Roots blower It is a volume rotary blower. Its biggest feature is that when the pressure is adjusted within the allowable range, the flow changes little, the pressure selection range is wide, and it has the characteristics of forced gas transmission. The medium does not contain oil during transportation. Simple structure, convenient maintenance, long service life and low vibration of the whole machine.

Roots blower is a positive displacement blower, which can be used as a vacuum auxiliary for suction. Two rotors rotate in opposite directions to achieve the effect of pressing or expelling gas. Both rotors are fixed on a set of synchronous gears, so when rotating, there is a quite small gap between the cylinder and rotor to prevent them from contacting each other. Generally, the gap is about a few tenths of a millimeter. Since they do not rub against each other, they can run at high speed to obtain large air volume or exhaust speed. This product is widely used in metallurgy, chemical industry, light industry, building materials, mines, textiles, pneumatic conveying, sewage treatment, ceramics and other industrial sectors. Grease.

What are the operating conditions of Roots blower?

(1) The inlet gas temperature is not more than 35 ℃.

(2) The content of solid particles in the gas shall not be greater than 100m3, and the maximum size of particles shall not be greater than the minimum working side gap specified in Table 2.

(3) The coal tar index of gas shall comply with the provisions of TJ28-78 Urban Gas Code Design.

(4) The maximum bearing temperature shall not exceed 85 ℃.

(5) The maximum lubricating oil temperature shall not exceed 65 ℃.

(6) The pressure indicated by the pressure gauge on the fan shall not exceed the pressure rise range specified on the label, otherwise, it is necessary to stop the machine to check whether the air inlet in the system is blocked, whether the air inlet and exhaust valves are all closed, whether the static and moving parts in the fan have friction and other problems, and take corresponding measures.

Do you know the installation environment requirements and operating conditions of Roots blower?

Maintenance and overhaul:

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

(2) Check the engine body frequently for oil leakage;

(3) Pay attention to whether the lubrication is normal, pay attention to the amount of lubricating grease, often listen to whether there is noise in the operation of the fan, and pay attention to whether the unit operates under the specified conditions;

(4) Lubricating oil (grease): medium load industrial gear oil (brand 220, kinematic viscosity 198-242mm2/s40 ℃, flash point ≥ 200 ℃); The grease is butter (the penetration of synthetic lithium base grease is 220250, and the dropping point is ≥ 190 ℃). After 200 hours of operation, change the oil and grease for the first time, and change the oil and grease for the second time after one month of operation. In the future, the oil (grease) shall be replaced according to the service environment and oil (grease) quality. It is recommended to replace it every three months;

(5) Check the air inlet gas filter frequently, clean or replace the filter section in time;

(6) The overload of the blower is sometimes not displayed immediately, so pay attention to the increasing trend of inlet and exhaust pressure, bearing temperature and motor current to judge whether the blower operates normally;

(7) Before disassembling and assembling the machine, measure the size allocated to the machine, make records, and mark the parts to ensure that the original matching requirements are maintained after assembly;

(8) After a new machine or overhaul, the oil tank should be cleaned and put into operation according to the use steps. It is recommended to replace all lubricating grease after 8 hours of operation.

I believe that after reading the above, you should also know the operating conditions of Roots blower. I hope it will be helpful to you.
