Nachi Hydraulic Pump Repair

Nachi hydraulic pump after a period of use, the parts will gradually wear out and even damage, which will make the hydraulic pump motion accuracy and working performance reduced, and even produce oil pressure can not be hit, oil supply is reduced, noise aggravation, vibration increase and a series of abnormal phenomena, these phenomena are often hydraulic pump parts wear or damage symptoms.

The cause of hydraulic pump damage：

1. Friction and wear

If you look carefully with a magnifying glass, you will find that the surface of the parts after manufacturing is always uneven, after the operation and wear of the hydraulic pump, the metal particles will fall from the surface of the parts, and the uneven places will be flattened, and if the friction continues after this, it will produce deep marks or grind the size small.

2. Abrasive grain wear

There are many solid particulate contaminants on the surface of the parts of the hydraulic pump, and more than 20% of these polluting particles are silica and metal oxides. These wear is the most serious component of hydraulic pump parts, they are sandwiched between the surface of the part, in the movement equivalent to the role of abrasive, resulting in severe abrasive grainy wear.

3. Pit wear

This is a kind of fatigue damage of nachi hydraulic pump parts, under the action of alternating loads, due to periodic compression and deformation, residual stress and metal fatigue phenomenon will produce tiny cracks on the part, resulting in small pieces of stone on the surface of the part peeling.

4. Corrosive wear

The surface of the hydraulic pump component is subjected to the erosion of corrosive substances such as acids and moisture in the oil, and the metal surface will be gradually damaged.

5. Accident damage

In the process of using the hydraulic pump, if the violation of the hydraulic pump operation control procedures and maintenance regulations, will cause serious overload and overspeed, or the hydraulic pump parts have been loosened will fall off when still forced to start, as well as after dismantling and repairing, tools and other foreign matter fell into the pump, the above phenomena will cause damage to the hydraulic pump.

The repair of hydraulic pumps：

For how to repair the damage of nachi hydraulic pump, Elephant Fluid Power company has a wealth of experience and good solutions, will be according to the cause of the damage to the right medicine, so that you have a great experience in the use of the process and during the repair process. Elephant Fluid Power will mainly take the following measures to repair the nachi hydraulic pump: add hydraulic oil, remove foreign objects in the tube, replace the sealing ring, replace the worn gear oil pump or oil pump bushing, load the unloading sheet and sealing ring into the oil chamber to keep the two bushings balanced, clean the hydraulic pump system, replace the hydraulic oil, adjust the concentricity of the hydraulic pump and the motor coupling, reduce its error, replace the qualified pump shaft oil seal, etc.

In the process of using the hydraulic pump, as long as the maintenance is carried out correctly and the occurrence of various types of faults is eliminated, the wear of the hydraulic pump parts will be greatly delayed, and the wear parts will be repaired in time, which will also greatly increase the service life of the hydraulic pump. Choose Elephant Fluid Power, you can rest assured and give you peace of mind!
