Three reasons of scaling on gypsum slurry pump

the present scientific research thought, gypsum slurry pump scale there are three reasons:

( 1) Accumulation of scaling. Due to the architecture design is not science, mixing, such as not enough lead to serous water flow is too low, not into the particles in the slurry, will lead to solid particles in the vessel or piping piling up the bottom;

( 2) The crystals into scale. When converted into plaster of Paris in the saturated state of the slurry density beyond the critical value of all other nuclear results contrast will slightly in the slurry when the crystal nucleus, and the tower body surface gradually become for hard scale; When CaSO3 ⋅ 1/2 h2o contrast was beyond the critical value contrast of its all other nuclear effect will occur at the tower wall surface soft, posture is very simple tartar very well;

( 3) Wet hard scale. Because of high temperature smoke volatile effective adhesion on the part of the tower wall accumulation of serous fluid, key in gypsum slurry pump smoke entrance to the first layer nozzle in the middle, after a shower to soot entrances in the middle, forced air oxidation air oxidation of ventilation duct exit system software 'wet - 'Border area.

gypsum slurry pump wet area work interface and the following column wall, supporting frame, the nozzle, all scale. Level of demister leaves the crystals of hard cover and architecture, secondary demister blocked, but congestion level of light in the level of demister, obstruction to compare the spongy plaster of Paris, mist eliminator cleaning spray water to remove dirt. Operation period, the material temperature forecast region will shift, shaft will more or less to the earth's axis force, this time must be connecting shaft device has a greater range of motion. Plaster slurry pipeline layout please according to the following contents:

( 1) When into the standard of water pipe and water pump suction inlet is not the same, according to the axial force of among them into reducer to join them, to remove bubbles.

( 2) inlet to be short and concise, equipment NPSH must go beyond the pump NPSH, in the transportation net weight density of slurry is highly recommended to use backflow installation method.

( 3) Strong water inlet and outlet of the bolt support, as the force on the pipeline is not simple results on the pump. Additional external force when the pump to the pipeline when abnormal.

( 4) Gypsum slurry pump outlet way to install valve to adjust the pump operation load point, gate as far as possible near the pump outlet nozzle installation, generating set after installation, check the water pump seal working pressure of tap water and traffic.
