Description

Cloth rubber corrugated pipe and cloth rubber corrugated flat pipe

technical field

The utility model relates to a rubber corrugated pipe, in particular to a rubber corrugated pipe with cloth for the intake pipe of a diesel engine filter of a railway locomotive power generation car, a circulating water vapor pipe, and a rubber corrugated flat pipe with cloth for a cable casing of a power generation car of a railway locomotive. It belongs to the technical field of engineering components.

Background technique

Cloth rubber corrugated pipes are mainly used to transmit fluid media, such as railway locomotive diesel engine filter intake pipes and circulating water vapor pipes are all made of cloth rubber corrugated pipes; cloth rubber corrugated flat pipes are mainly used as vibration damping protection sleeves, For example, the cable casing of the railway locomotive generator car adopts the cloth rubber corrugated flat tube. Since the cloth rubber corrugated pipe and the cloth rubber corrugated flat pipe can be freely elongated and compressed, and can produce up, down, left, and right bending deformations, the performance requirements for bending resistance, wear resistance, and tear resistance are relatively high. The traditional cloth rubber bellows winds the steel wire skeleton outside the cloth layer and then covers the rubber layer. Due to the constraints of the production process, the steel wire skeleton of the cloth rubber bellows is located at the wave crest of the pipe, not only in the cloth rubber bellows In the bending state, the outer diameter is very easy to wear and leak, and its bending angle is also limited, thereby shortening the service life of the rubber bellows.

In view of the above problems, a cloth rubber corrugated pipe that is bonded together by the outer layer, the middle layer, the steel wire skeleton and the inner layer came into being. The special feature is that the steel wire skeleton is arranged at the trough of the pipe, and the outer layer and The inner layer is made of wear-resistant and flame-retardant rubber material, so the bending resistance and wear resistance of the cloth rubber bellows are significantly improved; but the middle layer of the cloth rubber bellows adopts one or more layers of cloth structure, which is suitable for applications As far as the air intake pipe, circulating water vapor pipe and cable casing on the diesel engine filter of railway locomotive and generator car are concerned, due to the harsh working environment, the requirements for air tightness, oil resistance and corrosion resistance are very strict. Or the middle layer of the multi-layer cloth structure cannot meet the above requirements, so it is difficult to completely solve the problem of short service life of the cloth-clad rubber bellows. Equally, in prior art, be applicable to the cable bushing of railway locomotive generator car and adopt the cloth rubber corrugated flat tube that is bonded as one by outer layer, middle layer and inner layer, also do not thoroughly solve the problem of short service life.
