YT1-125Z/10 Electro Hydraulic Thrusters

YT1-125Z/10 electro hydraulic thrusters

 

The YT1-125Z/10 is a medium-duty Electro-hydraulic Thruster (also known as a Power Hydraulic Push Rod). It is a compact drive unit that integrates a motor, centrifugal pump, and oil cylinder to generate linear motion and force. It is primarily used as the actuator for industrial braking systems (such as the YWZ series) and valve operations.

The model number breakdown is as follows:

YT1: The series designation for standard Electro-hydraulic Thrusters.

125: The Rated Thrust of 1250 N (approx. 125 kgf).

Z: Indicates the design variant (often related to the connection type or specific mounting configuration).

10: The Nominal Stroke of 100 mm.

💡 Key Features & Characteristics

Integrated Mechanism:
The unit combines a drive motor and a centrifugal pump. When energized, the motor spins the impeller, creating hydraulic pressure that pushes the piston and rod upward. When power is cut, the piston returns via gravity and the return spring of the connected brake.

Technical Standards:
The YT1 series is manufactured in compliance with the technical standard JB/T10603-2006, and its connection dimensions conform to JB/T7021-2006, ensuring interchangeability with compatible brakes and valves.

Motor & Protection:

Insulation: Class B (suitable for temperatures up to 130°C).

Protection Rating: IP54, providing protection against dust and water splashes, making it suitable for industrial environments.

Power Supply: Standard AC 380V / 50Hz (3-Phase).

High Frequency Operation:
Designed for frequent start-stop cycles, with a rated operating frequency of up to 600–720 cycles per hour.

Compact & Maintenance-Free:
The unit is self-contained with no external hydraulic lines. It uses high-quality hydraulic oil (typically DB-25) sealed within the unit.

🏭 Typical Applications

The YT1-125Z/10 is widely used in起重 (lifting), transportation, and metallurgical machinery:

Brake Actuation: It is the standard actuator for YWZ series electro-hydraulic block brakes.

Industrial Valves: Used to drive gate valves, slide gates, and other flow control devices requiring linear motion.

Clamping Devices: Used in various jig and fixture applications for clamping workpieces.

Sectors: Cranes, hoists, mining machinery, and port equipment.

📋 General Technical Specifications

Note: The YT1 series is a widely used standard in China. While similar to the newer Ed series, the YT1 is often distinguished by its specific mounting dimensions and older design heritage. When replacing an Ed thruster with a YT1, always verify the mounting hole spacing and thrust/stroke match your application.
