Fuel filter and mechanical equipment

Abstract

The invention relates to the technical field of fuel filtering and cleaning of mechanical equipment, in particular to a fuel filter and mechanical equipment. The fuel filter comprises a drainage mechanism and a water storage body, wherein a drain hole is formed in the bottom of the water storage body, and a pressure relief hole is formed in the water storage body at a preset height away from the drain hole; the drainage mechanism comprises a drainage valve and a hollow elastic body which are connected, the interior of the hollow elastic body communicates with the pressure relief hole, and a first drainage through hole is formed in the bottom of the hollow elastic body; and the drainage valve is arranged at the drainage hole, and the hollow elastic body can expand or contract to drive the drainage valve to open or close the drainage hole. The mechanical equipment comprises the fuel filter. According to the fuel filter and the mechanical equipment, drainage can be automatically started or stopped in time, the manual maintenance workload is reduced, fuel and water are prevented from being mixed for use due to the fact that fuel and water are not separated in time, the quality of output fuel can be continuously and effectively guaranteed, the working performance of the mechanical equipment is protected, and the service life of the mechanical equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of fuel filter cleaning of mechanical equipment, in particular to a fuel filter and mechanical equipment. Background technique [0002] At present, the oil-water separator used in mechanical equipment needs to manually open the drain valve during daily maintenance, and then manually close the drain valve after maintenance. The degree of automation is low, so it takes a long time for maintenance. [0003] In addition, due to the negligence of the user, the water in the oil-water separator cannot be discharged in time, resulting in excessive water content in the fuel, which will cause the mechanical equipment using fuel to stall, the power will drop, and even serious problems such as damage to key components will occur. Contents of the invention [0004] The first purpose of the present application is to provide a fuel filter to solve the technical problems existing in the prior art that the oil-water separa...
