2/3/5/12/15-ton Manual Digital Hydraulic Laboratory Press YP-S

Manual Digital Hydraulic Laboratory Press

YP-S series manual digital display hydraulic press 2-15 tons, adopts double column design, suitable for small mold pressing or occasions with small tonnage requirements but strict pressure accuracy requirements.

Key Performance Features

• Pressure range: 0–15 tons (0–33 MPa).

• Cylinder diameter: 75 mm; piston travel: 32 mm.

• Table diameter: Φ80 mm, with an effective workspace of 92 × 130 mm.

• Pressure stability: ≤ 1 MPa over 10 minutes. Accurate readings through the DDNT digital sensor display, switching between tonnage (T) and MPa, resolution 0.01 T.

• Compact footprint: 230 × 160 × 385 mm, weight approx 28 kg. Perfect for labs where space is limited.

Product Architecture & Component Breakdown

• Main Lead Screw: Precision-threaded vertical screw for stable mold positioning and secure clamping.

• Top Handwheel: Ergonomic top handle for effortless manual adjustment of the lead screw.

• Guidance Pillar: High-strength support columns ensuring structural rigidity and uniform force distribution.

• Working Workspace (Workbench): Flat, heavy-duty pressing table designed to accommodate various laboratory sample molds.

• Digital Pressure Indicator: High-precision LCD digital readout displaying real-time pressure values.

• Hydraulic Operation Handle: Smooth manual lever pump for stable and controlled pressurization.

• Reservoir Cover: Sealed cap for the internal hydraulic oil tank to prevent contamination.

• Release Valve Stem: Precision rotary valve for safely venting and releasing system pressure.

• Eccentric Shaft: Core internal drive mechanism for the hydraulic pumping system.

Step-by-Step Operating Guide

• Step 1: Mold Positioning — Center the sample mold precisely onto the lower platen/workspace of the hydraulic press.

• Step 2: Valve Sealing — Rotate the release valve stem clockwise to fully seal the hydraulic circuit.

• Step 3: Screw Securement — Turn the top handwheel downward to lower the lead screw, securely clamping the mold in position.

• Step 4: Pressurization — Pump the operation handle back and forth smoothly until the digital indicator reaches your target pressure.

• Step 5: Pressure Release — Slowly turn the release valve stem counterclockwise to safely vent and release the system pressure.

• Step 6: Sample Extraction — Retract the lead screw and carefully retrieve the processed mold for sample analysis.
