DYT Series Electro-hydraulic Pusher: Installation Methods & Matching Accessories

 

1. Installation Methods

DYT series electro-hydraulic pushers are linear drive actuators widely used for gate opening/closing, baffle adjustment, conveyor tensioning and auxiliary brake actuation. Horizontal mounting is the standard layout, vertical upward/vertical downward inclined installation can be customized per site conditions. Mounting lugs conform to general industry connection dimensions for convenient interchange.

Standard Horizontal Installation

Secure the front hinge base and rear mounting support to rigid fixed frames with high-strength anti-loose bolts. Ensure the central axis of the pusher piston rod is horizontal without bending or offset stress.

Connect the front end of the push rod to the driven equipment hinge joint via pin shaft; leave reasonable stroke margin to avoid mechanical top dead point impact or insufficient travel.

Arrange the motor housing on the upper side of the cylinder body to ensure the built-in hydraulic oil fully immerses internal pump and transmission parts, preventing air trapping and slow response.

Reserve sufficient space around the cylinder for oil filling, seal replacement and stroke maintenance inspection.

Optional Vertical & Inclined Installation

Vertical upward mounting: Add auxiliary oil retaining baffles inside customized oil tanks to avoid oil starvation during operation.

Vertical downward / inclined mounting (≤75° tilt angle): Must select DYT special tilted version; standard horizontal DYT cannot be installed upside down directly, otherwise internal parts will suffer dry friction damage.

After non-horizontal assembly, recheck the oil level against the sight glass mark and supplement dedicated hydraulic oil as required.

Core Installation & Commissioning Requirements

All hinge pin joints are equipped with self-lubricating sleeves; apply lithium-based grease during assembly.

Before power test, fill specified anti-wear hydraulic oil to the calibrated liquid level on the sight glass; overfilling or underfilling causes jitter and abnormal noise.

Install travel limit switches at both full extension and full retraction positions to realize stroke protection and position feedback.

Standard power supply: AC380V; AC220V single-phase motor variants are available for small-size models.

Isolate the motor cylinder from splash water, heavy dust and corrosive gas to extend coil and seal service life.

Do not apply lateral radial load on the piston rod during operation to prevent rod bending and seal abrasion.
