motor;
(3) the lowest explosion-proof motor protection grade is IP55. But there are IP44, IP54, and general motors are IP23, IP44, IP54 or IP55, IP56 range, it is suitable for excluding inflammable, explosive, corrosive gas and cleaner, and is used to drive all kinds of machinery and equipment without special requirements, such as machine tool, pump, fan, compressor, transport machinery, etc., it can tell from the appearance.
1. According to the type of motor, it can be divided into explosion-proof asynchronous motor, explosion-proof synchronous motor and explosion-proof dc motor.
2. It can be divided into explosion-proof motor for underground coal mine and explosion-proof motor for factory according to the place of use.
3. According to the explosion-proof principle, it can be divided into flameproof motor, safety increasing motor, positive pressure motor, sparkless motor and dust explosion-proof motor, etc
The explosion-proof electric control box is welded and welded by automatic protective gas. After welding, the surface is processed by special polishing process. The appearance is beautiful and the surface of the stainless steel is bright.
Applicable range of explosion-proof electric control box:
1. Dangerous gas sites in zone 1 and 2;
2. A and B Ⅱ Ⅱ, Ⅱ C T1 - T5 series of explosive gas or steam environment;
3. Indoor and outdoor (IP54, IP65* must be submitted when ordering).
Explosion-proof electric heater is a kind of energy consumption into heat energy to heat the material to be heated. Work in cryogenic fluid through the pipe under the action of pressure into the input port, along the electric heating container within specific in hot runner, the path of the design with the principle of fluid thermodynamics, take away the heat energy produced by electric heating element work, make the heating medium temperature, electric heater export process requirements of the high temperature medium. The internal control system of the electric heater automatically adjusts the output power of the electric heater according to the temperature sensor signal at the outlet to make the medium temperature at the outlet even. When the heating element is overheated, the independent overheat protection device of the heating element will cut off the heating power immediately to avoid the coking, deterioration and carbonization caused by the overheated heating material, which will lead to the burning out of the heating element in severe cases, thus effectively extending the service life of the electric heater.
