A.3.5 Dipstick and guide The dipstick guide is of a rigid construction mounted at the centre of the tank. It is constructed to maintain the dipstick in a vertical position, to prevent the scraping of material from the dipstick as it is withdrawn, or the welling of material as the dipstick is being lowered into the tank. The dipstick is constructed in the form of a T-piece which provides the fixed reference point of the dipstick readings. The space between the tip of the dipstick and the bottom of the tank should be at least 50 mm. Figure 6: T-section of dipstick Figure 7: Typical dipstick marking 14
A.4 Pump The pump of a binder distributor is a positive displacement gear pump which means that the quantity of binder that is delivered is directly proportional to the speed of the pump. The pump is normally driven by means of an independent engine, but some newer models are driven by the power take off (PTO) from the gearbox of the vehicle. On some distributors pressure is governed by variable pump speed and on others by constant pump speed and a pressure relief valve. When a pressure relief valve is used, the pump runs at a constant speed and the pressure is automatically maintained in the spray-bar. The manufacturer supplies charts for determining the discharge in litre per minute for each size nozzle as well as the required truck speeds for various application rates and the corrections for temperature-viscosity variations.
