A rotary-screw compressor is a type of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement mechanism. These compressors are common in industrial applications and r

Roots blowers can be roughly divided into single-stage and double-stage according to their working methods. Among them, there is only one compression stage blower, which we call a single-stage blower,

Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth projecting radially. Viewing the gear at 90 degrees from the shaft length (side on) the to

V-belt pulleys are for use with V-belts to transfer motion from motors to belts, fans, and pumps. They have V-shaped grooves that correspond with V-shaped belts to prevent slippage and misalignment. V

A labyrinth seal is a type of mechanical seal that provides a tortuous path to help prevent leakage. An example of such a seal is sometimes found within an axle's bearing to help prevent the leakage o

In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or

Reactive silencers are used to attenuate low frequency octave band noise – up to attenuation of 30 dB (A)- produced by the exhaust of rotating machines such as diesel / gas engines, compressors, pumps

A piston ring is a metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine or steam engine.

Oil seals – often called grease, fluid or dirt seals – close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. They also stop harmful contamina

The gas pressurized blower is a new type of gas discharge machine developed according to the development trend of the two-stage gas furnace and combined with the single-stage gas furnace.

Roots fan supporting inverter is an important means for many manufacturers to achieve energy saving. Some traditional power frequency equipment can also achieve more energy-saving operation by adoptin

Roots blower can be used to transport biogas, gas, air, oil and gas, etc. Because of the different gas properties, Roots blower needs special treatment. Which gases need special treatment for Roots bl
