roots rotary lobe blower
Roots rotary lobe blower
Roots blower is a volumetric fan, with impeller end face and front and rear end covers of the fan. The principle is a rotary compressor that uses two blade-shaped rotors to move relative to each other in the cylinder to compress and transport gas. This type of blower has a simple structure and is easy to manufacture. It is widely used in aquaculture oxygenation, sewage treatment aeration, cement transportation, and is more suitable for gas transportation and pressurization systems in low-pressure situations. It can also be used as a vacuum pump.

Roots rotary lobe blower manual
- 1.Usage requirements:
- (1) The inlet air temperature is not greater than 40°C
- (2) The content of solid particles in the gas shall not be greater than 100 mg/m2, and the largest particle shall not be greater than half of the assembly gap;
- (3) The bearing temperature does not exceed 95°C;
- (4) The lubricating oil temperature does not exceed 65°C;
- (5) The opening pressure range specified on the sign shall not be exceeded.
- 2.Preparations before startup:
- (1) Check the installation quality of each fastener and positioning pin;
- (2) Check the installation quality of intake and exhaust pipes and valves;
- (3) Check whether the base of the unit is fully padded and whether the anchor bolts are tightened;
- (4) Inject the specified brand of lubricating oil into the gear box to the driving side of the oil mark position and inject the specified grease in sufficient quantity;
- (5) Open all the blower inlet and exhaust valves, turn the rotor, and listen carefully for any abnormal noises from various parts;
- (6) For fans with water cooling requirements, the water temperature should not be higher than 25°C.
- 3.No-load test operation of the fan:
- (1) Newly installed or overhauled fans should undergo no-load test operation;
- (2) No-load operation means putting into operation with the intake and exhaust valves fully open;
- (3) There is no abnormal smell, smoke, collision or friction sound, and the radial vibration of the bearing part is not greater than 6.3mm/s;
- (4) Run with no load for about 30 minutes. If the situation is normal, it can be put into operation with load. If abnormal operation is found, stop the machine immediately for inspection. After troubleshooting, it still needs to run with no load.
- 4.Continuous operation under normal load:
- (1) It is required to gradually and slowly increase the voltage and bring the load up to the rated load. It is not allowed to adjust to the rated load at one time;
- (2) During normal operation of the fan, it is strictly prohibited to completely close the engine and exhaust valves; nor is it allowed to operate overloaded;
- (3) Due to the characteristics of the fan, it is not allowed to directly backflow the exhaust gas for a long time, so cooling measures must be taken;
- (4) The blower should not stop suddenly under full load to avoid damage to parts.
What are roots blowers used for?
- 1.Used for ventilation: Roots blowers can quickly transport gas from one area to another. Indoor ventilation is relatively common, so that good air quality and a comfortable working environment can be maintained. .
- 2.Used for waste gas emission: In some industrial processes, a large amount of waste gas will be produced, which needs to be discharged, otherwise it will cause environmental pollution. The Roots blower can quickly discharge these waste gases to ensure the safety of the production process.
- 3.Used for pressurized transportation: In some industrial fields, such as water treatment, paper manufacturing, power generation, etc., compressed air needs to be transported to drive equipment and production processes. Roots blowers can compress gas and transport it to the required area.
- 4.Use in other fields: Roots blowers can also be used in sewage treatment, dust collection, paint spraying, food processing, equipment and other fields, and their value is relatively wide.
