China overhead line fittings, crafted from iron or aluminum, secure and support conductors in power lines. Various hardware types include clamps for wire installation, hanging rings for insulator strings, crimping and repair tubes for wire connections, and spacer bars for split wires. In addition, cable fittings for pole towers are utilized. These components not only fix and support wires but also assemble suspension insulators into strings, connecting and hanging them on tower cross arms. Design and manufacturing considerations prioritize strength, stiffness, and wear resistance for long-term use. Selection and configuration of hardware must align with specific line conditions to ensure the safe and stable operation of overhead lines. Installation Guide for Overhead Power Line Accessories There are 5 steps for the installation of electrical overhead line fittings: Preparation and Planning: Conduct a comprehensive site assessment considering terrain, weather, and load requirements. Assembly and Inspection: Assemble fittings according to manufacturer guidelines, ensuring all bolts and connections are securely tightened. Lifting and Attachment: Lift and position assembled fittings onto poles or towers, using appropriate lifting equipment. Alignment and Tensioning: Verify alignment and adjust if necessary. Final Checks and Documentation: Conduct thorough quality checks, addressing any issues identified during the inspection. The components of an overhead line, a crucial element in power transmission and distribution, consist of a well-coordinated system of essential elements designed to efficiently transport electrical energy from generation sources to end-users. At its core, an overhead line typically comprises conductors, supporting structures, insulators, and associated hardware. Conductors form the backbone of the overhead line, serving as the pathway for electricity to flow. These conductors are often made of aluminum or copper, chosen for their excellent conductivity and durability. Supporting structures, such as poles or towers, play a critical role in elevating the conductors above the ground and maintaining the required clearance. The design and placement of these structures are essential to ensure the stability and reliability of the overhead line. Insulators, often made of ceramic or composite materials, are strategically placed to electrically isolate the conductors from the supporting structures, preventing unintended paths for current flow. This is crucial for maintaining the integrity and safety of the system. Additionally, associated hardware such as clamps, connectors, and fittings are employed to secure and connect various components of the overhead line, ensuring a robust and reliable transmission network.
In biological sample centers or scientific research institutions, there are a large number of cells, strains, vaccines and other samples that need to be cryopreserved. The scientific research of these samples is of great significance, and their safety cannot be ignored. In addition, there are requirements for batch management and data collection. Vapor phase liquid nitrogen tanks are often chosen over aviation aluminum Dewars. Vapor-phase liquid nitrogen tank, also known as "stem cell liquid nitrogen tank", is named after it is often used to establish stem cell banks. It is different from ordinary liquid nitrogen containers. It has two storage modes: gas phase and liquid phase. The sample storage method is unconventional and its working principle is break the usual. Sample storage methods in gas phase liquid nitrogen tanks: Partition management, gas phase preservation! The inner tank of the stem cell liquid nitrogen tank is divided into two areas. The upper area is for samples, which is the storage area for stem cells, embryos, bacteria, etc.; the lower area is for liquid nitrogen storage only and does not contain any samples. The bottom position, which is the liquid nitrogen storage area, is equipped with an evaporator to provide evaporated nitrogen for sample storage to cool down. The sample is only "close" to the liquid nitrogen, but does not touch it, and the volatilized low-temperature nitrogen is used to store the cells. Working principle of gas phase liquid nitrogen tank: The principle is actually very simple, such as the use of liquid nitrogen evaporation cooling mentioned above! When the nitrogen in the sample storage area is insufficient to support the sample demand, the bottom evaporator starts working to supply liquid nitrogen to the upper part. This has the advantage of avoiding sample cross-contamination. The reason why I donâ??t mention its other storage mode - liquid phase is because the liquid nitrogen reserve in the container is large, much higher than that of conventional liquid nitrogen containers, and the evaporation loss of stainless steel is higher than that of aluminum alloy. When storing in liquid phase, replenish the liquid. Frequent and troublesome, difficult to use, only gas phase storage is recommended. In addition, the gas-phase liquid nitrogen tank also has high dual-gallery vacuum + high thermal insulation performance, which reduces heat conduction, reduces the evaporation rate of liquid nitrogen, and maintains stable pressure inside the tank. The built-in intelligent control management system is used for real-time detection and abnormal warning of temperature, pressure and liquid level to ensure the stability of the tank and the safety of stem cells.

