Lubricated vacuum pumps remind me of the phrase "well oiled machine, " one of our customer said, for something that runs smoothly, without many kinks and not making much noise. The exact opposite of a lubricated vacuum pump is the oil less vacuum pump. The main difference being one uses oil and is considered a wet pump and the other doe not use oil and is considered a dry pump. A low vapor pressure oil is used in the wet pump's pumping mechanism. Oil liquid and vapor must both exist in the pump's vacuum volume in order to function properly.
Lubricated vacuum pump systems each have their own unique type of oil requirements. Hydrocarbon, silicone and other varieties are some of the oils that especially formulated for specific vacuum applications. If a pump calls for hydrocarbon oil it can not be replaced with silicone oil.
Serving as a lubricant and as a way to trap gas molecules, vacuum pump oils are typically stable and chemically unreactive to other chemicals or elements as well as having a low vapor pressure. Mechanical pumps and diffusion pumps are two types of pumps that are under the umbrella of lubricated vacuum pump systems. Mechanical pumps use a hydrocarbon oil to lubricate the pumps' parts and vacuum seal. Diffusion pumps use either a silicone, hydrocarbon or perfluorinated polyether (PFPE) oil for its lubrication. This type of pump is only meant to pump from low pressures.
Dry pumps have no gas sealing fluids. Some dry pumps, however, may have lubricated gears or bearings. This type of pump is sometimes referred to as a "somewhat dry pump. "
As with many machines and other industrial devices, the length of use and efficiency of the vacuum pump's performance is dependent upon is care and maintenance. One can not create an oil free system by only replacing the oil sealed pumps that currently exist with dry pumps.
1, Reliability: High-quality materials, quality management according to ISO9001, CE certification requirements, automated processing equipment, computer control engineering can guarantee the production of standardized and precision products.
2, Comfortable environment: Air cooling equipment installed in the suction inlet, low noise, low vibration, use of lubricants can be a stable vacuum and exhaust pressure can be used in any place.
3, Easy to manage: Simple structure, the air cooling method, carbon air ring main parts replacement is simple, easy to assemble decomposition. Maintenance is simple and can be long-term use in the workshop.
4, Small size: Directly on the flange motor set up a direct connection of the vacuum pump air rings and cylinder, simple construct. Advantage of the cooling of the motor cooling fan, a small size, light weight.
5, Low Noise: According to decades of improvement and research, this series of pumps running sound is very quiet, does not produce annoying noise.
