Installation of elastic joint of silencer for pneumatic conveying roots blower:

① Roots blower elastic joint

The elastic joint of Roots blower is also called the soft joint of Roots blower, also called the rubber elastic joint, or the rubber pipe soft joint, or the flange type rubber soft joint, which is composed of fabric reinforced rubber sheet and parallel movable joint, loose metal flange or threaded pipe flange. It is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The elastic joint of Roots blower can eliminate the vibration and thermal deformation of the unit and facilitate the installation of pipes. In brief, Roots blower adopts elastic joint, which is convenient for installation and maintenance of blower, vibration isolation, noise reduction, displacement compensation, leakage and thermal deformation reduction of pipeline.

Some enterprise customers may have doubts about where the elastic connector should be installed and what its important role is after receiving the information equipment. Roots blower manufacturer makes a simple reply to this question, and discusses the installation and characteristics of elastic joints.

② Installation of elastic joint

Indication of installation position of root fan elastic joint

The elastic joint of roots blower can be installed in front of or behind the outlet muffler. A customer asked some time ago: Can the check valve of Roots blower be installed between the muffler and the soft connection? If roots blower has no exhaust device, a one-way valve can be installed between the flexible joint and the outlet muffler; If the blower has an exhaust device, it is better to install a check valve between the tee and the main pipe.

③ Characteristics of elastic joint

The flexible joint is small in size, light in weight, good in elasticity, convenient in installation and maintenance, and can produce lateral, axial and attribute angular displacement during installation. It is not limited by the different centers of the pipes, and the flanges are not parallel, so it can reduce the transmission noise when the structure is working, and has a strong damping capacity. The segmentation can be decomposed into the following features.

1. Compensate installation error

During the design, processing and installation of Roots blower pipes, systematic errors are inevitable. The fan will produce lateral, axial and angular displacement during installation. The use of elastic joints can be free from the restriction of pipe misalignment and flange non parallelism, which can effectively eliminate these errors.

2. Noise reduction and vibration reduction

The elastic joint design mainly studies that the material and structure have sound absorption and vibration reduction performance. When the fan is working, it can reduce the noise of its structure information transmission, and has strong vibration absorption capacity. It can effectively reduce the noise and vibration generated by the enterprise in the fan control system.

3. Good sealing

The elastic joint has excellent sealing performance, and can provide good sealing performance in any medium without gas leakage.

4. High temperature resistance, flame retardant and anti-corrosion

The elastic joint is made of inorganic materials, which has high temperature resistance and flame retardancy. The material structure matching it can be selected according to different working media to solve the corrosion problem.

5. No hard force transmission

The elastic joint is made of flexible material, which can eliminate hard drive, optimize the design of pipeline system, reduce vibration and extend the service life of pipeline equipment.

6. Protect the fan system in case of system failure

When some unexpected faults occur in the system management of the fan, such as abnormal vibration or eddy current impact in the information system of the enterprise, the elastic joint will be damaged earlier, which can protect the fan system.

7. Compensate for thermal expansion

During the operation of fan system, the rapid change of temperature and elastic joint can provide comprehensive compensation in a small space.

8. Convenient installation and transportation

The main body of the elastic joint is made of non-metallic materials, with small size, light weight and good elasticity, which greatly reduces the weight of the product and facilitates installation, maintenance and transportation.

The elastic joint is an indispensable part in the installation and use of Roots blower. The installation is flexible and convenient, which can provide effective protection for roots blower and effective assistance for the good operation of roots blower.
