The surface treatment of the workpiece before painting is an important guarantee and measure to obtain a high-quality protective layer and prolong the service life of the product.
This article mainly introduces the application of rotary vane vacuum pump in high-speed paper machine. The dryness of the paper sheet is relatively uniform, and the broken ends are less during pressing.
In addition to the application in thin film technology, our rotary vane vacuum pumps are also often used in: Measuring instruments and leak detectors. Food vacuum packaging. Eco-friendly refrigerator. Air conditioner. Flat panel display.
Rotary vane vacuum pump is clean and pollution-free, and has a wide range of pumping speed and good energy saving, stability, easy maintenance and other advantages. It is widely used in the semiconductor industry.
The vacuum pump is one of the necessary equipment for RH refining equipment. Its pumping capacity, pumping rate and other parameters directly affect the normal operation and metallurgical effect of RH furnace.
Vacuum forming is also a commonly used thermoforming method for the production of plastic packaging containers, which is widely used in the processing and packaging material industry.
Rotary vane vacuum pumps are used in steam turbine engines to remove excess steam and condensate. The steam turbine uses a sealing tube to seal the shaft to avoid air leakage. These sealing tubes are sealed with steam.
The rotary vane vacuum pump is used in the "air-filled" mixing box to generate a pressure/vacuum above the raw material level (or "raw material pool") of the mixing box to maximize the control of the material discharge rate (" jet" speed).
Vacuum technology has penetrated into various fields in the development of industrial production and modern science, and has become an indispensable part of national defense, national economy, and scientific research departments.
The correct use method of the electric heating vacuum drying box: first use the rotary vane vacuum pump to vacuumize and then heat up. After reaching the rated temperature, if the vacuum degree is found to have dropped, then add it properly.
Rotary vane vacuum pump solves the problems that food plastic bags can't be sterilized, can't be reused, and cannot be insulated, better ensure food hygiene and safety, and greatly reduce environmental pollution and resource waste.
The sewage suction truck mainly relies on the function of the vacuum pump. Generally, there are two different vacuum pumps used, one is a water ring vacuum pump, and the other is a rotary vane vacuum pump.
