Abstract
The utility model relates to a water pump for the water-cooled engine of the motorcycle, mainly comprising a pump case, a cover, a water inlet, a water outlet, an impeller, a pump shaft and a seal installation. The impeller is connected with the pump shaft by a key, and is bolted on the water pump shaft; a water inlet and an wateroutlet of the pump are provided on the cover. The impeller of the water pump can be easily dismantled, which can be removed from the pump shaft by backing out the nut only. The stroke of the water flow in the pump is shortened, the bending of water course in the pump is avoided, and the resistance of water flow and pressure loss is reduced.
Description
Technical background
The utility model relates to a kind of water pump of cooling engine for motor cycle water.
Technical background
The impeller of existing water cooling engine for motor cycle water pump is direct and water pump spindle carries out scyewed joint, and the direction of rotation of thread rotary orientation and impeller, in the pump working process, the water pump spindle impeller is rotated and is made impeller more and more tighter with connecting of water pump spindle, thereby causes the impeller demolition difficulty; And the water outlet of water pump is arranged on the right crankcase inboard, causes the stroke of current in the water pump to increase, and water channel gulf song, and the water resistance that goes out of water pump is increased.
The model utility content
The purpose of this utility model provides a kind of through improved water cooling engine for motor cycle water pump, to improve the service behaviour and the usability of water pump.
Water cooling engine for motor cycle water pump described in the utility model, mainly comprise pump shell, water pump cover, water intake, water outlet, impeller, water pump spindle and seal arrangement, impeller and water pump spindle one end are fixedly connected, and be positioned at water pump cover and pump shell, impeller and water pump spindle be by key connecting, and be fastened on the water pump spindle by nut; The water intake and the water outlet of water pump all are arranged on the water pump cover.
Water cooling engine for motor cycle water pump described in the utility model because its impeller and water pump spindle be by key connecting, and is fastened on the water pump spindle by nut, in use, the dismounting of impeller is very convenient, need only back out nut, impeller can be taken off from water pump spindle.Because the water intake and the water outlet of water pump all are arranged on the water pump cover, reduced the stroke of current in the water pump, avoid the bending of water pump inner lead, thereby reduced the resistance and the pressure loss of current.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the plan view of a kind of concrete structure of water cooling engine for motor cycle water pump described in the utility model.
Embodiment
As shown in Figure 1, this water cooling engine for motor cycle water pump mainly is made up of pump shell 8, water pump cover 11, water intake 12, water outlet 10, impeller 2, water pump spindle 5 and seal arrangement, impeller 2 and water pump spindle 5 are positioned at water pump cover 11 and pump shell 8, and water pump spindle 5 is bearing in the pump shell 8 by bearing, impeller 2 is installed in water pump spindle 5 one ends by its center hole, impeller 2 carries out key connecting with water pump spindle 5 by key 3, and is fastened on the water pump spindle 5 by nut 1.The water intake 12 and the water outlet 10 of water pump all are arranged on the water pump cover 11.Seal arrangement is positioned at water pump, comprises mechanical sealing circle 4 and oil sealing 6, and it is with water pump water cavity 9 and 7 seal isolation of motor inner chamber.During use, water pump spindle 5 is connected with the machine oil pump shaft, oil pump drives water pump vane 2 by water pump spindle 5 and rotates, and cooling water enters from pump intake 12, flows out through water outlet 10 motor is cooled off.
