Application characteristics of mechanical vacuum pump in steel making industry
1. low energy consumption
The application of vacuum pump in steelmaking enterprises mainly includes mechanical vacuum pump and steam vacuum pump. Mechanical vacuum pump has the characteristics of low energy consumption, and its energy consumption is about 10% of that of steam pump in specific operation. Therefore, the application of mechanical vacuum pump has greater advantages from the aspects of energy consumption application and cost expenditure. In addition, compared with the steam vacuum pump, the vacuum pump system realizes the controllable operation of working steam in the whole process, which plays an important role in improving the operation efficiency of the system.
2. environmental protection
The metal smelting industry is one of the heavy pollution industries. Based on the analysis of the current implementation of environmental protection policies in China, one of the main advantages and characteristics of the application of mechanical vacuum pump in the production of steel-making enterprises is environmental protection. The main reason is that the mechanical vacuum pump equipment does not produce any pollutants during operation.
The application of vacuum pump system in steel-making production and automatic operation are the main features of the system. Analysis of the advantages of automatic operation, the main features are: less reactive power loss in the operation of equipment, high efficiency, and high stability in the actual operation. It reduces the probability of potential safety hazards caused by operation delay and inadequate coordination between equipment. At the same time, it plays an important role in improving the quality of safety production in the development of steel-making enterprises.
Operation principle and development trend analysis of mechanical vacuum pump
The working principle of mechanical vacuum pump in operation is the process of aspirating, compressing, exhausting and continuous aspirating through the circulation of each component. According to the difference of the internal structure of the mechanical pump, there are three parts: the suction cavity, the compression cavity and the exhaust cavity. Specifically, during the operation of the equipment, the air inlet is used for suction first, and then it enters the compression chamber to compress the gas continuously. When the pressure of the suction chamber is reduced, the suction operation is continued. The compression chamber is compressed to the design strength and enters the exhaust chamber, and then it achieves the effect of continuous extraction and exhaust of the gas by circulating operation.
In addition, from the operation characteristics of mechanical vacuum pump, operation principle, as well as the current situation of operation power consumption, as well as the strengthening of China’s environmental protection policy, the implementation of supply side reform system. As for the application of mechanical vacuum pump in steel-making enterprises, it has the advantages of low application cost and high application stability. Therefore, in the future development of steel-making industry, the application of mechanical vacuum pump has great application value.
Analysis on the application of mechanical vacuum pump in steel-making industry
1. Reasonable selection of cooling system
In order to ensure the stable operation of the vacuum pump system, the application unit should install the cooling system device for the vacuum pump system in practical application. The installation and application of the cooling system are analyzed to ensure the stability of the vacuum pump system in operation. In addition, considering the cooling effect and the stability of the cooling medium application, the gas cooler is suitable for the application of the cooler in the vacuum pump system.
2. Implement the installation and application of dust remover
The difference between vacuum pump system and steam vacuum pump is that it is sensitive to dust substances in operation. Therefore, in order to ensure the safe and stable operation of vacuum pump system and implement the installation and application of dust remover device in actual development, it is the main attention in the operation of vacuum pump system. In the specific implementation of the installation of the dust remover device, the way of pre installation can be used to reduce the abnormal operation of the vacuum pump caused by the entry of foreign matters in the early operation or operation, so as to ensure the operation safety of the whole system.
3. Pay attention to the maintenance of equipment components
The application of vacuum pump system in steel-making production, from the overall production application environment and production process analysis, there are more pollutants, dust, and other debris in the operation environment of the equipment. The existence of this kind of impurity substance has caused great harm to the stable operation of vacuum pump system. At the same time, the safety of the application of vacuum pump system also has a certain impact. Therefore, in the actual development, the application unit should pay attention to the maintenance of equipment components in the operation of vacuum pump system. In the specific implementation of the operation and maintenance of the vacuum pump system, the application unit shall implement the cleaning maintenance, fixed maintenance and lubrication maintenance. Among them, the cleaning maintenance mainly aims at the exhaust hole, air inlet, air inlet pipe, air inlet filter screen, and cleaning maintenance.
In addition, impurities and debris shall be prevented from entering the vacuum pump during cleaning and maintenance, and the sealing surface protection operation shall be strictly implemented to avoid damage to the sealing surface during disassembly, cleaning and installation. In addition, during the installation operation, the number of screws and the accuracy and perfection of the position installation shall be ensured to avoid the fixation failure caused by the missing screws. In addition, a small amount of grease can be applied on the wall of the vacuum pump in the process of disassembling, washing and assembling the accessories, so as to ensure the safety and stability of the vacuum pump system in the later stage.
4. Implement the trial operation in the early stage of equipment application
The key points of the trial operation and attention of the mechanical vacuum pump are as follows: start the equipment operation for the trial operation of the vacuum pump, check and observe whether there is abnormal vibration and impact sound during the operation of the vacuum pump. In addition, if it is the first operation, the limit pressure of mechanical vacuum pump shall be tested to ensure that its operation performance meets the requirements of process production and relevant technical specifications. In addition, the operating temperature of mechanical vacuum pump in specific operation shall not exceed 70 ℃.
In the actual operation, the operation status of the equipment, as well as the temperature, pressure and power status generated in the operation shall be considered. When the application unit actually applies the mechanical vacuum pump, it shall also pay attention to the reasonable selection of the cooling system, the installation of the dust remover, the maintenance and renewal of the components in the equipment operation, and the trial operation before the equipment operation. In order to reasonably improve the application quality of the equipment, and ensure the safety and stability of the later steelmaking operation.
