The isolating rings 14 are arranged on two sides of the impeller 4, the isolating rings 14 are fixed on the pump shell and have a certain gap with the impeller 4, the flushing water holes are connected with the flushing pipe 3, and water flow in the flushing pipe 3 enters into the capillary flushing holes 19 through the flushing water holes and the flushing water grooves.
Compared with the traditional double-suction pump, the double-suction pump is provided with the flushing water tank and the capillary flushing hole 19, so that the impeller 4 can be effectively cleaned, and the impeller 4 is prevented from being blocked.
Since the impeller 4 rotates during operation, a gap is necessarily formed between the isolating ring 14 and the impeller 4, but the gap between the isolating ring 14 and the impeller 4 is not more than 1mm, and after the gap exceeds 1mm, more water flows back, so that the isolating effect is affected.
Example two
The embodiment is similar to the first embodiment in that the impeller 4 is directly connected with the pump shaft 8 through threads, the axial direction of the impeller 4 is provided with internal threads, the pump shaft 8 is provided with a section of external threads, and the impeller 4 is fixed through the set screw 7 after the position of the impeller 4 is determined.
At present, the impeller 4 is connected in a shaft sleeve connection mode, and components such as a shaft sleeve, a blocking sleeve, a shaft sleeve nut and the like are needed, so that the whole double-suction pump is complex in structure and large in size, and the fault rate is high due to the fact that too many parts are arranged. The impeller 4 and the pump shaft 8 are in threaded connection, so that the connection strength is high, and the impeller 4 can be positioned by fixing the impeller through the set screw 7. Under the condition of the same flow, the volume of the double suction pump can be made smaller, and the failure rate is lower.
Example III
The present invention gives specific examples of the structure of the flush tube 3 portion: the flushing pipe 3 comprises a main pipe and a branch pipe, the main pipe is connected with the branch pipe, and the branch pipe is connected to the pump shell.
Valves are arranged on the main pipeline and the branch pipeline.
The main pipeline comprises a first pipeline and a second pipeline; the branches comprise a first branch, a second branch, a third branch, a fourth branch, a fifth branch and a sixth branch;
the first branch, the second branch and the third branch are connected with a first pipeline, and the fourth branch, the fifth branch and the sixth branch are connected with a second pipeline;

the third mounting platform is positioned at the top of the pump shell, the second mounting platform is positioned between the first mounting platform and the third mounting platform, and the fourth mounting platform is positioned between the third mounting platform and the fifth mounting platform;
The third mounting platform is provided with an exhaust hole, and a pipeline connected with the exhaust hole is provided with an exhaust valve 5;
the second mounting platform and the fourth mounting platform are provided with flushing water holes which are respectively connected with the second branch and the fifth branch; water holes are formed in the first mounting platform and the fifth mounting platform and are respectively connected with the first branch and the sixth branch; and a third branch is fixed on the side wall between the second mounting platform and the third mounting platform, and a fourth branch is fixed on the side wall between the third mounting platform and the fourth mounting platform.
It can be seen that the flushing pipe 3 in the embodiment is more than one way, the upper part of the pump shell is provided with a plurality of flushing pipes 3, and the flushing effect is good when the pump is flushed from top to bottom.
Example IV
The section of the isolating ring 14 is U-shaped, the isolating ring 14 comprises a bottom and two side branch parts, a capillary flushing hole 19 is arranged on the bottom, and a groove is formed in the branch part for installing the O-shaped sealing strip 13; a flushing water tank is formed between the bottom and the branch part. The spacer ring 14 is sealed with the mounting portion of the pump housing by two sealing strips, so that leakage from the high-pressure pump cavity to the low-pressure pump cavity can be controlled, and flushing of the pump housing can be reduced. It should be noted that, since the water flows up and down, the capillary flushing holes 19 are not necessarily provided in the lower portion of the spacer ring 14, and as shown in fig. 3, the capillary flushing holes 19 are provided only in the upper half turn of the spacer ring 14.
