Q: Why does the centrifugal pump close the pressure to start?: Therefore, the operation rules of multistage centrifugal pumps require that the inlet valve be opened before opening, and the outlet valve is closed. However, the export valve closed time can not be too long, because at this time the medium in the pump cycle, the medium temperature gradually increased, easy to cause mechanical seals, due to lack of lubrication friction and wear or damage.

Q: What is the minimum continuous flow of a pump?: The minimum continuous steady flow can be obtained by test and, in general, the pump supplier will indicate(2) minimum continuous heat limited flow (.API) provides minimum continuous heat limit flow, which means the minimum continuous flow that the pump can maintain and that its operation is not impaired by the temperature rise of the liquid being pumpedMinimum continuous heat limited flow can be calculatedIn the formula, the Pe amount of the fixed axis power is.KW;P pump medium density, kg / m3;

Q: The difference between diaphragm pumps, vacuum pumps and centrifugal pumps: The function of vacuum pump is to make vacuum, which has many kinds of structure, such as centrifugal, diaphragm (diaphragm), piston, liquid ring, rotary plate, jet type...................

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 line between the fire pump buttons should be NHBVR-4*1.5 lines. 2 start, 2 answer. Some manufacturers reported that the 3 lines can also, this need to see which is the specific equipment. In addition, we need to introduce 2 warning buses.The above lines are individually distributed

Q: Operating procedures for measuring pumps: start-up1. Adjust the stroke indication to zero by adjusting the nut or handle with the rotary stroke.2 open the outlet valve.3. Open the inlet valve, pump, exhaust from the high point, exhaust from the relief valve, the breather valve.4, point motor, check the operation of the pump.5. Start the motor.6, without pressure on the premise, every 15 minutes to improve the stroke 20%, if there is no pressure, do not substantially improve the stroke.Note: (1) whether the sound or vibration of the pump is abnormal (2), whether the stroke adjustment is automatic or not

Q: Water pump does not produce water, what are the reasons?: The reason why centrifugal pump does not produce water:1. pump inlet or sink, water tank water shortage.2. water pump pipe blocked or valve not open.

Q: How high can the pneumatic diaphragm pump be?: If the pump material made of polypropylene (PP) material, corrosion resistance, good chemical resistance using PP material produced by pneumatic diaphragm pump can resist medium low cost, good generality, polypropylene material mainly is especially suitable for general acid-base liquid, using poly propylene made of plastic gas diaphragm pump can only withstand the highest temperature to 65 degrees, more than this number of polypropylene plastic deformation.

Q: What is the difference between the ground pump and the pump in the commercial concrete?: Day pump: the pump and pipe will be placed in a position on the site, the pipe in the air like the crane arm

Q: What is the difference between an air pump and a water pump?: Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
