Vacuum suction cup is one of the actuators of vacuum equipment. The material of suction cup is made of nitrile rubber, which has a great breaking force. At the same time, vacuum suction cup adopts the principle of vacuum, and uses vacuum negative pressure to “absorb” the workpiece to achieve the purpose of manual handling. Vacuum absorption is a very easy to master transmission technology, which can be effectively adjusted, controlled and monitored by using vacuum pump Improve the automation of workpiece, semi-automatic production and parts, reduce the difficulty of work and improve the efficiency. Moreover, vacuum adsorption has the advantages of cleanness, stability, reliability and no damage to the surface of the adsorbed objects. Therefore, it is widely used in various vacuum adsorption equipment, such as in the construction, paper industry, printing, glass and other industries, to achieve the task of absorbing and transporting thin and light objects such as glass and paper. So what are the commonly used types of vacuum pump?
What are the commonly used types of vacuum pump? EVP vacuum pump manufacturers collate several types:
1. Rotary vane vacuum pump
The rotary vane vacuum pump is one of the most common vacuum equipment in vacuum technology. Rotary vane pumps are mostly small and medium-sized, there are two kinds of single-stage and two-stage. The so-called two-stage is to connect two single-stage pumps in series in the structure. Generally, they are made into two-stage ones to obtain higher vacuum. It has high vacuum degree, good pumping efficiency and gas ballast, and is favored by some sucker factories.
2. Water ring vacuum pump
The water ring vacuum pump is also commonly used in the vacuum suction cup. The water ring vacuum pump has high suction rate, good gas ballast performance, high suction negative pressure, small flow, stainless steel corrosion resistance and good safety, so the vacuum suction cup is often equipped with the water ring vacuum pump.
3. Screw vacuum pump
The screw vacuum pump system is the most popular one in the vacuum sucker market at present. It is clean in appearance, high in efficiency, energy saving, stable in operation and low in noise. Now there are also regular customers who carry out the old pump transformation plan, using a screw vacuum pump instead of several pumps of water ring pump or rotary vane pump to operate, which can save electricity cost.
The above three vacuum pumps are the types of vacuum pumps commonly used in vacuum suction cups, and some customers will ask which one is better to use. This has to be selected according to the actual situation. If you don’t understand, you can directly contact the EVP vacuum pump manufacturer to make a plan and select the most suitable vacuum pump for your own vacuum suction cups. As the main part of vacuum suction cup, vacuum pump must be selected carefully in order to maximize efficiency.
