Abstract
The utility model discloses an improved water pump which comprises a water pump end cap, a pump body, an impeller, a pump shaft, a bearing and a thermostat body. The pump body and the thermostat body are fixedly connected into a whole. An empty cavity is arranged in the pump body. One end of the pump body is connected with a belt wheel, and the other end of the pump body is fixedly connected with the water pump end cap through a screw. The pump shaft penetrates through the belt wheel and is arranged in the empty cavity of the inner side of the pump body. The end of the pump shaft located in the empty cavity of the inner side of the pump body is connected with the impeller in a sleeved mode. The bearing is arranged on a position close to the belt wheel end in the empty cavity of the inner side of the pump body. The pump body of the improved water pump and the thermostat body are integrated in design, the thermostat body is formed in a pouring mode when the pump body is poured, the thermostat does not need to be machined separately, a port for installation of the thermostat body does not need to be cast on the pump body, and an installation hole does not need to be provided and machined on a diesel engine either, so production cost is effectively reduced, and assembly efficiency when the water pump is assembled onto the diesel engine is improved.
Description
Technical field
The utility model relates to the water pump of using on a kind of automobile.
Background technique
The belt pulley that water pump one end arranges drives water pump bearing and wheel rotation under the effect of motor, cooling liquid in the water pump is driven together rotation by impeller, under the effect of centrifugal force, be thrown toward the edge of water pump cover, produce simultaneously certain pressure, then flow out from water outlet or water pipe.The reciprocation cycle of cooling liquid is realized because cooling liquid is thrown out of and pressure decreased, and the cooling liquid in the water tank is inhaled in the impeller through water pipe in the center of impeller under the differential pressure action at unit fixed on water pump suction and impeller center.In the process of cooling liquid reciprocation cycle, the thermostatic valve of the control coolant temperature of water pipe setting is the important composition parts of coolant temperature in the control water pump; Normal employing is after the thermostat body is cast out in the prior art, be installed on the diesel engine frame after machining separately, need to arrange the interface that the thermostat body is installed on the pump housing, also need to reserve the space that the thermostat body is installed at the diesel engine that water pump is installed simultaneously, such design, increased cost of production, efficiency of assembling is also extremely low simultaneously.
The model utility content
For the deficiency of above-mentioned existence, the utility model provides the improvement type that a kind of cost of production is low, efficiency of assembling is high water pump.
In order to reach the foregoing invention purpose, the technological scheme that the utility model is taked is for providing a kind of improved water pump, this water pump comprises water pump end cap, the pump housing, impeller, pump shaft, bearing and thermostat body, it is characterized in that: the described pump housing is fixedly connected with the thermostat body and is integral; Described pump body is provided with a cavity, and an end of the pump housing is connected with belt pulley, and the other end is fixedly connected with the water pump end cap by screw; Pump shaft passes in the cavity that belt pulley is arranged on pump body, and that end that pump shaft is positioned at the pump body cavity is socketed with impeller; Described bearing is arranged on the pump body cavity and closes on pulley end.
Preferably, the contacted plane layout of water pump end cap and the pump housing has pump housing pad.
Preferably, be provided with the integrated type water seal between the pump shaft in impeller left side and the pump housing.
Preferably, two contacted faces of bearing are provided with lining.
Preferably, the contacted end face of bearing and belt pulley is provided with the bearing lock ring.
The beneficial effects of the utility model are in sum: the integrated design of the pump housing and thermostat body, namely in the cast pump housing, just directly cast out the thermostat body, the thermostat body does not need independent processing, need to not cast out the interface that the thermostat body is installed at the pump housing, need to mounting hole be set at diesel engine yet, effectively reduce cost of production, improved water pump and be assemblied in efficiency of assembling on the diesel engine.
