13 OPERATING PRINCIPLES 3. OPERATING PRINCIPLES DYNASET HRU Hydraulic rescue unit is based on HPW pump with modifications to withstand extreme pressure. The HPW pump inside the HRU unit creates the needed pressure. 1. The HRU unit is operatable when the hydraulic flow is opened to the HRU unit. after this the hydraulic flow will travel through the pump which pressurizes the pumping fluid. 2. The pressurized pumping fluid is then directed through On/Off operating block. When the operating block is closed the flow will travel through bypass valve to the tank. The patented HPW-pump utilizes the reciprocal motion of the hydraulic piston. 2 1 Picture 4: HRU Operating principle Dynaset Oy Menotie 3, Ylöjärvi puh info@dynaset.com 13

14 OPERATING PRINCIPLES Picture 5: Operating description of HPW pump 1 HPW-pump is driven by hyraulic flow through the hydraulic ports (P) and (T). Hydraulic flow moves the piston assembly (1) into its extreme position. After exteme position reached, reversal valve (2) inside the piston assembly changes the direction of hydraulic flow and the piston assembly starts to move into the opposite direction. Picture 6: Operating description of HPW pump 2 14 Dynaset Oy Menotie 3, Ylöjärvi puh info@dynaset.com

15 OPERATING PRINCIPLES Move of the piston assembly creates pressure and suction. Pump self-primes from supply line (S) and generates pressure into pressure line (WP). When piston assembly moves away from head it creates underpressure (3) and water (or other pumping fluid) is sucked through intake valve (4) into head. When piston moves towards the head, it creates pressure (5) and water is pushed through pressure valve (6) into pumping fluid outlet (WP). The relation ship between hydraulic oil flow and pressure to pumping fluid flow and pressure is linear.

17 INSTALLATION 4. INSTALLATION 4.1. BEFORE INSTALLATION ATTENTION! Read the instructions before installing the DYNASET product! 4.2. INSTALLATION TO A HYDRAULIC TOOL LINE HRU is recommended to be installed into the base machine s existing hydraulic tool line. Usually other installations are not required and the HRU can be operated from the existing controls. Install the hydraulic tool lines pressure (P) and return (T) to their correct places on the HRU. Ensure that the hydraulic flow of the base machine is sufficient to run the unit. At least the minimal flow must be available. READ CHAPTER 10. TECHNICAL SPECIFICATIONS.

23 OPERATING INSTRUCTIONS 5. OPERATION 5.1. STARTING THE HPW PUMP ATTENTION! Check all hoses and couplings in hydraulic and pumping fluid circuits before use to ensure there are no leaks or damages. Ensure that there is pumping fluid available in the HRU tank. 1. When the engine of base machine is running and hydraulic flow is available, the HRU can be started by opening the hydraulic control valve. 2. After strating the HRU the pressurised pumping fluid flow can be directed to the wanted tool or appliance by opening the operating block. When the operating valve is off position the the flow will travel through the bypass valve to the tank. 2 1 Picture 13: Starting the HRU unit 5.2. PUMPING FLUIDS Most liquids, which can be transferred by pumping, can be used with HRU. Solvents and oils can be pumped without any special arrangements. When HPW pump is going to be used as a self-priming unit with a special or high viscosity liquid, the flow and self-priming conditions should be valuated. If the self-priming property can not be reached, pumping liquid is to be fed with certain pressure, or the pump should be used at lower hydraulic flow. READ CHAPTER 10. TECHNICAL SPECIFICATIONS for specific values of your HPW pump. Dynaset Oy Menotie 3, Ylöjärvi puh info@dynaset.com 23

24 OPERATING INSTRUCTIONS NOTE! HPW pump can be run dry unlimited time without any harm, because selflubricating sealing and circulating hydraulic oil prevent the pump from overheating STOPPING THE HPW PUMP HRU is stopped by shutting off the hydraulic flow.
