　　羅茨鼓風(fēng)機(jī)原理與結(jié)構(gòu)簡(jiǎn)介

　　Answer: please refer to the table below for the model and parameter quotation of Roots blower produced and sold by our company! The prices in the table are reference prices. Recently, due to the continuous rise and fall of copper prices, the motor prices are very unstable. The specific prices are subject to the quotation of the day. If you need to order roots fans, please pick up the phone to make an inquiry as soon as possible!

　　Model, specification and parameter table of Roots blower:

　　Roots blower is a volume blower, which separates the air inlet by engaging a pair of rotors (there is clearance between the rotors and they do not touch each other). The rotor is driven by a pair of synchronous gears and moves in reverse to push the inhaled gas from the suction port into the * * * air port without internal compression. When the gas reaches the exhaust port, the pressure increases due to the reflux of high-pressure gas at the exhaust side, thus completing the gas transmission.

　　Roots blower model specification parameter table maintenance.

　　The operation and service life of the blower depend on correct and frequent maintenance, and pay attention to any signs of accidents. In addition to the general maintenance procedures, the following points should be noted.

　　1. Check the fastening of each part and whether the locating pin is loose.

　　2. There is no oil leakage in the blower body.

　　3. the blower body shall be free of scaling, rust and peeling.

　　4. pay attention to whether the lubrication and heat dissipation are normal and whether the lubricating oil quality is good. Always listen to whether the blower operates with noise and whether the unit operates under conditions that do not meet the requirements. Add grease regularly.

　　5. If the blower is overloaded and sometimes does not display immediately, pay attention to the increasing trend of inlet and exhaust pressure, bearing temperature and motor current, and judge whether the machine operates normally.

　　6. before disassembling the machine, measure the fitting dimensions of the machine, make records, and mark the parts to ensure that the original fitting requirements are maintained after assembly.

　　7. for new or overhauled blowers, the oil tank shall be cleaned and put into operation according to the use steps. It is recommended to replace all lubricating oils after 8 hours of operation.

　　8. The maintenance shall be carried out on time and recorded according to the specific use conditions. It is recommended to overhaul once a year and replace the bearings and related vulnerable parts.

　　9. It is recommended that the blower be repaired by the company or maintenance personnel.

　　Roots blower

　　Operating principle of Roots blower model specification parameter table.

　　Roots blower is a kind of volume blower, and the air volume conveyed is proportional to the number of revolutions. Three blade impeller absorbs and exhausts air three times every two impellers rotate. Compared with the two blade type, the gas pulsation is reduced, the load change is small, the mechanical strength is high, the noise is low, and the vibration is small. There are two three blade impellers on two parallel shafts. There is always a small gap between the wheel and the inner hole surface of the oval case and each impeller. As the impeller rotates at a uniform speed in the opposite direction, a certain amount of gas around the box and impeller is transmitted from the suction side to the discharge side. Each impeller is always kept in the correct phase by the synchronous gear and does not touch each other. Therefore, it can be widely used in various fields, without internal lubrication, simple structure, stable operation and stable performance.

　　The impeller and shaft are of integral structure. The impeller has no wear and tear. The fan has long-lasting performance and can operate continuously for a long time.

　　The structure is very compact.

　　Simple structure, excellent durability, longer service life than domestic fans and convenient maintenance and management due to the use of special bearings.

　　Due to the gear oil slinging device, there will be no oil leakage.

　　The models are complete and can be selected according to the purpose.

　　Precautions for fan installation.

　　1. The foundation shall be firm and the surface shall be flat, 10-25cm higher than the ground.

　　2. Sufficient space shall be reserved around the fan to meet the needs of maintenance and disassembly.

　　3. The working ambient temperature of the fan shall not exceed 40 ℃. If it exceeds 40 ℃, cooling measures shall be taken, otherwise the service life of the fan will be shortened.

　　2. The pipe shall be able to withstand the exhaust temperature and pressure. (try to use steel pipe)

　　3. The inside of the pipe shall be clean and free of foreign matters to prevent sundries from entering.

　　4. a check valve shall be installed on the pipeline to prevent the return high-pressure gas caused by fan reversing from entering the fan and damaging the fan. Note: the horizontal pipeline shall be installed with one-way valve.

　　5. When multiple fans operate in parallel, gate valves must be set on each pipeline (when one fan is repaired, the pipeline can be cut off).

　　6. exhaust valve shall be set on the pipeline to prevent the fan from starting with load. After no-load startup, the fan shall gradually close the exhaust valve. When operating with load, open the exhaust valve first, and then close the fan after confirming that the fan has no load.

　　Installation and use.

　　1. The fan should not be installed in places where people often go in and out to prevent injury and scald.

　　2. Fans shall not be installed in places with flammable, explosive and corrosive gases to prevent fire disaster, poisoning and other accidents.

　　3. According to the direction of air inlet and outlet and maintenance needs, appropriate and sufficient space shall be reserved around the foundation surface.

　　7. When conveying air medium, its dust content generally does not exceed 100mg/m3.

　　8. Precautions for operation and use.

　　(1) Check the connection tightness of all parts, bolts and nuts of the fan, the installation quality of all fasteners, positioning pins, air inlet and exhaust pipes, valves, etc.

　　(2) In order to ensure the normal operation of the blower, it is not allowed to bear external loads such as pipes, valves and frames.

　　(3) Check the correct quality of the blower and motor.

　　(4) Check whether the base of the unit is fully padded and whether the anchor bolts are fastened.

　　(5) Inject the specified brand of mechanical oil * * * into the oil tank, and the brand of lubricating oil is N220 gear oil.

　　(6) Check whether the motor steering meets the pointing requirements.
