"Q & a series of technical problems of air compressor (four)" refer to: http://www.dg-zhihe.com/cn/newsshow.asp? Id=420

Small make up: centrifugal compressor impeller scaling effects, dynamic balance,need to stop cleaning the impeller, do not stop, ensure the impeller less fouling,method or shutdown without removing the cooler clean impeller?

Chi and Technology Master: compressor impeller scaling and operating environment has a direct relationship, when cleaning the impeller to dismantle the cooler.

Small make up: if the above 0.6BAR separator pressure difference (1BAR limit) should stop to replace the separation core pressure began to decline, or, what is the meaning of this sentence, the separator is a separator oil separator or water?

Chi and Technology Master: separator pressure exceeds 0.6BAR replace the oilseparator must, this is because the machine is to separate the unloading pressure asa constant value, when the pressure exceeds the value, before separation pressure will be higher than the rated pressure above 0.6BAR, the motor will overload andoverload. Described here are the oil and gas separator and non water separator.

Small make up: Excuse me before separation pressure is what mean?

Chi and Technology Master: separation before the pressure is the host of the compressed mixture pressure, oil and gas.

Small make up: safety valve oil separator of screw air compressor on how to check?How to realize the automatic exhaust unit? The minimum pressure valve has whateffect? The intake valve and the exhaust valve is automatically controlled?

Chi and Technology Master: first the safety valve by the local labor supervisiondepartments detection; gas solenoid valve energized deflation; the minimum pressure valve is to maintain system pressure within the prescribed pressure, at the same time,the buffer pressure difference on oil separation element damage.

Small make up: we now have a set of equipment is the production of light on the connector, but the final procedure is blown to the surface of the water to air dryingeffect. We have a domestic screw air compressor, after treatment with a freeze dryerand three pieces of "DH" filter. We have checked the Commission places are not the problem, but the effect is not up to the standard of the. Surface dust. Testingstandard is the electron microscope observation of surface 200 times, no foreign body.

Chi and Technology Master: you mentioned the problem very well, which are often neglected problem. Usually the particle filter with the precision filter can remove 0.01 micron particles. But because of the traditional steel pipe in high pressure impact,surface impurities off. If there is a small amount of water. The pipeline, pipe will be eroded, so pipeline dust surprising. If choose Ingersoll Rand super pipeline, these problems can be solved effectively.

Small make up: recently the machine when running the turbine exhaust pressurecontinues to rise, 0.75 machine to 0.8-0.9MPa but also loading and unloading, this is how to return a responsibility / regulation after the pressure switch. The normal period of time again and again.

Chi and Technology Master: analysis from the expensive unit machine, pressure switch compressor settings appear to drift. Through adjusting, vibration and drift is apressure switch locking problem. Replacing device can solve the.

Small make up: two are air compressor Ingersoll Rand, and cooled by cooling waterthe same but the two air compressor exhaust temperature difference. , is this why?

Chi and master the technology: according to your description, we speculate, 1)differential cooling effect of the cooler, such as cooler internal fouling; 2) the machineload, if the two machine pressure difference will impact the exhaust temperature; 3)machine pipe connection, suitable for different working conditions, Ingersoll machinepipe connection adjustable, controlled by valves, or in series or in parallel; 3) your company pipe layout, if the series connection will cause the machine temperature is not a.

Small make up: the wind cooler exhaust temperature high alarm shutdown, according to "show" the exhaust temperature is 110 , is excuse me this kind of circumstanceshould be how to deal with?

Chi and Technology Master: can inspect the exhaust temperature is too high, if highoil check. The cooling system is too dirty; oil is too dirty; if otherwise, to see if there is a problem with temperature sensor

Small make up: ask 16 cubic 20 cubic ship bulk cement tank feeding for what kind ofcompressor???

Chi and master the technology: the use of screw compressor, exhaust quantity will be decided by the conveying speed. Please refer to the relevant information about theproblem.

Small make up: Excuse me, R22, R134a, R404a is a pressure?

Chi and Technology Master: refrigerant pressure is different.

Small make up: centrifugal air compressor (800) greater vibration, the need fordynamic balance, how much is a grade, two grade impeller residual imbalance?

Chi and Technology Master: the dynamic balance weight is less than 50 mg

Reminder.

Chronicles and the electromechanical device limited company to recommend air compressor, water heater, air compressor heat recovery equipment, as long as youhave the air compressor factory, can 0 operation cost of producing hot water andheating.

(this paper mainly analyzes the series of technical problems of air compressor quiz,but in actual in the problem solving process is for reference only.)
