[Operation Tips] Excavator crushing hammer used in this way can not only improve efficiency, but also prolong life!

As one of the most common side parts of construction machinery, hydraulic breaker has been widely used in mining, railroad, highway, municipal and other workplaces. As we all know, hydraulic crushing hammer in the daily work of gnawing are “hard bones” working environment poor conditions, master the correct use of the crushing hammer, not only can improve efficiency, but also greatly extend the service life, reduce the frequency of failure.

1、Gradually move forward, sub-crushing

From the edge to the internal gradually move the impact point, do not try to break a larger block, if 30 seconds can not be broken, it should be broken. When crushing particularly hard objects, you should start from the edge, do not continuously strike at the same point for more than a minute to prevent the brazing rod from burning out or the hydraulic oil from overheating.

2、Strike angle less than 90 degrees

When crushing, the crusher should have an inner angle of less than 90 degrees to the crushed object, and the excavator should constantly adjust the inner angle for crushing when vibrating. There will be some deviation between the direction of the bucket teeth entering in the crushed object and the direction of the crusher itself, please always pay attention to adjusting the curved arm of the excavator to keep the direction of both in use.

3、Choose the proper striking point

Before striking, first impact a point, the depth of 60 to 70cm, and then lift the hammer body, displacement to the original impact point of about 30 to 40cm distance to strike again, so that there will be better results.

4、Installation of water check valve before going underwater

If you need to carry out underwater operations, you must install a water check valve on the top cover of the vibration box.

5、Prevent empty striking

When the object to be broken has been broken, please release the operation pedal of the crushing hammer immediately so that the crushing hammer stops striking. Otherwise (striking without the brazing rod fixed) impacts between the piston and the brazing rod, between the brazing rod and the brazing rod pin, and between the brazing rod pin and the front sheath will cause damage to the brazing rod, the brazing rod pin, and the front sheath.

Why does the hydraulic fluid in excavators turn black? This time it's not because of the heat!

Why does the hydraulic fluid in excavators turn black? This time it's not because of the heat!

Construction machinery on the hydraulic components are many, hydraulic oil in the hydraulic system plays a lubricating role, if not replaced for a long time, the hydraulic oil will become black, viscosity reduction will directly lead to the excavator main pump injection, valves, multi-way reversing valves, oil seals and so on the intensified wear and tear of the various hydraulic system parts, over time resulting in the components of the gap between the occurrence of leakage and seriously affect the excavator's action consistency, powerlessness and other phenomena. Phenomenon.

Excavator hydraulic breaker hammer internal workings in detail

The relationship between the area A1 of the upper chamber of the cylinder and the area A2 of the lower chamber of the cylinder is A1>A2, and A2 is always subject to high pressure. When A1 is changed from high pressure to low pressure, the piston moves upward, accompanied by high-pressure nitrogen in the rear cylinder body under pressure to store energy.

Excavator Hydraulic Breaking Hammer Introduction and Working Principle

Excavator Hydraulic Breaking Hammer Introduction and Working Principle

Hydraulic crushing hammer referred to as “crushing hammer” or “crusher”, the power source of the hydraulic crushing hammer is the excavator, loader or pump station to provide the pressure, it can be more effective in the construction of the project can be crushed stone and rock, improve work efficiency. Selection of hydraulic crushing hammer principle is based on the excavator model, the operating environment to choose the most suitable hydraulic crushing hammer, according to the hydraulic network of senior consultants Li Gong analysis of China's hydraulic crushing hammer is mainly from foreign countries to introduce technology, South Korea's crushing hammer foundation is good, hydraulic network of Li Gong reminds us not to forget to support the domestic technology so that there is a better development.
