Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0022] Figure 2 for Figure 1 Section view along AA. DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1 An embodiment of the present invention provides a flushing system for flushing hydraulic or thin oil facilities, comprising a flushing pump station 1, an oil supply distribution main pipe connected to the oil pump outlet of the flushing pump station 1, and an oil return collecting main pipe connected to the oil tank 11 of the flushing pump station 1; the end of the oil supply distribution main pipe is closed and a plurality of oil supply branches 22 for connecting to the oil inlet of the facility to be flushed are provided on the oil supply distribution main pipe, the end of the oil return collecting main pipe is closed and a plurality of oil return branches 32 for connecting to the oil return port of the facility to be flushed are provided on the oil return collecting main pipe, and the ends of the oil supply branch pipe 22 and the ends of the oil return branch pipe 32 are both removably provided with plugging parts.

[0025] The above-mentioned facilities to be flushed may be hydraulic pipelines / thin oil pipelines, or hydraulic equipment / thin oil equipment.

[0026] The end of the oil supply distribution main pipe is also the end away from the flushing pump station 1. In one embodiment, it is blocked by a blind flange. The end of the oil return oil collecting main pipe is also the end away from the flushing pump station 1. In one embodiment, it is blocked by a blind flange. The end of the oil supply branch pipe 22 is also the end away from the oil supply distribution main pipe, and the end of the oil return branch pipe 32 is also the end away from the oil return oil collecting main pipe; the above-mentioned plugging parts are also preferably blind flanges. When it is necessary to use a certain oil supply branch pipe 22 or a certain oil return branch pipe 32, the corresponding plugging parts can be removed.

[0027] Preferably, if Figure 1The oil supply distribution main pipe is connected to the flushing pump station 1 through the oil supply main pipe hose 42, and / or the oil return oil collecting main pipe is connected to the flushing pump station 1 through the oil return main pipe hose 43. The connection between the oil supply branch pipe 22 and the oil inlet of the facility to be flushed is preferably connected through the branch pipe hose 41; the connection between the return oil branch pipe 32 and the oil return port of the facility to be flushed is also preferably connected through the branch pipe hose 41. By configuring the oil supply main pipe hose 42, the return oil main pipe hose 43 and the branch pipe hose 41, the flexibility of the equipment layout of the system can be effectively increased, the impact of the site space layout can be reduced, and at the same time, the cumbersome bending and welding tools when connecting steel pipes can be avoided, saving time and labor. The end of the oil supply branch pipe 22 and the end of the oil return branch pipe 32 can adopt a flange structure to facilitate connection with the branch pipe hose 41; the end flange of the oil supply branch pipe 22 and the end flange of the oil return branch pipe 32 are preferably of the same specifications, and the branch pipe hoses 41 can be interchangeable, which can reduce the configuration specifications of the branch pipe hoses 41 and reduce costs.

[0028] If the amount of flushing oil required for the facility to be flushed is large, multiple oil supply branch pipes 22 can be gathered to supply oil to the oil inlet of the facility to be flushed at the same time. Accordingly, the flushing system also includes at least one multi-way oil supply joint pipe 24, and the multi-way oil supply joint pipe 24 has an oil supply outlet and multiple oil collection inlets, each of which is connected to an oil supply branch pipe 22 with a removed plugging piece; Figure 1 In the illustrated embodiment, a two-way oil supply union and a three-way oil supply union are included, the two-way oil supply union is connected to two of the oil supply branches 22, and the three-way oil supply union is connected to three of the oil supply branches 22. Similarly, the flushing system may also include at least one multi-way oil return union 34, the multi-way oil return union 34 having an oil return inlet and a plurality of oil return distribution outlets, each of which is connected to an oil return branch 32 with a plugging member removed.

[0029] In one embodiment, if Figure 1 , the oil supply distribution main pipe includes at least one oil supply distributor 21, each of the oil supply distributors 21 is provided with a plurality of the oil supply branch pipes 22, and both ends of the distributor 21 are provided with expansion connection flanges. When there is only one oil supply distributor 21, one end of the oil supply distributor 21 is connected to the oil pump outlet and the other end is sealed by a blind flange; when the oil supply branch pipes 22 of one oil supply distributor 21 are not enough, multiple oil supply distributors 21 can be expanded accordingly, that is, the above-mentioned oil supply distribution main pipe includes multiple oil supply distributors 21, wherein the head end oil supply distributor 21 is connected to the oil pump outlet, the two adjacent oil supply distributors 21 are connected by an oil separator connecting pipe 23, and the end of the end oil supply distributor 21 is sealed by a blind flange. Similarly, Figure 1The oil return collecting main pipe includes at least one oil return collector 31, each of which is provided with a plurality of oil return branch pipes 32 and both ends of the oil collector 31 are provided with expansion connection flanges; when there are a plurality of oil return collectors 31, the head end oil return collector 31 is connected to the oil tank 11, and the two adjacent oil return collectors 31 are connected through the oil collector connecting pipe 33, and the end of the end oil return collector 31 is sealed by a blind flange. By designing the scalability of the oil supply distribution main pipe and the oil return collecting main pipe, the number of oil supply branch pipes 22 and oil return branch pipes 32 can be configured as needed, which can meet the flushing requirements of equipment with a large number of oil inlets and return ports, and can also meet the requirements of flushing multiple facilities to be flushed at the same time.

