Description
Technical field
The utility model relates to a kind of leakage proof locking mechanism, particularly relates to a kind of proof submersible sand discharging pump coupling the leakage proof locking mechanism is installed.
Background technique
Proof submersible sand discharging pump is compact, convenient for installation and maintenance because of pump structure; Noise is low, the motor cool condition is good; Pumping plant builds up underground type, and floor space is little, does not influence surface structures or greening; Can build into garden landscape type pumping plant; Favored by the user, thus 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 conventional dry water pump.
When proof submersible sand discharging pump uses, most of manifold type mounting type that adopts, installation and maintenance are very convenient; So receive praises from customers, but high-head pump (pumping head H＞50m) maybe be because the effect of the dynamical reaction of water causes coupling part poorly sealed; Cause actual water outlet lift not reach; Or because of coupling part seriously leaks, the pump actual motion is at big flow, low lift point, and motor overload even pump can't start because of overload.
Existing proof submersible sand discharging pump coupling device structure.Show like Fig. 1 and 2; Its principle is: utilize the position, inclined-plane of the plate 4 that is of coupled connections to combine with the inclined-plane of coupling base 3; Assurance is pumped the mouth of a river 6 and is combined with coupling base water intake 7, and the gravitational moment that relies on the pump own wt to produce makes and pumps plane, the mouth of a river and compress and seal with base water intake 7 interplanars that are coupled.
When pump head than higher, it is high promptly to pump mouth of a river water pressure, the recoil force of water will increase; When gravitational moment that the recoil moment of water produces greater than the weight of pump, an angle will be opened between base water intake 7 plane interfaces with being coupled in the pump outlet plane, produce displacement; Thereby cause that the water leakage causes leakage place like 8 places of the sign among Fig. 2 for being washed open by water easily; Cause pump head to reduce, pump is in big flow running state, motor overload or tripping operation.
Poorly sealed in order to solve high-lift proof submersible sand discharging pump coupling device, so need design a kind of proof submersible sand discharging pump coupling the leakage proof self-locking structure is installed.
The model utility content
To the problems referred to above, the main purpose of the utility model is to provide a kind of proof submersible sand discharging pump coupling that the leakage proof locking mechanism is installed.
The utility model solves above-mentioned technical problem through following technical proposals: the leakage proof locking mechanism is installed in a kind of proof submersible sand discharging pump coupling; Said mechanism comprises the leakage proof locking mechanism; Said leakage proof locking mechanism is to be fixed on the band wedge shape incline device that connects on the coupling base of proof submersible sand discharging pump; The periphery of leakage proof locking mechanism also is the narrow down wide wedge shape that, and proof submersible sand discharging pump connects the coupling base through the plate that is of coupled connections.
In the practical implementation example of the utility model, the leakage proof locking mechanism of wedge shape is locked on the coupling base through bolt.
The positive progressive effect of the utility model is: the proof submersible sand discharging pump coupling that the utility model provides is installed the leakage proof locking mechanism and had the following advantages: the utility model connects the device on a band wedge shape inclined-plane on the coupling base; This inclined-plane combines with the inclined-plane of pump discharge flange bottom; After the water pump coupling installs; Wedge shape incline device on pump outlet wedge shape inclined-plane and the coupling base closely cooperates, and through bolt locking; Thereby assurance pump discharge flange can not washed open by the recoil force of water, reaches the effect of sealing; The utility model has not only solved the high-head pump coupling leakage problem has been installed; And improved the submersible pump application area, and improved system's operational reliability, well satisfied user's usage requirement.
Description of drawings
Fig. 1 is similar prior art constructions schematic representation.
Fig. 2 be similar existing technology possibly washed open the structural representation that causes leakage by water.
Fig. 3 is the structural representation of the utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technological scheme of the utility model.
Fig. 3 is the structural representation of the utility model; As shown in Figure 3: the utility model comprises leakage proof locking mechanism 1; Leakage proof locking mechanism 1 is to be fixed on the band wedge shape incline device that connects on the coupling base 3 of proof submersible sand discharging pump 2; The periphery of leakage proof locking mechanism 1 also is the narrow down wide wedge shape that, and proof submersible sand discharging pump 2 connects the coupling bases through the plate 4 that is of coupled connections.The leakage proof locking mechanism 1 of wedge shape is locked on the coupling base through bolt 5.
The utility model specifically is achieved in that keeping on the existing proof submersible sand discharging pump coupling basis easy for installation, on coupling device, does suitably to improve, to satisfy the sealing of high-head pump.The concrete improvement as follows: exit of pump flange bottom, process a wedge shape inclined-plane, when this inclined-plane must guarantee that the pump coupling is installed, convenient butt joint also combined.The device that on the coupling base, connects a band wedge shape inclined-plane; This inclined-plane combines with the inclined-plane of pump discharge flange bottom, after the water pump coupling installs, and the wedge shape incline device on pump outlet wedge shape inclined-plane and the coupling base; Closely cooperate; And through bolt locking, thereby guarantee that the pump discharge flange can not washed open by the recoil force of water, reach the effect of sealing.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
