Q: Why does the centrifugal pump close the pressure to start?: The motor power is selected according to the rated flow of shaft power points plus 15 to 25%, if the outlet valve is fully open to start, the pump flow may deviate from the amount of fixed lot, pump efficiency also reduces a lot, resulting in shaft power greater than the motor power caused by tripping even burned electric machine.

Q: How does the centrifugal pump pump and cut the pump?: Turn on the motor, observe the motor current, turn from high to low, observe the pump outlet pressure, and the pressure rise;Slowly open the outlet valve, so that the pressure drop slowly, the current slowly rising to the stable, the outlet valve to the maximum;Check the pump operation, stuffing box leakage, current, whether or not the rated current, motor, bearing temperature is normal, whether or not abnormal sound.

Q: What are the important parameters of the pump?: Pump parametersFlow rate QFlow is the amount of liquid (volume or mass) that is pumped out in unit timeVolume flow is expressed in Q units: m3/s, m3/h, l/s, etc.

Q: If the suction pump does not have enough suction range, you need to add a vacuum pump to increase the suction stroke. How do you install the suction pipe of the vacuum pump? Water pump impeller is not closed, it is normal that the vacuum pump is unable to pump suction pipe to a vacuum, is it because the water pump outlet pipe connected to the role of the check valve? But the water pump, outlet pipe, check valve sealing performance can achieve the function of non leakage?: Vacuum suction principle of self suction pump:Assuming that the pump connected with the water inlet of a sealed container, the container has plenty of water, since the start of a water pump, water is thrown out of the water impeller pump body, water inlet seal vessel due to the extraction of water to form a vacuum cavity, this assumption will be connected to vacuum cavity and exposed to atmospheric conditions of water, water at atmospheric pressure under the effect of entry into the vacuum chamber".

Q: Water pump can not be pumped out, how to maintain water?: Water pump does not suck or does not drain:The causes for the valve stuck, part of the blockage of water, high water or water leakage is too high, may also turn right, impeller blockage. After checking through them one by one, can be taken at the end of valve repair, clear blockage and correct steering, cleaning and other measures to deal with the impeller.The purpose of the work is to pump water from one place to another, or increase the pressure to control the mechanical energy into fluid energy.

Q: Rules for operation of centrifugal pumps: Working principle and process flowWorking principle: when the drive motor with high-speed rotating impeller, full of fluid in the pump body under the action of centrifugal force, was thrown from the impeller center to the outer edge of the impeller, in this process, the fluid energy, improve the pressure can, at the same time also increases the energy flow rate increase. The liquid from entering the pump impeller shell, the liquid flow gradually widened, the liquid velocity decreased gradually, which will be part of the kinetic energy into pressure energy, which further improves the static pressure of liquid, and liquid with high pressure in pressure pipeline. When the liquid from the leaves out when the impeller center creates pressure and low pressure than the out plane is big, under pressure drive, liquid is continuously from the center of the impeller suction, with the pressure of continuous discharge.

Q: Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?: (three) infusion limited number of pills produced after the dose of obstruction by infusion pump and specification of the matching test, will reach acceptable when the storage pressure of the pressure to determine the alarm blocking. Thus, some have restrictions on the infusion tube blocked after the maximum dose pill may have blocked the trigger before the alarm.

Q: What should be used to pay attention to the use of mechanical pumps?: When opening the pump, first close the outlet valve, lift the pressure, then open the outlet valve again, pay attention to the flow of the motor.

Q: Is vane pump good or gear pump good?: 1) the reversible design of gear pumps can also usually reverse, but reverse after the suction port change, and the pump safety valve does not work; leaf pump is generally not allowed to reverse. 3) the single acting vane pump can be designed to change the eccentric distance by moving the stator at the constant speed, so as to achieve the purpose of variable direction.

Q: Do you have a suction pump higher than 9 meters?: Since the atmospheric pressure has been basically determined, the theoretical suction degree of the pump is more than 10 meters.
