Learn about the precautions for the use of prestressed plastic corrugated pipe equipmentPrestressed plastic corrugated pipe equipment is a complete set of equipment and production line for manufacturing prestressed plastic corrugated pipes. Plastic corrugated pipe is a new type of pore-forming material, which is widely used in the construction industry. When operating the prestressed plastic corrugated pipe equipment, we need to pay attention to some precautions.
Put the uniformly stirred plastic particles into the hopper of the extruder, and turn on the speed control button of the host. Under normal circumstances, the starting speed is between 10Hz and 15Hz, and the current is between 25 and 35. When the current is too high, the temperature should be adjusted. After adding the particles, the machine usually extrudes the plasticized tube blank from the mold within about 10 minutes, and observes whether the discharge around the mold is uniform. If the wall thickness of the tube is different, the wall thickness of the tube will be adjusted accordingly. In this case, the discharge around the mold will be tightened by M20 screws, and the opposite screw will be loosened until the discharge around the mold is uniform. Manually pull the tube blank to the shaping sleeve of the forming machine, start the forming machine at a speed of 10Hz-20Hz, and turn on the water inlet pump at the same time, and start when the water tank of the forming machine is full of water

Move the water pump, then start the vacuum pump, open the bleed valve, hold the tube blank with your right hand, do not use the sizing sleeve to rotate the pipe, use the water pipe on the forming machine to get the pipe out of the sizing sleeve, and slowly close the deflation with your left hand The valve will gradually increase the vacuum degree until the vacuum degree is adjusted to the required vacuum degree. Usually the mixed PE material can be between -0.02Mpa. The lower the vacuum pump, the better while ensuring the appearance of the pipe and corrugated molding. Pull the forming tube onto the tractor. The pulling speed should not be too fast or too slow. Too fast will stretch the pipe ripples and make the pipe bend too slowly. The function of the tractor is to evenly send the pipes to the sawing machine according to the speed of the forming machine.

Learn about the precautions for the use of pre-stressed plastic corrugated pipe equipment: When stopping, it is forbidden to supply materials to the pre-stressed plastic corrugated pipe equipment. According to the nature of the broken plastic, regularly check the sharpness of the fixed blade and the rotating blade. Generally speaking, new waste and lower corner materials will be inspected every six shifts, and waste recycling materials will be inspected every two shifts. If the blade is not sharp, it should be sharpened in time. If the blade is in good condition, you can continue to use it. At the same time, check whether the bolts that fasten the blades are loose. If it is loose, tighten it immediately. The feed of prestressed plastic corrugated pipe equipment should not be overloaded. The crushing process should proceed evenly. If there is an overload during the process, the feeding should be stopped immediately, and the feeding should be carried out after the machine returns to normal. . During the operation of the prestressed plastic corrugated pipe equipment, if there is any abnormality, it should be shut down immediately.
