Description
Technical Field
The invention relates to the technical field of circulating pumps, in particular to a circulating pump wiring sealing structure.
Background
Coal-to-liquids (CTL) is a technology for producing oil products and petrochemical products from Coal by chemical processing, and includes two technical routes, namely direct Coal liquefaction and indirect Coal liquefaction. The coal gasification technology and the Fischer-Tropsch synthesis technology are adopted to produce petroleum and chemical products such as gasoline, kerosene, diesel oil, synthetic wax, ammonia, ethylene, propylene, alpha-olefin and the like. A circulating pump is needed in the indirect coal liquefaction process, and a pump and a motor of the coal-to-liquid circulating pump are integrated. The pump body and the motor are separated into two chambers which are arranged in the shell, a gap exists between the two chambers, a sealing device is not arranged, the pressure can be communicated, but the furnace water in the pump body and the cooling water in the motor chamber are of two different water qualities, and the two water qualities cannot be mixed. However, the power cord of the motor still needs to be connected out of the shell, so a junction box is arranged outside the shell, but the wire joints of the current furnace water pump junction box all adopt a soft connection mode, and the connection mode cannot apply too much pressure to the wire joints, so the sealing performance is poor, and the wire joints are easily damaged to a certain extent due to too much applied pressure.

Aiming at the problems in the related art, the invention provides a circulating pump wiring sealing structure, wherein a wiring terminal and a self-sealing lead-out wire joint are in a connected state no matter whether a bolt is screwed up or screwed down, good electrical connection can be ensured, the sealing performance of the self-sealing lead-out wire joint and a circulating pump shell is not influenced by the tightness degree of the bolt, and a good sealing effect can be always kept.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention provides a circulating pump wiring sealing structure which comprises an explosion-proof junction box and a self-sealing lead-out wire connector, the explosion-proof junction box is fixed on the shell of the circulating pump, the self-sealing lead-out wire joint is fixed on the shell of the circulating pump in the explosion-proof junction box after being led out from the motor, the contact part of the self-sealing lead-out wire joint and the shell of the circulating pump is sealed, two fixing seats are arranged at the middle position of the inner wall of the explosion-proof junction box, a pressure plate is arranged between the two fixing seats, the pressure plate is fixed on the fixing seats through two bolts, a through hole is arranged in the middle of the pressure plate, a binding post penetrates through the through hole, a contact groove is arranged in the middle of one end of the binding post, which faces the self-sealing outgoing line joint, the shape of the contact groove is the same as that of the front end of the self-sealing lead-out wire connector, the contact groove and the self-sealing lead-out wire connector are matched in size, and the depth of the contact groove meets the requirement that the front end of the self-sealing lead-out wire connector can realize certain displacement and still can keep good electric connection.
Furthermore, the through-hole of clamp plate is "protruding" font, and is greater than the opposite side diameter towards self sealss lead-out wire connector one side, terminal middle part section also is "protruding" font, and is greater than the other end diameter towards self sealss lead-out wire connector one end.
The invention has the beneficial effects that:
the terminal and the self-sealing lead-out wire connector are in a connected state no matter the bolt is screwed up or loosened, good electrical connection can be guaranteed, meanwhile, the pressure plate can limit the shaking of the terminal and keep the terminal stable, so that good electrical connection of the terminal and the terminal is guaranteed, in addition, the sealing performance of the self-sealing lead-out wire connector and the circulating pump shell is not influenced by the tightness degree of the bolt, and good sealing effect can be always kept.
