水玻璃型砂输送皮带在运行过程中,由于水玻璃的粘性作用,在型砂输送到各个造型点以后,皮带上还残存有少量型砂,因水玻璃型砂自硬较快,一般2～3小时残留型砂就能硬化.在连续造型生产的情况下,这些残型砂越积越多,从而在皮带表面上形成一层粘砂层.这种粘砂层不但很难消除,而且对生产与设备都有很大危害.1.使皮带柔韧性降低,表面易于撕裂,缩短了皮带使用寿命;2.皮带重量增加,使电机长期超负荷运行,影响电机使用寿命;3.造成皮带长期跑偏,加剧皮带的磨损;4.降低了型砂质量,增加铸件废品率;5.操作、维修工作人员工作量增大,并且停产时间增多,影响产值.
Water glass sand conveyor belt in operation, due to the viscosity of water glass in the sand after the delivery to the various modeling points, the belt still remains a small amount of sand, water glass sand faster self-hardening, usually 2 to 3 hours residual sand Will be able to harden.In the case of continuous molding production, these residual sand more piled up, so as to form a layer of sticky sand on the belt surface.This sticky sand layer is not only difficult to eliminate, but also for the production and equipment are very Big harm .1 make the belt less flexible, the surface is easy to tear, shorten the service life of the belt; 2 belt weight increase, long-term overload motor, affecting the motor life; 3 long-term deviation caused by the belt, aggravating the belt Of the wear and tear; 4. Reduce the sand quality, increase the rate of casting scrap; 5. Operation, maintenance staff to increase workload, and cut-off time increased, affecting the output value.
