1. The pressure of the single screw pump is determined: the large output pressure of the single screw pump is determined according to the number of bushing stages, that is, the number of leads of the bushing:
Level 1 : Zui high working pressure is 0.6 MPa ;
Level 2 : Zui high working pressure is 1.2 MPa ;
Level 4 : Zui high working pressure is 2.4 MPa ; Due to different conveying media conditions, please refer to Table 1 for the number of bushing stages for media with severe wear.
3. Single screw pump bushing rubber material selection: Water ring vacuum pump single screw pump bushing is a rubber product, which is also a wearing part of single screw pump. Its choice is good or bad, which directly affects the life of the bushing. In the case of bushings, the life of the bushing is 3-6 months. If improperly selected, the bushing may fall off the steel pipe or the rubber may fall off. So the pump asks us to understand the basic properties of rubber and the adaptability of rubber to various media.
4. Material combination selection: To transport media of different properties, different material combinations are required.
5. Performance table: The performance table or characteristic curve of the general single screw pump is the data when the water of the 2 hand pump is used as the medium (viscosity is 1cst ), and the flow rate and the shaft power are different for conveying different viscosity. 6. Shaft seal: According to the needs and transport medium, mechanical seal and packing seal can be used, and the two structures are interchangeable. Vortex pump 7. Pump drive mode: Since the single-screw pump is a low-speed pump, the pump has many drive modes, generally low-speed motor direct connection ( 6 -level, 8 -stage), gear reduction motor drive, stepless variable speed motor drive, etc. .
The pharmaceutical industry is divided into three categories: natural extraction, biosynthesis and chemical synthesis. Pharmaceutical Intermediate is a fine chemical product in the production process from pharmaceutical chemical raw materials to raw materials or drugs. The synthesis of chemical drugs depends on high quality Pharmaceutical Intermediates. In short, pharmaceutical intermediates refer to semi-finished products or important raw materials for the production of drugs. Pharmaceutical intermediates are also an indispensable part of supporting the pharmaceutical industry. At present, there are about hundreds of pharmaceutical intermediates products, and they are constantly evolving from the old to the new, forming a large number of sub-molecular industries in the pharmaceutical intermediates industry, mainly including: cephalosporin intermediates, amino acid protectants, vitamin intermediates, quinolones intermediates, and other types of intermediates, such as medical disinfectant intermediates Antiepileptic drugs intermediates, fluorine-containing pyridine intermediates, steroid medicine intermediates and so on. The production of synthetic drugs and the research and development of new varieties are inseparable from the production and development of pharmaceutical intermediates. At present, the main pharmaceutical intermediates used in the production of drugs by chemical synthesis methods are vermicular and its derivatives, morphine and its derivatives, street and mushroom compounds, and used in the production of lactamides and cephalosporins antibiotics.
