Description

Hydraulic pipeline current collecting device

Technical Field

The utility model relates to the field of hydraulic system pipeline flow collection, in particular to a hydraulic pipeline flow collection device which is mainly used for pipeline design of a large-scale hydraulic pump station.

Background

The large-scale hydraulic pump station is usually provided with a plurality of paths of hydraulic oil output by the high-pressure oil pump, and each path of hydraulic oil is concentrated into a main pressure oil pipe through a pipeline and then is output outwards. The structure can reliably concentrate hydraulic oil together, reduce the risk of oil leakage caused by welding deformation of the piping in the integration process, and improve the economic benefit.

At present, the conventional oil collection design of a large hydraulic system pump station device generally adopts a mode of directly welding a cold-drawn seamless steel tube and a plurality of stainless steel three-way welded tubes for oil collection. For example, as shown in fig. 2, a plurality of three-way welded pipes are arranged in a row, a bottom passage forms a main pressure oil pipe, the upper parts of the three-way welded pipes are respectively connected with the pressure oil of the pumps of the various channels, and a welded pipe joint in threaded connection is also arranged for ensuring that each pump outlet pipeline is detachable. After being arranged in the way, the welding connection is carried out.

The pipeline flow collecting method constructed by the method is simple, but has high requirements on the level of welders and fitters because of more welded junctions and more mounting reference surfaces, and oil leakage points are easy to generate if the welding junctions and the mounting reference surfaces are slightly careless. The high-pressure oil is adopted here, the oil leakage speed of the positions of the leakage points is high, and oil leakage accidents and losses are easy to cause during production and debugging.

Disclosure of Invention

The technical problems to be solved by the utility model are as follows: (a) The collecting pipeline of the hydraulic system pump station is complex and difficult to assemble; (b) The welding ports of the collecting pipeline are more, the welding is difficult, and the oil leakage risk of the welding ports is high; (c) The welding deformation is relatively large, and dislocation is easy to occur at the pipe joint, so that oil leakage is caused; (d) When an accident occurs, the hydraulic oil in each path cannot be isolated from each other, and the risk of on-line maintenance of the oil pump is high.

The present utility model provides a hydraulic pipe flow collecting device, which can overcome the above-mentioned shortcomings of the prior art.

In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:

the utility model relates to a hydraulic pipeline flow collecting device which comprises a high-pressure filter block arranged on the side part of an oil tank, wherein an outlet of the high-pressure filter block is connected with a corresponding inlet on an integrated block through a corresponding pressure oil pipe, the integrated block is positioned on the upper part of the oil tank, a high-pressure ball valve which is correspondingly matched with each pressure oil pipe is arranged on the integrated block, and a main pressure oil outlet is arranged on one side of the integrated block. The number of high pressure filter blocks, pressure oil lines and inlets on the manifold block for connection will depend on the actual requirements.

The design has the following remarkable beneficial effects- (a) that most pipeline welded junctions in pipelines are reduced, so that the welding deformation is controlled in a small range, the installation is hardly influenced, and the risk of oil leakage of the welded junctions is reduced; (b) making the pipeline more beautiful; (c) The characteristics of the flange connection pipe are utilized, so that whether the sealing element falls off or is not installed in place during installation is easily seen, and the risk of oil leakage during installation is greatly reduced; (d) The plate-type high-pressure ball valve can temporarily and reliably separate a certain oil way from the main pressure oil pipe so as to facilitate the next overhaul operation.
