Excavator is a very common kind of engineering machinery, and the breaker is an indispensable working device in the construction process of excavator. Hydraulic breaker is a crushing tool that uses hydraulic pump as power and hydraulic oil as working medium to convert hydraulic energy into mechanical impact energy, that is, it uses liquid pressure to drive the piston to do work and output energy to work. It is widely used in quarries, mining, national defense construction, highway and railway construction, municipal engineering, construction and other industries. It is very important to match the corresponding breaking hammer for the excavator. If the excavator is installed with an inappropriate breaker, it will not only cause damage to the breaker, but also cause damage to the excavator. This article will introduce the factors affecting the matching of breaker and excavator.
1) Oil quantity factor of excavator
The breaker is a device that works by the hydraulic pressure of the excavator. Only by obtaining the appropriate hydraulic pressure from the excavator can it give full play to its best performance. Generally, the flow of the breaker is 60-80% of the total flow of the excavator.
2) Factors affecting the lifting capacity of excavators
The breaker is the equipment installed on the excavator, so the lifting capacity of the excavator should be able to bear the weight of the breaker. Otherwise, the excavator may dump, unable to complete the work and has potential safety hazards.
3) Working pressure factors of excavator
The maximum working pressure of the excavator is higher than that of the breaker, so the breaker can give full play to its best strength. Generally, the common pressure of excavator shall be 30-40bar higher than the working pressure of breaker.
