Stainless steel deep well submersible pump series, stainless steel casing, joint, pump head, shaft, shaft flower, guide vane, water valve, water outlet, filter, etc. are all made of stainless steel. The thrust bearing is made of composite stainless steel wear-resistant material and never rusts. High quality, longer product life and reduced maintenance and repair costs. The maximum lift can reach 260 meters, the diving depth can reach 350 meters, and the traditional flow can be broken. The 4" submersible pump can reach up to 20m3/h. The impeller is in suspension state during the working period. The axial pressure on the motor is small, and the high lift is used. Longer life. The bedrock drilling can realize small caliber work, which can save you the drilling cost and time obviously. It is equipped with automatic liquid level electric control box, “water full”, “shallow water”, “automatic control of electric pump opening and stopping With perfect precision overload protection, there is no need to worry about damage to the motor during normal use. The motor is lubricated by oil and water lubricated.
Stainless steel deep well submersible pump model:
150QJ, 200QJ, 250QJ, 300QJ, 350QJ, 400QJ.
main feature:
Corrosion-resistant, environmentally friendly, high lift, high flow, oil-filled motor, durable. Scope of application:
Applicable to mining, factories, buildings, deep well water, chemical liquids, medicine, food processing and other applications.
installation method:
Stainless steel submersible pumps are usually connected by PE pipes, and the joints are connected by flanges or elbows. PE pipe is corrosion resistant and cost effective.
Conditions of Use
1. The medium temperature does not exceed 80 ° C, the density is 1.0-1.3 kg / m & sup3;, the use range of 304 is easy to use between pH 4-10, if it exceeds the medium, it is recommended to use 316.
2. Under normal circumstances, the pump must be used within the range of the lift to ensure that the motor is not overloaded. If it is to be used within the full lift range, it should be specified separately when ordering.
3. The motor current must not exceed the rated current of the motor during operation.
Operation and maintenance
1. When the electric pump is just running, pay attention to monitoring and inspection. If there is no abnormality, it can be put into operation.
2. Every 8h should be inspected once. Pay attention to whether the indicator values of ammeter and pressure gauge have significant changes, whether the operation is stable and the noise is high or low. Pay special attention to the current when the motor is working normally. The current should not exceed the rated value specified on the motor nameplate.
3. When running for more than half a month, if the vehicle is parked, the insulation resistance of the motor should be measured. The value should not be lower than 0.5MΩ (measured immediately after power off).
4. All instruments of protection devices should be inspected on time to ensure their correctness and reliability.
5. When the submersible pump is used under the specified conditions of use, it should be guaranteed to work reliably within one year. For each year of operation or less than one year of operation, but the diving time has reached two years, the electric pump should be lifted from the well for preventive inspection, planned maintenance, cleaning the inside of the motor, and replacing the wearing parts.
6. If any of the following conditions should be stopped immediately:
1) The pump works at the optimum operating point, the voltage is the rated value, and the current is greater than the rated value;
2) When the flow rate is reduced by 20% under the rated head (can also be handled according to user needs);
3) When the insulation resistance is lower than 0.5MΩ;
4) The water pipe has significant vibration and there is a booming noise;
5) The installation and use conditions change, when the conditions of use are exceeded.
