Product Overview: Drop Hammer Test Equipment

The Drop Hammer Test Equipment is a precision impact testing system engineered to evaluate the impact toughness and fracture properties of engineering materials. Based on the round-robin method for determining the external impact resistance of thermoplastics pipes, it delivers reliable, repeatable data for material performance evaluation and product quality validation across industrial sectors.

The tester is purpose-built for assessing the external impact strength of thermoplastic pipes, plastic sheets, and non-metallic specimens, making it a core apparatus for product qualification inspection, quality management, and reliability validation.

Compatible Pipe and Material Types

The instrument supports an extensive portfolio of plastic pipe products, including but not limited to:

PVC-U water supply pipes
Low-pressure water delivery pipes
Core-layer foamed pipes
Double-wall corrugated pipes
Carat pipes
Steel strip reinforced pipes
PE water supply pipes
MPP power protection pipes
Hollow wall winding pipes
CPVC power pipes
Rigid plastic sheets and other non-metallic specimens

Instrument Features and Design Advantages

1. Three-Tier Safety Protection Architecture

A multi-stage interlock protection framework safeguards the operator throughout testing:

Tier 1: Interlock protection for the sample access door
Tier 2: Interlock protection for the viewing window
Tier 3: Upper and lower limit position protection

2. High-Speed Lifting Capability

Driven by a high-torque stepper motor, the unit achieves a lifting velocity of up to 250 mm/sec, raising the hammer from the starting point to the 2-meter height within 8 seconds. This significantly shortens test duration and boosts operational efficiency for high-volume sample testing.

3. Intelligent Hovering Capability

A multi-segment speed regulation algorithm enables smooth deceleration and pinpoint hammer positioning without offset. The control logic eliminates inertial displacement, maintaining uniform test conditions and securing excellent repeatability of measured data.

4. 3D-Optimized Drop Hammer Guide Tube

The guide tube is refined through 3D modeling and fitted with vent holes to reduce air resistance during the hammer fall, stabilizing impact force transmission. Hoop reinforcing structures prevent deformation and structural damage, strengthening long-term dependability under rigorous test conditions.

5. Pneumatic Hammer Hoisting and Triggering Assembly

Unlike conventional electromagnetic hammer structures, this tester uses a high-output pneumatic setup for enhanced performance:

300N long-stroke double air cylinder for steady, powerful actuation
Rubber tendon plate hammer face for stable impact without damaging specimens
Pneumatic lifting and release design resolves typical electromagnetic drawbacks such as cable bending, wire fracture, and electric leakage
Built-in pneumatic auto-locking system for higher safety and operational stability

6. Integrated Modular Construction Design

Mechanical section: Standardized aluminum alloy profiles support standardized fabrication and modular installation, delivering lightweight yet high mechanical strength.

Electrical control system: A 7-inch touch screen paired with a Delta PLC provides intuitive operation, stable running performance, and simplified maintenance.
