Following is a brief introduction of pump performance characteristics include the following :
1. And centrifugal pump (pump milk) : centrifugal pump because of its simple structure, low cost and has been widely used. Pump million compared with the following main points with distinction :
a) pump is a positive displacement pump with 10,000. transportation can be more accurate flow control variables can also be made to facilitate the pump. And the output is beyond the control of the centrifugal pump, with the decline in the increase of resistance : 10,000 with a strong self-priming pump, and the centrifugal pump to be in full operation before the liquid.
B) with the pump speed low, generally between 200rpm to 600rpm. Output has been steadily materials were delivered and its components will not be jeopardized. And high speed centrifugal pumps, the delivery of materials subject to powerful centrifugal force of the impact and role Therefore, a constant source of energy of the material delivered mixture of different ingredients, the quality of the products. And 10,000 use the pump is the best choice to solve this problem. So it is particularly applicable to transportation and even mixture of solid particles containing materials.
C) pump can be used for the transmission of high viscosity material, known as colloidal pump. And centrifugal pump could not.
D) pump can be used to facilitate the export of manufactured pressure higher species such as 1.5MPa. Quantitative suitable for long-distance transport or high resistance.
E) pump used to produce more complex precision, high cost, it is also the greatest disadvantage compared with the centrifugal pump.
2, and screw pump (MC Pump) : For the same two-volume pump Therefore, its performance is similar-can smooth high-viscosity material, have higher transportation pressure. But the greatest flaw in the decision of a screw pump in the health requirements of the non-applicability of the occasion - because of the screw-sculptured surfaces and the many resident chamber decided it will not become a health pump. wall tetrafluoroethylene or rubber materials to be delivered more likely to transfer material damage caused by pollution. And 10,000 use the pump rotor and the rotor chamber Streamline basic structure is not dead spots and non-metallic pieces. Therefore, strictly speaking in food and beverages, pharmaceutical, and other industries with high health requirements, with 10,000 more suitable pump application Especially now increasingly high degree of automation of the production line. Meanwhile more and more use of CIP-line (local) cleaning This demonstrates that the use of pump selection million importance.
Transmission : rotor pump rotor pump drive generally follows form one. Motor + 7.2 reducer : This set of simple transmission, rotor speed is constant. a decision is not adjustable flow. If you think the role of governor allocated converter can be achieved. 2. Electrical machinery friction + CVT Transmission : This depends on the speed manual adjustments to achieve its features are safe and reliable. Adjustable 0.71 level. Shortcomings in non-automatic adjustments more difficult, the operating speed the process, not a state governor in the stands. 3. Frequency Converter : + motor speed automatic adjustment can be realized in this way, is a free flow adjustments. The advantage is a higher degree of automation and easy to operate. Inverter drawback is the higher prices, smaller low-speed torque.
Application of pump rotor brief :
1. Beverage categories : dairy foods, latex, chocolate syrup, cheese wort, beer, soft drinks
2. Fruit concentrates : pudding, jam, jelly, tomato sauce
3. Paste products : fats and oils, etc.
4. : Facial cosmetics, detergents, hair gel, aromatic oils, etc.
5. Drug categories : Extract, emulsion, etc. pills Pulp
6. Chemical Industry : dye, fat solvents, and polymer resin
