Sand machine and the impeller is an the sand maker important part, it is a part of the machine, and also the most vulnerable. Since the completion of the distributed emission materials in the impeller, it is possible material to wear impeller and improper operation. Therefore, in the course of their work to pay special attention to prevent an accident because of negligence in the production process. We know that the head of the shaft to the top of the spindle assembly installed on an impeller of the sand maker. The impeller tapered sleeve joints and keys to provide for a high-speed rotating torque. The broken material from entering the center of the impeller, the upper impeller through the center of the material distributors.
The material is uniformly distributed in the fabric at the center of the cone body sand maker impeller to the all Release wrenches. The wear blocks made from special materials to install the launch of the exit of the runner can be replaced. Impeller material is accelerated to a certain speed projectile. The material lining whirl crushing chamber strongly self-crushed material impact. Cone hat and the impeller in the flow path between the plates of the upper and lower parts of the sand maker the wear amount of the block, so as to prevent it from wear and tear equipped. Stop running on the device, you should pay attention to the first stop feeding, then stopping the discharge device. The feed should be continuous and uniform. Material specifications should strictly abide by the relevant provisions. Otherwise, sand maker can be worn easily, because the material of the impeller.
Under normal circumstances, the transmitted most of the sand pot use of a single motor or a motor-driven belt transmission mechanism. Sand maker dual motor drive installed on both sides of the spindle assembly of the two electric motors. The pulleys of the two motors is connected by the belt and the spindle pulley to ensure that the spindle the stressed balance processing on both sides without the additional torque.
