Pay attention to antifreeze when the injection molding machine stops in winter
1. When the machine is shut down in winter, when the indoor temperature is lower than zero, the cooling elements on the injection molding machine need to be antifreezed.
2. First, close the cooling water tower, water pump, freezing water machine, mold cooling system, etc., and close the water source for injection molding machine and auxiliary machine.servo type injection molding machine.
3. The main cooling elements on the injection molding machine include: oil cooler, water drain, water distributor, water quality filter, and the cooling system of the melt rubber tube.precision core parts.
4. After closing the water source for the injection molding machine, remove the main cooling water pipe, drain the water in the cooling pipe, and then blow out all the residual water in the cooling element with compressed air.
5. When the injection molding machine is used again, reinstall the water pipes and inlet and outlet joints of the cooling elements, and check and clean the inlet and outlet water filter screen of the oil cooler.household plastic mold.
Water flow separator
1. Close the inlet/outlet valves, remove the outlet pipes of the water flow separator, and fill the water with containers.
2. Loosen all the adjusting handles of the upper and lower rows of the water separator clockwise to the bottom to drain the water in the water separator.
Freezer
1. Close the inlet/outlet and make-up water valves of the freezing water machine.
2. Open the ball valve at the water outlet of the chiller and drain the water in the chiller.
Water drainage part of injection molding machine
1. Close the inlet/outlet valve, remove the water inlet/outlet pipe, and fill the water with a container.
2. Open the inlet/outlet water ball valves of the water drainage and drain the water.
Oil cooler
1. Close the inlet/outlet valve, remove the cooling inlet/outlet pipe, fill the water with a container, and drain the water from the oil cooler.
2. Use a wrench to remove the drain plug of the oil cooler, and then use high-pressure air to blow air from the inlet pipe to blow water out of the drain.
3. The inlet/outlet pipes are sealed with sealing caps, and the drain plugs are tightened.
Cooling water tower
1. Close the inlet/outlet and make-up valves of the water tower.
2. Open the ball valve at the water outlet of the water tower and drain the water in the water tower.
Cooling water tower water pump
1. Turn off the power supply of the water pump motor, and close the inlet/outlet and make-up valves of the tower.
2. Remove the flange screws at both ends of the water pump pipe and drain the water in the pipe.
