Analysis of the causes and preventive measures of hydraulic breaker piston strain

　　Hydraulic breaker is an important equipment in mining, construction and other projects. The abnormal wear of its core component piston (commonly known as "strain") will directly affect the performance and service life of the equipment. This article will analyze the common causes of piston strain in detail and provide practical prevention suggestions.

　　I. The main causes of piston strain

　　1. Insufficient lubrication

　　Hydraulic oil contamination or insufficient oil will cause the lubrication between the piston and the cylinder to fail, and the direct friction of the metal will generate high temperature, which will cause surface scratches and even adhesion wear.

　　2. Hydraulic oil contamination

　　Impurities (such as metal particles and dust) enter the hydraulic system and become "abrasives" when circulating with the oil, accelerating the wear of the piston surface.

　　3. Material or process defects

　　Insufficient piston hardness or improper heat treatment

　　The smoothness of the inner wall of the cylinder body does not meet the standard

　　Irrational design of the bushing clearance

　　4. Improper operation

　　Long-term overload work

　　Frequent empty hitting (excited when not in contact with the crushed object)

　　Failure to regularly replace the filter element/hydraulic oil

　　5. External environmental factors

　　Dusty, high humidity or extreme temperature environments will aggravate component aging.

　　2. Prevention and solutions

　　Regular maintenance

　　Replace hydraulic oil and filter element every 500 hours

　　Check whether the lubrication pipeline is unobstructed

　　Standardized operation

　　Avoid empty hitting and tilting operation

　　Match the equipment model suitable for the operation intensity

　　Select high-quality accessories

　　Use chrome-plated or nitrided reinforced pistons

　　Use hydraulic oil of the original model specified by the manufacturer

　　Add protective measures

　　Add dust cover when working in dusty environment

　　Preheat the hydraulic system before starting in cold areas

　　3. Summary

　　Piston strain is a typical fault of hydraulic breaker, but it can be effectively avoided through scientific maintenance and standardized operation. It is recommended that users establish regular maintenance records and deal with early signs of wear (such as oil discoloration and reduced efficiency) in time to extend the life of the equipment.
