Abstract
The utility model discloses an automatic exhausting device for an electric diving pump, which comprises an active carbon filter 110, a vent pipe 112, a closed ball 118, a closed ball chamber body 115, a columnar chamber body 117, an exhaust cap 119 and a filter screen 116. The filter screen 116 is installed at the bottom of the columnar chamber body 117; the upper part of the columnar chamber body 117 is connected with the closed ball chamber body 115; the exhaust cap 119 is installed at the upper part of the closed ball chamber body 115; and the closed ball 118 is positioned in the closed ball chamber body 115. An annular groove is formed at the lower part of the exhaust cap 119, and an O-shaped ring can be installed in the annular groove. The upper part of the exhaust cap 119 is connected with the vent pipe 112; and the vent pipe 112 is connected to the active carbon filter 110. The air in an impeller chamber can be completely exhausted when the electric diving pump is started; therefore, the idle time of the electric diving pump is reduced; mechanical seal of the electric diving pump is protected; the service life of the electric diving pump is prolonged; and the use cost of the electric diving pump is lowered. During normal operation of the electric diving pump, water medium cannot flow out of vents, so that energy is saved.
Description
Technical field
The utility model relates to a kind of automatic vent part of the automatic exhaust device that is used for Submerged Motor Pumps, especially Submerged Motor Pumps.
Background technique
Submerged Motor Pumps has been widely used in the industrial and agricultural production field in the world.Shown in accompanying drawing 1; Submerged Motor Pumps 101 generally is installed in the sump 102, is installed to through automatic coupling device 103 on the base of sump bottom, on the rising pipe 105 of Submerged Motor Pumps; Safety check 104 generally is installed, be used to prevent Submerged Motor Pumps shut down the back pipeline in aqueous reflux.When water level reach a certain height in sump, water pump can start under the control of manual control or automatic control system, and the water in the sump is discharged.
When Submerged Motor Pumps normally uses, be full of aqueous medium in the impeller cavity of water pump.But, have two kinds of situation exceptions at least: after the first installation of water pump, in the time of on the base of Submerged Motor Pumps bottom guide rod is installed to sump; Perhaps the drawdown in sump is below horizontal to the water pump vane chamber, when the water surface raises again then, and all can residual air in the impeller cavity of Submerged Motor Pumps.Because the sealing process of Submerged Motor Pumps rising pipe upper check valve; When Submerged Motor Pumps started once more, these air that remain in the impeller cavity can not disappear automatically, not only can cause the dally phenomenon of not water outlet of Submerged Motor Pumps; Also can damage the mechanical seal structure of Submerged Motor Pumps, reduce water pump working life.
At present, the method for residual air has two in the solution Submerged Motor Pumps impeller cavity: one is the mode through the manual work venting.Be starting mode of pump front opening safety check, utilize the water in the rising pipe to reflux, these residual airs are extruded outside the impeller cavity.But this method only is applicable to manually operated situation, and is when the running state of automatic controlling system Submerged Motor Pumps, just infeasible.A kind of in addition method is on impeller cavity, to stay an aperture, and when starting mode of pump, air can be discharged in this hole.But during because of the Submerged Motor Pumps running, aqueous medium can be emerged in this hole always, so this method can be lost a part of power of Submerged Motor Pumps.
Summary of the invention
The utility model technical problem to be solved is; Overcome the problem that exists in the existing technology; A kind of automatic exhaust device that is used for Submerged Motor Pumps is provided, and this device is mainly used in Submerged Motor Pumps air in the emptying impeller cavity when starting, and reduces the water pump idle running time; Protection mechanical water pump sealing prolongs water pump working life.
For the technological scheme that addresses the above problem the utility model is such:
A kind of automatic exhaust device that is used for Submerged Motor Pumps comprises activated carbon filter 110, breathing pipe 112, airtight ball 118, airtight ball cavity 115, column cavity 117, smoke releasing cap 119, filter screen 116.Filter screen 116 is installed in column cavity 117 bottoms, and column cavity 117 tops connect airtight ball cavity 115, and smoke releasing cap 119 is installed on airtight ball cavity 115 tops, and airtight ball 118 places in the airtight ball cavity 115.
Annular groove is arranged at smoke releasing cap 119 bottoms, and ' O ' type circle can be installed.Smoke releasing cap 119 tops link to each other with breathing pipe 112, and breathing pipe 112 is connected to activated carbon filter 110.
Beneficial effect, Submerged Motor Pumps is the air in the emptying impeller cavity when starting, and reduces the Submerged Motor Pumps idle running time, and the mechanical seal of protection Submerged Motor Pumps prolongs Submerged Motor Pumps working life, reduces the Submerged Motor Pumps user cost.When Submerged Motor Pumps ran well, aqueous medium can not flow out from exhaust port, saved the energy.
