Abstract
The utility model relates to pumps for transporting liquid medium, in particular to a novel dry minitype electric submersible pump, which mainly comprises an electrical motor, a mechanical seal, an oil cavity, a water inflow segment, a pump body and an impeller assembly. The novel dry minitype electric submersible pump is characterized in that a pressure adjusting membrane and a pressure plate are arranged on the water inflow segment; one end on the periphery of the pressure adjusting membrane is connected with the water inflow segment, the other end is connected with the pressure plate, and pressure adjusting holes are arranged on the pressure plate. The pressure adjusting membrane is in the shape of a bowl one end of which is open, and the surface of the bottom of the bowl is an uneven surface. Owing to the structure of the utility model, the service life of the minitype electric submersible pumps is greatly prolonged, and the utility model has the advantages of reasonable structure, simple manufacture, no influence from diving depth, long service life, convenient operation and the like.
Description
Technical field
The utility model relates to the pump class of carrying liquid medium, specifically a kind of novel dry type small-sized diving electric pump.
Background technique
At present, the dry type small-sized diving electric pump that generally uses on the market mainly is made up of motor, mechanical seal, grease chamber, water inlet joint, the pump housing, impeller.The dry type motor links to each other with the water inlet joint, and the water inlet joint is connected with the pump housing, is provided with impeller in the pump housing, impeller is connected with motor shaft, its main feature is that pump is coaxial, and is simple in structure, easy for installation, slips into depth as shallow, influence working life, shortcoming such as is inconvenient to use but exist.The deficiency of above-mentioned this structure is: the electric pump degree of depth of diving beneath the water can not be goed deep into 5 meters (NBS), if be deeper than 5 meters, mechanical seal will be opened, and water will enter the motor the inside, and electric pump is burnt, and brings very big inconvenience to the user.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of rational in infrastructure, novel dry type small-sized diving electric pump of not slipped into degree of depth restriction, long service life is provided.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of novel dry type small-sized diving electric pump, it mainly is made up of motor, mechanical seal, grease chamber, water inlet joint, the pump housing, impeller, it is characterized in that into the water joint is provided with pressure regulator membrane and pressing plate, periphery one end of pressure regulator membrane is connected with the water inlet joint, the other end is connected with pressing plate, pressing plate is provided with regulator hole, in order to balanced seal chamber external and internal pressure, makes mechanical seal do not slipped into the influence of the degree of depth.
Pressure regulator membrane in the utility model is the bowl-type of an end opening, and bowl bottom is a male and fomale(M﹠F), is beneficial to bear more earth pressure.
The utility model makes the utility model not be subjected to the influence of diving depth owing to adopt said structure, greatly facilitates the user and uses the working life of having improved electric pump, has advantages such as rational in infrastructure, working service convenience, long service life.
