🛠️ Product Overview: YT1-125/10
The YT1-125/10 is an asynchronous motor-driven hydraulic pusher. It converts the rotational energy of an electric motor into linear motion using a hydraulic pump and piston mechanism.
Primary Function: Used as the driving force for YWZ series block brakes (drum brakes) and various industrial valves or dampers.
Model Meaning (Decoding):
YT1: Series designation (Asynchronous motor type).
125: Rated thrust (Approx. 125 kgf or 1250 N).
10: Rated stroke (Approx. 100 mm).

✨ Key Features
Asynchronous Motor Drive:
Unlike the Ed series (which uses a geared motor), the YT1 series uses a direct-drive asynchronous motor with a fan impeller. This eliminates gear wear and reduces noise.
Fail-Safe Capability (Spring Applied):
While the thruster itself pushes upward when powered, it is often used in fail-safe brake systems. In these setups, the thruster's upward movement releases the brake; if power fails, the thruster retracts (via spring or gravity), and the brake automatically engages.
Compact & Integrated Design:
The motor, oil pump (impeller), and cylinder are integrated into a single casting. This makes it leak-proof and robust for harsh industrial environments.
No Oil Immersion:
The motor is sealed off from the hydraulic oil, preventing insulation degradation and extending motor life.
Adjustable Limit Switches (Optional):
You can add mechanical or induction limit switches (e.g., E1/E2 or EB types) to signal when the piston has reached the top or bottom position.
🏭 Typical Applications
The YT1-125/10 is commonly used to operate:
Brakes: Operating YWZ2, YWZ3, YWZ4 series drum brakes on cranes and conveyors.
Industrial Valves: Controlling water gates, slag gates, and dampers in metallurgy and mining.
Transmission Mechanisms: Used in various machinery requiring linear actuation.
💡 Maintenance & Usage Tips
Oil Level: Check the hydraulic oil level regularly. Use DB-25 hydraulic oil for standard temperatures. Use YH-10 aviation hydraulic oil if temperatures drop below -20°C.
Air Venting: Ensure there is no air trapped in the cylinder, as this can cause spongy operation.
Radial Load: The piston rod should not bear radial loads (side forces); it is designed for axial (push/pull) forces only.
Heater: If operating in very cold environments (< -20°C), consider ordering the model with a built-in heater to prevent oil viscosity issues.
