Abstract
A kind of herein described breather hole structure for preventing oil spilling, including the air-vent being arranged at the top of centrifugal pump, air-vent is provided with vertical tracheae, tracheae top is provided with top cap, stomata is provided between the gentle tube top end of top cap, the length of tracheae is more than 5 centimetres, because tracheae is higher, lubricating oil is difficult to reach the height, effectively avoids lubricating oil from being sprayed at outside centrifugal pump.
Description
Technical field
The application is related to a kind of breather hole structure, specifically, is related to a kind of breather hole structure for preventing oil spilling.
Background technology
Centrifugal pump has the diversified forms such as vertical, horizontal, single-stage, multistage, single suction, double suction, self-priming.Centrifugal pump is to utilize leaf
Wheel rotates and makes water that centrifugal motion occur and carry out work.Water pump is before activation, it is necessary to makes to be full of water in pump case and suction hose, then
Start motor, pump shaft impeller and water is done high speed rotary motion, water occurs centrifugal motion, impeller outer edge is thrown toward, through snail
The runner of shape pump case flows into the pressure pipe road of water pump.
Addition lubricating oil lubricates, it is necessary to set air-vent to breathe freely at the top of centrifugal pump in centrifugal pump, but due to
The rotation of centrifugal pump, lubricating oil are often emerged from ventilative hole site, and the outside of centrifugal pump is stained with lubricating oil, it is difficult to clean, and
And need frequent make-up oil.
Apply for content
The shortcomings that the application overcomes in the prior art, there is provided a kind of breather hole structure for preventing oil spilling, it is effectively kept away
Exempt from lubricating oil to be sprayed at outside centrifugal pump, keep centrifugal pump neat and tidy, it is not necessary to frequent make-up oil is time saving and energy saving.
In order to solve the above-mentioned technical problem, the application is achieved through the following technical solutions：
It is a kind of to prevent the breather hole structure of oil spilling, including the air-vent at the top of centrifugal pump is arranged at, the air-vent is set
There is vertical tracheae, the tracheae top is provided with top cap, stomata, the length of the tracheae are provided between the gentle tube top end of top cap
Degree is more than 5 centimetres.
Further, the tracheae is provided with annular swab case.
Further, the annular swab case is provided with oil well pump, and the bottom of the oil well pump connects the inside of the centrifugal pump.
Further, the annular swab case is provided with screen pack.
Further, the annular swab case is provided with detachable receipts oil box.
Further, the tracheae is provided with the recess for being used for placing adsorption paper close to the top cap position.
Further, the pipe is provided with support, and the support is provided with screw element, the top cap and the screw element spiral shell
Connect.
Compared with prior art, the beneficial effect of the application is：
It is herein described it is a kind of prevent the breather hole structure of oil spilling, including be arranged at the air-vent at the top of centrifugal pump, breathe freely
Hole is provided with vertical tracheae, and tracheae top is provided with top cap, and top cap is provided with stomata between gentle tube top end, and the length of tracheae is more than
5 centimetres, because tracheae is higher, lubricating oil is difficult to reach the height, effectively avoids lubricating oil from being sprayed at outside centrifugal pump.
Brief description of the drawings
Accompanying drawing is used for providing further understanding of the present application, is used to explain the application together with embodiments herein,
The limitation to the application is not formed, in the accompanying drawings：
Fig. 1 is a kind of schematic diagram of herein described breather hole structure for preventing oil spilling.
In figure, 1 --- centrifugal pump；2 --- air-vent；
3 --- tracheae；4 --- top cap；
5 --- stomata；6 --- recess；
7 --- annular swab case.
Embodiment
The preferred embodiment of the application is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein preferred real
Apply example and be merely to illustrate and explain the application, be not used to limit the application.
Embodiment 1：
As shown in figure 1, it is herein described it is a kind of prevent the breather hole structure of oil spilling, including be arranged at the top of centrifugal pump 1
Air-vent 2, air-vent 2 are provided with vertical tracheae 3, and the top of tracheae 3 is provided with top cap 4, is provided between top cap 4 and the top of tracheae 3
Stomata 5, the length of tracheae 3 is 10 centimetres, and because tracheae 3 is higher, lubricating oil is difficult to reach the height, effectively avoids lubricating oil from spraying
It is sprinkled upon outside centrifugal pump 1.
Meanwhile sometimes due to the rotating speed of centrifugal pump 1 is too fast, lubricating oil spilling is still suffered from, the outside of tracheae 3 connects oil provided with annular
Box 7, annular swab case 7 are provided with detachable receipts oil box, when detachably storing excessive lubricating oil in receipts oil box, can pull down down
Fall.
Tracheae 3 is provided with the recess 6 for being used for placing adsorption paper close to the position of top cap 4, posts adsorption paper in recess 6, will overflow
Lubricating oil sop up, prevent lubricating oil viscosity on tracheae 3.
The inside of tracheae 3 is provided with support, and support is provided with screw element, and top cap 4 and screw element are spirally connected, and can rotate regulation top cap 4
With the position of screw element, to adjust the size of stomata 5.
Embodiment 2：
The present embodiment and the technical scheme of embodiment 1 are essentially identical, and something in common repeats no more, and its difference is：
Annular swab case 7 is provided with screen pack, filters out the debris in lubricating oil, and annular swab case 7 is provided with oil well pump, oil pumping
The inside of the bottom connection centrifugal pump 1 of pump, lubricating oil is extracted into inside centrifugal pump 1, used again.
Finally it should be noted that：The preferred embodiment of the application is these are only, is not limited to the application, although
The application is described in detail with reference to embodiment, for those skilled in the art, it still can be to foregoing
Technical scheme described in each embodiment is modified, or to which part technical characteristic carry out equivalent substitution, but it is all
Within spirit herein and principle, any modification, equivalent substitution and improvements made etc., the protection of the application should be included in
Within the scope of.
