Multi-cylinder gravity type stroke-adjustable instillation pump

Abstract

The invention discloses a multi-cylinder gravity type stroke-adjustable instillation pump. The multi-cylinder gravity type stroke-adjustable instillation pump comprises a traction part, a pump body part containing a plurality of cylinder bodies and a gravity part dragged by the traction part. The pump body part containing the multiple cylinder bodies is mounted on a mounting bottom plate, the gravity part is mounted on the pump body part, the traction part is mounted on the gravity part, the traction part is connected to a power mechanism, and the gravity part can move up and down along with the traction part under the action of the power mechanism. According to the instillation pump, continuous trace dosing of each well can be realized; and meanwhile, the investment cost of equipment is greatly reduced through the combined design, the working efficiency is improved, and the process breakthrough that two kinds of chemicals are added into one well at the same time or chemicals are added into multiple wells at the same time is achieved. Meanwhile, stepless regulation of the dosage is realized. Through the arrangement of a balancing weight, constant filling pressure is achieved, safe operation of the equipment is ensured, meanwhile, the dosage is saved, various manual filling costs are saved, the oil well yield is indirectly improved, and the service life of an oil well is prolonged.

Description

technical field [0001] The invention relates to the technical field of plunger pumps, in particular to a multi-cylinder gravity stroke-adjustable infusion pump. Background technique [0002] Oilfield dosing machine is a widely used equipment and an important means to increase and stabilize production. Dosing oil wells and oil pipelines is a routine process. The current dosing methods are as follows, one is manual and extensive regular dosing. The second is to use conventional pumps (generally unable to achieve trace amounts) to do intermittent dosing to a single well or through automatic switching between dosing valve groups to dosing to each single well in turn. And generally only one medicament can be filled at a time. This is a discontinuous dosing process for each well. As the advantages of refined chemical dosing continue to emerge, oil fields have increasingly urgent requirements for continuous chemical dosing with small flow rates. But now all dosing methods cann...
