Refrigerator Unit Model consists of arefrigeration chamber with a heater as cooling load, evaporator, fan andvarious expansion elements. The fan supports the achievement of an eventemperature distribution in the chamber. Refrigerator Unit Model is part of the HSI trainingsystem for refrigeration and air conditioning technology. In combination withthe base unit HSI training system refrigeration and air conditioningtechnology, base unit the operational model of a domestic refrigerator iscreated. Solenoid valves enable the operation of the systemwith capillary tube or with expansion valve. All components are clearlyarranged on a panel. The model is plugged onto the base unit, secured using fasteners andconnected with refrigerant hoses to become a complete refrigeration circuit. The softwareoffers the option to simulate faults. Temperaturesand pressures in the system are recorded by sensors and displayed dynamicallyin the software. A cooling load can additionally besimulated with the heater. The operation of individual system components, here the temperature control, fan, heater, compressor and solenoid valves, takes place via the software. The effect of parameter changes can be tracked online in thelog p-h diagram.

A versatile regenerative enginetest set with comprehensive controls and instrumentation. When used with one of optional single-cylinder engines, it safely and effectively enables study and demonstrations of the features and characteristics of the engine. Using this enables accurate real-time data capture, monitoring and display, calculation and charting of all relevant parameters on a computer making tests quick and reliable. In addition,optional ancillaries are available to extend the range of study, demonstrations and investigations even further. The equipment is fully compatible with Versatile Data Acquisition System.
The main components of the system are:
A fuel tank support frame that supports the fuel tank and optional fuel gauge
A heavy fabricated floor-mounting bed
An instrument console with instrument frame
The bed is held on anti-vibration mounts. It includes a robust trunnion-mounted d.c. machine. When the engine is initially mounted onto the test bed or exchanged with an alternative engine, dowels and slots locate the engine quickly, accurately and reliably. An electronic load cell connected to the machine measures the driving torque of the test engine. The engines are supplied pre-mounted on a sturdy precision base plate. Each engine includes a colour-coded fuel tank with self-sealing couplings.
Safety Features:
Emergency stops on test bed and console
Interlocks for mains power failure and engine over speed.

Wrapped around the circumference of each step of the shaft is cord. At the ends of each cord is a single adjustable bob. The stepped shaft is secured to a main shaft, which itself is secured within a bracket. The bracket can be bench or wall mounted. Alternatively the starting position of each bob can be made different. The adjustment of the bobs can be made to ensure that the starting positions of each bob is the same even though the steps are different diameters.
Experimental Capabilities:
Compare actual results with theory
To find the relationship between angular rotation and the peripheral movement of the stepped shaft.
This Series creep testing machine applies advanced servo motor and ball screw actuator which assure loading conveniently and simply. The drive system comprises a printed circuit motor with toothed belt and gearbox to the recirculating ball screw actuator.
Control system owns the three closed control function as load control, extension control, and velocity control. High precise control and accurate load with load measurement resolution reach 1/300000; the loading testing curve can be plotted automatically.
Numerous high temperature pull rods, specimen holders, furnace systems and extensometers available for creep and stress Relaxation applications. Many of which are also adaptable to hot tensile testing applications on universal testing machines.
Motorized draw-head assembly automatically compensates for specimen elongation and keeps loading bar with excellent load accuracy of +/- 0.5% guaranteed.
Both room temperature and elevated temperature systems are available
