Fluid machinery with a rotary piston structure

Abstract

The invention relates to pumps with revolving piston structures, related products and a part of embodiments. Each pump is characterized in that the pump comprises a C-shaped annular cylinder body which is composed of multiple parts, the piston of the pump is pulled and controlled through a double crank transmission mechanism and carries out circular revolving translation around the cylinder body under the driving of a rotor. The pump has the characteristics of simple structure, easy manufacturing, low wear, high rotating limit speed and direct ratio liner change of the volume. When the pumps are used for manufacturing metering pumps and flow meters, micro-metering and precision metering can be achieved; when the pumps are used for manufacturing hydraulic pumps (motors), the hydraulic pumps are smooth in flow rate, free of noise, good in hydroscopicity and low in cost and can be used to replace gear pumps (motors), centrifugal self-priming pumps, submersible pumps and the like; when the pumps are used in fluid pumps such as fire pumps, water supply pumps for buildings and the like, the fluid pumps are high in pressure and energy-saving; when the pumps are used in hydraulic water lifting pumps and dust-removing negative-pressure suction fans, the energy consumption can be greatly reduced, the energy utilization rates of power devices for hydroelectric generation can be improved. The pumps are also high in vacuum degree and can be used for manufacturing vacuum pumps. The structures of the pumps are ideal pump structures and extremely wide in application scope and market prospect.

Problems solved by technology

However, the piston’s circumcircle translation and crossing structure has not been involved so far, but to realize it, the problem of the piston’s circumcircle translation must be solved

According to the motion characteristics of the connecting rod in the constant velocity double crank transmission mechanism, the present invention successfully solves this problem and creates an ideal product structure such as pumps (motors)
