Abstract

The invention provides a gather and delivery pump set for thick oil containing sand, which relates to a gather and delivery pump set. The invention aims to solve the problem that the traditional common pump has the disadvantages of low efficiency, high power consumption, poor abrasion resistance, short service life and high oil extraction production cost when used for delivering thick oil containing sand. One side of a pump casing is provided with an oil inlet, and the other side is provided with an oil outlet; a driving shaft and a driven shaft are arranged in the pump casing and a gear cover; the driving shaft and the driven shaft are respectively and fixedly provided with a synchronizer gear, and the two synchronizer gears are meshed with each other; the driving shaft and the driven shaft are provide with a first bearing pedestal and a second bearing pedestal, and are also respectively provided with a rotor; sector vanes on the two rotors are perpendicular to each other; the rotating clearance between the rotors and the pump casing is 0.36mm; an output gear of a speed reducer is fixedly arranged on an input shaft of the driving shaft; an input gear of the speed reducer is connected with an output shaft of a motor in a driving manner; and the motor is fixedly arranged on a motor base. The invention has the characteristics of good sealing effect, good abrasion resistance, high efficiency, low power consumption, long service life and low oil extraction cost. The gather and delivery pump set is mainly used for storage, gather and delivery in an oil project.

Description

technical field [0001] The invention relates to a collection and transportation pump set. Background technique [0002] Oilfield gathering and transportation pumps (ie, process pumps) are the main types of fluid machinery in petroleum engineering storage and transportation, and are widely used in oil refineries and petrochemical plants. Therefore, the long-term reliable operation of the pump is one of the crucial prerequisites for the continuous production of petrochemical enterprises, and at the same time, the pump is the most important equipment that consumes electricity in petrochemical enterprises. However, the functions of most of the pumps actually used are not many for on-site use. Moreover, with the development of heavy oil, it is found that the crude oil in the output fluid of many oil fields (such as: Liaohe, Shengli, Karamay, Henan and South China Sea) has high viscosity, Multi-phase flows containing sand, entrained gas, and water-containing emulsions are transpo...
