Abstract
The invention discloses a gear pump with a water cooling system. The gear pump comprises a driving shaft, a driven shaft and a pump shell. The driving shaft is connected with an external power shaft and sleeved with a driving gear, the driven shaft is sleeved with a driven gear, and the driving gear and the driven gear are linearly engaged. A front end cover and a rear end cover are arranged on two sides of the pump shell respectively. The pump shell comprises an outer pump shell body and an inner pump shell body, the inner pump shell body is provided with a spiral water way, the outer pump shell body is provided with two threaded holes communicated with the spiral water way, and a water inlet pipe and a water outlet pipe are arranged at the two threaded holes respectively. According to the scheme, the gear pump with the water cooling system has the beneficial effects that a cooling water passage is formed in the pump shell, cooling water takes away heat inside the gear pump in time during work of the gear pump, and therefore the temperature inside the gear pump keeps at a proper range all the time. The service life of the gear pump is prolonged, and the gear pump is simple in structure and good in heat radiation effect.
Description
Technical field
The present invention relates to gear pump, be specially a kind of gear pump with constituent.
Background technique
Gear pump is commonly used for conveying various liquid or the power oil pump as hydraulic transmission, and gear pump causes the change of the volume of working space by the revolution of driving gear and driven gear, and then reaches the object of suction liquid.The advantage of gear pump is that volume is little, lightweight, part is few, easy to manufacture, easy to maintenance.But gear pump is in running, and its inside easily produces high temperature, because gear pump mainly relies on pump housing surface to carry out heat loss through radiation, and pump housing surface radiating is limited in one's ability, timely the high temperature of gear pump inside can not be shed, thus reduce the working life of gear pump.
Summary of the invention
The invention is intended to provide a kind of can in time the high temperature of gear pump inside be distributed, improve the gear pump of the band constituent in working life.
The gear pump of the band constituent in this programme, comprise driving shaft, driven shaft and pump case, driving shaft is connected with external impetus axle, and on driving shaft, cover has driving gear, and on driven shaft, cover has driven gear, driving gear linearly engages with driven gear, pump case both sides are respectively equipped with front cover and rear end cover, and pump case comprises outer pump case and interior pump case, and interior pump case offers spiral channel, outer pump case has two tapped holes communicated with described spiral channel, tapped hole place is respectively equipped with intake pipe and outlet pipe.
The working principle of this programme is: external impetus axle drives driving gear running by driving shaft, the driven gear engaged with driving gear operates round about, the tooth of driving gear and driven gear passes into cooling water to intake pipe while carrying out joggleword, the tooth of driving gear and driven gear constantly engaging-in, engage, nibble out, throw off, will a large amount of heats be produced in the process that engages again, this heat outwards sheds and is delivered to pump case, is left fast by heat under the effect of the cooling water in pump case.
The beneficial effect of this programme is: by arranging cooling water passage in pump case, taken away in time by the heat of cooling water by gear pump inside in gear pump working procedure, thus make the temperature of gear pump inside remain on suitable scope, improve the working life of gear pump, and this structure is simple, good heat dissipation effect.
Further, in order to ensure the sealing effect of intake pipe and outlet pipe and outer pump case cooperation place, intake pipe and water outlet pipe part are equipped with seal ring.
Further, in order to reduce cooling water by resistance during spiral channel, the cross section of spiral channel is inverted trapezoidal structure.
Further, enter to prevent external fluid the work that front cover has influence on gear pump, front cover offers seal groove.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
