Abstract
The invention relates to a borehole shaft driven pump. The scheme that a vertical three-phase asynchronous motor is used for replacing a motor dedicated for a long shaft pump is adopted; a thrust device is arranged between the motor and a pump base for bearing the weight of a pump rotation component and axial force generated when the pump rotation component is operated; the thrust device comprises parts, such as a thrust bearing, a cooling device, a backstop and the like. According to the technical scheme disclosed by the invention, the vertical three-phase asynchronous motor and an explosion-proof vertical motor which can not bear the axial force can be selected so as to widen the application range of the borehole shaft driven pump and enlarge the operation performance range of the borehole shaft driven pump. Higher power, bigger flow and higher lift can be provided, and therefore the borehole shaft driven pump has a wider power range and more application ranges, thereby being favorable for the borehole shaft driven pump to develop to the large-scale multiple ranges.
Description
Technical field
The invention belongs to hydraulic machinery technical field, be specifically related to a kind of borehole shaft drivenpump.
Background technique
Borehole shaft drivenpump, as a time-honored pump type, has obtained application in many occasions.In recent years, along with the development of pump industry technology, borehole shaft drivenpump has also obtained using widely.But along with the raising of borehole shaft drivenpump performance parameter, flow is increasing, and lift is more and more higher, traditional borehole shaft drivenpump structural type exposes the place of some wretched insufficiencies.
The normally such structural type of traditional borehole shaft drivenpump as shown in Figure 3, mainly comprises four parts: be respectively borehole shaft drivenpump motor special 14, pump seat parts 2, lifting pipe parts 3, workpiece 4.As can be seen from Figure 3 the axial force, producing when pump operation and the weight of pump rotary component will be born by borehole shaft drivenpump motor special.The axial force producing when water pump operation is relevant with lift of pump, and along with increasing of lift, the axial force producing when pump operation increases.And along with the raising of performance parameter, the weight of pump is also in continuous increase.The pulling force that these factors cause borehole shaft drivenpump motor special to bear is increasing, and the pressure that namely thrust bearing bears is increasing, and bearing heating amount is increasing.Borehole shaft drivenpump motor special is because the reason of structure and bearing cannot be born larger axial force, and borehole shaft drivenpump motor special (YLB type) maximum common on domestic market is only accomplished 400kw.Seriously restrict the large scale development of borehole shaft drivenpump.Current domestic borehole shaft drivenpump motor special is not made explosion-proof type in addition, makes it can not be used for the fields such as colliery, petroleum gas, petrochemical industry and chemical industry yet, has limited the Applicable scope of borehole shaft drivenpump.The present invention can solve above two large defects.
Summary of the invention
For solving the problems of the technologies described above and defect, the invention provides a kind of borehole shaft drivenpump, it selects vertical threephase asynchronous to substitute the scheme of borehole shaft drivenpump motor special, make long-shaft pump can use more powerful motor, and can select explosion-proof electric machine, widen the using scope of borehole shaft drivenpump, be conducive to extensively promoting the use and large scale development of borehole shaft drivenpump.
Technological scheme: borehole shaft drivenpump of the present invention, between motor and pump seat, thrust device is set, be used for the axial force that the weight of bearing pump rotatable parts and when operation produce, thrust device is containing several large component such as thrust bearing, cooling unit, backstops.
Specifically, a kind of borehole shaft drivenpump of the present invention, it comprises common vertical threephase asynchronous, pump seat parts, lifting pipe parts, workpiece and thrust device, wherein said common vertical threephase asynchronous is contained in thrust device top, described thrust device is contained in described pump seat parts top, described lifting pipe parts are arranged on described pump seat parts bottom, described workpiece is arranged on lifting pipe parts bottom, it is characterized in that, the motor shaft of described common vertical threephase asynchronous and motor coupler are by key transmission, motor coupler and hollow shaft are connected to form entirety by bolt, upper end transmission shaft is threaded with adjusting nut, when Installation and Debugging, rotating nut is adjusted to suitable position, make to produce between impeller and pump case suitable axial clearance, then be bolted on the appropriate location of hollow shaft, upper end transmission shaft is suspended in hollow shaft by adjusting nut, non-return pin is arranged in the pin-and-hole of hollow shaft, pin-and-hole is evenly distributed on hollow shaft around the axis hole of hollow shaft, selling the aerial heart and hollow shaft, to cross axis hole center parallel, bearing cap upper surface have multiple tracks around center equally distributed groove, with hollow shaft, non-return pin composition backstop.
Compared with prior art, the present invention has the following advantages:
The present invention frees backstop, thrust bearing, cooling unit from motor.
1. non-return pin is housed on hollow shaft, and bearing cap Shang Youji road is uniformly distributed the non-return groove on it, can prevent motor reversal.
2. the axial force producing when borehole shaft drivenpump moves passes to transmission shaft by impeller shaft, transmission shaft is delivered to upper end transmission shaft, upper end transmission shaft acts on hollow shaft, thrust bearing (ball bearing) supports hollow shaft, the thrust of thrust bearing is born by bearing support, the pressure-acting that pump seat passes over bearing support is on pedestal, and so axial force is balanced, and motor does not bear axial force.
3. external the depending alone of thrust bearing air-cooledly can not meet heat radiation and require, and especially for bearing large axial force when, the type of cooling of thrust bearing of the present invention is water-cooled.When pump operation, from the water intaking of pump seat water outlet top, not needing provides cooling water in addition, cost-saving.WATER AS FLOW MEDIUM is delivered into bearing support through conduit pipe, in bearing support, there are two cavity weave ins, first oil pocket, the oil lubrication thrust bearing in oil pocket the heat that thrust bearing is produced are taken away, and another one cavity is exactly water channel, water channel in conduit pipe and bearing support is connected, cold water intaking is taken away the heat in lubricant oil during by water channel, and in order better to take away heat, oil pocket and water channel are weave ins, area of contact is larger, and heat radiation is better.This is just for selecting larger thrust bearing that condition is provided.
The present invention can allow motor select can not bear vertical threephase asynchronous and the explosion-proof type vertical machine of axial force.Widen the utilization field of borehole shaft drivenpump, expand its ride quality scope, can provide that the larger flow of high power is more high-lift, borehole shaft drivenpump uses vertical threephase asynchronous (containing explosion-proof type) to replace borehole shaft drivenpump motor special, make its power range wider, utilization field is more, is conducive to borehole shaft drivenpump to the multi-field development of maximizing.
