vacuum pump buying guide

Everyone knows that there are many types of vacuum pumps, such as liquid ring vacuum pump, rotary vane vacuum, Roots vacuum pump, molecular pump, diffusion vacuum pump and so on. The vacuum pumps used in different application industries are different. Next, the manufacturer of EVP vacuum pump will introduce some considerations when purchasing vacuum pump.

 

vacuum pump buying guide

 

When purchasing vacuum pumps, we must consider several problems and select the most suitable type of vacuum pumps. Purchase of vacuum pumps can start from the following aspects:

1. The required flow rate, pumping speed (which determines the size and type of the vacuum pump), pumping speed: the time spent by the vacuum pump in a unit time to extract the vacuum degree that the vacuum pump can extract must be determined by the volume, the volume and length of the vacuum tube.

2. The required vacuum degree or the ultimate pressure (deciding to choose a combination of vacuum pumps such as coarse vacuum pumps, high vacuum pumps, etc.) Vacuum degree: Vacuum degree that can be pumped by vacuum pumps, ultimate vacuum degree: the ultimate vacuum that can be pumped by vacuum pumps, note that the ultimate vacuum degree is the ultimate vacuum that can be pumped by vacuum pumps, and it changes with the sealing of vacuum pumps and the external air pressure.

3. Whether there are dust, plenty of water, processing fluid and corrosive liquid in the air, and whether explosion proof is needed.

4. Whether it can be used in vacuum unit system or not, vacuum system appliances have higher integration and reliability, products are more energy-saving and easier to maintain, can improve the stability of pumping speed and vacuum degree of vacuum pump, thus improving the overall performance of vacuum pump to achieve vacuum production efficiency.

Such as: semiconductor process vacuum, liquid crystal display process vacuum, electronic factory central vacuum system, hospital central vacuum system, food and medicine process vacuum, lamp process vacuum, refrigeration and air conditioning process vacuum, circuit board pressing process vacuum, optical lens, metal vacuum coating, scientific research instruments, vacuum for vacuum processing, exhaust control, sewage treatment system, gas location. Vacuum system recommendation: liquid ring vacuum pump unit

JZPS Roots-Liquid Ring Vacuum System：It can not only pump the common gas but also can pump the gas that contains vapor and a little dust.

5. In the application field of product equipment, vacuum pump manufacturer contains a large number of application cases of vacuum equipment. If it is the same production process, vacuum pump manufacturer can quickly help select the type.

For example: CNC engraving machine, vacuum moulding machine, semiconductor application, circuit board, photographic plate maker, circuit board vacuum elevator, vacuum sucker, printing machine, VCD&DVD disc surface vacuum sputtering, vacuum immersion, vacuum suction, vacuum pump for hospital negative pressure recommendation: liquid ring vacuum pump
