Description

This unit is designed as a portable and self-contained service module for the range of accessories described later in this data sheet.

The bench is constructed from lightweight corrosion resistant plastic and is mounted on wheels for mobility. The bench top incorporates an open channel with side channels to support the accessory on test.

Volumetric measurement is integral and has been chosen in preference to other methods of flow measurement for its ease of use, accuracy and safety in use (no heavy weights for students to drop). The volumetric measuring tank is stepped to accommodate low or high flow rates.

A stilling baffle reduces turbulence and a remote sight tube with scale gives an instantaneous indication of water level. A measuring cylinder is included in the supply for measurement of very small flow rates.

A dump valve in the base of the volumetric tank is operated by a remote actuator. Opening the dump valve returns the measured volume of water to the sump in the base of the bench for recycling. An overflow in the volumetric tank avoids flooding.

Water is drawn from the sump tank by a centrifugal pump and a panel mounted control valve regulates the flow. An easy-to-use quick release pipe connector situated in the bench top allows for the rapid exchange of accessories without the need for hand tools.

Each accessory is supplied as a complete piece of equipment needing no additional service items other than the Hydraulics Bench. When coupled to the bench they are immediately ready for use.
