IntroductionThe mobile engine compressor washing rig (JMP/T800/D/4796) consists of two stainless steel pressuretanks, each having a capacity of 34 litres (9 US gal) mounted in tandem on a transportation trolley, togetherwith a nitrogen cylinder. Each of the stainless steel pressure tanks is equipped with a sight glass indicatingthe level of fluid, a filler cap, gauze strainer, pressure relief valve, nitrogen inlet valve, fluid outlet valve anddrain valve.The rig comprises a welded, tubular steel frame, which forms a transportation trolley for the two pressuretanks and a single nitrogen cylinder. Two wheels, with urethane filled tyres, run on a solid axle which isbolted to the frame. At the front, two rubber feet support the trolley.OperationThe fluid in each of the pressure tanks is pressurised by nitrogen, which is contained in a cylindermounted in the upright position at the front of the rig. The nitrogen supply to the pressure tanks iscontrolled by a pressure regulator, the pressure in the tanks being indicated by pressure gauges locatedon each of the tanks. The reduced nitrogen pressure from the pressure regulator is distributed to thetop of the rinse and wash solution pressure tanks via an air inlet manifold. A non-return valve, fitted priorto the inlet valve on each tank, prevents fluid entering the pressure supply lines should the rig be tiltedrearwards during operation.When the tanks are pressurized, fluid is forced up an outlet stack pipe to an outlet ball valve. During pressurization and during the washing process, the nitrogen bubbles through the fluid creating agitation. Thisis particularly useful if the solution being used requires extra mixing. A 4.57m (15 ft) long, 1⁄2 in. nominalbore fluid delivery hose terminates in a 1⁄2 in x 9⁄16 in. swivel hose end union. A protective collar is fitted tothe end of the delivery hose. The delivery hose is stowed around brackets mounted on the right handside of the frame.DevelopmentSize: (L) 1245mm x (W) 610mm x (H) 1118mm Weight: (Dry) 100KgAccessories: Contact us or refer to our website for a full list of lances.This rig was originally produced for use withthe Westland Super Lynx helicopter.DETAILSRig VariationsJMP/T800/D/4796 ( First appeared - 2004)The standard version of the rig.
