You are here : Mechanical seal life
Shaft and bearings must have high strength and stiffness and reliability. Trapezoidal screw connection of the impeller generally able to withstand heavy loads, in the case of heavy loads using plain thrust bearings, and ball bearings generally used in light load conditions.
Radial slurry seal, thus allowing the shaft skewness larger than ordinary pumps, which will limit packing and mechanical seals to some life. So generally use a shorter shaft that allows the skewness is also small, can improve the life of the stuffing. Cavity should be sealed into the general high-pressure water to dilute the material to extend the service life of the pump; If you can not dilute the material, the introduction of seal can be used, generally used for single-stage slurry pump in, but there will be a 3% efficiency Reduced.
Mechanical seal generally use part of the balanced structure, this time can be used to cool the transmission fluid; in some cases the pump may occur idling, double mechanical seal must be used at this time. In light load conditions, using the general mechanical seal; in heavy conditions, must be a special mechanical seal.
Generally use the pump casing made of elastic material strength may be too small to withstand greater pressure load, so it should add a layer of casing, known as double-wall structure, material generally used in hard metal, rubber or polyurethane resins. For large pumps, taking into account the size and cost constraints, can be used bolt structure.
d. the impact of solid particles on centrifugal pump
Slurry flow - lift curve more gentle, and the flow resistance of pipelines the specific role of spring roll machine with the flow of losses will increase slowly, pipeline characteristic curves and performance curves of the angle is very small, making the head A small change will cause significant changes in flow.
Slurry general wear and tear is very serious part of life sometimes just a month. So using the right material is a key factor in pump design. Sliding wear is mainly due to erosion and particle impact.
