Sliding vane pump and method using sliding vane pump to convey fluid

Abstract

The invention provides a sliding vane pump and a method using the sliding vane pump to convey fluid. The sliding vane pump is provided with a cylindrical pump casing, and the pump casing is internally provided with a driving shaft, a rotor sleeved on the driving shaft, and a sliding vane arranged on the rotor, wherein the sliding vane and an inner cavity of the pump casing are sealed in a contact manner; an end cover is arranged at the end part of the pump casing; the sliding vane pump further has a sliding vane pump suction port and a sliding vane pump discharge port; and the sliding vane pump suction port and / or the sliding vane pump discharge port are located on the end cover of the pump casing. The invention further provides a sliding vane pump, and the sliding vane pump includes a plurality of cylindrical pump casing, and has a sliding vane pump suction port and a sliding vane pump discharge port; the sliding vane pump suction port and / or the sliding vane pump discharge port are respectively located on the end cover; and fluid transfer openings penetrating the upper end surfaces and the lower end surfaces of partitions are arranged on the partitions. According to the method using the sliding vane pump, the fluid is sucked and / or discharged in the direction of the end part of the pump casing so as to pump.

Description

technical field [0001] The invention relates to the hydraulic field, in particular to a sliding vane pump and a method for transporting fluid by using the sliding vane pump. Background technique [0002] Sliding vane pump is a commonly used positive displacement pump, which is widely used in the industrial field of gathering, transportation and lifting. It has strong self-priming ability, and is especially suitable for unloading oil at the wharf of oil tankers, cargo oil on board, stripping tanks, and unloading tanks by trains. And other occasions, as well as oil tank trucks, fuel trucks, oil depots, and gas stations for oil delivery. Sliding vane pumps can be used to transfer light oils, and viscous oils are better. The working principle of ordinary single-acting sliding vane pump is as follows: figure 1 shown. Generally, the single-acting sliding vane pump is mainly composed of the following parts: drive shaft 1, connecting key 2, rotor 3, vane 4, also called blade, and...
