SD-ZNP-10000 Liquid A Sample Packing Service Test Utility

This testing machine is produced and manufactured using electro-hydraulic servo technology. It employs an electro-hydraulic servo linear actuator as the force application method, transferring torque to the test sleeve via a force arm to complete the main components of the torsional fatigue test, such as the following:

Section 1:

1. Constant pressure variable frequency servo pump station increases flow rate. Equipped with an oil-cooled unit.

2. Four-poster vertical main unit, actuator vertically positioned, temperature and humidity environment chamber side door for easy sample loading:

3. Linear Actuator with 10KN Servo Valve, Load Sensor, and Travel Gauge

4. Pipe and Fitting Components

5. Control Systems and Computer Software

6. Necessary workwear and fasteners

II. Explanation of Main Technical Parameters:

1. Actuator: The servo actuator with unified, standardized, and modular design features low damping, high responsiveness, long lifespan, and a large gap design.

1.1 All sealing elements of the servo actuator are made of imported high-speed sealing elements specifically for servo actuators.

1.2 The servo actuator piston rod support breaks the traditional design, utilizing non-metallic support and large gap design, featuring high-speed, non-caking, and self-lubricating properties.

1.3 Designed with a hydraulic cushioning zone at the amplitude limit position of the servo pendulum actuator to prevent damage from uncontrolled operation.

1.4 Configuration of dedicated high-response servo valve for dynamic testing machine

1.5 Displacement sensor for measuring displacement.

2. Variable Frequency Servo Pump: Equipped with an oil-cooling unit, capable of reducing energy consumption.

2.1 The pump station features an elevated motor-mounted structure, offering a compact design. It is equipped with a low-noise, variable-frequency servo motor and a straight-coupled, internal meshing gear pump. 2.2 The features of the straight-coupled, internal meshing gear pump: Known as the "wear-free oil pump" in the hydraulic industry, it is used in high-end, precision, and advanced hydraulic systems. Compared to vane pumps and plunger pumps, the straight-coupled, internal meshing gear pump boasts superior performance, including low noise, non-pulsating, and long service life.

2.3 Low Noise: The straight-line internal gear pump boasts exceptional characteristics with its special gear design, featuring a straight gear profile and a straight involute profile of the gear ring. It operates with minimal trapped oil areas, maintaining a stable and peaceful audio even at high speeds.

2.4 Longevity: The long service life of the inline gear pump with integral meshing gears is due to its durability. An oil film protective layer exists between the internal mechanical surfaces and functional parts, resulting in minimal wear. Even when using general hydraulic oil, the components are not easily worn out. Additionally, by employing the principle of double-stage pressurization to bear pressure differences, the working conditions of the pump are improved while increasing the working pressure, thereby extending the pump's service life; a high and low-pressure soft switching hydraulic module composed of a main overflow valve, accumulator, secondary main overflow valve, secondary overflow valve, and directional valve, and a domestically produced Wenzhou Liming precision oil filter with no more than 3u. 2.5 Oil-cooled, no need for additional cooling water, easy to use:

2.6 Imported German High-Pressure Hoses; Double Electric Contact Temperature Controller; Level Controller; featuring oil temperature (below 10°C, above 55°C), level, filter oil clogging alarm or stop function.