Example five
Because the inlet lip edge of the traditional sealing ring is a straight edge, and the sealing ring and the mounting position of the pump housing have no sealing structure, the sealing ring is suitable for common clean water media. According to the invention, the lip edge of the inlet of the isolating ring 14 is a straight edge, and the mounting position of the isolating ring 14 and the pump housing has no sealing structure, so that the efficiency of the pump is affected. The side of the isolating ring 14 is provided with the diffusion lip 11 or a baffle part, as shown in fig. 4, so that the arrangement can reduce the water flow from the extrusion chamber 17 to the suction chamber 18, reduce the influence of the reflux liquid on the suction inlet of the impeller 4 and improve the output efficiency of the pump.
Example six
In order to support the pump shaft 8 and facilitate better rotation of the pump shaft 8, the non-driving end bearing body part 1 and the driving end bearing body part 10 are respectively arranged on two sides of the pump shell; the bearings of the non-driving end bearing body part 1 and the driving end bearing body part 10 are connected with the pump shaft 8; the pump shaft 8 extends out of the bearing body part 10 at the driving end and is provided with a pump coupling on the rotating shaft, and a key slot 9 is arranged on the pump coupling.

The bearing is arranged on the non-driving end bearing body part 1 and the driving end bearing body part 10, the bearing is fixed and then plays a supporting role on the pump shaft 8, and on the other hand, the pump shaft 8 rotates smoothly due to the connection relation between the pump shaft 8 and the bearing, the lost energy is less, and the output of power is facilitated. In order to lubricate the bearing, bearing lubricating oil cavities are arranged in the non-driving end bearing body part 1 and the driving end bearing body part 10, and the bearing is lubricated by the lubricating oil in the bearing lubricating oil 16 cavity.
The driving end bearing body part 10 and the driving end bearing body part 10 are fixed with the pump body 6 through studs, spring gaskets and nuts. Because the non-drive end bearing body part 1 and the drive end bearing body part 10 are arranged outside the pump body 6, and the weight of the non-drive end bearing body part is heavy, the connection strength is higher through the connection mode of the double-head screw, and the long-term use of the non-drive end bearing body part 1 and the drive end bearing body part 10 is ensured.
In general, the water pump is provided with a support, and the pump support is arranged below the pump body 6, and is different in that the pump support comprises 4 pump feet 12, the pump feet 12 are outwards unfolded by the pump shell to form an unfolded support, the upper end is contracted, the lower end is unfolded, the supporting force is good, and meanwhile, compared with the traditional rectangular support, the material can be saved, and the economical efficiency is good; the end of the pump foot 12 is provided with a mounting hole, which is convenient to fix by a bolt. Through bolt (expansion bolts) fixed, simple to operate, and fixed strength is high, avoids long-time vibration back pump support not hard up.
In summary, the upper half circle of the isolating ring 14 is provided with the capillary flushing holes 19, so that flushing water is used for flushing after shutdown when sediment and suspended matters are conveyed and scale medium is easy to deposit, and the blocking phenomenon of the shutdown scale impeller 4 can be prevented. The spacer ring 14 is sealed with two sealing strips at the mounting position of the pump shell, so that leakage from the high-pressure pump cavity to the low-pressure pump cavity can be controlled, and flushing of the pump shell can be reduced. In addition, the diffusion lip 11 of the isolating ring 14 is arranged, so that the loss of fluid in a sealing gap to the inlet of the impeller 4 can be reduced, and the efficiency of the pump can be improved; the diffusion lip 11 is beneficial to slag discharge, and particularly, the sand particles contained in the medium can be conveniently discharged, so that the spacer ring 14 and the impeller 4 are prevented from being worn out due to direct entering into a gap.
The foregoing description of the preferred embodiment of the invention is not intended to be limiting, but rather to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
