煤泥壓濾機泵@金華煤泥壓濾機泵@煤泥壓濾機泵維護

The first machinery to be applied to chemical dehydration. Although the plate and frame filter press is generally intermittent operation, infrastructure equipment investment is large, filtration capacity is also low, but because of its large filtration driving force, filter cake with high solid rate, b filter, high solid recovery rate, low conditioning consumption and other advantages, in some small sewage plants are still widely used. After the sludge has been condensed and digested, there is still about 95%~97% water content, the volume remains very large. Sludge Dewatering can further remove the voids and capillary water in the sludge and reduce its volume. After dehydration treatment, the water content of sludge can be reduced to 70%~80%, its volume is the original volume of 1/10~1/4, is conducive to subsequent transport and treatment. Sludge mechanical dewatering bs are filtration dehydration, centrifugal dehydration and press dehydration, filtration dehydration and vacuum filtration and pressure filtration, centrifugal dehydration is the use of centrifuges for dehydration, press dehydration is the use of spiral press or rolling machine for dehydration. Commonly used are pressure filtration and centrifugal dehydration bs.

Hydraulic compb is a hydraulic station through the rack of the hydraulic cylinder components to promote the compb plate compression. The two beams connect the thrust plate and the compb device together to b the rack, the press on the rack and the clamping device are connected, and the filter plate and the filter frame are arranged alternaby between the thrust plate and the clamping plate, and the filter medium is clamped between the filter plate and the filter frame, and the compb device pushes the clamping plate, presses all the filter plates and the filter frame in the rack, and after reaching the rated compb force, Can be filtered. Suspension from the feed hole on the thrust plate into the filter chamber (filter frame and adjacent filter plate to b the filter chamber), solid particles are filtered by the filter medium in the filter room, the filter through the medium, from the liquid hole out of the machine. The liquid of the filter press has two bs, the b flow and the undercurrent, filter from each filter plate out of the liquid hole directly discharged from the machine outside the call flow, the b flow type is convenient for each filter plate filtration situation, found that a filter plate filter is not pure, you can close the plate out of the liquid mouth; If the filter of the filters converge from an outlet pipe out of the machine, it is called the undercurrent type.

二、創(chuàng)新技術(shù)特點
1.獨特的密封裝置采用負壓技術(shù)加組合密封裝置，在壓力不斷增加而流量逐漸減少的情況下，密封組件不承受壓力，尤其是在后期壓榨期時因泵在大壓力下，其創(chuàng)新密封結(jié)構(gòu)設計，保證軸封處基本達到無泄漏。

2.雙級葉輪的結(jié)構(gòu)設計
  該泵采用雙主泵體，雙主葉輪的結(jié)構(gòu)設計，解決了單泵單葉輪泵在入料初期時振動和噪音過大、性能曲線平坦、葉輪流道窄、通過性能差等缺點非常適合壓濾機入料時應阻力的變化來實現(xiàn)大流量低壓力喂料與小流量、高壓力過濾的要求。

3.雙葉輪泵比單葉輪泵抗耐磨性更好
  因雙葉輪泵以較低的葉輪出口線速度獲得更高的泵出口壓力從而克服了單葉輪泵為增加壓力而增加葉輪線速度，而導致葉輪、泵殼磨損加劇的缺點，有效的提高水泵等過流部件的壽命。

4.應用范圍廣
  該產(chǎn)品可采用鑄鋼、高鉻鑄鐵（耐腐耐磨材料）、不銹鋼等多種材質(zhì)制造，可適合不同的介質(zhì)需求，用戶選用的范圍更廣。

5.葉輪與泵壁的間隙可調(diào)
  獨特的軸承箱設計，用戶在常時間使用后，因磨損造成壓力下降時，可通過調(diào)整葉輪與泵壁的間隙來繼續(xù)保障水泵的高壓力，提高了水泵的使用壽命、延長了大修周期，克服了傳統(tǒng)單葉輪壓濾泵因磨損壓力下降快，經(jīng)常更換葉輪使用壽命短等缺點。

Sludge filtration dehydration is driven by the pressure difference on both sides of the filter medium, so that the sludge moisture is forced to b the filter through the filtration medium, and the solid particles are intercepted on the medium to b a filter cake, so as to achieve the purpose of sludge dehydration. Sludge filter machine is a mechanical force on the side of the filter medium to achieve filtration machinery, mainly used for sludge (water) solid-liquid separation. Sludge filter machine is mostly used in papermaking, starch, alcohol, vitamin C Engineering and other industries of industrial sludge dewatering water sludge, through the sludge pump to the sludge mixing tank, while adding coagulant for full mixing reb, and then into the belt sludge pressure cloth mud, sludge evenly distributed to the gravity dewatering zone, and in the two-way channeling and gravity of the mud rake, With the movement of the Dewatering filter belt, the sludge quickly takes off the free water of the sludge. Due to the long design of gravity dewatering zone, maximum gravity dehydration is achieved. The flipped sludge enters the ultra-long wedge-shaped pre-pressure dewatering area to remove the sludge from the gravity zone slowly.

所有的污泥的漿泵主要是否有漏泥現(xiàn)象發(fā)生還有就是這些污泥泵的軸承以及盤根的密封。一般是在半個月就需要檢查一下。對液壓站的檢查，包括液壓液體的含量，液壓站的液體壓力系數(shù)。這是因為液壓站是隔膜壓濾機的重要動力部分，它的是否正常工作，關系到隔膜壓濾機過濾室的壓力，其更為重要的就是維持濾室的恒壓情況。空氣壓縮機以及調(diào)速電機的觀油窗需要檢查，新設備在購買時已加好潤滑油，一般是在一個月的時間內(nèi)再繼續(xù)檢查一下。通過檢查氣孔的閥門啟動來檢查控制這些氣體方面的內(nèi)容，還有就是減壓閥的檢查。對濾板的檢查，廂式隔膜壓濾機的濾板初期，就可以看出濾板的好壞，檢查濾板的氧化情況；濾板在長期被水侵蝕的情況下，濾板的含水狀況，和被水侵蝕的深度。
