Product Description
Three-phase chemical explosion-proof D-type evaporator R404a cold room air cooler
Features of explosion-proof motors
(1) Meet the requirements of increased-safety explosion-proof motors, adopt a series of reliable measures to prevent sparks, arcs and dangerous high temperatures, and can safely operate in explosion-hazardous areas in Zone 2.
(2) Brushless excitation is adopted, with a rotating rectifier disk and a static excitation cabinet, the excitation control system is reliable; the forward polarity slip excitation is accurate, without impact; the excitation system has reliable out-of-step protection and strong re-stepping capability; reasonable circuit design , The discharge resistor does not generate heat during work; the excitation current has a wide adjustment range.
(3) Synchronous machine, AC exciter and rotating rectifier disc are coaxial. The rectifier disk is located between the main motor and the exciter or outside the bearing seat.
(4) The enclosure protection class is IP54.
(5) F grade insulation is adopted, and the temperature rise is assessed according to B grade.
(6) Change the traditional lower water cooling to upper water cooling, that is, the water cooler is placed on the top of the motor.
(7) An increased-safety moisture-proof heater is installed, which is fixed in the cover at the bottom of the motor, and is used for heating and moisture-proof when the machine is shut down.
(8) Choose high-quality raw materials, and leave a large margin for electrical and mechanical calculations, which can meet the temperature requirements of operational reliability and increased safety motors.
(9) Complete monitoring measures are installed; the main junction box is equipped with an increased-safety self-balancing current transformer for differential protection; the stator windings are embedded and spare platinum thermal resistance, the graduation number is Pt100; water leakage monitoring is set Monitor the leakage of the water cooler; on-site temperature display instrument and remote signal terminal are respectively installed on the sliding bearing at both ends.
Explosion-proof motor structure characteristics
Compared with ordinary motors, the structural characteristics of explosion-proof motors are mainly that the respective contact surfaces between the base and the end cover, junction box, and junction box bottom and cover are set as explosion-proof surfaces. There is no substantial difference between the explosion-proof surface and the mating surface of ordinary motors, but to achieve higher sealing requirements, the mating area is enlarged (for example, the stop is longer) and the mating accuracy is enhanced. In this part, measures such as applying sealant and adding rubber gaskets are adopted; in addition, its junction box and the inside of the casing must be tightly isolated, which is not very noticed by ordinary motors. In order to prevent the casing from exploding once the pressure formed by the "explosion" inside the motor, the material used in the base, end cover, junction box, etc. must be high in strength and large in thickness. And to carry out pressure test (generally a water pressure test) for these parts, they can be assembled and used only after they are qualified.

Classification of explosion-proof motors
1, according to the principle of the motor
can be divided into explosion-proof asynchronous motors, explosion-proof synchronous motors and explosion-proof DC motors.
2, according to the place of use
can be divided into explosion-proof motors used in coal mines and explosion-proof motors used in factories.
3. According to the principle of explosion protection
can be divided into flameproof motors, increased safety motors, positive pressure motors, non-sparking motors and dust explosion-proof motors.
4. Classified by supporting equipment
It can be divided into explosion-proof motors for coal mine conveyors, explosion-proof motors for coal mine winches, explosion-proof motors for rock loaders, explosion-proof motors for local fans in coal mines, explosion-proof motors for valves, loud explosion-proof motors for fans, explosion-proof motors for ships, explosion-proof motors for cranes and metallurgy The motor and the hydrogenation device are matched with an increased safety brushless excitation synchronous motor, etc. In addition, it can also be classified according to technical indicators such as rated voltage and efficiency, such as high-voltage explosion-proof motors, high-efficiency explosion-proof motors, high-slip explosion-proof motors, and high starting torque explosion-proof motors.
1. Explosion-proof motors are generally used in flammable and explosive occasions
2. The sealing of the explosion-proof motor junction box is better than that of ordinary motors
3. The minimum protection level of explosion-proof motors is IP55, while ordinary motors have IP23, IP44, IP54, IP55, and IP56, so it can be distinguished from the appearance.
4. Explosion-proof motor is a motor that can be used in flammable and explosive places, and it does not produce electric sparks during operation.
5. The flameproof explosion-proof motor has a flameproof structure. When an explosion occurs inside the motor, due to the protection of the flameproof structure, the electric spark will not escape from the outside of the motor shell, thereby avoiding the occurrence of secondary explosions.
6. Explosion-proof motors are mainly used in coal mines, petroleum and natural gas, petrochemical and chemical industries. In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.
7. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery.
