Abstract
The utility model relates to a multifunctional gear pump belonging to the pump technical field, particularly the technical field of gear oil pumps. The utility model comprises a front and a back covers, a median plate, a gear, a driving and a driven shafts, bearings, a flange ring and a seal ring; the utility model also comprises skeleton type seal components, wherein, two skeleton type seal components are respectively arranged before the front and the back covers and the median plate. The utility model extends service lives of the shafts and the bearings. The utility model not only can be used for oils, but also can be worked under malconditions such as water, water glass, burning oil, subacidity, printing ink, tar, etc. The service life can be enhanced more than one time when the utility model is used for motor oil.
Description
The utility model belongs to the pump technical field, particularly the gear oil pump technical field.
Existing gear oil pump generally is that a rubber seal is set outside the pump housing, and axle journal mouth oil does not leak when acting on oil, but when being used for other medium, and axle is soon by unlubricated medium, impurity wearing and tearing with corrode, and working life is extremely short.
The purpose of this utility model provides a kind of multifunctional gear pump that increases the service life and can be used for multiple medium.
Now be described in detail technology contents of the present utility model:
The utility model comprises forward and backward lid, middle sheet, gear, driving shaft, driven shaft, bearing, flange circle, seal ring, and it also comprises skeleton Sealing.Before the protecgulum of pump, bonnet bearing, respectively be provided with skeleton Sealing, block unlubricated medium and enter bearing.
Skeleton Sealing preferably adopts anti-high speed, resistant to elevated temperatures Sealing.
Preferably be provided with the trapped fuel groove in the forward and backward lid axis hole.
Bearing preferably adopts the DU bearing.
The utility model has the advantages that:
Because after before forward and backward lid bearing, respectively having set up the skeleton Sealing of 2 anti-high-speed and high-temperatures, unlubricated medium, impurity can not enter in the bearing, the fixedly lubricant oil of setting up in the axis hole, also not to external leakage, thereby prolonged working life of axle and bearing, and can the many usefulness of a pump, not only be applicable to oil, also can be used for mal-condition work such as water, water glass, combustion oil, little acid, printing ink, tar.The life-span can be enhanced about more than once when being used for machine oil.
Accompanying drawing is a structural representation of the present utility model.
1 is flange circle, the 2nd among the figure, seal ring, the 3rd, protecgulum, the 4th, gear, the 5th, middle sheet, the 6th, bonnet, the 7th, garden taper pin, the 8th, driving shaft, the 9th, driven shaft, the 10th, skeleton seal ring, the 11st, unlubricated DU bearing, the 12nd, socket head screw.
Now introduce embodiment in conjunction with the accompanying drawings:
As shown in the figure, the utility model comprises protecgulum, middle sheet, bonnet, gear, master and slave moving axis, bearing, flange circle, seal ring, and it also comprises skeleton Sealing, before protecgulum 3,6 liang of side bearings of bonnet, respectively be provided with 2 skeleton Sealings 10, block unlubricated medium and enter bearing.
The preferably anti-high speed of skeleton Sealing 10, resistant to elevated temperatures skeleton Sealing.
In protecgulum 3, bonnet 6 axis holes, be provided with the trapped fuel groove.
Bearing 10 preferably adopts unlubricated DU bearing.
Claims (4)
1, a kind of multifunctional gear pump, peace comprises protecgulum, middle sheet, bonnet, gear, driving shaft, driven shaft, bearing, flange circle, seal ring, it is characterized in that, it also comprises skeleton Sealing, before protecgulum, bonnet bearing, respectively be provided with skeleton Sealing, block unlubricated medium and enter bearing.
