Problems solved by technology

However, the injection volume of this pneumatic fluid injection device is not accurate enough
First of all, it is not easy to precisely control the operation time of the above-mentioned fluid injection equipment, which is specifically manifested in the large time error of manual or automatic opening and closing of pneumatic valves; secondly, the liquid flow is particularly susceptible to air pressure fluctuations and interference from external factors, and also Due to the pneumatic control, it is necessary to maintain a large air pressure and maintain airtightness, so that the pneumatic fluid injection has the defects of high equipment failure rate and high maintenance cost

Abstract

The invention belongs to the technical field of manufacturing, and relates to equipment for fluid quantitative injection. The injection equipment comprises a power mechanism (1), a piston mechanism (2), and a cylinder body (3); wherein the piston mechanism (2) comprises a transmission nut (2.5), a screw rod (2.8), and a piston (2.1); the power mechanism (1) is connected to the transmission nut (2.5) and drives the transmission nut (2.5) to rotate; then the transmission nut (2.5) drives the screw rod (2.8) to drive the piston (2.1) to move in a straight line in the cylinder body (3); the piston (2.1) pushes the fluid in the cylinder body out of the cylinder body, and thus the quantitative injection is completed. The equipment is difficult to interfere by outer factors, and has the advantages of high quantitative precision, simple structure, and easy maintenance.

Description

technical field [0001] The invention belongs to the field of manufacturing technology and relates to a fluid quantitative injection device. Background technique [0002] At present, in the process of automatic dispensing and lubricating grease, the fluid injection equipment drives the fluid to flow in the pipeline through compressed air or a high-pressure pump, and controls the injection volume by controlling the opening and closing time of the pneumatic valve. However, the pneumatic fluid injection device is not accurate enough to inject volume. First of all, it is not easy to precisely control the operation time of the above-mentioned fluid injection equipment, which is specifically manifested in the large time error of manual or automatic opening and closing of pneumatic valves; secondly, the liquid flow is particularly susceptible to air pressure fluctuations and interference from external factors, and also Due to the pneumatic control, it is necessary to maintain relat...
