SHZ-DIII circulating water vacuum pumpIt mainly provides vacuum conditions for processes such as evaporation, distillation, crystallization, drying, sublimation, filtration and depressurization, and degassing. Specially suitable for laboratories and small-scale experiments in major universities, research institutes, chemical, pharmaceutical, biochemical, food, pesticide, agricultural engineering, biotechnology and other industries. It saves more water resources than traditional vacuum pumps, and its specially designed fluid muffler can reduce gas in water, making the vacuum degree higher and more stable, reducing gas friction, and thus reducing noise generation.
SHZ-DIII circulating water vacuum pumpstructural composition
The SHZ-DIII circulating water vacuum pump is a multi-purpose vacuum pump based on the characteristics of a small laboratory area and referring to the Japanese desktop pump. It has a one-time molded shell and is improved by reducing the volume. It has the characteristics of small volume, light weight, and beautiful appearance. It has dual meters, dual heads, four meters and four taps, and is the same on both sides. Even with the teacher's intuitive demonstration, students can turn on and off the pump on either side.
SHZ-DIII circulating water vacuum pumpAdopting dual taps, it can be used separately or in parallel with two vacuum gauges installed. The host is manufactured in two models: stainless steel movement and anti-corrosion material movement. Corrosion resistant, pollution-free, low noise, easy to move, and can also be equipped with vacuum regulating valves according to user needs. Four students can conduct chemistry experiments simultaneously, reducing the experimental space.
SHZ-DIII circulating water vacuum pumpIt contains an appropriate amount of water as the working fluid. When the impeller rotates clockwise as shown in the figure, water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness determined by the shape of the pump chamber. The inner surface of the lower part of the water ring is exactly tangent to the impeller hub, and the inner surface of the upper part of the water ring is exactly at the top of the blade (in fact, the blade has a certain insertion depth inside the water ring). At this point, a crescent shaped space is formed between the impeller hub and the water ring, and this space is further divided into several small chambers equal to the number of blades by the impeller. If the lower zero of the impeller is taken as the starting point, then when the impeller rotates 180 degrees before, the small chamber area increases from small to large and is connected to the suction port on the end face. At this time, gas is sucked in, and when the suction is completed, the small chamber is isolated from the suction port; When the impeller continues to rotate, the small chamber becomes smaller, compressing the gas; When the small chamber is connected to the exhaust port, the gas is discharged outside the pump.
