Roots vacuum pump purchase
We should all be familiar with roots vacuum pump. As an industrial equipment is widely used at present, we need to pay more attention to the use of the equipment to ensure better effect. In addition to the inspection of the manufacturer, there are other aspects that we need to consider in the purchase process. Let’s introduce them to you.
1. First of all, it should be clear about the layout of the device, topography, water level conditions, operation, economic scheme comparison and other aspects of the actual situation.
2. Consider the type of Roots vacuum pump, horizontal, vertical or other types.
3. According to the nature of liquid medium, clean water pump, hot water pump return pump, chemical pump or corrosion-resistant pump or impurity pump shall be determined, or non blocking pump shall be adopted. If the pump is installed in the explosion area, the explosion-proof motor shall be used according to the explosion area level.
4. Considering the amount of vibration, it is divided into: pneumatic, electric (electric divided into 220V voltage and 380V voltage).
5. Consider the flow size, choose single suction pump or double suction pump.
6. According to the height of lift, single-stage pump or multi-stage pump, high-speed pump or low-speed pump (air conditioning pump) and multi-stage pump have lower efficiency than single-stage pump. When single-stage pump and multi-stage pump are both available, single-stage pump should be selected.
7. The specific model of Roots vacuum pump shall be selected. After the selection of any series of pumps, the specific model can be determined on the type spectrum or series characteristic curve according to the two main performance parameters, i.e. the flow rate, the head after enlarging 5% – 10% margin.
Through the above introduction, we can learn that when purchasing roots vacuum pump, there are still many aspects to be considered. Not only the use environment should be considered, but also the different models of the equipment should be understood. Only choosing the equipment with suitable model can play a good use effect, so we should do more consideration in the purchase work.
