Q: What are the internal losses in centrifugal pumps? How did they come about?: Hydraulic loss: the loss of water by friction, eddy, impact, etc in a flow;

Q: The function of centrifugal pump: 6. Stuffing box mainly consists of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump! When the pump shaft and packing friction heat, it is necessary to rely on water seal to control water into the water ring, so that the filler cooling! Keep the pump running properly. Therefore, in the water pump running inspection process, the stuffing box inspection is to pay special attention to! In the operation of about 600 hours, it is necessary to replace the packing.

Q: What should I pay attention to when buying a pump?: Two, the first choice of large and medium-sized professional manufacturers, and through the quality identification of relevant departments, the market credibility of the better models, but also to the professional quality inspection institutions consultation.Three, check the motor grounding device for electric pump, water pump and motor axis, the motor should be in a proper position is provided with a grounding screw, and the grounding screw are arranged near the ground; grounding device of small submersible pump should be reliable and grounding wire, grounding wire cables should have the obvious grounding mark the flag should be in use; the motor is not easy to be worn during the period. This is one of the important safety indexes of electric pumps.

Q: What does "anti pump" mean in pump operation?: The working process of the main oil cylinder pushing back and forth against the pump when the S valve (C valve or valve or gate valve skirt) reverse swing, so the piston suction concrete cylinder is in the ash conveying pipe is exactly opposite is the pump suction pump (hopper is concrete and push into the hopper, the desizing)

Q: What does "efficiency" mean in a water pump catalog?: Pump efficiency: the ratio of the effective power and the pump shaft power

Q: Please give me professionals to calculate, the cylinder bore is 100 and the rate of 20m/s, the leakage can be ignored, but to the large flow pump!: 3. efficiencyVolume efficiency, for hydraulic pumps, is the ratio of actual flow to theoretical flow. A hydraulic motor is the ratio of its theoretical flow to its actual flow.Mechanical efficiency, for hydraulic pumps, refers to the ratio of theoretical torque to actual input torque. The actual output torque of the hydraulic motor is theoretical torque to overcome the torque after friction, so the mechanical efficiency is the ratio of the actual output torque to the theoretical torque.

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?: (1) the pellet dose in the safety standard of the infusion pump refers to the amount of liquid that is transported to the patient in a short period of time(two) pill dose limit is mainly to control the risk of accidental pill dosage. Especially after the mandatory requirements of pipe blockage in the elastic pipe storage liquid limit amount of agglomeration and the limitation of these methods to release pill dose.

Q: What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?: The unified corrosion resistant design of bronze impeller improves the corrosion resistance of the pump, and the stainless steel material is more suitable for more severe applications;

Q: Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?: Start the pump. Water pressure depends on how large you buy the pump, generally small, mostly 10-15 meters hydraulic pressure, about 200 of the price.

Q: No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?: Non negative pressure variable frequency water supply means no negative pressure superposed water supply equipment. When running, it is connected directly to the water supply pipe. Always test the pressure of tap water pipe network and water supply pipe network pressure control system, when the water pressure is lower than the pressure required by the user, the frequency conversion device based on water automatically control the pump speed through the steady flow compensator of water balance, maintain a constant pressure water supply. In the multi pump system, the control system can automatically dispatch the water pump according to the water consumption. It can balance the working time of the pump and ensure the pressure of the water supply. When the water supply pressure satisfy the required pressure, the system automatically stops the pump by the external water supply pipe network directly.
