How to smoke work? Generally recognized industry standards, such as those published by the Hydraulic Society, define pumps that are energy-permutated according to the method to be imparted to a liquid: kinetic energy pumping, or positive displacement (PD) pumps. Kinetic Energy Type - A centrifugal pump delivers energy to a liquid via a centrifugal force produced by an alternative propeller, disk or other blade. The pump is made in many shapes and sizes, and both centrifugation, which is different from each other, achieves both a perceptible extent internally and externally. In spite of appearance, all centrifugal pumps use the same mechanical principle. The pumping action is obtained from a propeller driven by a bridge or magnetic coupling to a motor or some other propulsion unit, connected. The propeller is replaced (rotational cw or ccw direction) at a high rate of speed (typically 1725 or 3450 rpm) and fluid is drawn from the propeller's eye (center) to the outside of the centrifugal pusher (periphery) flow. As with the flow of the peripheral liquid from the propeller, it is guided by a volute of the shaped channel to the pump's de-livery port. All centrifugal pumps in the center of the propeller? Б Wo 褰 ?? and move it outwards between the blades. Positive displacement pump - bellows, double - diaphragm, flexible propeller, gears, vibrations, pistons, cavities, circular lobes, rotating vanes and peristaltic pumps have a liquid flow through the cylinder, gear or Promoter to promote the fixed hole. As the liquid is pushed through, it leaves a vacuum that is empty or pulled in more liquid. Metering pumps - bellows, diaphragm, peristaltic, piston, and syringe pumps are all metered into a chamber Pump pulling fluid through the insert valve, closing the insert valve, and then trying to complete the liquid Export valve. Centrifugal pump variable speed? 3. What is exactly a positive replacement pump? Which pump can I run? 6. What pumps do you carry to handle the particles? 7. I need a gentle pump action, what do you recommend? 8. When do you run maintenance on the pump? The color matching of tinplate boxes plays an important role in the sales of goods. The first impression of consumers when they see the goods comes from the Iron Box packaging. The beautiful iron box and the comfortable color matching make people feel very comfortable. From the perspective of psychology, vision accounts for 87% of the five senses; Hearing, smell, touch and taste only account for 13%. It is better to see than to hear. So, how can we choose the matching colors of tinplate boxes to attract consumers?

Pumps move liquids in a number of ways:
The most centrifugal pump does not allow variable speed motor. However, you can control the flow rate on lift using a flap.
A positive displacement pump gives a given volume of liquid for each revolution of the motor. Bellows, double - diaphragm, flexible propeller, gears, vibrations, pistons, cavities, circular lobes, rotating vanes and peristaltic pumps are all positive displacement pumps.
Peristaltic, piston due to ceramic head, bellows pumping, and diaphragm pumps for any length of time may be run dry. Centrifugal, rotating vanes and gear pumps should not be run dry; the exception is if the gear or propeller is self-made in which case the material is lubricated, like the RYTON pump can be run for a few minutes while loading the detonator.
5. What is the maximum viscosity of the pump?
This depends on the type and characteristics of the pump. Diaphragm pumps (especially double diaphragms) and gear pumps are often the best liquids to stick.
Diaphragm pumps, bellows pumps and peristaltic pumps will do well. When choosing a material, consider chemical compatibility and wearing resistance. Use a pump with larger fittings so they are not easily blocked in the same way.
A peristaltic pump, used at low speed. You can also use a diaphragm pump, once again at low speed. Centrifugal and gear pumps, working at high speeds and with high trim rates, should be avoided.
This depends on the pump and application. In general, the diaphragm of a pump is dosed with a gauge for about 6 to 12 months; the gear on the gear pump lasts for about 3 to 6 months; and the motor usually lasts for several years. DC motors require periodic brush replacement. It is important to test the brush wear; the normal brush should be replaced every 6 months.
The color matching of the iron box packaging mainly enables customers to perceive the packaging items of the iron box at a glance from the packaging color of the iron box. However, there are still many product packaging colors on the market that do not achieve this effect. For example, tea is generally packaged in green. Stimulating colors can attract customers' attention, such as bright red, and red is used for many wines and pastries. Pink and goose yellow are used to express the feeling of closeness and warmth. Therefore, food packaging generally uses this kind of color packaging.
Contrast can make colors bright, vivid, lively, both aesthetic and pleasure. For example, Japan's soup filling series low box packaging is a group of masterpieces based on consumer psychology. The author believes that although drugs are used to cure diseases, the pain of consumers in the process of treatment is intolerable, which gives rise to a psychological feeling of fear. In view of this, when designing the packaging iron box, the author used distinctive color contrast ingeniously to make people feel that this enema is different from those similar products with cold colors and mainly words, as if there is something appetizing in it that is not so terrible. In terms of color contrast, it is necessary to prevent fancy, messy, complicated, raw and hard masonry, and avoid the inharmonious atmosphere left in consumers' hearts.
The color matching of tinplate boxes is very skillful. A good color matching will help the product to be sold, otherwise, it will be different from the expected effect. Good designers have their own unique style in color matching.
