The desulfurization submerged pump in the points of attention in the actual work

in many industrial enterprises, the desulfurization of submerged pump apply variety are many, it is necessary for the transmission of different media with different varieties of the pump. Not only in materials, types, specifications, and in the design of the pump is there are many different. Desulfurization submerged pump is an one of the chemical pump, took the desulfurization submerged water pump, its up to fit what standard?

desulfurization submerged pump at the time of maintenance, it is necessary for mechanical equipment outside collation and parts, parts finishing and can be divided into evaluation before finishing, arrange and parts assembly line before plating cover or adhesive prepared ahead of time to sort out before work. If not pass finishing will cause serious damage to the application of machinery and equipment quality. Coordinate the external mechanical equipment is very short, it is necessary to remove dirt and rust on pump body, then do a good job of the corrosion protection.

in desulfurization submerged pump calculation error or incomplete, if choose the disc spring loads, if pressure is too high, more than the gasket and the bolt material itself to the limit, can also lead to leakage.

in this case, it is necessary to use coil spring for compensation, compensation ability than the required minimum sealing preloading, less than 75% of the material yield limit.

desulfurization submerged pump actual work usually two kinds of errors.

1。 Selection pressure is too small, according to the physical properties of the bolt pre-tightening, relaxation prestressing force if 30%, is not to seal the required minimum, the equivalent of installation disc spring;

2。 Selection pressure: if the elasticity of the coil spring to limit or to stem lock, leading to more than 75% of the internal taper coil spring trip lead to permanent deformation, equivalent to enlarge artificial bolt pre-tightening relaxation force, more harmful.

3。 Heat bilges cold shrink, in the same mechanical equipment, bolts, washers, flanges, packing because material is different, in the same temperature range, the speed of the bilges cold shrink is different also, so in the temperature range, the desulfurization submerged pump manufacturer originally pre-tightening force will be reduced, with overlapping, relaxation degree of prestressing force will become geometry. Stage expanding lead to leakage.

4。 Desulfurization submerged pump new better than the old. , in contrast, the use of new mechanical seal is better than the old mechanical seal, but if the quality of the new mechanical seal or data has not been properly selected, the size of the new desulfurization submerged pump mechanical seal error will affect the sealing effect. In polymer and permeability medium, it is best not to replace the static ring without excessive wear. Because the static ring at the long time rest, static ring polymer and the sediment in a body, has a good sealing effect.
