introduction：4.1.1Centrifugal pump The liquid viscosity is not greater than the conveying temperature650mm2/S，Otherwise, the efficiency of the pump decreases greatly。（When viscosity is greater than650mm2/Swhen，The performance of the centrifugal pump is greatly reduced，Generally do not choose centrifugal pump，But because the centrifugal pump infusion does not pulsate，No need for safety valves and simple flow regulation，Therefore, centrifugal pumps are often seen in chemical production for conveying viscosity1000mm2/SLiquid of...）。 Large flow，And the head is relatively low The dissolved or entrainment gas in the liquid is not greater than5%（volume） liquid

introduction： one、Improve the coating ability of metal surface The coating phosphating film is porous，Uniform and fine，The paint seeped into the pores，Increase the adhesion of the coating。At the same time, the modified low zinc film can resist the corrosion of electrophoretic paint，Enhanced electrophoretic effect。All these are conducive to improving the phosphating film of the coating product+Corrosion resistance of organic coatings。The corrosion resistance of steel surface after phosphating is higher than that of direct coating without phosphating}2times。The effect of phosphating film on coating is as follows。 ①Provide interprocess protection，To avoid causing secondary rust。 ②Prevent chemical reactions between the coating and the substrate。 ③Mitigation of coating breakage，Rust in the paint

introduction：Heat treatment residual force refers to the final residual stress of the workpiece after heat treatment,Shape of the workpiece,Both size and performance make a huge difference。When it exceeds the yield strength of the material,It causes the deformation of the workpiece,When the strength limit of the material is exceeded, the workpiece will crack,Thats the pernicious side of it,It should be reduced and eliminated。However, under certain conditions, the stress is controlled to make it reasonably distributed,The mechanical properties and service life of the parts can be improved,Turn harm into good。The stress distribution and change law of steel during heat treatment are analyzed,It is of profound practical significance to improve product quality to make it reasonably distributed。For example, about surface residual pressure
