The oil level meter DYW-250 for the thrust bearing of the air preheater is composed of an aluminum alloy die-cast tube body, a buoy indicating device, a protective frame, a window, and an upper cover or pressure relief valve. The window adopts a special glass tube built-in structure. Generally, transformers with smaller capacities use this oil level gauge. The working principle is to use the connected tube principle to make the oil level in the conservator clear at a glance on the connected glass tube.
Working principle
The oil level meter DYW-250 for the thrust bearing of the air preheater is used on the oil storage cabinets of fully sealed large and medium-sized transformers. When the oil level inside the oil storage tank changes, the floating ball on the connecting rod of the oil level gauge swings up and down, driving the rotation mechanism of the oil level gauge to rotate. Through the rotation of the magnetic coupling and pointer shaft, the oil level in the oil storage tank is indicated on the dial through the pointer. The oil level gauge is equipped with an over limit oil level alarm mechanism, which can achieve remote oil level monitoring.
The oil level meter DYW-250 has a simple structure, convenient installation, and is easy to view real-time oil levels.
