Circulating water vacuum pump structure and structural characteristics

Circulating water vacuum pump uses circulating water as the working fluid, it uses the principle of negative pressure jet to design a new type of multi-purpose vacuum pump equipment, nowadays these products are widely used in evaporation, distillation, crystallization , Filtration, decompression, sublimation and other operations, universities, pharmaceutical and chemical industry, food processing and other fields. However, people know very little about the circulating water vacuum pump, for those who are ready to use or have begun to use the user, we must be circulating water pump structure and structural characteristics have a full understanding. Circulating water vacuum pump structure and structural features 1, circulating water vacuum pump installed two suction nozzle, alone or at the same time exhaust operation. Each suction mouth each equipped with a vacuum gauge, you can easily observe the degree of vacuum, the exhaust pipe is equipped with a check valve to prevent the vacuum operation unexpected shutdown, the circulating water back to the vacuum equipment to go. 2, circulating water pump components pump stainless steel, from acid-base and other corrosive effects; at the same time does not produce any pollution of the oil, impurities and other laboratories. 3, the box uses a newly developed transparent water tank to meet the organic dissolved coal (acetone, ether, chloroform) dissolution and corrosion damage. 4, circulating water pump head directly immersed in water, the whole lower height, small size, light weight, easy to move, can be placed on the workbench, easy to operate observation, tank cover for live installation, can be opened for easy water And overhaul. For most users, the structure and characteristics of circulating water vacuum pump must be the best way to understand circulating water vacuum pump, circulating water vacuum pump structure has largely affected the characteristics of circulating water vacuum pump, I believe with the circulating water Further development of the vacuum pump, circulating water vacuum pump structure and structural characteristics will be toward the needs of the market development.

Safety nets are protective nets installed under or on the side of high-altitude building construction equipment installation or technical performance to prevent accidents caused by falling people or objects. The safety net consists of a net body, side ropes, tethers and tendons. The mesh body is braided with net rope and has diamond or square mesh. Mesh size refers to the distance between two knots adjacent to the knit. The net ropes on the edges around the net body are called side ropes. The size of the safety net (nominal size) is determined by the size of the side rope; the rope that secures the safety net to the support is called a tether. In addition, any rope used to increase the strength of a safety net is collectively referred to as a tendon.

In addition, any rope used to increase the strength of a safety net is collectively referred to as a tendon. The safety net material requires small specific gravity, high strength, good abrasion resistance, large elongation and strong durability. In addition, it should have a certain weather resistance, and its strength does not decrease too much after being wet and wet. Safety nets use chemical fibers as the main material. All net ropes on the same safety net must use the same material, and the wet-dry strength ratio of all materials must not be less than 75%. Generally, synthetic chemical fibers such as vinylon and nylon are mostly used as net ropes. Polypropylene is forbidden due to its unstable performance. In addition, as long as it meets the requirements of relevant international regulations, cotton, linen, palm and other plant materials can also be used as raw materials. No matter what material is used, the weight of each safety flat net should generally not exceed 15kg, and it must be able to withstand 800N impact.
