1. Correct actual operation can improve the working efficiency of the hydraulic hammer and prolong the service life of the hydraulic hammer of the small excavator. Jiushan Machinery reminds mini excavator drivers to pay attention to the following aspects when working.

(1) The drill pipe of the hydraulic hammer is perpendicular to the surface of the object to be pressed from beginning to end, and the object to be pressed is pressed with the drill pipe. After breaking, stop the hydraulic hammer directly to avoid empty hitting.

(2) When breaking very hard objects, tap gradually from the edge first, do not tap continuously for one minute at the same point, so as not to damage the drill pipe or overheat the gear oil.

(3) When the small excavator rotates, the drill pipe does not have to touch other objects.

(4) When working in water, only the drill pipe can be infiltrated into the water. If you really need to do all the underwater work in a hydraulic hammer, you should buy a special underwater engineering hydraulic hammer from the manufacturer.

2. Maintenance

Due to the extremely extreme working standards in hydraulic hammers, proper maintenance can reduce common equipment failures and extend equipment life. In addition to the common maintenance of small excavators, the following aspects should also be paid attention to.

(1) Visual inspection

Check the clearance between the drill pipe and the bushing, and check whether there is any extravasation of gear oil during this period. If there is oil leakage, it means that the low-pressure oil leakage seal is damaged and should be replaced by professional technicians. Check for loose anchor bolts and damage to the shaft pin at the repair joint.

(2) Wetting

Add grease to the lubrication points of work equipment at least twice a day.

(3) Replace the filter element and gear oil.

Introduction to Excavator Hydraulic Breaker

Hydraulic breakers are referred to as "breakers" or "breakers". The power source of hydraulic breakers is the pressure provided by excavators, loaders or pump stations. work efficiency. The principle of choosing a hydraulic breaker is to choose the most suitable hydraulic breaker according to the model of the excavator and the operating environment. According to the analysis of Li Gong, a senior consultant of Hydraulic Talent Network, my country's hydraulic breaker is mainly imported from abroad. Well, Li Gong from Hydraulic Talent Network reminds everyone not to forget to support domestic technology so as to have better development.
