Centrifugal pump classification 1. Dynamic pump Dynamic pump is through the high-speed rotating impeller or high-speed motion of the fluid energy is applied to be fed continuously to the liquid in the pump housing to increase the speed of the maximum, then, through the pump The cross-section of the flow channel in the shell changes gradually and the velocity gradually decreases, and its kinetic energy is partially converted into the pressure energy at the outlet of the pump. Power pump can be divided into blade and jet (special role in the pump) two categories. According to the flow direction of fluid in the pump housing, but also further divided into centrifugal pump, axial flow pump. 2. Positive displacement pump Positive displacement pump relies on periodic changes in the volume of several closed spaces by applying pressure to the liquid by means of squeezing to increase the pressure directly to the desired value for delivery of the liquid through the valve or orifice Go to the pipeline. According to the movement characteristics of booster components, positive displacement pumps can basically be divided into two types of reciprocating and rotor. Each category can be further subdivided into several forms. 3 Centrifugal pump classification 1). According to the method of liquid suction impeller: (1) single suction centrifugal pump: impeller suction side only one side, liquid from the side of the impeller into the impeller. (2) Double Suction Centrifugal Pump: Both sides of the impeller have suction ports, and the liquid enters the impeller from both sides. 2). According to the impeller series: (1) Single-stage pump: only one impeller. (2) Multistage Pump: Two or more impellers mounted in series on the same pump shaft. 3) According to the form of pump body: (1) Volute pump: The housing is in a spiral shape. After the liquid is thrown out of the impeller, it enters into the helical volute chamber and then into the discharge pipe, such as the Y-type pump. (2) double volute pump: impeller discharge side of the shell with double scroll chamber. (3) cartridge pump: the pump inner shell mounted in an outer cylinder double shell centrifugal pump. In addition, the pump can be divided into different media pump water pump, pump, corrosion-resistant pumps.
3D LED Bulb
3D LED Bulb is widely used in dj lighitng, disco lighting, club lighting, resturant lighting, theme resturant lighting and park decoration lighting. We call the rgb led bulb in different name for different led lighting application, like dj ball, ball 3d, disco ball light bulb, club led bulb, etc
The 3D LED Bulb can be for indoor and outdoor. We cooperate with other famous design organizations to make a big improvement on LED 3D control technology, and developed many 3D visual products, like the ball string(40mm 3D LED Ball string, 50mm 3D led ball string), and the big Magic LED Ball with different size,. The 3D balls control mainly by DMX 512 protocol, and easy to built the led lighting system.
Suppor DMX512 control, address can be manually and automatically set, long transmitting distance of signal and strong anti-interference.
3D LED Bulb Built-in high precision constant current driver IC, LED luminous efficiency is good and uniform color.
Apply superior quality high brightness SMD5050 led, red, green, blue, white and other colors can be chosen.
Apply more efficient DC to DC power supply manage disign, energy saving can reach 40%.
Adopt environmentally friendly materials, no glare, no noisy. Solid capacitor design, lifespan is longer.
Potting glue craft, waterproof level is superior, and can reach IP65.
