Abstract
The utility model belongs to the field of water pumps, and particularly relates to a water storage structure of a water pump, which comprises a water seal gland and a weep hole, wherein the water seal gland is mounted on a pump shaft of the water pump and spaces out an impeller chamber and a bearing chamber; the weep hole is formed on a water pump casing between the water seal gland and the bearing chamber; the water storage structure further comprises a reservoir; and the reservoir is mounted in the water pump casing with one end being connected with the weep hole and the other end being connected to the exterior of the pump body via a water outlet thereof. Due to the adoption of such a structure including the reservoir, false drip can not flow out of the water outlet directly during normal operation of the water pump, whereas true drip flows out of the water outlet during abnormal operation of the water pump, thereby helping users distinguish false or true drip of the water pump, and reducing the failure rate of false drip of the water pump.
Description
Technical field
The utility model belongs to the water pump field, particularly relates to a kind of water pump water storage structure.
Background technique
In water pump, support the bearing of water pump spindle and need use grease lubrication, therefore to prevent that the leak of liquid in the blade wheel chamber from causing lubricating grease emulsification in bearing chamber, also will prevent a large amount of leakages of liquid in the blade wheel chamber simultaneously.The water pump that uses prevents that the seal approach of leaking from having water seal and sealing gasket at present.Water seal rotary packing ring and axle are contained between impeller and the bearing by interference fit, on the water seal static seal seat housing that leans against water pump tightly, thereby reach the purpose that seals liquid in the blade wheel chamber.
Because the inherent characteristic of water seal, the cooling liquid that has minute quantity spills in the middle of water seal, and this is a normal phenomenon, is called false leaking.For water and the bearing chamber that will spill separates, have spilled water hole on the water seal of water pump and the housing between the bearing chamber usually, in case the liquid permeates water seal is arranged, can release from spilled water hole, enter bearing chamber to prevent liquid, and destroy bearing lubrication and parts corrosion.If still have cooling liquid to spill after water pump stops, this is called true property and leaks, and shows that then water seal damages.
But most of user does not understand the false difference of leaking and leaking with true property, thinks that it is leakage from water pump that spilled water hole there are flowing out, thereby changes water seal even water pump, causes unnecessary expense and maintenance cost.
Summary of the invention
The utility model provides a kind of simple in structure for solving the technical problem that exists in the known technology, is easy to judge the water pump water storage structure of leakage from water pump character.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of water pump water storage structure comprises water seal, spilled water hole, and described water seal is installed on the pump shaft of water pump, and blade wheel chamber and bearing chamber are separated; Described spilled water hole is on the water pump cover between water seal and the bearing chamber; Described water pump water storage structure also comprises wet pit; Described wet pit is cast in the described water pump cover, and an end connects spilled water hole, and the other end is connected to pump housing outside by its water outlet.
The utility model can also adopt following technical measures:
Described wet pit is connected to the pump shaft hole of described pump shaft by described spilled water hole.
Advantage and the good effect that the utlity model has are:
The utility model is owing to adopted structures such as spilled water hole, wet pit, water outlet, false leaking when making the water pump proper functioning can directly do not flowed out from water outlet, and the true property during the water pump non-normal working is leaked from water outlet and is flowed out, thereby the true and false property that helps the user to distinguish water pump is leaked, and has reduced the false rate of fault of leaking of water pump.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Among the figure: 1, water seal; 2, spilled water hole; 3, wet pit; 4, water outlet; 5, housing; 6, pump shaft hole; 7, pump shaft; 8, blade wheel chamber; 9, cavity.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, a kind of water pump water storage structure mainly is made up of water seal 1, spilled water hole 2, wet pit 3, water outlet 4.Have pump shaft hole 6 on the water pump cover 5, pump shaft 7 is positioned at pump shaft hole 6 and can freely rotates therein.One end of pump shaft 7 is connected with the impeller in the blade wheel chamber 8, the bearing fixing that the other end is carried by pump shaft 7.On the pump shaft 7 between blade wheel chamber 8 and the bearing water seal 1 is installed, has spilled water hole 2 on the pump shaft hole 6 between water seal 1 and the bearing.Wet pit 3 is cast in the water pump cover 5, and its shape is decided according to the shape of housing 5.One end of wet pit 3 is connected to pump shaft hole 6 by spilled water hole 2, and the other end is connected to pump housing outside by water outlet 4.
Working principle of the present utility model:
(1) working principle during false leaking
Owing to be penetrated with pump shaft 7 between the blade wheel chamber 8 of water pump and the bearing, in order to the water seal 1 of isolating blade wheel chamber 8 and bearing mechanical wear can take place, thereby can't seal fully between blade wheel chamber 8 and the bearing in addition.
And water pump in the course of the work, can produce certain heat, makes the operative liquid water in the blade wheel chamber 8 be converted into water vapour, forms certain air pressure in blade wheel chamber 8; Some disturbance of pump working environment simultaneously also can make the internal pressure of water pump become big.When the pressure of blade wheel chamber 8 acquired a certain degree, the water in the blade wheel chamber 8 just can infiltrate cavity 9 between blade wheel chamber 8 and the bearing by water seal 1, and then discharges by the spilled water hole on the pump shaft hole 62, is stored in the wet pit 3.False leaking under the water pump proper functioning promptly taken place this moment.When the water pump temperature was higher, the water in the wet pit 3 can be evaporated in the atmosphere, and can directly not flow out from water outlet 4, and avoiding making the user to think by mistake is that the water pump damageability leaks.
Working principle when (2) true property is leaked
Cause water seal 1 to lose efficacy when water seal 1 is aging, or when causing water in the blade wheel chamber 8 to enter in the wet pit 3 in a large number and fast owing to reasons such as water pump damages, leaking just can be full of wet pit 3, and then flows out from water outlet 4, and the true property that promptly taken place under the water pump non-normal working this moment is leaked.When water outlet 4 leaks, just can in time remind the customer inspection impeller and the pump housing, to avoid further damaging the loss that causes because of water pump.
The above only is to preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification that above embodiment did, equivalent variations and modification all belong in the scope of technical solutions of the utility model.
