Multi-stage centrifugal blower: the start-up operation process of multi-stage centrifugal blower

To use a multi-stage centrifugal blower, we must first learn to start it, because it is basic. However, there are many tricks, if you master it, you can start the machine smoothly, otherwise it will damage the machine. In order to let everyone have the correct operation method, I will introduce it in detail below.

Multi-stage centrifugal blower: the difference between multi-stage centrifugal blower and single-stage

The single-stage and multi-stage centrifugal type blowers are a kind of speed regulating fan, that is, during the rotation of the working wheel, the speed of the gas increases due to the action of the rotating centrifugal force and the diffusion flow in the working wheel, and then the diffuser is used to convert the speed energy into pressure energy. The specific differences between the two are:

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

Roots blower manufacturing belongs to the general machinery manufacturing industry in the fan industry, driven by national policies and downstream industry development needs, the future growth is good; at the same time, the domestic fan industry concentration is low, the domestic related industries of the company's future market space is broad, product upgrades to replace the import space is large.

Proper maintenance and maintenance makes the fan long service life

The fan gear adopts 20CrMnTi carburizing treatment, grinding processing, precision up to five, the tooth surface is more wear-resistant. The bearing adopts double-row roller imported bearing with large carrying capacity. The service life of the fan is thus increased. The fan output air is clean. The fan adopts a special structural design to avoid oil substances entering the casing, so the output air does not contain any oil.

Fan energy saving has great potential to develop efficient products is the key

The development of high-efficiency products is the key to energy-saving fans. Relevant statistics show that the electricity consumption of fan products in use in the country accounts for about 10% of the total power generation in the country. Among them, the electricity consumption of fans used in metal mines accounts for 30% of the total electricity consumption of mining in the country; the electricity consumption of fans used in the iron and steel industry accounts for 20% of the total electricity consumption of its production; and the electricity consumption of fans used in the coal industry accounts for 17% of the total electricity consumption of the coal industry in the country. 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 volumetric fan, the air volume delivered is proportional to the number of revolutions, and the three-blade impeller is sucked and exhausted 3 times by 2 impellers every time it rotates. Compared with the two-blade type, the gas pulsation is small, the vibration is small, and the noise is low. The impeller on the two shafts of the fan and the inner hole surface of the oval shell, the end surface of the impeller and the front and rear end covers of the fan and the impeller of the fan always maintain a small gap. Driven by the synchronous gear, the downwind is transported from the air inlet of the fan along the inner wall of the shell to the discharge side.

Causes and Solutions of Insufficient Air Volume of Fan

Reasons and solutions caused by insufficient air volume of the fan 1. The inlet filter of the Roots fan is blocked: clean the inlet filter 2. There is no lubricating oil: check the oil supply system and supplement the oil quantity 3. Poor lubrication: clean the oil filter and the oil dripping nozzle 4. Degree belt slippage: adjust the belt tension 5. Pipe leakage: repair the pipe 6. The pipe is too long: reset the pipe

How to open and close the roots blower?

How to open the Roots Blower? First, check the opening of the fan environment and the good condition of the instrument and electrical equipment (including normal three-phase power and no phase shortage). Check whether the fan lubricating oil is in half of the liquid level mirror. Open the vent valve and outlet valve of the fan. Turn on the fan. After the normal operation of the fan, slowly close the vent valve, and the pressure gauge of the fan rises to 0.04-0.05Mpa.

Roots blower to correct, timely maintenance and maintenance

Maintenance and overhaul should be based on the specific use of the development of a reasonable maintenance system, on schedule, and make a good record, it is recommended to overhaul once a year, and replace the bearings and related wearing parts. Before disassembling the machine, the matching dimensions of Roots blower shall be measured and recorded, and the parts shall be marked to ensure that the original matching requirements are maintained after assembly.

Operating Procedures for Roots Blower

When using the Roots blower, the air volume of the blower should be adjusted according to the oxygen demand of the aeration tank. In case of abnormal phenomena such as sudden power failure of the fan and water and oil cooling system, measures shall be taken immediately to ensure that the fan does not fail.
