Abstract
A kind of oil-filling type water pump, relates to the technical field of water pump, and bearing support and the pump housing are installed fixing, and live axle is fixed in the center hole of bearing support, and bearing gland is fixed on bearing support the other end end; Bearing support is inner, near bearing gland position mounting sealing device; Seal arrangement is fixed on bearing support, and seal arrangement is made up of primary seal device and two stage sealing device; Primary seal device is built in two stage sealing device, and is provided with inflator between primary seal device and two stage sealing device; Pipeline bottom is connected with primary seal device, and pipeline top is connected with gas-filled pump, and inductor is connected with controller, and controller is connected with gas-filled pump.Adopt such design; closed cavity is formed between two-stage seal arrangement; can to be asked to seal arrangement by inflator and be blown into shielding gas; not only increase sealing effect like this, avoid water in water pump flow into the improper damage of caused bearing in bearing and affect the generation of the phenomenons such as the normal work of water pump simultaneously.
Description
technical field:
The utility model relates to the technical field of water pump, is specifically related to a kind of oil-filling type water pump.
background technique:
At present, middle-size and small-size water pump one be all made up of the live axle of the pump housing, the impeller be arranged in the pump housing, drives impeller and the component such as bearing support of installing live axle.In above-mentioned water pump structure; usually can there is the phenomenon of the improper damage of bearing; the main cause of this defect is caused to be due to defect in existing water pump structure; cause the easy insufficient lubrication of bearing; and sealability is poor; easily make the water in water pump flow in bearing, thus cause the improper damage of bearing, and have influence on the normal work of water pump.
summary of the invention:
The purpose of this utility model is the deficiency existed to overcome above-mentioned prior art, and a kind of oil-filling type water pump is provided, overcome existing for existing water pump: bearing seal poor performance, cause bearing that the defect of improper damage easily occurs, and the defect of the water pump cisco unity malfunction caused therefrom.
In order to achieve the above object, the utility model adopts following technological improvement:
A kind of oil-filling type water pump, by bearing, seal arrangement, inflator and inductor four part form; Together with bearing support to be fixed on the pump housing by the flange of its end, one end, live axle is fixed in the center hole of bearing support by two radial ball bearings, and bearing gland is screwed in the end of the bearing support the other end; Inside at bearing support, the fixed installation of the position near bearing gland seal arrangement; Seal arrangement is fixed on bearing support by being with the double-threaded screw of spring, and described seal arrangement is made up of the primary seal device of ring set type and two stage sealing device; Primary seal device is built in two stage sealing device, and is provided with inflator between primary seal device and two stage sealing device; Inflator is made up of a few part of pipeline, flexible pipe, inductor, controller and gas-filled pump; The bottom of pipeline is connected with primary seal device, the top of pipeline is connected by flexible pipe with the gas-filled pump be arranged on two stage sealing device, inductor on two stage sealing device inwall is connected with the controller on two stage sealing device outer wall, and controller is connected with gas-filled pump.
As further improvement of the utility model, the both sides of described bearing are provided with oil-filling device.
As further improvement of the utility model, one end that described live axle is arranged on inside the pump housing is provided with impeller.
The utility model, through above-mentioned technological improvement, reaches following beneficial effect:
Adopt such design; closed cavity is formed between two-stage seal arrangement; can to be asked to seal arrangement by inflator and be blown into shielding gas; not only increase sealing effect like this, avoid water in water pump simultaneously and flow into the improper damage of caused bearing in bearing and have influence on the generation of the phenomenons such as the normal work of water pump.
accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of oil-filling type water pump of the utility model.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described further:
