What is the electric hoist electronic control equipment:
Normal working conditions of electric hoist electronic control equipment: the quality of the power supply network is qualified, and the voltage fluctuation range of the incoming line does not exceed ±10% of the rated voltage value; Vertical installation, the inclination does not exceed 5 °, the installation is firm, and the horizontal movement and vertical runout relative to the main engine will not occur during the working process of the main engine.
The composition of the transmission control scheme of electric equipment must include the following necessary protection links: emergency power-off device, limit protection, loss of voltage protection, and the contactor that controls the forward and reverse rotation of the motor should have electrical interlocking and mechanical interlocking. If necessary, a mechanical interlock is also added to the button.
The structural design of the electronic control equipment and the limiter should meet the requirements of the use of the electric hoist, and the protection level of the shell should not be less than IP44 in GB/T4942.2, and the protection level of the electrical components installed in the IP44 shell is generally IP00.
The parameters of the electronic control equipment shall meet the performance requirements of the electric hoist and the provisions of the corresponding standards of the electric equipment.
The surface of the shell of the electronic control equipment and the limiter should be smooth, and there should be no obvious bursts and cracks on the edges. If the shell needs to be painted, the surface color should be uniform and consistent after painting, and the adhesion should be firm, and there should be no wrinkles, flow marks, bubbles or other phenomena.
Electronic control equipment and limiters pay attention to the surface of all ferrous metal components, accessories, fasteners, etc., which should have anti-rust protection.
The components and components selected for electronic control equipment shall meet the requirements of their respective product standards, and their rated voltage, rated current, service life, turn-on and breaking capacity, short-circuit strength performance, etc. shall meet the relevant requirements of this standard and product drawings.
