Oil change time and precautions of Roots blower for sewage treatment

Measures to reduce energy consumption of Roots blower for sewage treatment:

1. Select a reasonable installation position, reduce elbows, and make the water outlet face the pool.

2. Shorten the pipeline.

3. Expand the outlet pipe diameter.

4. The filter screen can be removed when the water inlet can be kept clean.

5. Adjust the axial clearance to prevent improper impeller ring and axial clearance. When using, adjust according to the factory instructions of the pump.

6. Timely remove pipe blockages. Remove the foreign matters left in the inlet pipe, impeller or flow passage of the guide housing.

7. Prevent the water pump from entering the air. If air enters the water pump, the water output will be reduced, and all sealing parts need to be inspected and maintained.

Sewage treatment measures for gear box inlet of Roots blower: If the cooling water pipe breaks, the fuel tank will enter the water. In this case, it is necessary to stop work in time. If the cooling water pipe is damaged, the condition is very serious. After parking, the fuel tank needs to be removed. inspect Whether the gear of the fan is damaged.

In this case, only disassembly and repair can be carried out. After the water cooling pipe is repaired, test and reload it to check whether the fan can work normally.

The idle fan water tank is filled with water. If the fan is idling, the fan gearbox is full of water due to human reasons. You can open the drain hole at the bottom of the water tank to drain the lubricating oil and water inside, and then put it for several days. Evaporate the water inside, and then wash it with lubricating oil. After filling the fuel tank with lubricating oil, the pulley moves. Try the operation to see the effect. If there is any problem, please stop in time.

Oil change time and precautions of Roots blower for sewage treatment:

The disassembly drawing of Roots blower is a positive displacement fan. In the space sealed by the shell and the wall plate, there are two trivanes that can rotate relatively. Because each impeller adopts an involute or cycloidal housing. The three blades of each impeller are the same, while the two impellers are the same, which reduces the processing difficulty. Numerical control equipment is used in the processing of impeller. When two impellers are at the same center distance, no matter where the two impellers rotate, a small clearance can be maintained, so that the gas leakage is within the allowable range.

Since the clearance between impeller and impeller, impeller and housing, impeller and wall plate is very small, the two impellers rotate in opposite directions, so the air inlet forms a vacuum state, and the air enters the lower air inlet chamber under the effect of atmospheric pressure. Then, each of the two impellers forms a sealing chamber with the wall plate and the housing. During the rotation of the impeller, the air in the intake chamber continuously enters the exhaust chamber through a sealed chamber formed by two blades, and because of the exhaust, the impellers in the cavity mesh with each other to squeeze the two blades. Air between. The continuous operation of air continuously flows from the air inlet to the air outlet.

The sequence of gear oil replacement in the disassembly drawing of Roots blower for sewage treatment: first inject gear oil, then inject new gear oil, once: 100 hours after starting operation, twice: 300 hours after starting operation, and then replace every 1000 hours.

The oil quantity of each model of Roots blower can be checked at any time on the gear side oil mirror, and the oil level between neutral wires can be maintained during shutdown. If the oil level is lower than the middle position, add lubricant in time. If the oil level is higher than the middle position, oil leakage will occur.

Disassembled drawing of Roots blower for sewage treatment After gear oil is injected, the remaining gear oil should not be directly exposed to the outside world to prevent other pollutants from entering the barrel and causing oil pollution. Secondly, keep the oil away from the fire source and place fire extinguishing equipment. After use, tighten the cover to keep the drum secure. The new oil and waste oil shall be placed separately, and the container filled with waste oil shall not be filled with new oil to prevent pollution.
