Reciprocating pump working principle and characteristics

Reciprocating pump working principle and characteristics of the piston as an example to illustrate reciprocating pump working principle. Piston pump mainly by the piston in the pump cylinder reciprocating motion to inhale and remove the liquid. When the piston starts to move to the right from the extreme left end position, the volume of the working chamber gradually expands and the pressure in the chamber decreases. The fluid opens the suction valve and enters the space left by the piston until the piston moves to the extreme right end. The water absorption process. When the piston moves from the right end to the left end, the fluid filled with the pump is squeezed, the water suction valve is closed, and the pressure valve is opened and discharged. This process is called as the pressure-pumping process of the pump. Pistons continue reciprocating motion, the pump suction and water pressure on the continuous process of alternating. This pump features: Pump pressure can be infinitely high, the flow has nothing to do with the pressure, with self-absorption capacity, flow uneven. This pump is suitable for small flow, high pressure infusion system.

LED Outdoor Light

LED outdoor lighting provides aesthetic beauty and utility to architecture. It light building, pathways, walls, garden, fountain, etc. almost anything outdoors you want to illuminate. Our high quality fixtures come in variety of finishes, sizes and styles to reflect project requirement.
LED outdoor lights are either a wide voltage AC85-265V system or low voltage 12V/24V system. Of course wide voltage is very convenient for installation and use. Low voltage systems require a transformer or power supply which converts the high voltage to 12V/24V. It has advantages allowing the lighting fixtures to be smaller in size and is safer round people and pets.
Our LED outdoor lighting technology and quality control system will bring the outdoor illumination solution perfectly and make the project more economical in its operation.
LED outdoor lighting cover kinds of category, there are LED Flood Light, street light, high bay light, wall washer light, underground light, underwater light, spike light, wall light, step light, digital tube light, point light, strip light and other decoration lighting.
We are manufacturer, not only product we care, but also lighting solution. You will get suitable advice.
