● Embedded plates, turning tools, milling cutters, planers, drill bits, etc; (4) Special fasteners. Before use, the hole position must be reinforced or tapped, with a tapping hole size of 1:m or 1:1.
Before installation, it is necessary to check whether the product model, tag number, and specifications match, and whether the entire machine parts are damaged or loose.
Before installation, the pipeline should be cleaned, and there should be sufficient straight pipe sections at the valve inlet and equipped with filters. The flange connection between the valve body and the pipeline should pay attention to coaxiality.
The installation site should consider the safety of personnel and equipment, which is not only convenient for operation, but also conducive to disassembly and maintenance.
The valve should be installed upright and vertically on a horizontal pipeline. When necessary, it can be installed tilted to avoid horizontal installation as much as possible. In situations where the valve has a large self weight or vibration, a support frame should be used.
The direction of medium flow should be consistent with the arrow on the valve body. The air source should be dry and oil-free. Valves should be used in environments with an ambient temperature of -20~55 ° C.
● Cleaning valves: For cleaning general media, simply rinse with water. But for cleaning harmful media, it is necessary to first understand their properties and then choose corresponding cleaning methods.
● Valve disassembly: Remove rust from the exposed surface of the parts, but before removing rust, protect the valve seat, valve core, valve stem, and fluid connections. When the valve disc and valve body surface are worn, use a screwdriver to stagger it from the valve disc and then make a valve.
Use parts that require power supply. There are differences between plasma arc cutting and electric welding, which cannot be measured under 6000 arc.
During general cutting, the cutting speed should be slow to avoid cutting too quickly. If the cutting speed is too fast, it will damage the cutting part. According to the situation, the welding parameters should be adjusted properly.
Plasma cutting is subjected to force vibration. When the nozzle collides with the computer reference plane, plasma cutting auxiliary gas flows out of the nozzle and then cuts irregular thin plates.
Plasma cutting is generally used in situations with strong curved surfaces, such as instruments, electrical appliances, machinery, automotive manufacturing, light industry, textile light industry, and electronic information. In order to ensure the best cutting quality, it is generally necessary to check the type of gas, gas pressure, temperature, etc.
