Abstract
The utility model discloses an explosion-proof motor pressure releasing apparatus which relates to the technical field of an explosion-proof motor for a submersible pump. The device is invented with the object of automatically releasing pressure when the internal parts of the motor break down under high pressure gas, so that further damage of the motor is avoided. The technical solutions are as follows. A lower bearing cavity of the motor is provided with a pressure releasing channel. The pressure releasing channel is provided with an explosion-proof sleeve and an explosion-proof post at the communicating part with a motor cavity. The pressure releasing channel has two parts which communicate with the outside. One part is provided with a gas releasing valve and the other part is provided with a pressure releasing valve. The high pressure gas passes along the pressure releasing channel to the pressure releasing valve before finally being exhausted safely to the outside. The overall apparatus of the utility model is arranged in the internal part of the lower bearing cavity and has a rather compact structure. The apparatus solves the explosion problems of a motor and prolongs the service lifetime of a product and improves the use safety as well.
Description
Affiliated technical field
The utility model relates to mechanical immersible pump field, relates in particular to immersible pump fire-proof motor device.
Background technology
At present, existing immersible pump fire-proof motor is to be made up of motor upper cover, motor casing, motor lower cover, rotor, upper bearing (metal) shell, upper bearing (metal), lower bearing shell, lower bearing, capsul, sealing ring.Motor internal is by sealing ring water-tight, form a confined space, explosion-proof ability depends on motor housing intensity, once damaging, burns by motor overload winding wire bag, producing gas cannot discharge, pressure piling exceedes motor housing strength degree, and motor demolition accident easily occurs, and user's property safety, personal safety are impacted.
Summary of the invention
(1) object showing
The utility model has overcome shortcoming of the prior art, and a kind of fire-proof motor pressure relief device is provided, in the time that motor breaks down generation pressure, releasing pressure automatically, prevent motor damage, can solve motor self Blow-up Problems, thereby improved product useful life and safety in utilization.
(2) technical scheme
The utility model solves the technical scheme that its technical problem adopts: a kind of fire-proof motor pressure relief device, it comprises: upper bearing (metal) body (1) is connected in motor casing (3) upper end, by sealing ring A (8) sealing, stator line bag (2) is installed on motor casing (3) inside, lower bearing body (10) is connected in motor casing (3) lower end, by sealing ring B (9) sealing.Lower bearing body has bearing chamber, accumulator, pressure release passage in (10), and pressure release passage connects motor cavity, bearing chamber and exterior.Pressure release passage is equiped with esplosion isolating cover (5) and flame proof post (4) with the motor cavity place of communicating, esplosion isolating cover (5) and flame proof post (4) flame that can gap goes out, in the time occurring that motor abnormality stator line bag (2) damages burning, motor casing (3) internal high pressure gas enters pressure release passage by esplosion isolating cover (5) and flame proof post (4) gap, pressure release passage and exterior have two places, one place is equiped with vent valve (6), vent valve (6) can be opened and discharge inner hectic fever gas after the normal use of motor, avoid pressure piling phenomenon, one place is equiped with relief valve (7), gases at high pressure are discharged to outside along pressure release passage by relief valve (7) safety, effectively discharge motor internal pressure.Whole device is placed in lower bearing body (10) inside, and compact conformation, had both facilitated dismounting, had improved again safety in utilization.
(3) beneficial effect
The beneficial effects of the utility model are, this device is a kind of fire-proof motor pressure relief device, by offering at lower bearing body, esplosion isolating cover, flame proof post and relief valve are installed, effectively ensure motor safety use, when motor breaks down generation gases at high pressure because of a variety of causes inside, this device discharges rapidly internal gas, has prevented that motor from further damaging, this device had both improved operating efficiency, had improved again safety in utilization.
