Installation of electromechanical equipmentIt has also begun to develop towards digitalization, automation, intelligence, and flexibility, entering a new stage of modern equipment. There are many types of electromechanical equipment, and there are various classification methods. As people's living standards continue to improve, their demand for electromechanical equipment in daily life is increasing. From vehicles to various household appliances, computers, printers, and other electromechanical products have become indispensable parts of daily life. Electromechanical equipment has detailed classifications, commonly used in industrial equipment asset management, electromechanical product catalogs, and cataloging in data manuals.
In addition, electromechanical equipment can be divided into three categories by use: industrial electromechanical equipment, information electromechanical equipment, and residential electromechanical equipment. Advanced electromechanical equipment not only greatly improves labor productivity, reduces labor intensity, and enhances the production environment, preventing humans from laboring, but as one of the national industrial bases, it also has a direct and important impact on a country's technological level and comprehensive national strength, as well as its technological level and overall national strength.
With the improvement of standardization and modernization of production equipment, especially the application of automated equipment, the installation and commissioning process of electromechanical equipment has become increasingly complex and specialized. The equipment installation specialty is gradually shifting toward technology-intensive development, which has givenElectromechanical equipment installation projectsThe construction period created considerable obstacles.
This requires the electromechanical equipment installation schedule to carefully consider the time forecasts for each process, balancing the needs of engineering production and technical commissioning. Generally speaking, common electromechanical installation issues mainly include the following points:
1) Bolt connection issues.
Basic assembly of bolted connections is electromechanical installation, but improper operation and overly tight connections may cause long-term effects of bolts due to electromagnetic and mechanical forces, metal fatigue, leading to shear, screw thread slippage, and other loose assembly parts, leading to hidden accidents. Especially used for electrical engineering conductive current bolt connections. When installing good electromechanical equipment, bolts and nuts should be tightly machined, and mechanical and heating effects should be pressed and then compacted to avoid increased contact resistance causing loose welding, which could lead to increased contact resistance and oxidation resistance, triggering a series of chain reactions that cause connection points to overheat, blow out fuses, and cause grounding short circuits or broken wires.
2) Vibration issues.
The causes of vibration problems generally include three aspects:
(1) Pumps: mainly caused by bearing clearance, poor concentricity between rotor and housing, or strong friction between rotor and stator.
(2) Motors, whose causes include large bearing clearance, rotor imbalance, or uneven air gap with the stator.
(3) Installation operation: If the operating parameters deviate too much from the rated parameters, it can easily cause unstable pump operation, such as vibration caused by unstable flow control at the outlet valve. Therefore, the installation process should be as close to the rated parameters as possible.
3) Overcurrent issues.
There may be three possible reasons for this: pump bearing damage, foreign objects inside the equipment; Low motor overload current setting, high circuit resistance; The medium used in process operations exceeds the pump's design capabilities due to its high density or viscosity.
Industrial electromechanical equipment refers to equipment used in manufacturing enterprises, such as various machining equipment used in machinery manufacturing, automated production lines, industrial robots, as well as machinery used in other industries like textile machinery and mining machinery, all of which belong to industrial electromechanical equipment. With continuous technological improvements, traditional mechanical equipment has entered a new stage of mechatronics integration, with its application scope constantly expanding. Since the 1960s, computers have gradually become widespread in the research, design, production, and management of the machinery industry, creating conditions for the mechanical manufacturing sector to develop toward greater complexity and precision.
