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, obtains application in many occasions.In recent years, along with the development of pump industry technology, borehole shaft drivenpump have also been obtained and uses 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 structural type that borehole shaft drivenpump traditional is as shown in Figure 3 normally such, mainly comprises four parts: be borehole shaft drivenpump motor special 14, pump seat parts 2, lifting pipe parts 3, workpiece 4 respectively.As can be seen from Figure 3, the weight of the axial force produced during pump operation and pump rotary component will be born by borehole shaft drivenpump motor special.The axial force produced during water pump operation is relevant with lift of pump, and along with increasing of lift, the axial force produced during 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 namely the increasing pressure that bears of thrust bearing is large, and bearing heating amount is increasing.Borehole shaft drivenpump motor special is because the reason of structure and bearing, and cannot bear larger axial force, maximum of borehole shaft drivenpump motor special (YLB type) common on domestic market accomplishes 400kw.Seriously constrain the large scale development of borehole shaft drivenpump.Current domestic borehole shaft drivenpump motor special does not make explosion-proof type in addition, also makes it can not be used for the fields such as colliery, petroleum gas, petrochemical industry and chemical industry, limits 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, long-shaft pump is enable to use more powerful motor, and can explosion-proof electric machine be selected, 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, arranges thrust device, be used for bearing pump rotatable parts weight and run time the axial force that produces, thrust device is containing several large component such as thrust bearing, cooling unit, backstop.
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 section upper, 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, during Installation and Debugging, rotating nut adjusts to suitable position, make between impeller and pump case, to produce 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, sell the aerial heart and hollow shaft crosses axis hole center parallel, bearing cap upper surface have multiple tracks around center equally distributed groove, form backstop with hollow shaft, non-return pin.
Compared with prior art, the present invention has the following advantages:
The present invention makes backstop, thrust bearing, cooling unit free from motor.
1. hollow shaft is equipped with non-return pin, bearing cap Shang Youji road is uniformly distributed the non-return groove on it, can prevent motor reversal.
2. the axial force produced when borehole shaft drivenpump runs 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, pump seat acts on the pressure that bearing support passes on pedestal, and axial force like this is balanced, and motor does not bear axial force.
3. external the depending alone of thrust bearing air-cooledly can not meet cooling requirements, and especially for when bearing large axial force, the type of cooling of thrust bearing of the present invention is water-cooled.Fetch water above pump seat water outlet during pump operation, do not need to provide cooling water in addition, cost-saving.WATER AS FLOW MEDIUM is delivered into bearing support through conduit pipe, two cavity weave ins are had in bearing support, first oil pocket, the oil lubrication thrust bearing in oil pocket is also taken away the heat that thrust bearing produces, and another one cavity is exactly water channel, water channel in conduit pipe and bearing support is connected, cold water intaking is by during water channel taking away the heat in lubricant oil, and in order to better 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 to provide condition.
The present invention can allow motor select can not to 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, more large discharge is more high-lift can to provide more high power, 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 maximization.
