JONSN barrel pump selection
Dear user, when you face a variety of pumps on the market can not choose the time, when you wander in the procurement of equipment selection, and when the time ..... you can not choose for themselves how to choose a cost-effective and suitable for their own pump? JONSN engineer summed up the following guidelines and selection guidelines, a new user reference:
First, the pump tubing selection
According to the nature of the transmission medium, the pump can be used 304 stainless steel pipe material, PP (polypropylene), Teflon (PTFE) tubing and other materials were used for different occasions, the principle of selection is as follows:
1, flammable solvent media must use 304 stainless steel tubing, tubing materials prohibited the use of PP, prone to static electricity set off the media;
2, moderate acidity corrosive media can be used PP pump tube, the outer tube material must be (PP imports Hastelloy spindle), spindle 304,316 if it is stainless steel, titanium or material will be corrosion,
3, acid alkaline media must use Teflon (Teflon) tubing material, the outer tube must be (Teflon import Hastelloy spindle), only JONSN barrel pump (Johnson Fluid Equipment) has the technology, Teflon is the top corrosion-resistant materials, has been strong acid and alkali enterprises a wide range of applications;
Other parameters such as pump pipe flow, head, viscosity, temperature, weight, length, diameter size of the production process needed to determine the specific pump.
Second, motor selection
Motor should be carefully selected, directly affect the overall performance of the pump tube can be considered from the following aspects: security, economy and practicality.
1, the installation location: indoor and outdoor heating without heating
2, the factory ambient temperature: Summer _____° C winter _____° C
3, such as the medium of low viscosity, and non-inflammable and explosive materials, can be equipped with 220V single-phase variable speed motor, use variable speed motors have the following benefits: (General Motors unsafe)
(1) speed control, flow control: the process of repackaging the media, can easily control the flow, the range of 0-160 L / min
(2) performance, stability, security worries: When the media transport of dangerous goods, you can easily control the pipe pressure to reduce accidents
(3) application of a broader, more viscous: a greater viscosity range transport, can reach 0-1500cps
(4) heat a small, live longer: to reduce noise during motor operation, fever, extend the life of the motor
4, such as low viscosity and explosive media, elections must be equipped with explosion-proof electric motor, gas supply if the factory can choose to use motor, would be more economical and some imported air motor must be selected, and have a place of origin proved very unstable domestic air motor running.
5, such as medium viscosity, high-power three-phase induction motor can be used
We will be happy to share with barrel pump selection and use of some of the experience, read carefully before selecting a pump of the above details, that will give you some help ......
