1, often add grease, electric drum pump for high-speed operation, grease is easy to volatilize, it must make the bearing at the lubrication can keep clean, and pay attention to add change.
2, pay attention to the preservation of electric pump should be placed in a dry, clean and no corrosive gas environment.
3, gear pumps often check and repair, electric drum pumps should be frequently checked and repaired, must check the power cord: internal wiring, plugs, switches are good, whether the insulation resistance is normal, commutator and brushes are in good contact with the armature winding level expansion of the stator windings is a moderate disconnection phenomenon, bearings and rotating parts of the damage and so on.
4, gear pumps pay attention to the insulation resistance, long-term shelved or in a humid environment of the electric pumping pump, must be used before the use of 500-volt megohmmeter to measure the insulation resistance of the windings. If the insulation resistance between the winding and the motor shell is less than 7 megohms, the winding must be dried.
5, save every part and exchange the same parts, in the disassembly and inspection of gear pumps, should save every part, pay special attention to the explosion-proof parts of the explosion-proof surface can not be made to damage the hair, including insulating gaskets and casing, such as damage, it is necessary to exchange the same parts on a new one, shall not be used less than the performance of the raw materials used as a substitute for the material, or the original specifications of the parts do not match the assembly of all the parts should be installed according to the original position, can not be omitted. The assembly should be all the parts in the original position installed, can not be missed.
Expanding knowledge
Knowledge a, Micro Gear Pump how to clean
1, all kinds of parts immersed in sodium hydroxide or sodium sulfate degreasing strong. Sodium sulfate and other degreasing solution for a period of time (up to 48h) after the oil and dirt loose, and then carefully cleaned with a variety of scrubbing things, cleaning is complete, with warm water to flush once.
2, will be a variety of loose parts in the acidic cleaning agent (ratio of 20% ~ 30 "hydrochloric acid") soaked in 30 ~ 40min, and then carefully cleaned with a variety of scrubbing things, and finally rinsed with warm water.
3, the bulk of the alkaline cleaning agent (ratio of 10% sodium hydroxide) in the impregnation of 15min (cleaning agent temperature of 30 a 40 ℃), and then with the scrubbing things to clean, and then rinse with warm water once.
4, the bulk of the dry, coated with rust inhibitor or immediately put into the installation, not installed in the short term when the use of plastic film cover.
5, the hose is the most difficult to clean the components, can be sprayed with high-speed liquid flow. Hard tube can also be used in the same way to clean, in order to solve the water-based cleaning of rust, the use of anti-rust oil (such as SM-I anti-rust oil), the parts cleaned and immersed in this water film replacement type of anti-rust oil, water in the parts immediately be removed, together with a layer of rust on the surface of the workpiece to generate a layer of anti-rust oil film, the metal may not be subjected to corrosion.
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 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 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 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: 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.
