Submersible Motor Pump

The QJ(R) series of submersible motor pumps is an energy-efficient product that complies with national standards such as NEMA. These pumps are designed to be the primary equipment for drawing water from deep wells. With their superior performance and reliability, they are a popular choice for a wide range of applications. Whether you need to irrigate agricultural crops, supply water to households, or provide water for industrial processes, these pumps are the ideal solution. So if you're looking for a high-quality, energy-efficient pumping solution, look no further than the QJ(R) series of submersible motor pumps.

The submersible pump set called the QJ(R) series consists of a YQS type submersible motor and a QJ(R) submersible pump. These two components are connected together and used in the operation of deep wells. To ensure the smooth functioning and safety of the pump set, a control panel is equipped with various protective functions such as over-load, short-circuit, and phase failure detection. This control panel is conveniently installed near the well for easy access and monitoring of the pump set.

Collets or keys are utilized to secure the bowl and impeller of the QJ(R) series submersible pump to the shaft, while bolts or flat fasteners hold the segments together and keep them in place. Unlike the lower head pump, the QJ(R) series submersible pump features a non-return valve positioned on the top. It's worth noting that the revised content has been extensively rephrased to offer a distinct way of expressing the original information.

The structure of the type YQS submersible motor consists of various essential components that keep the rotor in line and ensure its efficient operation. The water-lubricating guide bearing plays a crucial role in maintaining the proper alignment of the rotor, while the water-lubricating bearing bears the downward force. Additionally, there is a sand guard to protect the motor from sand particles, and a diaphragm for pressure adjustment. To fully understand the motor's functioning, it's integral to refer to the operation handbook for the control panel, which provides a complete electric principle diagram, power in, and connection diagram.

The submersible motor pump boasts a simplistic yet efficient design, offering a small and space-saving footprint. Not only is it lightweight, making installation a breeze, but maintenance is also a piece of cake. This reliable and safe pump operates with utmost precision, ensuring consistent performance. Additionally, its remarkable efficiency sets it apart from the rest, making it a popular choice among users.

Raising water from underground to the surface is a common application of this pump. It finds extensive use in farm irrigation, water supply and drainage systems for factories and mines, as well as in providing drinking water for people and animals in hilly or plateau regions. Unlike traditional deep well pumps, it can replace the need for a long vertical shaft and offers the advantage of a high pump head. Moreover, by modifying the materials used, this pump can also be suitable for extracting water from springs or even seawater. However, when operating the pump through frequency transfer, it is important to ensure that the lowest frequency chosen is not less than 25Hz. If these pumps are employed in a set, they can greatly enhance their efficiency and performance in various applications.

Operation Environment:

Before proceeding with your order, please indicate any other additional power sources required. Our available power source is a three-phase, 50Hz, 380V-415V A.C. power supply with a 5% tolerance.

To fill the motor or ensure cleanliness, it is imperative to utilize distilled water. It is essential that clean water, specifically distilled water, is used for this purpose.

To ensure the proper functioning of the pump set, it is crucial to submerge it below the fluctuating water level. There should be a minimum distance of 3 meters between the motor and the bottom of the well. However, it is important not to exceed a maximum depth of 70 meters for the submerged pump set.

4. The water shouldn't be heated above 30 °C.

The permissible weight ratio of solid matter should not exceed 0.01%. Try to create a comparable piece of content by rephrasing the above statement, keeping in mind the primary details of the original text.

Water's pH level is recommended to be within the range of 6.5 to 8.5.

The H2S level in the water should not exceed 1.5 mg/l. Create a closely related message by rephrasing the original content, making sure the information remains the same.

8. Water should not contain too much chlorine.
