Shanghai Zhabei District stainless steel deep well pump product features: The stainless steel deep well pump is a centrifugal or mixed-flow type, using water-lubricated bearings and a rigid coupling to connect the motor to the motor. The impeller of the deep well pump rotates under the driving of the motor to generate centrifugal force, which increases the energy of the liquid and pumps water through the diversion effect of the pump casing. There is a check valve body at the upper end of the water pump to prevent the working parts from being damaged by the backflow of water in the water pump when the electric pump is shut down. There is a drain hole on the valve, which can slowly drain the water in the pipeline to prevent the pipeline from freezing and cracking in winter. (Note: The low-lift submersible pump does not have a check valve body)
The motor of the stainless steel deep well pump is a closed water-filled wet structure. The motor stator winding uses water-resistant polyethylene insulation and nylon sheathed multi-layer electromagnetic wires. Both guide bearings and thrust bearings are made of water-lubricated materials. The inside of the motor is filled with clean water to cool the motor and lubricate the bearings. A pressure-regulating membrane is installed at the bottom of the motor to adjust the expansion-contraction pressure difference of the clean water in the body caused by the temperature rise of the motor. The upper shaft of the motor is equipped with a sand prevention mechanism to prevent mud and sand in the water from entering the body.
The pipeline part of the stainless steel deep well pump: used to connect the electric pump to be hoisted in the well and transport water to the ground. It is mainly composed of short water pipes, water pipes, elbows, splints and other components. The short output pipe is the transitional component between the water pipeline and the electric pump. The elbow is installed at the wellhead to change the direction of water flow. The plywood is used to hoist and fix the output pipeline during the installation process of the deep well pump.
Conditions for use of Shanghai Zhabei District stainless steel deep well pump:
． Stainless steel deep well pump power supply requirements:
The rated frequency is Hertz, and the rated voltage at the motor end should be guaranteed to be a three-phase AC power supply of 3+V (special ordering is required if the user voltage is 3V).
The load power of the transformer should not exceed its capacity.
When the transformer is far away from the well, the voltage drop of the transmission line should be considered. For motors with larger power, the distance from the transformer to the wellhead is required to be no more than meters. When it is greater than meters, the transmission line specifications are required to be two levels larger than the distribution cable specifications. , and consider the line voltage drop.
． Water quality requirements:
Generally non-corrosive clean water.
The sand content in the water is not greater than .(mass ratio).
The pH value is in. within the range.
The chloride ion content in the water should not be greater than mg/L.
The hydrogen sulfide content is not greater than. mg/L.
The water temperature should not be higher than ℃.
3. Wellbore requirements:
It should be upright and smooth, with no bulges or well pipe misalignment. The inner diameter of the well should not be smaller than the corresponding machine frame number.
Installation and start-up of stainless steel deep well pump in Zhabei District, Shanghai:
. Inspection and preparation before installation of deep well pump
Check whether the water well meets the conditions for use of this pump, that is, well diameter, verticality and well wall quality As well as static water level, dynamic water level, water inflow volume and water quality conditions, etc. If the conditions of use are not met, corresponding measures must be taken, otherwise the pump cannot be lowered into the well.
Check whether the power supply equipment and power supply lines can ensure the normal operation of the electric pump.
Whether the power supply voltage and frequency meet the usage conditions.
Be familiar with the installation and operating instructions. Newly drilled wells must be flushed and the mud and sand in the water must be removed before the submersible electric pump can be installed.
Check whether the electrical circuits, control and protection devices are reasonable, safe and reliable.
Prepare various installation tools. The erecting tripod and hanging chain (or other lifting tools) must be safe, reliable and easy to use.
The products have obtained various professional certification certificates and customer recognition for their superior performance and excellent quality. Technology is the primary productive force. Continuous technological innovation is the cornerstone of Samsung's progress. Absorbing and digesting outstanding scientific and technological achievements at home and abroad is the key to our success.
