How to determine the steering of the vertical roots blower motor

Dear, I am glad to answer for you, the rotation direction of the roots blower shall not be reversed. When installing and using, it is necessary to check the steering of the roots blower, the steering of the roots blower must rotate according to the direction indicated by the arrow, if there is an error in the direction of rotation, it will affect the exhaust air of the roots blower, at this time the roots blower is in the wrong operating state, in the case of reverse rotation, the loss of the equipment is caused, and the service life of the fan is damaged. 2. The installation of the fan is higher than the ground The installation and use platform of the roots fan must be higher than the ground, if it is lower than the ground, some exhaust gas and dust may be inhaled, and the working efficiency of the fan will also be reduced.

3. The switch is placed in a position that is easy to operate The switch of the equipment should be around the roots blower equipment, and if there are some abnormal phenomena in the process of use, the power can be cut off in time for inspection. Here we also want to remind users that when using the roots blower for trial operation, it is necessary to be equipped with two staff, one is responsible for opening and balancing the land customs control, and the other is responsible for observing the operation of the equipment, and if there is a problem, the power can be cut off and controlled in time. 4. The conveying channel needs to be sealed When transporting gas, the pipeline should ensure good sealing, and there should be no air leakage and deflation in the middle, which will reduce the working efficiency of the roots blower and cause the loss of power resources.

5. Add lubricating oil in time The addition of lubricating oil can reduce the friction loss between spare parts and improve work efficiency.

Summary. The steering of the roots blower is very important, the judgment is not correct during installation, and it is easy to burn out the motor when it is installed. 1. The belt drive arrow will have an indicator arrow on the belt guard of the roots blower, and the rotation direction of the roots blower impeller can be determined through the above instructions.

The direct drive also has a linkage shaft protective cover, and there is also an arrow with a fan drive on it, and the direction of rotation of the direct drive fan is easier to identify. 2. There is a certain difference between the inlet muffler and the outlet muffler through the muffler, the inlet muffler is the direction of air intake, and the rotation direction of the roots blower impeller can also be determined by judging the inlet. 3. Disassembly judgment If the roots blower can be disassembled tentatively, the rotating belt can clearly see the rotation direction of the impeller, but this method is more troublesome and requires certain professional knowledge.

The rotary roots blower is very important, the installation is not correct, and it is easy to burn out the motor and bury it, so today I will introduce you to a few simple methods! 1. The belt drive arrow will have an indicator arrow on the belt guard of the roots blower, and the rotation direction of the roots blower impeller can be determined through the above instructions. The direct drive also has a linkage shaft protective cover, and there is also an arrow with a fan drive on it, and the direction of rotation of the direct drive fan is easier to identify.

2. There is a certain difference between the brightness resistance of the imported muffler and the outlet muffler through the muffler, the inlet muffler is the direction of air entry, and the rotation direction of the roots blower impeller can also be determined by judging the inlet. 3. Disassembly judgment If the roots blower can be disassembled tentatively, the rotating belt can clearly see the rotation direction of the impeller, but this method is more troublesome and requires certain professional knowledge.

Will the roots blower damage the blower due to the backflow of water?

Yes. This can lead to internal motor failure.

Okay pro. Is it a forward rotation towards the motor?

The arrow points to a positive position.

Open-type, roots blower motor has a large vent on the outside, good heat dissipation conditions, and is cheap, but dust, iron filings or oil are easy to invade the inside of the motor, so this form of motor can only be used in a dry and clean working environment. Closed type, roots blower motor is divided into three types: self-cooled, forced ventilation and closed type. The first two types of motors with structures, moisture and dust are not easy to enter the inside of the motor, which can prevent water droplets and other debris from splashing from any direction, and are suitable for various places with moisture, dust, wind and rain erosion, easy to cause disasters, corrosive steam and gas.

Closed motors are generally used in water, and fans are rarely used. Protective type, the vent of the roots blower motor is facing downward, and there is a protective net to cover, and the ventilation and cooling conditions are better. It can generally be drip-proof, rain-proof, splash-proof, and prevent external debris from falling into the motor from the direction of less than 45 ° angle with the vertical direction, but can not prevent the invasion of moisture and dust, so it is suitable for relatively dry, dust-less, non-corrosive and high-quality gas places.

Explosion-proof type, made of flameproof type, increased safety type, positive pressure type and non-spark type on the basis of closed structure, suitable for hazardous environments with flammable gas and air mixtures, such as oil depots, coal loss stations and mines and other sock town places, explosion-proof ventilators are used in this type of motor.

The inlet and outlet of the roots blower are determined, how to rotate the motor.

Hello dear and happy to answer your <>

Kiss completely open the inlet roots blower inlet and outlet to determine how to rotate the motor control valve, outlet control valve and bypass pipe; Check whether the air filter at the air inlet is unobstructed and whether the filter inlet is fully open; Check whether the pipes, valves, mufflers and air filters are supported firmly, and there shall be no load force on the casing to check whether the lubricating oil is good and whether the model is appropriate, the depth of the lubricating oil layer should reach 3 5 cm above the specified oil line, and whether the cooling water system is unblocked; Toggle the coupling, check whether the impeller transfer is flexible, and whether there is friction collision; Check whether the connection of each part is good and whether there is looseness; Remove the surrounding debris and keep the fan free of debris within two meters; Check whether the electrical part and the liquid fracturing step-down starting equipment are in good condition; Check whether the maintenance tools are complete and whether the fire extinguishing equipment is sufficient and complete. When the outlet pressure of the roots blower is higher than the operating pressure, the outlet valve is gradually opened, and the door is brightened to adjust to the required flow rate, so that the pump can operate normally. Check the motor current, such as the roots blower should be stopped for inspection when the motor is overloaded when the roots blower is running at the rated flow rate.

During the operation of the environmental protection roots fan, you should always check whether the indicated value of the pressure gauge and ammeter is normal, check whether the bearing temperature is normal, check whether there is vibration and noise and other abnormal conditions, I hope this service can help you, you can click on my avatar to follow me, and if you have any questions in the future, you can consult me again, and look forward to serving you again. Wishing you well; Happy life, everything goes well [warm] [warm].
