The pump has reasonable structure, high efficiency, high gas etching capability, low shake, operational balance long service life, etc. It can feed clean water or clean water like liquid with physical and chemical property with a temperature of below 80℃ . It is the ideal mine drainage and high pressure water supply equipment and is applicable to the fields of petroleum, chemical, metallurgy and factory and urban water supply and drainage, etc.

Currently our factory mainly produces SGD80, SDG150 and SDG200 type products.

Operation Parameter

1. Flux:100～420 m³/h
2. Lift:99～1124 m
3. Power:55～1800 kw

Q: Fire hydrant pump button, under what circumstances do not need to install?: General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.

Q: What is the pump lift voltage? And how to suppress the pumping voltage rise?: The elevator is mainly used by the power grid through the rectifier, filter, inverter and other transmission to the motor. The motor in high speed when the brake suddenly, but the rotor of the motor with the load (production machinery) mechanical inertia, could not stop quickly, resulting in the back EMF (EU voltage) motor is in the state of power, the reverse voltage and torque original electric state torque instead, and the motor with brake strong torque, forcing the rotor to stop fast but usually AC-DC-AC converter is the main power AC/DC rectifier circuit is irreversible and therefore cannot go back to the grid, energy will be accumulated in the filter capacitor, produce pump voltage, this phenomenon of pump voltage converter has great destructive power.

Q: What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system? How to choose in the project?: Pump control system is generally used for closed systems, the flow of the oil pump changes to control the motor or cylinder actuator action. The utility model has the advantages that the principle is simple, and the power of the engine can be fully utilized. The disadvantage is that the calorific value of larger, relatively poor precision.

Q: Variable flow pumps are variable pumps: Variable input speed, the pump out of the flow is variable, it can not be said that it is variable pump.In a word。 A variable pump is a variable displacement pump.

Q: How to select metering pump head?: In metering fluoride, we recommend the use of Viton, sealed PVC pump head. For most chlorination applications, it is better to use EPDM sealed NP (plexiglass) pump head. For hydrogen peroxide mixtures, only PTFE sealed PTFE pump head or stainless steel pump head can be used

Q: How to install, operate and maintain the pipeline booster pump?: The motor coil is provided with a safety protector, and when the pump is out of order or the water is not pumped, the motor can automatically break down when the temperature of the motor exceeds the prescribed value, and the motor can automatically resume operation after the temperature rise of the motor is decreased. The booster pump motor is a capacitor running type motor. When the pump leaves the factory, the rotation direction has been adjusted. If you need to replace the capacitor or re connect, press the arrow direction on the pump body to mark the connection. To ensure safety, use the three - core safety socket with ground wire.

Q: What does electromechanical vector pump mean?: Commercial buildings: hotels, office buildings, department stores, large saunas, etc.Irrigation: such as parks, playgrounds, orchards, farms, etc.Manufacturing: such as manufacturing, washing equipment, food industry, factories and so on

Q: Which nuclear submarines use the shaftless pump technology?: Shaftless pumping technology and Simulation of shark skin technology are all the next generation of submarine propulsion technology. At present, there is no submarine in the world.

Q: What does "dual purpose" of water pump mean? Please expert advice: In order to ensure safe and continuous operation, three pumps usually need two units and run one standby.Precautions for using pumps1, if there is any small water pump failure, remember not to work. If the pump shaft packing end wear should be added in time, if you continue to use the water pump will leak. The direct effect of this is the increased energy consumption of the motor, which will damage the impeller.

Q: What is the distance between the pump and the wall?: What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.
