Key words: negative pressure roots blower

Roots blower Negative pressure applied to the system is called Roots vacuum pump A typical case is the application of negative pressure in gas transportation. It can be said that the pipeline is connected at the inlet of the fan. The gas enters the fan body and then is compressed and discharged from the outlet of Roots blower. It works in the same way as the positive pressure of Roots blower. It belongs to the volume blower.
 Roots vacuum pump

The structure of the whole equipment is basically the same, but some accessories are different. Roots blower belongs to blower system, which belongs to positive pressure fan, while roots vacuum pump belongs to negative pressure suction system and belongs to negative pressure fan category

First: different promotion capabilities

Since roots vacuum pump is sucked in, it needs the customer's atmospheric pressure. Therefore, it is more difficult to overcome the negative pressure. The positive pressure blower can be stronger at atmospheric pressure, with stronger positive pressure enhancement ability and wider pressure range.

Second, the price difference

Since roots vacuum pump is more difficult to manufacture, it is common Roots vacuum pump Will be higher than Roots blower Price.

Third: the difference in installation

Roots blower can be used after installation, and roots vacuum pump may need to be equipped with front stage pump when starting. The purpose of the front stage pump is to ensure that the roots vacuum pump will not rise to a very high negative pressure, so the front stage pump is required. First, increase the degree of negative pressure, and then turn on the vacuum pump to continue to increase the pressure.

Summary: Roots blower is used for air supply. Its main principle is to use three blade rotors to move relative to each other in the cylinder to compress and transport gas. The blower can also be used as a vacuum pump. The wind pressure is 0.1 MPa, which is a positive displacement fan. The amount of air delivered is proportional to the number of revolutions. The three blade impeller is inhaled and discharged by two impellers three times. There is always a small gap between the impeller on the two shafts of the fan, the inner hole surface of the elliptical shell, the end face of the impeller, the end face of the fan and the impeller of the fan, the front cover and the rear cover.

The roots vacuum pump negative pressure roots blower also has dozens of models and hundreds of parameters for you to choose from. The high pressure blower also has water cooling device. The vacuum pump effectively reduces the temperature of the fan oil tank and greatly extends the service life of the blower. Parameters of negative pressure roots blower: negative pressure-9.8kpa-50kpa, suction capacity: 1.12-180 m3 / min.
