Ring electric hoist loading test system hardware design
Ring loading test system hardware design of the electric hoist lifting equipment manufacturing industry in our country, the electric car type ring chain manual hoist hoist electric hoist limit load point of the system mainly includes a hydraulic loading system (hereinafter referred to as ring electric hoist) is a new kind of small-sized lifting products, it has a volume and a single-chip microcomputer control system. Small, light weight, high strength, appropriate price etc, especially suitable for low building height as shown in figure who, hydraulic test system for limit load experiment, the hoist equipment pressure under the small flow pump and the space is lesser workplaces of lifting and handling operations. Work, overflow valve manually adjusted to the rated pressure, according to two different series of common inspection method on the properties of ring electric hoist crane is mass loading the product choose three four-way valve gate, the overflow valve pressure oil flow method, which includes static and dynamic load of two processes: a pilot proportional relief valve. In ring electric hoist is not ascension, limited to the products tested to 1.5 times the rated load experiment belongs to dynamic loading, the loop electric hoist ascends, conditioning section leads people weight blocks, the quality of stay for a few minutes, to determine its static performance. Proportional relief valve from the rated load strength, step by step until the ring electric hoist electric hoist inner ring.
