Yangtze River double lifting point hoisting hoist

Yangtze River double lifting point hoisting hoistWorking principle: The machine adopts YZ series electric motors. When the hoist is working, the electric motor must reverse the rotational force, which is transmitted through the coupling to make the steel wire rope retract or release in the spiral groove, so that the gate can be raised and lowered to achieve the effect of opening and closing. The AC brake can keep the gate in any desired position. The leakage automatic device can automatically leak electricity when there is a leakage fault in the circuit, thus protecting the hoist. After the fault is eliminated, it can operate normally. Flat sliding steel gate is a commonly used water blocking and sealing equipment in water supply and drainage engineering, water conservancy, and hydropower engineering. It consists of components such as door frame, gate plate, sealing ring, and adjustable wedge pressure block. After long-term wear and tear, the sealing surface of the steel gate can be adjusted by wedge-shaped pressure blocks to ensure normal operation. The steel gate is made of high-quality steel plate as the base material, and is coated with rubber water stop and anti-corrosion methods for sandblasting, rust removal, and hot spraying of zinc on the surface. The steel gate has a reasonable and sturdy structure, strong wear and corrosion resistance, and reliable performance; Easy to install, adjust, use, and maintain.

Yangtze River double lifting point hoisting hoistDebugging of the opening and closing machine:
1. When the hoist is unloaded, ensure that the three-phase current imbalance does not exceed plus or minus 10%, and measure the current value.
2. Adjustment of upper and lower limits: When the gate is fully closed, press the upper limit switch tightly and fix it on the screw. When the gate is fully open, press the lower limit plate down on the travel switch and fix it on the screw.
3. The adjustment of the main controller of the hoist must ensure that the error of the gate lifting to the upper and lower limit positions does not exceed 1cm
4. After installation, it is necessary to conduct a trial run. First, conduct a no-load test by letting the screw travel twice and listening for any abnormal sounds to check if the installation meets the technical requirements. Conduct a load test, perform two strokes under rated load, observe the operation of the screw and gate, and check for any abnormal phenomena. Only after confirming that there are no errors can it be officially put into operation.
