A kind of straight drive low speed plunger type water injection pump system
Technical field
The water injecting pump that the utility model is related to be used during a kind of oil exploitation, more particularly, to a kind of straight drive low speed column
Plug water filling pumping system, belongs to oil development field of mechanical technique.
Background technology
Water filling is to improve one of the most effective measure of rate of oil production and oil field ultimate recovery, is applied most in oil field development
Universal technology.With the application of waterflooding extraction technology, water injection equipment be also rapidly developed with it is perfect, have output pressure high
Multicylinder plunger formula water injecting pump be used widely.Existing piston reciprocating type water injection pump uses common variable-frequency motor, using skin
V belt translation deceleration mechanism, that there are transmission efficiencies is low, operating noise is big, the deficiencies of needing to regularly replace belt, and with water injection rate
Increase considerably, water filling power consumption has accounted for the 33%-50% of oil field total electricity consumption, and operating cost is high, cannot meet oil field and open
Production is adopted to noise reduction, consumption reduction, energy-efficient demand.
Utility model content
In order to overcome, power consumption existing for existing plunger type water injection pump is big, efficiency is low, operating noise is big, needs to regularly replace
Belt, cannot meet deficiency of the oilfield exploitation production to noise reduction, consumption reduction, energy saving requirement, and the utility model offer one kind is directly driven low
Fast plunger type water injection pump system.
Technical solution adopted by the utility model to solve its technical problems is:A kind of straight drive low speed plunger type water injection pump system
System, including water injecting pump, pedestal, motor, water injecting pump be fixedly mounted on pedestal, the motor is permanent magnet direct driving motor, it is described forever
The motor shaft of magnetic direct driving motor is connect by shaft coupling with the main shaft of the water injecting pump, and the water injecting pump is driven to operate.
Damping device is installed, the damping device is Rubber shock-absorbing pad below the permanent magnet direct driving motor.
The utility model has the beneficial effects that cancel belt gear, and it is simple in structure using motor direct-drive, it passes
Efficiency of movement is high, reduces operating cost, meets oilfield exploitation production to noise reduction, consumption reduction, energy-efficient demand.

In figure:1. permanent magnet direct driving motor, 2. water injecting pumps, 3. pedestals, 4. damping devices.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples.But those skilled in the art should
Know, the present invention is not limited to listed specific implementation modes, as long as meeting the spirit of the present invention, should all be included in this
In the protection domain of invention.
Referring to attached drawing 1,2.A kind of straight drive low speed plunger type water injection pump system of the utility model, including permanent magnet direct driving motor 1,
Water injecting pump 2, pedestal 3, water injecting pump 2 are fixedly mounted on the base 3, and driving motor uses permanent magnet direct driving motor 1, the permanent magnet direct-drive
The motor shaft of motor 1 is connect by shaft coupling with the main shaft of the water injecting pump 2, and the water injecting pump 2 is driven to operate.
Damping device 4 is installed, the damping device 4 is beam, usual damping below the permanent magnet direct driving motor 1
Pad selects natural rubber material, can effectively reduce influence of the vibrations to motor.
A kind of straight drive low speed plunger type water injection pump system of the utility model, the motor-type that the permanent magnet direct driving motor 1 is selected
Number it is TZBQ-185/260, pump speed is less than 260rpm, in conjunction with operation monitoring system, cancels belt drive unit, has structure letter
The advantages that list, high transmission efficiency, low operating cost.
The permanent magnet direct driving motor 1 of the utility model is controlled by controller, and after energization, permanent magnet direct driving motor 1 drives water injecting pump 2
Main shaft rotation, realize water filling pumping system low speed operation.Since water injecting pump 2 will produce vibration in the process of running, by institute
Permanent magnet direct driving motor 1 is stated on damping device 4, to reduce vibration influence caused by motor.
It should be noted that above-described embodiment is exemplary rather than the limitation present invention, those skilled in the art will design very
Right of more alternate embodiments without departing from this patent.
