英国GRIMM格林进口渣浆泵密封形式：
进口渣浆泵可以采用副叶轮加填料组合式密封和机械密封两种轴封形式。
⑴副叶轮动力密封加填料密封：副叶轮密封利用叶轮与串联的副叶轮产生的压力密封，填料或唇口密封圈作为停车密封。在泵进口压力值不大于泵出口压力值10%时的单级泵或多级泵串联的DY级泵，可以采用这种密封形式。它可以在没有轴封水的情况下运行，不稀释矿浆、密封效果好等特点。但将增加功率消耗(一般需增加轴功率的5%左右)。填料密封是常见的一种轴封形式，适用于各种工况条件，可匹配聚四氟乙烯填料、石墨填料等特殊材质，可用于腐蚀性或高温条件下。具有结构简单、维修方便等优点。
⑵机械密封：采用国际**的密封技术，密封效果好。集装式结构使安装与更换更方便，不同的结构形式适应不同的工况条件。磨擦副材料采用高硬度陶瓷及合金材料，机械密封和密封箱设计与配合符合介质流动状态，因而具有较高的抗磨性和抗震性，在各种恶劣的工况下均能保证客户满意。

UK GRIMM imported slurry pump summary:
imported slurry pump is horizontal, single stage, single suction, cantilever, double pump shell, centrifugal slurry pump. In order to meet the needs of the development of mining, electricity, metallurgy, mining and other industries, the dust removal characteristics of slag and slurry transport conditions, after decades of experience in design and manufacture of slurry pump on the basis of absorbing and researching achievements of domestic and foreign advanced technology, the British green company has developed a new generation of slurry pump with large flow and high lift and multi-stage series.
UK GRIMM imported slurry pump main features:
1. The use of modern CAD design method, excellent hydraulic performance, high efficiency and low wear rate; flow spacious, anti clogging performance, cavitation performance;
2. Using impeller instead of filling, combination type seal and mechanical seal, to ensure that the slurry pump without leakage;
3. The reliability design guarantees the machine average trouble free working time (MTBF) greatly improved;
4. The use of thin oil lubrication metric bearings, reasonable lubrication and cooling system, to ensure that bearings in low temperature state;
5. The over-current parts are made of special material with good wear resistance and corrosion resistance;
6. After special treatment, it can be used for seawater ash removal, electrochemical corrosion of sea water and salt fog;
7. In the allowable pressure range can be used in series, which allows the maximum working pressure of 3.6MPa.
8. This series of slurry pump has the advantages of reasonable structure, high efficiency, reliable operation and convenient maintenance, widely used in metallurgy, mine, electric power industry gold, coal, building materials and chemical industry output to corrosive slurry, especially power plant ash.
UK GRIMM imported slurry pump sealed form:
The imported slurry pump can be made of two kinds of shaft seals, such as auxiliary impeller, packing, combination seal and mechanical seal.
The vice impeller dynamic seal and packing seal: vice impeller seal generated by the impeller and the impeller side series pressure seal, filler or lip seal as stop seal. In the pump inlet pressure value is not greater than the pump outlet pressure value of 10% when the single-stage pump or multi-stage pump in series with the first stage pump, you can use this form of seal. The utility model can be operated without the shaft seal water, the slurry is not diluted, and the sealing effect is good. But it will increase power consumption (generally increase about 5% of shaft power). Packing seal is a common form of shaft seal. It is suitable for all kinds of working conditions, and can be matched with PTFE stuffing, graphite filler and other special materials. It can be used in corrosive or high temperature conditions. The utility model has the advantages of simple structure, convenient maintenance and the like.
Mechanical seal: use international advanced sealing technology, good sealing effect. The container type structure makes installation and replacement more convenient, and different structural forms adapt to different working conditions. The friction pair of high hardness ceramic materials and alloy materials, mechanical seal and seal box with the design conforms to the medium flow state, so it has high abrasion resistance and shock resistance, can guarantee the customer satisfaction in a variety of harsh conditions.
