Roots fan manufacturing belongs to the fan industry in the general machinery manufacturing industry

Roots fan manufacturing belongs to the fan industry in the general machinery manufacturing industry. It is driven by national policies and the needs of downstream industry development, and has good future growth. At the same time, the domestic fan industry is low in concentration, and domestic companies in related industries have a broad future market space. There is a lot of room for upgrading and replacing imports.

Correct maintenance and maintenance make the fan long service life

The fan gear adopts 20CrMnTi after carburizing treatment, grinding process, the accuracy is up to five, and the tooth surface is more wear-resistant. The bearing adopts imported double-row roller bearings with large carrying capacity. Therefore, the service life of the fan is increased. The fan output air is clean. The fan adopts a special structure design to prevent oily substances from entering the casing, so the output air does not contain any oil.

Fans can save energy and develop high-efficiency products is the key

Energy-saving wind turbines are the key to the development of high-efficiency products. Statistics show that the electricity consumption of wind turbines in use in the country accounts for about 10% of the country's total power generation. Among them, the electricity consumption of wind turbines used in metal mines accounts for the total electricity consumption of mining 30%; the power consumption of fans used by the iron and steel industry accounts for 20% of its total production power; the power consumption of fans used by the coal industry accounts for 17% of the total power consumption of the national coal industry. Therefore, for the fan industry, How to produce more energy-saving and environmentally friendly fan products is an issue that requires great attention.

Characteristics of Roots Blower

Roots blower is a positive displacement blower, and the air volume delivered is proportional to the number of revolutions. Each time the three-blade impeller rotates, the two impellers suck and exhaust three times. Compared with the two-leaf type, the gas pulsation is small, the vibration is also small, and the noise is low. The impeller on the 2 shafts of the fan and the inner hole surface of the elliptical shell, between the end face of the impeller and the front and rear cover of the fan, and between the fan impeller always maintain a tiny gap. Driven by the synchronous gear, the downwind flows from the fan inlet along the inner wall of the shell Delivery to the discharge side.

Causes and solutions of insufficient fan air volume

Causes and solutions caused by insufficient air volume of the fan 1. The inlet filter of the Roots blower is blocked: clean the imported filter 2. No lubricating oil: check the oil supply system and replenish the oil volume 3. Poor lubrication: clean the oil filter and drip Grease nozzle 4. Belt slip: adjust belt tension 5. Pipe air leakage: repair the pipe 6. Pipe is too long: reset the pipe

How to turn on and off Roots blower?

How to turn on the Roots blower? First check that the fan environment is turned on and the instrument and electrical equipment are in good condition (including normal three-phase power and no phase loss). Check if the fan lubricant is in the half of the liquid level mirror. Open the vent valve and outlet valve of the fan. Turn on the fan. After the fan is running normally, slowly close the vent valve, at this time the fan pressure gauge rises to 0.04-0.05Mpa.

Roots blower must be maintained and maintained in a correct and timely manner

Maintenance and overhaul should be based on the specific conditions of use to formulate a reasonable maintenance system, carried out on schedule, and keep records, it is recommended to overhaul once a year, and replace the bearings and related wearing parts. Before disassembling the machine, measure the matching dimensions of the Roots blower, make a record, and mark the parts to ensure that the original matching requirements are maintained after assembly.

Operating rules of Roots blower

Roots blower should adjust the air volume of the blower according to the oxygen demand of the aeration tank. When abnormal phenomena such as sudden power failure occur in the fan, water and oil cooling system, immediate measures should be taken to ensure that the fan does not malfunction.
