Abstract
The utility model belongs to a gear pump, particularly to the gear pump with antiacid and antiwear functions. According to the design proposal offered by the utility model, a driving shaft and a driven shaft are arranged on a casing, and a gear is arranged on one section of the driving shaft, which is positioned in the casing. The gear which is engaged with the gear is arranged on the driven shaft to form a pair of gear pairs, and an inlet and an outlet of a material are arranged on the casing. The utility model is characterized in that an inner wall of a hollow cavity containing the gear pairs in the casing is provided with a ceramic plate. In the device, by changing a structure of the gear pump, the antiacid and the antiwear performances of the gear pump are improved.
Description
Technical field
The utility model belongs to a kind of gear pump, and specifically a kind of have a gear pump acidproof, wear-resisting functions.
Background technique
The effect of gear pump is to carry liquid, and its working principle is to drive intermeshing a pair of gear by transmission device to rotate the volume-variation of utilizing between cog, liquid is delivered to the place that needs.In the prior art, used gear pump is mainly made by ordinary metallic material, and is acidproof and wear-resisting property is poor, can't carry to have corrosive material.
Summary of the invention
The purpose of this utility model is to design a kind of stainless gear pump, by changing the structure of gear pump, improves the acidproof and wear-resisting property of gear pump.
According to design proposal provided by the utility model, driving shaft and driven axle are installed on housing, be positioned at driving shaft on a section of housing gear is installed, gear with gear engagement is installed on driven axle, form a pair of gear pair, the import and the outlet of material are set on housing, it is characterized in that: the cavity inner wall that holds gear pair in housing is provided with ceramic plate.
Housing is made up of sheet in the middle of being arranged in and the forward and backward lid that is connected in the sheet both sides, and ceramic plate is arranged at the inwall of forward and backward lid.Connecting part at ceramic plate and forward and backward lid is provided with sealing strip.Connecting part at driving shaft and forward and backward lid is provided with axle sleeve respectively.Be provided for the jump ring and the flat key of fixed gear in the connecting part of gear and driving shaft and driven axle.Driving shaft stretches out between end of protecgulum and protecgulum the flange circle is set, and between flange circle and driving shaft outside framework oil seal is set.
The utility model has the advantages that: owing to be provided with ceramic plate at the inwall of gear pump, improved the wear-resisting and decay resistance of gear pump, make this device can be used to transport and have corrosive material, both prolonged the working life of equipment, enlarged the applicable situation of equipment again.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in the figure: driving shaft 16 and driven axle 17 are installed on housing, be positioned at driving shaft 16 gear 5 is installed on a section of housing, on driven axle 17, install and gear 5 meshed gears, form a pair of gear pair, the import 19 and outlet 20 of material are set on housing, and the cavity inner wall that holds gear pair in housing is provided with ceramic plate 10.During work, motor drives driving shaft 16 rotates, and the gear that the gear 5 on the driving shaft 16 drives on the driven axle 17 rotates, and the volume-variation when utilizing gear to rotate sucks material from import 19, discharge by outlet 20 again, is delivered to the place that needs.Owing to the ceramic plate 10 that has inwall being provided with than high abrasion and decay resistance, prolonged the working life of gear pump, enlarged the applicable situation of gear pump.
For ease of I﹠M, housing can be made up of sheet 6 in the middle of being arranged in and the forward and backward lid 11,4 that is connected in sheet 6 both sides, and at this moment, ceramic plate 10 should be arranged at the inwall of forward and backward lid 11,4.Connecting part at ceramic plate 10 and forward and backward lid 11,4 is provided with sealing strip 2, to improve its sealability.Connecting part at driving shaft 16 and forward and backward lid 11,4 is provided with axle sleeve 13,1 respectively.Be provided for the jump ring 9 and the flat key 3 of fixed gear in the connecting part of gear and driving shaft 16 and driven axle 17.An end and 11 of protecgulums that driving shaft 16 stretches out protecgulum 11 are provided with flange circle 14, between flange circle 14 and driving shaft 16 outside framework oil seal 15 are set.
Among the figure 8,12 is seal ring, and 7 is taper pin, 18 bolts for sheet 6 in connecting and forward and backward lid 11,4.
