The following are effective technical means by Piston Motors to reduce noise and vibration and improve running smoothness:
Through precise machining and optimized assembly processes, the friction and clearance between the piston and the cylinder are reduced, thereby reducing the noise caused by mechanical vibration during operation. In some designs, the resonance effect during operation can be reduced and the vibration amplitude can be reduced through an asymmetrically distributed piston structure.
Using materials with shock-absorbing and sound-absorbing properties, such as high-strength composites or polymer coatings, on pistons, valves and cylinders can significantly reduce noise transmission. High-performance materials can not only reduce friction noise, but also improve the durability of the equipment and reduce vibration caused by gap changes during operation.
Design a smoother hydraulic oil flow path to avoid vibrations caused by local pressure fluctuations or turbulence. Add a buffer chamber or throttling device at the high-pressure fluid inlet to reduce hydraulic impact noise.
Apply advanced sealing technology
The use of efficient seal design can reduce pressure instability caused by hydraulic oil leakage, thereby reducing vibration and noise during operation. High-performance sealing materials (such as fluororubber, polytetrafluoroethylene, etc.) can maintain a stable sealing effect under extreme working conditions and avoid additional vibration caused by sealing failure.
Adding a shock absorbing device or vibration isolation pad to the installation of the piston motor can effectively reduce the noise transmitted from equipment vibration to the external environment. Damping elements, such as rubber buffers or oil film shock absorbers, are added to the internal structure to reduce impact vibration during the reciprocating motion of the piston.
Noise and vibration caused by sudden changes can be reduced through precise speed control and adjustment of operating parameters (such as controlling the rate of pressure changes). Equipped with sensors to monitor key indicators such as vibration frequency and noise intensity, it automatically adjusts the operating status to avoid entering the resonance range.
Add a noise reduction cover or use a soundproof shell to block the spread of noise during operation.
Reduce structure-conducted noise by covering external ducts and connections with sound-absorbing materials.
Fluid Dynamics Optimization
Through CFD (computational fluid dynamics) simulation, the internal flow path of hydraulic oil is optimized to reduce fluid noise and vibration sources. Improve the design of the oil inlet and outlet to avoid fluid pulsation caused by sudden changes in pressure.
By precisely adjusting the operating frequency of the equipment and the natural frequency of the structure, the amplification of noise and vibration caused by resonance is avoided. Adjust the stiffness of the support structure or add damping characteristics to suppress resonance effects during operation.
Improve the processing accuracy of key components (such as pistons, cylinders, valve groups, etc.) and reduce the impact of assembly errors on operational stability. Strictly control the alignment during the assembly process to avoid vibration problems caused by eccentricity.
Through the above technical means, Piston Motors can significantly reduce noise and vibration, while improving the smooth operation and service life of the equipment. The combined application of these measures will make the equipment more environmentally friendly and comfortable while operating efficiently.
