-lab-828036244.jpg "Worm and Wheel Apparatus (30 : 1 ratio)")
The Worm and Wheel Apparatus pair has a single start and a ratio of 30:1. The Worm and Wheel Apparatus are positioned a set distance apart to mesh correctly. Both parts run in bearings with the worm operating with an additional thrust bearing. Worm and Wheel Apparatus high quality example of an industry standard worm and wheel pairing is built on a substantial wall mounted bracket for vertical mounting.
Attached to the end of the Worm and Wheel Apparatus is a pulley (EFFORT) of known effective diameter. This pulley is used for the loading of the system. Again a cord is wrapped around its periphery and terminates in a load hanger. This hanger helps exert the loading onto the system via the weights set provided. This pulley helps exert the effort to raise a load. A cord is wrapped around its periphery and terminates in a load hanger for applying effort load. Attached to the front of the wheel is another pulley (LOAD) of known effective diameter.
Experimental Capabilities:
Determination of EFFORT with variation of load
Determination of limiting efficiency of the machine
Determination of friction with variation of load
Experimental determination of velocity ratio and comparison with calculated value
Determination of efficiency with variation of load.
All electrical components are industry standard components and the system circuit diagram is printed on the front panel. Test sockets are inserted to enable measuring instruments to be connected for fault finding. It includes 15 fault insertion switches.
A Domestic Air Conditioning Controls Simulator for studying the function of the electrical components commonly used in ventilation and air conditioning equipment. It also allows students to become familiar with fault finding and diagnosis.
The has been designed and manufactured to incorporate all current safety standards.
The shows the electrical circuit for an air conditioning system. The compressor, fan and heater are automatically simulated in the equipment.
Flow straighteners and guide vanes are used. A choice of between one and three flow pumps can be ordered to provide maximum flow rates between 0.3 and 0.8m/s at maximum operating depths. Higher flow rates can be achieved with a smaller depth of water. 300 x 450 mm flow channel (Advanced flow channels) is designed in a modular way to allow different configurations to be purchased against the current and future needs of the user. The inlet chamber has been designed from experience with cavitation tunnels to provide a relatively stable flow. The basic channel is manufactured in 5m sections such that a length of up to 20m can be purchased. The walls of the channel are made from plexiglass (with toughened glass options), the base of the channel is formed from aluminium (with a stainless steel option), and the frame from a coated mild steel fabrication.
