Description
Technical Field
The utility model relates to a hydraulic pressure oil pipe technical field, a turn over after specifically and inhale oil discharge rubber tube for dumper.
Background
The hydraulic mechanism of the backward dump truck needs to use an oil suction and discharge rubber pipe, and the backward dump truck is required to have good oil resistance, heat resistance, aging resistance, flexibility resistance and fatigue resistance, and has high bearing capacity and excellent pulse resistance. The existing rubber tube often has the phenomena of unstable pressure, even tube burst and the like in the permanent process. When an oil pump absorbs oil, the phenomenon that the inner rubber layer integrally falls off sometimes occurs, and the use requirement can not be well met.
SUMMERY OF THE UTILITY MODEL
In order to overcome the shortcoming that above-mentioned prior art exists, the utility model aims to provide a turn over after for tipper inhale oil discharge rubber tube, this rubber tube has good resistant oily, heat-resisting, ageing-resistant, resistant winding nature and fatigue resistance to the pressure-bearing capacity is high, and anti pulse performance is excellent.
In order to solve the problem, the utility model adopts the following technical scheme: the utility model provides a turn over after with inhaling oil discharge rubber tube, characterized by includes by inside toward 5 outer structural layers constitute, does in proper order: the inner rubber layer and the outer rubber layer are made of chlorinated polyethylene, the inner pressurizing layer and the outer pressurizing layer are formed by winding a cord which is externally wrapped by a layer of chlorinated polyethylene, the winding directions of the inner pressurizing layer and the outer pressurizing layer are opposite, clockwise winding and anticlockwise winding are respectively realized, and the spiral steel wire layer is formed by spirally winding a steel wire.
Further: the distance between the steel wires of the spiral steel wire layer is 0.6 cm.
The utility model has the advantages that:
1. the rubber has good oil resistance, heat resistance, aging resistance, flexibility resistance and fatigue resistance, and has high bearing pressure and excellent pulse resistance.
2. The inner rubber layer and the outer rubber layer are both made of chlorinated polyethylene, so that the rubber tube has good oil resistance, heat resistance, aging resistance, flexibility resistance and fatigue resistance.
3. The inner pressurizing layer and the outer pressurizing layer are formed by winding a layer of cord wrapped with chlorinated polyethylene, and the winding directions of the inner pressurizing layer and the outer pressurizing layer are opposite, so that the rubber tube is high in pressure bearing capacity and excellent in pulse resistance.
4. The spiral steel wire layer is formed by spirally winding steel wires, and the distance between the steel wires is 0.6cm, so that the rubber tube has high pressure bearing capacity and excellent pulse resistance.
5. The inner rubber layer and the outer rubber layer are extruded by an extruder, so that the inner surface and the outer surface of the rubber tube are smooth and attractive, and the cracking phenomenon in the using process is avoided.
6. The inner pressurizing layer and the outer pressurizing layer are formed by winding the cord with the outside wrapped by the chlorinated polyethylene layer, the material of the outside wrapping of the inner pressurizing layer and the outer pressurizing layer is the same as that of the inner rubber layer and the outer rubber layer, the adhesiveness of the inner pressurizing layer and the inner rubber layer, and the adhesiveness of the outer pressurizing layer and the outer rubber layer are stronger when vulcanization is carried out, and the phenomenon that the inner rubber layer integrally drops is effectively avoided.
Drawings
The invention is further described with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1 inner rubber layer, 2 inner pressurizing layer, 3 spiral steel wire layer, 4 outer pressurizing layer and 5 outer rubber layer.
Detailed Description
As shown in fig. 1, the oil suction and discharge hose for the tip-back dump truck comprises an inner layer and an outer layer of 5 structural layers, which are sequentially as follows: interior glue film 1, interior pressure intensifying layer 2, spiral steel wire layer 3, outer pressure intensifying layer 4 and outer glue film 5, interior glue film 1 and outer glue film 5 be the chlorinated polyethylene material, interior pressure intensifying layer 2 and outer pressure intensifying layer 4 be the outside curtain winding that has wrapped up one deck chlorinated polyethylene and form, and the winding direction of interior pressure intensifying layer 2 and outer pressure intensifying layer 4 is opposite, is clockwise winding and anticlockwise winding respectively, spiral steel wire layer 3 form for steel wire spiral winding, the interval of steel wire is 0.6 cm.
The present invention is not limited to the above embodiment.
Claims (2)
