Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, right with reference to the accompanying drawings and embodiments
The present invention is described in further detail.It should be appreciated that described herein, specific examples are only used to explain the present invention, and does not have to
It is of the invention in limiting.
A kind of self cooled magnetic drive pump of the invention, as shown in Figs 1-4, including the pump housing 1, driving shaft 2, driven shaft 3, front cover
4, rear cover 5, interior magnet coupler 6, outer magnet coupler 7 and separation sleeve 8, driving shaft 2 and driven shaft 3 are mounted in the pump housing 1, and main
Moving axis 2 protrudes from the pump housing 1, and front cover 4 and rear cover 5 are fixed on 1 two sides of the pump housing, for by 1 both sides sealing of the pump housing, separation sleeve 8 to be fixed
On rear cover 5, one end of driving shaft 2 is in separation sleeve 8, and interior magnet coupler 6 is arranged in separation sleeve 8, and is mounted on master
On moving axis 2, interior magnet coupler 6 will be divided into higher-pressure region 81 and low-pressure area 82 inside separation sleeve 8, and the outer setting of magnet coupler 7 is being isolated
Outside set 8, drive interior magnet coupler 6 to rotate by outer magnet coupler 7, to drive driving shaft 2 to rotate, and then driving shaft 2 drive from
Moving axis 3 rotates, and is cooperated by driving shaft 2 and driven shaft 3, by liquid from outlet end after the sucking of the input end 11 of the pump housing 1
12 spray, it is to be understood that, the outlet end 12 of the pump housing 1 is compared and the fluid pressure of input end 11 height, therefore, the outlet of the pump housing 1
End 12 is higher-pressure region, and input end 11 is low-pressure area 82.The outlet end 12 of the liquid pump housing 1 flow to driving shaft 2, will by driving shaft 2
Liquid leads to higher-pressure region 81, and liquid flows to low-pressure area from higher-pressure region 81 by the gap between interior magnet coupler 6 and separation sleeve 8
82, the input end 11 of the pump housing is then flow to from low-pressure area 82.
In one embodiment, as described in Figure 2,1 outlet end 12 of the pump housing and input end 11 are located at 5 side of rear cover and open up respectively
One through-hole 13 and the second through-hole 14, as shown in figure 4, driving shaft 2 is arranged radially the first guiding groove 21 being connected to higher-pressure region 81, and
And an intercommunicating pore 22 being connected to the first guiding groove 21 is axially at least set, second guiding groove 51 is set on rear cover 5, by liquid
Connecting hole 22 is led to from first through hole 13, as shown in figure 3, being provided with third through-hole corresponding with the second through-hole 14 on rear cover 5
53, so that low-pressure area 82 is connected to the input end 12 of the pump housing 1.Preferably, the pump housing 1 is provided with setting liquid storage chamber 23 at driving shaft 2,
