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...

Cautions for Compressed Air of Water Ring Vacuum Pump

图片
Below is a brief introduction of the water-ring vacuum pump compressed air matters needing attention, hoping to help users, but also let the friends who want water-ring vacuum pump get some common understanding, together with a simple understanding: When using vacuum pump as compressed air, water-ring vacuum pump can be selected. When choosing water-ring vacuum pump as compressed air, attention should be paid to the correct selection. If the selection is improper, the motor of the water ring pump will be overloaded and burned down. If the water ring pump is used as compressed air, because the external air is continuously sucked into the vacuum pump and can not be discharged in time after compression, the water ring pump will be blocked by discharging so that the internal pressure of the water ring pump will be too large, resulting in motor overload. In order to effectively prevent this kind of situation, it is necessary to select the corresponding standard electric motor...

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...
