China Stainless Steel Submersible Pump manufacturers

China Stainless Steel Submersible Pump manufacturers Submersible motor pumps from the QJ(R) series are an example of an energy-saving product that adheres to NEMA or national standards. It is the primary apparatus for extracting water from deep wells. The QJ(R) series submersible pump set includes a YQS type submersible motor and a QJ(R) submersible pump that are coupled together to work in a deep hole. A control panel that has over-load, short-circuit, phase failure, and other protection features controls the pump set. Near the well, a control panel has been installed. The bowl and impeller are mounted to the shaft by collets or keys, and the segments are joined and held in place by bolts or flat fasteners. A non-return valve is installed on top of the pump (there is no non-return valve for the lower head pump); The rotor is kept in line by a water-lubricating guide bearing, a water-lubricating bearing bears the downward force, a sand guard is installed, and a diaphragm for pressure adjustment is part of the structure of the type YQS submersible motor. See the control panel's operation manual for more information on the power in and connecting diagrams and the electric principle diagram. Outstanding features of this submersible motor pump include simple structure, small size, lightweight, convenient to install and maintain, reliable and safe operation, high efficiency, etc. By bringing water from beneath to the surface, it is frequently utilized in farm irrigation, water supply-drainage systems for factories and mines, and providing people and animals with drinking water in plateau or hilly locations. It has a high head that a long shaft deep well pump cannot reach and can replace a long shaft deep well pump. By altering the material, this pump can also be utilized for spring and in seawater. The set lowest frequency should not be less than 25Hz if the pump set is controlled by frequency transfer. A guiding shroud for the motor should be finished if the pump set is operated in open water to enhance the motor's cooling condition. Operation Conditions: 1. Three-phase, 50Hz, 380V-415V, 5%, A.C. power source. Prior to ordering, please specify any additional power sources. 2. Distilled water ought to be used to fill the motor (or clean water). 3. The pump set must be immersed beneath the dynamic water level, with a minimum of 3 meters separating the motor from the well's bottom. However, the pump set's submerged depth cannot go deeper than 70 meters. 4. The water shouldn't be heated above 30 掳C. 5. The weight ratio of solid stuff shouldn't be higher than 0.01%. 6. Water's PH level should range from 6.5 to 8.5. 7. There shouldn't be more than 1.5 mg/l of H2S in the water. 8. The chlorine content of water should not exceed 400 mg/l. Remarks: 1. The company can provide well submersible pumps exceeding the above flow and head. 2. When the submersible pump is used in large diameter (pool), it needs to add a deflector. Please pay attention to it when selecting the type. 3. The business offers well submersible pumps manufactured of different stainless steels, nodular cast iron, and other materials. 4. The following fundamental guidelines are used by the industry to match the motor and water pump power: (1) The matching motor is a yqs200 series motor with the same power when the matching motor power of the 250QJ (R) pump is s25kw. (2) The supporting motor for a 300qj (R) pump is a yqs250 series motor with the same power when the supporting motor's output is less than 100kW. 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.China Stainless Steel Submersible Pump manufacturers website:http://www.lutsee-pumps.com/submersible-pump/stainless-steel-submersible-pump/
