Abstract
A thrust bearing deep well submersible pump is mounted on the pump. It is characterized in that the thrust shaft sheet is arranged between the water pump and the motor; the deep well submersible pump with extremely high lift can be manufactured by the structure of a plurality of thrust discs and a plurality of dead axle seats.
Description
The present invention relates to a kind of pump and carry the thrust bearing deep well submerged pump.
Existing deep well submerged pump is in order to bear water pump forward (contrary water inlet direction) axial force, and the below of pump is provided with the positive axial thrust bearing of single-stage every crossing motor in its bottom.In order to bear oppositely (along the water inlet direction) axial force of water pump, be provided with reverse plain thrust bearing in the water inlet joint of pump, general radial sliding bearing with water inlet joint core is integrated shape such as type.The US3234886 U. S. Patent is provided with the reverse thrust bearing of free-standing single-stage at water inlet joint core: the water pump spindle lower end, on the coupling band of water pump and motor, by splined an independent thrust disc; On the thrust disc, water inlet joint core inner chamber end face is pressed embedding one thrust block, folder one wear-resisting dish between thrust disc and the thrust block.But these structures all can not be born the forward axial force of water pump.The positive axial thrust bearing basis of the single-stage of existing deep well submerged pump is that water pump is required, and but it is following every crossing motor configurations, not only can not bear bigger axial force; And the axial pressurized of when work motor rotor, diminish motor shaft and bearing.
The present invention is intended to create a kind of pump that can bear huge forward axial force and carries the thrust bearing deep well submerged pump.
Pump of the present invention carries the thrust bearing deep well submerged pump, is made up of the pump housing, multistage vertical centrifugal impeller, pump shaft, water inlet joint and check valve.Water inlet is saved screw and is linked to each other with the pump housing; Water intake is arranged on the periphery; The lower end is connected with motor; Inner chamber is equipped with thrust bearing.Thrust bearing in the water inlet joint is made of a plurality of thrust discs and a plurality of thrust block.Each thrust disc is above corresponding each thrust block.
Advantage of the present invention is two: 1, it is big to bear axial force; 2, directly bear the water pump axial force, make axially pressurized not of motor shaft.
Accompanying drawing shows that pump carries thrust bearing deep well submerged pump structure principle chart.
Pump carry thrust bearing deep well submerged pump (accompanying drawing) by the pump housing (1), multistage vertical centrifugal impeller, pump shaft (4) water inlet joint (2), pump carries thrust bearing and check valve is formed.Water inlet is saved screw and is linked to each other with the pump housing; Water intake is arranged on the periphery; The lower end is connected with motor; Inner chamber is equipped with multistage thrust bearing.Each thrust disc (3) utilizes screw thread or key to be contained in the pump shaft below.Each thrust block (5) utilizes fine thread to be fixed on in the water joint below corresponding each thrust disc.Adorn with wear-resisting dish (6) with sunk screw on each thrust block.Thrust disc and thrust block interleaved are arranged.Uniform several axial water ports and do mounting or dismounting and use on each thrust disc, the thrust block.The spacing of each thrust disc thrust surface equates that with the mill surface spacing that holds of the wear-resisting dish of each thrust block therefore dress back thrust bearings at different levels can balanced pressure-bearing.The forward axial force of the multistage deep well submerged pump of thrust bearing level data size and deciding.Because each thrust disc is contained in water pump spindle below, so the forward axial force during pump working acts directly on the thrust bearings at different levels.Water inlet joint inner chamber end face is made thrust surface, and adorns with wear-resisting dish, in order to bear reverse axial force with sunk screw.Under the most next thrust disc of thrust bearing, by screw thread on the pump shaft or keyed jointing coupling (7), this coupling links to each other with submersible electric motor (8).Be equipped with on the water pump spindle in the water inlet joint and get rid of abrasive cone (9) and the sealing of outside framework oil seal (10) sand control.The outer filter screen that is being screwed of water inlet joint.
Claims (2)
1, pump carries the thrust bearing deep well submerged pump, form by the pump housing (1), multistage vertical centrifugal impeller, pump shaft (4), water inlet joint (2) and check valve, water inlet is saved screw and is linked to each other with the pump housing, water intake is arranged on the periphery, the lower end is connected with motor, inner chamber is equipped with thrust bearing, and feature of the present invention is: the thrust bearing in the described water inlet joint is made of a plurality of thrust discs (3) and a plurality of thrust block (5), and each thrust disc is above corresponding each thrust block.
2, pump according to claim 1 carries the thrust bearing deep well submerged pump, it is characterized in that described each thrust disc utilizes screw thread or key to be contained in the pump shaft below, each thrust block utilizes fine thread to be fixed on in the water joint, adorn with wear-resisting dish (6) with sunk screw on each thrust block, thrust disc and thrust block interleaved are arranged, uniform several axial bores on each thrust disc, the thrust block, the spacing of each thrust disc thrust surface equates with the mill surface spacing that holds of the wear-resisting dish of each thrust block.
