How to reduce the noise of mining winch

Mining winch is a lifting machinery, an indispensable and important production equipment in the coal mine production system, 

and a common equipment for coal mine lifting, coal gangue, lifting or reducing materials. But it has already been used

Noise often happens during journeys, so how to reduce the noise of mining winches? 

The following Starlight Miners will be shared with you.

1. Adopt low-noise motor; Adopt elastic coupling to reduce the vibration and noise caused by the connecting rod;

2. The installation surface of the motor, hydraulic pump and hydraulic valve should be equipped with shockproof rubber pad;

3. Try to replace the pipeline with a hydraulic manifold to reduce vibration;

4. Use accumulators and rubber hoses to reduce vibrations caused by pressure pulsations. 

Accumulators can absorb noise up to 10Hz and are very important for hydraulic hoses. Coal mine winch

Absorb sound. This material can also be used to reduce noise on hydraulic pump housings. Mine hoisting winch

5. Ventilation equipment should be installed in the system.

Surface requirements and treatment of coal mine winch: As the main component of cylinders, columns, 

hydraulic supports, cylinders and other products, the processing quality of the winch directly affects the service life and reliability of the entire product. 

The processing requirements of the cylinder are high, and the inner surface roughness is RA0.4~0.8μm, 

which has strict requirements for coaxiality and wear resistance. The basic feature of the cylinder block is deep hole machining, 

which has always troubled processing personnel.

Due to the residual pressure stress on the surface of the coal mine winch, 

the rolling process is conducive to sealing the microcracks on the surface and hindering the expansion of erosion.

 So as to improve the surface corrosion resistance, delay the appearance or propagation of fatigue cracks, 

and thus improve the fatigue strength of the cylinder. Roll forming, so that the rolling surface forms a cold-hardened layer, 

thereby reducing the elastic deformation of the magic contact surface, 

thereby improving the wear resistance of the cylinder inner wall and avoiding burns caused by wear. 

After rolling, the surface roughness value is reduced in order to improve the mixing properties.

As the control hub of the hydraulic system, the hydraulic system is constantly moving, 

and there are high requirements for the accuracy, sealing and reliability of each component. 

Rolling is mainly used to improve the precision coordination of foreign countries.
