Q:What is the lift of diaphragm pump?

Tell you: diaphragm pump head is liquid through the pump energy obtained is called lift it, and flow and pump speed, a liquid density is generally 1 kg is 10 meters lift, horizontal pipeline 10 meters 1 meters lift, a 90 degree bend is 1 meters.

Q:How many kilograms of water pump are there in the automatic washing machine on the market?

Longer service life. Automatic switch water pump, car wash automatically open and stop, easy to operate, not easy to bad, repair rate is low!!!

Q:Why adjust the centrifugal pump outlet valve can adjust the flow? What are the advantages and disadvantages of this method? Is there any other way to regulate the flow of the pump?

The use of frequency converter to adjust the speed of the motor can also adjust the flow, the advantage is to save electricity.

Q:The main factors affecting the performance of centrifugal pumps

The specific speed is deduced by the law of hydraulic similarity, and the similarity between the hydraulic characteristics of centrifugal pumps is similar. In centrifugal pumps, the specific speed is often interpreted as: the pump works at the highest efficiency, generating a lift of LM, a flow rate of 0.075m, and the power consumed by the /s at 0. 735kW

Q:What is the cause of the damage of pump bearings?

In high-speed equipment, the most likely damage to bearings is high temperature.

Q:Why should I pump the pump before starting the centrifugal pump?

Only centrifugal water can be pumped out of the centrifugal blade to generate negative energy at the entrance. There is no water diversion. Only the negative pressure produced by the air is too low to absorb the well water.Water pump has been pumped, centrifugal pump or can not start normally, mostly because of the water pipes and air

Q:If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?

What will happen then? The aquarium glass is an insulator. The water in the fish tank has the same potential as the live wire, and the fish is like a bird standing on the fire line. No electricity flows through their bodies, so they won't get electrocuted. But if you put your hands into the water, you will get an electric shock, because the line voltage through the water, then your body and the earth to form a loop, current flowing through your body you will get (of course, if you stand on the insulator does not get an electric shock)

Q:What are the conditions required for hydraulic pumps to complete oil absorption and compression?

2, the change of working volume is periodic, and in each cycle, the oil absorption process is changed from small to big, and the process of oil pressure is changed from large to small;3, suction oil cavity must be separated from each other without interference.

Q:How long does the fine stone pump need maintenance? What should I pay attention to?

nan

Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system? How to choose in the project?

Valve control system is generally used for open systems, through the proportional valve or servo valve flow changes to control the motor or cylinder actuator action. The advantages of the system are energy saving, heat generation, and control accuracy. The disadvantage is that the system is complex and the cost is higher.
