Powder conveying blower manufacturer: what is Roots blower

The principle of Roots blower is: the impeller is directly driven by the motor to rotate. During operation, air convection and pressure difference are used to inhale and compress the gas in the machine (vacuum pump) and then discharge it; when the volume of the discharged gas is greater than the inlet gas, it enters the suction chamber along the axial direction to compress again and increase its temperature And pressure. This repeated cycle to achieve continuous pumping or exhaust process, so as to achieve the purpose of conveying the medium. Due to the special simple and compact mechanical structure, convenient installation, reliable operation, long service life, no wearing parts, easy maintenance, etc., it is widely used in industrial fields such as chemical fertilizers, food, pharmaceuticals, building materials, electricity and so on. According to different uses can choose explosion-proof type ordinary type and flameproof type three types.

Powder conveying blower manufacturers: how to choose the right Roots blower

1. Model selection

(1) Determine the required air volume and the required pressure ratio range

(2) consider the size of the motor power

(3) Calculate the required speed

(4) Determine model specifications

(5) Pay attention to the selection of supporting equipment

2. Material requirements for stator and rotor

(1) Made of alloy steel

(2) have sufficient strength

3. Requirements for bearing type

(1) Use high-precision special grease

(2) Fill bearing housing bore with grease

4. Requirements of transmission mode

(1) Gear type

(2) Belt drive

5. Requirements for protection level

6. Other requirements

(1) better sealing performance

(2) good corrosion resistance

Powder conveying blower manufacturers: What are the matters needing attention in purchasing

1, before buying should first understand the technical indicators of the product

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

2, according to the parameter values provided by the product sample to select.

For example, if a cooling tower is required, indicate the size of the air inlet D2mm × D3 mm or the size of the air outlet D4mm × D5mm, etc. The corresponding piping connection diagram shall also be provided.

3. Check the appearance quality

Including whether the parts are damaged, deformed and paint peeling, etc., if there is any abnormal situation, the manufacturer shall be notified in time to replace the parts or return the goods. (Note: There are differences in product quality due to different levels of production processes from different manufacturers.)

4. Try turning

Turn on the power switch and start the machine to rotate for 2-3 minutes to observe whether there is noise or other abnormal phenomena. If there is, stop the machine immediately for inspection and troubleshooting before restarting the machine.

Powder conveying blower manufacturer: what matters should be paid attention to when using roots blower?

(1) Regular maintenance and maintenance are required. In order to ensure safety and long-term service life, it is necessary to regularly clean the filter screen and other parts to remove dust and dirt and prevent clogging of the filter.

2) Do not overload work.

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

4) Avoid approaching heat sources.

5) It is forbidden to start empty vehicles

6) No lifting with load

7) High-speed reverse rotation is not allowed

8) Do not start or stop the blower frequently

9) When oil leakage is found, repair it in time.

10) Cut off the power supply line when not in use for a long time
