1, why should fully understand the media situation?
Different media, PH value is different, corrosive different. According to the chemical performance control select the appropriate hose and nozzle plug.
2, why the hose peristaltic pump has intermittent operation and continuous operation of the points?
Continuous operation of the rubber hose will accelerate fatigue, running time to help us understand the hose life or have a chance to choose a smaller pump
Intermittent operation and continuous operation how to define?
Run for more than an hour an hour is intermittent operation.
Running one hour or less for one hour or less belongs to continuous operation.
3, why do you want to understand the medium temperature?
Operating at high temperatures accelerates hose fatigue and aging. As the temperature increases, the hose pump speed to reduce.
Hoses of different materials, the temperature limits are as follows:
Natural rubber hose (NR): 80 ℃
EPDM hose (EPDM): 100 ℃
Nitrile rubber hose including food grade (NBR): 80 ℃
Shanghai Pine rubber hose (HYM): 80 ℃
4, hose pump flow depends on what it?
a) Tube lumen capacity
b) Pump rotation speed
c) Operating environment There is a great limit to the self-priming capacity of the pump
Of course, the same flow we can choose the pump there are several so we have to consider some of the user's factors: the initial investment and long-term operating costs of the relationship between
5, why the pressure and flow exactly match the actual situation of the customer?
Flow rate can set the pump rotation speed, according to customer needs to set the pump pressure (maximum 16Bar). Select the pump type, determine the net power, installed power.
6, the length of the inlet pipe and outlet pipe length, the viscosity of the liquid is how much? What is the role of this information?
Decided to drive and friction loss
Determine the friction loss
Do you need an auxiliary vacuum unit?
7, what kind of material needs the nozzle connector?
Sanitary grade 316 stainless steel is commonly used and PP and PVDF are also available.
Flange standard DN16, ANSI, JIS.
