The core functional positioning of the metal oil pump components designed by Atlas Copco for the ZR/ZL 55-90 series screw air compressors
This kit provides maintenance and servicing support for the metal oil pumps of the ZR/ZL 55-90 models. By replacing the key wear parts inside the oil pump, it restores the oil supply pressure and flow stability, ensuring that all moving parts of the compressor (such as screws, bearings, etc.) are adequately lubricated, and preventing insufficient lubrication or abnormal system pressure due to oil pump failures.
Typical components included
The contents of the kit are determined based on the design of the oil pump and usually cover:
The internal gear/rotor components of the oil pump (solving the problem of reduced oil supply efficiency due to wear);
Sealing components (such as oil seals, O-rings, gaskets, etc., to prevent oil leakage);
Supporting components such as bearings, shaft sleeves (reducing rotational friction and ensuring smooth operation);
Control elements such as check valves, pressure regulators (maintaining system pressure stability);
May include special installation tools or locating pins and other auxiliary accessories.
Material and design features
The metal components (such as gears, shaft sleeves) are made of high-strength alloy materials, processed and heat-treated precisely, with good wear resistance and fatigue resistance, suitable for long-term high-load operation;
Sealing components use oil-resistant, high-temperature-resistant elastic materials (such as fluororubber), matching the characteristics of the compressor lubricating oil, ensuring the sealing performance in high-temperature oil environments;
All components strictly follow the original factory design standards, with dimensions precisely matched to the oil pump housing, ensuring that the gear meshing clearance, pressure control accuracy, etc., after assembly meet the operating requirements.
Original equipment advantages
Performance matching: Designed specifically for the oil pump parameters of the ZR/ZL 55-90 models (such as displacement, pressure range), ensuring that the supply capacity after maintenance precisely matches the overall lubrication requirements of the machine, avoiding system failures caused by insufficient flow or excessive pressure;
Reliability guarantee: Original factory quality control ensures the durability of components, reducing the probability of secondary maintenance in the short term, and extending the service life of the oil pump;
System compatibility: Works in coordination with the lubrication system, temperature control system, etc. of the compressor, maintaining the stability of the oil circulation, indirectly ensuring the efficiency of cooling, filtration, and other related systems.
