The invention discloses an explosion-proof improved system for a motor. The explosion-proof improved system comprises a motor sealing system, an electrical control system and a ventilation system, wherein a pressure transmitter is arranged between the motor sealing system and the electrical control system, one end of the ventilation system is connected with the motor sealing system, the other end of the ventilation system is connected with the electrical control system, the motor sealing system comprises a left side shaft seal system arranged on the left side of the motor, and a shutter, a right side cavity seal and a right side shaft seal which are arranged on the right side of the motor and are arranged on the right side of the motor, the shutter and the right side cavity seal are sequentially arranged from inside to outside, and the right side shaft seal is arranged on the outer side of a motor shaft. The explosion-proof improved system is composed of the motor sealing system, the electrical control system and the ventilation system. Through electrical control, the ventilation system is utilized to introduce air in a safe region into the motor body and the slip ring, and the lowest air pressure in the motor is ensured to be greater than 50Pa, so that the motor can meet the positive pressure operation requirement of the motor, and the GB3836 requirement is met.
Description
technical field [0001] The invention relates to the field of explosion-proof motors, in particular to an improved explosion-proof system for motors. Background technique [0002] TK series large-scale three-phase synchronous motors are specially matched for reciprocating compressors. They have the advantages of compact structure, high efficiency, low noise, and small vibration. They are widely used in refrigeration and fertilizer industries; their structural features are open structure, self-cooling , Without a cooler, the protection level is lower. Because most of its operating environments belong to the explosion-proof gas environment zone 2, according to the relevant national safety production regulations and safety evaluation requirements, this type of high-voltage motor must use explosion-proof motors, so it is necessary to carry out positive pressure explosion-proof transformation of TK series motors, especially in the chemical fertilizer industry. It must be done, an...
