For better use, you need to understand the oil-free diaphragm vacuum pump before using it. The oil-free diaphragm vacuum pump was developed after Market Research on the basis of the original cryogenic cooling fluid circulating pump and circulating water multi-purpose vacuum pump. It combines refrigeration function with vacuum function and is an internationally competitive product. Not only can it provide a constant cold source for the laboratory, but also it can keep the water temperature of the vacuum pump around 4 C, so that its vacuum can reach its limit.

Use characteristics of oil-free diaphragm vacuum pump:

1. Single stage double pumping

2. It does not need any working media (no oil or water) to operate and does not cause any pollution.

3. The machine is designed with new technology and new materials, compact and rational structure, small size, light weight, easy to move, stable operation, high vacuum and low noise, which can guarantee ideal vacuum effect or high flow air.

4. The diaphragm is made of PTFE and is resistant to various organic chemical gases.

5. A self-cooling exhaust system is designed to operate continuously for 24 hours.

6.Bearing uses imported classic bearing, which runs smoothly, has low noise and has high working efficiency

Daily maintenance of oil-free diaphragm vacuum pump:

1. Normally working bearings are 15-20 C higher than the surrounding temperature, temperature should not exceed 55-60 C:, normally working bearings should be oiled 3-4 times a year. Clean the bearings at least once a year and replace the lubricant tractor.

2. Check the working and lubrication of the bearing of the water ring vacuum pump frequently.

3. If the packing is sealed, the packing should be compacted regularly. If the packing cannot guarantee the required sealing performance due to wear and tear, a new packing should be replaced. Vacuum pump UK packing cannot be pressed too tight. Normally compacted packing allows droplets of water to drip out to ensure cooling and seal.

4. If the parking time exceeds one day, the water in the pump and the gas-water separator must be drained to prevent rust.

5. If a mechanical seal is used and leakage occurs, check whether the dynamic and static rings of the mechanical seal are damaged or the sealing rings are aged. If this happens, new parts should be replaced.
