WE Series Worm Gear Drive Dial Type Hydraulic Universal Testing Machine

1. Usage
The WE series dial type hydraulic universal testing machine is manually controlled. The dial of its dynamometer shows testing force. The product can be used in tensile, compression, bend or shear test on metallic materials. In terms of adjusting test space, it may fall into worm drive and chain drive. Measurement ranges of testing force are 100kN, 300kN, 600kN and 1000kN.

3. Functions and Characteristics of Hydraulic Universal Testing Machine
1) Main Engine
a) With hydro-cylinder underneath, the structure is compact and reasonable. It considerably reduces the height of the machine without changing test space, compared with the one with hydro-cylinder overhead.
b) Adopting worm drive mechanism with crosswise moving beam to adjust test space, instead of chain drive mechanism, the product allows adjusting test space with no need for screw rotation. Its drive system is completely separated from positioning system, and the geometric center of loading system is identical to the center of stressed position, which guarantees coaxiality between upper and lower jaws, and durability of the main engine.
c) The independent hydraulic clamping mechanism ensures reliability of clamping system. Even though the sample is snapped, it will not drop or hurt testers.

2) Dynamometric System
a) The dynamometer and main engine are independent of each other, and connected to one other by a fuel injection pipe and wires. Such a design avoids any influence upon the reading of dynamometer from great shock caused by sample snapping, which makes sure the reading is accurate and reliable.
b) The dial for indicating testing force comes with closed structure and clear ruling.
c) Equipped with a loading speed indicator, the product is easy to operate and able to reach 0.4rpm, 0.8rpm or 2 rpm.

2. Functions and Characteristics of Dial Type Hydraulic Universal Testing Machine
1) Main Engine
It belongs to chain drive method.

2) Dynamometric System
a) The dynamometer is independent of the main engine. They are linked by a fuel injection pipe and wires to protect the reading of dynamometer from being affected by great shock when the sample snaps. Therefore, the reading can be precise and reliable.
b) With clear scale, the dial for indicating testing force adopts closed structure.
c) Its loading speed indicator is conducive to easy operation. Optional speeds are 0.4rpm, 0.8rpm or 2 rpm.
