This versatile promote energy efficient water pump (energy-efficient water pump), the pump body, impeller and shaft composition, with the motor embodiment, the pump body has a self-priming centrifugal impeller chamber and the impeller chamber two impeller chamber and through the pump cover separated cavity respectively set and self-priming centrifugal impeller impeller morning gather energy, self-priming impeller and centrifugal impeller mounted on the same shaft, inlet centrifugal impeller cavity. With a self-priming pump and centrifugal dual function, just before the initial startup of centrifugal pump, the pump liquid can be filled, effort, time, easy to operate. In the power remains unchanged, its technical performance head, pump efficiency and flow relatively single pump has been greatly improved, and low power consumption, small size. The art discloses a high-pressure water pump impeller energy-saving technologies, including wheel and axle seat, the seat are uniformly distributed around the wheel spiral blade consisting of a centrifugal slinger slinger wheel, the wheel base rejection of water impeller around the front of the uniform curved composed of helical impeller blades. This technique is the front end of the existing single-slinger adds another layer of leaves curved blades or blade tips and then in an additional layer of curved blades stir the water to form an impeller blades consisting of two or three layers, Canopies forming synergies between the pump's suction lift up to 50-60m, the pump starts to reach the chiller morning gather energy options within 1-2 seconds, is a set of cooling, ventilation, dust, except Flavor is an evaporative cooling ventilation unit. In addition to allowing enterprise workshops, public places, commercial and entertainment occasions to bring fresh air and reduce the temperature, but also energy-saving, environmentally friendly! Recommended for everyone today is a new high efficiency chiller. [Features] 1, the cooling capacity: the same fin area chillers using thread brass light pipe large cooling than 1.1 to 1.5 times; 2 Morning gather energy manufacturers, frosting evenly: optimized air flow and dispensing circuits design, using the new patented liquid distributor, expansion valve with external balance dispenser mounted vertically, so obviously fin coil frosting evenly. 3, efficient defrost: electric heater spacing and its power rational design. 4 Easy installation and maintenance: the water tray and the side plates can be flexibly disassembled and cleaned.
