Peristaltic pump consists of three parts: drive, pump head and hose. Fluid is isolated in the pump tube, can quickly change the pump tube, fluid can be retrograde, can be dry running, low maintenance costs and other features constitute the main competitive advantage of the peristaltic pump.
Expanded knowledge
Knowledge a,Peristaltic pumps use the conditions of which
Peristaltic pumps must meet some specific Conditions to use, otherwise it may not pay off, the following share some peristaltic pump skills:
1, peristaltic pump flow size is determined by the driver, if you need a large flow rate then need to replace the structure and materials, the ordinary case of the rotational speed should not be too high to control the speed of the speed of 50 revolutions or less.
2, when there is a rated flow rate is greater than the actual, if you need to quantitative requirements, you should let the pump rated flow rate and the actual flow rate.
3, if the use of peristaltic pumps in a number of areas, the need for flow stability or adjustable speed, flow requirements need to choose to use adjustable speed pump, but also note that the flow rate should not exceed the rated flow.
4, peristaltic pump hose is the main equipment for conveying, if conveying a certain temperature of the fluid, high temperature, you need to use some special heat-resistant hose.
5, the pressure problem, when operating, the actual pressure of the system should not be greater than the rated pressure of the pump.
Knowledge point two,Screw pumps are mainly used in what occasions
1, screw pumps because of its variable conveying, self-priming ability, can be reversed, and can convey solid particles of liquid, etc., in the wastewater treatment plant, the screw pumps are widely used in conveying 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 the 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.
14, household appliances: intelligent toilet, soap dispenser, disinfectant dispenser, sweeper, mopping machine.
15, industrial machinery: mills, glass fiber spinning machine, photovoltaic production.
