Gland type, skeleton type and mechanical seal as a Roots blower sealing the 3 ways, about these 3 ways Roots blower I made the following detailed introduction, so that you can more clearly understand. 1, gland type: This is a simple structure, the more commonly used form of sealing, mostly used for conveying air. There are four gland-type seals in the connecting part with the cylinder, and several rings of asbestos oil packing are loaded in the gland packing box, in order to narrow the axial length, the sealing is considered to be close to the bearing at the time of design. During operation, the bolts around the gland can be tightened regularly to keep the gas from leaking. 2、Skeleton type: Skeleton type seal is generally a skeleton rubber oil seal, each group of oil seals by two or three J...

In the process of maintaining the Roots fan have those measures? About these measures Roots fan editorial take you to understand. 1, rotor shaft keyway damage Affected by the operating environment of the equipment and other factors, Roots fan often appear shaft head, keyway wear damage phenomenon, the problem appears, according to the traditional method to patch welding or brush plating after machining repair. However, the thermal stress generated by the high temperature welding can not be eliminated, easy to bend or fracture; brush plating is limited by the thickness of the coating, easy to peel off. 2, pump cavity corrosion protection The form of metal corrosion can be divided into two categories: comprehensive corrosion and local corrosion. The former occurs more uniformly on the surface of the fan, the latter only occurs in the local. For example...

Roots fan in the process of using the noise is inevitable, then for these noises we should how to deal with it? Roots fan editor to take you to understand. 1、Installation of muffler In general, the aerodynamic noise radiated from the fan air intake and exhaust than other parts of the radiation of the noise to be higher than 10-20dB (A), therefore, the control of fan noise, first of all, should be in the air intake and exhaust ducts on the installation of an appropriate muffler. The muffler is used on the fan, at present, both at home and abroad tend to use resistive muffler, and the muffler with larger volume and narrower muffling channel has been seldom used, of course, the muffler's selection, design and installation should be carried out according to the actual situation...
