Roots blower The reason why the temperature is too high is to eliminate the problem in time: the oil in the fuel tank is too much, too thick and too dirty; The filter or muffler is blocked; The pressure is higher than the specified value; The impeller is excessively worn with large clearance; Poor ventilation, high indoor temperature and high inlet temperature; The working speed is too low, and the belt slips. When using Roots blower, the temperature of the inlet gas is not higher than 40 ℃, the working temperature of the bearing is not higher than 95 ℃, and the temperature of the lubricating oil in the fuel tank is not higher than 65 ℃ to ensure that no accident will occur under the applied temperature.
Maintenance and protection of Roots blower: the fan can be used for a long time at an ambient temperature not exceeding 40 ° C. When the temperature exceeds 40 ° C, the exhaust fan shall be installed to reduce the service life of the fan. When transporting air, natural gas, natural gas and other media, the dust content shall not exceed 100mg/m3.
1、 The two shaft drive mechanism is equipped with the same style and size end, which is meshed with two gears, so that the motor drive shaft is directly connected to the driven shaft to drive the gear in the opposite rotation direction. The revolution of each rotor can squeeze out twice the shadow volume of air, thus pushing the shadow volume of air 4 times a week for each rotating axis.
2、 The inlet and outlet arrangement of Roots blower should be reasonable: the bottom of the upper exhaust port (in the case of upper level), so you can use high-pressure gas to offset part of the rotor and shaft gravity, reduce the pressure of the bearing, and reduce wear. According to these conditions, when the temperature of the fan is high, proper cooling measures can be taken to ensure the working blower, because excessive temperature will lead to machine failure and unnecessary losses.
3、 The temperature of the oil tank of the blower may be too oily, too coarse, too dirty, or the filter or muffler may be blocked;
4、 The pressure is higher than the specified value; The impeller is excessively worn, the gap is large, the ventilation is poor, the indoor temperature is high, the running speed is too low, and the belt slips.
5、 The root cause can cause the difference between the high temperature fan gear end gear and the bad side caused by the high fan inlet temperature is too small, or it is caused by the fan
6、 In the power, steel, cement, paper making and other industries, and in the large-scale use of patented fan equipment, because the natural gas transmission medium contains many hard dust particles and acid gases, the flow components of these equipment are strongly corroded, especially the heart part, whose running speed is 160 meters per second, The speed is more worn than other parts. According to statistics, the life of the impeller made of ordinary or ordinary wear-resistant carbon steel 16Mn is only 6 months, and the shortest is only tens of days. Although various measures are taken for the worn surface, such as welding, spraying and coating, wear-resistant coating.
The solution is to adjust the oil temperature of ratchet gear box is too high. The solution is to check whether the oil cooling system is normal; Cleaning solutions for dirty oil, replacement of new gear oil for lubrication system and bearings, etc;
7、 If the resistance to entering the system is too high or the temperature is too high, the solution is to adjust the operation of the system; The worn clearance of the fan rotor increases the fan, so as to operate in the eddy current. The solution is to repair the rotor and adjust the clearance.
8、 Roots blower is divided into transverse and longitudinal. The horizontal roots blower is composed of two kidney shaped involute rotors (hollow or solid) and two parallel shafts in the case of ellipse. Cases can be divided into water cooling and air cooling, and there is no cooling device category.
The above is the reason why the temperature of roots blower is too high. I believe you know why the temperature of roots blower is too high after reading the above content. I hope it will help you.
