Abstract
The utility model provides a submersible electric pump with an axial thrust balancing function. The submersible electric pump with the axial thrust balancing function comprises a pump body and a transmission shaft installed in the pump body. The submersible electric pump with the axial thrust balancing function is characterized in that a set of thrust bearing device is additionally arranged, the thrust bearing device comprises a balancing seat, a thrust disc, a retainer, a plurality of block thrust bearings, a plurality of thrust bearing seats and a plurality of graphite thrust bearings, wherein the balancing seat is sleeved on the transmission shaft, the upper end face and the lower end face of the balancing seat are fixedly connected with the pump body, the thrust disc is installed in the balancing seat through a ball face, the retainer is fixed on the thrust disc, the block thrust bearings are connected into a whole through the retainer, the thrust bearing seats are installed on the transmission shaft through keys, each graphite thrust bearing is bound and fixed on one thrust bearing seat, and the lower end face of each graphite thrust bearing is buckled on one block thrust bearing. The thrust bearing device is additionally arranged, the axial thrust generated by high speed rotation of a water pump impeller is borne by the graphite thrust bearings, so that the bearing capacity of the thrust bearings on a motor is reduced, and therefore the service life of the motor is prolonged. The thrust bearing device can be widely applied to the submersible electric pump, especially a high-lift submersible electric pump.
Description
Technical field
The utility model provides a kind of Submerged Motor Pumps with balancing axial thrust function, belongs to the pump technology field.
Background technique
Water pump has axial force in the rotor effect in operation process, this power will spur whole rotor axial and move.Therefore must manage to eliminate or this axial force of balance, can make the water pump proper functioning.The motor of Submerged Motor Pumps is positioned at the bottom of water pump, and the axial force that water pump produces is generally born by the thrust bearing of motor lower portion, but thrust bearing bears axial force certain limit is arranged.If the axial force of water pump is excessive, surpass the bearing capacity of motor thrust bearing, the motor thrust bearing will soon wear and tear, thereby damages motor.The method of balancing axial thrust is to open equalizing orifice and add the back choma at impeller at present, with the strength of minimizing thrust bearing, thus the working life of prolongation motor.
The model utility content
The purpose of this utility model just provide a kind of can overcome between above-mentioned defective, water pump and the motor can not influence each other, long service life.Particular content is as follows:
A kind of Submerged Motor Pumps with balancing axial thrust function, comprise the pump housing and be installed in the interior transmission shaft of the pump housing, it is characterized in that: set up a cover axial rolling bearing, comprise the balance seat, thrust disc, retainer, a plurality of piecemeal thrust bearings, thrust shaft block and graphite thrust bearing, wherein the balance cover for seat is contained on the transmission shaft, on, fixedly connected with the pump housing in the lower end surface, thrust disc is installed in the balance seat by sphere, retainer is fixed on the thrust disc, a plurality of piecemeal thrust bearings are connected as a single entity by retainer, thrust shaft block is installed on the transmission shaft by key, and the graphite thrust bearing is bonded and fixed on the thrust shaft block, and the lower end surface is fastened on the piecemeal thrust bearing.
The utility model compared with prior art, its advantage is: by setting up axial rolling bearing, water pump vane rotated at a high speed produce to such an extent that axial force is born by the graphite thrust bearing, thereby reduce that thrust bearing gets bearing capacity on the motor, thereby improve the working life of motor, can be widely used on Submerged Motor Pumps, the especially high-lift Submerged Motor Pumps.
