Description
Technical Field
The utility model relates to a gear drive technical field, in particular to gear pump.
Background
Gear pumps are rotary pumps that deliver or pressurize fluid by virtue of the change in working volume and movement created between a pump cylinder and a meshing gear. Two gears, pump body and front and back covers form two closed spaces, when the gears rotate, the space on the gear disengagement side becomes larger from smaller to larger to form vacuum to suck liquid, and the space on the gear engagement side becomes smaller from larger to smaller to squeeze liquid into the pipeline. The suction chamber and the discharge chamber are separated by a meshing line of two gears. The pressure at the discharge of the gear pump is entirely dependent on the amount of resistance at the pump outlet.
When the existing gear pump works, a certain gap exists between the gear cover and the rear cover, so that when the existing gear pump works, the pressure of liquid in the mounting chamber of the driving gear is relatively small when the liquid is squeezed into the mounting chamber of the driven gear, and the power of the existing gear pump cannot meet the requirements of enterprises.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a gear pump to the pressure of liquid when crowded driven gear's installation indoor of installation of driving gear among the solution prior art is less relatively, thereby makes its not enough problem of power.
In order to solve the technical problem, the utility model discloses a scheme does:
the utility model provides a gear pump, includes the gear lid, gear lid lower extreme is provided with the gear lid bush, the gear lid bush is fixed through the locating pin, gear lid bush lower extreme is provided with driven gear, and is adjacent driven gear's one end is provided with the driving gear, the driving gear with driven gear meshes, all connect through the bearing in driven gear and the driving gear, the driving gear rear end is provided with the back lid, be provided with back lid bush between back lid and the driving gear, the gear lid with be provided with the sealing washer between the back lid.
Preferably, the sealing ring is an "O" shaped sealing ring.
Preferably, the oil pump further comprises an oil inlet nozzle communicated with the mounting chamber for mounting the driving gear and an oil outlet nozzle communicated with the mounting chamber for mounting the driven gear.
Preferably, a base plate is arranged between the gear cover and the rear cover, and the base plate is sleeved with the sealing ring.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a set up the gear bush at gear cover lower extreme to fix through the locating pin, and cover after and also set up corresponding back lid bush, thereby make the utility model discloses the leakproofness for the gear pump among the prior art on the leakproofness is better, simultaneously through being provided with the backing plate between gear cover and back lid, and the sealing washer cover is located on the backing plate, further improved the utility model discloses an air tightness to increase the pressure of the interior liquid of installation room of driving gear when crowded into driven gear's installation room, improve with this the utility model discloses power when using.
