Inspection And Maintenance Methods for Gas Compressors After Cracks Appear

The inspection and maintenance methods for cracks include:

1. Permeation kerosene method: The inspection process involves first wiping the machine body and cylinder head with a cotton yarn soaked in kerosene, and then using dry cotton yarn to wipe areas where cracks may appear with kerosene. Immediately, white powder is applied to these areas. At this time, in areas with cracks, kerosene will penetrate into the white powder, and the location and length of the cracks will be clearly displayed

2. Water pressure method: Water pressure method is a method of increasing the pressure of cooling water to check the crack location. Water pressure inspection is carried out on a specialized equipment - a water pressure tester. In enterprises with poor equipment environmental conditions, some can even inspect simple equipment by modifying ordinary hand pressure water pumps. First, try to block the water pipe joints of the machine body or cylinder head, and only connect one of the water pipe joints with a rubber hose to the water pump outlet. A dedicated cover plate of equivalent size should be selected on the upper surface of the machine body to prevent the cooling water from overflowing. Then turn on the switch to press the water pump, and the chamber water enters the cooling water jacket. After the switch releases water, turn off the switch and continue to press the water pump until the pressure gauge reaches 3-4 atmospheres, then stop supplying water. At this point, the presence of cracks can be determined by checking whether there is any leakage or seepage in the body, inside and outside of the cylinder head.
