2. INSTRUCTIONS FOR USE
2.1 Fill the reservoir to be nearly full. Be sure that the tank and the water are clean.
2.2 Close the pump flow control valve.
2.3 Outlet coupling details:
Figure 2-1 Hydraulics Bench outlet. Figure 2-2 Coupling.
2.3.1 The bench outlet is a 1 in. internal thread outlet.
2.3.2 A 1 in. male adapter with 3/4 in.female quick coupling is attached to the bench outlet.
2.3.3 Most Hydraulics Bench test apparatus use 3/4 in. male quick coupling for connecting to the bench for
water supply. Simply press the female coupling down to release the male coupling.
2.4 Place the apparatus on the bench and connect the bench outlet to the test apparatus.
2.5 Start the pump (both ELCB and CB) and slowly open the flow control valve to the required flow rate by
observing the Rotameter (optional) reading.
Note: If an inverter is used, adjust inverter to regulate pump speed, thus flow rate.
2.6 Use of measuring tank is as follows:
2.6.1 When the flow from the test equipment to the measuring tank is steady close the tank drain valve.
The water level will now slowly increase.
2.6.2 Start the stop watch when the water level reaches “0” and stop the watch when the required level is
reached. The upper tank is measured the same way.
2.7 There is a level indicator on the side of the bench to indicate water levels in the channel as well as in the
measuring tank. The level gauge for the bench channel is a special feature provided by HB 100. Thus, a
flow over a notch experiment can be carried out without using the hook and point gauge.
2.8 The reservoir should be drained when the bench is not in use and the pump should also be drained if the bench
is not going to be used for a long time. Leaving water in the pump will induce rust and the pump shaft may
seize. (See also Addendum 1 Water Pump Maintenance)
2.9 After the experiment, turn off both ELCB and CB.
Note: It is recommended to add anti rust liquid to the water to minimize rust in the system.
