Racor: Морские фильтрационные системы и решения

28 1 Total Air Intake Solutions Clean Up Engine Rooms and Engines Marine diesel engines can benefit from the installation of a combination Racor Closed Crankcase Ventilation (CCV) and Air Filter/Silencer System. The CCV contains Racor’s high-performance Vaporbloc ™ filter made of depth-loading, micro-glass fiber coalescing media. The marine Air Filter/ Silencer (AF) contains a washable media and is ruggedly built to provide an extended service life. The Racor Marine Air Filter/ Silencer removes contaminants introduced into the air from both outside and inside the vessel. Sand, salt, carpet fibers, and other contaminants are trapped in the oil-impregnated Vaporbloc ™ filter media. Turbo noise is reduced by the unique design of the housing. An integral hose connection on the housing routes the clean blowby from the CCV back into the engine. • Pop-up style indicator alerts the operator of a bypass condition and the need for a CCV Vaporbloc ™ filter change. • Air Filter/Silencer is standard with an integral vent port for CCV connection. • Air filter media is washable. • Optional tap sleeves for easy connection of existing air cleaner to CCV assembly. • Prevents turbo and intercooler fouling. Air Filter/Silencers How the Systems Work The engine crankcase breather is connected to the inlet of the Racor CCV assembly. The CCV outlet is connected to the engine’s combustion air inlet via an air intake connector where filtered blowby gas is recycled through the combustion process. Oil collected in the CCV sump is returned to the crankcase through a hose and a drain check valve. Marine Engine Application Worksheet In order to determine the correct Racor CCV system for a particular application, certain engine information is required. A complete kit is composed of the following: 1. Racor CCV assembly 2. Fitting/Hose Kit 3. Air Intake Connector (Tap Sleeve or Marine Air Filter/Silencer Assembly) Select the Racor CCV Assembly: Racor CCV application is determined by crankcase flow in cubic feet per minute or CFM. Flow on new engines is low but as the engine wears on, the CFM increases. Select the correct Racor CCV model by dividing the engine horsepower output by 40. For example: CAT 3116/260HP ÷ 40 = 6.5 CFM, select CCV4500 or CAT 3406/525HP ÷ 40 = 13.13 CFM, select CCV6000 CCV units are designed to handle crankcase flow rates of up to 50 CFM (1416 l/m). Traditionally, the crankcase flow rate can be calculated as follows: Rated horsepower ÷ 40 = cubic feet per minute (CFM). This formula can only be used as a guide since recent improvements in piston design have produced engines with higher horsepower and lower blowby flow rates. The blowby flow rate of a worn engine, at time of overhaul, is generally double the flow rate when the engine is new. The flow rate of a worn engine is factored into the formula. Note : Specify left or right-hand inlet when ordering. Maximum Flow Rate CCV Model Flow CCV4500 10 cfm (283 l/m) CCV6000 20 cfm (566 l/m) CCV8000 40 cfm (1133 l/m) CCV12000 50 CFM (1416 l/m)
