Problems solved by technology
[0006] However, since the rotor structure 12 performs balancing work alone, after it is assembled with the cover body 11, the cover body 11 will cause the whole pump 1 to still have residual unbalance.
If the rotor structure 12 and the cover body 11 need to be balanced again, the cover body 11 and the rotor structure 12 must be disassembled before the balance pin 13 can be inserted, so that the balance operation of the rotor structure 12 cannot be completed at one time, and due to the balance The pin 13 is not easy to take out and re-balance. If the balance pin 13 needs to be taken out, the cover 11 and the rotor structure 12 must be disassembled first, so that the cover 11 is therefore scrapped and cannot be reused. It needs to be replaced by another cover, thus improving production cost
Furthermore, the complete blade formed by the first half blade 111 of the cover body 11 and the second half blade 121 of the rotor structure 12 will have an assembled seam on the pressure surface (that is, the water drawing surface), which will also affect the time of drawing water. water flow, thereby reducing the efficiency of pump 1

Description
technical field [0001] The invention relates to a pump and its balance cover, in particular to a pump and its balance cover capable of repeatedly adjusting the amount of rotation balance. Background technique [0002] Pumps, such as water pumps, are used to draw water and move water from a low level to a high level through the pump. Therefore, pumps are widely used in daily life, including water storage in building water towers and pumping of stagnant water. [0003] The basic requirement of a pump is a good water-drawing efficiency. Taking the design of a centrifugal pump as an example, it drives the blades to pressurize the fluid and discharge it from the outlet through the appropriate speed of the rotor structure to achieve the predetermined lift and flow (that is, the amount of water drawn) ). The rotation balance of the rotor structure itself will directly affect the force, vibration and life of the pump shaft, so the design of the rotor structure is particularly impor...
