This series of hydraulic opening and closing machines for curved gates are suitable for various water conservancy, hydropower, and municipal engineering projects. This integrated opening and closing machine has a compact structure, high hydraulic transmission efficiency, low pressure loss, smooth operation, and is easy to arrange on various buildings. The double lifting point synchronization effect is good, and it is suitable for working environments with temperatures ranging from 30 ℃ to 80 ℃. No need to set up hydraulic stations and pump rooms, simple and convenient, can work on site by connecting the power supply.

There are two main types of hydraulic opening and closing machines in this series:

1. Lower hinge pivot swing structure

2. Upper suspension ear swing structure

Note: This type of gate is suitable for bidirectional waterproofing and can be opened and closed when there is a water level difference.

This series of radial gate hydraulic opening and closing machines is suitable for the opening and closing of deep hole radial gates with various orifice sizes in water conservancy and hydropower projects. The working environment temperature is -35-50 ℃, and it has good technical and economic performance such as compact main structure, high hydraulic transmission rate, smooth operation, and light weight. This series of hydraulic opening and closing machines is divided into 14 varieties, and their basic parameters are shown in the following figure. The opening speed can be specified within the range of 0.5-1.5m/min depending on the selected hydraulic pump station.

Composition of hydraulic opening and closing machine for deep hole arc-shaped door

Hydraulic opening and closing machine is a new type of opening and closing machinery that integrates mechanical, electrical, hydraulic, and instrumentation components. It is mainly composed of hydraulic cylinders, oil pumps, roughing machines, oil tanks, oil filters, and hydraulic control valves. Under the control of the hydraulic system, the inner wall of the piston in the hydraulic cylinder undergoes axial reciprocating motion, thereby driving the connecting rod and gate connected to the piston to perform linear motion, in order to achieve the purpose of opening and closing the orifice. The opening force is 2 × 60KN to 2 × 8000KN.
