how to do about submersible sump pump motor water?

Submersible sump pump motor system is the power system of the entire device for the operation of submersible sump pump to provide power support, while the working environment of submersible sump pump in the liquid below, compared to the traditional pump, the working environment is more special, On its motor system waterproof performance put forward higher requirements. Once the motor system water, there will be short-circuit unit, or even cause the entire motor burned, affecting the normal fluid transport work, so to strengthen the submersible sump pump motor water fault processing is essential.

Structure Analysis of Motor Seal and Protection Device for Submersible sump Pump

The function of the submersible sump pump sealing system is to maintain the sealing performance of the whole submersible sump pump and protect the motor unit of the submersible sump pump from erosion and destruction of the debris and water. Its main structure is cable sealing, component sealing and bearing sealing, sealing The device has a good mechanical strength, the corrosion of the material has a good resistance, so as to provide a key component of the protective effect. Submersible sump pump with automatic protection device to avoid submersible sump pump at high temperatures for a long time to run. When the operating temperature exceeds the set temperature for a certain period of time, the temperature control overheating protection device will control the motor device to stop running until the winding temperature decreases, and then start the operation. At the same time the probe submersible sump pump has two protection motor, two motors directly connected to the control center of the control cabinet, when the submersible sump pump seal water leakage phenomenon, the water intrusion into the oil chamber closed system, the oil Cavity resistance rapidly decreased, then the submersible sump pump motor leakage protection system will issue an alarm, and automatically remove the submersible sump pump running power, waiting for the next step maintenance and maintenance. Submersible sump pump motor water setting is essential, submersible sump pump can detect the seal of the motor to assess whether the infiltration of water. When the water into the bearing next to the cavity inside the mechanical seal failure will directly lead to floating float position, which touches next to the float switch, and cut off the sump pump running electric device, issued the corresponding alarm signal.

Cause Analysis of Water Intake Failure of Submersible sump Pump

As the submersible sump pump in the water work, a long time running will lead to the submersible sump pump motor seal system failure, resulting in motor water failure occurred. The following detailed analysis of submersible sump pump motor water failure causes:

2.1 cable breakage

Cable damage is the main cause of motor water failure, due to the installation of submersible sump pump steel cages of the way, the installation is complete, the distance between the submersible sump pump and the covers have a longer distance, in order to provide the sump pump Electric power and power, you need to use cable underwater installation, submersible sump pump cable fixed to the chain hanging down to the bottom of the submersible sump pump, the chain with a flange hook to be fixed, but this fixed way will lead to chains Of the tension is difficult to control, while the quality of heavy cable, when the submersible sump pump running, the cables and chains will be friction, resulting in damage to the cable insulation, water will enter the submersible pump through the cable pump motor , Serious will cause the submerged sump pump burned.

2.2 integrated protection cabinet improper protection

Submersible sump pump is divided into different structures, in the upper part of the submersible sump pump is the wiring room, wiring room at the bottom of the groove is set up a water tank, while installing a floating switch, when the water into the wiring room, it will Directly back to the stagnant tank, the tank height of the water will rise to trigger a floating alarm switch, the motor water alarm signal, which plays a protective role for the motor. But some of the submersible sump pump wiring room float switch height is set properly, the height of water is not enough to inspire the alarm device, but the water will cause the entire electrical system short circuit, or even burn.

2.3 submersible sump pump seal damage

Submersible sump pump for a long time in the water, while its transport medium is more complex, which increases the probability of damage to its sealing device, when the suspended matter in the water medium more, or its corrosive strong, long Time to run will cause serious damage to the pump seal layer, causing leaking phenomenon. Moreover, more sediment in the water, the submersible sump pump impeller fouling serious, the motor bearing load increases, the bearing and box outside the skeleton oil seal between the friction increases, resulting in the phenomenon of water intrusion. In addition, submersible sump pump seal installation is not correct or improper installation of the selection will result in reduced seal life of the seal to accelerate its damage.

3 submersible sump pump motor failure water treatment

Submersible sump pump motor water will cause the operation of submersible sump pump failure, if the submersible sump pump internal water supply alarm system failure, it will lead to submersible sump pump motor burned, the following detailed analysis of submersible sump pump motor water failure Approach:

3.1 improve the submersible sump pump cable fixation

Submersible sump pump fixed way often used iron chain bundled way, but this fixed way affects the life of the cable and the use of stability, thus reducing the wear and tear of the cable insulation is essential. The current cable fixed through the use of pipe mode, the use of galvanized pipe as a cable laying, for example, a submersible sump pump cable set, the use of cable clamp fixed method, according to the use of submersible sump pump on-site conditions, to produce a can open and close Of the cable fixture, and welding the corresponding fixture fixed mold, the cable directly through the galvanized pipe fixture into the submersible sump pump, the fixed mode to improve the stability of the cable, while its simple structure, possession of the Space is small, to improve the protection of the cable, reducing the degree of wear and tear of the cable.

3.2 submersible sump pump seal inspection and replacement

Submersible sump pump seal is the key to avoid motor water, so to strengthen the submersible sump pump sealing inspection, the use of submersible sump pump will cause a long time to reduce the elasticity of the phenomenon, to strengthen the quality of sealing ring inspection, timely Replace the seals with quality problems. Especially in the work environment is more harsh water quality, to strengthen the mechanical seal components of the inspection frequency, for the occurrence of more frequent water alarm key parts, to focus on the sealing inspection. When the sealing coil of the submersible sump pump wears out, it can be exchanged directly. If the elastic spring of the fastening spring is reduced, it should be replaced with the same type of spring and fixed with wire. Moreover, in the replacement of sealing applications, should be used asbestos rope twine, and compacting its bolt fixed to improve the seal sealing performance, to avoid motor water failure.

3.3 timely replacement of submersible sump pump leakage protection components

When the submersible sump pump failure occurs when the motor water, it is necessary to cut off the motor power, to avoid further damage to the submersible sump pump, timely replacement of submersible sump pump leakage protection components to improve the detection of leakage signal accuracy. Float switch sensitivity is not high likely to cause serious water leakage tank wiring compartment, while susceptible to oily substance stuck, loss of detection, it is necessary to use a more simple structure, the higher the sensitivity of the water leakage probe, the leak detection probe has a higher detection sensitivity , Even if the trace of water into, you can also send an alarm signal in time, and cut off the power to avoid submersible sump pump by greater structural damage.

3.4 to strengthen the handling of the transport medium

The transport medium will be submersible sump pump sealing device caused some damage, while different transport medium damage to the submersible sump pump is different from more or more corrosive suspension of the transport medium is likely to cause submersible sump pump motor seal device Damage, so the poor water quality should be properly treated, the correct choice of the type of submersible sump pump to ensure that the motor shaft and the external oil seal installed correctly, to avoid the loss of elasticity of the motor seal leakage caused by the motor. To add the appropriate detergents, regularly clean up the water body of the dirt, and strengthen the monitoring of water quality and maintenance of submersible sump pump work to improve the submersible sump pump motor protection system against water effects.
