A bench top service unit makes it possible to supply hot water to different types of heat exchangers which are small scale versions of the commonly used industrial ones. The Computerized Heat Exchanger Bench Top Study Unit has been designed to carry out experiments concerning the main techniques of heat transfer. Thus the student can compare their performance, fully understand the importance of a correct choice and, if possible, compare the influence of co-current and counter-current heat exchange.

The super Heater included in the set is a heat exchanger ensuring the complete evaporation of the refrigerant before entering the compressor whilst the liquid refrigerant is supercooled upstream of the expansion element. The set includes simple refrigeration components, such as expansion elements and filters, as well as electrical components, e.g. switches and thermostat. Via pressure and temperature measurements the change of state of the refrigerant can be tracked and entered. The temperature is measured by interlaboratory thermometers. The control behaviour of the expansion element is monitored at the flow meter. Manometers provide an insight to the pressure ratios in the refrigeration circuit.

PLC Controlled Pneumatic And Hydraulic Training Device uses a dedicated independent hydraulic test pump with variable speed DC motor system with oil pressure setting function. Oil lap using quick-change connectors; convenient disconnect without leakage. With this set of training equipment, you can do pneumatic control and hydraulic control circuit and its corresponding basic application experiments. You can set safe working pressure of output oil pressure. With all common hydraulic components: Each hydraulic component is equipped with mounting plate, which can be easily and freely placed in the aluminum alloy hydraulic components on the panel (the panel with T slot in the form of aluminum alloy structure). It can also be integrated with each other to carry out the following experiment: realized pneumatic - electric control, pneumatic hydraulic control, electric - fluid control, and pneumatic electric hydraulic integrated control. The experimental device uses double-sided structure, ie an experimental table provides places for doing pneumatic and hydraulic test experiment for two groups of four students. The basic configuration is as following: 1 set of pneumatic training components; 1 set of pneumatic PLC control module; 1 piece of low noise air compressor; 1 set of hydraulic training components; 1 set of hydraulic PLC control module; 1 piece of hydraulic test pump. The optional configuration is the computer. It can simultaneously do double-sided comprehensive pneumatic and hydraulic experiments, optimizing and sharing resources and improving products performance. Its overall structure is simple and practical. The training equipment is iron double matte dense spray pattern, which is beautiful, durable and practical.

Integration skills across multiple stations as well as skills specific to an individual station are covered in the balance. Overall system skills include discrete I/O handshaking, system start-up/halt, system stop reset, and FMS programming. The Programming For Educational Training boasts a robust 10 Learning Activity Packets (LAPs). Stations can be easily moved apart to function as individual workstations by releasing two quick connects and one plug-in cable. Stations can also be mixed and matched, enabling instructors to build and change the system as budgets allow or needs change. All mechatronics stations teach operation, sequencing and programming skills. Many mechatronics station combinations are available to support your needs. The first two LAPs concentrate on skills core to all stations: an introduction to mechatronics design, systems concepts, safety, machine operation, sensors, pneumatic pick & place, and electrical pick & place. The Programming For Educational Training includes the Allen-Bradley Programmable Controller, a PLC Portable Mounting Console, 24 VDC Power Supply, Master Control Relay, a Student Learning Activity Packet Set, a Teachers Assessment Guide and an Installation Guide.

Continuous and Indeterminate Beams Apparatus a fourth pier clamps a cantilever or the fixed end of a beam. A double pulley assembly provides vertical loading of the beam. Each pier caters for simply supported, or Continuous and Indeterminate Beams Apparatus and their beam attachments allow for rotation but no vertical movement during testing. Point loads and uniformly distributed loads can be applied to the beams using the set of calibrated weights and hangers supplied. Sinking supports can be studied due to the fact that each reaction pier has a height adjustment system and integral dial gauge attached. Three piers measure vertical reaction forces with their integral load cell which connect directly to the Interface.

The main feature of the machine is that the cradle, in which the rotor to be balanced is supported, has only one degree of freedom which is that of rotation in a horizontal plane about the axis of the crossed spring pivot. The Static and Dynamic Balancing Machine has been developed to provide means for accurate experimental work in the balancing of rigid rotors. The position of the rotor in the cradle is adjusted so that one of the correction planes contains the axis of the cradle suspension and the rotor is balanced for moments about this correction plane by adjustments in the other correction plane. The design of the machine adheres to industrial practice and the machine may be used to balance real rotors of up to 152 mm (6") diameter and 450 mm length in addition to the fivedisc rotor provided. In either case the rotor is then completely balanced, both statically and dynamically. The rotor is then turned round in the cradle and balanced for moments about the other correction plane, or alternatively it is balanced statically.
Experimental Capability:
Four vector method of balancing, two- or three- vector method
Static balancing
Nodal point balancing
Pivot cradle balancing
