Abstract:
1. A pressure-resistant explosion-proof connector that connects external equipment to a sealed space of a stator portion hermetically sealed by a can in contact with a handled fluid, an end bell, and an outer cylinder of a canned motor pump, comprising: a connection cylinder having a through hole extending from the sealed space toward the external equipment; a cylindrical body mounted to the through hole of the connection cylinder to form a gap and a depth of an explosion-proof gap; and a base joint that connects the connection cylinder to the sealed space, wherein one end of the connection cylinder is connected to the canned motor pump through the base joint connected to the sealed space, and an other end of the connection cylinder is connected to the external equipment through a joint connected to the external equipment, and the connection cylinder having the through hole has a structure to resist an inner pressure generated by a leaking handled fluid or gas by receiving the cylindrical body from a side of the connection cylinder connected to the canned motor pump.
