The programme of exercises enables familiarisation with six different drive implementation and analysis methods: understanding the brief and the drawing, assembly, setting, adjusting, testing, and making calculations. This laboratory system is used to introduce combined drives and their correct assembly. The flexibility of the set-up and the modularity of the components simplifies experimentation and implementation of the students' own ideas. All the system components are kept ready to hand and well protected in a housing system. A robust tubular steel frame with a square profile and bearing elements provide the accuracy for the setting of precise gearing.

The unit consists of a pump, a storage tank and a water proof panel on which all friction loss components are arranged. The loss is measured by differential pressure using manometers. Pressure tapping is by valves with quick connection. Piping Loss Test Set Small is a self contained unit for studying the friction loss in pipes, pipe fittings and valves at various flow rates. The unit is on a steel frame on wheels. All pressure taps are connected by flexible hoses to a set of specially arranged manifolds such that differential pressure across any component can be measured simply by opening valves without removing the hoses.
Experiments:
Friction losses in pipe fittings, valves, sudden expansion and contraction at various flow rates.
Friction losses in straight pipes at various flow rates.
The is available in two basic configurations. The standard is the simplest system. As standard the filtration assembly works with polymer membrane filters (90mm diameter) and sample filters are included for microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO). A backpressure valve is used to adjust the transmembrane pressure with a maximum allowable system pressure of 40 bar (analogue pressure indicator). A wider range of filters are available on request. It uses a high pressure stainless steel piston pump to circulate product from a food vessel to the filtration assembly with simple on/off control.
The 50 is an enhanced unit, with all the additional benefits of computer control, data logging and diafiltration capability. There is also an electronic mass balance to measure the mass of permeate collected. This option also enables diafiltration using a peristaltic pump and high level sensor. It includes an electronic pressure sensor to measure filtration pressure (0-40 bar) and electronic temperature sensor (thermocouple) to measure retentate temperature. It also includes a feed pump speed controller, which enables the retentate cross flow velocity over the filtration membrane to be varied. The data from all these is logged in the software enabling plotting of permeate flow rate with time so that the effect of variables (filtration pressure, cross flow velocity, product temperature and diafiltration) on process performance can be determined. The software can be used to define the mass of permeate collected prior to addition of water/buffer (batch diafiltration). Communication to the PC (not supplied) is via an internal USB interface.
Features:
Suitable for microfiltration, ultrafiltration, nanofiltration and reverse osmosis membranes and pressures. Pressure operating range of 1-40 bar.
