Arc-shaped hydraulic gate hoist

The arc hydraulic gate hoist is a specialized hydraulic operating device designed for controlling the opening and closing of radial gates. Its core features and working principles are as follows:
Core Components
Composed of a hydraulic system and hydraulic cylinders, it uses oil pressure to drive pistons for gate lifting and lowering control. The system includes an oil tank, oil pump motor unit, control valve assembly, and stroke detection device, supporting synchronous control of dual cylinders. ‌
Working Principle
An electric motor drives the oil pump to output pressurized oil, which is directed through valves into the hydraulic cylinders to push the piston rods for linear motion, thereby opening or closing the gate. The system features stroke detection and synchronous control, ensuring collaborative operation of multiple cylinders with a deviation of ≤10mm. ‌
Applications
Suitable for radial gates in hydraulic engineering projects, such as reservoirs, river regulation, and ship locks. It supports high-pressure conditions (up to 19MPa) and extreme temperature environments (-35℃ to 80℃). ‌
Key Technologies
‌Dual Pump Backup Design‌: Enhances system reliability and prevents shutdowns caused by single pump failure.
‌Synchronous Control Algorithm‌: Adjusts cylinder pressure in real-time via sensors to ensure synchronized gate rotation.
‌Leakage Compensation‌: Employs pressure compensation technology to maintain system stability.
‌Safety Protection‌: Automatic reset for excessive gate lowering and overload protection with relief valves. ‌
Routine maintenance includes regular replacement of hydraulic oil, cleaning of filters, and calibration of verticality and horizontal deviation to ensure operational accuracy.
