Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A lubricating and cleaning system for large mechanical equipment comprises an oil supply mechanism 1, a cleaning mechanism 2 and an oil way distributor 3.

The oil supply mechanism 1 is connected with an inlet of an oil way distributor 3 through a main pipeline 4, and an outlet of the oil way distributor 3 is correspondingly connected with parts to be lubricated 6 one by one through a plurality of branch pipelines 5 (four branch pipelines 5 are shown in the attached drawing, and can be increased or reduced according to needs in actual use); the outlet of the cleaning mechanism 2 is communicated with the main pipeline 4; a load cell 7 and a control valve 8 are also provided on each branch line 5, and each control valve 8 is connected to the inlet of the washing means 2 via a washing branch 9.

When the pressure of the load cell 7 is higher than a specified value, the control valve 8 controls the cleaning branch 9 to be opened, and controls the connecting pipeline of the component 6 to be lubricated and the control valve 8 to be closed; when the pressure of the load cell 7 is not higher than a specified value (i.e., equal to or less than a specified value), the control valve 8 controls the purge branch 9 to be closed, and controls the connection line of the component to be lubricated 6 and the control valve 8 to be opened.

Fig. 1 shows a schematic diagram of the present invention, in which the direction indicated by an arrow is the flowing direction of fluid (cleaning liquid or grease) in a pipeline, a cleaning mechanism 2 is connected to a main pipeline 4 through a cleaning pipeline 10, a branch pipeline 5 is divided into a front branch 501 and a rear lubrication pipeline 502 by an electromagnetic valve, a load cell 7 is located on the front branch 501, and the rear lubrication pipeline 502 is connected to a component 6 to be lubricated.

When a line behind the load cell 7, i.e., the side closer to the end of the fluid flow in the direction of the fluid flow, becomes clogged, grease in the line accumulates, causing the pressure of the load cell 7 to rise. Therefore, in order to detect the condition of the entire branch pipe 5, the load cell 7 is preferably disposed at the outlet of the oil distributor 3, i.e., at the beginning of the branch pipe 5, and the control valve 8 is disposed at the end of the branch pipe 5, and it is determined that the cleaning operation and the lubrication operation are selected after the detection of the entire branch pipe 5 is completed. In addition, the main pipeline 4 is generally short in length and large in diameter, and the main pipeline 4 is generally arranged at a low position, so that the main pipeline 4 is less in blockage phenomenon and convenient to maintain, and therefore the maintenance of the main pipeline 4 is not considered.

According to the specific working principle, when one or more branch pipelines 5 are blocked, the corresponding load cells 7 display high pressure, the switches of all the control valves 8 are adjusted to the cleaning branch 9 at the moment, so that the cleaning branch 9 is switched on, the rear-section lubricating pipeline 502 is switched off, and the cleaning liquid after the cleaning mechanism 2 cleans the front-section branch 501 returns to the cleaning mechanism 2, so that the cleaning liquid can be repeatedly used. When each branch pipeline 5 is unblocked, the corresponding load cell 7 displays normal pressure, at the moment, the switches of all the control valves 8 are adjusted to the rear section lubrication pipeline 502, so that the cleaning branch pipeline 9 is closed, the rear section lubrication pipeline 502 is communicated, and the lubrication mechanism conveys lubricating grease to the part to be lubricated 6.

The washing machine 2 generally comprises a washing liquid storage tank 201 and a delivery pump 202 connected to an outlet of the washing liquid storage tank 201, an outlet of the delivery pump 202 is connected to the main line 4, and an inlet of the washing liquid storage tank 201 is connected to the washing branch 9. The cleaning liquid storage tank 201 stores cleaning liquid, the cleaning liquid can clean grease, the grease can be rapidly decomposed, the cleaning liquid can be purchased in the market, and the delivery pump 202 can be a common liquid pump. The cleaning mechanism 2 can be placed in a movable box body, and when the cleaning mechanism is needed to be used, the cleaning mechanism is moved to the side of equipment for use. Preferably, a filter screen is further disposed at an outlet of the cleaning solution storage tank 201, so that the recycling rate of the cleaning solution can be improved, and the cleaning solution with impurities can be prevented from blocking a pipeline.

The fueling mechanism 1 generally includes a tank 101 and a pump 102 connected to the tank 101, and an outlet of the pump 102 is connected to the main line 4.

The two-way outlet of the control valve 8 can be controlled manually. In order to improve the degree of automation and further reduce the labor, it is preferable that the load cell 7 is a pressure sensor, and the control valve 8 is a solenoid valve, both of which are electrically connected to the controller. As shown in fig. 2, when the pressure of the load cell 7 is higher than a specified value, the controller sends a signal to the control valve 8 to open the purge branch 9 and close the rear section lubrication line 502; when the load cell 7 pressure is not above the specified value, the controller sends a signal to the control valve 8, which closes the purge branch 9 and opens the rear section lubrication line 502. In addition, the controller can also set that after the part to be lubricated 6 stops working for a specified time, the cleaning branch 9 is opened, and meanwhile, the rear section lubrication pipeline 502 is closed, so that after the equipment stops working for a period of time, the pipeline 10 can be directly cleaned without opening the lubrication mechanism to detect whether the pipeline is blocked. Thereby achieving the effect of cleaning the pipeline 10 regularly and quantitatively.

Preferably, a first check valve 11 is disposed on a connection pipeline between the cleaning mechanism 2 and the main pipeline 4 for further controlling the on/off of the cleaning pipeline 10.

Preferably, the main pipeline 4 is provided with a second one-way valve 12, and the second one-way valve 12 is located in front of the connection between the cleaning mechanism 2 and the main pipeline 4 for preventing the cleaning liquid from entering the oil tank 101.
