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 maintain and repair the booster pump of pipeline pump?
Two 、 troubleshootingfaultReasonRemoval method1. water pump does not produce waterThe water injected into the water pump is not enough, the rotation direction is not right, and the impeller passage is blocked.Pump water into the pump, pass through the impeller runner, adjust the direction of rotation.2. pump flow is insufficientThe pump speed is too low, part of the blockage, the total lift pump is higher than the rated value, the damage to the impeller.Clean the water pump and pipe, replace the impeller, increase the pump shaft revolutions, adjust the outlet valve.3. lack of outlet pressureThere is air in the liquid, the speed is too low, the impeller is damaged and the outlet valve is open.Exclude liquid air, increase the pump speed, replace the impeller, adjust the small outlet valve.
Q:Why should the pump be closed when the centrifugal pump is started?
On the other hand, the water on the pipe of the inlet pipe of the pump is stationary before the pump is opened, such as the sudden acceleration, and the water behind it can not keep up, which will cause the pressure of the inlet to drop suddenly and vaporize the water, and the centrifugal pump will be evacuated. (because of the centrifugal pump is rotating centrifugal force generated by the pump, leaf water and steam driven (gas) quality is very light, according to F= Ma, the centrifugal force is small, the pump can not be water sent).
Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
Direct connected pump: pump impeller installed directly on the motor shaft, it looks like a whole, relatively compact, simple installation, but the general power is relatively small (big bad processing connection, but not absolute);Non direct pump: pumps and motors are independent of each other, through the coupling torque transmission, the structure is relatively large, complex installation, to adjust the level / concentricity and so on, the general power is relatively large
Q:Variable flow pumps are variable pumps
To be exact, variable pump means variable displacement. Because if the displacement does not change
Q:Is the vacuum pump air compressor?
No, both work in the opposite way. Air compressor, referred to as an air compressor, is a machine that produces compressed air (positive pressure). The vacuum pump is just the opposite.
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:Water pump does not produce water, what are the reasons?
4. as a water inlet valve, check whether it is normal, whether the silted up.5. the installation height of water pump exceeds the allowable suction height of pump, or the suction pipe is too long.
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:Why adjust the centrifugal pump outlet valve can adjust the flow?
The use of frequency converter to adjust the speed of the motor can also adjust the flow, the advantage is to save electricity.
