Abstract
The utility model relates to a direct-connection type water pump with a gasoline engine. A rotary impeller in a pump body is connected with the end of a rotary power output shaft of a gasoline engine by a spiral structure along the axial direction through a lengthening extension end on a rotary shaft line. The utility model has the advantages of simple structure, small size and convenient use.
Description
The utility model relates to the water pump that can directly connect type with petrol engine.
Water pump, particularly small pump are a kind of agriculture common equipments, the common and supporting use of petrol engine.The supporting mode of present this water pump and petrol engine is generally two kinds.A kind of is to make the two connection through coupling mechanisms such as coupling or belt pulleys.This connection complex forms, pump structure are also comparatively complicated, and the rotary blade of pump must be installed on the special axis, and are installed on the bearing bracket stand with the supporting of pair of bearings body, could connect with petrol engine through coupling or belt pulley again.Therefore its structure member is many, and the cost of production height is installed and used inconvenience.Another kind is that the rotary blade with water pump is contained on the extension shaft, connects with the rotating power output shaft of petrol engine by parts such as this extension shaft and corresponding keys.Though this kind mode is comparatively simple, because the axial dimension of the pump that extended, pump structure increases, and manufacture cost also increases.
The purpose of this utility model is at above-mentioned situation, provide a kind of can with the water pump of petrol engine direct-connection type, make it can simplified structure, reduce volume, and convenient the use.
In the structure of of the present utility model and petrol engine direct-connection type water pump, the rotary blade in its pump housing links through helix structure with the end of petrol engine rotating power output shaft vertically with the lengthening extension part on its spin axis.For a most step makes compact structure, reduce total volume, the bonnet of the pump housing also can be connected in the attachment side end of petrol engine simultaneously.Should be provided with waterproof sealing body within this pump housing bonnet and between the lengthening extension part of rotary blade this moment, flows into petrol engine to prevent the high pressure water in the pump.
For ease of in multiple environment, using, and be convenient to substitute water pump and enlarge Applicable scope, can make petrol engine be connected with the arrangement base through bearing support with other machinery.
In the said structure of the utility model direct-connection type water pump, because the lengthening extending end of rotary blade through its axis place in the pump directly connected with helix structure with the output shaft of petrol engine, not only simplified the structure of water pump, and can reduce the axial dimension of pump to greatest extent, also reduced cost of production.The connecting mode of helix structure both had been convenient to install and use, and also was convenient for changing into other farm machinery, was convenient to this petrol engine and realized a tractor serves several purposes.Safe and reliable on guarantee using, the Hand of spiral of this helix structure, the sense of rotation when taking work with impeller is opposite, and promptly pump is when work, and it is good that this helix structure should make therebetween connection revolve tighter and tighter.
Below be further described with embodiment shown in the drawings.But scope of the present utility model is not limited only to down example.
Fig. 1 structural drawing of the present utility model
As shown in the figure, in this routine direct-connection type water pump, be provided with rotary blade 2 in the pump housing 1, a lengthening extension part 12 is arranged on its spin axis, directly connect through the end of helix structure vertically with the rotating power output shaft 13 of petrol engine 6.The bonnet 3 of the pump housing 1 also is connected in the attachment side end of this petrol engine 6 simultaneously through bolt 4 and 9.Be provided with waterproof sealing body 5 within the bonnet 3 and between the lengthening extension part of impeller 2, flowing into petrol engine to prevent pump inner high voltage water.Below petrol engine 6, make bearing support 7 settle base 11 to link petrol engine and dish-type with bolt 8,10.
Claims (3)
1, a kind of and petrol engine direct-connection type water pump is characterized in that the rotary blade (2) in the pump housing (1) links through helix structure with the end of the rotating power output shaft (13) of petrol engine (6) vertically with the lengthening extension part (12) on its spin axis.
2, direct-connection type water pump as claimed in claim 1 is characterized in that the bonnet (3) of the said pump housing (1) also is connected in the end of petrol engine (6) attachment side simultaneously, is provided with waterproof sealing body (5) within the bonnet and between the lengthening extension part (12) of rotary blade (2).
