How to maintain the hydraulic hammer in winter

At the turn of autumn and winter, the temperature difference is large, and more stringent requirements are put forward for the work and maintenance of the crushing hammer. Several suggestions are put forward for the "winter" problem of the crushing hammer, and I hope everyone can successfully winter.

First, a comprehensive physical examination before winter

Before storing the crushing hammer, it is necessary to carry out a safety check on each part of the crushing hammer to find out whether there is a fault or unstable connection and clean the parts of the crushing hammer.

Second, replace the oil seal in advance

The function of the oil seal is to prevent the magazine from contaminating the hydraulic system. Small crushing hammer needs to replace the oil seal in about 500 hours of working time, and large crushing hammer needs to replace the oil seal in about 300-400 hours of working time. When replacing the oil seal, attention should be paid to the cleanliness of the oil seal to prevent impurities on the oil seal from polluting the hydraulic system. Once the oil seal is broken, it is obvious that the crushing hammer has oil leakage, and it will also cause insufficient operating pressure of the crushing hammer due to internal leakage. Therefore, special attention must be paid to the replacement of hydraulic oil seals in winter.

Third, the placement environment requirements

As a precision mechanical equipment, hydraulic crushing hammer has strict requirements for the dryness of the storage environment. It is strictly prohibited to place the hammer in humid, salt-alkali, dusty and other environments for a long time. In order to prevent ground water from entering the hammer, it is recommended to use a support to cushion the hammer. It is necessary to drain the nitrogen in the crushing hammer and push the piston into the middle cylinder block with the drill rod before preventing it.

Fourth, daily maintenance

The working environment of the hammer is very bad, and daily maintenance should be paid attention to in ordinary use. After removing the drill rod, often check the wear condition of the wearing parts in the lower cylinder body, and check the piston, drill rod hitting surface, drill rod, inner and outer sleeves, etc.
