Gate opening and closing hydraulic system

I. Product Overview

The Gate opening and closing hydraulic system is a power control system designed specifically for water conservancy projects such as sluices, ship locks, reservoirs, and power systems. It uses hydraulic actuation to precisely raise, lower, position, and lock gates, offering high load capacity, high reliability, and remote automated control capabilities.

II. System Components

Hydraulic Power Unit

· Motor-Diesel Engine Pump Unit: Provides stable hydraulic oil flow and pressure.

· Oil Tank: Equipped with level and temperature sensors and a filter to ensure oil cleanliness.

· Control Valve Assembly: Includes directional valves, relief valves, and counterbalance valves to adjust opening and closing speed, direction, and pressure.

Actuator

· Hydraulic Cylinder: Double-acting or single-acting cylinders with corrosion-resistant design and customizable stroke.

· Synchronizer (Multi-Gate Interlocking): Ensures synchronized operation of multiple cylinders with an error of ≤2%.

Control System

·PLC Intelligent Controller: Supports manual, automatic, and remote control (compatible with SCADA systems).

· Sensors: Real-time monitoring of gate opening, oil pressure, flow rate, and other parameters.

· Emergency Devices: Backup power supply and manual pump ensure emergency opening and closing in the event of a power outage.

Auxiliary Components

· Piping and Fittings: High-pressure stainless steel piping with leak-proof design.

· Accumulator: Sudden pressure compensation, reducing frequent pump starts and stops.

III. Product Features

High Load Capacity

·Design pressure ranges from 21-35 MPa, suitable for applications ranging from small channel gates to large dam crest gates (with opening and closing forces of hundreds of tons).

Precision Control

·Opening accuracy of ±1 mm, supports stepless speed regulation and hovering at any intermediate position.

Environmental Adaptability

· Anti-corrosion treatment (such as hard chrome plating and stainless steel construction) ensures suitability for harsh environments such as humidity, high salt spray, and low temperatures (-30°C).

Safety and Reliability

· Multiple Protections: Overload protection, hydraulic lockout, and explosion-proof valves prevent gate loss of control.

· Redundancy: Dual backup of key components, with a failure rate of <0.1%.

Energy Saving and High Efficiency

Variable displacement pump + load-sensing technology reduces energy consumption by over 30%.

IV. Application Scenarios

Water Conservancy Projects: Reservoir spillways, irrigation channel gates.

Hydropower Plants: Inlet rapid emergency gates.

Shipping: Lock miter gates and lifting gates.

Environmental Protection: Sewage treatment plant trash rack opening and closing.

V. Technical Advantages

Customized Design

· System parameters are matched based on gate type (flat gate, curved gate, etc.) and operating conditions (static and dynamic water opening and closing).

Intelligent Operation and Maintenance

· Supports IoT remote diagnosis and real-time fault warnings.

VI. Service Support

Pre-sales: Operating condition analysis, schematic design, and 3D modeling.

After-sales Service: Installation guidance, commissioning training, and lifetime maintenance.
