AI Technical Summary

Technical Problem

In the existing technology, plate heat exchangers are prone to blockage due to impurities in the lubricating oil and scale in the cooling water during long-term use, which affects the heat exchange effect and cooling effect of the lubricating oil. At the same time, the cooling water circulation may experience pressure buildup, resulting in poor equipment operation.

Method used

A filtration mechanism, including a coarse filter and a fine filter, is installed before the plate heat exchanger to pre-filter impurities and scale in the lubricating oil and cooling water. The cooling water is then temporarily stored in a water tank for natural cooling through a circulation mechanism to avoid direct circulation. Combined with the pump, the cooling water is reused to ensure the cooling effect and smooth circulation of the lubricating oil.

Benefits of technology

It effectively prevents plate heat exchanger blockage, improves the heat exchange and cooling effect of lubricating oil, reduces cooling water waste, and ensures stable equipment operation.

Abstract

The utility model discloses a device for reducing the oil temperature of an oil station of an air blower, which belongs to the field of air blowers and comprises a water storage tank, a plate heat exchanger is fixedly connected to the top surface of the water storage tank, and a water return pipe is connected between a cold medium outlet of the plate heat exchanger and the water storage tank. Lubricating oil and cooling water are pumped into the plate heat exchanger through the first connecting pipe and the second connecting pipe through the oil inlet pipe and the water inlet pipe respectively, the lubricating oil and the cooling water can enter the filter box in advance respectively, and impurities in the lubricating oil and scale in the cooling water can be subjected to double filtration treatment through the coarse filter screen and the fine filter screen installed in the filter box. Lubricating oil and cooling water enter the plate type heat exchanger through the hot medium inlet and the cold medium inlet in the plate type heat exchanger respectively, and cooling treatment on the lubricating oil of the air blower oil station can be achieved on the plate type heat exchanger through the heat exchange principle.
