1, power on no response
If the peristaltic pump is connected to the power, power on no response, then please check in the following order.
(1) If the circuit protection device is installed, make sure that the circuit is not tripped;
(2) Make sure that the power plug is inserted into a properly working outlet;
(3) Check whether the power cord is firmly plugged in;
(4) Make sure that the power interface fuse is blown.
If there is still no response after checking, you can consult the manufacturer.
2, the pump is on but can not run
Check whether the coupling is damaged, if not, please cut off the power supply, manually rotate the pump head, toggle the roller, whether the rotation is normal.
3, the pump transmits low or no flow
Prioritize whether the set flow rate is too low, for example, when setting 0.1ml, the roller is almost motionless, please set a higher flow rate when testing. Secondly, you can also follow the following steps to check:
(1) Check if the supply is normal;
(2) Check if the pipe is not tangled or blocked;
(3) Check if all the valves are open;
(4) Check if the hose is located in the middle of the rotor;
(5) Look for the hose is not cracked or damaged;
(6) Check the direction of operation;
(7) Check if the pump head rotor can rotate flexibly.
4, external control can not control
Whether it is digital display type and LCD type, can be seen in the display of the external control icon has been switched successfully, such as has been successful, you can check whether the external control line is correctly connected, the signal source is set up normally.
Expanding knowledge
Knowledge a, peristaltic pump pump head does not rotate how to
Peristaltic pump pump head stops mainly due to Mechanical seal failure caused. Mechanical seal failure is the main manifestation of leakage, leakage of the main reasons are:
1, dynamic and static ring sealing surface leakage, caused by end face unevenness, surface roughness does not meet the requirements of the use of the surface of the scratched grooves, the surface of the particulate matter, resulting in the imbalance of the two end faces, thus the phenomenon of leakage.
2, unqualified installation, compensation ring seal leakage, the main reasons are the deformation of the gland, uneven preload, installation method is not correct, does not meet the installation requirements, the quality of the seal is not qualified, deformation, will lead to leakage.
3, the sealing ring selection of large or small, will lead to leakage.
Knowledge point two,Screw pumps are mainly used in what occasions
1, screw pumps because of its variable delivery, self-priming ability, reversible, can transport solid particles of liquids and other characteristics, 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 out of the continuous average, stable pressure, murmur and vibration is small, with the ability of self-absorption, but the processing of the screw is more trouble.
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 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 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.
