Abstract
The utility model relates to a pump with teflon coating. A pump body is provided with an inlet and an outlet which are orthogonal each other, impeller wheels are installed on the end part of a shaft, and the inner surface of the pump body, the impeller wheels and the surface of the shaft, which are also provided with the teflon coating. The utility model has the advantages of high-temperature resistance, low-temperature resistance, anticorrosion, prevention of sticking, antiscale, etc., and the utility model also has the advantages of stable operation and long service life, and is especially suitable for using in the severe environment of petroleum industry, etc.
Description
The utility model relates to a kind of pump, applicable to oil behavior water mixing oil transportation, multiple uses such as water filling.
At present, the pump that is adopted in the petroleum industry order, as water mixing pump, oil transfer pump, water injection pump etc., there is following problems, the high-and low-temperature resistance ability is because work under bad environment needs anticorrosion, antiseized, antiscale, the said goods fails effectively to solve this class problem, makes reduce greatly the working life of product.
The purpose of this utility model is to overcome the deficiency of above-mentioned known technology, thereby the pump of poly-tetrafluoro coating of the band of a kind of high-and low-temperature resistance, antiseized, antiscale is provided.
The purpose of this utility model realizes in the following way:
This pump is made up of the pump housing (1), bonnet (2), impeller (3), axle (4), elastic coupling flexible coupling (5) and bearing (ball) cover (6), wherein: the pump housing (1) has orthogonal import and export, have impeller (3) in the pump housing (1), impeller (3) links by pin is coaxial with axle (4), the axle (4) by Bearing Installation on bearing (ball) cover (6), the other end passes the pump housing (1) and connects elastic coupling flexible coupling (5), also has poly-tetrafluoro coating (7) on the pump housing (1) internal surface, impeller (3) and axle (4) surface.
The utility model compared with prior art has following advantage:
This pump has advantages such as high-and low-temperature resistance, anticorrosion, antiseized, antiscale, working stability, long service life.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model plan view.
Fig. 2 is a poly-tetrafluoro coating sectional view in the pump housing.
In the drawings: (1) pump housing; (2) bonnet; (3) impeller; (4) axle; (5) elastic coupling flexible coupling, (6) bearing (ball) cover, (7) gather the tetrafluoro coating.
During work, motor rotates by elastic coupling flexible coupling and axle (4) impeller, and impeller is discharged to outlet with centrifugal, and poly-tetrafluoro coating can be located at the interior flow passage part table of the pump housing and exist, and cladding material can be teflon.
Claims (1)
1, a kind of pump that has poly-tetrafluoro coating, form by the pump housing (1), bonnet (2), impeller (3), axle (4), elastic coupling flexible coupling (5) and bearing (ball) cover (6), it is characterized in that: the pump housing (1) has orthogonal import and export, have impeller (3) in the pump housing (1), impeller (3) links by pin is coaxial with axle (4), the axle (4) by Bearing Installation on bearing (ball) cover (6), the other end passes the pump housing (1) and connects elastic coupling flexible coupling (5), also has poly-tetrafluoro coating (7) on the pump housing (1) internal surface, impeller (3) and axle (4) surface.
