Electric device hoist
The working principle of the electric hoist is that the hoist drives the hoist nut to rotate, and under the action of the trapezoidal thread, the screw rod drives the weir gate body to run up and down, so as to cut off or dredge the water flow. It has the functions of light weight, flexible operation, anti-corrosion, no rust, convenient installation and maintenance, and reliable sealing. Engineering, used as cut-off, regulating flow and controlling water level. The regulating weir gate is generally installed on the upper part of the pool to adjust the water level in the pool, such as the distribution well of the aeration tank or some water outlets.
Hoist
The hoist is mainly composed of motor, deceleration device and weir door assembly. The motor drives the screw rod on the upper part of the weir gate through the deceleration device. Through the vertical displacement of the screw rod, the weir gate is pulled by the hinge machine to change the angle with the liquid surface, so as to achieve the purpose of changing the water level and controlling the flow.
The features of hoist
1. Flexible action, good sealing performance and high degree of automation.
2. Good adaptability to working environment and long service life.
3. Equipped with stroke limit and power overload protection, safe and reliable work.
4. It is easy to combine structures, easy to install and maintain.
The role of electric hoist
The electric hoist is mainly used to control the lifting of various gates, weir gates and valves, so as to realize the opening and closing of gates or valves. It is generally divided into manual and electric control. When the gate or weir gate has a large ratio of width to height, a double lifting point hoist is required.
When installing the electric hoist, it is necessary to keep the foundation layout plane of the base at 180o; the contact area between the hoist base and the foundation layout plane must reach more than 90%; the screw axis must be perpendicular to the horizontal plane measured on the gate platform; it must be hung with the gate The earholes are aligned and vertical to prevent the screw from tilting, causing local stress and damage to the machine.
Place the manual electric hoist at the installation location. Put a limiting disc on the screw rod, screw the screw rod into the machine from the lower part of the beam, when the screw rod is exposed from the top of the machine, cover the upper limiting disc again. The bottom of the screw rod is connected with the gate.
The foundation for installing the hoist must be solid and safe. Concrete for machine base and basic components shall be poured according to the drawings. When the concrete strength does not reach the design strength, it is not allowed to dismantle and change the temporary support of the hoist, let alone carry out trial adjustment and trial operation.
During installation, according to the lifting center line of the gate, find the center so that the vertical and horizontal center line deviation does not exceed plus or minus 3mm, and the elevation deviation does not exceed plus or minus 5mm. Then pour the second-stage concrete or connect with the embedded steel plate.
The installation of the electrical equipment of the product must comply with the requirements of the drawings and instructions, and all electrical equipment must be reliably grounded.
After the product is installed, it is necessary to clean the machine, repair the damaged protective paint, and inject grease.
