Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
By shown in Figure 3, the utility model includes reversing water pump and blower fan of cooling tower, cloth supply mains 6 tops dress reversing water pump 1, reversing water pump 1 rotatingshaft links to each other with the main shaft 3 on top, blower fan 2 is equipped with in main shaft 3 upper end portions, sealing 5 is equipped with on reversing water pump 1 top on main shaft 3, sealing 5 tops has thrust and the radial combination bearing 4 that is contained on the main shaft.
The press water of the utility model from the cooling tower feed main inserts from the former water outlet of reversing water pump 1, press water drives the water pump runner and carries out counterrotating, move in the water turbine mode, flow energy is changed into rotating mechanical energy, the power of generation directly drives blower fan 2 by main shaft.Current after the acting are got rid of through the former water intake of water pump, are connected with cooling tower cloth supply mains through pipeline.
The utility model as shown in Figure 4, is installed in reversing water pump 1 between the distribution pipe of cooling tower and the blower fan and gets final product in use, and 8 is the cooling tower shell among Fig. 4, and 7 is filler.The utility model can be effective to vertical reversing water pump and drive blower fan of cooling tower (as shown in Figure 4) and vertical horizontal pipeline formula reversing water pump reverse driving blower fan of cooling tower (as shown in Figure 5).
Positive contribution of the present utility model is: propose the theory of cooling tower blower fan apparatus driven by reversing water pump, and be applied to the type selecting of reversing water pump, realize energy-conservation and few the maintenance, reduce the purpose of operating cost.
The water pump reverse is generated electricity to have as hydraulic turbine operation and is used, and does not see precedent as yet but be used for driving blower fan of cooling tower, and both have a great difference, mainly are that the parameter and the rotation speed of fan of cooling tower water system has special restriction to reversing water pump.Select water pump to reverse when driving blower fan of cooling tower, its key problem in technology is the specific speed n that calculates water turbine with the flow of cooling tower water system, residual water head and rotation speed of fan
St, according to this as the specific speed n of water pump
Sp, according to specific speed n
SpThe size and the cooling water flow of cooling tower select Model of pump, have high efficiency in the time of could guaranteeing reversing water pump as hydraulic turbine operation.
The reversing water pump runner is imported and exported velocity triangle as shown in Figure 5.The statistical parameter of industrial cooling tower series shows, the calculating specific speed of reversing water pump should be between 50～70m.HP, calculate specific speed when selected water pump is approaching, when water pump reverses as hydraulic turbine operation, reversing water pump runner import current are that the import of nothing bump, outlet current are that (normal direction is meant the tangent direction of circle outlet to the normal direction discharge state substantially substantially, common technology title on the mobile direction of water), water can fully be changed in reversing water pump, makes reversing water pump that greater efficiency be arranged.Therefore, calculate the specific speed n of water pump with cooling tower residual water head H, flow Q and rotation speed of fan n
Sp, and then the import and export streamflow regime of check runner bucket, be the theoretical foundation that reversing water pump drives blower fan.The utility model is referred to as this theory the theory of cooling tower blower fan apparatus driven by reversing water pump.
The utility model is effective to drive blower fan of cooling tower, and the beneficial effects of the utility model are to use this reality With new technique traditional cooling tower is undergone technological transformation, substitute former drive motor and transmission mechanism, can To reach the purpose of energy-saving and environmental protection and few maintenance, reduction operating cost.
The utility model can satisfy the requirement of middle-size and small-size cooling tower fully. Cooling tower dedicated water with present use Turbine is compared, and simple in structure, the cheap and characteristics that are easy to obtain of the utility model are used for the industry cooling The tower reducing energy consumption is very convenient.
