Key Questions to Ask When Ordering Roots Blower Supplier

Powder conveying blower manufacturer: what is Roots blower

If you want to learn more, please visit our website Benyuan.

The principle of Roots blower is:The impeller is rotated directly driven by the motor. In the operation of the air convection and pressure difference, the machine gas inhalation and compression (vacuum pump) and then discharged; when the volume of the discharged gas is greater than the entrance of the gas, that is, along the axial direction into the suction chamber again for compression and improve its temperature and air pressure. This repeated cycle to achieve continuous pumping or exhaust process, so as to achieve the purpose of conveying media. Due to the special simple and compact mechanical structure, easy to install, reliable operation and long service life, no wearing parts and easy maintenance and other advantages, and is widely used in chemical fertilizers, food, pharmaceutical, building materials, electric power and other industrial fields. According to different uses can choose explosion-proof type ordinary type and explosion-proof type three types.

Powder conveying blower manufacturers: what are the precautions for purchase

1'Before buying should first understand the technical indicators of the product

Such as flow Q / Hm3 / h, export static pressure P0 / P1MPa, efficiency E2 / η = 1- 0.9, inlet dynamic pressure Pa = 10 - 20Kpa.

2, according to the product samples to provide the parameter value to select

For example: if you need to match the cooling tower, specify the air inlet size D2mm × D3 mm or outlet size D4mm × D5mm, etc.. Should also provide the corresponding piping connection diagram.

3, check the appearance of quality

Including the parts of the damage, deformation and paint peeling and other conditions, such as abnormalities should be promptly notified to the manufacturer to replace parts or return processing. (Note: due to different manufacturers of different production process levels resulting in product quality differences.)

4, test run

Turn on the power switch to start the machine rotation for 2-3 minutes to observe whether there is a murmur or other abnormal phenomena, if there should be immediately shut down for inspection and troubleshooting before restarting the test.

Powder conveying blower manufacturers: Roots fan to pay attention to what matters?

(1)Regular maintenance and repair is required, in order to ensure safety and longevity of service life, it is necessary to regularly clean the filter and other parts to remove dust and dirt to prevent clogging of the filter.

2)Do not overload the filter.

3)Do not stay under high temperature for a long time.

4) Avoid being close to the heat source.

5)Prohibit starting with empty vehicle

6)Strictly prohibit lifting with loads

7)Reverse rotation at high speed is not allowed

8)Do not frequently start and stop the blower

9)When oil leakage is found, it should be repaired in time.

10)Cut off the power supply line when it is not used for a long time.

What do I do if my blower does not turn?

The first step is to examine the driver and see if the driver components such as the motor or engine are in proper working condition. If the driver is operational, you need to turn off, or de-energize, the system and lock out the power supply.

Follow these steps to open up the inside of the blower:

• Turn off the system and lock out the power supply.
• Remove any filters, silencers or fittings that block access to the inlet and discharge.
• Remove belts or coupling guards so you can turn the unit shaft.

Once it is opened up, you can check inside the unit and look for accumulated debris. Plastic, cement, rust and other assorted debris can build up and create an obstruction inside the blower.

Remove any accumulated debris you find. In some cases, you may have to take the unit apart and clean the affected components with solvent.

Rotate the shaft back and forth to determine if there is any motion. If you cannot do a full rotation, you may need to remove the shaft for repairs. Never use a pipe wrench to rotate the shaft under any circumstances. It could bend the shaft and lead to costly repairs. A strap wrench is a much better option.

If the unit is simply rusty, you can apply a PB Penetrating Catalyst to it. Spray a liberal amount over the surface of the headplates, impellers and other internal components. Allow the solution to remain on the components anywhere from a few minutes to a few hours depending on the severity of the rust.

Once the right amount of time has passed, go back and rotate the shaft back and forth again. If you have a Roots unit that features a locknut on the timing gearbox, simply drain the oil out of the gearbox housing and remove the housing cover. Take a socket and a ¾ inch or 1 inch ratchet and use these on the drive motor timing gear nut to rock the unit back and forth in a clockwise direction. Be careful not to loosen the lock nut. Keeping trying to rotate the unit until it turns freely.

Replace the gearbox cover and refill the unit with the amount and type of oil specified in your owner's manual. Then, reassemble the drive and put the piping back into place. Your unit is ready to be energized again. If everything sounds right when it is energized, operate the unit at minimum load for five minutes to ensure proper turning and performance.

If the unit has built up too much internal rust and cannot be made to turn freely with this method, it must be torn down. Each component must be cleaned through sand blasting to remove the rust and then it can be reassembled. If you need to tear down and reassemble the unit, it is a good idea to replace all of your existing bearings, seals and gaskets with newer ones.
