What Causes The Pressure Pump To Shake Violently?

The violent shaking of the hydraulic pump is usually a clear signal that the hydraulic system is abnormal, this unusual phenomenon will not only significantly affect the overall performance of the hydraulic system, but also may cause serious damage to the hydraulic components, which leads to the stagnation of the entire production equipment and high maintenance costs. Therefore, it is particularly important to understand and quickly deal with the causes of severe shaking of hydraulic pumps. The following are the main causes of hydraulic pump jitter:

First, air mixing.

When the air is inadvertently mixed with the hydraulic oil, it will have a series of negative effects, such as the incompressibility of the oil is significantly reduced, which often leads to the occurrence of cavitation effect, and then cause irregular vibration during the operation of the hydraulic pump. Cavitation will not only affect the working efficiency of the pump, but may even cause damage to the internal parts of the hydraulic pump, resulting in unstable operation.

2. The speed is too high.

When the operating speed of the hydraulic pump exceeds its design range, the oil absorption process may not keep up with the oil discharge speed of the pump. This mismatch will lead to insufficient oil absorption, resulting in pressure fluctuations in the pump, and eventually lead to violent pump shaking. In industrial applications, it is important to set the pump speed reasonably, too fast speed will not only accelerate the wear of parts, but also may affect the overall performance of the hydraulic system.

3. System overload.

At this time, the working state of the pump often becomes unstable, resulting in a decrease in the efficiency of the equipment and greatly affecting the safety of the operation. Under heavy load or strong demand, the durability and reliability of hydraulic pumps are severely tested, so the work load should be monitored frequently to ensure that it is operating within a safe range.

Four, hydraulic oil viscosity.

Whether the viscosity is too high or too low, it will cause the hydraulic pump to run poorly. When the viscosity of the hydraulic oil is too high, the resistance that the pump needs to overcome in the process of oil absorption will increase, resulting in the pump oil absorption becomes extremely difficult; If the viscosity is too low, the lubrication performance of the hydraulic oil will be affected, further aggravating the friction inside the pump and inducing violent shaking. Therefore, choosing the right hydraulic oil and regularly monitoring the state of the oil are essential to ensure the normal operation of the equipment.

5. Improper installation of hydraulic pump.

If the axis of the pump shaft and the drive motor are not aligned during the installation process, or the precision of the alignment is not enough, additional mechanical stress will be generated during the operation of the pump, resulting in the pump body shaking. This will not only affect the efficiency of the pump, but also cause unnecessary wear and fatigue to the internal parts, so in the installation process of the hydraulic pump, it is necessary to maintain a precise alignment state to ensure that the equipment can run smoothly and efficiently.
