Hollow building formwork production line startup operation steps
DONGFANG STAR
2023 04 23
The hollow building formwork production line should be run empty for 3-5 minutes to check whether there are any abnormalities in the various parts of the machine. If there are any abnormalities, they should be eliminated in time.
According to the equipment manual, connect the power supply, turn the pulley by hand, and check whether the machine is flexible and reliable.
During the operation of the machine, it is forbidden to check whether the motor is normal and the tightness of the belt before starting the machine.
According to the different raw materials, the roller skin gap should be adjusted reasonably. If the roller skin is too tight, it is easy to damage the surface of the pipe, and if the roller skin is too loose, it is easy to cause warping.
The raw materials must be cleaned up, and there should be no debris or dirt on the raw materials. If there are impurities or dirt, it will affect the working effect of the extruder and the quality of the product.
Control the extrusion speed according to the process requirements. If the speed is too fast, the film on the surface of the pipe will be uneven and wrinkled; if it is too slow, there will be more bubbles on the surface of the pipe. Too many bubbles will cause the hollow building formwork to be uneven or cracked after the product is formed.
The raw materials will generate a certain amount of heat during the extrusion process. At this time, the discharge valve should be opened in time to discharge the heat, otherwise the pipe temperature will be too high and deformation, cracking and other phenomena will occur.
According to the different raw materials, reasonably adjust the extrusion pressure and time to ensure product quality.
After the raw materials are extruded, they should be cooled and shaped in time according to the regulations, otherwise the hollow building formwork products will be inaccurate in size and rough on the surface.
Inspection, maintenance and other work, let alone adding oil or water during the operation of the machine.
Lubricate all parts of the machine according to the method specified in the equipment manual.
Generally, the parts should be lubricated, and the moving parts should also be filled with lubricating oil according to the use conditions.
Maintain the machine according to the requirements specified in the hollow building formwork equipment manual.
