Abstract
The invention provides a vertical mining submersible pump with a water-leak-proof structure of binding post components. Generally, six binding post components are arranged in a wiring box of a mining submersible pump according to needs of explosion suppression, water drops between a sealing ring of an external cable and the cable drip in a cavity of the wiring box frequently, the water drops easily drip on the surface of a motor stator winding by passing through the matching face of the binding post components and the wiring box, and as a result, a motor is broken down and burned down. According to the vertical mining submersible pump, the matched upper plane of the binding post components and the wiring box is sealed by an O-shaped rubber seal ring. The vertical mining submersible pump has the advantages that the water drops can not easily drip on the surface of the motor stator winding even if few water drops drip in the cavity of the wiring box, and the overall operation service life of the vertical mining submersible pump is prolonged.
Description
Affiliated technical field
The present invention is a kind of vertical mining diving pump that adopts wiring terminal parts water leak preventing structure, and this pump is mainly used in middle-size and small-size hole, its inner supporting dry type asynchronous motor, and impeller, volute are in whole pump bottom, and integral pump structure can be in-built, also can be exterior.This mining diving pump has a terminal box, and 6 wiring terminals are housed in terminal box, and motor stator winding outlet is connected to wiring terminal lower end, and external cable is connected with wiring terminal upper end by connector cover.Belong to universal machine product manufacturing technology field.
Background technique
Vertical mining diving pump has the outstanding advantages such as structure, the construction investment of saving pumping plant of compact and portable, can significantly reduce draining cost, reduction of erection time is used in a large number in the internal drainage of middle-size and small-size hole, and particularly middle low power mining diving pump operation mean lifetime is about three months.The type pump entirety has flame proof requirement conventionally, and the sealing of external cable and connector cover adopts rubber seal, and external cable enters after terminal box cavity, is connected with wiring terminal upper end, and wiring terminal lower end is connected with motor electronic winding.Must flame proof between motor cavity and terminal box cavity.Because star triangle switches the needs of different voltages, wiring terminal parts are generally 6.
Because the sealing of external cable and connector cover adopts rubber seal, rubber seal is aging, artificially pull cable or the reason due to cable and cable sealing ring workmanship, between the seal ring and cable of external cable, between the seal ring of external cable and connector cover, often there is water droplet and leak and enter terminal box chamber, water droplet splashes into motor stator winding surface after very easily further coordinating plane with terminal box by wiring terminal parts, causes motor breakdown and the fault such as burn.
Summary of the invention
In order to extend the whole pump operation time, minimizing water droplet splashes into the possibility on motor stator winding surface by wiring terminal parts and terminal box fitting surface, and the present invention has adopted wiring terminal parts water leak preventing structure in vertical mining diving pump.Even if there is a small amount of water droplet to enter into from cable seal the upper plane that wiring terminal parts coordinate with terminal box; because the upper plane place coordinating with terminal box at wiring terminal parts is provided with " O " type rubber seal coil structures; thereby ensure that a small amount of water droplet still rests in terminal box cavity; enter into terminal box cavity so long as not a large amount of water; even if the insulation effect of whole pump declines to some extent; but avoid water droplet directly to arrive on dry type motor winding; pump can also move conventionally, and reliability and the working life of whole pump are increased.
The technical solution adopted for the present invention to solve the technical problems is:
" O " type rubber seal ring recess is set on wiring terminal parts, in the time of whole pump assembling, is pressed into O at " O " type rubber seal ring recess arranging " type rubber seal.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing 1 is the main sectional view that does not adopt vertical mining diving pump example of the present invention: 1. external cables in figure, 2. connector cover, 3. rubber seal, 4. terminal box, 5. terminal box cavity, 6. wiring terminal parts, 7. wiring terminal parts coordinate plane with terminal box, 8. upper bearing (metal), 9. staor winding, 10. motor cavity, 11. lower bearings, 12, mechanical seal, 13, impeller, 14, volute.
Accompanying drawing 2 is traditional wiring terminal parts and the partial enlarged drawing of terminal box cooperation place, can find out, coordinate plane 8 with terminal box if having water droplet fitting surface with rubber seal 3 peripheral from cable 1 or rubber seal 3 to enter wiring terminal parts with connector cover 2, water droplet is possible from the matching gap of wiring terminal parts 6 and terminal box 4, enter motor cavity 10, and may cause rapidly staor winding 9 to be subject to that water droplet infiltrates, motor is breakdown burns.
Accompanying drawing 3 is to adopt wiring terminal parts after the present invention and the partial enlarged drawing of terminal box cooperation place.
Embodiment
For a kind of vertical mining diving pump that adopts wiring terminal parts water leak preventing structure, on wiring terminal parts, process " O " type rubber seal ring recess, and the upper plane turning coordinating with wiring terminal parts in terminal box is worked into more than 6.3 precision.In the time of whole pump assembling, in " O " type rubber seal ring recess on wiring terminal parts, place O " type rubber seal.The vertical mining diving pump of this employing wiring terminal parts water leak preventing structure, do not increase too much cost, but reduced the breakdown and rate of fault of burning of motor.
Claims (1)
1. one kind adopts the vertical mining diving pump of wiring terminal parts water leak preventing structure, this mining diving pump has a terminal box, 6 wiring terminals are housed in terminal box, and motor stator winding outlet is connected to wiring terminal lower end, and external cable is connected with wiring terminal upper end by connector cover.The innovation of this pump is that upper plane utilization " O " the type rubber seal that wiring terminal parts are coordinated with terminal box seals.
