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...

Inspection methods of hidden safety hazards of water ring vacuum pump

图片
In daily use, it is important for product quality. Water ring vacuum pump must be shut down in a planned way. After that, we should also pay attention to the following circumstances in accordance with the management regulations, when the pump shutdown is required, the person in charge of the pump shutdown unit must pay attention to four hours in advance for the relevant shutdown approval procedures; point of view, when the power department at a higher level, the company or the line maintenance failure needs to shut down. In addition, when the line in the mine fails, it will be shut down due to maintenance; when the water ring vacuum pump fails or needs to be shut down due to regular switching; when the circulating pool needs to replace the water source; when the welding of nearby drainage pipeline and the replacement and installation of other ancillary devices; for this reason, the vacuum pump needs to be shut down because of other reasons. When special circumstances or ...

Reasons for High Temperature of Stainless Steel Vacuum Pump Motor

图片
Everyone knows that stainless steel vacuum pump is a kind of equipment which obtains vacuum by mechanical, physical, chemical or physical chemical methods. It is used for vacuum extraction at the start of the unit. Normally, it is used to extract the unconsolidated gas in the condenser. Every summer, the temperature of the motor will exceed the limit, while the motor will be high for a long time. Temperature operation will cause insulation aging and shorten its service life. The reason why the temperature of stainless steel vacuum pump motor is too high is introduced below. 1. Stainless steel vacuum pump fan speed is low, wind pressure, air volume is small. 2. The number of fan blades is small and the amount of air generated is small. 3. Stainless steel vacuum pump motor has high power, high working current and high calorific value. Fourth, the motor has dust and oil pollution, which reduces the heat dissipation capacity. Fifth, the bus voltage of the stainless steel vac...
