Abstract
The utility model discloses a high-lift submersible pump. An anti-thrust mechanism is arranged between a water pump and a motor and comprises a central shaft, an anti-thrust unit and a connecting chamber, the anti-thrust unit is connected with the water pump, the connecting chamber is connected with the motor, the anti-thrust unit comprises an anti-thrust bearing, a thrust tray and a connecting case. The number of the anti-thrust units can be increased according to the axial force. A locating sleeve is arranged between the thrust trays of adjacent upper and lower anti-thrust units and has the effect of positioning the thrust tray and the anti-thrust bearing. According to the utility model, the axial force produced during the operation of the submersible pump is born by two or more anti-thrust bearings and thrust trays in place of one anti-thrust bearing and one thrust tray located at the lower part of the motor, thus the axial force to the anti-thrust bearing of the motor is reduced, a rotor of the motor is not easy to deform, the anti-thrust bearing and the thrust tray are not easy to be worn out, thereby improving the service life of the submersible pump.
Description
Technical field:
The utility model relates to submersible pump, relates in particular to high-lift submersible pump.
Background technique:
Submersible pump is made up of water pump and motor, the axial force that the thrust bearing of motor lower portion and thrust disc produce when being used for overcoming machine operation.Since drawdown, the weather arid, and high-lift submersible pump market demand obviously increases.Along with increasing of pump head, the downward axial force that water pump produces at work also correspondingly increases, and it is bigger that this just requires motor thrust bearing and thrust disc to bear the ability of axial force.Produce in the design, generally start with from the material and the performance that improve thrust bearing and thrust disc, but from reprocessing the abrasion condition of pump, the wearing and tearing that changed the thrust bearing of material and thrust disc are still very serious, even use month thrust bearing and thrust disc just to grind away, the simple material that changes, wear resistance still can not reach expection.
The model utility content:
The purpose of this utility model is to provide a kind of high-lift submersible pump that can overcome the motor axial force.
High-lift submersible pump of the present utility model comprises water pump, motor, is provided with thrust mechanism between water pump and motor, and thrust mechanism comprises axis, thrust unit, connects the chamber; Thrust unit and water pump link, and connect chamber and motor and link; The thrust unit with connect the chamber upper flange and connect; The thrust unit comprises thrust bearing, thrust disc, connection shell, and thrust bearing, thrust disc are located at and connect in the shell; The upper and lower end of axis links with water pump spindle and motor shaft respectively.
Thrust mechanism comprises two or more thrusts unit, and each thrust unit is upper and lower to be connected successively.
Be provided with setting sleeve between the thrust disc of upper and lower adjacent two thrust unit, described setting sleeve is enclosed within on the axis.
All be provided with seal arrangement in the thrust unit that connects the chamber and link with water pump.
Seal arrangement is an outside framework oil seal.
High-lift submersible pump of the present utility model on the basis of existing technology, has increased thrust mechanism between water pump and motor, the axial force that thrust bearing in the thrust unit and thrust disc produce when being used for decomposing submersible pump work.According to the size of the required axial force that overcomes, can increase the quantity of thrust unit.Setting sleeve is located between the thrust disc of upper and lower adjacent thrust unit, and thrust disc and thrust bearing are played the effect of location.Thrust unit, upper end and the outside framework oil seal that connects in the chamber prevent that sewage and impurity from entering thrust mechanism, plays the effect of sealing.The utility model makes axial force that submersible pump when work produce be born to become by two or more thrust bearings and thrust disc by thrust bearing that was positioned at motor lower portion originally and thrust disc and bears, reduced the axial force that passes on the motor thrust bearing, rotor is difficult for deforming, thrust bearing and thrust disc are not easy to wear, thereby have improved the working life of submersible pump.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is a thrust mechanism part-structure schematic representation among Fig. 1.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the bottom of motor for submerged pump 1 has thrust bearing 2, thrust disc 3, yet, along with the raising of submersible pump lift, the downward axial force that produces during pump working also correspondingly increases, and thrust bearing 2, thrust disc 3 can not have been born the axial force that has increased fully, the result causes thrust bearing 2, thrust disc 3 serious wear, even use and just ground away less than one month, and then causing motor to sink, water pump can't be worked.Evidence even if change material, still can not address this problem well.
As shown in Figure 1 and Figure 2, submersible pump of the present utility model has increased thrust mechanism between water pump 4 and motor 1.Thrust mechanism comprises axis 5, thrust unit, connects chamber 6, and the thrust unit links by connecting section 13 and water pump 4, connects chamber 6 and is connected with motor 1; The thrust unit with connect chamber 6 upper and lower connections; The thrust unit comprises thrust bearing 7, thrust disc 8, connects shell 9, and thrust bearing 7, thrust disc 8 are located at and connect in the shell 9; The upper and lower end of axis 5 links with water pump spindle and motor shaft respectively by coupling.
According to the size of the required axial force that overcomes, can increase the quantity of thrust unit, each thrust unit is upper and lower to be connected successively.As having two thrust unit in the thrust mechanism among Fig. 1, thrust bearing 10, thrust disc 11, connection shell 12 are formed another thrust unit, two upper and lower linking in thrust unit.
11 of thrust disc 8, thrust discs at two upper and lower thrust unit that link are provided with setting sleeve 14, and setting sleeve is enclosed within on the axis 5.Setting sleeve is used for to every group of thrust bearing, thrust disc location.
In order to prevent to leak or silt enters, connecting of thrust unit be provided with seal arrangement outside framework oil seal 16 in the shell 9 in the top that connects chamber 6 and link with water pump.
