The Influence Of The Quality Of Pump And Valve Casting Part On Mechanical Product Performance

The influence of the quality of Pump And Valve Casting Part on mechanical product performance

The quality of the Pump And Valve Casting Part includes appearance quality, inner quality and quality of use. Appearance quality refers to surface roughness, surface defect, size deviation, shape deviation and weight deviation. The internal quality mainly refers to the chemical composition, physical properties, mechanical properties, metallographic structure and the holes, cracks, inclusions and segregation of the castings. Service quality refers to the cast copper piece durable ability to work under different conditions, including the wear-resisting, corrosion resistance, resistance to chilling excitation properties, such as fever, fatigue, shock absorption, and by cutting resistance, weldability, etc. Process performance.

The Pump And Valve Casting Part are caused by various factors, such as stomata, pinhole, slag, crack, pit etc. The commonly used repair equipment is argon arc welding machine, resistance welding machine, cold welding machine, etc. For defects of quality and appearance, the casting defects can be repaired by high heat and fast welding machines such as argon arc welder.

The quality of Pump And Valve Casting Part has a great influence on the performance of mechanical products. For example, the wear resistance and dimension stability of machine tool castings directly affect the precision of machine tool. All kinds of pump and hydraulic parts of impeller, shell lumen size accuracy and surface roughness and contour line, directly affects the working efficiency of the pump and the hydraulic system, energy consumption and the development of the corrosion, etc.; The strength of the cylinder block, cylinder cover, cylinder liner, piston ring, exhaust pipe and so on are the strength and the heat resistance of the casting, which directly affect the working life of the engine.

Pump And Valve Casting Parts are carbon content above 2% (mass fraction) of the iron carbon alloy, the material is only a small amount of the carbon in the form solid solution with iron, mostly in the form of graphite or cementite exist, because the graphite will reduce the deposition potential of hydrogen, which hindered the deposition of zinc.

At the same time due to the material surface is too rough, across the sand holes and shrinkage cavity, composition containing phosphorus, sulfur, silicon and graphite and titanium, and other elements, thus appeared the overpotential of hydrogen in the process of plating is too low, easy to cause hydrogen evolution, brings to the metal deposition difficulties; And pickling and can increase the adsorption quantity of hydrogen atoms, part into hydrogen adsorption of hydrogen atoms, in addition to send out into the air, it will be a part of the hydrogen atoms to spread in the cast iron matrix, the more hydrogen pressure, not only affect the pumps and valves, the mechanical properties of casting itself, in the process of electroplating can also cause a large amount of hydrogen evolution, not only seriously influence the coating fastness, still can cause JiJu current efficiency drops, to further increase the difficulty of electroplating.

The application of Pump And Valve Casting Part is not widespread. Casting process simulation is a necessary part of casting production. Computer simulation of casting industry in China started relatively early, while the core computing part development ability is stronger, but the overall software package ability is poor, lead to the commercialization of the mature software development is far behind the developed countries, quite a number of foundry enterprises of computer simulation technology, the lack of trust. Although this kind of situation has improved somewhat, it is rare to see that it can play its role in the enterprises that purchased the Pump And Valve Casting Part. It is urgent to train employees in software application.

The transformation from labor and resource-intensive to technology-intensive capital intensive in the way of growth, from the extensive pollution to the green intensive transformation,

Form some reasonable structure, high level of overall production, combined with the research and development and education training base, can constantly to the enterprise transportation professionals, continually develop high quality, high grade casting material varieties, to meet the increasing needs of the casting material, gradually increase the intensity of the export of technology at the same time.
