Which is the relay of Guangqi Honda Binzhi oil pump?

It is located in the fuse box in the front cabin. After opening, you only need to see the relevant marks on it. The intermittent operation of the oil pump indicates that the relay is normal. Check whether the power supply is correct and the line is short-circuited or open-circuited.

Quick-acting oil pressure relay is a new type of transformer oil tank pressure relay protection device. It is operated by the increase of dynamic pressure caused by oil tank accident. The faster the oil pressure rises, the faster it moves; Because the oil pressure wave propagates quickly in transformer oil, the quick-acting oil pressure relay is sensitive and accurate, and sends out a signal to cut off the power supply quickly. If a quick-acting oil pressure relay is installed on the transformer, once an internal short-circuit fault occurs, the oil tank can be prevented from exploding.

When the transformer is in normal operation, because the installation position of the quick-acting oil pressure relay is lower than the oil level line of the transformer, the oil chamber of the relay is connected with the oil tank of the transformer, and the isolation bellows in the oil chamber is subjected to small static oil pressure, which is compensated by the spring in the first air chamber to achieve balance, and the quick-acting oil pressure relay does not act. When the transformer fails, the pressure in the oil chamber will suddenly rise. When the pressure reaches the action value, the isolation bellows is deformed by the pressure, and the pressure in the I air chamber rises, so that the bellows is displaced, the microswitch acts, sends a signal, cuts off the power supply, and makes the transformer not run.
