Abstract
The utility model relates to a water pump matched with a gasoline engine, which is mainly composed of an output shaft 1 of the gasoline engine, a bracket pump shell body 2, connecting screws 3, an impeller 4, and a water inlet end cover 5, wherein, the impeller 4 arranged in a pump body is arranged on a power output shaft 1 which extends into the pump body; one side of the pump body is connected with a power machine by a supporting bracket, and the other side of the pump body is provided with a water inlet port. The utility model is characterized in that the pump body and the supporting bracket are a casting connection integral structure to form the bracket pump shell body 2; one side of the bracket pump shell body 2 is arranged on the gasoline engine by connecting screws, and the other side is arranged on the water inlet end cover 5 by the screws. The utility model enables the supporting bracket and the pump body to be designed into the casting connection integral structure, and solves the problems of difficult assembly of the supporting bracket and the pump body; the utility model is provided with the water inlet end cover 5 which is separated from the shell body of the pump to be convenient for the installation of the impeller 4.
Description
One, technical field:
The utility model relates to a kind of water pump, especially a kind of being used for and the matching used miniature gasoline engine clean waterpump of petrol engine.
Two, background technique:
At present, great majority and diesel engine, the matching used water pump of motor, because the output shaft of diesel engine and motor is longer, have very big fixing clearance between support separately and the pump case, support and pump case coupled together can not have any problem, but during with this water pump and the supporting use of petrol engine, because the output shaft of petrol engine is shorter, so that just have only very little installing space between support and the pump case, the difficulty that causes the user to be not easy to install can't supportingly be used this traditional water pump and petrol engine.
Three, summary of the invention:
The purpose of this utility model provide a kind of can with the matching used miniature gasoline engine clean waterpump of petrol engine, solve because of output shaft of gasoline engine shortly, and cause bearing support and pump housing assembling to connect difficult problem.
Concrete scheme of the present utility model is: a kind of miniature gasoline engine clean waterpump, impeller in the pump housing is installed on the pto that stretches in the pump housing, one side of the pump housing is connected with power engine by bearing support, the opposite side of the pump housing is the water inlet port, it is characterized in that: the pump housing and bearing support constitute the support pump case for connection casting overall structure; One side of support pump case is installed on the petrol engine by connecting screw, and opposite side is installed intake end cover by screw.
Adopt the beneficial effect of such scheme to be: because the output shaft of petrol engine is very short, the bearing support and the pump housing to be made as a connection casting overall structure, to have solved the problem of the bearing support and pump housing assembling difficulty; An intake end cover that separates with pump case is set, is convenient to the installation of impeller, it is very convenient that entire equipment is installed, reliable transmission.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five, embodiment:
As can be seen from Figure 1: the utility model is made up of output shaft of gasoline engine 1, support pump case 2, connecting screw 3, impeller 4, intake end cover 5, impeller 4 in its middle pump body is installed on the pto 1 that stretches in the pump housing, one side of the pump housing is connected with power engine by bearing support, the opposite side of the pump housing is the water inlet port, it is characterized in that: the pump housing and bearing support constitute support pump case 2 for connection casting overall structure; One side of support pump case 2 is installed on the petrol engine by connecting screw, and opposite side is installed intake end cover 5 by screw.
Installation process of the present utility model is: a side of support pump case 2 is installed on the petrol engine by connecting screw 3, the output shaft 1 of petrol engine stretches in the support pump case 2, then impeller 4 is installed on the output shaft 1 of petrol engine, again intake end cover 5 usefulness screws is installed in the opposite side of support pump case 2.
