Abstract
The invention discloses a device for pressurizing and pressure maintaining anti-leak detection after corn harvester brake pump assembly. The device comprises a base. A fuel tank bracket is fixedly arranged at one end on the base, and a pump fixing fixture is arranged at the other end. A hydraulic fuel recycling tank is arranged below the pump fixing fixture. A primary return fuel filter and a secondary return fuel filter are arranged at the bottom of the hydraulic fuel recycling tank. A multi-way valve group is arranged below the fuel tank bracket, and the multi-way valve group is connected with a main pump operating handle and a branch pump operating handle. A pressure gauge is mounted on a side of the fuel tank bracket. A hydraulic cylinder is arranged at the inner bottom of the fuel tank bracket. A telescopic rod at the front end of the hydraulic cylinder is provided with a bolt. A hydraulic fuel tank is fixedly mounted on the fuel tank bracket. The hydraulic fuel tank is provided with a fine return fuel filter and a hydraulic fuel tank cover. A power switch is mounted on one side of the base. The device is provided with the hydraulic cylinder, so that pressurizing detection of a main pump can be realized. Fuel leaked from a brake pump is filtered and recovered by the hydraulic fuel recycling tank so as to be recycled. The operating handles are connected with the multi-way valve group, which makes detection simple and quick.
