Many people have never heard of hydraulic pipe fittings, and they don't even know what it is. Now it is shared with everyone on the principle and removal method of hydraulic pipe joints, and I look forward to helping everyone.
1. Detailed introduction of hydraulic pipe joints
The hydraulic pipe fitting is a connection component, which is a connection joint between the hydraulic oil pipe and the hydraulic oil pipe.
2. The principle of hydraulic pipe fittings
Different types of joints have different principles. Here I will introduce the principles of welded joints. To put it bluntly, welded pipe joints are obtained by electric welding. The joint and butt are sealed with a ring. The structure of this pipe joint is very simple, the manufacturing cost is not high, it is relatively easy to manufacture, and the airtightness is good. It's just that the quality of electric welding is very high, and it is inconvenient to install and disassemble.
3. The removal of hydraulic pipe fittings
The cleaning of hydraulic pipe fittings and joints is divided into kerosene cleaning and pickling passivation. Kerosene cleaning is mainly for air-conditioning copper pipes and stainless steel pipes. First, remove the pipes and joints to be cleaned, and clean the viewing platform on the inside with a cloth dipped in kerosene. Then immediately soak the sides and joints in kerosene and clean them. After cleaning, the specifications cannot be estimated from the pollutants that can be seen. The key to pickling passivation is for seamless steel pipes with severe rust. First, de-oil them, wash them with water, then rust-proof, and then combine them with caustic soda solution. Take care that you don’t need to wash the markings of the pipes. .
