Product Introduction

1. Plunger Pump

1.1 Structural

Electric reinjection pump skid, Mainly composed of frequency control asynchronous motor, Frequency conversion control system, Pressure monitoring system, Three-cylinder plunger pump, Coupling, Power end lubrication system, Packing lubrication system, Displacement monitoring system.

1.2 Working principle

The triplex plunger pump is connected with the AC variable frequency motor through the universal joint coupling, and converts the rotational energy of the AC variable frequency motor into the reciprocating motion of the plunger.

1.3 Electric drive pump features

a) The electric drive pump is controlled by frequency converter. The inverter has complete protection functions. It can realize over-voltage, over-current, low-voltage, phase loss, over-load, short-circuit and other faults. It can be automatically converted to power frequency operation to ensure the normal operation of the plunger pump.

b) The frequency converter has a communication function, which can realize remote concentration and facilitate the detection of equipment operation.

c) Frequency conversion starts to reduce the impact on the power grid, in line with the needs of the site.

d) The whole structure is simple and compact, and the floor space is small, which is easy to install and transfer.

e) It has no exhaust gas has excellent environmental protection characteristics.
