Q: Why should the pump be closed when the centrifugal pump is started?: Therefore to close the outlet valve, the pump during starting output water, the minimum pump power, when the pump reaches the rated speed, slowly open the outlet valve, gradually increase the flow of water, the motor current is gradually increased to the rated current.

Q: What's the pump? Where can I use it?: Working principleIt transfers mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid. Before the pump starts, the pump shell is filled with the liquid to be transported; after starting, the impeller is driven by the shaft to rotate at high speed, and the liquid between the blades must also rotate. Under the influence of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and obtains energy, and leaves the outer edge of the impeller at high speed to enter the volute pump shell. In the spiral case, the liquid slows down due to the gradual enlargement of the flow passage, and the part of kinetic energy is converted to static pressure, and finally flows into the exhaust pipe at higher pressure and is sent to the required place. When the liquid flows from the center of the impeller to the outer edge, a vacuum is formed at the center of the impeller. As the pressure at the upper level of the tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. Visible, as long as the impeller continues to rotate, the liquid will continue to be inhaled and discharged.

Q: Fire control center manually start the fire pump directly, multi line control, called straight up line NHKVV-7*1.5, my understanding is: straight line from fire control center: The vertical line NHKVV-7*1.5 is the remote starting line of fire controller to fire pump room.

Q: How many kinds of pumps are available and the operating principles of various pumps?: There are many kinds. See what divides.According to the working principle can be divided into: the power type pump, also called pump or impeller vane pump, depending on the dynamic effect of the rotation of the impeller on the liquid, the continuous energy transfer to the liquid, the liquid kinetic energy (mainly) and the pressure will increase, then converting kinetic energy into pressure energy through the discharge chamber, and can be divided into centrifugal pump, axial flow pump, partial flow pump and vortex pump etc..

Q: What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?: Displacement of a pump: the volume of the discharged liquid calculated by the change in the size of the sealing geometry for each revolution of the hydraulic pump

Q: Working principle and structure of external gear pump: External gear pump is the most widely used gear pump, the general gear pump usually refers to the external gear pump. Its structure as shown in the diagram, there are mainly driving gear, driven gear, pump body, pump cover and safety valve and so on. The seal space of pump body, pump cover and gear is the workshop of gear pump. The wheel shafts of the two gears are respectively arranged in the bearing holes on the two pump cover, and the driving gear shaft extends out of the pump body and is driven by the motor to rotate. The external gear pump is simple in structure, light in weight, low in cost, reliable in operation and wide in application. When the gear pump works, the driving wheel rotates with the motor and drives the driven wheel to rotate

Q: What are the problems that should be paid attention to when using vacuum pumps?: (14) vacuum pump used in the winter season, after stopping the pump body, lower drain plug unscrew medium on the net. To prevent cracking.(15) the vacuum pump has been disabled for a long time. All the pumps should be taken apart and dried. The rotating parts and the joint should be coated with grease and properly preserved.

Q: When the water pump is started, why should it start when the outlet valve is closed? Thank you: When the valve is closed, the flow of the pump is close to zero, the power of the pump is very small, which reduces the load that the motor starts to bear and has a protective effect on the motor. Therefore, the valve closed to start the pump.

Q: Does the control cabinet of the fire control pump need to be related to the fire control room?: The relationship is simple, the fire pump is pressurized water supply device, the control cabinet is the power supply for the fire pump, the regulator tank is to stabilize the pressure of the network management, reduce the pump frequently start device.

Q: Attention should be paid to the use of pumps?: 1, pump shaft packing completely worn, it is necessary to add 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. 2, the use of pumps in the course of a strong vibration, then must stop to check the reasons, or the same will cause damage to the water pump. 3 gear pump valve Water Leakage, some will use the soil into the water pump inlet tube, the water washed in the end valve, this is indeed undesirable. Because when the dry soil into the inlet pipe, when the pump started working, these dry soil will enter the pump, which will damage the pump impeller and bearings, which shorten the service life of the pump. When the valve Water Leakage must take to repair, if it is serious that it is necessary to replace the new. 4 after the use of pumps must pay attention to maintenance, for example, when the pump is exhausted, we should put the water pump who put clean, it is best to remove the water pipe, and then rinse with water. 5 water pump on the tape should also be written down, and then always flush, and then light out to dry, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.
