Through the above technical solutions, water enters from filter mantle, full of in pump case, output shaft impeller rotates water,
Under the action of centrifugal force, powder-refining with water is discharged from impeller from water outlet, and filter mantle was used for the impurity in drainage, prevents impurity blocking latent
Water pump.
Preferably, be provided with terminal box and cover on casing, terminal box is set to the side of casing, terminal box with
Casing connection, cover are set to the upper bottom surface of casing, circular hole are provided on cover, bearing is provided on circular hole, output shaft passes through
Bearing is provided with sealant, is provided with seal assembly on output shaft between circular hole and bearing.
Through the above technical solutions, being provided with bearing on circular hole, it is used to support output shaft, prevents output shaft direct with circular hole
Contact, frictional force is big, influences the working efficiency of output shaft, sealant is provided between circular hole and bearing, can prevent circular hole with
There is gap between bearing, leads to the oil leakage in casing, seal assembly is provided on output shaft, when immersible pump compares in hydraulic pressure
In the case where big, powerful hydraulic pressure can directly act on the seal assembly, on the one hand hydraulic pressure be made to be not directly placed on sealant
And bearing, the pressure that sealant and bearing are subject to is alleviated, prevents sealant and bearing from falling off, on the other hand powerful hydraulic pressure makes this
Seal assembly is close to casing, enhances the sealing performance between seal assembly and casing, therefore, in the big feelings in deep water field or hydraulic pressure
Under condition, which is still able to maintain good sealing performance.
Preferably, terminal box includes junction block and link cover of FIG, and patchboard is provided between junction block and link cover of FIG,
Binding post is provided on patchboard, one end of binding post is connect with motor lines, and the other end is connect with cable, is arranged in link cover of FIG
There is cable connection port, there is junction block chimb on junction block, base threaded hole is provided on junction block chimb, is provided in link cover of FIG
The link cover of FIG chimb being used cooperatively with junction block chimb, link cover of FIG chimb are provided with connecting hole, and junction block chimb and link cover of FIG are convex
It is provided with band on side, the gasket of protrusion is provided on band, gasket is for being arranged in junction block chimb and wiring
Between lid chimb.
By technical solution, bolt passes through connector and base threaded hole, so that on the link seat of link cover of FIG tightly,
Sealing is kept, with being connected and fixed for link cover of FIG and junction block, the sealing being set between junction block chimb and link cover of FIG chimb
Pad is compacted deformation, the contact position full of junction block chimb and link cover of FIG chimb, to further function as the effect of sealing.
Preferably, seal assembly is disposed with stationary ring, rotating ring along the direction of casing toward pump case and compresses bullet
Spring is provided with the sealed groove for accommodating stationary ring on cover, is provided with the first sealant on stationary ring outer wall, on the first sealant outer wall
It is provided with locking groove, locks and is provided with retaining ring on groove, the second sealant, holddown spring are provided between stationary ring and rotating ring
One end is connected with exporting axis, and the other end is connect with rotating ring.
Through the above technical solutions, when immersible pump be put into hydraulic pressure it is biggish place when, holddown spring to rotating ring apply be directed toward
The pressure of stationary ring, so that the second sealant is close to stationary ring and rotating ring, when output shaft rotates, holddown spring and rotating ring
It can be rotated with output shaft, to apply the pressure for being directed toward casing to stationary ring, so that stationary ring and the first sealant are tight
Casing is pasted, the setting of retaining ring is so that the first sealant and stationary ring close contact, prevent the first sealant and stationary ring from occurring opposite
Sliding, influences sealing effect.
Preferably, restraining position ring block is arranged far from one end of rotating ring in holddown spring, and it is recessed that limit is provided on output shaft
Slot, stop collar are set in limiting groove, and damping groove is provided on stop collar, is provided with damping spring in damping groove.
Through the above technical solutions, stop collar is arranged to limit the movement of holddown spring.When shaking, holddown spring meeting
It shakes, if holddown spring can help stationary ring and first seal to compress to casing toward the vibration of the direction of rotating ring, but such as
Fruit holddown spring shakes toward the direction far from rotating ring, it is possible to pulling force is generated to the second rotating ring, so that rotating ring is close with second
Gap is generated between sealing, influences sealing effect, thus restraining position ring block is set to prevent holddown spring toward separate on output shaft
The direction of second rotating ring is mobile, and holddown spring can compress stop collar toward the direction movement far from the second rotating ring, and stop collar is on the one hand
Holddown spring is prevented to continue mobile toward the direction far from the second rotating ring, another aspect holddown spring can enter the damping in stop collar
Groove is contacted with damping spring, and damping spring absorbs the portion of energy of holddown spring, prevents holddown spring from generating to the second rotating ring
Pulling force ensure that the immersible pump can also have well when shaking so that anti-locating snap ring and second seal generate gap
Sealing effect.
