Reasons and Solutions for Fragile Belt of Roots Blower

图片
1. Reasons for easily broken belt of Roots blower: 1. First of all, consider the high speed and high temperature of Roots blower. 2. The distance between the head and motor of Roots blower is too large and the belt is tight. 3. The belt does not match the V groove of the pulley, so it can not withstand the load fracture after wearing. 4. Active pulley and driven pulley are not parallel, resulting in serious friction between belt and groove on one side, and can not bear load fracture after wear. 5. Heavy load, long-term overload operation of belt is easy to break. 6. Roots fan nose and motor pulley are not concentric, different axes. 7. Belt quality problems. 2. Measures to prevent the belt of Roots blower from breaking. 1. Roots blower must start without load before running. After starting, it should be loaded. After running, it can generally avoid triangular belt breaking. 2. The pulley between the motor and the fan should be parallel, which is a key point. If not para...

Single screw vacuum pump five sealed basic components

图片
Functions and requirements of the five main sealing elements of a single screw vacuum pump: End seal pair (static and moving ring). The function of the sealing pair of the end face is to make the sealing surface tightly fit and prevent the leakage of medium. It requires the static and moving ring to have good wear resistance, the moving ring can move flexibly in axial direction, automatically compensate the wear of sealing surface, make it fit well with the static ring; The static ring is buoyant and ACTS as a buffer. Therefore, the sealing surface requires good processing quality to ensure the sealing pair has good fitting performance. Elastic element (spring, bellows). It mainly plays the role of compensation and buffering, the requirement always maintain enough elasticity to overcome the inertia of the auxiliary seal, the friction of the transmission part and the moving ring, etc., to ensure the good fitting of the sealing pair of the end face and the tracking of th...

Reasons for Axis Breakage of Water Ring Vacuum Pump and Corresponding Measures

图片
Axis Breakage of Water Ring Vacuum Pump: After 2 years of use, water ring vacuum pump will present the phenomenon of excessive noise, excessive starting current, remarkable decrease in pumping capacity and vacuum degree. It is found that the scale inside the pump body is severe after the technical staff of our company disassembled and inspected. The reason for scaling is that the water contains calcium, magnesium and other carbonate substances. When the pump is heated and heated, its solubility decreases, and molecule-bound deposits form scales. What measures should be adopted to avoid axle breakage? Water ring vacuum pump Through the analysis of the causes of shaft breakage of water ring pump, the following corresponding measures are adopted. 1. Revamping the original process equipment to reduce the content of impurities in acetylene gas trap: At the same time, the large well water of water ring vacuum pump is changed into circulating water to reduce the hardness of wat...
