Hitachi compressor 503DH-83C2Y first load operation is running empty and after the completion of the purge. Compressor load operation according to the following requirements: 1, Hitachi compressor 503DH-83C2Y car gradually close the vent blowing cutting or cutting oil in the compressor 1/4 Rated pressure operation one hour; within 1/2 Rated Pressure operating under 4-8 hours. 2, the compressor running at minimum pressure, no abnormal phenomenon, thereafter, the pressure was gradually increased; 3, for large high-pressure compressor, under the nominal operating time of not less than 24 hours; 4, the operation of the process, Check the following items: 1. The lubricating oil pressure, temperature and fuel conditions. Hydraulic before being fed into the distribution piping system shall not be less than 1 kg / cm 2. Crankcase lubricating oil-wet or fuselage should be: a crosshead compressor should not exceed 60 ℃. No crosshead shall not exceed 70 ℃. 2. Hitachi compressor 503DH-83C2Y smooth operation, all moving parts sound should be normal. 3. Measuring the inlet and outlet water temperature and check the cooling water supply, cooling water allowed to flow and intermittent bubbles and blockage phenomenon. Drain the cooling water temperature must not exceed 40 ℃. 4. The flange portion, seal, intake and exhaust cutting, cylinder head and water jacket, etc., shall not leak, oil spills, leaks. 5. Intake and exhaust Laval's work should be normal, safe cutting sensitive. 6. The connection part without loosening. 7. Exhaust temperature and pressure levels measured values ??should be consistent with the provisions of the technical conditions. 8. Motor heating conditions and the current value should be specified. 5. After the operation, dismantling the following items: 1. Hitachi compressor 503DH-83C2Y demolition cutting gas levels, all levels of the cylinder front cover, check the cylinder mirror friction and, if friction marks should find out why. 2. Check the piston rod surface friction conditions, should not have the phenomenon of wear scar and pull the road. 3. Removing all levels of gas cutting, check the cutting plate and cutting the body fit the situation, cutting sheet if cracks to spare for it. 4. Check the cross slide, with the fuselage rail friction surface of the friction conditions. 5. Remove connecting rod watts, crosshead pin, check the friction surface of the friction conditions. 6. Hitachi compressor 503DH-83C2Y replacement lubricant inside the fuselage. After the first operation the compressor; the mechanical running-around, and lubricants, cleaning effect, a large number of fine metal powder into the oil, so the work of the machine after 24 hours after all the oil should be replaced. After 200 hours operation, the oil once again ones. Changed twice, according to regular maintenance required oil changes. In order to make extravagant together evenly throughout the initial operation must have adequate lubrication.
