Description
Technical field
The present invention relates to the pump class field in universal machine, especially a kind of leak of blowdown self priming pump is warned device.
Background technology
The type pumped in pump class industry is varied, and the basic function of pump is exactly pressurization or promotes trip body, this medium has
Pulp water, sewage, chemical liquid, slurry, oil etc..Its basic structure has vane type and positive displacement etc..
Have on front side of existing blowdown self-priming pump bearing body fore bearing only there are one outside framework oil seal, if mechanical seal damages
When medium being caused to be leaked from mechanical seal place, medium will cross outside framework oil seal and enter bearing intracoelomic cavity, and bearing body is caused to get rusty,
To influence the operating of bearing, and this is all happened at pump body, is not seen outside the pump housing, results in a finding that the time of damage
It greatly prolongs.
Invention content
It warns device therefore, the purpose of the present invention is to provide a kind of leak of blowdown self priming pump, is opened by bearing body one end
Mouthful at install make water leakage leak out bearing body outside device, realize when mechanical seal damage cause water to leak when, prevent water into
Enter bearing body internal corrosion bearing body, solves operation, control and the debugging mode for being rusted inside bearing body and bringing to user extremely
Inconvenient problem.
A kind of leak of blowdown self priming pump of the present invention is warned device, including bearing body, the first outside framework oil seal and the second bone
Frame oil sealing；The bearing body both ends are designed with opening, and first outside framework oil seal and the second outside framework oil seal one in front and one in back have spacing
The opening being arranged in described bearing body one end, the bearing body other end connect with bearing cap；The bearing body is described
It is additionally provided with groove between first outside framework oil seal and the second outside framework oil seal, for preventing the water of leakage from entering the second outside framework oil seal.It lets out
The water of leakage can pass through the first outside framework oil seal, then flow into groove so that not have water inflow in bearing body.
Further, the bearing body is additionally provided with the drainage channel for draining away the water of leakage, and the drainage is logical
Road one end is connected to the groove, and the other end is connected to outside bearing body, for warning.When there is water leakage, water can pass through groove
It flows into drainage channel, and is flowed into outside bearing body by drainage channel, allow people can be from the external machine quickly known in the pump housing
Tool bad seals.
Further, the spacing distance between first outside framework oil seal and the second outside framework oil seal is more than the groove both sides
The distance between wall.
Further, the distance of the interval 10-20mm between first outside framework oil seal and the second outside framework oil seal.Distance is such as
Fruit setting is too small, if mechanical seal damage is excessive so that leakage water is excessive, and flow is during leakage since inertia can rush
It crosses groove to reach at the second outside framework oil seal and across the second outside framework oil seal enter in bearing body, equally can also make in bearing body in this way
It gets rusty.
Further, a waste meter is additionally provided with below the outlet that the other end of the drainage channel and bearing body outside are connected to
Measuring tank, for observing and counting water leakage.When leak, external staff only will appreciate that mechanical seal damages in the pump housing, but not
Know that the size of damage, leak measuring tank side wall are equipped with scale, personnel can set the period certainly, observe the leak within the period
In measuring tank water level rise number, to judge size that mechanical seal in the pump housing is lost, to make corresponding judgement.
Beneficial effects of the present invention：The device for making water leakage leak out outside bearing body is installed at bearing body one end open, is realized
When mechanical seal damage causes water to leak, prevents water from entering bearing body internal corrosion bearing body, solve inside bearing body
It is rusted the problem for operation, control and the debugging mode extremely inconvenience brought to user.
Description of the drawings
It, below will be to specific in order to illustrate more clearly of the specific embodiment of the invention or technical solution in the prior art
Embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In attached drawing, each element or part are not
Centainly drawn according to actual ratio.
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
The embodiment of technical solution of the present invention is described in detail below in conjunction with attached drawing.Following embodiment is only used for
Clearly illustrate technical scheme of the present invention, therefore be only used as example, and the protection model of the present invention cannot be limited with this
It encloses.
As shown in Figure 1：A kind of leak of blowdown self priming pump of the present embodiment is warned device, including bearing body 1, the first skeleton
Oil sealing 2 and the second outside framework oil seal 3；1 both ends of the bearing body are designed with opening, first outside framework oil seal, 2 and second skeleton oil
Envelope 3 one in front and one in back has the opening of spacing being arranged in 1 one end of the bearing body, 1 other end of the bearing body to connect with bearing cap
It connects；The bearing body 1 is additionally provided with groove 4 between first outside framework oil seal, 2 and second outside framework oil seal 3, is leaked for preventing
Water enter the second outside framework oil seal 3；The bearing body 1 is additionally provided with the drainage channel 5 for draining away the water of leakage, described
5 one end of drainage channel is connected to the groove 4, and the other end is connected to outside bearing body 1, for warning.The water of leakage can pass through the
One outside framework oil seal 2, then flow into groove 4 so that water inflow is not had in bearing body 1, and when there is water leakage, water can pass through
Groove 4 flows into drainage channel 5, and is flowed into outside bearing body 1 by drainage channel 5, and people is allowed quickly can to know pump from outside
Internal mechanical seal damages.
As a specific embodiment, the spacing distance between first outside framework oil seal, 2 and second outside framework oil seal 3
More than the distance between 4 two side of the groove；Interval 10- between first outside framework oil seal, 2 and second outside framework oil seal 3
The distance of 20mm.If distance setting is too small, if mechanical seal damage is excessive so that leakage water is excessive, and flow is being revealed
Reach at the second outside framework oil seal 3 and in the second outside framework oil seal 3 entrance bearing body 1 since inertia can break through groove 4 in the process,
It equally can also make to get rusty in bearing body 1 in this way.
As a specific embodiment, under the outlet being connected to outside the other end and bearing body 1 of the drainage channel 5
Side is additionally provided with a leak measuring tank 6, for observing and counting water leakage.When leak, external staff only will appreciate that mechanical in the pump housing
Bad seals, but the size of damage is not known, 6 side wall of leak measuring tank is equipped with scale, and personnel can set the period certainly, sees
Examine within the period that water level in leak measuring tank 6 rises number, to judge mechanical seal is lost in the pump housing size, to do
Go out corresponding judgement.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, it will be understood by those of ordinary skill in the art that：Its according to
So can with technical scheme described in the above embodiments is modified, either to which part or all technical features into
Row equivalent replacement；And these modifications or replacements, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme should all cover in the claim of the present invention and the range of specification.
