🛠️ Product Overview: DYTZ2550-350-90
The DYTZ2550-350-90 is an Integral Straight-Type Electro-Hydraulic推杆 (Thrustor/Actuator). It is a self-contained unit that combines a motor, hydraulic pump, and cylinder in a straight-line configuration.12
Note on Nomenclature: While you might be looking for a "pusher" (pusher rod), in industrial terms, this is classified as a linear actuator or thruster. It differs from the Ed/YT series pushers which are typically used to release brakes; this unit is used for general linear pushing/pulling tasks.
Model Meaning:
DYTZ: Integral Straight-Type Electro-Hydraulic推杆.
2550: Rated Thrust (Approx. 2550 daN / 25 kN).
350: Stroke Length (350 mm).
90: Rated Speed (90 mm/s).

✨ Key Features
Integral (Monoblock) Design:
The motor, pump, and cylinder are integrated into a single unit. This makes it leak-proof and very compact compared to systems with separate power packs and hoses.
Bidirectional Operation:
Unlike some pushers that are spring-return, this unit uses hydraulics for both push and pull. It can generate force in both directions (Push Force: 2550 daN, Pull Force is typically slightly less).
Overload Protection:
Built-in hydraulic relief valve protects the system from damage if the load exceeds the rated capacity.
Self-Locking:
When the motor stops, the hydraulic oil locks the piston in place (pressure self-locking), holding the load steady without drifting.
Adjustable:
It features limit switches for position control and can have flow control valves installed to adjust the speed.12
🏭 Typical Applications
The DYTZ series is widely used across 18 industrial sectors:
Metallurgy & Mining: Slag door control, material blocking.
Cranes & Conveyors: Feeding mechanisms, stoppers.
Power Plants: Dampers and valve actuators.
Port Equipment: Cargo handling locks.
💡 Maintenance & Usage Tips
Hydraulic Oil: Use HM46-68 hydraulic oil. Check the oil level regularly and change it every 6-12 months depending on usage.
Mounting: Ensure the mounting brackets have sufficient clearance for the full 350mm stroke.
Insulation: Regularly check the motor winding insulation resistance, especially if used in humid environments.
