Description
Technical field
The utility model relates to flame-proof type submersible pump technical field, specifically a kind of mining flame-proof type submersible booster pump.
Background technique
Along with the development of mine cause, mining high-voltage pump is applied in the production draining in mine more and more in recent ten years.The mining high-voltage pump using under existing coal mine all adopts machine form under traditional upper pump; this kind of structure solved the in use heat dissipation problem of motor of mining high-voltage pump well; but because motor is positioned at the bottom of pump, during vertical installation, often there will be draining problem not to the utmost.Solution is to be equipped with booster pump below mining high-voltage pump.Traditional booster pump is all non-flame-proof type based on cost consideration, and along with the raising of colliery to safety requirement, one way relay pump can not meet the demand of Mine Safety in Production.One way relay pump, due to the simplicity of its structure, often there will be problems such as burning motor, stator cavity water inlet, has greatly shortened the working life of booster pump, and the efficiency of coal production is also greatly affected.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of mining flame-proof type submersible booster pump is provided.
The technical solution of the utility model realizes in the following manner, this mining flame-proof type submersible booster pump, its structure comprises motor, air guide sleeve and the pump housing, the periphery of motor is provided with air guide sleeve, on air guide sleeve, be provided with push rod, push rod is fixed on air guide sleeve and push rod end extend in air guide sleeve and fixes with motor apical grafting; Motor lower end is provided with water conservancy assembly, between motor and water conservancy assembly, is provided with grease chamber; Pump housing lower end is provided with trash rack; Between motor and water conservancy assembly, there is three seals, that is: outside framework oil seal, first mechanical seal and second mechanical seal, wherein, outside framework oil seal is arranged between grease chamber and rotating shaft; First mechanical seal is arranged between the rotating shaft and outside, grease chamber of lower end, grease chamber; Second mechanical seal is arranged on the grease chamber of rotating shaft and the joining portion between motor.
The quantity of push rod is provided with four, and the orthogonal footpath of circumference that four push rods are positioned at same plane upwards.
Motor adopts flame-proof type submersible motor.
The joining portion of the airframe components of motor is provided with flameproof joint.
The beneficial effect that the utility model compared with prior art produced is:
This mining flame-proof type submersible booster pump can fundamentally meet the demand of Safety of Coal Mine Production, can make again the performance of motor be greatly improved, and extends the working life of booster pump.
Motor outer installment air guide sleeve.The main cause that affects motor working life is heat dissipation problem, if can not in time dissipation of heat be gone out, just there will be the problems such as burn bearing.In the present invention, the design of air guide sleeve makes water that booster pump carries all by the outside process of motor, and the heat major part that motor produces in running can be sent in outside water environment by motor case, then is taken away by the outer high-velocity flow of motor case.This structure has thoroughly solved the heat dissipation problem of motor, has greatly improved the working life of bearing of motor.
On air guide sleeve, there are four push rods.Booster pump can produce vibration in running, and especially start-up course vibration is larger.Because motor top is unsettled, the vibration that water conservancy assembly produces is reflected to motor top and can produces several times of even amplifications of tens times.The design of four push rods makes air guide sleeve, water conservancy assembly and motor three form an integral body, has avoided infringement booster pump being caused due to vibration cause.
Between motor and water conservancy assembly, be provided with three seals.In the water that booster pump is carried, contain a large amount of silt particles and pulverized coal particle, these solid particles are very large to the damage of mechanical seal, can when very short, chien shih mechanical seal lose efficacy, and then cause water from entering motor, damage motor.In the present invention, at motor and water conservancy inter-module, be provided with three seals.Outside framework oil seal and first mechanical seal are between grease chamber and external environment condition, and second mechanical seal is between motor interior and grease chamber.The effect of mechanical seal is waterproof, and the effect of outside framework oil seal is to stop molecule to enter grease chamber, and the two is reinforing function each other.Even grease chamber's water inlet in this case, motor still can work, and reliability strengthens.
Booster pump bottom is trash rack, can stop most foreign material (as leaf, weeds etc.) to enter water conservancy assembly, and relay has been pumped up to certain safety protection effect.
Motor is novel booster pump mining flame-proof type submersible motor.Between this kind of motor internal and external channel, there is flameproof joint, can meet the requirement of mine to safety; Simultaneously the particular design of motor interior can meet booster pump and even in the underwater environment of up to a hundred meters, moves at tens meters.
This mining flame-proof type submersible booster pump is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, has good value for applications.
