Problems solved by technology

Generally, the service life of the valve is only one month, and the replacement of the valve is time-consuming and expensive, which reduces the processing efficiency
Because of the presence of abrasives, it is not suitable to use a centrifugal pump. Generally, it will be unusable due to poor sealing after three months of use.

Abstract

The invention relates to an adjustable-pressure automatic stirring liquid supply system belonging to the field of liquid supply. The adjustable-pressure automatic stirring liquid supply system comprises a locking mechanism (1), a constant pressure barrel (2), a scale plate (3), a positioning barrel support (4), a sludge pump (5), a grout barrel (6), a filter (7) and a grinding and polishing machine (8); a special connector is designed to realize automatic stirring of the grout, and a backflow pipeline is arranged to realize constant pressure of the entire system; the pumping quality can be effectively improved by pumping the grout through the sludge pump (5), and the abrasion to the pump is reduced; the adjustable constant pressure barrel (2) is designed to control the flow velocity of the grout, so as to realize valveless design; and the automatic stirring of the grout can be realized due to the design of the special connector, the pumping quality can be effectively improved, the faults are reduced, the service life of the liquid supply system is prolonged, and the production efficiency is improved to a certain extent.

Description

Technical field: [0001] The invention belongs to the field of liquid supply, in particular to the liquid supply of grinding liquid and polishing liquid for grinding and polishing machines, and is also applicable to the liquid supply of various metal cutting machine tools, in particular to a pressure-adjustable self-stirring liquid supply system. Background technique: [0002] Ultra-precision machining technology refers to the general term for all manufacturing technologies whose machining accuracy can reach a certain level, mainly including ultra-precision cutting (turning, milling), ultra-precision grinding, ultra-precision grinding (mechanical grinding, mechanized grinding, polishing, Non-contact floating grinding, elastic launch processing, etc.), and ultra-precision special processing, etc. During precision machining, abrasives are transported to the machining area through a liquid carrier. The grinding liquid is usually formulated with lubricants, overstocking agents, ...
