The same vacuum pump products, why is it divided into many kinds?Because of the different industry fields and the use of the environment, the different series and specifications of vacuum pumps will also be different.Although there is only a word difference between screw vacuum pump and Roots vacuum pump, there is a great difference in performance and application.

Dry screw vacuum pump is a common vacuum equipment used in vacuum systems in various industries. Before the official launch, we need to carry out a series of inspection work to ensure that the equipment is smooth and reliable during operation. The following is a dry screw vacuum pump needs to be checked before starting. First, the opening of the air intake and air outlet before starting, check whether the opening of the air intake and air outlet is normal. If the inlet and outlet are not opened correctly, it will lead

1. When the dry screw vacuum pump has abnormal noise or violent vibration, it must be shut down immediately for corresponding maintenance work.2. Personal safety accidents occur due to operating environment problems.3. The current of the motor suddenly fluctuates greatly.4 Dry screw vacuum pump due to the temperature in the pump exceeds the specified value, resulting in smoke or burnt taste.5. Evacuation or cavitation occurs, abnormal changes in pump pressure, and pump body burns.6. The pump body pricks water, the machine pump rotor is shifted or the water injection station system can leak. The pipeline is ruptured.7. Bearing bush water, lubricating oil serious discoloration, or high water content.8. The water injection pipeline has high pressure, small displacement or can not be drained, and low efficiency.As long as the above situation occurs when we use the screw vacuum pump, we must immediately stop the equipment for inspection, deal with the problem immediately after finding it, and then start to continue to use it.

In terms of display devices, the transparent conductive film of video head, high-density video tape and flat display device, the photoconductive film of the camera tube, and the aluminum lining of the fluorescent screen of the display tube are also prepared by vacuum coating method. In terms of components, the evaporation of nickel chromium in vacuum, chromium or cermet can make resistors, the evaporation of aluminum, silicon monoxide, titanium dioxide, etc. on plastic can make capacitors, the evaporation of selenium can get the toner cartridge for electrostatic copiers, the evaporation of barium titanate can make magnetostrictive sound components, and so on. Vacuum evaporation can also be used to produce superconducting films and microbead coatings for inertially confined seismic reactions. In addition, it can also steam decorative films for jewelry, watch shell surface, textile metal pattern, gold wire and silver wire, as well as the use of sputtering or ion plating on tools, molds and other manufacturing superhard film. In the past two years, the rise of multi-arc ion plating to prepare titanium products, such as stainless steel sheet, mirror plate, column, handrail, high-grade bed brackets, stair railings and so on are currently prevailing.

The use of vacuum pumps is usually related to water, but it still needs water to support its work. A lot of times we do it by adding water. What is the saying about adding water to the vacuum pump? When the vacuum pump is running, it is necessary to use liquid as the working liquid, basically choosing water as the working liquid. As the impeller rotates clockwise, water is tossed around by the impeller. Due to centrifugal force, the water forms sealed rings of roughly equal thickness determined by the shape of the pump chamber. The inner surface of the lower part of the water ring is positive

Medical negative pressure suction device, also known as suction device (negative pressure suction system), is a commonly used and necessary rescue equipment in clinical departments. The operating room is an important place for the treatment of various surgical diseases, and it is used frequently. The negative pressure suction device in the operating room is used to attract the bleeding, exudate, pus, contents in the cavity organs and flushing liquid during the operation, so that the field of vision is clear during the operation, reduce the chance of contamination, and can also be used for suction sputum in patients with general anesthesia. O.r. negative pressure suction device is
