The exhaust air of the air compressor shows that the temperature is too high, and there are generally two factors: internal and external

On the one hand, it is caused by the air compressor itself, such as: dust, coolant, lubricating oil.

The second aspect is that the ambient temperature is too high, because the temperature itself is high in summer, even if the air compressor is operating normally, it will also face high temperature problems.

The specific solution is:

Clean dust and oil, replace coolant and lubricating oil; At the same time, active exhaust equipment is installed to maintain air circulation, including the addition of cold air equipment to cool the environment.

Using the large amount of cool air provided by Jiafeng evaporative air conditioner, it can be positive pressure ventilation and drive away hot air, and at the same time, the cool breeze blowing on the equipment can also speed up heat dissipation and cooling.

What is the cause of the high exhaust temperature of the screw air compressor and the alarm shutdown? Fault phenomenon: The exhaust temperature of the screw air compressor reaches 100 alarm, and it will stop after exceeding 105. There are the following reasons:

1. The amount of lubricating oil is insufficient, and the specifications of lubricating oil are incorrect, and the viscosity is different.

2. Cooling water.

The amount is insufficient, the cooling water pressure is low, and the cooling water temperature (water-cooled type).

3. The oil cut-off solenoid valve is not energized or the coil is damaged.

4. The room temperature is high (air-cooled type).

5. The oil filter is blocked.

6. The temperature control valve is faulty.

7. The oil cooler is blocked (air-cooled type).

First, the actual exhaust temperature is not too high.

The thermometer display is inaccurate.

The temperature sensor is faulty.

Controller failure.

The temperature switch is faulty.

Second, the actual exhaust temperature is too high.

The lubricating oil has been used for too long.

The Wang filter is clogged.

The oil separator core is clogged.

Failure of the thermostat valve.

The lubricant level is too low.

The ambient temperature is too high.

The fan motor is reversed.

The fan motor does not rotate.

The outside of the air cooler is always too dirty.

The oil circuit of the air cooler is seriously fouled.

The cooler exhaust passage is not smooth.

The cooling water pressure is too low.

The cooling water temperature is too high.

The cooling water outlet line is blocked.

The oil cooler water circuit is heavily fouled.

The minimum pressure valve is jammed.

The check valve is jammed.

The shut-off valve cannot be fully opened.

Failure of the temperature control spool seal.

Find the heat source: 1. The air compressor itself produces too much heat.

2. The normal heat generated cannot be taken away.

For the first problem, the cause should be found in the gas path, such as: damage to the suction and exhaust valves at all levels, dirt, air backflow caused by the failure of the seal under the valve, and vortex. This generates a lot of heat.

The air compressor has to go through the four strokes of suction, compression, work and exhaust to produce high temperature and low pressure gas, and in order to ensure the normal suction of the next cylinder or the user's gas, the high temperature gas must be forcibly cooled. In this way, part of the normal heat is dissipated into the environment and part is taken away by the cooling water (or cooling fan). Poor heat dissipation and poor circulation of the cooling system are the main causes of high exhaust temperatures.

Radiator blockage, insufficient cooling water, damaged water pump, damaged thermostat, too much limescale, poor fan performance, etc.

In summer, the operating temperature will definitely be higher, as long as the equipment does not have a high temperature alarm, but once the temperature is too high, it needs to be dealt with immediately to avoid the impact on the equipment.

Suggestions: 1. Improve the workshop environment and try to make the air circulation in the workshop as much as possible;

2. Air-cooled regular purge of the radiator;

3. The water temperature should be strictly controlled for water cooling, and the cooler should be cleaned regularly, and the water should be softened to avoid scaling of the cooler;

4. If the temperature cannot be lowered, an external fan can be used to blow the air to cool down.

1. Poor environmental ventilation and heat dissipation. There are three main conditions in which the surrounding environment of the screw air compressor affects heat dissipation:

First, it is too close to a wall-like obstacle;

The second is that there are other heat sources near the screw air compressor, and the third is that the front door and side door of the screw air compressor are open when working, and the electric fan cannot form a strong air flow.

Hope it helps you and I wish you a happy life! !Thank you very much for your support and encouragement, we will be more attentive in the future

1.Normal oil loss.

Cause of failure: The air compressor exceeds the set time cycle for too long in normal operation, resulting in high temperature of the machine.

Contact the manufacturer to maintain the machine, replace the three filters and oil.

2.Abnormal oil loss.

Cause of failure: There are obvious signs of oil leakage inside the machine.

Solution: Check the oil leakage point, replace the aging pipe, leak oil at the interface, and reassemble the screws.

3.The air compressor is affected by the harsh environment during operation, which causes the air compressor to overheat.

