By reducing the labor intensity of workers, improving productivity, pro- moting the realization of mechanized molding and core production pro- cess. 2.What points should be paid to in clay sand equipment in wet sand casting?
Control of old sand temperature: the high temperature of type sand may lead to the casting of sand filling, rough appearance, sand punch- ing, pores and other defects. Hot sand problem: the negative impact of hot sand on the quality of casting products, including the type sand function which is difficult to control, the change of type sand function, the appearance of hot sand gathering moisture, and the decrease of core strength caused by the evaporation and condensation of hot sand on the cold core.

3.How to control the quality of clay wet sand?
Choose the right formula: according to the casting requirements and process requirements, select the appropriate clay type and proportion, to ensure the smoothness and accuracy of the casting surface. Mois- ture content control: strictly control the moisture content to ensure the strength of the sand type and casting quality. Viscosity and fluidity control: adjust the viscosity and fluidity by controlling the clay particle size distribution, adhesive type and proportion, and to ensure the qual- ity of sand shape molding and casting shape accuracy. Sand drying performance: strictly control the drying temperature and time of sand type to remove excess water and prevent the casting. Sand type quality control: strictly control the quality of sand type to ensure the molding quality of the casting.
4.What are the maintenance and operation procedures for the clay sand production line?
Check the vibration motor: check whether the vibration force of the two vibration motors is consistent, and whether the eccentric block is
loose. Cleaning and inspection: clean the sand stained in the tank, check the tightness of the triangle belt, the wear of the
wear-resistant plate, and the sand stained inside the sand roller. Motor reducer check: check the motor reducer operation has no sound, oil level, whether there is oil leakage and oil seepage phenomenon. Belt and chain inspection: check whether the belt has any deviation, chain tightness, timely adjustment and lubrication.
5.What should I pay attention to before starting the clay sand treatment equipment?
Check the bolts and insulation: check whethe the fixing bolts of each swing motor are loose and whether the lead insulation is damaged. Check the spring and lubrication: check the spring cracks and the motor needs grease. Check the magnetic concentrator and bucket machine: check whether the bolts are loose, the belt is loose or deviation, check whether the entrance of the bucket machine is smooth and whether the interior is blocked.
6.How to quickly locate and solve the failure of clay and sand equip- ment?
Bearing problem: check whether the bearing runs flexibly, replace the damaged sealing ring to ensure that the bearing is not hot. Metal colli- sion: check whether the impeller and bushing are loose or worn, and re- place parts if necessary. Large outgoing grain size: adjust the belt tight- ness, control the size of the feed particles, adjust the impeller speed. Abnormal sound: check whether the bolts are loose, whether the bear- ings or gears are damaged, and repair or reptlce them in time."
