Reversing reciprocating screw pumping unit and usage method thereof

Abstract

The invention relates to a reversing reciprocating screw pumping unit and a usage method thereof. According to the technical scheme, a rack assembly is arranged on a base assembly, a reversing gear assembly is arranged in the rack assembly, the reversing gear assembly comprises a rolling body, a pin roll, a sliding sleeve and a reciprocating screw, wherein the reciprocating screw is connected with a motor reduction gear assembly, and the motor reduction gear assembly drives the reciprocating screw to rotate in the same direction continuously; the reciprocating screw is provided with spiral grooves; the sliding sleeve is movably connected with the reciprocating screw through the pin roll; the rolling body rolls in the spiral grooves of the reciprocating screw; power is transmitted between the sliding sleeve and the reciprocating screw through the rolling body and the pin roll; the sliding sleeve is fixedly connected with a weight box assembly. The reversing reciprocating screw pumping unit and the usage method thereof have the advantages that the reversing of a pumping unit is achieved by the adoption of a reciprocating screw sliding sleeve transmission pair, the structure is compact, and the mechanism is simple; the movement is smooth and steady, and the braking is reliable; a motor reversing is omitted, the efficiency is high, and the noise is low; accident potential of weight box falling is omitted.

Description

technical field [0001] The invention relates to an oil pumping unit, in particular to a reciprocating screw mandrel reversing oil pumping unit and a use method thereof. Background technique [0002] At present, there are many types of pumping units used in oil production in oil fields. Beam pumping units have many parts, heavy installation workload, low efficiency, complex equipment maintenance, high installed power, large energy consumption, large load changes, and short strokes. The hydraulic pumping unit has high energy consumption and low efficiency; the chain pumping unit is noisy and pollutes the environment with oil leakage; the motor forward and reverse pumping unit has a large starting current and low efficiency. Contents of the invention [0003] The object of the present invention is to provide a reciprocating screw mandrel reversing pumping unit and a method of use for the above-mentioned defects in the prior art. [0004] A reciprocating screw rod reversi...
