an expansion tank

Abstract

The invention discloses an expansion water tank. A baffle is slidably arranged inside the box, and the partition is dynamically sealed with the side wall of the box; A pressure balance device for supporting the partition is arranged between the water chamber, the partition and the bottom plate of the box. When the water storage in the water chamber decreases, the gravity of the water body in the water chamber decreases, and the water supply pressure of the expansion tank to the radiator also decreases accordingly, and the force balance between the pressure balance device and the gravity of the water body in the water chamber is broken , the pressure balance device drives the partition to move upward until the supporting force provided by the pressure balance device is equal to the gravity of the water body in the water chamber again, and the state of force balance is reached again, maintaining the distance between the water level in the water chamber and the radiator The height difference is to ensure that the water supply pressure of the expansion tank to the radiator remains constant, thereby ensuring the normal operation of the radiator and its related components.

Description

technical field [0001] The invention relates to the technical field of mining vehicles, in particular to an expansion tank. Background technique [0002] Usually, the radiator part of the engine of the mining vehicle will be equipped with an expansion tank to meet the cooling demand of the radiator part during the working process. With the continuous improvement of production intensity, people have put forward higher requirements for the performance of the expansion tank. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a typical expansion tank and radiator in the prior art. [0004] In the current expansion tank part, the expansion tank 12 is usually arranged above the radiator 11 , and the assembled expansion tank 12 communicates with the radiator 11 . During the working process, when the water in the radiator 11 is consumed, the water stored in the expansion tank 12 will automatically flow under the influence of its own gravity and ...

Problems solved by technology

[0005] However, in the actual use of the existing expansion tank, since the water in the expansion tank 12 enters the radiator 11, the amount of water in the expansion tank 12 will decrease, the total gravity of the water body will decrease, and the water level will drop. The water pressure in the tank decreases, which affects the normal water supply of the expansion tank 12 to the radiator 11
