Scope: This document specifies the structure, basic parameters, requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of the water-lubricated bearing cooling water purification and supply device (hereinafter referred to as the device). This document applies to the design, manufacture, and inspection of water purification and monitoring devices for the cooling medium of water-lubricated bearings (freshwater or seawater). Main technical content: - The water purification rate after a single non-recycling treatment should not be lower than the requirements specified in Table 3. - Table 1: Water purification rate after a single non-recycling treatment. Particle diameter (mm) Particle density Water purification rate (%) ≥0.1 ≥2.0 ≥90 5.3 The alarm device shall have a low-flow alarm signal output function. 5.4 The protection grade of the electrical control box, centrifugal pump, electric drain valve, and flow meter in the protective device shall not be lower than IP44 as specified in GB/T 4208. 6 Test methods 6.1 Visually inspect the appearance of the device. 6.2 Determine the water purification rate using the CS-600 separator test device after a single non-recycling treatment. The CS-600 test device is used to measure the solid-liquid separation efficiency of the cyclone separator. By comparing the turbidity values at the outlet and drainage ports of the separator, the solid-liquid separation efficiency is calculated. This purification rate is related to the diameter and density of the solid particles. Larger particles and higher-density solid particles are easier to separate. 6.3 Use a multimeter to test the alarm signal output function of the water supply device. 6.4 Test the protection grade of the device according to GB/T 4208. 7 Inspection rules 7.1 The inspection of the water supply device is divided into factory inspection and type inspection. 7.2 Type inspectio