Dust removal of the air compressor door panel, dust removal of the air compressor radiator, and close the pure.

Pay attention to dust the air compressor radiator, do not destroy the aluminum sheet of the heat dissipation hole on the radiator.

4.The air compressor temperature sensor is faulty.

The high temperature alarm of the air compressor may also be caused by the failure of the temperature sensor, and the phenomenon is sometimes good and sometimes bad, and the high temperature shutdown occurs from time to time.

Check the temperature sensor car line, whether there is damage or disconnection, and continue to report the overtemperature after the wiring is normal, then replace the temperature sensor to solve the problem.

Sum up. Air compressor is a necessary equipment for most factories, it is recommended to arrange regular machine repair to carry out a simple maintenance of the air compressor, regular dust removal and observation of the operation of the machine itself, can not solve the problem can directly contact the manufacturer for door-to-door service.

In terms of real experience, there are several air compressors in a 100-square-meter dense pure closed room, which often alarms and stops in the summer, and the motor will burn down when it is serious, which takes energy and effort.

A circular exhaust fan is installed to exhaust air, but the air volume is not large and the effect is not obvious; After a friend's introduction, a large negative pressure fan (Jiafeng brand) was installed, which does have a lot of air volume and more heat discharge, and can cope with it in most climates.

But in the summer, because the outdoor air temperature is also very high, simple ventilation is no longer effective.

The evaporative air conditioner that I tried to install here is still Jiafeng, because the electricity and equipment costs are not high, so only 2 units are used here. It is installed outside the air compressor room, and the cool breeze blows on the air compressor body through the elbow.

Because the air blowing in is particularly large and far away, and the temperature is much lower than the natural wind, not only the air compressor has lowered the temperature, but also the high temperature of the entire air compressor room has been improved, which is indeed possible. You can go and check it out.

If the valve plate of the valve is broken and the valve spring fails, it will cause the seal to be not tight, in addition, the gas valve is not put in place during installation, the air valve is tilted, and the ejector rod piece on the valve cover is pressed against the air valve, which also causes the gas valve to leak.

If the suction valve leaks, it will reduce the amount of air intake, increase the temperature in the cylinder, and increase the exhaust temperature; If the exhaust valve leaks, it will reduce the amount of exhaust and intake, so that the compressed gas will flow backwards, so that the temperature in the cylinder will rise, and the exhaust temperature will rise. The piston ring and the guide ring are worn, the piston ring is broken, the sealing effect of the air compressor becomes worse, and the gas on the compressed side will leak into the suction side through the piston ring, resulting in the internal gas of the cylinder block, the cylinder block heats up, and the exhaust temperature rises.

2 Corrosion of the equipment.

When the air compressor is overhauled, it is found that there is always some rust at the bottom of the valve cavity of the air chamber, and when the air compressor is started, the rust is easy to enter the air valve, resulting in the tilt of the valve plate, the damage of the spring, and the air leakage due to poor sealing, which will inevitably lead to an increase in the exhaust temperature. Because the compressed medium air is a non-pure gas containing oil, water and other components, the cylinder is cast iron, and the intercooler is an ordinary steel plate, and the material is easy to rust under the erosion of water vapor. After the air compressor is shut down, the cooling water has a large difference with the cylinder temperature, which is easy to condense, and the condensate formed cannot be evaporated in time, which will cause the cylinder wall to corrode.

In addition, the cylinder gasket is not tight, and the cooling water system is not tight, causing water to enter the cylinder block, which also makes the cylinder block rust.

3. Equipment fouling and water accumulation.

How to solve the high exhaust temperature of the air compressorCheck whether the lubricating oil is clean and whether the oil level is normal, if necessary, the lubricating oil should be replenished or replaced, check whether the fan motor speed is normal and whether the exhaust port is blocked, check whether the oil cooler and the surface of the aftercooler are clean, clean the outer surface of the cooler if necessary, check whether the environment has any impact on the air inlet and exhaust of the unit, if so, the influence of external factors should be excluded to ensure the normal ventilation of the unit.

Check whether the temperature control valve is damaged, check whether the solenoid coil and solenoid valve diaphragm are damaged, repair or replace the belt if necessary, check whether the filter element of the oil-gas separator is blocked or the resistance is too large, if there is an uproar, replace the oil filter element.

NotesWhen the air compressor is running, the bearing is required by temperature, generally should not exceed 95 degrees, if it exceeds this value, then it means that the bearing of the air compressor is overheated, and the bearing of the air compressor is overheated, which will accelerate the deterioration of the lubricating oil, and in serious cases, the bearing will be damaged, which will bring huge economic losses to the user.
