In the case of 600 revolutions, peristaltic pumps work continuously for 24 hours, the life of the domestic silicone tube is 200 hours, the life of the imported peristaltic pump tube can reach 2000 hours. If the peristaltic pump at 100 rpm, peristaltic pump 24 hours of continuous work, the life of domestic silicone tube is 1200 hours, the life of the imported peristaltic pump tube is 12,000 hours, if not 24 hours of continuous work, intermittent work will greatly improve the life of the peristaltic pump tube.
In addition, the peristaltic pump pump head roller and the arc between the pressure tube gap, the hose life also has an impact, because the breakage of the hose is mainly manifested as fatigue breakage, the pressure tube gap is small, the pump head of the hose of the extent of the squeeze is also the greater, the hose is also the more likely to fatigue breakage, and of course, the pump head of the export pressure is also the greater. Peristaltic pump hose life factors in addition to the size of the pressure tube gap, but also consider the uniformity of the pressure tube gap. For example, whether the curve of the arc is uniform, the size of the processing error of the roller and the roller center and the center of the arc of the assembly error.
Expanding knowledge
Knowledge point one,Peristaltic pumps how to carry out maintenance
Peristaltic pumps because of its low maintenance costs. Use a long time, the machine can be customized according to the needs of the work, by a lot of liquid transfer needs of the industry welcome, then the peristaltic pump in the maintenance of what you need to pay attention to, the following for you to share:
1, peristaltic pump do not easily add grease
I believe that many of my friends in the understanding of peristaltic pumps, but also looked at the other peristaltic pump maintenance information, which has a requirement to Add grease this item, in fact, this is not accurate, should be to consult the purchased peristaltic pump manufacturers, whether or not you can add, not standardized grease maintenance instead of damage to the life of the rollers and pumping tubes, and will even have an impact on the transmission of fluid, such as the occurrence of running tubes, the transmission of fluid inaccuracy and so on.
2, stop using the maintenance
Because the working principle of the peristaltic pump, is through the roller on the hose extrusion, so that the hose cavity to form a negative pressure, and then further absorb the fluid, so the cycle of fluid transfer, so if a long period of time does not apply to the peristaltic pump, it is recommended that the upper pressure block is loosened, so that you can extend the life of the hose.
3, a reasonable choice of speed
In the case of meeting their own flow transmission, the selection of the appropriate pump head and hose, so that the operating speed is reduced, which can also extend the service life of the hose.
4, pump head and drive maintenance
Transmission process fluid only contact with the hose, so the drive and pump head are generally maintenance-free, as long as the daily use of good drying and cleaning work can be.
Knowledge point two,Screw pumps are mainly used in what occasions
1, screw pumps because of its variable delivery, self-priming ability, can be reversed, and can transport solid particles of liquid, etc., in the wastewater treatment plant, the screw pumps are widely used in the transfer of water, wet sludge and flocculant liquid.
2, screw pumps due to the structure and working characteristics, can transport high solid content of the media, flow uniformity, pressure stability, low speed is more obvious, due to good variable adjustability, and thus can be a pump for multiple purposes, transporting different viscosity of the media.
3, the installation position of the screw pump can be tilted arbitrarily, suitable for conveying sensitive goods and goods susceptible to damage by centrifugal force and so on.
Knowledge point three,Screw pump working characteristics
Screw pumps mainly have the following characteristics: simple structure, the use of safe and reliable, easy to use and maintain, the liquid continues to be an average, stable pressure, murmur and vibration of the small, with the ability of self-absorption, but the processing of the screw is more troublesome.
Knowledge point four,What is a three-screw pump
Screw pumps are a rotary volumetric pumps, according to the number of screws, which can be divided into a single-screw, twin-screw, triple-screw and multi-screw pumps, triple-screw pumps, that is. Three screw pump, is a three screw screw pump, including an inserted in the pump cylinder in the active screw and its engagement of the two slave screw, the three mutually meshing screw, in the pump cylinder according to each lead to form a sealing cavity, resulting in the suction and discharge between the mouth of the seal.
Knowledge point five,peristaltic pump uses what
Peristaltic pumps of any of the use of the scene is to deal with fluid (can be any liquid with fluidity, can also be a mixture of solid-liquid), peristaltic pumps is the main role of the transfer. Peristaltic pump conveying accuracy can reach up to ± 0.5%, so it can meet the needs of quantitative conveying, but also can meet the needs of quantitative distribution.
From the level of product function, the use of peristaltic pumps is mainly: quantitative or metered delivery, quantitative or metered distribution. So where there is quantitative conveying and distribution needs of application scenarios, can choose peristaltic pump to meet the application requirements.
Peristaltic pumps have excellent performance and reliability, so the application is very broad, to meet the application of various processes, including from experimental research, analytical instruments to industrial production in many areas, so the peristaltic pump is very useful, the use of a very wide range of the following areas:
1, analytical instrumentation: chromatography, atomic fluorescence photometer.
2, the medical industry: medical equipment and diagnostic reagents instruments.
3, biopharmaceutical: coating machine, granulation and pill-making machine, fermentation tanks, for purification, fluid transportation, distribution filling, high-precision liquid dispensing.
4, experimental research: laboratory and research equipment.
5, food and beverage: ready-to-mix beverage machine, yogurt machine, self-service vending machine, intelligent milk tea machine, seasoning distribution adding, beer industry.
6, the environmental industry: water quality analysis instruments, quality control instruments, water quality sampling instruments, smoke analyzer.
7, printing and packaging: delivery of ink and coating solvents, coatings and adhesives.
8, airbrush ink: airbrush, printer.
9, washing and cleaning: washing machine, dishwasher.
10, ceramic industry: elimination of porosity, defoamer dosing, ceramic slurry.
11, mining: transmission of abrasive ore and tailings slurry, filter feed, flocculant dosing and chemical dosing, ore sampling, pumping thickener underflow.
12, industrial applications: sand-based colloid metering, metering abrasive-containing coating solutions, metering high-viscosity resins, chemical recycling, coatings and paints.
13, pulp and paper industry: filler, pulp pretreatment in the process, pulp coating ideal for pumps, pulp and paper industry water and wastewater treatment, accurate quantitative delivery of chemicals and additives, delivery of dye additives.
