Characteristics Of Hydraulic Lift System Vibration And Self Propelled Scissor Lift
The platform height of the CLMS scissor-type aerial work lift is 12m, the operating height is 14m, the vehicle width is 1.15m, the rated load of the working platform is 300kg, and the extended platform with a rated load of 115kg has an extended length of 0.9m. It can realize the selection and switching of various walking modes, and the climbing ability of 25%, which can be conveniently loaded and unloaded when the vehicle is transported in transit.
Convenient transportation and smooth operation
The telescopic extension sub-platform has a larger working space, and with the folding platform, it is more convenient to transport and move. The industry's most advanced automatic pothole protection system widened wheelbase design, and uneven ground can also let you move freely.
Environmentally friendly construction and convenient maintenance
Pure electric drive, zero-emission, low noise, and more environmentally friendly construction. The integral swing-out tray is convenient for inspection and maintenance.
Universal and modular design
The modular design of the whole machine ensures the generalization of parts and components, making maintenance more convenient for customers and making the cost more competitive.
While hydraulic lift equipment brings a lot of convenience to people, the shortcomings of hydraulic lift systems, such as leakage, vibration, noise, and difficult maintenance, are also troublesome.
The vibration of the lift can easily damage the hydraulic components, impair the working performance of the machine, and affect the service life of the equipment, while the noise may affect the health and mood of the operator and increase fatigue of the operator.
Sources of vibration and noise in the hydraulic system: There are many sources of vibration and noise in the hydraulic system, including mechanical systems, hydraulic pumps, hydraulic valves, and pipelines.
1. Vibration and noise of lifting machinery system
The vibration and noise of the mechanical system are mainly caused by the mechanical transmission system driving the hydraulic pump, mainly in the following aspects.
1) Unbalance of the rotating body
In practical applications, most motors drive hydraulic pumps through couplings. It is very difficult to achieve a complete dynamic balance of these rotating bodies. Noise due to bending vibration.
2) Improper installation
The hydraulic lift system often causes vibration and noise due to installation problems. Such as poor support of the system pipes and defects in the foundation, the elevator or the hydraulic pump not concentric with the motor shaft, and the coupling being loose, which will cause large vibration and noise.
2. Vibration and noise generated by the hydraulic pump
The hydraulic pump (hydraulic motor) is usually the most important hydraulic component that generates vibration and noise in the entire hydraulic system. Hydraulic pumps generate vibration and noise, on the one hand, due to mechanical vibration, and on the other hand, due to changes in the accumulation of liquid pressure and flow.
1) Periodic change of hydraulic pump pressure and flow
The gears, vanes, and plungers of the hydraulic pump cause periodic flow and pressure changes in the corresponding working chamber during the process of oil suction and oil pressure, which in turn causes the pump The flow and pressure pulsation of the hydraulic pump causes the components of the hydraulic pump to vibrate, and the vibration of the components causes the air in contact with it to vibrate with changes in density, and then the sound pressure waves that generate noise propagate out.
2) Cavitation phenomenon of hydraulic pump
When the hydraulic pump is working, if the resistance of the hydraulic oil suction pipe is too large, the hydraulic oil will not be able to fill the oil suction chamber of the pump at this time, causing a partial vacuum in the oil suction chamber and forming a negative pressure.
If the pressure just reaches the air separation pressure of the oil when lifting the platform, the air originally dissolved in the oil will be precipitated in large quantities, forming free air bubbles.
We hope this product knowledge can help users understand this product better, and help in daily maintenance and repair.
