英国GRIMM格林进口离心油泵 UK GRIMM imported centrifugal oil pump
UK GRIMM imported centrifugal oil pump summary:
The import of the centrifugal pump, based on a British Green old type oil pump series and re design, it is to meet the needs of modernization, adapt to the new product update to the center for the energy-saving equipment.
UK GRIMM imported centrifugal oil pump characteristic:
1.The bearing body parts will be the original 35, 50 and 60 bearing bodies with 45, 55, 70 bearings, respectively, to improve reliability;
2.The water conservancy part uses the energy saving water conservancy model, the average efficiency is higher than the Y type oil pump efficiency 5 to 8%;
3.In order to ensure the inheritance, the pump structure, shape, installation size and performance range are the same as those of the old type oil pump, so that the old equipment can be renewed and transformed;
4.Material selection, refining, the main theme of the class II, III class materials, bearings and other parts increased to cast steel, cast iron two kinds, for cold areas for outdoor use, ship provides a powerful condition;
5.High degree of commonality of parts and components, standard parts for several series of products common, bearing oil, air cooling, fan cooling, water cooling three cooling methods, according to the temperature of the pump medium selection. Among them, fan cooling is especially suitable for water shortage or poor water quality areas.
UK GRIMM imported centrifugal oil pump structure characteristics:
The inlet centrifugal pump is a radial part of the segmental structure, and the rod is connected with the suction section, the middle section and the spit section. The rotor of the pump consists of impeller, balance disc (drum) installed on the shaft. The axial force is balanced by the balance disc, balance drum and thrust bearing.
Bearings: radial sliding bearings or radial ball bearings. Thrust bearings adopt thrust thrust ball bearings to balance the residual axial forces.
Shaft seal: use packing seal or mechanical seal, according to the user's needs.
Transmission: the pump is driven directly by the prime mover through a flexible diaphragm coupling, and the pump rotates counterclockwise as viewed from the prime mover.
Pipeline system: cooling water is based on the medium temperature and the use of requirements, the shaft seal cavity, bearing or pump support, such as cooling, water quantity of each pipeline is recommended as 0.25-0.5m3/h, the pressure is: 0.25-0.3MPa. Sealing flushing is based on the pump medium, temperature and pressure and other working conditions vary. The pressure of the sealing liquid is generally higher than the pressure of the sealing chamber 0.07-0.1MPa. If the transport medium is easy to vaporize, it should be higher than the vaporization pressure 0.175-0.2MPa. The steam pipe is equipped when the temperature of the conveying medium is reduced and the pressure is about 0.1MPa.
UK GRIMM imported centrifugal oil pump technical parameter:
Flow rate: 6.25-155m3/h
Operating temperature: -20 DEG C to +300 C
Working pressure: 1.6-10.0Mpa
Material: cast iron, cast steel, stainless steel
UK GRIMM imported centrifugal oil pump scope of application:
Mainly used in petroleum refining, petrochemical and chemical industries and other local delivery of solid particles in oil and liquefied petroleum gas medium, the pump shell radial part, especially suitable for high temperature and high pressure and transport of flammable, explosive or toxic liquid.
