I am now working for LNG receiving terminal. This is the first time I contact with it. I am interested in LNG pump and motor.I know that the torque and current of motor in cryogenic condition is much lower than the that of motor in normal condition.I also know that is beacause of the cryogenic...
For centrifugal pump,to ensure the motor accelerating the pump to rated speed, the requirement of motor torque should always be higher than the pump load torque.
1. Is there any body know how to calculate the pump load with diffirent rotating speed?
2.normally, pump manuafacture provide us the...
In one project,we used one fire water pump with capacity about 350m3/h, 120mlc, the power rate of the motor is 220Kw,the discharge pipe diameter is DN300. The check valve between the pump is about 2meter. The pump is under the water line, so the piping between the check valve is full of water...
I have met a big problem with the double screw pumps(total no. is 6) in ship(150,000DWT). Each pump rated capacity is 400m3/h, rated discharge pressure is 1200kpa. Rated voltage for the motor is 6300V. The pumps are used to pumping produced water which temperature is about 60centi-degree. The...
