8、該系列渣漿泵產(chǎn)品具有結(jié)構(gòu)合理、效率高、運(yùn)行可靠和維修方便等優(yōu)點(diǎn)，廣泛適用于電力、冶金、礦金、煤炭、建材、化工等工業(yè)部門輸出送腐蝕性渣漿，特別是電廠灰渣。

英國(guó)GRIMM格林進(jìn)口渣漿泵密封形式：
進(jìn)口渣漿泵可以采用副葉輪加填料組合式密封和機(jī)械密封兩種軸封形式。
⑴副葉輪動(dòng)力密封加填料密封：副葉輪密封利用葉輪與串聯(lián)的副葉輪產(chǎn)生的壓力密封，填料或唇口密封圈作為停車密封。在泵進(jìn)口壓力值不大于泵出口壓力值10%時(shí)的單級(jí)泵或多級(jí)泵串聯(lián)的第一級(jí)泵，可以采用這種密封形式。它可以在沒(méi)有軸封水的情況下運(yùn)行，不稀釋礦漿、密封效果好等特點(diǎn)。但將增加功率消耗(一般需增加軸功率的5%左右)。填料密封是常見(jiàn)的一種軸封形式，適用于各種工況條件，可匹配聚四氟乙烯填料、石墨填料等特殊材質(zhì)，可用于腐蝕性或高溫條件下。具有結(jié)構(gòu)簡(jiǎn)單、維修方便等優(yōu)點(diǎn)。
⑵機(jī)械密封：采用國(guó)際lingxian的密封技術(shù)，密封效果好。集裝式結(jié)構(gòu)使安裝與更換更方便，不同的結(jié)構(gòu)形式適應(yīng)不同的工況條件。磨擦副材料采用高硬度陶瓷及合金材料，機(jī)械密封和密封箱設(shè)計(jì)與配合符合介質(zhì)流動(dòng)狀態(tài)，因而具有較高的抗磨性和抗震性，在各種惡劣的工況下均能保證客戶滿意。

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.
