Abstract
The invention provides a submersible pump coupling seal device, and relates to a submersible pump. A water outlet pipe is provided with a water outlet flange which is provided with a coupling flange. The coupling flange is provided with a seal groove, and the section of the seal groove is ladder-shaped. A seal ring is arranged in the seal groove, and the section of the seal ring is ladder-shaped. The thickness of the seal ring is larger than the depth of the seal groove. When the coupling flange is in coupling connection with the water outlet flange, one face of the seal ring protruding from the seal groove and the end face of the water outlet flange are attached and sealed. The strength of the seal ring with a ladder-shaped section is large, when vibrating, a water pump cannot be completely compressed in the seal groove, so the coupling flange is separated from the water outlet flange, metal-metal collision between the coupling flange and the water outlet flange is avoided, vibration of a pump group is reduced, and service life of the water pump is prolonged.
Description
Technical field
The present invention relates to submersible pump, say in detail it is a kind of submersible pump coupling sealing device.
Background technique
We know, existing submersible pump coupling device is to be provided with water-output flange at outlet pipe, water-output flange top is provided with the wedge shape coupling block, pump outlet is provided with the coupling flange, coupling flange top is provided with the card that is of coupled connections that cooperates installation with the wedge shape coupling block, the card that is of coupled connections is connected on the wedge shape coupling block, realizes outlet pipe and water pump automatic coupling.The sealing configuration of this submersible pump coupling device is, is provided with seal groove at the coupling flange, is provided with O-ring seals in the seal groove, and O-ring seals is to the surface of contact realization radial seal of water-output flange and coupled method your beautiful writings when being of coupled connections.When Model of pump is larger, when particularly flow is larger, the impact force that the submersible pump import is subject to is large, and submersible pump is when adopting automatic coupling, pump is suspended on the coupling device, there is not bolt closing, when pump inlet is subject to impacting, pump will produce vibration, because the decrement of O shape circle is limited, is coupled the flange meeting frequently and the collision of water-output flange generation metal and metal, the vibration aggravation, shorten the working life of pump, will damage pump in a short time when serious, thereby affect the normal operation of whole sewage disposal system.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of collision of avoid being coupled flange and water-output flange generation metal and metal is provided, reduce vibration, the submersible pump coupling sealing device that prolongs the working life of pump.
The technological scheme that the present invention addresses the above problem employing is: a kind of submersible pump coupling sealing device, outlet pipe is provided with water-output flange, water-output flange is provided with the coupling flange, it is trapezoidal seal groove that the flange that it is characterized in that being coupled is provided with the cross section, being provided with the cross section in the seal groove is trapezoidal seal ring, and the thickness of seal ring is higher than the degree of depth of seal groove.
The invention has the beneficial effects as follows, because it is trapezoidal seal groove that the coupling flange is provided with the cross section, being provided with the cross section in the seal groove is trapezoidal seal ring, the thickness of seal ring is higher than the degree of depth of seal groove, seal ring protruded the one side and water-output flange end face gluing, sealing of seal groove when coupling flange and water-output flange were of coupled connections, the cross section is that trapezoidal seal ring intensity is large, water pump can not be fully compressed in the seal groove when producing vibration, so just the coupling flange is separated with water-output flange, avoided the collision of coupling flange and water-output flange generation metal and metal, reduce the vibration of pump group, prolonged the working life of pump.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
Embodiment
Submersible pump coupling sealing device as shown in the figure, outlet pipe 1 is provided with water-output flange 2, water-output flange 2 is provided with coupling flange 3, it is trapezoidal seal groove that coupling flange 3 is provided with the cross section, being provided with the cross section in the seal groove is trapezoidal seal ring 4, the thickness of seal ring 4 is higher than the degree of depth of seal groove, seal ring protruded the one side and water-output flange end face gluing, sealing of seal groove when coupling flange and water-output flange were of coupled connections, the cross section is that trapezoidal seal ring intensity is large, water pump can not be fully compressed in the seal groove when producing vibration, so just the coupling flange is separated with water-output flange, avoided the collision of coupling flange and water-output flange generation metal and metal, reduce the vibration of pump group, prolonged the working life of pump.
