High exhaust temperature of screw air compressor

Screw air compressor exhaust temperature is high, why more and more manufacturers choose water lubricated air compressor produced by Shanghai granklin group?

The screw air compressor has a special PLC master controller, which can display the operating status, operating temperature, pressure, current, voltage, etc.

Common Faults

high 1. exhaust temperature

high temperature of air compressor is a common fault, especially in summer, the operating temperature of air compressor increases with the influence of ambient temperature. Generally, the upper limit of exhaust temperature of domestic micro-oil twin-screw/single-screw air compressor is 105 ℃ to 110 ℃, the upper limit of exhaust temperature of imported micro-oil twin-screw air compressor is 120 ℃ to 130 ℃, and the upper limit of exhaust temperature of domestic and imported oil-free dry screw machine is 260 ℃. At present, the micro-oil twin-screw air compressor is commonly used in China, and the normal temperature is 80 ℃ to 92 ℃.

When the air compressor runs to 100 ℃/105 ℃, the air compressor will give an early warning of high temperature, and when the temperature reaches 105 ℃/110 ℃, the air compressor will stop due to failure and show that the exhaust temperature is high.

1. The radiator is blocked and the heat dissipation effect is poor, resulting in high temperature shutdown

2. Insufficient screw oil/coolant or deterioration causes high temperature shutdown

3. The oil filter is blocked and insufficient oil supply leads to high temperature shutdown

4. The temperature control valve fails and the action is poor. Insufficient oil supply leads to high temperature shutdown

5. The temperature sensor fault temperature display is incorrect. High temperature shutdown

6,PLC to receive the signal is not correct, resulting in high temperature shutdown

7, the ambient temperature is greater than 40 ℃

8. The door panel filter is blocked and the air intake is small

9. Fan failure, not working or reverse rotation.

10. The radiator design is unreasonable, etc.

why do factories now choose oil-free air compressors?

The reason is that the water-lubricated air compressor produced by Shanghai Granklin Group is a 100% oil-free air compressor due to the use of water as lubricant. The head temperature of the water-lubricated air compressor is lower and the gas production is better.

Oil-free air compressors are becoming more and more popular due to their reduced maintenance and energy costs, minimized environmental footprint, and the possibility of product contamination.

What is oil-free air?

The degree of air purity required varies with the risk tolerance of any industrial process. The International Standards Organization (ISO) created ISO 8573-1 to enable manufacturers to define tolerance levels for air purity in their compressed air systems. The standard outlines the contents of solid particles, water and oil based on classification.

The strictest of these levels, level 0, ensures that the total amount of oil in the compressed air is less than <0.01 mg / m3. The key is to choose the classification that best suits your institution.

Manufacturing advantages of oil-free air

eliminate the risk of contamination

rest assured-when compressed air encounters the final product, there is always a risk of contamination; the best way to solve this problem is to never introduce oil into your airflow in the first place. Category 0 air allows manufacturers to avoid contamination risks, such as the risk of post-filter breaking oil filters, which can reduce product quality, increase the risk of product recalls and cause unnecessary downtime. Contamination risks damage your brand reputation, your bottom line, and even your customers' health.

Protect your assets-Oil-lubricated compressors always contain trace amounts of oil in the air produced. Trace amounts of oil can build up on pneumatic equipment and other valuable assets that use compressed air, increasing maintenance and replacement costs.

reduce environmental impact

minimize oil usage-Oil-filled screw compressors require 55 gallons of oil to be replaced every 6 to 12 months. The oil must then be disposed of correctly in accordance with the appropriate regulatory agency guidelines. Oil-free compressors do not require oil during the compression process, so it is enough to change the oil every two to three years.

Eliminate condensate discharge-When running an oil-injected compressor, a large amount of oil-contaminated condensate must be properly disposed of to protect the environment. To ensure compliance, the administration frequently monitors and regulates the disposal of contaminated condensate. The condensate from the oil-free compressor can be easily discarded or even recycled for other uses within the plant.

So now many factories and hospitals will choose the water lubricated air compressor produced by Shanghai Granklin Group.
