In the “excavator technology which is strong? “Big infrastructure” investment wind mouth, the excavator cylinder leading company's stock price rose six times in three years | Independent Research Report ”In the article, we recognize the construction machinery industry chain of excavator special cylinder leading companies.
In today's article, we together again to understand a similarly benefited from the “big infrastructure” wind mouth of the listed companies of the construction machinery generics.
The so-called accessories, the full name is “construction machinery ancillary work devices”, installed in the main machine of construction machinery accessories, can expand the host of applications, such as digging excavators installed on the crushing hammer can drill the ground.

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

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.
