Abstract

The utility model relates to a gas-liquid mixed transportation single-screw pump group provided with a forced lubrication protection system. The gas-liquid mixed transportation single-screw pump group comprises a mixed transportation single-screw pump mounted on a base, and is characterized in that a fluid infusion pump group capable of pouring pumping media or clear water into the mixed transportation single-screw pump is mounted on one side of the mixed transportation single-screw pump on the base, the fluid infusion pump group comprises a fluid infusion pump, a fluid storage tank, a motor, a ball valve and a pipeline, the fluid outlet of the fluid infusion pump is communicated with a pump body close to the stator end of the mixed transportation single-screw pump through the ball valve and the pipeline, and the fluid inlet of the fluid infusion is communicated with the fluid storage tank through the ball valve and the pipeline. According to the utility model, the gas-liquid mixed transportation single-screw pump group has the advantages that by the adoption of the fluid infusion pump group to pump up a small volume of media or clear water into the stator and the rotor of the mixed transportation single-screw pump, fluid is guaranteed to exist between the stator and the rotor of the mixed transportation single-screw pump, so that the fluid can protect the stator and the rotor, the dry friction between the stator and the rotor of the mixed transportation single-screw pump can be prevented, and the service life of the mixed transportation single-screw pump can be greatly prolonged.

Description

There is the gas-liquid delivery helical rotor pump group of pressure lubrication protective system
Technical field
The utility model belongs to volume type single screw pump field, particularly relates to a kind of gas-liquid delivery helical rotor pump group with pressure lubrication protective system that is applicable to crude oil exploitation.
Background technique
Helical rotor pump is a kind of positive displacement pump, has been widely used at present each industrial fields such as oil, chemical industry, sewage treatment and boats and ships.At oil, chemical field, particularly crude oil exploration industry, in order to improve crude output, to reduce production costs, the application of oil-gas mixed delivery pump (multiphase pump) more and more comes many, and it i.e. energy-conservation, consumption reduction, can improve again crude output.Described oil and gas multiphase flow is exactly that the multiphase mixtures such as the crude oil by oil well output, water, rock gas, sand and paraffin are concentrated on to the conveying on same pipeline.The pumping element of traditional helical rotor pump mainly forms by the screw rod as rotor with as the pump block of stator, and rotor is helical metal bar, and stator is with special process pressure injection bonding firmly rubber sleeve on inner wall of metal tube.Because the material of the stator of helical rotor pump is to adopt elastic caoutchouc to make, and be assembled into interference fit between rotor and stator, in the using process of oil-gas mixed delivery pump, in crude oil, contain a large amount of gas and impurity, now between rotor and stator, there is dry friction, not only rotor and stator are produced to heavy wear, also will cause very large infringement to helical rotor pump simultaneously, and then shorten Services Life of Single Screw Pump.
Summary of the invention
The utility model for solve the technical problem existing in known technology provide a kind of simple in structure, can in mixed defeated helical rotor pump, inject pumped medium or clear water; it is played a protective role, prevent the gas-liquid delivery helical rotor pump group with pressure lubrication protective system that dry friction occurs and can extend its working life between mixed defeated helical rotor pump rotor and stator.
The technological scheme that the utility model is taked for the technical problem existing in solution known technology is:
There is the gas-liquid delivery helical rotor pump group of pressure lubrication protective system; comprise: be arranged on the mixed defeated helical rotor pump on base; described base is positioned in a side of mixed defeated helical rotor pump the fluid infusion pump group that can inject to mixed defeated helical rotor pump pumped medium or clear water is housed; described fluid infusion pump group comprises fluid infusion pump, liquid tank, motor, ball valve and pipeline; described fluid infusion pump liquid outlet is communicated with the pump housing of close mixed defeated Stator of Single Progressive Cavity Pump end by ball valve and pipeline, and described fluid infusion pump liquid entering hole is communicated with liquid tank by ball valve and pipeline.
The utility model can also adopt following technological scheme:
Described ball valve adopts motorized adjustment ball valve, and described motorized adjustment ball valve is electrically connected with electric control cubicle.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, outside the pump housing of mixed defeated helical rotor pump, in a side, pressure lubrication protective system fluid infusion pump is installed, start before mixed defeated helical rotor pump, first open ball valve, the fluid infusion pump of the mixed defeated Stator of Single Progressive Cavity Pump of starting protection, pass through control system, to the mixed stator of defeated helical rotor pump and medium or the clear water of rotor pumping small flow, between the rotor of the mixed defeated helical rotor pump of assurance and stator, there is all the time liquid to exist, it is played a protective role, and can prevent from, between mixed defeated helical rotor pump rotor and stator, dry friction occurs, and then can significantly extend mixed defeated Services Life of Single Screw Pump.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: 1, mixed defeated helical rotor pump; 2, fluid infusion pump; 3, ball valve; 4, motor; 5, pipeline; 6, base; 7, liquid tank.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, there is the gas-liquid delivery helical rotor pump group of pressure lubrication protective system, comprise: be arranged on the mixed defeated helical rotor pump 1 on base 6, described base is positioned in a side of mixed defeated helical rotor pump the fluid infusion pump group that can inject to mixed defeated helical rotor pump pumped medium or clear water is housed, described fluid infusion pump group comprises fluid infusion pump 2, liquid tank 7, motor 4, ball valve and pipeline 5, the pump housing of described mixed defeated helical rotor pump 1 is provided with the flange that connects fluid infusion pump 2, described fluid infusion pump liquid outlet passes through ball valve, pipeline and fluid infusion pump interface flange are communicated with the pump housing of close mixed defeated Stator of Single Progressive Cavity Pump end, described fluid infusion pump liquid entering hole is communicated with liquid tank 7 by ball valve and pipeline.
In the present embodiment, described ball valve 3 adopts motorized adjustment ball valve, and described motorized adjustment ball valve is electrically connected with electric control cubicle.
Working principle of the present utility model is:
The motor 4 of the fluid infusion pump group of the mixed defeated Stator of Single Progressive Cavity Pump of starting protection; and make fluid infusion pump 2 inject pumping liquid or clear water by motorized adjustment ball valve and pipeline 5 to the stator of mixed defeated helical rotor pump 1 by control system; and then stator and the sealing of mixed defeated helical rotor pump are played a protective role, extend the working life of mixed defeated helical rotor pump.This pressure lubrication protective system also can, by automatically controlled, realize the automation of pumping liquid or clear water.
