Liquid desulfurization pump in the environment under the influence desulphurization pump parts of wear elements

under the liquid desulfurization pump use range is very wide, suitable for many industries, especially in the place of some conditions apply, and transport medium is with acid, alkali, corrosion, or more toxic gas, etc. Using the desulphurization pump can gave most of the sulfur removal, can reach our requirement for environment protection. In this harsh environment influence desulphurization water pump wear parts is also relatively more, the elements of rough classification is the following:

1, the erosion wear desulphurization pump flow across from solid particles in the operation process down the slurry erosion wear parts appearance, wear and erosion wear can be divided into cutting deformation fatigue wear two wear form. For example, the guard plate wear important reason is the solid particles with larger viewpoint to guard strong shocks, belongs to the cutting wear

2. Spring austerity, the greater the sealing effect is better. In fact, if spring austerity is too big, will lead to the friction pair of abrasive wear, instantaneous burning loss; Excessive squeeze will lose spring ring end face, adjust activities lead to seal failure.

3。 Seal the tighter, the better. Static seal ring basically stopped, the sealing effect is relatively better, but too tight is harmful. One is the static deformation of seal ring is too big, affect the sealing effect; Two is mostly static ring material graphite, generally brittle, too much stress can easily cause cracking; Three is to install apart is difficult, easy to damage the stator. Integrated circuit.

shaft seal part: there are three forms of the shaft sealing, vice impeller shaft seals and packing seal, mechanical seal.

( 1) Desulphurization pump vice impeller shaft seal: under liquid pump inlet pressure values are not greater than 10% of the water pump outlet pressure value at the time of the single stage or multistage tandem third grade pump, can choose vice impeller shaft sealing, vice impeller shaft seal has not dilute pulp, the sealing effect is good and other advantages.

( 2) Under liquid desulfurization water pump packing seal: packing seal structure is brief, convenient maintenance, need to use shaft seal water, about is not suitable for the condition of vice impeller shaft seal and pump suction using condition can choose packing seal.

( 3) Mechanical seal: not suitable for the above two kinds of shaft seal condition, selection of mechanical seal, shaft seal cutting part of the maintenance times.

transmission parts: this series of pump were picked from the same series of transmission, including the bracket and bearing components, pump shaft diameter is large, rigid good, the cantilever is short, not twists and turns and oscillation in bad condition. Bearing using single row circular cone roller bearings and angular contact ball bearing combination, pump to bear a large axial and radial load, bearing USES lithium grease lubrication, the lubrication of strengths lie in: high oil film strength; Oil adhesion is good, not easy to drain, use for a long time; Liquid desulfurization pump seal a brief, both ends of the bearing body is equipped with sealed end cover, can effectively prevent pulp and other contaminants into the bearing.
