The gear pump is equipped with a pair of slewing gears in the pump body, one active and one passive, and the two working parts in the pump are divided into two separate parts by the mutual engagement of the two gears.
The gear oil pump is equipped with a pair of slewing gears in the pump body, one active and one passive, and the two working parts in the pump are divided into two separate parts by the mutual engagement of the two gears. A is the suction chamber and B is the discharge chamber. When the gear oil pump is running, the driving gear drives the driven gear to rotate. When the gear is engaged to disengage, a partial vacuum is formed on the suction side (A), and the liquid is sucked. The sucked liquid fills the respective valleys of the gear and is brought to the discharge side (B). When the gear enters the mesh, the liquid is squeezed out to form a high-pressure liquid and exit the pump through the pump discharge port.
Gear pump features:
1. Compact structure, easy to use and maintain.
2. Has good self-priming, so there is no need to inject liquid before each pump is turned on.
3. The lubrication of the gear pump is automatically achieved by the liquid to be delivered, so there is no need to add lubricating oil for daily work.
Gear pumps are widely used in petroleum, chemical, marine, electric power, grain and oil, food, medical, building materials, metallurgical and national defense research. The gear pump is suitable for conveying lubricating oils without solid particles and fibers, non-corrosive, temperature not higher than 150 ° C, viscosity 5 to 1500 cst or other liquids similar in lubricating oil. Try all kinds of occasions where outdoor installation and process in the coagulation and alpine regions require heat preservation at room temperature.
LED to shoot the light, English name is LED spotlights, it is the most popular energy conservation and environmental protection products, with more and more of lamps and lanterns made of LED as light source, one of the most acclaimed is LED to shoot the light, as compared with other LED lamps, LED lamp price is lower.LED lamp is mainly used for decoration, commercial space, lighting and building lighting, etc., with the development and progress of LED technology, the market of LED lamp performance advantage is very outstanding, high purity aluminum reflector, the beam is the most accurate and reflective effect is best;Symmetrical light distribution systems such as narrow Angle, wide Angle and asymmetric etc., and the projector lamp is equipped with a scale plate, people can adjust the radiation Angle conveniently according to the scale.In addition, in order to facilitate maintenance, the LED projector lamp is replaced by a back-up switch.The lighting decoration effect is first-rate, and the LED projection lamp can realize the dynamic effects of gradual change, jumping, color flashing, random flashing, gradual change, chase and scanning.
1. LED spotlights can be driven by low-voltage direct current: it has the advantages of small load and weak interference, and has low requirements on the use environment.2. LED spotlights can control the composition of the luminous spectrum well, so that they can be well used for local or key lighting in museums and exhibition halls.
3. The luminous directivity of LED spotlights is very strong: the luminance attenuation is much lower than that of traditional light sources, and the price of LED spotlights is fairly civilian.
4. The response time of LED spotlights is very fast: at the microsecond level, as long as the switch is on, it will be on immediately without any delay or flicker.
5. The light energy concentration of LED spotlights is very high: it is concentrated in a small wavelength window with high purity.
6. The service life is very long, generally between 50,000 and 100,000 hours, because LED is a semiconductor device, and even frequent switching will not affect the service life.
7. Good environmental protection, LED to shoot the light in the process of production don't add "mercury", also do not need air, do not need glass shell, good impact resistance, good shock resistance, invulnerability to breakage and facilitate transportation, very green, known as "green energy", the LED lamp price.
8. Energy saving, the spectrum of LED spotlights is almost all concentrated in the visible light frequency band, and its luminous efficiency can reach 80 ~ 90%.It is generally believed that the energy-saving of energy-saving lamps 4/5 is a great innovation, but LED spotlights are more than 1/2 energy efficient than energy-saving lamps, which is a greater reform of solid light sources.
