The QJ(R) series presents an energy-efficient solution that complies with NEMA or national standards. These submersible motor pumps serve as the key equipment for extracting water from deep wells.
The QJ(R) series submersible pump set is composed of a QJ(R) submersible pump and a YQS type submersible motor that are paired to function in a deep borehole. A control panel featuring protection against over-load, short-circuits, and phase failure, among other safeguards, supervises the operation of the pump set. Furthermore, a control panel has been established close to the well. To reiterate, the system's features include a QJ(R) submersible pump, a YQS type submersible motor, and a control panel with a wide range of protection features that were carefully selected to ensure smooth and safe pumping.
Collets or keys are utilized to mount the bowl and impeller onto the shaft, while bolts or flat fasteners keep the segments joined and secured. A non-return valve is present on the top of the pump, except for the lower head pump which doesn't require one. To prevent backflow, this valve allows fluid to flow in a single direction.
The type YQS submersible motor features a rotor that is kept in line with the help of a water-lubricating guide bearing. Along with this, there is also a water-lubricating bearing that bears the downward force. To ensure efficient functioning, a sand guard has been installed in the motor. Additionally, the motor also boasts of a diaphragm that aids in pressure adjustment.
For more information regarding the power in and connecting diagrams, as well as the electric principle diagram, please refer to the control panel's operation manual. This will provide greater clarity and understanding of the motor's constituents and functions.
The submersible motor pump boasts impressive features, such as its small size and lightweight design, as well as its straightforward structure that makes installation and maintenance a breeze. Operating with exceptional efficiency, this pump is also highly reliable and safe, offering peace of mind to those who depend on its performance. All in all, the submersible motor pump is an outstanding choice that offers a range of benefits to those who utilize it.
The process of bringing water to the surface from deep underground has several benefits, particularly in agricultural irrigation, water supply and drainage systems for factories and mines, and providing residents and livestock with drinking water in areas of high elevation or undulating terrain. The device that makes this possible is known as a high lift pump, which can reach depths that a long-shaft deep well pump cannot and can be used in a variety of settings, including the ocean and natural springs. If the pump is powered by a frequency converter, it is important to ensure that the minimum frequency is not less than 25Hz. Additionally, if the pump is utilized in open water, a guiding shroud should be installed to improve the motor's cooling performance.
Operation Conditions:
Before placing an order, please indicate if there are any other power sources required in addition to a three-phase, 50Hz, 380V-415V, 5% A.C. power source.
It is recommended to utilize distilled water or pure water when refilling the engine, or for rinsing purposes.
In order to ensure that the pump set is operating efficiently, it is required to be fully immersed beneath the dynamic water level. The distance between the motor of the pump set and the bottom of the well should be a minimum of 3 meters. However, the depth at which the pump set is submerged cannot exceed 70 meters.
4. The water shouldn't be heated above 30 °C.
The proportion of solid matter in weight must not exceed 0.01%. This information can be conveyed using different words and sentence structure while maintaining the same meaning.
Water's pH level should be between 6.5 and 8.5. It is important to maintain this range for various purposes and applications. Keeping the pH within the desired limits ensures the water's quality and compatibility with different substances and organisms. Deviations from this range can have adverse effects on aquatic life and even corrosion on certain materials. Therefore, monitoring and adjusting the pH levels as needed is essential for maintaining a balanced and healthy environment.
The maximum allowable concentration of H2S in water should not exceed 1.5 mg/l.
It is important to keep the chlorine content in water below 400 mg/l.
Please note that the company is capable of delivering submersible pumps that can exceed the mentioned flow rate and head requirements.
If you intend to use a submersible pump in a large pool with a wide diameter, make sure to use a deflector. Be cautious when choosing the type of deflector that will work best for your pool. It's important to note that without a deflector, the pump may not function optimally, so ensure that you select the right one.
At our business, we offer a range of well submersible pumps that are manufactured using various high-quality materials such as stainless steel, nodular cast iron, and other reliable substances. These pumps are designed to meet different requirements and provide efficient performance in pumping water.
To ensure proper functioning and power compatibility, the industry follows certain guidelines for matching the motor with the water pump. For instance, in the case of the 250QJ (R) pump, a yqs200 series motor with the same power of 25kW is used for ideal compatibility. Similarly, for the 300QJ (R) pump, a yqs250 series motor with the same power is recommended, as long as the motor's output remains below 100kW.
By adhering to these guidelines, we can ensure that the motor and water pump are accurately matched, resulting in optimal performance and longevity of the pumping system. Choose our reliable pumps and rest assured that they are designed and paired with suitable motors to meet your specific application needs.
If the customer has special requirements, it can be matched according to the motor model with the same base number. The company has the right to change this manual. If there is any change, it will not be communicated separately.
