The technique effect of this anti-overheat submersible pump：When submersible pump works, while motor shaft impeller rotates
Drive drive bevel gear, drive bevel gear driving cycle pump in pump shaft, then drive driving blade work, because driving blade turn
The dynamic pressure differential caused in cooling circular passage so that coolant starts to flow, and transmits heat, during by pump case internal channel, with
Heat exchange occurs for fluid, completes the whole process of cooling cycle.
In a kind of above-mentioned anti-overheat submersible pump, the gearratio of the carrying bevel gear and drive bevel gear is 1:
2 to 1:3.Improve the slewing rate of circulating pump so that the rotating speed of the rotating ratio impeller of driving blade is fast, improves the effect of cooling cycle
Rate.
It is to be detachably connected between the circulating pump and pump case in a kind of above-mentioned anti-overheat submersible pump.When following
When ring pump breaks down, circulating pump can integrally be taken out to maintenance or replacement, convenient operation, avoids losing time.
In a kind of above-mentioned anti-overheat submersible pump, the pump case is removable with being provided with the corresponding end wall of circulating pump
The movable end cover unloaded, the end cap are used to help take out circulating pump.
In a kind of above-mentioned anti-overheat submersible pump, the left and right sides channel width of the cooling circular passage is not right
Claim design.The not reciprocity effect of pressure is caused, improves the runner speed of cooling agent in cooling circular passage.
Compared with prior art, this anti-overheat submersible pump is provided with cooling recirculation system, and cooling recirculation system helps will
The heat transfer of motor is gone out so that motor is not in superheating phenomenon, helps submersible pump work more longlasting, has work
Make the advantages of performance is stable, service life is long.
