Low noise sewage treatment Roots blower

Low noise sewage treatment Roots blowerworking principle

The motor drives the active rotor to rotate, and the driven rotor rotates in the opposite direction through the synchronous gear. When the rotor is engaged, a sealed chamber is formed between the casing and the rotor, and the gas is gradually compressed and pushed to the exhaust port as the rotor rotates. The three bladed rotor design divides the compression process into stages, reducing airflow impact and achieving continuous and smooth airflow output. Due to the absence of internal compression process, its exhaust pressure is determined by back pressure, making it suitable for scenarios that require constant flow gas supply.

Application field

Municipal sewage treatment: The aeration of the biochemical tank in urban sewage treatment plants provides continuous oxygen for the activated sludge process, accelerating the decomposition of organic matter.

Industrial wastewater treatment: Wastewater treatment stations in industries such as chemical, pharmaceutical, and food processing enhance microbial degradation capabilities through aeration for high concentration organic wastewater or toxic substance wastewater.

River ecological restoration: In the treatment of black and odorous water bodies, aeration is used to increase dissolved oxygen in the water, improve the anaerobic environment of sediment, inhibit the reproduction of anaerobic bacteria, and restore water ecological balance.

Sludge treatment: In sludge concentration tanks or digestion tanks, air flow agitation is used to prevent sludge from settling and clumping, promoting sludge granulation and stabilization.

Low noise sewage treatment Roots blowerInstallation precautions:

1. Do not install the fan in areas that are prone to producing corrosive gases such as organic solvents and coatings to prevent fires and poisoning.

2. Do not place the fan in places where people often pass through and children often enter and exit to prevent injury and burns.

3. The indoor temperature of the Roots blower for sewage treatment should be below 40 ° C. If the temperature exceeds 40 ° C, the lifespan of the blower and motor will be greatly shortened. Please set up a ventilation fan to ensure that the room temperature is below 40 ° C. When the temperature is below 0 ° C in winter, it should be noted that the gear oil will solidify and the temperature will rise after a period of time.

4. The foundation should be strong, the surface should be flat, and the foundation should be higher than the ground.

5. The space around the fan should meet the requirements for fan disassembly and maintenance.

When installing fans outdoors, please install a rain shelter.

Maintenance standard for Roots blower for sewage treatment:

The vertical tolerance of bearings and rotors shall not exceed 0.05 mm.

When assembling the rotor, the deviation of the parallelism between the two ends of the newspaper must not exceed 0.02mm, and the deviation of the parallelism between the end face and the plate surface must not exceed 0.05mm. When the inlet and outlet directions of the fan are constant with the main shaft position, the space of the rotor pressure angle is constant. Adjustments must be made at two positions on the rotor horizontal line at a 45 ° angle. The rotor space varies for different models.

3. It is necessary to check the dynamic and static balance of the rotor.

4. The rotor must not have defects such as water bubbles and pores.
