Hydraulic switches (hydraulic control switches), as the name suggests, are widely used in equipment and machinery that require hydraulic systems for power transmission, position control or pressure regulation.
The following are the common application fields and products of hydraulic switches:
1. Construction machinery excavator: Controls hydraulic actions such as bucket, boom, and rotation.
Loader: Manage the lifting and tilting of the bucket.
Bulldozer/roller: Adjust the hydraulic pressure of the bulldozer blade or vibrating wheel.
Forklift: Controls the lifting and tilting of the forks.
2. Agricultural machinery
Tractors: Lifting plows, harrows, seeders and other agricultural tools (through hydraulic suspension systems).
Combine harvester: Adjust the height of the header and hydraulically control the unloading of the grain silo.
Sprayer: Controls the expansion and retraction of the spray rod.
3. Industrial equipment
Hydraulic press: Controls the pressure and stroke for actions such as stamping and forming.
Injection molding machine: Manage the opening and closing of molds and injection pressure.
Machine tool: Used for hydraulic clamping and tool changing systems.
4. Transportation
Trucks/dump trucks: Control the lifting of cargo boxes (such as dump trucks).
Ships: steering gear hydraulic system, hatch cover switch.
Aircraft: Landing gear retraction and extension, flap control (some models use hydraulic control).
5. Construction and municipal equipment
Lift platform/aerial work platform: Adjust the extension and retraction of the boom and the height of the platform.
Pile driver: Control the impact frequency of the hydraulic hammer.
Fire engine: Aerial ladder lifting, water cannon Angle adjustment.
6. Other special applications
Mining machinery: Hydraulic supports, control of tunnel boring machine tools.
Wind power equipment: Hydraulic braking system.
Military equipment: Tank turret rotation, armored vehicle suspension adjustment.
# Key Role
The core functions of hydraulic switches are safety control and precise operation, for example:
Prevent system overload (pressure switch).
Realize the automated process (solenoid valve +PLC control).
Energy conservation (such as the on-off regulation of load-sensitive pumps).
