Water separators, pressure reducing valves, cylinders and heating plates are the four major components of plastic steel door and window equipment. To ensure the service life of plastic steel door and window equipment, it is a necessary step to test its conventional components. 1. Water separator
Water separators, pressure reducing valves, cylinders and heating plates are the four major components of plastic steel door and window equipment. To ensure the service life of plastic steel door and window equipment, it is a necessary step to test its conventional components.
1. Water separator
The function of the water separator is to remove the liquid oil, moisture and impurities in the compressed air to ensure the normal operation of the pneumatic system. Therefore, it is necessary to check whether the water separator has air leakage and the condensate drain valve is reliable. Whether the filter should be cleaned or replaced, whether the water cup is damaged or cracked.
2, pressure reducing valve
The function of the pressure reducing valve is to adjust the higher air pressure to the pressure that meets the requirements of the use, and keep the adjusted pressure stable. The pressure reducing valve is an important pneumatic component in the plastic window equipment, so it should be guaranteed to be intact. We want Always check the pressure reducing valve for leaks, whether the pressure gauge reading is within the specified range, whether the pressure gauge is continuously adjustable, whether the pressure regulating valve cover can be locked, and if necessary, repair or replace the pressure reducing valve immediately.
3, cylinder
The cylinder is a pneumatic component. In the plastic steel door and window equipment, the mechanical part that is fixed by the cylinder is used to complete the predetermined action. We should always check whether there is air leakage between the piston rod and the end cover of the cylinder; whether the piston rod is scratched, Deformation; whether the pipe joint and the pipe are loose or damaged; whether the buffer valve mother is locked; whether there is abnormal sound when the cylinder is in motion, etc. In addition, the seal ring and the end cap seal ring on the piston should be regularly checked for damage; cylinder and piston Whether the piston rod is damaged; whether the buffer effect of the cylinder is satisfactory.
4, heating plate
The heating plate is the main working part in the welding machine. It is made of cast aluminum. It has heating elements inside. There are two binding posts on it. After the power is turned on, the surface temperature can reach 270°. The function is to heat the end surface of the welded profile to a molten state, and then press and join the two profiles together to achieve the purpose of welding. Since the heating plate is often in motion during the welding process, the terminal is on the binding post. The wire also moves with it. After a long time, the wire will loose or fall off, which will affect the normal operation of the welder. Therefore, we should always check whether the wiring of the terminal is firm.
