When installing rotary vane vacuum pump must comply with certain rules: a small displacement pump (moving piece and set-piece) should be fixed at a fairly large base, and to take into account when installing the pump, using a process accessible in order to observe its work and replaced with new o...

Consider a vacuum system with a vacuum pump which, at first, according to the requirements of the system, followed by the performance characteristics of the pump to respond in detail to understand, compare the advantages and disadvantages of various pumps, and then decide it, so as to get the pro...

Vacuum technology is the use of vacuum pumps, vacuum unit and other vacuum systems to accomplish a specific process technology, in a variety of industrial production and research work has been widely used. Such as: petroleum (vacuum distillation), chemicals, canned food, metallurgy, light bulbs a...

Turbo molecular pump suction principle is to use the high-speed rotation of the rotor to transfer momentum to the gas molecules, and thus obtain the orientation speed, so as to be compressed, is driven towards the exhaust port for the first stage is drawn away after a vacuum pump. Molecular pumpi...

The connected vacuum gauge ...

SK series liquid ring vacuum pump inexpensive, simple operation, easy maintenance, can extract corrosive, flammable gas, but also dust extraction, water gas, it is widely used in food, machinery, petroleum, ceramics , chemical, pharmaceutical, sugar refining, metallurgy, printing and dyeing indus...

Vacuum pump observation window design ① perspective pump observation windows should meet the requirements of the observation site, in this condition, keep it simple and compact structure. ② for observation windows at high temperatures, do not let the seals should be considered directly affected b...

1, the impact of the condensate: Condensate having insignificant position in a multistage vacuum pump in order to ensure plenty of condensed water vapor can be condensed, pump discharge pressure of water vapor partial pressure higher than necessary to its corresponding full vapor pressure, so the...

1, the overall structure of the roots vacuum pump Roots vacuum pump arrangement determines the overall structure of the pump. At present, the overall structure of the domestic and foreign Roots vacuum pumps are basically three types: Intake and exhaust ports arranged horizontally, assembly and co...

1. Introduction Scroll oil-free vacuum pump concept is quite old, early 20th century have patented vortex technology in the world. However, due to technical limitations at that time, oil-free scroll vacuum pump bodies manufactured out, scroll concept will be forgotten. 1973 scroll mechanism being...
