WXHZ Oil lubrication devjice is composted by oil unit,instrument board and electrical controller, is a heart of circulatory lubrication system, to force the oil press to the machine friction parts, makes a oil film, to reduce the friction, lower the damage, flush the parts and carry out the heat from friction parts ,to ensure the machine operating ordinary ,prolong the life. This oil device is compact in structure, seizes small area ,convenience in use ,can consist an　independent stand-alone circulatory system, to eleate the auto control ability of full lubrication system. This oil device is compact in structur, seizes small area, convenience in use, can consist an independent stand-alone circulatory system, to elevate the outo control ability of full lubrication system. This device is mounted usually nearby the oil storeroom underground or pits inside. It is applicable to the circularly lubricate system of metallurgy, mine, casting & forging, power, chemistry and light introduce,to oil the friction parts of reducer, gear box and bearings of main machine.

Note：1.This series still contain; WXHZ630、630AI、800、800AI、800A、1000、……2000A etc.
             2.Lubricant oil viscosity among 20-320cSt.
             3.Filter precision of lower viscosity oil is 0.08mm; high viscosity oil is 0.12mm.
             4.Cooling water temperature ≤30℃,pressure ≤0.4MPa; when the temperature of oil entered cooler is 50℃ and oil                                 temperature drops ≥8℃; the steam pressure heated is 0.2～0.4MPa.
             5. WXHZ－160～500 are mounted on a common base all the components except oil tank; WXHZ－160A～500A are         mounted on earth directly all the components. This device prepare with an electrical ecotroller and an instrument board.
