Analysis of the Reasons for the Noise of the Hydraulic Motor in the Four-column Hydraulic Press

(1) Couplings, gears, etc. of the output shaft of the hydraulic motor are installed out of alignment and different strengths, etc., which can correct the connection parts

of concentricity.

(2) The connections of the oil pipes are loose (especially the oil inlet channel), and the four-column hydraulic press has air entering the hydraulic motor or oil pollution.

(3) The gap between the plunger and the cylinder hole increases due to severe wear, and the gap can be rebalanced by brushing.

(4) The head (spherical surface) of the push rod is severely worn, and the journals at the bearings at both ends of the output shaft are severely worn, and the electric

Plated or brushed journal position repair.

(5) The influence of external vibration, or even resonance, or the hydraulic motor is not installed firmly, etc. find vibration

The reason can be ruled out, such as eliminating the influence of the external vibration source. This article comes from the hydraulic manufacturer WORLD Press Machine official website www.pressmachine-world.com, please indicate the source for reprinting!
