The choice of the submersible pump before use is very important. Consider the actual situation of the water source, working time, pumping volume, etc., and comprehensively determine the model of the submersible pump selected. Just like the requirements of the environment, it is necessary to have a safe and reliable power supply, the drop of the outlet pipe on the water surface of the pool is less than the lift, and the water source is preferably clean. When the submersible pump is in normal use, it will inevitably lead to many unexpected situations. In any case, should the submersible pump be stopped immediately?
1) The submersible pump current is unstable and suddenly exceeds the rated current of the motor.
2) If the insulation resistance of the motor is less than 0.5 megohm, the grid voltage is insufficient and less than 5% of the rated voltage.
3) The amount of water is not normal, the intermittent water is discharged, and the sediment concentration is increased.
4) The fuse is burned out and the water supply line is damaged.
5) The unit has obvious noise and vibration.

A submersible pump is designed to be placed (submerged) in the water or other fluid that is to be removed. Submersible pumps are not all alike. There are different versions of these mechanical devices, used in various applications, including borehole, pool, pond, fountain, well, bilge, and sewage, to name a few.
If these pumps are so popular, then there must be some advantages to using them. What are these advantages?
One advantage to a submersible pump is in the way it is designed. It is designed as a tightly contained unit, with watertight gaskets and seals that keep the liquid out of the housing and internal components. This design ensures that the pump will not leak or short out electrically when submerged.
Besides being tightly sealed and waterproof, there are other advantages of submersible pumps over non-submersible models. One advantage is how it pumps the water. The submersible uses direct pressure to push the fluid through the pipe or hose, rather than using the suction method. Using direct pressure means that the pump can move fluids a greater distance more efficiently than suction devices.
Being self-primed is another advantage over a non-submersible. Other types of pumps, such as jet pumps or shallow well pumps, require being primed to start up. Priming is not required to start a submersible unit.
Also, due to it being placed directly within the liquid, the submersible model can operate more efficiently when moving liquids a long distance.

Is There Any Disadvantage To Using a Submersible Pump?
When considering the advantages of any type of product, one must also look at possible disadvantages. Of course, as with any kind of mechanical device, there is always the risk of some sort of problem occurring.
One potential problem would occur if a gasket were to rupture or lose its integrity. This would cause the pump to leak, eventually corroding the internal components and causing it to fail.
A problem or failure of the pump brings a second disadvantage to light. If the pump does need to be repaired or replaced, it may be more difficult to retrieve, by nature of it being submerged in water.
Another disadvantage is that it may cost more than a comparably sized non-submersible unit. While the price may be a consideration when deciding on a purchase, when weighing the advantages and disadvantages, the submersible pump often wins out.
In conclusion, when looking at the advantages and disadvantages, you will likely come to the conclusion as have many others, that the submersible pump is a convenient and versatile device – useful for many different purposes.

If you have a sump pump in your basement, you are probably very familiar with submersible pumps. Submersible pumps are operated by hermetically sealed motors and are, as their name suggests, used to pump liquid that they are fully submerged in. The pump operates by pushing the liquid it is submerged in up to the surface.
Like in a centrifugal pump, the pump consists primarily of a casing and impeller. The sealed motor drives the impeller to draw water up into the pump, where the force of the spinning impeller against the casing sends the water around and out of the pump and up a pipe or hose to the surface.
Submersible pumps help avoid issues with pump cavitation, where the pump begins to form bubbles of vapor and inhibit correct pump function. Being completely submerged helps prevent this issue from occurring and enables better continued use without interruption.
A sump pump in a basement is not the only place submersible pumps are used. They have many applications, and it is important to understand what your pump needs to be able to handle before purchasing and installing. Among other uses, they are commonly found in water treatment and petroleum applications and are widely used on construction sites and other applications.
One important consideration is the level of solids and the kind of material being pumped. In the future we will discuss how to select a pump for higher levels of solids and heavier liquids.

After assembling the hub of the pump on the shaft, the verticality and concentricity of the hub and the shaft should be carefully checked. Generally, two dial indicators are arranged on the end surface and the outer circumference of the hub. When the disk drive rotates the shaft, the value of the full run-up (including the end runout and the radial runout) of the hub is observed to determine the perpendicularity between the hub and the shaft and the coaxiality Degree of the situation.
Different speeds of the coupling requirements of full beating different, different types of coupling requirements for full beating also vary, but after the assembly of the hub in the shaft, you must make the hub full runout deviation in the Within the design tolerances, this is one of the major quality requirements for coupling assembly.
Submersible pump assembly caused by the wheel full run-out value does not meet the requirements for many reasons, first of all may occur in the manufacturing process due to the error for the field assembly, mainly due to improper handling of the hub hole surface modification, the hub and shaft concentric Degree of deviation. Another reason is that when a keyed shaft coupling is assembled, the hub and the shaft are not coaxial due to incorrect key assembly.
The correct installation of the key should make both sides of the key and the keyway closely fit the wall, usually with the paint color inspection assembly, with the bad file can be used to repair the file or blade to meet the requirements. The upper part of the key generally gap, about 0.1-0.2mm or so. High-speed rotating machinery requires high concentricity between the hub and the shaft. High concentricity can not be obtained by a single-key connection. Concentricity can be improved by using a double-key connection or a spline connection.
