Towed wheel-mounted power sprayer 5 Principle of Operation Before starting the pump, the intake hose shall be dipped into the tank filled with the solution. The pressure relief valve shall be opened and shall be set to the desired pressure. The cut-off valve shall be opened and shall be adjusted to achieve the desired spray. The nozzle shall be preset to stream or mist prior to application. Streams shall be directed above the tree while mists shall be directed on the leaves or flowers of the tree. After spraying, the cut-off and pressure relief valves shall be closed before turning off the pump. 6 PAES 157:2011 6 Manufacturing Requirements Generally, the power sprayer shall consist of main frame, prime mover (engine or electric motor), pump, spray hose, lance and nozzle. All specifications indicated below are minimum requirements. 6.1.1 The main frame shall be made of mild steel (e.g. AISI 1020) or better material with a thickness of at least 6 mm. It shall be constructed from welded angular or flat bars. 6.1.2 The prime mover shall be mounted on the main frame with hexagonal bolts with at least 10 mm (3/8") diameter. Lock nuts shall be used to secure the prime mover to the frame. 6.1.3 The pump shall be mounted on the main frame with hexagonal bolts with at least 10 mm (3/8") diameter. Lock nuts shall be used. 6.1.4 The pump shall be of a positive displacement type and shall have a return line integrated in the system. 6.1.5 The spray hose shall be made of chemical resistant polyvinylchloride or better material with an inside diameter of at least 10 mm (3/8"). It shall have a minimum length of 15 m and a maximum length of 200 m. 6.1.6 The lance shall be made of non-corrosive steel or better material. It shall have a length of at least 1 m. 6.1. 7 The nozzle shall be made of non-corrosive material and shall be detachable from the lance to allow replacement. 6.1.8 The nozzle shall be adjustable to produce mist or stream. 6.1.9 Pressure relief valves shall be installed to regulate pressure of the pump. 6.1.10 Cut-off valve shall be installed on the handle of the lance to allow instant stopping of the spray. 6.1.11 Pressure gauge shall have an accuracy of ± 1% of maximum pressure. 6.1.12 Hose clamps shall be made of non-corrosive material. 6.1.13 Frame handle shall be covered with a non-slip and non-corrosive Inaterial. 6.1.14 The power sprayer shall have a minimum of two filters, which are made of non-corrosive material, with each allowing easy cleaning, maintenance and/or replacement 6.1.15 The filter shall have a mesh of 100 per square centimeter. 7 PAES 157:2011 6.1.16 All welded parts shall be in accordance with the criteria set in A WS D1.1:2000. 6.1.16.1 There shall be no crack on welded area. 6.1.16.2 There shall be fusion between adjacent layers of weld metal and base metal. 6.1.16.3 All craters shall be filled to provide the specified weld size, except for the end of intermittent fillet welds outside of their effective length. 6.1.16.4 Welded joints shall not be less than 4 mm size fillet weld. 6.1.16.5 Undercut shall not exceed 2 mm for any length of weld. 6.1.17 Frame mounted power sprayer 6.1.17.1 The intake hose shall be made of chemical resistant polyvinylchloride or better material with an inside diameter of at least 16 mm.
