Tray-piston type swing executor driven tray-piston type swing pressure-feeding fluid machine

Abstract

A tray-piston type swing executor driven tray-piston type swing pressure-feeding fluid machine comprises a support, a tray-piston type swing executor in a tray-piston type swing executing device, a tray-piston type swing pressure-feeding fluid machine head, a cooling system, and a driving force generating system. The tray-piston type swing executor comprises an executor fixed swing tray set, and / or an executor piston cylinder piston set, and an executor fluid in / out channel system. The tray-piston type swing pressure-feeding fluid machine head comprise a pressure-feeding fluid fixed swing tray set in the tray-piston type swing executing device, and / or a pressure-feeding fluid piston cylinder piston set, and a pressure-feeding fluid machine head fluid in / out channel system. The tray-piston type swing executing device comprises at least one fixed swing tray set, a connection mechanism, a power in / out bonding structure, a lubricating system, and a sealing structure. The fixed swing tray set comprises a fixed tray, a piston sheet, and a swing tray. The angular travel range of the swing piston sheet is 0 to 300 degrees or so. The pressured fluid drives the piston sheet to pressurize the fluid to carry out pumping.

Description

technical field [0001] The invention relates to a pallet piston type rocking pressure fluid machine driven by a pallet piston rocking actuator. The range of reciprocating swing of the rocking piston piece is about 0° to 300°, and is suitable for driving the rocking piston piece to press and feed fluid for pumping work. ; The pressure-feeding fluid machine drives the piston to press-feed the fluid and the power source are both gas or liquid. Background technique [0002] There are centrifugal pumps, plunger pumps and piston compressors in the existing disclosed pressure-feeding fluid machinery. During the power output process of the piston compressor, the stress intensity on the load-bearing parts shows a peak-to-valley value change from small to large, and the connecting rod and the pin shaft on the piston, which are the highest stress-bearing parts, become the weak links that affect the service life. In addition, due to the need to meet the strength requirements of a large...

AI Technical Summary

Problems solved by technology

[0002] There are centrifugal pumps, plunger pumps and piston compressors in the existing disclosed pressure-feeding fluid machines, and the pressure of the fluid pumped by the centrifugal pumps is difficult to meet the requirements of higher pressure when the flow is small and the speed is low; During the power output process of the piston compressor, the stress intensity on the load-bearing parts shows a peak-to-valley variation from small to large, and the connecting rod and the pin shaft on the piston, which are the highest stress-bearing parts, become the weak links that affect the service life. In addition, due to the need to meet the strength requirements of a large peak stress, many parts are basically made of metal materials, and the anti-corrosion performance of metal materials is significantly lower than that of organic composite materials; these mechanical parts have many types, complex structures, and high costs. Mechanical work efficiency is low
