Description
Technical field
The invention belongs to industrial water pump technical field, relate generally to a kind of energy that can carry out energy recovery recycling and recycle radial suction booster.
Background technique
Along with expanding economy, the energy is significant as promoting development in science and technology and maintaining existing social plateau.But the extensive operation of the economic model of China, makes the value of the energy too low, the energy of the energy is just abandoned by as the energy that cannot recycle usually after once utilizing.Its main cause is that apparatus for energy recovery technology maturity is low and the once investment of equipment is higher, safeguard that running also needs certain expense, the not high many factors of rate of return on investment, make the enthusiasm of enterprise to withdrawal liquid dump energy low, especially energy is eliminated to the liquid energy many uses reduction valve step pressure reducing lower than 200 kilowatts/hour, be arranged on the pressure relief valve in pipeline and pipe-line equipment, between half a year to one year, just there will be loss, cause huge energy waste and fund waste.
Especially the Hydraulic pump of third quadrant hydraulic turbine condition, lower liquid can the index of occasion recovered energy very low, unit efficiency is only about 20-30%, flow lower than rated flow 40% time, even can become wasted work machine.
Summary of the invention
The object of this invention is to provide a kind of energy that can carry out energy recovery recycling and recycle radial suction booster.
Technological scheme of the present invention is: stator and rotor are linked together by rotor connecting part; Described stator by turbine body, pump cover and the pump housing three part form, the left and right sides of pump cover is respectively arranged with turbine body and the pump housing, and pump cover is provided with axis hole; Be fixed with stator dish between turbine body and pump cover, the stator blade on stator dish is connected with stator controlling mechanism; Be provided with the sliding bearing bearing radial force in the axis hole of pump cover, in the pump housing, be provided with the bearing support of supporting thrust bearing;
Rotor connecting part forms primarily of radial turbine, axle, impeller and thrust bearing; Axle is through the axis hole of pump cover, and its two ends are respectively in turbine body and the pump housing; Tightening nut is used to be fixed on by radial turbine on the axle head in turbine body; Impeller and thrust bearing to be through successively on the axle head being positioned at the pump housing and to use tightening nut to fix; Be linkage structure between stator blade on described stator dish; Described turbine design is blade is spatial warping blade, and the outlet laying angle of the bent twisted blade in space is 85 ~ 100 degree.
Shaft end in the pump housing is also provided with a mechanical seal.
Two rectangular base are provided with bottom the pump housing and turbine body.
Advantage of the present invention is: radial turbo-power pump will decrease 1 motor for double-ended drive, 3 cover coupling, 1 cover clutch than traditional pump reversion turbine.And energy recycles radial suction booster pump and hydraulic turbine is become one.Thus greatly reduce the expense that energy recycles the cost of radial suction booster and the maintenance of unit.
Radial suction booster has higher efficiency compared with common water pump, and provides reliability because progression reduces.Energy recycles the turbine of radial suction booster compared with conventional pump impeller, can produce higher energy conversion efficiency, reclaims larger pressure reduction.Adopt radial turbine, can obtain more high efficiency under identical progression, reliability does not also reduce simultaneously.Owing to adopting the diameter of radial turbine relatively little, therefore compact structure, cost are low.If lift is very high or selected motor speed is lower, and common water pump must, with the speed operation higher than pump group, therefore need to add step-up gear between water Pump and Electromotor.Equally, if the water pump that subscriber selector stage number is lower (generally at about 10 grades), then reduction gear box must be provided.The larger advantage of radial blade turbine design is the size that can change nozzle, connects, easily change because the nozzle on ring runner is bolt.Such suction booster just has best working efficiency, and the scope of design discharge is also wider simultaneously.
In sum, energy such as recycles radial suction booster and has that cost is low, material is saved, structure is simple, floor space is little, efficiency is high, recovered energy is many at the feature.
