What are the classifications of water pumps?

Classification of water pumps

1. According to the direction of the pump shaft, it can be divided into horizontal, vertical, and inclined

2. According to the type of shell splitting, it can be divided into radial splitting and axial splitting

3. According to the number of stages, it can be divided into single-stage and multi-stage

4. According to the suction form, it can be divided into single suction and double suction

5. According to the form of the water pump, it can be divided into various center support types, pipeline type, common seat type, split seat type, and movable

6. According to the driving mode, it can be divided into direct connection, gear transmission type, liquid coupling transmission type, and skin constant transmission multimodal type 7. According to special structures, it can be divided into submerged, cylindrical, double walled shell, pit tube, extraction, self-priming, submersible, and shielding types. 8. According to axial force balancing methods, it can be divided into balanced drum, balanced disc, self balancing, and balance hole types. 9 According to different purposes, it is mainly divided into boiler feed water pump, circulating water pump, sewage pump, impurity pump, sand pump, slurry pump, mud pump, sewage pump, clean water pump, fire pump, process pump, booster pump, corrosion-resistant pump. 10. According to different materials, it is divided into cast iron pump, stainless steel pump, plastic pump, fluoroplastic pump, engineering plastic pump. 1. According to the structural form, it is divided into centrifugal pump, diaphragm pump, gear pump, plunger pump, reciprocating pump, vacuum pump, jet pump.

2. Practical principle and operating steps of pipette. Liquid pipettes are mainly divided into two categories based on their working principles: gas piston pipettes and external piston pipettes. Air push: The working principle is to push the piston through the expansion and contraction of the spring, remove some air, use atmospheric pressure to suck in liquid, and then push the air to discharge the liquid by the piston. There is an air column between the liquid and the piston, which is suitable for conventional aqueous solutions. External piston type pipette (Positive separation): The working principle is to extract and dispense liquid through the continuous movement of the piston inside the pipette or suction head. The piston comes into direct contact with the liquid without an air column. This design is not only suitable for conventional aqueous solutions, but also particularly suitable for problematic liquids such as high viscosity, volatility, and foaming. The operation steps of a pipette include selecting the appropriate pipette tip: The pipette tip and pipette tip are equally important, and only high-quality pipette tips can fully reflect the accuracy of the pipette. It is recommended to use the manufacturers original suction head to ensure smooth and flawless tip and uniform height, thereby ensuring the reproducibility of experimental results. Choose a pipette that is suitable for the range: The optimal range for using a pipette is 30% to 100% of its maximum range. Using within this range can ensure the accuracy and precision of pipetting. Assembly of pipette tip: Insert the pipette tip vertically into the pipette tip, gently press and tighten, do not knock up and down or shake left and right to avoid damaging th
