www.lewmar.com Hydraulic Integrated Engineering Systems Four main assemblies need to be carefully considered to enable the system to be correctly specified. ▪ Power pack suitably sized to match hydraulic functions such as winches, windlasses, furlers, cylinder etc. ▪ Directional control valve stations, these can be on one manifold block with one to six valves, or in any combination of manifolds and valves. A range of valve assemblies are available to suit operating requirement of hydraulic functions. ▪ Control System is a bespoke control system with customised operator interface and helm controls, with additional optional extras such as stainless steel mounting panel. ▪ Return line oil filter maintains a good level of oil cleanliness which is essential to the performance and reliability to the hydraulic system. PTO Pump Control The control system can monitor the main engine speed or a generator status to engage a pump on the PTO when power is available and automatically disengage to reduce wear and power wastage. Panels Control panels designed and manufactured in a variety of weather resistant materials and components provide overall system and individual function control, from a helm station or other location as desired. Features multicoloured indicating push buttons and switching or proportional joysticks for control of thrusters, captive winches and sail furling systems. PowerPack When a system has more than one electric motor-pump, the control system will tailor the operation of each motor to start and stop individually or in conjunction in order to meet the hydraulic requirements efficiently and to reduce motor wear and strain on the power supply. All motors are thermally monitored and made safe in case of overheating. Both AC & DC motors can be provided with an option with variable speed control giving soft starting and idle speed control to improve response times, further reducing wear.
