英国GRIMM格林进口自吸式离心油泵 UK GRIMM Imported self-priming centrifugal oil pump

英国GRIMM格林进口自吸式离心油泵概述： 

          进口自吸式离心油泵是根据英国格林有关技术资料经消化、吸收、改进后研制而成的zui新泵类产品，该阀适用于油库、加油站、游船、码头、油罐车、机场，分别输送汽油、煤油、柴油、航煤等，如改用耐腐蚀机械密封和不锈钢材质还可以适用于化工、制药、酿造、电镀、印染、电力矿山等，输送介质温度-20℃～80℃，粘度≤100厘珀、含固量可达30%以下。

英国GRIMM格林进口自吸式离心油泵特点：

1、该泵属于自吸式离心泵，它具有结构简单、操作方便、运行平稳、维护容易、效率高、寿命长，具有较强的自吸能力能等特点。管路中不需底阀，工作前只需保证泵体内储有定量引油即可。用于油轮或输水船舶上时，可兼作扫舱泵，扫舱效果良好。
2、该泵是选用优质材料精作而成，密封采用硬质合金机械密封，经久耐用，吐出管路不需要安装安全阀，吸入管路不需要安装底阀因此简化了管路系统，又改善了劳动条件。

英国GRIMM格林进口自吸式离心油泵结构说明及工作原理： 

             该泵均采用轴向回液的泵体结构。泵体由吸入室、储液室、涡卷室、回液孔、气液分离室等组成，泵正常起动后，叶轮将吸入室所存的液体及吸入管路中的空气一起吸入，并在叶轮内得以完全混合，在离心力的作用下，液体夹带着气体向涡卷室外缘流动，在叶轮的外缘上形成有一定厚度的白色泡沫带及高速旋转液环。气液混合体通过扩散管进入气液分离室。此时，由于流速突然降低，较轻的气体从混合气液中被分离出来，气体通过泵体吐出口继续上升排出。脱气后的液体回到储液室，并由回流孔再次进入叶轮，与叶轮内部从吸入管路中吸入的气体再次混合，在高速旋转的叶轮作用下，又流向叶轮外缘▪▪▪▪▪▪。随着这个过程周而复始的进行下去，吸入管路中的空气不断减少，直到吸尽气体，完成自吸过程，泵便投入正常作业。因为该泵具有这种独特的排气能力，所以此泵能输送含有气体的液体，无需安装底阀，使用在油轮上时具有良好的扫舱功能。
          在一些泵的轴承体底部还设有冷却室。当轴承发热引起轴承体温升超过70度时，可在冷却室处通过任意一只冷却液管接头，注人冷却液循环冷却。泵内部防止液体 由高压区向低压区泄漏的密封机构是前后密封环，前密封环装在泵体上，后密封环装在轴承体上，当泵经长期运转密封环磨损到一定程度，并影响到水泵的效率及自 吸性能,应给予更换。

UK GRIMM Imported self-priming centrifugal oil pump summary:

         The import of self-priming centrifugal pump is based on the relevant technical data in Britain by Green digestion and absorption and improvement of a new pump products, the valve is suitable for oil depot, gas station, oil tanker, cruise ships, docks, airports, transport gasoline, kerosene and diesel respectively, aviation kerosene, such as corrosion resistance to mechanical seal and the stainless steel material also can be used in chemical, pharmaceutical, brewing, printing and dyeing, electroplating, mining and other power transmission medium, the temperature of -20 to 80 DEG C, the viscosity is less than or equal to 100 per cent, Perot solid content is below 30%.

UK GRIMM Imported self-priming centrifugal oil pump characteristic:

1. The pump belongs to self suction centrifugal pump. It has the characteristics of simple structure, easy operation, stable running, easy maintenance, high efficiency, long service life, strong self suction ability and so on. At the end of the valve is not needed in the pipeline, just before work to ensure the pump body certain priming oil. The utility model can be used as a scavenging pump for an oil tanker or a water delivery ship, and the scavenging effect is good.

2. The pump is made of high quality material and fine, with hard alloy mechanical seal, durable, spit pipe does not need to install the safety valve, the suction pipe does not need to install the valve thus simplifying the piping system, and improved working conditions.

UK GRIMM Imported self-priming centrifugal oil pump structure deion and working principle:

           The pump adopts axial return liquid pump structure. The pump body is composed of a suction chamber, a liquid storage chamber, swirl chamber, liquid return hole, etc. the gas-liquid separation chamber, pump normal starting, impeller suction chamber of the liquid suction pipe and the air suction, and can be fully mixed in the impeller under the action of centrifugal force, the liquid with gas to the edge of the swirl chamber flow, the formation of a certain thickness of white foam and high-speed liquid ring on the outer edge of the impeller. The gas-liquid mixture passes through the diffusion tube into the gas-liquid separation chamber. At this point, as the flow rate suddenly decreases, the lighter gas is separated from the mixture gas, and the gas continues to rise and discharge through the pump body. After the degassing of liquid to the liquid storage chamber, and the reflux hole again into the gas and the impeller, impeller sucked from the suction pipe again mixed in high speed rotating impeller role, and flows to the outer edge of the impeller feels feels feels feels feels feels. As the process goes on and on, the air in the suction line continues to decrease until the gas is exhausted and the self-priming process is completed, and the pump is put into normal operation. Because the pump has the unique exhaust ability, so the pump can transport the liquid containing a gas, no need to install the valve, use the tanker good stripping function.

         A cooling chamber is also arranged at the bottom of the bearing body of some pumps. When the bearing heats up and causes the bearing temperature to rise by more than 70 degrees, it can be recirculated and cooled by any coolant pipe joint in the cooling room. Internal prevent liquid pump seal by high pressure leakage from the low pressure area is around the ring, in the pump body before and after sealing ring, sealing ring installed in the bearing body, when the pump running through long-term ring wear to a certain degree, and affect the efficiency of the pump and self-priming performance, should give change.
