Device for pressurizing and pressure maintaining anti-leak detection after corn harvester brake pump assembly

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.

Description

technical field [0001] The invention relates to the field of corn harvesters, in particular to a pressure-holding and pressure-holding anti-leakage detection device for a brake pump of a corn harvester after assembly. Background technique [0002] At present, the brake pump of the corn harvester is controlled by the driver with the brakes on the master cylinder. The master cylinder is instantly pressurized and then controls the action of the slave cylinders. The safety of the braking system is ensured by maintaining the pressure of the slave cylinders, which requires the pressurization performance of the master cylinder. Good, the pressure-holding performance of the sub-cylinder is stable. In fact, due to the large size and heavy weight of the corn harvester, the requirements for the braking system will be higher. It is caused by unstable pressure holding. At present, there is no special equipment for testing the pressurization performance of the assembled master cylinder an...

[0002] At present, the brake pump of the corn harvester is controlled by the driver with the brakes on the master cylinder. The master cylinder is instantly pressurized and then controls the action of the slave cylinders. The safety of the braking system is ensured by maintaining the pressure of the slave cylinders, which requires the pressurization performance of the master cylinder. Good, the pressure-holding performance of the sub-cylinder is stable. In fact, due to the large size and heavy weight of the corn harvester, the requirements for the braking system will be higher. Caused by unstable pressure holding, there is no special equipment for testing the pressurization performance of the assembled master cylinder and the pressure holding performance of the sub-pumps.
