Therefore, the hydraulic operating oil piping system including the hydraulic system or the hydraulic operating system piping system which does not include the hydraulic system for the purpose of preventing the failure and preventing the operation failure and extending the service life by reducing the maintenance cost, And the flushing operation is performed on the sole.

In the flushing operation, a flushing operation method using a gaseous medium or a liquid medium and a work method such as a cleaning operation by a manual operation are applied according to the characteristics of each component and the purpose of use of each device. A circulation type cleaning method for circulating and flushing a flushing fluid in a piping system has been commonly used.

In the circulation type cleaning method, the circulating fluid for flushing continuously circulates the inside of the piping system, and the pollutants remaining in the circulation fluid are contained in the circulating fluid and discharged to the outside of the system. At this time, And the flow state of the circulating fluid has a great influence on the flushing effect.

Generally, the fluid flow state can be divided into laminar flow or turbulent flow, and the flow required in the flushing is a turbulent flow state, and the determination is determined by the Reynolds number and the condition is usually Reynolds number 3000 or more. In the case where a plurality of apparatuses are arranged on one pipe line, the branch pipes corresponding to the number of devices constituting the main pipe are branched, so that the pipe diameters of the respective branch pipes are relatively small, Flushing of the main pipeline reduces the flushing effect of the main pipeline and flushing the main pipeline causes the piping diameter of the branched branch piping to be too small on the main pipeline, So that the terminal portion of the main pipe can not satisfy such a demand The situation occurs.

A method of minimizing the length from the branch pipe branching at the final stage of the main piping to the end of the main piping to facilitate flushing or a method of directly connecting the piping connected to the equipment at the final stage to the terminal unit, And a method of using pressure flushing equipment.

These conventional methods for flushing may be some complementary measures, but recently, they have been pressurized to reduce the weight of the whole part related to the equipment. Such high-pressure equipment is highly precise, The hydraulic fluid used to operate the supply piping and hydraulic equipment requires high quality cleanliness, which leads to the failure of the operation and maintenance of the hydraulic equipment due to various reasons. Respectively.
