How does the injection machine exhaust?
On the system pressure plate there is a relief valve, the valve head at the top of the six angle bolts loose on it
Vibration phenomenon h and exhaust does not matter much, the machine does not adjust the shock feet at the level on it
It's OK to apply some oil to the oil port and then turn on the engine so that he can turn a little more
Holding action. If the pressure is shaking, consider air. Methods: the exhaust can release the pressure proportional valve on the inner six angle screw, slowly to the pine, loosen the shake, if there is air in the pipeline, there will be a spray, and then slowly to flow to the oil outflow, no air bubbles can be, and then tighten the screws.
1, the mold cylinder formed a negative pressure, inhalation of air from the outside. Concrete method: first, apply the butter on the joint surface of the connecting parts, make several opening and closing dies, observe whether there is any change or not. If so, tighten the screws and joints tightly.2, check whether the suction pump air. Specific methods: check whether the oil absorption port layout specifications; oil in the air will be removed.3 、 the pipeline is too long or the suction height is too high, it is difficult to exhaust. Specific method: with exhaust valve, repeatedly doing the opening and closing mold action exhaust; if not, then have to design and install a slightly (usually in the highest position).4, is it a new cylinder, or repair mold cylinder, or did not start for many days?. In this case, do more warm-up exercises, the air naturally discharged.
