What to Do with a Strained Hydraulic Breaker Piston

In the process of using，hydraulic Breaker will not work properly and oil leakage and other failures, these failures are mostly caused by the Hydraulic Breaker piston strain caused by what led to the Hydraulic Breaker piston damage, and how should we deal with it? This article will provide you with a detailed introduction.

1. Hydraulic breaker piston strained reason

In order to make the hydraulic hammer can work normally, the piston must be in the cylinder body without obstruction to do reciprocating motion. In the actual working process of the hydraulic breaker, there is often a phenomenon that the piston is strained (especially the larger specification hydraulic breaker) and the oil leakage can not work. Piston in the cylinder to achieve unimpeded reciprocating motion, must meet: piston and cylinder with appropriate fit clearance; piston and cylinder between the hydraulic oil film as a hydraulic support. Therefore, may lead to piston strain causes are described below.

(1) Hydraulic oil temperature. When the oil temperature rises, the power of the hydraulic oil viscosity decreases, when the temperature rises to a certain level, the power of the hydraulic oil viscosity drops sharply, by the self-weight and the piston reciprocating movement of inertia, the hydraulic oil oil film may not be established, so that the piston and the cylinder between the hydraulic support (oil film) damage, resulting in piston strains.

(2) Hydraulic oil deterioration. If the hydraulic oil oxidation deterioration, mixed with water, air, then its viscosity will decline, thus destroying the piston and the cylinder between the hydraulic support (oil film); If the hydraulic oil is mixed with particles of dirt, then the piston and the cylinder gap will be affected, not only will increase the cylinder and the friction of the piston, but also affects the piston and the cylinder between the hydraulic support.

(3) piston and cylinder clearance. Piston and cylinder clearance by the material, heat treatment and temperature and other factors. Generally speaking, the material will be deformed with the change of temperature, but through appropriate heat treatment can reduce the amount of deformation.

(4) Hydraulic breaker hammer working process of the brazing rod deflection in the actual working process of the hydraulic breaker hammer, there will often be brazing rod deflection phenomenon, coupled with the brazing tail and piston striking surface is not absolutely flat, so it will produce lateral force, which will lead to piston straining.

2. Preventive measures for hydraulic breaking whacker strains

In order to extend the service life of the hydraulic breaker and reduce the possibility of piston strain, you can start from the following aspects.

(1) Regularly test the excavator hydraulic oil cooling system is working properly, to ensure that the excavator working process of hydraulic oil temperature rise in the normal range.

(2) Regular testing of hydraulic oil, if not in line with the oil cleanliness standards, must be replaced in a timely manner.

(3) According to the cylinder or piston materials used and heat treatment, select the appropriate fit clearance.

(4) In the actual work process, should try to avoid the hydraulic breaker hammer brazing rod deflection. In order to avoid the phenomenon of brazing rod beating, first of all, to ensure that the brazing rod and piston contact surface uniformity; secondly, reduce the hardness of the brazing rod, to prevent the use of brazing rod by the piston in the process of breaking, cracking; finally, in the process of use to check the cylinder buffer sleeve, buffer seat integrity, to prevent damage to the buffer device caused by the piston in the stroke of the eccentricity.
