Product Name: Hydraulic Expander
The working principle of the hydraulic expander is to increase the low-pressure oil pressure to several MPa through a high-pressure oil pump, so that the seal and the cylinder body generate a large contact pressure, thereby pushing the piston rod outward to achieve a strong expansion force. Specifically, the hydraulic expander consists of a hydraulic pump, a control valve, an oil pipe, a hydraulic cylinder, a piston, etc. Through the coordinated work of these components, high-pressure liquid is injected into the interior to generate the required expansion force.
Structural features
The main structure of the hydraulic expander includes:
Expansion head: used for direct expansion or tearing operations.
Expansion arm: connects the expansion head and the center lock shaft lock head to provide the necessary mechanical strength and stability.
Center lock shaft lock head: ensures stability and safety during operation.
Two-way hydraulic lock: has a self-locking function to prevent accidental retraction during operation.
Manual two-way valve and handwheel: convenient for the operator to control the expansion and closing process.
Working cylinder: stores and releases high-pressure liquid to drive the expansion action.
High-pressure hose: connects various components to ensure the smooth flow of liquid.
Operating handle: provides a convenient operation method, usually designed for both left and right hands to operate.
Application Scope
Hydraulic expanders play an important role in the following occasions:
Emergency rescue after fire fighting: used to support heavy objects, separate clamping, and pull various material structures and objects.
Emergency rescue after earthquake disasters: can quickly move and lift obstacles, pry open gaps and expand them into channels, deform metal structures, and tear steel plates on the surface of the car body.
Handling of road traffic accidents: used to quickly open flattened car doors and other narrow spaces.
Large-scale demolition operations in industrial production: such as pipeline inspection and maintenance, large-scale mechanical flange connection disassembly and maintenance, etc.
Features
Hydraulic expanders have the following significant features:
Made of high-strength lightweight alloy steel: light weight, but large expansion force, suitable for high-load rescue operations.
Quick response: short opening and closing time, able to quickly complete tasks in emergency situations.
High safety: a combination of a two-way hydraulic lock and an automatic reset control valve, with a self-locking function, ensures safe operation.
Wide applicability: can be used with a traction chain, and can also operate efficiently in narrow spaces.
In short, hydraulic expanders play an important role in various emergency rescue and industrial production with their powerful functions and flexible usage. Their high efficiency and safety make them one of the indispensable rescue tools.
Mode of transportation: water transport, land transport, air transport, express delivery, logistics.
