The new hoist, hoist, Xinhai Metallurgy

 Vertical hoist can start the process of starting current control: setting value of the current relay pull hoist motor switching torque corresponding upper limit value corresponds to the release of the lower limit switch torque. In the main stages of the acceleration torque switching upper and lower limits, like, so use a current relay can control the entire acceleration process. However, when the load is reduced, improve acceleration will increase, unsafe operation, when the load increases, the starting time extension, reduce skills. Vertical hoist can be supplemented by the current time-based control of the starting process: In order to overcome the time and ask, or by simply controlling the current shortcomings of the main shaft hoisting system is often used to control the main principles of the current time supplemented. Since the current control according to the same time there. Time control section, when the load changes designed to maintain approximately constant acceleration. But a lot of the load decreases when the hoist, the acceleration will be great, the motor operating point in a very short period of time up to the high speed, torque is small at this point, even when asked relay, but the current is too small, current relay can not pull, the control system automatically transformed into a pure time control. Due to the time the relay is supplemented by the principle of time tuning hoist prices, total delay time is shorter, so the auxiliary shaft lifting personnel hoisting system can not use this control method. Feed hoist is a special hoist equipment, which is mainly used for feed delivery, high working efficiency, smooth operation and long life. It may be the speed adjustment during transport, flexible operation. It mainly consists of transmission equipment, control some devices, stents and other components. Its use reduces the manual labor intensity hoist model, changed the traditional delivery model to improve the efficiency of the production of highly efficient elevator, is a widely used machinery and equipment. When the equipment is installed to be installed by a professional staff, after installing the equipment to conduct the test run to ensure that the equipment is in normal circumstances, during the formal delivery of the feed, the feed to be shipped within the specified range transport, non-overloading make use . Feed confidential upgrade equipment regularly inspected and maintained, not only to extend the life of equipment, but also to ensure the safety of staff.
