This instructional kit provides the necessary material for students to learn systematically how a shaft is joined to a hub or a coupler in a professional way using taper keys. The material is clearly laid out on a plastic tray. We recommend that the exercises are carried out in a workshop, as all preparations such as filing, drilling, countersinking and tapping must be carried out in a correct and proper manner by the student. The well-structured instructional material outlines all the necessary technical information and provides a step-by-step guide through the exercises.

Compact, light and suitable for use in any location, this Pull-Off Tester is fitted with a load cell and high resolution large digital display unit; it is therefore suitable for measurements from low loads up to 16 KN, granting a wide working range and ideal for a large number of applications and materials. This dynamometer measures the adhesive force and the tensile strength of two layers of materials and is particularly suitable for applications concerning testing repairs of any structure where the bond strength between two layers is an essential factor. The direct tensile force is applied by rotating the hand wheel.

The Raw Water Filtration module houses the Raw Water vessel, two independent sand filters and Filtered Water vessel. The degassed liquid is then pumped forward through the Anion Bed. The Cation Bed and Anion Bed require a regenerating every 5hours to maintain the optimum condition of the resins. Water from the Filtered water vessel is pumped forward through the Cation vessel; this then enters the degasser vessel after experiencing a carbonate removal process. Within the Acid Dosing vessel is a 5% dilution of Hydrochloric Acid, which is used to regenerate the Cation Bed. Mains water is transferred into the raw water vessel, which is then pump forward through either one of the sand filters into the filtered water vessel. On the Dosing module there is a an acid dosing vessel, caustic dosing vessel, Cation Bed, Anion Bed and Degasser vessel. In the Caustic Dosing vessel is a 4% dilution of Sodium Hydroxide; this is used to regenerate the Anion Bed.

To determine the Euler buckling load experimentally and compare it to the Euler theory.
Also to study the effect of end conditions on the buckling load.
Experiments:
Safety control using the high and low pressure switch and flow switch
Plant start-up and system monitoring using the incorporated protection and safety devices
Study and understanding of the operation of a chiller unit
On-off control of the cooled water temperature
Detecting the system operating parameters:
Calculation of thermal balances for the refrigerant and water circuit
Plotting of the refrigerant cycle on a pressure-enthalpy diagram of the refrigerant gas
The friction force is related to the roughness of the contact surface and the magnitude of the pressure, irrespective of the contact area of the friction block. The products are mainly used in exploring a simple machine is composed of a movable pulley and a fixed pulley assembly,to observe the lever balance condition and balance structure,the difference between inquiry balance and spring ergometer.

The fatigue strength and design strength of components are determined in fatigue strength tests or endurance tests. Moving components and machine parts are often exposed to periodically fluctuating loads. Even if the dynamic load is far below the static load capacity, this load can lead to fracture of the component after a long time because of material fatigue.
Features:
Automatically shuts down when the specimen fractures
Different specimens show the influence of notching and surface quality
Continuous Adjustment Of The Load Amplitude
Learning Objectives And Experiments:
Influence of different fillet radii and surface qualities on the fatigue strength
Fatigue strength of bars under reverse bending stress.
The simple heating circuit with one subcircuit contains two flat radiators and is controlled by a temperature-led controller. A three-way mixing valve is the actuator. A complete domestic heating system can be set up using the trainer together with a hot water generator, Hot water passes through the radiators and heats the room air. It contains two heating circuits. A simulator is supplied for varying the outside temperature. The heating circuit with two subcircuits contains four radiators and two heating controllers. Both heating circuits are equipped with commercially available heating technology control devices. Solenoid valves enable control of the heat distribution in the two subcircuits. Each heating circuit contains a circulating pump.
Learning objectives/experiments:
Hydronic balancing of heating circuits with multiple radiators
Function and design of commercially available heating technology components
Design of a room heating system with controller and actuator
