As the saying goes, if you don't do it in 1929, walk on the ice in 3949 and look at the willows along the river in 5969. Now is the coldest time of the year. For friends who use the broken hammer, maybe some have left the love hammer idle, or some are still struggling in the cold days.


Now let's share how to make the crushing hammer survive the winter safely:


1. Comprehensive physical examination


Before storage, the idle hammer shall be subject to safety physical examination to check whether there are faults and loose screws, and the whole hammer shall be cleaned.


2. Replace the oil seal


The oil seal can prevent impurities from polluting the hydraulic system. Once the oil seal is broken, it is obvious that there is oil leakage from the breaking hammer, and the working pressure of the breaking hammer is insufficient due to internal leakage. Therefore, the oil seal of small crushing hammer needs to be replaced when it works for about 500 hours, while the oil seal of large crushing hammer needs to be replaced when it works for 300-400 hours, and pay attention to cleaning when replacing the oil seal. Especially in winter, due to the cold weather, the sealing performance of the oil seal is not good. Pay more attention to the frequent replacement of the oil seal.


3. Precautions for placement


The crushing hammer shall be placed in a dry indoor environment, not in a humid, saline alkali, dusty environment for a long time. In order to prevent rainwater from entering, the rear cylinder block shall be padded up, and it is best to store it in a room with low humidity. If it is not used for a long time, it is necessary to drain the nitrogen and push the piston into the middle cylinder with a drill rod.


4. Maintenance cannot be stopped


The working environment of the crushing hammer is very bad. Pay attention to daily maintenance in normal use. After removing the drill rod, frequently check the wear condition of vulnerable parts in the lower cylinder, and check the piston, drill rod striking surface, drill rod, inner and outer sleeves, etc.


The above is that after the crushing hammer is idle, special attention should be paid to its placement. The crushing hammer is easy to damage the machine because it is placed for a long time.
