(a) the advantages of the peristaltic pump
1, no pollution: the fluid only touches the pump tube, does not touch the pump body;
2, high precision: can produce up to 98% of the vacuum, high stability and accuracy;
3, low shear: is the transport of shear-sensitive, erosive fluids ideal tool;
4, good sealing: no valves, mechanical seals and packing sealing device, there is no such factors that produce leakage and maintenance, has a good self-priming ability, can be idling, can prevent backflow;
5, peristaltic pump maintenance is simple: no valves and seals, the hose is a wearing parts;
6, can be pumped liquids, gases, solids, or multi-phase mixtures. Easy to transport solid, liquid or gas-liquid mixed-phase fluids, allowing the diameter of solids contained within the fluid to reach 40% of the inner diameter of the tubular components, can transport a variety of abrasive, corrosive, oxygen-sensitive properties of the material and a variety of food products, etc., only the hose for the need to replace the parts, the replacement operation is extremely simple; in addition to the hose, the transported products do not come into contact with any parts.
(B) the shortcomings of the peristaltic pump
1, the peristaltic pump will produce pulses;
2, the peristaltic pump tube is easy to damage;
3, peristaltic pumps are unable to achieve too high a pressure.
What is a peristaltic pump
Peristaltic pump (PeristalticPump), also known as the hose pump, is a new type of industrial pumps, it is a product of modern industrial development, widely used in pharmaceutical, food, chemical and other industries, transport some with sensitive, viscous, strong corrosive, with grinding effect It is widely used in pharmaceutical, food, chemical and other industries to convey sensitive, viscous, corrosive, abrasive, high purity and granular materials.
Expanding knowledge
Knowledge a ,Hose pumps and peristaltic pumps what is the difference
Hose pumps and peristaltic pumps there is no strict distinction between them. Peristaltic pump is named for its working principle, hose pump also belongs to the category of peristaltic pump. Generally speaking, peristaltic pump refers to small flow, low outlet pressure, mostly used in the field of health and laboratory measurement. The hose pump refers to large flow, high output pressure, mostly used in industrial settings for high-flow transportation and metering.
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, can be transported with solid particles of the liquid and other characteristics, in the wastewater treatment plant, the screw pumps 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 the three screw pump
Screw pump is a rotary displacement pump, according to the number of screws, can be divided into single-screw, twin-screw, triple-screw and multi-screw pumps, the three-screw pumps, that is, the three screw pump. 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 scientific 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: chromatograph, 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.
14, household appliances: intelligent toilet, soap dispenser, disinfectant dispenser, sweeper, mopping machine.
15, industrial machinery: mills, glass fiber spinning machine, photovoltaic production.
