      Tianjin Blower Group Co., Ltd. is a professional manufacturer of various fan designs and manufacturers. The company has engineering and technical personnel, advanced processing equipment, production technology and perfect detection methods and management systems, strong technical force and stable product quality.

      Principle and characteristics of variable frequency control

      With the continuous development of science and technology, AC motor speed regulation technology is widely used. Through the new generation of full-control electronic components, the frequency change of the AC motor is controlled by the inverter to control the flow of the fan, which can greatly reduce the energy loss caused by the previous mechanical control of the flow. Energy saving principle of frequency conversion regulation:

      It can be known that when the speed is reduced to half of the original rated speed, the flow rate, pressure, and shaft power corresponding to the operating point are reduced to the original 1/2, 1/4, and 1/8, which is how the frequency conversion adjustment method can greatly Reasons for saving electricity. According to the characteristic of frequency conversion adjustment, for the sewage treatment process, the aeration tank always maintains a normal liquid level of 5m, and the blower is required to perform a wide range of flow adjustment under the condition of constant outlet pressure. When the adjustment depth is large, it will The wind pressure drop is too large to meet the process requirements. When the adjustment depth is small, it will not show its energy saving advantages, but will make the device complicated and high one-time investment. Therefore, under the condition that the aeration tank of this project needs to maintain a liquid level of 5m, it is obviously inappropriate to use the frequency conversion adjustment method.

      Reasons for excessive Roots blower pressure:

      1. The pressure of sewage aeration roots blower depends on the resistance it receives, as long as it can withstand the pressure range, it can work normally. For example, if you aerate in a pond with a depth of 2 meters, the pressure of the blown air is 20 kPa. At a depth of 3 meters, the pond becomes 30 kPa. As long as the motor output power can reach the load.

      2. If the pressure displayed by the pressure gauge is greater than the pressure that should be output, it may be caused by blocked pipes, blocked aeration heads, etc.

      Roots fan causes large motor current:

      1. Compared with the specified pressure, the pressure difference is large, that is, the back pressure or the inlet pressure is high.

      2. Compared with the flow required by the equipment, the fan flow is too large, which increases the pressure.

      3. The inlet filter is blocked and the outlet pipe is blocked or blocked.

      4. The rotating parts collide and rub (stuck).

      Solutions to excessive Roots blower pressure:

      1. Reduce the pressure to the specified value.

      2. Put excess gas into the atmosphere or reduce the speed of the blower.

      3. Remove obstacles.

      4. Stop the machine immediately and check the reason.

      5. Adjust the oil level to the correct position.

      6. Check the belt tension and replace it with a large diameter pulley.

The company has engineering and technical personnel, advanced processing equipment, production technology and perfect detection methods and management systems, strong technical force and stable product quality.

      At present, with the rapid development of the economy, various industries have also accelerated the pace of development, such as the development of cement, aquaculture, electricity, flour processing, coal industry, textiles, chemical industry and other industries. Broad market demand space. Slowly use high-pressure roots fans.

      Then the Roots blower manufacturers should remind everyone that the high-voltage Roots blower operation staff must master the common troubleshooting methods. For this reason, the chapter Chuluots blower manufacturers will introduce the failure analysis and troubleshooting methods of the high-pressure Roots blowers one after another.

      Impellers are an important part of high-pressure roots fans. Most of the roots fans currently on the market are three impellers, that is, three-leaf roots fans. These impellers usually fail:

      1. There are contamination impurities on the impeller, which causes the gap to be too small. At this time, you only need to remove the dirt, and check the internal parts for damage. If there is damage, repair or replace it in time.

      2. Gear wear, Tianjin fan , large backlash is a common problem of high-pressure roots blowers, especially for long-time blowers, the gear wear is more serious. At this time, the gear clearance needs to be adjusted. Gears should be replaced between 30% and 50%.

      3. The gears of the high-pressure roots blower are not firmly fixed, and the impeller cannot be synchronized. It is necessary to reassemble the gears and maintain a taper with a contact area of 75%.

      4. Bearing wear of high-pressure roots blower can cause clearance to increase. At this time, the bearing needs to be replaced.
