Abstract
The utility model discloses a take the water cooling system gear pump, including driving shaft, driven shaft and pump case, the driving shaft is connected with outside power shaft, and the cover has the driving gear on the driving shaft, and the cover has driven gear on the driven shaft, driving gear and the linear meshing of driven gear, the pump case both sides are equipped with front end housing and rear end cap respectively, the pump case includes outer pump case and interior pump case, has seted up spiral water channel on the interior pump case, division have on the outer pump case two and the communicating screw hole of spiral water channel, screw hole punishment do not is equipped with inlet tube and outlet pipe. The utility model discloses a beneficial effect is: through set up the cooling water passageway in the pump case, by freezing water is in time taken away the inside heat of gear pump in the gear pump working process to make the inside temperature of gear pump keep in suitable scope, improved the life of gear pump, and this simple structure, the radiating effect is good.
Description
Technical field
The utility model relates to toothed gear pump, is specially the toothed gear pump of a kind of band water-cooling system.
Background technology
Toothed gear pump is commonly used for the various liquid of conveying or the power oil pump as Vulcan gear, and toothed gear pump causes the change of the volume of working space by the revolution of driving toothed gear and follower gear, and then reaches the object of suction liquid. The advantage of toothed gear pump is that volume is little, weight is light, part is few, easy to manufacture, easy to maintenance. But, toothed gear pump is in operational process, and its inside easily produces high temperature, owing to toothed gear pump mainly relies on pump housing surface to carry out heat loss through radiation, and the ability of pump housing surface heat radiation is limited, timely the high temperature of toothed gear pump inside can not be fallen apart away, thus reduce the work-ing life of toothed gear pump.
Practical novel content
The utility model is intended to provide a kind of and can be distributed by the high temperature of toothed gear pump inside in time, it is to increase the toothed gear pump of the band water-cooling system in work-ing life.
The toothed gear pump of the band water-cooling system in this scheme, comprise main drive shaft, driven shaft and pump case, main drive shaft is connected with external impetus axle, and on main drive shaft, cover has driving toothed gear, and on driven shaft, cover has follower gear, driving toothed gear linearly engages with follower gear, pump case both sides are respectively equipped with front end end cover and rear end cap, and pump case comprises outer pump case and interior pump case, and spiral channel offered by interior pump case, having two threaded holes communicated with described spiral channel on outer pump case, threaded hole place is respectively equipped with water inlet pipe and rising pipe.
The principle of work of this scheme is: external impetus axle drives driving toothed gear running by main drive shaft, the follower gear engaged with driving toothed gear operates to reverse direction, the tooth of driving toothed gear and follower gear leads to into water coolant to water inlet pipe while carrying out joggleword, the tooth of driving toothed gear and follower gear constantly nibbles, engage, nibble out, disengage, will produce a large amount of heats in the process that engages again, this heat outwards falls apart to be delivered to pump case, is left fast by heat under the effect of the water coolant in pump case.
The useful effect of this scheme is: by arranging cooling-water duct in pump case, toothed gear pump working process is taken away in time by the heat of water coolant by toothed gear pump inside, thus the temperature making toothed gear pump inside remains on suitable scope, improve the work-ing life of toothed gear pump, and this structure is simple, good heat dissipation effect.
Further, in order to ensure water inlet pipe and the sealing effect of rising pipe and outer pump case combination section, water inlet pipe and water outlet pipe part are equipped with sealing-ring.
Further, in order to reduce water coolant by resistance during spiral channel, the cross section of spiral channel is inverted trapezoidal structure.
Further, enter the work that front end end cover has influence on toothed gear pump in order to prevent external fluid, front end end cover has been offered sealing groove.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
