Problems solved by technology
The existing hydraulic cylinder cleaning method is to clean and remove the old oil in the oil tank and disassemble each actuator to clean the oil at the same time. On the one hand, the workload is large and time-consuming, and on the other hand, the old oil cannot be completely and thoroughly cleaned.
Sometimes a simple hydraulic device temporarily assembled is used as a cleaning device, and the effect is very poor

Embodiment 1
[0043] This embodiment is the use method of the above-mentioned device embodiment. For ease of understanding, this embodiment clears the old oil in the oil pump 1. Refer to figure 2 , but the clearing method of the clearing device can clear a plurality of oil cylinders, and the plurality of oil cylinders are oil cylinder groups. The embodiment of the cleaning method of the cleaning device comprises the following steps in sequence:
[0044]Ⅰ Connect the oil outlet of the first throttle valve 4 in the hydraulic cylinder cleaning device to the rodless cavity 2 of the cylinder 1, and connect the oil outlet of the second throttle valve 5 to the rod cavity 3 of the cylinder 1. Turn on the first hydraulic pump 11, the piston of the oil cylinder 1 moves to the limit position toward the direction of the rod chamber 3, and records the action direction toward the rod chamber.
[0045] The purpose is to discharge the old oil in the rod cavity 3 of the oil cylinder 1 back into the oil re...
Embodiment 2
[0055] This method can clear multiple oil cylinders at the same time. In this embodiment, three oil cylinders are cleared. See Figure 5 .Others are the same as the method embodiment one.

The invention relates to a removing and discharging device and method for a hydraulic oil cylinder. The removing and discharging device comprises two throttling valves and a three-position and four-way reversing valve. The throttling valves are connected with an oil opening A and an oil opening B of the reversing valve. An oil opening P is sequentially connected with a first on-off valve, a first hydraulic pump, a sixth on-off valve and an oil tank. An oil opening T is sequentially connected with a second on-off valve, a third on-off valve and an old oil collecting box. A hydraulic control type discharging valve is connected between the oil opening T and a water pump. A seventh on-off valve is connected between the second on-off valve and the oil tank. A second hydraulic pump is connected between the oil tank and the old oil collecting box. According to the removing and discharging method, the two throttling valves are connected with two cavities of the oil cylinder, old oil in the rod cavity is discharged back to the oil tank and is discharged out, and the discharged old oil is collected into the old oil collecting box. A first oil pump is started to output the oil in the oil tank out. A valve element of the reversing valve is moved, the oil opening A is connected with the oil opening T, the oil opening B is connected with the oil opening P, and old oil in the rodless cavity is discharged into the old oil collecting box. According to the device and method for the hydraulic oil cylinder, the old oil in the oil cylinder can be rapidly and comprehensively removed.
Description
technical field [0001] The invention relates to a hydraulic oil cylinder cleaning device and a cleaning method thereof. Background technique [0002] In the industrial field, the hydraulic system is widely used as the intermediate control and execution link between the automatic control system and the actuator. The normal operation of the hydraulic system and the quality assurance of the oil are inseparable. Once the quality of the hydraulic oil in the system deteriorates and cannot reach How to quickly and thoroughly drain the old oil in the system and replace it with new oil is faced with the requirement of use. The existing hydraulic cylinder cleaning method is to clean and remove the old oil in the oil tank and disassemble each actuator to clean the oil at the same time. On the one hand, the workload is large and time-consuming, and on the other hand, the old oil cannot be completely and thoroughly cleaned. Sometimes a simple hydraulic device temporarily assembled is us...
