Today, I will tell you about the cause of the failure of the air compressor.
First, the exhaust temperature of the main engine is high, exceeding 109 degrees, and the ambient temperature is high and the discharge of the convection equipment is unreasonable. An exhaust fan should be installed to lower the indoor temperature and remove the equipment box cover for ventilation.
Second, the host is overloaded with electricity, the friction of the host is large, the motor bearing is damaged, the voltage is too low, and the exhaust pressure is too high. Check the pressure gauge and adjust the pressure switch.
Third, the fuel consumption is too large, and the oil content in the air is large. If the oil level is too high, check the oil level and then discharge it to the correct position. There is no pressure difference before and after the oil and gas separator is damaged and separated, and the separation core should be replaced in time.
1. compressor not loaded
1. Causes of failure:
a. The pressure on the pipeline exceeds the rated load pressure, and the pressure regulator is disconnected.
B, solenoid valve failure.
C, oil and gas separator and unloading valve between the control pipeline leakage.
2. Methods of exclusion:
a, do not need to take measures, the pressure on the pipeline is lower than the pressure regulator loading (position) pressure, the compressor will automatically load.
B, remove the inspection, if necessary, replace.
C, check the pipeline and connection, if there is leakage, need to repair.

e. Check and clean if necessary
excessive 3. fuel consumption
1. Causes of failure:
a, oil level is too high

d. Clean the flow limiting hole
e, replace the recommended brand of oil
increased 4. noise
1. Causes of failure:
a. The bearing at the intake end is damaged
b, exhaust end bearing damage
c, motor bearing damage
2. Methods of exclusion:
remove and replace
5. displacement and pressure are lower than the specified value
1. Causes of failure:
a, air consumption exceeds the exhaust volume
b, air filter element blockage
c. Leakage of safety valve
d. Compressor failure
e. There is leakage on the control pipeline between the oil-gas separator and the unloading valve
2. Methods of exclusion:
a, check the connected equipment, clear the leakage point or reduce the gas consumption
b, remove the inspection, if necessary, clean or replace the filter element
c, remove and check, if it is still not sealed after repair, replace it
d, contact with the manufacturer, after consultation to check the compressor
e, check the management and connection, if there is a leak, need to repair
after the 6. is stopped, the air oil mist is sprayed from the air filter
1. Causes of failure;
leakage or damage of compressor check valve
2. Methods of exclusion:
remove and check, replace if necessary, and replace the air cleaner element at the same time
fuel injection in air filter after 7. shutdown
1. Causes of failure:
oil cut-off valve blocked
2. Methods of exclusion:
remove for inspection and cleaning, and replace the air cleaner element at the same time.
No discharge of condensate during 8. operation
1. Causes of failure:
a. Drain pipe is blocked
b, automatic drain valve failure
2. Methods of exclusion
a. Check and dredge
b. Remove and check
discharge safety valve immediately after 9. loading
1. Causes of failure:
failure of safety valve
2. Methods of exclusion:
remove and replace damaged parts
normal operation of 10. compressor, difficult to start after shutdown
1. Causes of failure:
a, the use of oil brand is wrong or mixed oil
b. Oily sticky and coking
c, shaft seal serious air leakage
d. Original position change of unloading valve flap
2. Methods of exclusion:
a, should be cleaned after a thorough oil change
b, should be cleaned after a thorough oil change
c. Remove and replace
d. Re-adjust the position
With the renewal and replacement of the times, the traditional oil-injected screw air compressor has received the impact of the market. More and more users are more inclined to use micro-oil and oil-free air compressors. On the one hand, the country is becoming more and more strict in environmental governance. On the other hand, it is in the long-term life of enterprises.
There are so many domestic air compressor manufacturers, and the number is large. Before purchasing, it is best to look at the factory scale, production capacity, and various certifications and user cases of the product, and evaluate whether the air compressor manufacturer can meet its own needs.
View detailsIn order not to affect the production progress of enterprises, most enterprises will be equipped with two screw air compressors, one open and one standby. The standby machine is mainly for emergency use. Only when the gas consumption is not enough or the common machine fails will it be used. Usually it is in a shutdown state, and the number of times it is used is not much. So what should be paid attention to when using the standby machine that is in a state of shutdown for a long time?
When we have prepared the preliminary preparations, the oil-free air compressor can be started according to the following procedures: 1. The unit is turned on, check whether the rotor and the stator have abnormal phenomena such as friction and collision, and confirm that the rotor is turned on flexibly; 2. Slowly lift the starter handwheel,
The semiconductor industry is undoubtedly an industry that needs to break through the technological blockade in the next 10 years. In the global semiconductor industry, the development of the domestic semiconductor industry is relatively late. In the process of gradually breaking through the technological blockade in various industries, semiconductor companies are also gradually expanding the scale of the industry. In the semiconductor industry, the "oil-free compressed air" of the "water-lubricated air compressor" It is an important role in development.
For enterprises to choose low energy consumption, environmental protection of the air compressor is a must, now so fierce competition, the need to control every aspect of enterprise production, in order to bring profits. Permanent magnet variable frequency air compressor has the characteristics of environmental protection and energy saving, which is well known, but the price of equipment with good performance and environmental protection must be expensive?

View detailsGood or bad depends on the occasion of use and the actual working conditions. In some cases, such as food, medicine, precision instruments and other industries, it is necessary to use a full oil-free air compressor. But the whole oil-free air compressor is much more expensive and the maintenance cost is higher. If it is used to blow
Users who use screw air compressors often complain about the accumulation of water in the head of the air compressor, and some even appear on the new screw air compressor that has just been used for a short time, causing the head of the screw machine of the air compressor to rust or even get stuck and damaged, and losing money and time.
As a kind of driving power energy, the application scenario of air compressor is more common and plays a very important role in all production and processing. However, in the operation of the air compressor, the actual effect of refrigeration and heat transfer is not very good, the working pressure is abnormal, and the displacement is not enough.
