When vacuum components such as valves, water traps, vacuum cleaners, and vacuum pumps are connected to each other, the suction pipe should be short, the pipe guide capacity should be large, and the pipe diameter should generally not be less than the pump port diameter. This is an important principle in vacuum system design. When designing a vacuum system, both installation and maintenance convenience should be considered simultaneously. Sometimes, in order to prevent vibration and reduce noise, it is allowed to install mechanical pumps in the pump room near the vacuum chamber
2. Mechanical pumps (including Roots pumps) experience vibration, and in order to prevent the vibration from affecting the entire system, hoses are usually used for vibration reduction. There are two types of hoses, metal hoses and non-metal hoses. Regardless of which type of hose is used, it should be ensured that it will not be compressed under atmospheric pressure. 3. After the vacuum system is completed, it should be easy to measure and leak. Production practice tells us that vacuum systems are prone to gas accumulation during operation, which affects production. In order to quickly find the leakage hole, segmented leakage detection should be carried out. Therefore, each part that is closed with a valve should have at least one measuring point for detecting leaks.
4. The valves and pipelines for egg preparation in the vacuum system should ensure short pumping time, easy use, and reliability. Generally, there is a steam flow pump as the main pump (dispersion pump or oil booster pump) in a system with a mechanical pump as the front stage pump. In addition to the front stage pipeline (the steam flow pump pipeline electrically connected to the mechanical pump), there should also be a vacuum pipeline (the vacuum chamber pipeline passes through the machine city pump). Secondly, a snow high vacuum width is set between the vacuum chamber and the main pump (he called the main pump), a front stage pipeline network is set on the front stage pipeline (he called the vacuum protection network), and a pre vacuum pipeline network is set on the pre vacuum pipeline (he called the low vacuum wine). The high vacuum class on the main pump cannot speak under the vacuum voltage state under the network difference, but should speak under the atmosphere on the smoke cover. Under the influence of Leli, this city has obtained the central mother certificate from the Electrical Union, ministerial level management inquiry photos, and pre direct air and road network office. The old Lianshen Gate has been opened under the influence of Dali and Leli, and the main network of Jingyao Shanniu Pump has been trained in the straight letter system, which is rich in steam flow beans, The fake collection of the front level camp road should be carried out by the Yongshan cattle pump, and the pre straight air pipeline should be equipped with a male exhaust limit on the empty room and mechanical original flood pipe. When the machine city stops working in the mine, the cabinet door can be opened immediately, and the inlet of the loose pump component into the atmosphere can be opened to prevent the mechanical pump oil from returning to the camp road cleanly. Therefore, the smoke gate market should be electrically connected with the mechanical equipment, and necessary gas and smoke should not be installed on the straight air room for material delivery and return. The price of smoke doors should be relatively high when traveling from old shops to hotels, in order to prevent weak components in the vacuum chamber from being damaged due to excessive pulse oil. The size of the vent valve is related to the volume of the vacuum chamber, and it should be considered that the venting time is not too long, otherwise it will affect the work
5. The design of the vacuum system should ensure non gas stability, easy installation, disassembly, and maintenance, convenient operation, and interoperability between components. In order to achieve fixed exhaust during operation, it is required that the cow pump components can be fixed, each smoke door can be operated, the seal can be sealed for years, the vacuum flow seal components can be electrically good, and the connection of the spare straight air components should be made using standard dimensions to ensure interoperability. In the design of the vacuum system, the maximum dimension of each closed pipeline should be adjustable. In the past, adjustable dimensions were solved through hoses. Nowadays, in the design of the system, most hoses are not used. By improving the precision of vacuum components and connecting them, the maximum dimension should be adjusted. In principle, sealing rubber rings are used on the flange to solve installation errors, improve the strength and stiffness of the system, and reduce the support used on the system, Make the system more aesthetically pleasing.
