Q:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
Generally slightly lower than 0.4MPa, Zai 0.35Mpa or so, if the outlet is blocked, the outlet pressure will equal 0.4MPa
Q:How to select hydraulic pump?
1. rpmOperating speed is the actual rotation speed of a pump (or motor) at work.Rated speed is the maximum speed that can operate normally for a long time under rated pressure. If the pump exceeds the rated speed, the work will cause insufficient oil absorption, vibration and noise, the parts will suffer cavitation damage, life expectancy.Minimum steady speed is the minimum speed allowed for normal motor operation. At this speed, the motor does not appear crawling phenomenon.
Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines?
Unreasonable, easy to produce throttling loss, pressure loss, pressure reduction, easy to cause cavitation
Q:What are the functions of a disposable infusion pump?
This is a very professional question, ha!I only know disposable infusion pumpsAttached: intelligent medical infusion pump and its application
Q:Does vacuum pump oil belong to dangerous goods?
Of flammable substances, but not included in dangerous goods!Does not belong to dangerous goods,
Q:Variable flow pumps are variable pumps
Variable input speed, the pump out of the flow is variable, it can not be said that it is variable pump.In a word。 A variable pump is a variable displacement pump.
Q:How to select the fire pump?
Such as a large pressure of about 10m or about 0.1MPa} because the most unfavorable point fire hydrant requires more than 0.07MPa (7m) and 0.5MPa (50m) is not greater than the pressure, so unless the pump is located in the 50m Valley is still lower than the garage, or add to the valve (or the use of fire hydrant decompression) otherwise, it is 120m lift pump
Q:What are the application areas of pumps?
1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system
Q:What is cavitation, centrifugal pump cavitation phenomenon how to solve?
First, what is cavitation?:When the centrifugal pump shell has air, it produces less centrifugal force because the density of the air is much smaller than the density of the liquid. Thus, suction pressure at the entrance to the top of the tank liquid level and pump is bad enough to the liquid storage tank into the pump, the centrifugal pump self suction capability, the centrifugal pump can not transport liquid, this phenomenon is called "cavitation".When a liquid drops at a certain temperature to the vapor pressure at that temperature, the liquid produces a bubble. The phenomenon of producing bubbles is called cavitation. When the cavitation bubbles, flow to the high pressure, the volume of reduced, so as to burst. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse.
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.
