Embodiment Construction
[0018] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.
[0019] Such as figure 1 As shown, a maintenance method for a hydraulic oil tank without draining oil of the present invention adopts a hydraulic oil tank with a vacuum pump. Oil hole cover 4 and fuel tank breather 3, the bottom plate of the fuel tank body 5 has an oil outlet pipe 6 and an oil discharge opening and closing valve 7 connected to the bottom end of the oil outlet pipe, and the fuel tank breather 3 has a The respirator standpipe 2 connected to the inner cavity of the fuel tank body 5 is provided with a pipe hole opening and closing valve 1 on the upper half of the respirator standpipe 2, and the function of the pipe hole opening and closing valve 1 is to isolate the fuel tank. The respirator communicates with the inner cavity of the fuel tank body. The lower half of the respirator standpipe 2 is connected to one end of ...

The invention relates to an overhaul method capable of avoiding oil drainage of a hydraulic oil tank. According to the overhaul method, the hydraulic oil tank with a vacuum pump is adopted, and comprises an oil tank body, a sealing oil inlet hole cover, an oil tank breather, an oil drainage opening-closing valve and a breather vertical tube, a tube hole opening-closing valve is arranged on the upper half part of the breather vertical tube, the lower half part of the breather vertical tube is connected with one end of an air delivery tube, the other end of the air delivery tube is connected with a vacuum pump with a manual pushing-pulling rod, a vacuum pump opening-closing valve is arranged at the connection end of the vacuum pump, and a pressure gauge is arranged on the air delivery tube; all the opening-closing valves on the hydraulic oil tank are closed; and the interior of the hydraulic oil tank is vacuumized. By maintaining the components associated with the hydraulic oil tank when the interior of the hydraulic oil tank is in a vacuum state, the overhaul method disclosed by the invention solves the problems of oil waste, high pollution possibility and time waste due to the need of vacuumizing the hydraulic oil tank during overhaul, and oil leakage and the like due to the emergency situations of oil tube burst and the like during a running process of equipment.
Description
technical field [0001] The invention belongs to the technical field of automobile maintenance, and in particular relates to a maintenance method for a hydraulic oil tank without draining oil. Background technique [0002] When large-scale production vehicles need to disassemble hydraulic pumps, fuel tank pipelines, rear wheel brakes, rear wheel radiators and other parts for maintenance, it is necessary to drain the oil in the hydraulic oil tank, and then add the oil to the in the fuel tank. In this way, it is easy to cause loss of oil during the discharge and refueling process; it is also easy to mix in external impurities and pollute the grease. When encountering unexpected equipment failures such as bursting of the pipeline connected to the hydraulic oil tank or oil leakage from the rear wheel brake, if the remaining grease in the oil tank is not put into the prepared container within 10-15 minutes, the entire hydraulic oil tank will be damaged. All the grease leaks, cau...
