What is piston vacuum pump?

Piston vacuum pump is a kind of portable vacuum equipment with good quality, excellent performance, high reliability and reasonable price. It is mainly used in medical products analysis, fine chemical industry, biochemical pharmaceutical, video detection, analysis and other fields. It is one of the necessary equipment in the laboratory.

piston vacuum pump application

Piston vacuum pump can be widely used in automotive industry, automatic control, printing machinery, packaging machinery, food preservation, aquaculture, water purification, analysis instruments, beauty and health care, equipment maintenance, biopharmaceuticals, communications electronics, petrochemical industry, environmental detection system, oxygen production in plateau areas and other fields; A society needs purity and purity. The choice of environmental vacuum space.

Piston vacuum pump structure

The main components of piston vacuum pump are front cover, motor cooling fan, piston ring, piston connecting rod, sleeve, cylinder and valve metal plate. In addition to the main components mentioned above, there are important components such as exhaust valves, suction valves, seats, crankcases, dynamic seals, static seals and other auxiliary components.

piston vacuum pump working principle

When the piston vacuum pump is running, the piston in the cylinder moves back and forth through the action of crank and connecting rod driven by electric actuator. When the piston does not move from the left end of the cylinder to the right end, the pressure in the left chamber space decreases as the volume of the left end of the cylinder increases. When the pressure in the left end space is lower than that in the pump vessel, according to the principle of air pressure balance, the gas in the pump vessel is continuously pumped into the left chamber through the suction valve. At this time, it is in the right place. In the inhalation process. When the piston reaches the correct position, the left chamber of the cylinder is filled with gas. Then the piston moves from the right side to the left side, and the suction valve automatically closes. When the piston moves from right to left, the gas gradually compresses. When the gas in the cylinder reaches the exhaust pressure, the exhaust valve is opened and the gas is discharged to complete the work cycle. When the piston moves from the left end to the right end, repeat the above cycle in order to obtain a stable balance pressure in the pump container, thereby improving the pumping efficiency. Usually, there are suction valves and exhaust valves at both ends of the cylinder. Then, the suction port and the exhaust port at both ends of the cylinder are connected in parallel through the pipeline.

piston vacuum pump advantages

Piston vacuum pump has the characteristics of high efficiency, energy saving, safety, environmental protection, stable operation, long service life, low temperature rise, small size, light weight, beautiful appearance, simple structure, safety, oil-free, easy maintenance and so on. Because of its precise structure and the use of modern advanced technology, its noise level is only between 50 and 60 decibels, thus keeping the environment quiet and avoiding noise interference to operators and others. From 50L / S to 60L / S, it is used as delivery pump for pumping non solid particles and non corrosive gases. The vacuum pump has higher pumping speed and higher vacuum.

Piston vacuum pump is very suitable for the manipulator with vacuum adsorption technology to carry small pieces of materials in the current automation industry. The vacuum sucker is very suitable for grasping thin and smooth metal products, glass, mobile phone panel, electronic components, paper and so on. It achieves stable and efficient work efficiency. In automatic production lines such as product packaging, object transmission and mechanical assembly, more and more piston vacuum pumps are used to grab objects. Flexible and flexible sucker can easily realize the absorption, separation and transmission of the workpiece, and ensure that its functional object is not damaged.
