In the process of using the air compressor, when the tubing is blocked, there is no oil at the oil supply point. Oil leakage or oil supply plunger damage at the oil injection point is likely to occur in front of the blocked pipe section. The serious consequence is that the air compressor overheating, high temperature failure, machine necrosis and so on.So what are some of the causes of tubing blockages?How can we prevent this from happening?

1. Before installation, clean the tubing one by one, wipe it with alkali washing, water washing and white cloth or blow clean with air with pressure;

2. When the oil pipe of the air compressor is not long enough and needs to be connected long, the live joint should be installed, or the method of welding and lengthening by casing should be adopted to avoid welding slag or molten metal blocking the pipe;

3. When bending the pipe, use the pipe simmering tool for cold bending or oxy-acetylene flame heating and simmering, attention should be paid to preventing the simmering flat or metal from overheating and deformation;

4. After the tubing and oiler are assembled, the strength test of the system should be carried out, and the test pressure is 1.5 times of the operating pressure. When leakage or rupture is found, it should be repaired or replaced.
