Marine 2hm Series Main Engine Lube Oil Pump for Tanker Vessel
Warranty: 1 Year
Screw Number: Double Screw Pump
Screw Suction Method: Double Suction
Pump Shaft Position: Horizontal
Performance: No Leak
China Huanggong Machinery Group Co.,Ltd.---------Specialist in marine pump industry for over 40 years.Main featrues of 2W series twin screw pumpA. Deliver various medium smoothly without disturbing and pulsation. There are medium to be pumped throughout in the working elements as sealing liquid which guaranteed by the construction of pump casing, so all of the pump possess high self priming ability and can deliver the liquid mixtured with gas or air.B. The high suction perpormance(low NPSHr) was guaranteed by the special design of pump.C. Independent lubricating external bearing allows various non-lubrication medium to be delivered.D. As we adopted synchrinous gear to make sure no metallic contact between rotating parts, there is no dangerous even dry running in a short time(1~2min).E. Various construction such as horizontal, vertical and casing with heating jacket, and so on. The pump can deliver various clean liquid without solid grain, low or high viscosity medium, and even some corrosive medium when correct materials are selected.F. Suction of the pump is on the side and discharge is on the top, the pump has small cub-age, so it is especially suitable for the place of small space, such as ship.Specification of our twin screw pump:A. Using rangeTwin-screw pump can transfer various non-solid contained fluid medium or extremely high viscosity medium. They have wide availability and high reliability for lubricating or non lubricating medium, for corrosive medium or gas-liquid mixture.Capacity: 0.5-1500m3/hPressure: 0.1-2.0MpaViscosity: 0.5-100, 00mm2/sTemperature: -30 - 200 CMedium: Various lubricating oil and fuel oilB. Using field1. Petrochemical Industry: Transfer pump for various lubricating oil, crude oil, residual oil, heavy oil, bitumen, diesel oil, gasoline etc.2. Shipbuilding Industry: Transfer pump, cargo oil pump, booster pump, striping pump and engine lubricating pump for various fuel oil, lubricating oil, waste oil, bilge sludge and sea water etc.3 Chemical Industry: Transfer pump for various acid, alkali and salt solution, resin, glycerin, olefin, polymers and various cosmetics emulsion.4. Paint Industry: Transfer Pump for various printing ink, paint, oil paint, dope etc.5. Food Industry: Transfer pump for various high-viscosity medium like alcohol, beverage, honey, sugar juice, tooth paste, milk, soy sauce, animal oil, vegetable and chocolate etc.6. Saving & Transferring industry: Loading and unloading oil goods for oil station, ship and tanker.C. Features1, The inlet-outlet civility adopts special design to make sure that enough medium is remained in the pump. Even when the medium in the suction pipe is all discharged, the pump still has very good self-suction performance.2, The pump body adopts special-structure circular valve, which will open when the outlet pressure is higher than the working pressure. Then, some medium will back to the inlet of pump or saving can through this circular valve. Meanwhile, the pump can starts under full pressure situation thus greatly reduce the torque.3, Use synchronizer gear to transfer toque from initiative screw to idler screw, which ensures no metal contact and power transmission between transferring elements. So the transferring elements have high reliability for any medium and the pump can free from damage of dry rotation in a short time.4, When the pump is working, the meshing screws form a sealed civility in the pump body, following the rotary motion of the screws, the liquid in the sealed civility does axial motion with the sealed civility and transferred to the outlet of pump steadily and continuously. Because the capacity of the sealed civility never changes in the working pump, there will be no pulsation when the pump deliveries liquid.5, The body of twin screw pump has several different heating structure plans for choice, to adapt to different medium under different temperature.2WSeries:2W2-12,2W2-18,2W2-24,2W2-36,2W2-482W3-20,2W3-28,2W3-40,2W3-562W4-25,2W4-34,2W4-50,2W4-722W5-30,2W5-40,2W5-60,2W5-802W6-38,2W6-50,2W6-75,2W6-962W7-43,2W7-56,2W7-85,2W7-1122W8-50,2W8-67,2W8-100,2W8-1282W9-80,2W9-100,2W9-128,2W9-1502W10-80,2W10-100,2W10-128,2W10-1502W11-128,2W11-160,2W11-176,2W11-192,2W11-2502HM Series2HM280-20,2HM280-28,2HM280-40,2HM280-562HM560-25,2HM560-34,2HM560-50,2HM560-722HM800-30,2HM800-40,2HM800-60,2HM800-802HM1400-38,2HM1400-50,2HM1400-75,2HM1400-962HM2500-43,2HM2500-56,2HM2500-85,2HM2500-1122HM4200-50,2HM4200-67,2HM4200-100,2HM4200-1282HM7000-80,2HM7000-100,2HM7000-128,2HM7000-1502HM9800-80,2HM9800-100,2HM9800-128,2HM9800-1502HM9800-144,2HM9800-1602HM18000-176,2HM18000-192,2HM18000-250How to disassemble and maintenance twin screw pumpRemove the coupling and take out the flat key;Take down the shaft covers of both ends, bearing pressed nut and check out the gasket.Remove nuts on the shaft and a positioning, then exit shaft bracket with screw.Take down the shaft bearings.Remove the block and oil seal gland and take out the the oil seal gland.Check and replace the damaged parts in time.
