Description
Technical field
The utility model relates to the impeller unit of water circulating pump, relates in particular to the impeller of pump device that a kind of energy-conservation machinable regulates.
Background technology
In recent years, along with enterprise become more meticulous operation raising, in the water drainage-supply system of enterprise, water circulating pump power consumption accounts for the 70-80% of the total power consumption cost of circulating pump room, blower fan of cooling tower and other equipment account for the 20-30 of total power consumption cost; When device design, often from security standpoint, strengthen water circulating pump flow, improve recirculated water to pump lift, so that increase the capacity motor of water pump, thereby strengthen the power consumption of water circulating pump; In order to reach energy-saving and cost-reducing, reduce the object of device operating cost, in actual motion, conventionally adopt the way of current limliting: (1) turns down water circulating pump outlet valve and reduces the system supply circulating cooling water yield, but the method energy-saving effect is limited, and after controlled circulation exit of pump valve opening, pump outlet pressure increases, the outer turbulent flow of current limliting is obvious, pipe flushing is heavier, and pipeline loss in head is large, causes energy waste; (2) adopt the operation method of frequency control to regulate circulating water flow, but because frequency conversion equipment investment is larger, determined that RHVC is not the best approach that reduces pump energy consumption; In production reality, because technical merit limits or lacks necessary means of testing, leave larger affluence amount while design, pump head exceeds system actual resistance (more than exceeding 20m at most) mostly, has increased energy consumption in addition; Only have and allow recirculated water pump lift approach with system running resistance value under the prerequisite that ensures necessary circular flow, just can reach the object that reduces pump energy consumption; For existing issue, a kind of external diameter that changes water circulating pump blade is provided, adjust pump operating point, flow, lift and function all change, and reach and reduce pump energy consumption object.
Utility model content
The many advantages of storage such as the utility model object is the impeller of pump device that a kind of energy-conservation machinable that provides in order to overcome the deficiencies in the prior art regulates, and energy-saving effect is obvious, simple and direct, reliable, cost-saving.
For achieving the above object, the technical solution adopted in the utility model is: the impeller of pump device that a kind of energy-conservation machinable regulates, comprise wheel hub, and described wheel hub equal intervals is provided with multiple reinforcements, described reinforcement is provided with blade, and described blade is connected by puller bolt with described reinforcement; Described reinforcement is provided with the cavity volume matching with the bottom of described blade in upper end; In described blade bottom, be provided with and blade elongated slot in the same way, the position that the madial wall of described elongated slot is corresponding with elongated slot is provided with screwed hole one, and described screwed hole one communicates with elongated slot; The madial wall of described cavity volume is provided with the screwed hole two isometrical with screwed hole one.
Further improved as the utility model, described reinforcement is four.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages: the impeller of pump device that a kind of energy-conservation machinable of the utility model scheme regulates, ensureing under safe, the stable prerequisite of process operation, improve by blade construction, a kind of machinable adjusting vane radical length is provided, the operating point of effectively adjusting water circulating pump, changes characteristic curve of pump, has changed flow, lift and the power of water circulating pump; Energy-saving effect is obvious, has the many advantages of storage such as easy, quick, reliable, cost-saving.
