CONTRACTORSHANGHAI ELECTRIC GROUP CO. LTDPT. MAXIMA INFRASTRUKTURGear Oil Pump Production Instruction 齿轮油泵产品说明书四川高精净化设备有限公司SICHUAN FINE PURIFICATION EQUIPMENT CORP.LTD1．RIEF INTRODUCTIONWith history of more than 20 years in producing large separation equipment, our compary manufactures Model ZJA High Vacuum Oil Purifier, ZLY Vacuum Oil Filter, JYG Fine Filter,BMS, BAS Manual/Automatic Board Frame Press Oil Filter Which are designed for filtering turbine oil, transformer oil, aviation hydraulic oil, machine oils and Diesel fuel. Besides, We produce WCB，KCB，2CY Geared Oil Delivery Pumps suitable for delivering various medium oils.Model WCB, KCB,2CY Gear Oil Pumps are suitable for fertilizer factory, oil refinery, oil-pressing factory, power plant, transformer station, lubrication oil storehouse, capacitor plant, painting factory and grain departments for delivering oils, such as turbine oil ,transformer oil, aviation oil, mechanical oil, diesel oil and edible oil.WCB,KCB Geared Oil Pump features of good appearance, compact construction, stable performance, low pulsation impact value and low noise less than the specified of the national standard, safety and reliability as well as easy maintenance and service. We provide our customers with wear parts for a long term.Series of gear oil pumps produced by our company find their wide use in national defense, scientific research, Petroleum, light/chemical industry, metallurgy, textile, transportation, Pharmaceutical-making and food departments for delivering non-corrosion heavy oil, mid-viscosity oil, light oil, edible oil and other similes with viscosity below Engler 10°E at temperature below 60℃.However, they are not suitable for delivering dirty oils, lubricating/corrosive medium. Explosion-proof motors and special motors can be provided according to user's requirements.Model WCB Geared oil pump is of one with excellent performance and reasonable price. It can be used in grain sales department for delivering edible oil with illumination power.2.SPECIFICATION3. CONSTRUCTION AND OPERATION PRINCIPLE3.1StructureGeared pump is composed of body ,front/back end cover, driving gear, driven gear, bearings, bearing cap, oilseal coupling, motor, chassis, inlet/oulet oil pipe, flange and safety valve etc.Front/back end cover supports driving/driven gear by means of bearings. The body enables driving gear and driven gear to rotate, resulting in vacuum operation mode. Oilseal acts as sealing of driving shaft. Motor drives driving gear through coupling and shaft pin.2.Moving Sketch3.2 Operation PrincipleWhen driving shaft drives Gear1and Gear2 to rotate in direction shown by arrow and geared teeth disengage gradually in oil suction cavity, teeth disengage from teeth of another gear so that vacuum is formed. aˊ,bˊ…of a, b…between teeth carries oil from oil suction cavity to oil discharge cavity. Oil in geared space is pressed out when gear rotates continuously. Outer load action causes oil pressure. With continuous running of gear, oil pump sucks and discharges oil continuously.When resistance of oil circuit exceed safety Pressure, safety valve starts to make oil in discharge cavity go back suction cavity. In doing so, pressure is reduced and pump/piping is protected.4.INSTALATION AND CONISSIONINGGeared pump and motor is fixed on chassis. Shaft line between motor and geared pump has been adjusted. Geared pump rotates smoothly.During operation, keep an eye to suction height. Rated lift can be obtained. Specified oil inlet/outlet pipes should be chosen. Oil inlet should be through. Before starting, check to see whether fasteners are loose and whether geared pump moves freely. Idle running can't last more than 1 minute. If no oil is sucked in, check geared pump for correct rotation(Running in direction shown by arrow).Check to see whether oil suction pipe joint is loose, connections are leaky and oil groove bottom is blocked by oil suction pipe inserted as well as oil suction height and oil outlet height exceeds tolerance.No abnormal noise and vibration should occur when geared pump works.Safety valve was set in specified safe pressure scope at factory. Users can regulate it. But max regulation puessure can't exceed 40%.5.OPERATION5.1 Before operation, check to see whether geared pump moves freely(Turn by hand).5.2 Make sure power supply is OK and rotation direction of motor is correct.5.3 Check to see whether oil inlet/outlet diameter meets requirements and lift is within specified range.5.4Make sure that all fasteners are firm (Including connectors of inlet/outlet pipe)5.5Before starting, insert oil inlet pipe into oil groove properly. Oil pipe can't reach to groovebottom to prevent blocking intake.5.6Only everything is OK, you may start machine.6.MAINTENANCE AND SAFETY6.1 Connect grounding device6.2 Always keep an eye to loosening of fasteners and abnormal noise of geared pump.6.3 Corse filter should be mounted at oil inlet to prevent iron and impurities from entering pump. 6.4 Oil seal is wear part. In case that driving shaft leaks oil, change oil seal.6.5 Oil pump adopts ball bearings. If ball bearings are worn out, serious noise will occur. Replacement should be made.6.6 After service is completed, made sure that axial gap of the pump, and concentricity should be within tolerance. Otherwise, Pump will fail to work properly.6.7 Geared pump is not allowed to operate in environment and the open-air with high temperature.7.TROUBLESHOOTING AND REMEDYMAIN PARTS AND MATERIALS TABLEBEARING CATALOGUESPARE PART AND WEAR PART CATALGUESPARE PART AND WEAR PART CATALGUEOVERALL AND INSTALLATION DIMEMSIONS OF OIL PUMP一、简介我厂已有二十多年制造分离大型机械设备的历史，产品为各发电厂或从事电力事业的单位提供ZJA系列高真空净油机、ZLY系列真空滤油机、JYG系列精密过滤机、BMS、BAS系列手动和自动板框压滤机、LY系列板框滤油机过滤透平油、变压器油、航空液压油、机油、柴油，还为客户提供WCB、KCB、2CY系列齿轮输油泵，输送各类不同用途的介质油液。
