Use of Roots blower, the role of Roots blower in gas transportation

Roots blower is a double blade wheel synchronous compression machine. Each type of rotor is supported by two bearings. A pair of synchronous gears are used to keep the relative position of the two rotors constant. It is a positive displacement blower with forced gas transmission characteristics. As a rotary machine, Roots blower has relatively stable working characteristics. There are small gaps between the rotor and rotor, between the rotor and the pump body, and between the rotor and the side cover. Therefore, there is no friction and no contact wear in the working chamber. There are six suction and exhaust processes in a week of operation, and the volumetric efficiency is high. Simple structure, convenient use and maintenance, no need for internal lubrication, and the conveyed medium is oil-free. The support of the pump rotor adopts a reliable clearance elimination structure. The rotating parts are carefully balanced and high-precision helical gears are used. Therefore, the operation is stable, the noise is low, the use is more reliable, and the pump can operate for a long time under high pressure difference.

The output frequency of the frequency converter is controlled by the pressure signal measured by the pressure sensor installed on the previous gas pipeline, so that the speed of the motor changes with the pressure of the gas collector. Because the shaft power is proportional to the cubic speed, while the output of active power is cubic, the energy consumption of the motor is greatly reduced, and the automation degree of the gas transmission link is improved.

The frequency converter can work in two states: automatic (that is, the output frequency is adjusted by the pressure signal) and manual (the working frequency is set manually), and it has the mutual switching function of auto decompression startup and frequency converter startup. When one of the working modes is in maintenance or has faults, it can be manually switched to the other, It will not affect normal production.

Use of Roots blower

The user should submit the type of fan (including blower, fan, Roots fan, axial flow fan, etc.), and provide the inlet and outlet dimensions and air volume of the fan. Generally, the fan silencer is installed at the outlet, and the fan silencer should be comprehensively treated, that is, the silencer and the sound insulation room should be installed together.

The enclosure of fan muffler is carbon steel, and the internal materials are divided into aluminum plate and stainless steel, which can be selected by the user according to the cost. The user should provide the hourly emission, exhaust outlet size, exhaust temperature and pressure. The exhaust muffler is generally of anti spray resistance composite type. Its shell is generally made of carbon steel, and its connecting pipe and interior are made of stainless steel. It has the advantages of wide noise elimination frequency band, wide application range, large noise elimination amount, high temperature and pressure resistance, and is not afraid of water vapor and oil mist. Small hole injection muffler can also be used, which is generally made of all stainless steel.

The intake chamber and exhaust chamber are isolated from each other, and the gas in the body is sent from the intake chamber to the exhaust chamber by means of the reverse rotation of the two rotors, so as to achieve the function of blowing. Since there are very small gaps between impellers, between impellers and casing, and between impellers and wallboard, there is no need to inject lubricating oil into the cylinder or auxiliary equipment of oil-gas separator during operation. Since there is no mechanical friction between rotors, it has the advantages of high mechanical efficiency, less overall heating, long service life, etc. Roots blower is a relatively sophisticated equipment. Pay attention to the cleaning and replacement of the inlet filter during normal maintenance. The indoor air shall be clean and unblocked, and lubrication shall be ensured.

I believe that after reading the above content, you should also understand the role of Roots blower in gas transmission. I hope it will help you.
