Internally tangent double-barrel rolling type pump

Abstract

The invention relates to an internally tangent double-barrel rolling type pump, which is mainly characterized in that an outer rotor and an inner rotor are arranged in a pump shell, wherein the outer rotor is concentric with the pump shell; the inner rotor is positioned in the outer rotor and connected with a power machine; the inner rotor is composed of a main shaft, a double-ring single-beam bracket and a separation plate; and the double-ring single-beam bracket is sleeved on the main shaft and in rotary connection with the pump shell; the separation plate is movably connected with the main shaft and the double-ring single-beam bracket respectively. A main shaft inflow hole communicated with an inflow channel of the pump shell is communicated with a left working cavity through a left guide groove on the separation plate. A right working cavity is communicated with a main shaft outflow hole through a right guide groove on the separation plate. The surface contact position between the inner rotor and the outer rotor is kept in sliding friction. The tangent line contact position between the inner rotor and the outer rotor is kept in rolling friction. The pump is steady to operate, good in sealing property and high in working efficiency and has a self absorption capacity. The pump can be used for effectively reducing abrasion and heat loss and conveying various types of fluids. Due to extensive uses, the pump can be used for converting fluid energy into mechanical energy, converting the mechanical energy into the fluid energy, converting the fluid energy into the mechanical energy and then converting the mechanical energy into the fluid energy, and converting the mechanical energy into the fluid energy and then converting the fluid energy into the mechanical energy.

Description

technical field [0001] The invention relates to a volumetric rotary pump, in particular to an inscribed double-tube rolling pump, which is suitable for conveying various fluids. Background technique [0002] The pump is an energy conversion device that drives the medium to move under the control of the power machine and converts the energy output by the power machine into the pressure energy of the medium. Pumps can be used to transport many types of fluids and fluids, gas mixtures and fluids containing suspended solids. Pumps have extensive and important applications in military weapons and equipment, transportation tools, and national economic construction. Usually, there are many types of pumps used, and the gear pump is a kind of positive displacement rotary pump, which includes a pump casing and a gear rotating mechanism arranged in the pump casing. The rotating mechanism of this kind of pump realizes the rotation variable capacity through the gear meshing movement, w...

AI Technical Summary

Problems solved by technology

However, it has defects such as large flow and pressure pulsation, large vibration and noise, and invariable displacement.

Moreover, due to the unbalanced radial force borne by the pump, the meshing gears in the pump casing are easy to wear during long-term operation, resulting in large leakage and poor sealing effect

Also, the flow rate of the conveying medium is small, so it is not suitable for conveying fluids containing solid particles and fluids with high volatility and low flash point, which limits the types of conveying fluids
