Accumulatorless device

The newly developed and produced accumulator-less hydraulic crusher applies the high-tech theory and cancels the original accumulator device. Simple structure, less failure, easy maintenance, lower cost and increased impact energy. Therefore, users can reduce both use and maintenance costs.

The role of accumulators

The inside of the accumulator is filled with nitrogen gas, which uses the hydraulic breaker to store the remaining energy and the energy of the piston recoil during the previous blow, and releases the energy at the same time during the second blow to increase the striking ability, usually in the When the breaker itself cannot reach the striking energy, the accumulator is installed to increase the striking force of the breaker. Therefore, generally small ones do not have accumulators.

Medium and large are equipped with accumulators.

Classifiion of hydraulic breakers:

There are many types of hydraulic breakers, and there are many classifiion methods.

1. Classifiion according to the operation mode: hydraulic breakers are divided into two egories: hand-held and air-borne.

2. Classifiion according to the working principle: hydraulic breakers are divided into three egories: full hydraulic type, combined liquid and gas type and nitrogen explosion type.

The combined liquid and gas type relies on hydraulic oil and compressed nitrogen at the rear to expand and push the piston to work at the same time. Most of the crushers belong to this type of product;

3. According to the structure of the distribution valve: hydraulic breakers are divided into two types: built-in valve type and external valve type.

In addition, there are various other classifiion methods, such as stroke feedback type and pressure feedback type breakers according to the feedback method;

· Divided into low-noise type and standard type crushers according to the size of the noise;

· According to the shell form, it can be divided into triangular and tower crushers;

· According to the shell structure, it can be divided into plywood type and box frame type crusher and so on.
