Input cost characteristics of dry vacuum pump: 1 high and 2 low

Steam jet pumps, wet pumps, and dry pumps are commonly used vacuum pump types. In recent years, due to the increasing attention to energy conservation and emission reduction and environmental protection, dry pumps have been paid attention to and selected by more people in the industry.

Dry pumps are mainly three types: roots pumps, screw pumps and claw vacuum pumps. The input cost characteristics of dry vacuum pumps can be simply summarized as 1 high and 2 low, that is, the investment cost is higher, but the operating cost and maintenance cost are lower.
Oil-free dry mechanical vacuum pump, referred to as dry mechanical pump, refers to the pump can start pumping from atmospheric pressure, and can be pumped gas directly into the atmosphere, no oil or other working medium in the pump cavity, and the ultimate pressure of the pump is the same order of magnitude or close to the oil-sealed vacuum pump.

Features of dry vacuum pumps:
--- there is no contamination of industrial production streams
--- deep vacuum for more flexible operation
--- no wastewater, no pollution, less or no waste disposal costs
--- immediate recovery of solvents at the pump drain
--- consumes less water, electricity, gas, etc. (lower operating costs)
Specific description of the cost of dry pumps
The investment cost is higher
Low maintenance costs
Lower operating costs
   — Extend the interval between service repairs and bearing life.
   - In the operating range, the power consumption is low. Therefore, the energy saving effect is better in terms of energy-to-energy ratio.
   - Oil that is not contaminated is to be treated (other than the handling gearbox).


The application of dry vacuum pump is widespread, which can be used for polysilicon preparation process, semiconductor etching process, as well as distillation, drying, defoaming, packaging and other fields in the chemical industry, pharmaceutical industry, food industry is also suitable for the use of dry vacuum pumps.
