渣漿泵易損件壽命的影響因素
渣漿泵所抽送固液混合物的多種多樣，固液混合物磨蝕性程度變化范圍很大，泵運行
條件千差萬別，這些為研究具有相當(dāng)精度的確定易損件壽命的方法增加了難度，甚至固體顆粒特性中有一個特性變化，例如硬度系數(shù)變化，將導(dǎo)致壽命有很大的變化。例如，當(dāng)普氏硬度系數(shù)從15~17降低到10~12時，由相同材質(zhì)制作的泵易損件壽命增加0.5~1倍，根據(jù)不同運行條件下的統(tǒng)計資料(表3-7- 7)，確定泵零件的壽命。
同時，零件壽命不是用小時而是用零件完全磨損前泵所抽送固體物料的數(shù)量表示。
根據(jù)現(xiàn)有運行統(tǒng)計資料，可以計算泵在所抽送固體顆粒和制作零件材質(zhì)的特性變化時零件的壽命。
渣漿泵零件發(fā)生故障前的工作時間(磨蝕性材料的數(shù)量，即在第一次故意和強制修理或者更換之前可以通過零件的數(shù)量。渣漿泵廠家
Influencing factors of service life of vulnerable parts of slurry pump
There are many kinds of solid-liquid mixtures pumped by slurry pump. The abrasion degree of solid-liquid mixtures varies greatly and the pump operates.
Conditions vary widely. These methods for determining the life of vulnerable parts with considerable accuracy increase the difficulty. Even there is a characteristic change in the characteristics of solid particles, such as the change of hardness coefficient, which will lead to a great change in the life of vulnerable parts. For example, when the Pulser hardness coefficient decreases from 15 to 17 to 10 to 12, the service life of vulnerable parts made of the same material increases by 0.5 to 1 times. According to the statistical data under different operating conditions (Table 3-7-7), the service life of pump parts is determined.
At the same time, the service life of parts is not expressed in hours, but in the quantity of solid materials pumped by the pump before the parts are completely worn out.
According to the existing operation statistics, the service life of the pump parts can be calculated when the solid particles pumped and the material properties of the parts changed.
The working time before the parts of slurry pump fail (the quantity of abrasive materials, that is, the quantity of parts that can be passed before the first intentional and forced repair or replacement.
