In the 1980s, my country developed aluminum radiators; in the 1990s, my country paid great attention to the product development of aluminum radiators. During this period, my country’s aluminum radiators were very active in research and development and the application of patent projects. Extruded alu ...
Centrifugal pumps (except self-priming pumps) must be filled with water before starting the pump and the water inlet pipe, otherwise the water pump will not work. The centrifugal pump does not produce water after it is started, which is often caused by the fact that the air in the pump has not been ...
Cleaning is an important part of the pump repair work, and the cleaning quality has a great influence on the repair quality of the machinery. The use of correct cleaning methods to improve cleaning quality and reduce costs is one of the issues that repair workers must consider. ...
The main cause of this kind of rust is the moisture, dust and SO2, H2S, CO2 and other gases in the atmosphere. In the hot and humid summer, especially in places with large air flow, this kind of bearing is easy to produce rust on the periphery of the bearing stack. ...
Plateau motors operate at high altitudes, due to low air pressure, poor heat dissipation conditions, and losses will increase and operating efficiency will decrease. Therefore, the same, the rated electromagnetic load and heat dissipation design of motors running at different altitudes are different ...
Ensuring the quality of die-casting aluminum alloy smelting is the most important step in die-casting production. This article combines the company’s specific conditions to briefly introduce the slag and gas generated during the smelting process of die-cast aluminum alloy ADC12. At the same time, it ...
When the pump is dynamically balanced, the entire rotor parts should be made together. The impeller is replaced, and the balance point has also changed. It needs to be re-aligned. If it is an ordinary single-stage pump, it is not necessary because of its residual imbalance. ...
This article introduces a manufacturing method of environmentally friendly energy traction motor and generator stator base. Through the design of die-casting mold, W-shaped water channel and W-shaped female groove and weld protection flange are cast on the inner cylinder; W-shaped male groove is cas ...
As a typical lightweight metal, aluminum alloy is widely used in foreign automobiles. Foreign automobile aluminum alloy components mainly include pistons, cylinder heads, clutch shells, oil pans, bumpers, heat exchangers, brackets, wheels, body panels and decorations parts etc. ...
Although the die-casting process is better than ordinary casting technology, the surface is smoother, the wall is thinner, the precision, the strength is higher, the process is simple, the production efficiency is high, and it can greatly save raw materials, but the die-casting process is only suita ...
The crack failure of aluminum alloy die-casting mode will not only affect the mold production quality and production efficiency, but also increase the production cost. In reality, the reasons for the cracking and failure of aluminum alloy die-casting molds are diverse. For example, liquid metal has ...
