Engineering machinery air storage tank automatic drainage device and automatic drainage control method

Abstract

The invention relates to an engineering machinery air storage tank automatic drainage device and an automatic drainage control method and aims to solve the problem that the drainage operation is inconvenient in a conventional engineering machinery air storage tank. According to the air storage tank automatic drainage device, a sensor acquires mechanical parameters and transmits the mechanical parameters to a controller; the controller receives a parameter signal, makes judgment that whether water needs to be drained or not and transmits a draining electric signal when the water needs to be drained; a drainage valve is arranged on the air storage tank to receive the draining electric signal which is sent by the controller and executes the drainage action. The sensor is used for checking to acquire the drainage parameter indicating the drainage action, the controller calculates and controls whether the water needs to be drained through drainage valve, automatic drainage is realized, the drainage timeliness and reliability can be well guaranteed, manual leakage and drainage is eliminated, dried gas in the air storage tank is fundamentally guaranteed, and the stability and reliability of a braking system are greatly improved.

Description

technical field [0001] The invention relates to engineering machinery, in particular to an automatic drainage device for an air storage tank of the engineering machinery and a control method for the automatic drainage. Background technique [0002] Construction machinery such as loaders are often equipped with an air storage tank (air tank) as an energy storage device to store a certain amount of potential energy, which is used for mechanical braking. The machine compresses air into the air storage tank during the working process, and the moisture in the air moves along with the air It is compressed and condenses in the air tank. In order to prevent excessive water vapor in the gas storage tank from corroding the steel pipe in the brake pipeline, in severe cases, it will cause air leakage from the steel pipe, affecting the braking performance of the whole machine and driving safety; construction machinery requires the user to regularly drain the gas storage tank . However,...
