? Product Introduction
High pressure Roots blower It is composed of four major parts: casing, wallboard, impeller, inlet and outlet muffler, etc.
Casing: mainly used to support wallboard, impeller, muffler and fixation.
Wall plate: mainly used to connect the casing and the impeller, support the rotation of the impeller, and play the role of end sealing
Impeller: It is the rotating part of the high-pressure Roots blower, which is divided into two leaves and three leaves. Now, the three leaf blower has gradually replaced the two leaf Roots blower because of its advantages such as less air pulsation, less noise and smooth operation than the two leaf blower.
Muffler: It is used to reduce the noise caused by air flow pulsation at the inlet and outlet of high-pressure Roots blower.
The following figure shows the disassembly of high-pressure Roots blower
? Performance characteristics
(1) High pressure Roots blower The operating pressure is 58.8kPa-98kPa.
(2) The impeller of high-pressure Roots blower adopts compound profile, with perfect meshing, less leakage and high efficiency.
(3) The impeller of high pressure roots blower is made of nodular cast iron, the contour is processed by CNC machine tools, the gear is of Class 5 accuracy, imported bearings are used, and the rotor dynamic balance quality is not lower than Class G6.3, so the product has low noise and reliable operation.
(4) The air volume of high-pressure Roots blower can range from 0.78 m3/min to 198.1 m3/min, with large coverage and wide application range.
(5) The whole product has compact structure, small volume and light weight.
(6) Long service life and simple maintenance.
