What are the applications of Roots blower for sewage treatment?

For many people, sewage treatment is a tedious task. If roots blower is used in the process of sewage treatment, the purpose of clean sewage can be achieved. Now let's introduce the contents of roots blower in sewage treatment, let's get to know!

Roots blower for sewage treatment

Roots blower is a volumetric fan, and the air volume delivered is proportional to the number of revolutions. Roots blower is a 2-impeller type, with reasonable structure, strong versatility, convenient maintenance and other characteristics.

Roots blower is a three blade impeller type. The three blade impeller is sucked and exhausted by two impellers for three times every time it rotates. Compared with the two blade type, the gas pulsation starts to decrease, the load change is small, the mechanical strength is high, the noise is low, and the vibration is small.

Two three blade impellers are set on two parallel shafts, and appropriate small gaps are kept between the wheel and the inner hole surface of the oval case and between the three impellers. Since the impellers are rotating in the opposite direction at a constant speed, a certain amount of gas surrounded by the box and the impeller is transported from the suction side to the discharge side.

Each impeller is always kept in the correct phase by the synchronous gear, without touching each other, so it can be high-speed, without internal lubrication, and has simple structure, stable operation and stable performance.

What preparations should be made before starting Roots blower for sewage treatment?

(1) Check the installation quality of fasteners and locating pins.

(2) Check the installation quality of inlet and exhaust pipes and valves.

(3) Check whether the assembly clearance of the blower meets the requirements.

(4) Check that the coaxiality of the fan driving shaft of Roots blower and motor for sewage treatment shall not exceed 0.1mm, otherwise it will lead to vibration, oil leakage and other phenomena of the fan, which will affect the service life of the fan.

(5) Check whether the base of the component is fully padded and whether the foundation bolts are fastened.

(6) Before starting Roots blower for sewage treatment, lubricating oil shall be added to the main oil tank and auxiliary oil tank to 3mm/2mm of the center of the oil pointer. The lubricating oil used shall be 68 # machine oil in summer and 100 # machine oil in winter. The lubricating oil shall be replaced every three months.

(7) . Due to the pressure in the main and auxiliary oil tanks, the upper and lower oil plugs of the main and auxiliary oil tanks should be tightened, otherwise oil leakage will occur.

(8) . Supply water to the cooling part. The temperature of cooling water shall not exceed 25 ℃, and the cooling water volume shall be 10L/min.

(9) . Fully open the air inlet and outlet valves of the blower and turn the rotor, and pay attention to whether there is noise in each part.

(10) Check the rotation direction of the motor, which must conform to the direction shown on the steering label, otherwise the fan cannot exhaust normally, and the phenomenon of fan blade collision may also occur. When the water is aerated, the water will flow into the fan in the opposite direction, and the transported objects will be sucked into the fan during pneumatic transmission, leading to accidents.

How to maintain Roots blower for sewage treatment?

(1) Check the fastening of each part and whether the locating pin is loose.

(2) Whether there is water leakage and oil leakage inside the Roots blower body.

(3) . There shall be no scaling, rust and scaling inside the Roots blower body.

(4) Pay attention to whether the cooling condition of lubricating oil is normal, pay attention to the quality of lubricating oil, and often listen to the blower for noise.

(5) The overload of Roots blower is sometimes not displayed immediately, so pay attention to the increasing trend of inlet and exhaust pressure, bearing temperature and motor current, so that you can judge whether the machine operates normally.

(6) Before disassembling the machine, the matching dimensions of the machine shall be measured, recorded and marked on other parts, so as to ensure the assembly and maintain the original matching requirements.

(7) For new machines or overhauled Roots blowers, the oil tank should be cleaned and put into operation according to the operating procedures. It is recommended that all lubricating oil should be replaced after 8 hours of operation.

(8) For maintenance and overhaul, a reasonable maintenance system shall be formulated according to the specific use conditions, and shall be carried out on schedule and recorded. Under normal conditions, the unit is required to replace the lubricating oil after 1000 hours of operation, conduct minor maintenance or inspection once after 4000 hours, and conduct major overhaul once a year and replace relevant vulnerable parts.

(9) , faults and troubleshooting.

Now roots blower is used frequently and widely. If you encounter problems in the process of Roots blower, you can consult us in time.