[0030] Based on the above structure, the flushing system can be assembled in a modular manner, which is flexible and can meet the flushing requirements of various facilities to be flushed and the flushing needs of multiple facilities to be flushed at the same time, which significantly broadens the applicability of the flushing system and can also significantly improve the efficiency of the flushing work.

[0031] In a preferred embodiment, Figure 1 Each of the oil supply branch pipes 22 is provided with a flow regulating valve 221, which can adjust the oil supply flow of the oil supply branch pipe 22. For example, according to the specific engineering situation, the diameter of the pipes to be flushed varies greatly, or the same pipe may have a local diameter change. For the over-thick pipe or local pipe section, the oil may not fill the inner wall and the flushing may not be in place. In this case, by adjusting the flow regulating valve 221 on the oil return main pipe to increase the back pressure of the pipe system, it can be ensured that the oil fills each pipe and each section, flushes to every corner, and ensures the flushing effect.

[0032] Among the options, Figure 1 Each of the oil return branch pipes 32 is provided with a liquid flow sight glass 321, which can monitor the flow conditions of each oil return branch pipe 32 in real time to ensure that each oil return branch pipe 32 is sufficiently oiled and flushed efficiently. At the same time, the blockage of the oil return branch pipe 32 can also be discovered in time.

[0033] Further optimization of the above flushing system, such as Figure 1 and Figure 2 , the return oil collecting main pipe is connected to the oil tank 11 through a coarse filter pipeline. It can be understood that the coarse filter pipeline can perform coarse filtering on the return oil, that is, the coarse filter pipeline is provided with a filtering device, which can filter out larger particle impurities in the return oil, and prevent larger particle impurities from being brought into the filter 13 of the flushing pump station 1, thereby reducing the filter element loss of the filter 13 in the flushing pump station 1, and preventing the filter element from being blown up due to the attachment of larger particle impurities to the filter element of the filter 13, and preventing large particle impurities from entering the oil tank 11 and being sucked into the oil pump 12, thereby better protecting the oil pump 12 and improving the safety and reliability of system operation. Optionally, a return oil main pipe regulating valve 35 is provided between the return oil collecting main pipe and the coarse filter pipeline.

[0034] In one embodiment, if Figure 1 and Figure 2 The coarse filter pipeline includes two coarse filter pipes 51 arranged in parallel, and the two coarse filter pipes 51 are each provided with a coarse filter unit 52 and a switch valve 53. The two coarse filter pipes 51 can be used as backup for each other. By opening the switch valve 53 of the backup coarse filter pipe 51 and then closing the switch valve 53 of the currently working coarse filter pipe 51, operations such as replacing the filter screen can be achieved without stopping the machine, and the flushing efficiency is high, and the system operation is more reliable. Further preferably, as Figure 1 and Figure 2 A switch valve 53 is respectively provided before and after the coarse filter unit 52, and the coarse filter pipeline 51 operates more safely. The coarse filter unit 52 can adopt a conventional filter 13 such as a filter screen.

[0035] In an optional embodiment, if Figure 2 , a drain pipe 55 is provided on the coarse filter pipe 51, and a drain valve 551 is provided on the drain pipe 55. After the coarse filter pipe 51 has been working for a period of time, the drain valve 551 on the drain pipe 55 of the coarse filter pipe 51 is opened, so that the accumulated residue and particulate impurities under the filter can be cleaned online in real time. It has a simple structure and is easy to operate. It can avoid excessive residue accumulation on the inlet side of the coarse filter unit 52 and damage the filter 13, and also improve the flushing efficiency. Obviously, the above-mentioned drain pipe 55 is connected to the inlet side of the coarse filter unit 52; the residue accumulation part of the drain pipe is designed to protrude downward and form an acute angle with the direction of the liquid flow, so as to facilitate the accumulation of residue and particulate impurities. Further, as Figure 1 and Figure 2 Pressure gauges 54 are provided at the front and rear sides of the coarse filter unit 52 respectively. The filter flux of the coarse filter unit 52 is monitored in real time according to the pressure gauges 54 to determine whether the amount of slag accumulated at the inlet side of the coarse filter unit 52 is excessive.

[0036] In an optional embodiment, if Figure 1 In the flushing pump station 1, a bypass pipe 14 is provided on the oil supply main pipe at the oil pump outlet and connected to the oil tank 11, and a flow regulating valve 141 is provided on the bypass pipe 14 to adjust the flushing oil pressure in the oil supply distribution main pipe to avoid damage to equipment or pipelines due to excessive pressure.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
