When the circular gear pump works, the two gears, the pump body, and the front and rear covers form two closed spaces, when the gears rotate, the volume of the space on the side of the gear disengagement from small to large, forming a vacuum will be sucked into the liquid, the gear mesh side of the volume of the space from the large to small, and will be squeezed into the pipeline to liquid.
The suction chamber and discharge chamber are separated by the meshing line of two gears. The pressure at the discharge port of the gear pump depends entirely on the magnitude of the resistance at the pump outlet.
Advantages of Circular Arc Gear Pump
Circular Arc Gear Pump adopts the most advanced continuous contact gears, which can completely eliminate the involute gear transfer pump. Arc gears in the two meshing tooth profile for a point of continuous contact, will not produce trapped oil phenomenon, completely solved the involute gear pump due to trapped oil phenomenon caused by the pump vibration, noise, bearing load increase and other phenomena.
Expanding knowledge
Knowledge point one,What are the characteristics of circular gear pumps
1, circular gear pumps compact structure. so that the use of management and maintenance and repair.
2, circular gear oil pump has a good self-priming, so each time the pump is turned on before the work without filling the liquid.
3. The lubricating oil of the circular gear oil pump is reached automatically by the conveyed liquid, so there is no need to add lubricating oil during daily operation.
4, circular gear oil pump in the two meshing tooth profile is a point of continuous contact, so completely avoid the occurrence of trapped oil phenomenon, thus solving the trapped oil phenomenon caused by the pump's vibration, noise, bearing load increase and a series of problems.
Knowledge point two,Screw pumps are mainly used in what occasions
1, screw pumps because of its variable conveying, self-absorption ability, can be reversed, and can be transported with solid particles of 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 pumps are a rotary volumetric pumps, by the Screw how much, can be divided into single screw, twin screw, three screw and multi-screw pumps, three-screw pump, that is, there are three screw screw pumps, including one inserted in the pump cylinder in the active screw and its engagement with the two slave screw, three mutually meshing screw, in the pump cylinder according to each lead to form a sealing cavity, resulting in a seal between the suction and discharge ports.
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 scientific research, analytical instruments to industrial production in many fields, so the peristaltic pump is very useful, the use of a very wide range of areas:
1, analytical instruments: 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: fillers, processes in pulp pre-treatment, ideal pumps for pulp coatings, water and wastewater treatment in the pulp and paper industry, precise dosing of chemicals and additives, delivery of dyeing additives.
14, household appliances: intelligent toilet, soap dispenser, disinfectant dispenser, sweeper, mopping machine.
15, industrial machinery: mills, glass fiber spinning machine, photovoltaic production.
