What should I do if the gear vibration occurs when the single-column hydraulic press is working?

by:WORLD     2022-11-11
The single-column hydraulic press will generate gear vibration during operation. What is the reason for this phenomenon? Today, I will take you to know:

① Whether the gear pump of the single-column hydraulic press sucks oil with air bubbles from the oil tank.

② Check whether the rubber parts of the single-column hydraulic press motor and pump coupling are damaged or missing. Damaged or missing installation. This should replace or replace the rubber parts of the coupling.








③ Check the installation concentricity of the pump and motor of the single-column hydraulic press. It should be specified that the installation concentricity of the pump and the motor should be adjusted.

④ Check the connection key or spline. Wear causes radial runout of rotating parts.

⑤ Check the seal on the end face, the pump body is in direct contact with the end covers on both sides. If the flatness of the contact surfaces does not meet the specified requirements, the pump may suck in air during operation. The single-column hydraulic press can grind back and forth with abrasive paste on a flat plate with an 8-shaped path, or it can be ground on a surface grinder so that its flatness does not exceed 5mm, and its perpendicularity requires flat surfaces and holes.








⑥ Check the overfitting contact between the end cover hole of the single-column hydraulic pump and the outer diameter of the gland. If coordination is not good, air can easily intrude from this contact. If the gland is a plastic product, the seal will also loosen and allow air to enter due to its damage or deformation due to temperature changes. Adhesives such as epoxy can be used for sealing.

⑦ Check for damaged or worn parts in the pump. Damaged or worn parts in the pump can cause vibration and noise. If the tooth profile error or pitch error is large, the two gears are in poor contact, the tooth surface roughness is high, the length of the common normal is too poor, and the tooth surface is too small, then the contact area of ​​the teeth of the two gears is not on the index circle. At this point, the gear pair can be replaced. Damage to the needle ball or cage of the bearing, wear of the long and short journals, etc., may cause the bearing to rotate smoothly and produce mechanical noise. In this case, it is necessary to disassemble the gear pump, replace the bearing, and repair or replace the pump shaft of the single-column hydraulic press.
