The environmental protection plan clearly points out that it is necessary to form a resource-saving, environment-friendly and intrinsically safe development model in the future. With the “low-carbon environmental protection storm” becoming more and more fierce, the vacuum pump manufacturing industry, which is increasingly aware of energy conservation and environmental protection, has begun to actively participate in this “green new wind”.
Oil free vacuum pump series rotary vane vacuum pump is a kind of mechanical vacuum pump which can run without any oil. The utility model has the advantages of simple structure, easy operation, convenient maintenance and no environmental pollution. The two series of oil-free vacuum pumps have good durability. They are vacuum pump, compression pump and dual-purpose vacuum pump. They are a basic equipment with a wide range of applications to obtain vacuum. Its working principle is the same as general positive displacement pump, which is composed of stator, rotor, rotor, cylinder, motor and other main parts. The rotor with rotor blades is installed in the fixed cylinder eccentrically. When the rotor rotates at a high speed, four radial sliding rotors in the rotor slot divide the pump cavity into four working rooms. Due to the centrifugal force, the rotor blades are closely attached to the cylinder wall, separating the inlet and outlet of the stator, and then the rotor starts to operate around, change the volume, and exhaust the gas from the exhaust port, so as to achieve the purpose of air extraction. The oil-free dry mechanical vacuum pump (also referred to as dry mechanical pump) refers to a mechanical vacuum pump that can start pumping from atmospheric pressure, and can discharge the pumped gas directly to the atmosphere. There is no oil or other working medium in the pump cavity, and the limit pressure of the pump is the same or close to that of the oil sealed vacuum pump.
For ordinary oil-free vacuum system, although oil sealed vacuum pump and accessories such as cold well or adsorption well can be used to prevent backflow, it can not completely solve the problem and make the system appear complex. The use of a suitable type of dry mechanical vacuum pump can achieve ideal results, while the noise is very small, with good environmental protection effect. Can be said to be an efficient low-carbon environmental vacuum pump.
Therefore, the enterprises in vacuum pump industry should increase the investment in research and development of dry oil-free vacuum pump, and promote the industrialization and technology upgrading of dry oil-free vacuum pump. At the same time, promote the combination of scientific research and production of dry oil-free vacuum pump, encourage dry oil-free vacuum pump manufacturers, universities and scientific research institutions to carry out technical cooperation in various ways, and accelerate the transformation of new technology achievements.
The control technology constantly optimizes the pumping speed, so that the flow rate can fully meet the actual process requirements of vacuum application. Compared with the traditional pump, the process runs faster and reduces energy consumption by 90%.
The new products we developed are characterized by reduced material consumption, reduced carbon footprint and positive environmental protection.
