Single-stage pump selection

[Asia Fluid Network News] Single-stage pump installed in accordance with the motor is divided into: horizontal single-stage pump, vertical single-stage pump. According to the inhalation of the runner can be divided into: single-stage single-suction centrifugal pump, single-stage double-suction centrifugal pump. Different needs in the choice of products need to focus on the different points in the single-stage pump selection requires more attention. The following is a brief introduction of some of the more commonly concerned about the place. Single-stage pump 1, according to the layout of the device, topography, water conditions, operating conditions, economic programs and many other factors; 2, requires a large area; vertical pump; 3, easy to manage, but bulky, More expensive; 4, to facilitate automatic 盍 or remote control, and compact; 5, in many cases the impeller submerged in water; 6, any time you can start; 7, the installation area is small, the price is cheaper; Type and other types (pipe type, right angle type, variable angle type, corner type, parallel type, vertical type, vertical type, submersible type, disassembled type, liquid type, Oil, water temperature). Horizontal pump disassembly and assembly convenience; on the basis of use to choose, mainly consider the flow, water lift, suction lift, the installation environment. This is also the place where special attention is required when selecting. A class of products if you want to remain competitive in the long run, need to do a lot of work; For consumers, a class of products is not only the quality of the product itself, but also requires consumers to understand a certain product knowledge. Only a good job, a class of products will have healthy development. Related Articles: Centrifugal Pump Parameters Centrifugal Pump Features Analysis

Metallographic Cutting Piece

It is very important to control microbial activity in cutting fluid containers. Both bacteria and fungi can cause problems because they metabolize the components of the cutting fluid, resulting in the production of biofilm/mucus (large quantities of biofilm/mucus can exacerbate foaming problems and sticky surfaces) and secondary metabolites in the form of short-chain organic acids. The latter can result in a lower pH of the cutting fluid and an increased risk of corrosion. It is also important to note that high levels of bacteria and fungi can cause health problems for those operating the machines.



If the pH drops to less than 8.5, it may indicate bacterial growth in the cutting fluid. In such cases, we recommend measuring bacterial growth and replacing the cutting fluid if the test is positive.



Other signs of bacterial growth are a bad smell and fungal/bacterial film on top of the cutting fluid.
