They are used for transferring condensate water from the condensator or the turbogenerator of 750~3000KW in power station as well as turbogenerator other liquid which is physically and chemically similar to water. The temperature of the liquid is below 80℃. Inlet pressure is not allowed more than 0.6Mpa.

Performance range
Capacity Q: 11~120m³/h
Head H: 12~143m
Construction
Type NB,NBA, GN, N pumps are horizontal type and GNL pump is vertical type. The pumps use rolling bearings which get lubricated with grease. The shaft seal is either paking seal or mechanical seal.
The direction of rotation
The rotation of the pump rotor is counter clockwise looking from the motor to the pump.

Q: What is a water pump coupling device?: Advantages of water pump coupling device:1. automatic coupling device, easy installation and maintenance. In the absence of automatic coupling device, fixed installation, such as water pump failure, maintenance personnel need to unscrew screws, lifting pumps for maintenance, or with other small pumps pumping water perfect maintenance,If the water is dirty, it is difficult for people to get down, when the inspection and repair encountered great difficulties. But it is equipped with GAK submersible sewage pumpAfter the automatic coupling device needs lifting, the person can directly lift the water pump without the need to screw the screw into the waterAfter graduation, down the guide rail, you can realize the sealing of water pump and pipeline, so as to make the pump run normally. Small sewage pumps are freeInstallation, large sewage pumps are generally equipped with automatic coupling device, automatic installation, installation and maintenance is very convenient.

Q: Must the water pump in the tank be all soaked in water?: Of course, if the motor is overheated, it will burn, and the temperature of the water will drop down.

Q: What is the dry running protector of screw pump? What's the principle and function? Thank you: Principles are generally temperature sensing, such as: when the screw pump by air, the stator and rotor will be heated due to friction,

Q: Water pump outlet valve sequence: To reduce the impact of vibration, noise and vibration on the valve, the soft connection is best at the pump outlet.The check valve is sometimes checked, so it is placed in front of the outlet valve so that the water can be checked out. I think the order should be: pump outlet, soft connection, check valve, gate valve (butterfly valve)

Q: What's the difference between non negative pressure and variable frequency water pump?: No negative pressure is superposed pressure intelligent frequency conversion equipment, pump frequency operation is no negative pressure difference, and the variable frequency pump, variable frequency pump is advanced municipal tap water tank or pool, pump from the tank or pond water pressure to set pressure to the pressure water supply, and no negative pressure directly from water the municipal pipeline, using the original municipal 2~3 kilograms of pressure

Q: Water pump does not produce water, what are the reasons?: 1 check whether the motor is reversed.2, to see whether the export, the entrance blocked, the outlet pressure gauge whether there is pressure.3, whether the pump selection is wrong, you can not suck up the water.

Q: Working principle and structure of external gear pump: When the meshing teeth on one side of the suction chamber are gradually separated, the volume of the suction chamber is increased, and the pressure is lowered, and the liquid in the suction pipe is sucked into the pump; the suction liquid is divided into two parts to be pushed into the discharge chamber by the gear in the alveolus. When the liquid enters the exhaust chamber, the liquid is squeezed and discharged from the exhaust chamber into the discharge pipe because the teeth of the two gears are continuously engaged. The driving gear and the driven gear keep rotating, and the pump can continuously inhale and discharge the liquid. The pump body is equipped with a safety valve, when the discharge pressure exceeds the required pressure, the delivery liquid can automatically open the safety valve, so that the high-pressure liquid returns to the suction pipe.

Q: Hydraulic pump displacement refers to the pump shaft what?: Just as you carry a spoon to the water. How much water can you pump at once (every turn)? That's the displacement.

Q: What is the cause of the damage of pump bearings?: Is the water pump motor overheating or damaged leaves overheating, resulting in overheating bearings, lubricating oil dry, excessive wear and tear guide system damage

Q: What is the difference between centrifugal pump and self suction pump? Which is better?: Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. The centrifugal pump drives the water to rotate through the high speed rotating impeller blade, and the water is thrown out so as to achieve the purpose of pumping water. The impeller rotates at high speed, forcing the liquid at the center of the impeller to be removed at high speeds, resulting in a low pressure at the center of the impeller, and the liquid in the lower trough is continuously sucked.
