The large air separation unit intrinsically safe system grounding

1 pay attention to the direction of the arrow on the valve and the process requirements of the media flow direction, in order to avoid installation errors. 2 The pipeline connected with the valve should be thoroughly cleared of dirt, dust and other foreign mechanical impurities before installation. Prevent damage of the sealing surface of the valve. 3 The cold valve on the cold box should be installed at the same time as the corresponding brack...

When the exhaust temperature of the piston compressor is higher than the design value, the most direct impact is that the lubricating oil is carbonized, which leads to the compressor parts burned out because of not getting good lubrication. If the temperature of the compressor is too high during actual operation, the cause should be analyzed in time and corresponding preventive measures should be taken. The following methods can be used for reference in practice. 1. Reducing the inlet air temperature can directly reduce the exhaust temperature. Check the intercooler to ensure the cooling effect of the intercooler. 2. The installation of the valve and the selection of the spring should be standardized to ensure the normal operation of the valve and minimize the loss of inlet and outlet pressure. 3. Strengthen the cooling of cylinder to ensure the normal compression process index. 4. Internal leakage is the main reason for the increase of exhaust temperature. 5.For multist
