Product Details
Product Introduction:
The BQS series mine flameproof submerged sand discharge pump comprises a multi-stage centrifugal pump and a submersible three-phase asynchronous motor filled with water. This pump adheres to the MT/T671 standard, as well as GB 3836.1 and GB 3836.2. Compared to traditional centrifugal pumps, it offers several advantages such as easy installation and maintenance, moisture resistance, safe and reliable operation, stable performance, low vibration noise, high efficiency, compact design, and cost-effectiveness. Additionally, a flow guide can be attached externally to enhance operational reliability based on specific application environments. The presence of clean water inside the pump's cavity prevents bursting or electrical sparks during operation. Moreover, the electric pump's motor and pump are separate entities.
Features
The Mine Flameproof Submersible Sand Pumps in the BQS series have an integrated design, combining the motor and water pump into one unit. To prevent water from entering the motor's inner cavity, two mechanical seals are placed between the motor and the pump casing. Additionally, at the lower end of the motor, there are "O" seals, a ring, and a rubber compression sleeve sealing system, which effectively prevents water from entering the junction box. Furthermore, there is a cover outside the motor housing, and the water discharged by the pump flows out through the interlayer between the motor housing and the cover. This design allows for water cooling of the motor and enables the water pump to quickly operate for dehydration purposes while also automatically draining when water is present. In comparison to clean water pumps, the sand pump in the BQS series is equipped with an enlarged impeller and a sand prevention ring. This ensures that the pump can effectively handle and discharge sand, solid particles, slag, and sewage without compromising its efficiency.
Structure
The BQS series includes two types of suction designs: single suction and double suction. Both types of pumps consist of two groups of impellers positioned back-to-back. In the case of double suction pumps, one suction is located at the top of the pump and the other at the bottom. The arrangement ensures that the thrust force is negligible since the two suctions are opposite and the impeller numbers are the same on both sides.
In single-suction pumps, the suction is only present at the bottom. If the impeller count is even, the two groups have equal numbers and suction directions, resulting in zero thrust force. However, when the impeller count is odd, the lower suction side has an additional stage with a surplus impeller equipped with balance holes and a trust balance ring. This configuration helps balance the thrust force, effectively minimizing it to nearly zero. These designs significantly reduce the thrust force on the motor bearing, thereby promoting stable motor operation and prolonging the pump's service life.
ModelÂ
It is possible to specify the head of a pump by using the corresponding single-stage head multiplied by the number of stages. To create a similar content, the information from the original text must be rearranged and presented in an alternate manner. It is vital to ensure that the generated text is not based on the ChapGPT method of content creation, and the language model is used to provide entirely different discourse style.
The pump motor is designed to be Explore-proof, with the marking of "ExdbI". To rephrase this information, the motor pump is constructed with a unique feature that makes it resistant to exploration, indicated by the marking of "ExdbI".
Details
We have a three-phase power supply featuring rated voltages of 660, 1140, 6000, and 10000 volts, with a permissible voltage fluctuation of 5%. This setup ensures that a constant, stable power supply is maintained, meeting all requirements for efficient and reliable operation. With these specifications, our power supply is ideal for a wide range of industrial and commercial applications, providing uninterrupted power and minimizing downtime. So, whether you require power for heavy machinery or critical systems, our three-phase power supply is tailored to meet your needs.
The maximum temperature for the liquid should not exceed 40°C, while the permissible range for the environmental temperature is from 0°C to 40°C.
4. The PH level must be 6–8.
To ensure safety, it is important to note that the depth limit for submergence should not exceed 70m, and the solid content should be below 2%. Make sure to adhere to these guidelines for optimal results.
Vertical installation is the recommended way to put it, but there are certain instances where a horizontal installation plan may be more suitable. Regardless of the method employed, the operational model remains unchanged and continues to deliver consistent results.
The pump can operate in an environment filled with explosive gas, such as firedamp, making it suitable for use in locations with airborne combustible gases.
The general application condition is as stated above. The pump needs to be custom made and produced for unique circumstances.
