1. The role of sf6 gas density meter and density relay The so-called density refers to the mass per unit volume of a specific substance under specific conditions. The SF6 pressure gas in the SF6 circuit breaker is sealed in a fixed container. It has a certain density value under the rated pressure at 20℃. Within the range of various allowable conditions for the operation of the circuit breaker, although the pressure of SF6 gas changes with temperature, the density value of SF6 gas is always the same. Because the insulation and arc extinguishing performance of SF6 circuit breakers depends to a large extent on the purity and density of SF6 gas, the detection and density monitoring of SF6 gas purity is particularly important. If an ordinary pressure gauge is used to monitor the leakage of SF6 gas, it will be difficult to distinguish whether the pressure change of SF6 gas is caused by the actual leakage or the change of the ambient temperature. In order to achieve the purpose of frequent monitoring of density, SF6 circuit breakers should be equipped with SF6 gas density meters or density relays. The SF6 gas density gauge meter is for monitoring, and the density relay is for control and protection.

Taurine, also known as β-amino ethanesulfonic acid, is the first separation from the bezoar, so named. Taurine powder is pure white crystal powder with more than 98% purity. It is insoluble in ether and other organic solvents, is a sulfur-containing non-protein amino acids, in the body to the free state, do not participate in the body protein Biosynthesis.

B12 can promote the growth and development of poultry and livestock, especially young poultry and livestock, and improve the utilization rate of feed protein, so it can be used as feed additives.

Vitamin K can be divided into two categories, one is fat-soluble vitamins, namely vitamin K1 extracted from green plants (such as alfalfa, spinach and other green leafy plants, etc.) and vitamin K2 extracted from microorganisms, human intestinal bacteria (such as Escherichia coli) can also synthesize vitamin K2. Vitamin K1 is a yellow oily substance and K2 is a light yellow crystal. Both have heat resistance, but are easily damaged by ultraviolet radiation, so they should be stored away from light. The other type is water-soluble vitamins, which are artificially synthesized, namely vitamin K3 and K4. The most important are vitamins K1 and K2.

Vitamin D3 is a fatsoluble vitamin, is used as a precursor for calcium, phosphorus metabolic hormones, it has close relationship with sunshine, so also called the "sunshine vitamin". Vitamin D3 is fat soluble, insoluble in water, can dissolve in fat or fat solvents, high temperature and oxidation in neutral and alkaline solution.

Advantages of CNC EDM Spark Erosion Machine 1: The CNC spark erosion machine has designed two side repair programs, the rectangular with sharp edges and corners adopts the flat-bottomed square side repair plan, and the round or multi-curved ellipse adopts the flat-bottomed round side repair plan. During the side repair process, the electrode moves and feeds towards the workpiece at an angle. At this time, the tool electrode moves from the center to the outside, from top to bottom, and is automatically controlled by CNC, that is, the three-axis linkage. This kind of movement accomplished by CNC EDM spark erosion services machine is not easy to accumulate carbon, easy to remove chips and exhaust, will not cause arcing, and has high production efficiency. 2: CNC spark erosion machine X-axis lateral processing of opposite molds, high mold clamping accuracy, and productivity can be much higher than that of Z-axis downward processing. 3: CNC EDM spark erosion machine adds special control to the control circuit. When arcing or false short circuit occurs, the pulse power is immediately cut off, and the energy supply to the cavity is stopped. The electrode temperature will not continue to rise, reducing the occurrence of fire. 4: CNC EDM spark erosion machine adopts a complete low-voltage pulse method after high-voltage breakdown. The pulse width is equal. Practice of EDM machine application has proved that this pulse method further reduces the loss of the tool electrode, the processing surface is rough and uniform, and the end surface loss of the tool electrode is small . 5: The CNC EDM spark erosion machines by DMNC-EDM, a reliable EDM machine supplier, can use one electrode for rough and fine machining, which saves the manufacturing time and cost of the double electrode, saves the trouble caused by the correction of the fine machining electrode, and shortens the mold manufacturing time. 6: Self-appropriate function, the so-called self-appropriate knife lift, is that

cp brass angle valve is an angle stop valve. Angle valve is similar to spherical valve. Its structure and characteristics are modified by spherical valve. This is because the pipe forms a 90 degree corner shape at the angle valve, so it is called angle valve, angle valve and angle water valve. Jintian as an established and reliable angle valve supplier, provides high-quality solutions for your diverse needs.