The model of the slurry pump is selected based on the flow head provided on site. After the model is determined, the caliber of the slurry pump is also determined. However, the pipelines on site are not designed according to the caliber of the slurry pump. If the size is large What will happen if a large-diameter slurry pump is equipped with a small-diameter pipeline? Let's take a look. Many users think that this can increase the actual lift of the slurry pump. In fact, the actual lift of the slurry pump is the total lift minus the loss lift. When the slurry pump model is determined, the total head is certain; the loss of head mainly comes from the pipeline resistance. The smaller the pipe diameter, the greater the resistance, so the loss of head is greater. Therefore, after reducing the pipe diameter, the actual head of the water pump is not only It cannot be increased, but will decrease, resulting in a decrease in water pump efficiency. In the same way, when a small-diameter water pump uses a large water pipe to pump water, the actual head of the water pump will not be reduced. On the contrary, the loss of head will be reduced due to the reduced resistance of the pipeline, so that the actual head will be increased. Some users also believe that when a small-diameter water pump uses a large water pipe to pump water, the motor load will inevitably be greatly increased. As everyone knows, the liquid pressure is only related to the head and has nothing to do with the cross-sectional area of the water pipe. As long as the head is turned on, the size of the impeller of the water pump remains unchanged. No matter how large the pipe diameter is, the pressure acting on the impeller is certain. However, as the pipe diameter increases, the water flow resistance will decrease, resulting in an increase in flow rate and an appropriate increase in power consumption. But as long as it is within the rated head range, the water pump can work normally no matter how the pipe diameter is increased, and it can also reduce pipeline losses and improve water pump efficiency.

As we all know, liquid nitrogen tanks are used to store liquid nitrogen and preserve biological samples. They can maximize the low-temperature characteristics of liquid nitrogen. It is used in different industries such as medical research and industrial cold assembly. Small gas phase liquid nitrogen tanks, although also called liquid nitrogen tanks, are very different from traditional liquid nitrogen tanks. Then letâ??s start talking about where they differ. Small gas-liquid phase tank, it is a new type of liquid nitrogen biological container between the YDS series and YDD series. It has the same aviation aluminum material as YDS. The inner and outer tanks are made of the same material. It is relatively light but strong and has good thermal insulation effect. . It also has the same gas-liquid phase dual-mode storage and intelligent management system as YDD; and the only difference between it and traditional liquid nitrogen tanks is the storage mode! Different storage modes There is only one storage mode for traditional liquid nitrogen tanks, which is the liquid phase - the sample is completely immersed in liquid nitrogen. However, this is also its advantage. The temperature of frozen samples is relatively low, the storage time is longer and the maintenance cost is relatively low. However, there are also disadvantages. During use, you must always pay attention to the liquid level in the tank, replenish liquid nitrogen in time, and keep it covering the sample to avoid rapid evaporation of liquid nitrogen that affects sample safety. There are two storage modes for small gas phase tanks, gas phase and liquid phase. The gas phase uses low-temperature nitrogen evaporated from liquid nitrogen to preserve biological samples for a long time. This preservation method does not come into direct contact with liquid nitrogen and can avoid the risk of sample cross-contamination. In the liquid phase, the sample is completely immersed in liquid nitrogen at -196�°C and in direct contact with liquid nitrogen. Two modes can be selected according to different sample requirements. The advantage of gas phase tanks is that they are easy to use and operate, while the disadvantage is that they are more expensive to maintain. Although the storage modes of the two are different, they also have their own merits. When choosing, you can choose a liquid phase or gas phase liquid nitrogen tank based on your own needs.

Currently, the methods of cell preservation are refrigerator and liquid nitrogen. When it comes to long-term storage, liquid nitrogen wins. However, conventional liquid nitrogen tanks need to constantly detect the liquid level, and the cells cannot be stored higher than the liquid nitrogen level, which is not conducive to long-term storage of cells. However, the "stem cell liquid nitrogen tank" that breaks the rules can do it! For long-term storage of large quantities of dry cell samples, it is ideal to use stem cell liquid nitrogen tanks by default. Why? 1. Storage temperature is -150~-196â?? For cells, the more comfortable storage temperature is -150â??~-196â??. Conventional liquid nitrogen tanks only have a temperature option of -196â??. Samples at this temperature are not in danger. The storage temperature of stem cell liquid nitrogen tanks changes with the sample area. The temperature difference in each storage area is 10�°C, which provides more options for cells. You can choose a more suitable temperature for cells to store. 2. Prevent pollution Another important point in cell cryopreservation, stable storage time and how to prevent contamination during storage. To stabilize the storage time, the stem cell liquid nitrogen tank adopts the characteristics of vacuum multi-layer insulation, electronic temperature control and liquid nitrogen dispersion, making the storage tank intelligent cooling and constant temperature process uniform and stable. To prevent storage contamination, you must know that cells become contaminated because they are in direct contact with liquid nitrogen. First, because the cryopreservation tube is not well sealed, liquid nitrogen enters through the gap. After taking out the test tube, there is a temperature difference and pressure difference between the inside and outside. Under the combined action of temperature and pressure, the tube explodes. Second, bacteria will enter the liquid nitrogen tank after it has been used for a period of time. These bacteria are likely to flow into the freezing tube with the liquid nitrogen and contaminate the sample. Stem cell liquid nitrogen tanks can prevent contamination because they can store liquid nitrogen and cells separately, avoiding direct contact between the two. At the same time, they can also use the low-temperature environment formed by the evaporation of liquid nitrogen for storage to avoid pipe explosions and cross-contamination. risk.
