Embodiment 1

[0045] The hydraulic pump station equipment of the present invention is used to flush hydraulic pipeline oil. The main equipment of the hydraulic pump station includes: a variable pump (main pump), a screw pump (auxiliary pump), an oil tank, an internal circulation filter, a plate heat exchanger, and a heater , outlet filter, oil return main pipe filter and automatic PLC control system. The hydraulic pump station of the equipment is composed of two major systems: a power system consisting of a variable pump, an outlet filter, an oil return manifold filter, and a plate heat exchanger; an internal circulation system composed of a screw pump and an internal circulation filter, etc., sharing a fuel tank and heater. Its various technical data vary according to the size of the device it serves. There are 2 or more main pumps; generally there are 2 auxiliary pumps. Due to the different sizes of service devices, it is impossible to achieve economical and applicable oil flushing equip...

Abstract

The invention discloses a method for flushing hydraulic pipe oil through hydraulic power unit equipment. The method is applicable to off-line acid pickling and stainless steel pipes. The pressure, flow velocity and flow of the hydraulic power unit equipment are matched with a device pipe to be flushed in the design process. The method is characterized by comprising the steps of preparation before hydraulic pipe oil flushing, main hydraulic pipe flushing, branch hydraulic pipe flushing and oil sample detection. The method for flushing the hydraulic pipe oil through the hydraulic power unit equipment has the advantages that the flow, pressure and flow velocity of the oil flushing equipment are matched with those of the device pipe to be flushed, the oil cleanliness which is originally designed in the NAS7 grade is improved to be higher than the NAS5 grade, the construction period is shortened, and the economical benefit is remarkable.

Description

technical field [0001] The invention relates to a hydraulic pipeline oil flushing method, in particular to a hydraulic pipeline oil flushing method using hydraulic pump station equipment. Background technique [0002] Hydraulic pipeline oil flushing is a crucial process in the installation process of hydraulic pipelines. Its quality directly affects the commissioning, reliability and service life of the entire hydraulic system. However, it is difficult to match the flow rate, flow rate and pressure between the flushing pump station used in the known hydraulic pipeline oil flushing and the pipeline of the device to be flushed, resulting in long flushing time, unstable quality, large amount of flushing oil, and high cost. [0003] Therefore, there are above-mentioned inconveniences and problems in the known flushing pump station in hydraulic pipeline oil flushing. Contents of the invention [0004] The purpose of the present invention is to propose a method for flushing hyd...
