Abstract
The utility model provides a novel coupling sealing pad which is an important part for a sealing system of a coupling interface installation component. The characteristics of the novel coupling sealing pad are as follows: when a high-lift volute type submersible pump is in normal running, the interface separation caused by the generated water thrust can be balanced by the elastic deformation of the coupling sealing pad and the torque generated by the dead weight of the pump, so as to make sure that the pump can run under the designed working conditions. Meanwhile, the sealing pad can also exert the function of shock absorption, so as to reduce collision among devices, thereby prolonging the service life of the devices.
Description
Affiliated technical field
The utility model relates to a kind of novel coupling interface sealing gasket, and sealing is installed in the coupling that is specially adapted to high-lift scroll casing type submersible pump.
Background technique
At present, Chang Yong coupling interface is too high because of pump head when the coupling of high-lift pump is installed.Even water pump and coupling have conventional sealing between base, but the torque of water pump deadweight makes water pump rotate when being not enough to resist the waterpower torque.Thereby produce the slit between water pump and coupling interface, the water pump partial discharge flows away from the slit that produces.Pump head obviously reduces after the partial discharge loss, and water pump turns back to original design attitude again.Water pump is behind former design attitude, and the slit at water pump and coupling interface place disappears, and pump head raises again and makes water pump rotate.Circulate repeatedly like this, can produce two problems: 1, pump head instability can not meet design requirement; 2, water pump because of there not being good protective measure, makes that whole device vibration is big in rotating process repeatedly, even jeopardizes water pump working life.
Summary of the invention
In order to overcome the installation leakage problem of high-lift scroll casing type submersible pump, make more reliable operation of whole device.The utility model provides a kind of new coupling sealing means, and this coupling sealing gasket makes that water pump can be when high-lift work, makes that the sealing between water pump and coupling device is reliable, the operation of device safety and reliability by self distortion.
The technological scheme that its technical problem that solves the utility model adopts is: pump body outlet moves after coupling is installed automatically with after coupling sealing flange and coupling sealing gasket connect by fastening piece.To be coupled base and water pump of coupling sealing gasket separates, and effectively stoped the collision between installing.The sealing gasket that is coupled simultaneously can overturn when high-lift and be close to the coupling base, has sealed the gap between sealing flange and coupling base reliably, has guaranteed that water pump does not have leakage.Even water pump rotates, also can owing to the coupling sealing gasket can be on water (flow) direction deformable seal the gap of coupling base and pump house, the increase of the torque of water pump itself simultaneously, assurance base and pump house reliable sealing.
This coupling is installed special-purpose sealing gasket by water pump, coupling sealing flange, coupling sealing gasket, slide plate, coupling base, and the formation that is linked in sequence is characterized in that: described coupling sealing gasket elastically deformable.This coupling sealing gasket is that rubber material is made, coupled position strap bolt hole locating slot.Sealing pad endoporus position has produced elasticity upset distortion during work under the fluid pressure effect, has filled up the gap between the joint.
The beneficial effects of the utility model are, have improved high-lift scroll casing type submersible pump reliability of operation, make that the sealing between water pump and base is more reliable, thereby have satisfied designing requirement installing.

Fig. 2 is a structural drawing of the present utility model.
Fig. 3 is the user mode of the utility model sealing.
Among Fig. 1: part 1. scroll casing type submersible pumps, part 2. coupling sealing flanges, part 3. coupling slide plates, part 4. coupling bases, part 5, guide rail.
Among Fig. 2: part 1. scroll casing type submersible pumps, part 2. coupling sealing flanges, part 3. coupling slide plates, part 4. coupling bases, part 5, guide rail, part 6. coupling sealing gaskets.
Among Fig. 3: part 1. scroll casing type submersible pumps, part 2. coupling sealing flanges, part 3. coupling slide plates, part 4. coupling bases, part 5, guide rail, part 6. coupling sealing gaskets.
Structural principle is analyzed
In Fig. 1, scroll casing type submersible pump outlet (part 1) and coupling sealing flange (part 2) and coupling slide plate (part 3) form an integral body with after the Bolt Connection, slide and the base that is coupled (part 4) is promptly finished installation after docking along guide rail (part 5).During work, this ordinary construction device is put into liquid, after liquid pressurizes by water pump, come out when overcoupling sealing flange (part 2) and coupling base (part 4) from pump housing outlet port, can make because of the waterpower torque is too high between coupling sealing flange (part 2) and coupling base (part 4) and produce relative rotation, form the gap, the part current flow away from the slit, influence the proper functioning of water pump.After flow lift reduced then, water pump was got back to original position again and may be bumped with coupling base (part 4).After keeping in the center, the lift of water pump raises, and the torque of water pump reduces, and water pump has and will rotate, and like this, forms circulation repeatedly.Go down for a long time even can influence the safe operation of whole device.
In Fig. 2, scroll casing type submersible pump outlet (part 1) connects with coupling sealing flange (part 2) and coupling sealing gasket (part 6).Again with coupling slide plate (part 3) with after the Bolt Connection, forms an integral body, slide and the base that is coupled (part 4) is promptly finished installation after docking along guide rail (part 5).During work, the utility model structure is put into liquid, and liquid comes out from pump housing outlet port by after the water pump pressurization, and the torque that causes that rotates increases the torque that comes balance waterpower to cause by the resiliently deformable of the sealing gasket (part 6) that is coupled and water pump.Make that sealing is reliable between water pump and coupling base (part 4), the application of the sealing gasket that is coupled simultaneously (part 6) has significantly reduced the impact force of water pump with coupling base (part 5), makes that the life-span of device is longer.
Among Fig. 3, sealing gasket breaks away from the situation of coupling base (part 5) running state among description Fig. 2 at water pump.At this moment, because the effect of hydraulic thrust makes water pump and base break away from.Hydraulic thrust acts on the coupling sealing gasket (part 6) simultaneously, makes coupling sealing gasket (part 6) produce the upset distortion, has filled up gap between the two, guarantees reliable sealing.
