It is well known that during the casting process, the temperature of the casting material is too high, which will cause the sand particles to expand, which may deform the casting and affect the quality of the casting. The vacuum negative pressure system is the main core equipment of the dry sand negative pressure casting process. The sand is solid and solid. If the casting uses lost foam, it will produce gasification. The vacuum negative pressure system can pull the lost foam gasification product out of the cavity in time to ensure the soundness of the casting. The early vacuum negative pressure system was mainly separated and extracted vacuum. The pipeline resistance is large, the use efficiency is low, the negative pressure control is cumbersome, and the voltage stabilizing effect is poor. Qingdao Sanzhuji Equipment Manufacturing Co., Ltd. combined with customer needs and industry experience, changed the vacuum negative pressure system from the original separation type to the overall combination type, and named it zk series vacuum negative pressure system. The system is simple and compact in structure and easy to install and maintain It is convenient to change the extraction resistance of the original pipeline and improve the efficiency of the equipment. At the same time, an independent negative pressure control cabinet is used to make the negative pressure unit generate vacuum according to the requirements of the casting process of the casting, and the negative pressure distributor is used to reduce the negative pressure. The vacuum generated by the unit is reasonably distributed, and then distributed to each vacuum point that requires vacuum. The system is economical and practical. The structure is simple and compact. It has functions such as pressure stabilization, gas filtration, oil gas separation, and steam water separation. It can also be used for other Industries that need to draw a vacuum. Welcome to the factory to visit and purchase.
