The different types of choice - water ring vacuum pump

water ring vacuum pumps of different sizes have different performance, so it is necessary to determine the model before use, in order to realize reasonable utilization. The following editor will show how to determine the water ring vacuum pump models.

1 kind of vacuum pump selection method, according to the equipment parameters, physical and chemical properties of transmission medium, and other parameters, according to the structure characteristics of the product and the applicable location, sure you want to choose the pump series.

2, and then determine the flow of water ring vacuum pump rating.

3, determine the rated head again.

4, and then determine the rating of the water ring vacuum pump motor.

5, check the type of the selected pump series spectrum, corresponding to the flow, the model as part of the pump head box, and then you can first determine the type of choice, often at a different speed, each can choose a model.

6, check the original selection model of the performance curve, and check whether pump NPSHr needed to meet the requirements of the equipment of NPSHa.

7, check the performance curve, to see if the rated working point of the selected models on pump efficient work area. Comprehensive comparison of water pump efficiency, speed, Low speed, longer service life) And prices to determine the final model of water ring vacuum pump.

1, selection of vacuum pump, water pump manufacturers, determine product to guarantee smooth release of all kinds of gas in the extraction process. In the process of the application of the vacuum pump, gas medium is varied, flammable and explosive, easy condensation, easy to reverse, easy corrosion and so on, the selected vacuum pump to ensure suitability. Occurring in the process of technology, for example, is water vapor, selection of vacuum pump must be able to water vapor.

2, choose limiting vacuum of main water pump, have been drawn containers must be higher than the requirements of the vacuum degree, at least one order of magnitude higher, and can work in the requirements of the vacuum degree within the scope of work.

3, pumping speed of vacuum pump than big put gas in the process. In order to ensure the vacuum degree, the choice of the vacuum pump involved in the process of continuous ventilation, the pumping speed of vacuum pump and vacuum system should be greater than the chase in the process of air volume.

4, in the choice of the vacuum pump, vacuum pump working medium and the manufacturing material should meet the technological requirements. In the application of the vacuum pump, especially in the field of medicine, chemical industry, battery, etc, to extract medium are often corrosive gas, need to adopt corresponding anti-corrosion measures equipment.

5, for the continuous production technology, chooses the vacuum pump must be reliable and meet the needs of the continuity of production. Set spare vacuum pump when necessary, automatic replacement, reduce accidents caused by production disruptions. If in the process of air to release a quantity to smaller and smaller, can set the maintenance pump to achieve energy conservation and energy conservation.

6, vacuum pump used in economy. If you have more than one vacuum pump can meet the demand of the same kind of technology, cost and operation cost are analyzed, choose economical, reliable operation, less maintenance, use and convenient maintenance of the vacuum pump.

you determine water ring vacuum pumps are the main points above models of effective measures. When you are in doubt, can undertake choosing according to the above points. After all, you choose the right model and use the correct position, so that you can compare the equipment. Good work efficiency.
