Technical field
The utility model relates to a kind of pump, is a kind of reciprocating pump that is used for operations such as oil drilling, oil recovery fluid injection and pressure testing specifically.
Technical background
Reciprocating pump is that a kind of to-and-fro motion by piston or plunger changes the volume of liquid in the fluid cylinder, thus the pump that liquid is discharged under working pressure.Because this pump all has higher efficient under various discharge capacities, and flow rate of liquid is lower in it, when the liquid of pumping high viscosity, high sediment concentration, can not resemble each parts of the runner that weares and teares the higher centrifugal pump of flow rate of liquid, therefore be widely used in the factory of oil ore deposit.For example, the slurry pump in the drilling well, well cementation pump, the deep-well pump in the well-flushing pump in the oil producing operation, acid fracturing pump, oil transfer pump and some water injection pump, the pumping unit etc. all adopts reciprocating pump.But because all the rotatablely moving of general prime mover output, and input reciprocating piston pump or plunger should be to-and-fro motion, therefore, reciprocating pump need rotatablely move prime mover and become the lower to-and-fro motion of speed.Like this, reciprocating pump need adopt reducing gear and intermediate transmission mechanism, waits as gear reduction box, pulley decelerates, connecting rod, cam mechanism and realizes rotatablely moving reciprocating conversion, thereby make existing reciprocating pump have following shortcoming:
1, complex structure, the weight of specific power is big, and mechanical loss is big, the manufacture cost height.And because the working environment of general oil drilling or ore deposit factory is relatively disliked slightly, the structure of this complexity is more fragile, influences the proper functioning of entire equipment.
2, easily damaged parts is many, and the requirement height of maintenance has increased the maintenance expenses of reciprocating pump, and has reduced the working life of reciprocating pump, thereby causes the user cost height of reciprocating pump.Therefore, under the situation that pressure is not high in that liquid is clean, viscosity is lower, people still are preferred vane pump generally in order to reduce the cost, thereby have limited the application of reciprocating pump.
3, owing to complex structure, volume is big, and floor space is big, moves and the carrying trouble.Therefore, be necessary to propose the defective that a kind of novel reciprocating pump overcomes above-mentioned existing reciprocating pump.
