It is understood that the new special scaffolding is mainly to fix the eye plate on both sides of the segmented closing mouth. After the ship platform is closed, a new type of special scaffolding is set up through the eye plate, so that the scaffolding is only used in the construction area of ​​the closing port.
The success of the new dedicated scaffolding pilot has not only changed the practice of large-scale scaffolding in the past, but also saved a lot of manpower and material costs. First, in the past, large-scale scaffolding required about 20 people, and now only needs about 5 people, which greatly saves labor costs. Second, in the past, large-scale scaffolding required 62 tons of materials, now only 13 tons; At the stage, the large cabin was painted and finished, leaving only the closed mouth, which changed the previous practice of overall sanding and overall painting, and reduced the labor cost of painting and painting.
The success of the new dedicated scaffolding pilot provided valuable experience for follow-up promotion and was a breakthrough in the construction of scaffolding by CSSC Chengxi.
The forced circulation pump does not rely on the centrifugal force of the impeller to the liquid, but uses the thrust of the rotating impeller blades to make the sent liquid flow along the direction of the pump axis. When the pump shaft is driven by the motor to rotate, because the blade has a certain helix angle with the axis of the pump shaft, a thrust (or lift) is generated on the liquid, and the liquid is pushed out and discharged along the discharge pipe. When the liquid is pushed out, a partial vacuum is formed at the original position, and the liquid outside will be sucked into the impeller along the inlet pipe under the action of atmospheric pressure. As long as the impeller keeps rotating, the pump can continuously suck in and discharge liquid. The forced circulation pump works by using the horizontal thrust along the direction of the pump axis generated by the rotation of the impeller, so it is also called a horizontal axial flow pump. Mainly used in the evaporation of diaphragm method caustic soda, phosphoric acid, vacuum salt production, lactic acid, calcium lactate, alumina, titanium dioxide, calcium chloride, ammonium chloride, sodium chlorate, sugar, molten salt, paper, waste water and other industries. Concentration and cooling, in order to improve the production capacity of the equipment, increase the heat transfer coefficient of the heat exchanger for forced circulation. Therefore, it can also be called an axial flow evaporative circulation pump.
