Abstract
The utility model mode relates to a light centrifugal pump, which is characterized in that a pressure spring is arranged in a pump body in order to prolong the service life of the centrifugal pump. The light centrifugal pump which can be matched with a small four wheel tractor has the advantages of simple and portable structure, simple manufacture and convenient usage.
Description
The utility model relates to a kind of centrifugal pump that is mainly used in farmland pouring usefulness.
At present the centrifugal pump of widespread usage in the rural area have several as: 3833 centrifugal water pump RK6 type centrifugal pumps because these centrifugal pump volume heavinesses are unsuitable for present rural area operating type so difficulty is installed.
The utility model is in order to overcome the deficiency of existing several centrifugal pumps, and it is little to design a kind of volume, in light weight, particularly the New Centrifugal Pump of long service life.
Technical characterstic of the present utility model is to realize like this, as accompanying drawing 1, it is made up of impeller chimney 1, the pump housing 4, impeller 2, axle 8, belt pulley 9, oil seal 13 etc., belt pulley 9 is by the motor drives rotation and by impeller 2 rotations in the axle 8 drive pump housings 4, make the water in the water source be inhaled in the pump housing 4 because the rotation of impeller 2 produces a kind of draft, and flow out from the B mouth by the A mouth.In order to guarantee the working life of axle 8, use two oil seal circles 13 air enters in the lubricated axle in the water to control at the stage casing of axle 8 adding lubricant oil and at two ends, usually, the working life of 2 oil seal circles 13 is very short, for the maintenance frequency that reduces axle 8 working life that improves oil seal circle 13, on the jack shaft 8 of two oil seal circles, be inserted in a spring 6, the working life of improving two oil seal circles such as axle 8 with the tension force of spring 6.
Using great advantage of the present utility model is that volume is light, and it is few that wheel is repaiied number of times, long service life, and can drive use by little device wheel tractor.
Accompanying drawing: the structural drawing of light body centrifugal pump.
The concrete structure of model utility is provided by following embodiment:
As shown in the figure, be bumped into belt at an end of axle 8, wheel 9 and 2 bearings 7, jump ring 12, and an oil seal circle 13, and axle 8 is inserted in the pump housing 4.The other end at the pump housing 4 is inserted in spring 6 in the axle 8, adds oil seal circle 13, tumbles in impeller 2 at last and installs wheel cover 1.
Claims (2)
1, a kind of light body Centrifugal water pump that is mainly used in farmland pouring usefulness, it is made up of impeller chimney 1, the pump housing 4, impeller 2, axle 8, belt pulley 9, oil seal washer 13, the axle 3 of centrifugal pump is inserted in the pump housing 4, it is that motor passes through belt 9 and produces that the end that 2 bearings and 7 oil seal circles 13, axle 8 be housed on axle 8 studs with rotating force that belt pulley 9, the other end stud with liquid wheel 2, axle 8, it is characterized in that: be with a spring 6 in the middle of two oil seal circles of axle 8.
2, light body centrifugal pump according to claim 1, it is characterized in that the pump housing 4 and belt pulley 9 can with the supporting use of common tractor with small four wheels, the pump housing 4 can be installed on the tractor rear guard, by the belt pulley drive work of tractor clutch.
