"Q & a series of technical problems of air compressor (a)" refer to: http://www.dg-zhihe.com/cn/newsshow.asp? Id=417

Small make up: the need for periodic blowdown air compressor which devices?

Chi and Technology Master: intermediate cooler, after cooler, gas tank, cold and dry machine.

Small make up: the minimum pressure valve has what effect?

Chi and Technology Master: the minimum pressure valve generally has two functions.The minimum pressure valve one of its role is to buffer, when the machine is in the moment of loading, we assume that the emissions into the atmosphere, high pressure generation and after separating machine internal separation before the difference will all add in the separator, the separator core damage; second is because the machineoil lubrication is to rely on the machine itself pressure difference is, no oil pump auxiliary additional, when the machine is in the idle state, still need a certain pressureto maintain the oil circulation, so the intake valves are relatively close, while theminimum pressure valve to prevent pressure leakage, which can ensure thelubrication oil circulation.

Small make up: what is the role of gas dynamic plastic head piston air outlet? Canthen export add hydraulic oil lubrication?

Chi and Technology Master: This refers to the control cylinder? The plastic head justas cover, to prevent the entry of dust, and the hole as gas use. Add lubricant is not great.

Small make up: what is the role of temperature control valve? What are the roles in the system?

Chi and Technology Master: the role of temperature control valve is adjusting the injection temperature. The oil separator after separation, liquid coolant loop, the oil filter, when the oil temperature is low, the temperature control valve does not move,the coolant to small cycle, if the temperature, temperature control valve open and gradually shutting down small cycle, and make the coolant through the heat exchanger for cooling, commonly known as the big circulation.

Small make up: the cause of pump bearing temperature is high?

Chi and technology teacher: 1) low oil level or lack of lubricant, 2) oily unqualified, 3)bearing defective or damaged, 4) bearing cooling water not vote or interrupt.

Small make up: when the unit exhaust pressure is too low, how can lead tocompressed air oil quantity?

Chi and Technology Master: volume type air compressor in the rated pressure, the machine is working under the rated flow. If lower than the rated pressure, the flow will be greater than the rated flow, so that the oil separation flow will also increase, this is the effect of oil separation variation.

Small make up: Why are some factories use ash air compressor sometimes at run time will automatically uninstall or even shutdown, fuel inlet outward, often the intakehose hot breaking.

Chi and Technology Master: this situation should first check the oil cut-off valve andcheck valve with what did not appear abnormal problem.

Small make up: air compressor for a long period of time without, now start to appear a problem, to boot, star delta conversion is completed, normal load, soon showpressure starting and stop, this is the reason why the air compressor fault? Like torepair?

Chi and Technology Master: This is not the compressor to run, water can not bedischarged in time, the minimum pressure valve and the pipeline valve cannot open normally rusty, you can try to clean the valve.

Small make up: how to remove the oil filter?

Chi and Technology Master: remove oil filter core, stop the machine to be fully cooled,with a belt board, carefully can be unloaded.

Small make up: how to remove the oil cooler?

Chi and Technology Master: it depends on your use of the air compressor is what type of, and the compressor is water cooling or air cooling? Removal of the oil cooler,with the complex procedure. The housing demolition, and then the connecting pipelineis unloaded, the cooler installed screw removal can be.

Small make up: exhaust pressure when the machi, , ne <, /SPAN>is greater than the set value of intake valve has been closed, but the current did not reach the current limit value, the vent valve how action?

Chi and master the technology: from the screw machine to explain, when the pressureis greater than the set value, the machine has been sent to uninstall instructions. Sono matter how the motor current, the bleeder valve will be gas unloading.

Small make up: please explain in detail the cold coal is more, less, influence on therefrigerating capacity.

Chi and Technology Master: refrigerant quantity is not enough, so that the machineevaporation pressure is not up to the required pressure, the machine runninguninterrupted, frost, the compressor surface pressure dew point to the desired temperature. The refrigerant quantity exceeds the compressor load.

Small make up: what is the role of the fuel cutoff solenoid? The host has an internaltemporary storage tank, two intake and exhaust valve in the host? How to repair when the intake and exhaust valve bad,?

Chi and Technology Master: shutoff valve is to prevent the machine downtime, cut off the fuel supply. No storage capacity of screw machinery of the host, the intake / exhaust can be assumed at both ends of the rotor, while the intake / exhaust valves are computer peripherals. The intake valve can be adjusted, the exhaust valve is acheck valve, if the function cannot be performed must be replaced.

Small make up: a compressor user has a compressor, need through the remote control to switch machine and obtain the alarm signal, the following operation is can realize I need: 1 through the external INTELLISYS CONTROLLER 3 on the 4 point and 5 point for No. 6, START and 2 INTELLISYS CONTROLLER STOP machine 32 with 33,33 and 34 switch quantity, take one gets the alarm signal 3 at the same time the machine is set to REMOTE if S/S. is not set to REMOTER whether S/S can alsoachieve the purpose.

Chi and Technology Master: your view is correct, done by remote control contactcontroller dedicated. While
