After the screw air compressor is installed and debugged, the general factory runs almost 24 hours a day except for maintenance. At this time, if the air compressor is of poor quality or fails due to improper operation, it will make people feel upset, which will not only increase the use cost, but also affect the production process. In this article, Emerdy Xiaobian will introduce how to judge and eliminate the oil leakage failure of the screw air compressor.
Kerosene penetration method: the inspection process is to wipe the body and cylinder head with cotton yarn head soaked with kerosene first, then wipe the places where cracks may occur with dry cotton yarn head and kerosene, and immediately put white powder on the map of these places. at this time, where there are cracks, kerosene will penetrate into the white powder, and the location and length of the cracks will be clearly displayed.
There are two control methods: one is a switch, when the pressure of the gas tank reaches the high limit set value, close the air inlet, when the pressure drops to the low limit set value, re-open the air inlet. The other is that when the gas tank reaches a certain pressure, the rotating disc slightly closes the air inlet under the control of the proportional valve. When the pressure of the gas tank further increases, the air inlet is further reduced. When the pressure of the gas tank is slightly reduced, the air inlet will be increased to stabilize the pressure in a certain range. When the pressure does not reach the regulating pressure, the intake valve disc is fully opened and the intake port is fully opened.
As a kind of general mechanical equipment, screw air compressor needs maintenance just like cars to ensure normal operation in the production process. Then why is there a warranty? Today, the editor of Emerdy will explain it in detail for everyone.
During the use of the screw air compressor, some problems need to be paid attention. If the product is used, it will cause the screw air compressor to malfunction or seriously affect the service life of the screw air compressor.
