No matter what brand of oil injection air compressor, its compression working principle is the same, and the functions of each valve are roughly the same. If we can thoroughly understand the design function and working principle of each valve, we will give some support and help to solve the common faults of the air compressor! The five major valves of the oil injection air compressor are: unloadin...

During the operation of the compressor, many supporting accessories need to be well matched to meet the gas demand of the terminal, and the pressure vessel (gas tank) is one of the indispensable accessories. It can stabilize the pressure of the pipe network system, remove some pollutants, reduce the frequent startup and shutdown of the compressor, extend the service life of the compressor, and red...

What is the function of the emergency stop switch beside the control panel of the screw air compressor ? As the name implies, the emergency stop switch is mainly used for Deal with some emergencies. When the air compressor is in a dangerous state or a sudden failure occurs in the production process, in order to avoid greater damage, it must be delivered in time For shutdown inspection, we can cut ...

The "trip" fault is usually caused by the external power supply, which is not the cause of the air compressor itself and does not need to be handled; The "trip" fault caused by the tripping of other overload protectors must be taken seriously. If forced operation occurs, the air compressor unit may be scrapped. There are many reasons for tripping, the most common is high temperature tripping, espe...

Screw air compressor is widely used, and regular maintenance is the premise to ensure its normal operation. The main engine is the core part of the air compressor, which has been operating at a high speed for a long time. Similar to most operating machines, it must undergo preventive overhaul after a certain period of time or service life. The overhaul period is usually 30000-40000h (4-5 years). 0...

During the use of the Refrigerated air dryer, if the suction temperature is too high, which is much higher than the design dew point temperature, what should be done? We will provide solutions based on cause analysis: Cause analysis 1: The expansion valve is out of control. When the cooling load (air handling capacity) increases, the refrigerant suction temperature increases, and the temperature o...

In order for the compressed air system to operate normally, the air must be dry. This means that before entering the air network, there must be no liquid moisture in the air and the relative humidity must be low. Different methods can be used to remove water from compressed air, which will help maintain high air quality. One of the mainstream equipment used to dry compressed air is the refrigerati...

Generally speaking, the exhaust pressure is divided into: low pressure air compressor, exhaust pressure ≤ 1.0MPa; Medium pressure air compressor, 1.0MPa<discharge pressure ≤ 10Mpa; High pressure air compressor, 10MPa<discharge pressure ≤ 100MPa. High pressure air compressor is a safe and reliable supply system for breathing air and high pressure air, which compresses the air under free state...

Reasons for insufficient pressure 1. The gas consumption is greater than the gas supply The discharge pressure of the compressor can not reach the rated pressure. One common reason is that the user's gas consumption suddenly increases. One compressor is not enough, and it is too wasteful to open another compressor. 2. The air filter is blocked Among the alarm faults of screw compressor, the most f...

Removal of insufficient pressure 1. Plugging The way to reduce gas consumption is to check the operation of the drive air compressor and its pipe network, focusing on whether there is leakage. Small leakage is not easy to find, and large leakage will naturally cause system pressure drop and gas consumption reduction. According to statistics, the average leakage of compressed air accounts for 30% o...

For any small and medium-sized enterprise, a set of air compression system is a costly investment, so maintaining its efficient operation is the primary task of all end users. In theory, the initial investment of equipment accounts for 15%, the maintenance and management costs during the use period account for 15%, and 70% of the costs come from energy consumption. Therefore, in order to reduce th...
