從安裝使用要求選擇渣漿泵的型式
(1)臥式泵:是比較普遍的結(jié)構(gòu)型式，使用比較廣泛。其泵的結(jié)構(gòu)簡(jiǎn)單，使用可靠，對(duì)多級(jí)泵使用平衡盤平衡軸向力時(shí)只能選用臥式結(jié)構(gòu)。
(2)立式泵:安裝面積小，可減少泵站的面積，降低造價(jià)，所以一般船用泵采用立式結(jié)構(gòu)較多。
(3) 立式浸沒泵:不但占地面積小，并且泵的起動(dòng)不需要灌液或抽真空，較適合于無(wú)人看管的自動(dòng)控制下使用: 并且不易產(chǎn)生氣性。其缺點(diǎn)是結(jié)構(gòu)較復(fù)雜，維修較困難，易腐蝕，泵的壽命短。
(4)立式管道泵: 因?yàn)楸玫奈?、吐出口在同一水平線上， 所以特別適合于管道中的安裝，并且占地面積較小。
(5)潛水泵:是將泵和電機(jī)一起放入水中運(yùn)行，所以安裝簡(jiǎn)單方便，使用也很方便，泵啟動(dòng)前不需要灌泵或抽真空，因泵在液下，不易發(fā)生汽蝕。它的缺點(diǎn)是泵的壽命相對(duì)較短，維修較困難。
(6)自吸式:泵的啟動(dòng)不需要底閥、灌泵或抽真空。自吸泵如果配用內(nèi)燃機(jī)為原動(dòng)機(jī)時(shí)，移動(dòng)使用很方便，常用于工程施工時(shí)移動(dòng)場(chǎng)合下。如果輸送介質(zhì)中含氣量較多時(shí)使用自吸泵較好。渣漿泵廠家
Select the type of slurry pump according to the requirements of installation and use
(1) horizontal pump: it is a relatively common structural type and widely used. The structure of the pump is simple and reliable, and the horizontal structure can only be used when the balance plate is used to balance the axial force of the multi-stage pump.
(2) vertical pump: the installation area is small, which can reduce the area of the pump station and reduce the cost, so the vertical structure is widely used in general marine pumps.
(3) vertical immersion pump: it not only occupies a small area, but also does not need filling liquid or vacuumizing when the pump is started, so it is more suitable for the use under the automatic control of unattended, and it is not easy to produce gas. Its disadvantages are complicated structure, difficult maintenance, easy corrosion and short pump life.
(4) vertical pipeline pump: because the suction and discharge outlets of the pump are on the same horizontal line, it is particularly suitable for the installation in the pipeline and occupies a small area.
(5) submersible pump: the pump and motor are put into the water for operation, so the installation is simple and convenient, and the use is also very convenient. Before the pump is started, there is no need to pump or vacuum, because the pump is under the liquid, it is not easy to have cavitation. Its disadvantage is that the service life of the pump is relatively short and the maintenance is difficult.
(6) self priming: the start of the pump does not require bottom valve, pump filling or vacuum pumping. If the self-priming pump is equipped with an internal combustion engine as the prime mover, it is very convenient to move and use, which is commonly used in the moving occasions during the construction of the project. It is better to use self-priming pump if there is more air content in the conveying medium. Slurry pump manufacturer
