Abstract
The invention relates to a seal coupling structure used for a high-lift diving pump, which is composed of a coupling junction panel, a water outlet of the diving pump and a coupling elbow. The coupling junction panel is fixed with an upper-side shell body and is provided with a groove with an inclined plane, the upper-side shell body of an entrance end of the coupling elbow is embedded into the groove in the coupling junction panel, the rear side of the shell body at the upper side of the entrance end of the coupling elbow is provided with an inclined plane matching with the groove, the back side of the lower part of a contacting flange of the water outlet of the diving pump water is provided with an inclined plane, a locking shim block is fixed on the lower-part shell body of the entrance end of the coupling elbow and is provided with an inclined plane which matches with the inclined plane at the back side of the lower part of the contact flange. The invention adds a lower-part locking device into a prior coupling structure of the diving pump; when the pump lift of the diving pump is larger than 60 meters, the jet power of water at the water outlet of the pump can not cause gaps between the contact flange and the entrance end of the coupling elbow, thereby guaranteeing fine sealing effect and no leakage.

Background technique:
Submersible pump comprises submersible type pollution discharge pump, submersible type axial-flow pump and submersible type mixed flow pump, is widely used fluid transmit machine.The submersible pump compact structure, convenient for installation and maintenance, the pumping plant investment is little, and noise is low, the motor cool condition is good, the pumping plant good operation conditions, pumping plant builds up underground type, can save superstructure, and the pumping plant investment is little, floor space is little, do not influence surface structures or greening, control flood and drain flooded fields, being used widely in field such as field irrigation, urban construction, water conservancy construction, is the substitute products of traditional water pump.In the prior art, submersible pump adopts the coupling mounting type, pumping the fixedly connected plate that is of coupled connections on the mouth of a river, the inclined-plane that is of coupled connections on the plate combines with inclined-plane on the coupling bend pipe, assurance is pumped the mouth of a river and is combined with coupling bend pipe entrance point, utilize the gravitational moment of the weight generation of pump, make and pump plane, the mouth of a river and compress and seal with coupling bend pipe entrance point interplanar, but when pumping head increases, pumping mouth of a river water pressure increases, the recoil force of water will increase, and when gravitational moment that the recoil moment of water produces greater than the weight of pump, pump plane, the mouth of a river and coupling interface interplanar and will open an angle, cause that water leaks, pumping head is reduced, and pump is in big flow running state, motor overload or tripping operation.。
Summary of the invention:
The purpose of this invention is to provide a kind of sealing coupling structure that is used for high-lift submersible pump, the coupling mounting structure that the described this sealing coupling structure that is used for high-lift submersible pump will solve the prior art submersible pump is in the technical problem that water leaks, pumping head reduces that is used for when high-lift.
This sealing coupling structure of high-lift submersible pump that is used for of the present invention is by the plate that is of coupled connections, submersible pump water outlet and coupling bend pipe constitute, described submersible pump water outlet place is provided with adpting flange, the described plate that is of coupled connections is fixedlyed connected with the last side body of submersible pump water outlet, be of coupled connections and be provided with groove in the plate with inclined-plane, the last side body of the entrance point of coupling bend pipe embeds the groove in the plate that is of coupled connections, the housing rear side of coupling bend pipe entrance point upside is provided with the inclined-plane with groove fit, dock with coupling bend pipe entrance point plane on submersible pump water outlet plane, wherein, the bottom dorsal part of described adpting flange is provided with an inclined-plane, be fixedly connected with a locking wedge block on the lower case of the entrance point of described coupling bend pipe, described locking wedge block is provided with the inclined-plane, and the inclined-plane on the locking wedge block cooperates with the inclined-plane of adpting flange bottom dorsal part.
Further, described locking wedge block is fixedlyed connected with the lower case of coupling bend pipe entrance point by screw.
Working principle of the present invention is: the adpting flange of submersible pump water outlet axially cooperates with the entrance point of coupling bend pipe, the adpting flange of plate with the submersible pump water outlet is connected with coupling bend pipe entrance point by being of coupled connections, the other end of plate of being of coupled connections is arranged on the guide rail by circular hole, fit in the inclined-plane of the adpting flange bottom of locking wedge block and submersible pump water outlet, and apply pretightening force by screw, adpting flange and coupling bend pipe entrance point close-coupled with the submersible pump water outlet, even at the submersible pump lift during greater than 60 meters, the recoil force of pump outlet place water also can not make the adpting flange of submersible pump water outlet and be coupled and produce the gap between the bend pipe entrance point, guarantee good sealing, can not cause leakage.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention increases the locking device that is provided with the bottom in existing submersible pump coupled structure, at the submersible pump lift during greater than 60 meters, the water recoil force of pump outlet can not make between adpting flange and the coupling bend pipe entrance point and produce the gap, thereby can guarantee good sealing, can not cause leakage.
