Abstract
The invention provides a rubber hose for a turbocharging air pump and a manufacturing method for the rubber hose. The rubber hose comprises an inner rubber layer, an outer rubber layer and a fiber yarn reinforcement layer. After the inner rubber layer of the rubber hose is extruded by an extruder, the inner rubber layer is directly wound with fiber yarns, the traditional spray device and process are eliminated, and human health is facilitated. The inner rubber layer is directly wound with yarns and outer rubber is extruded, so that the inner rubber layer, the fiber yarn reinforcement layer and the outer rubber layer are adhered well, the adhesion effect is directly achieved; therefore, the production process is simplified and the cost is saved; moreover, a filler can be mixed in advance under the mechanical action of a rotor, so temperature rise cannot be caused; and a peroxide vulcanizer is added finally and complementary milling is carried out by an open mill, so rubber materials can be fully mixed uniformly, the quality of semi-finished rubber materials is ensured, extrusion is facilitated and the functional performance of the product is ensured.
Description
Technical field
The present invention relates to the auto parts machinery field, more specifically to a kind of rubber pipe and production method thereof that is used for the turbosupercharging air pump.
Background technique
Because the continuous exploitation of global petroleum resources reaches the long-term threat that the global petroleum supplly chain causes, and causes the global oil price to rise steadily.In order to reduce automobile fuel consumption, the share that dominates the market increases the fuel-economy performance, and domestic main engine factory use the turbo-charging diesel motor that improves, thereby reach energy saving, increase the effect of efficient.
Motor is the heart of automobile, and the automobile power size is leaned on engine output, and the big fuel consumption of engine power is big; For Continual Improvement, domestic main engine factory change developing direction one after another, use for reference external successful experience; Motor is pursued high rise rate, and turbosupercharged engine becomes R&D direction.Turbo charge system comprises turbosupercharger, middle cold air, air inlet bypass valve, exhaust by-pass valve and supporting intake and exhaust pipeline.Turbosupercharger is a kind ofly to utilize the dump energy in the engine exhaust to come the air pump of work.The exhaust gas driven turbine wheel assembly; It is connected with compressor impeller, and the flexible pipe of turbosupercharger mainly is to be connected between turbosupercharger and intercooler and intercooler and motor; Conveying is cooled off by turbocharger supercharged gas to intercooler, is transported to motor by intercooler.
The flexible pipe of turbosupercharger is transported to turbine to the fuel oil waste gas vapour that is mixed with of the High Temperature High Pressure that has motor to discharge, and is transported to the intercooler cooling by flexible pipe after the supercharging, has flexible pipe to be transported to motor again, makes the waste gas secondary combustion of these discharges.Improve combustion efficiency of fuel oil like this, reduced toxic emission.Therefore use this technology to have environmental protection, effect of saving energy.Because the operating ambient temperature of motor can reach more than 200 degree, therefore requires the rubber hose material to have resistance to high temperature, can bear unexpected pressurized energy, and have oil resistance.And common rubber material does not possess such performance, needs to use special rubber material.The flexible pipe of turbosupercharger is all very important aspect material type selecting, prescription design, technological design, verification experimental verification, and at present domestic still do not possess these comprehensive exploitations and checking ability, so this hose technology is project leading in the world at present.
The blended fuel oil gas (possibly be gasoline, diesel oil, gas) that ability 200 degree high temperature and motor are discharged will be considered in the material type selecting aspect of the flexible pipe of turbosupercharger; In when design prescription, consider that aspects such as firmness change rate behind the high temperature resistant deep fat, volume change, powerful variance ratio, elongation change consider; To consider resistance to high temperature aspect the framework layer selection, select powerful height, the framework material that thermal shrinkage is little; On testing installation, select the impulse testing machine of the working state on the simulated automotive.
The maximum test that " high temperature " faces when being the turbosupercharger running.During turbo driving, at first contact is the high-temp waste gas (first thermal source) of being discharged by engine, the compressor impeller run-in synchronism that it promotes turbine wheel and has driven opposite side.The rotating speed of whole blade wheel shaft is 120000-160000rpm easily.So the heat that the turbine shaft high speed rotating is produced very surprising (second thermal source) is added the temperature (the 3rd thermal source) that air is improved after the gas compressor blade wheel compression, this three becomes the most severe high temperature burden of turbosupercharger.Turbosupercharger becomes a system that works alone that integrates the high temperature original paper.So " heat radiation " is extremely important for turbosupercharger.There is special Oil passage (heat radiation and lubricated) turbine body inside, has much to be designed with Oil passage and water channel more simultaneously, through oil cooling and the dual heat radiation of water-cooled, reduces the pressurized machine temperature.Motor is provided with middle cold air, reduces temperature, the raising density that is compressed air with this, prevents the engine producing pinking.The area of intercooler and thickness are big more, and its heat dissipation potential is strong more.Because area and thickness are big; Little flat tube quantity, length and radiator shutter etc. in it increase all thereupon; The outer atmosphere of high temperature compressed air in the intercooler and intercooler just has more area of contact and time of contact, and the area and the time of heat exchange (heat radiation) are more abundant, and cooling-down effect is better.Though big capacity intercooler has better cooling performance; But it has extended heat dissipation path with increased the air inlet content; Can bring the relative pressure loss; TurboLag becomes greatly in addition easily, and the flow of existing turbosupercharging sebific duct is (a fluorine silica gel): batching → banbury banburying → mill cooling sheet → applying → reel → exhaust down → roll up silica gel → exhaust again → cover die again to paste product figure number/date typing → sulfuration → cutting → post vulcanization → check → product cleaning → packing; In the cooling tube flow be: batching → banbury banburying → mill cooling sheet → extruder is down extruded inner glue layer → knitting → extruder and is extruded outer glue-line → cool off → cut → wear mould sulfuration → cleaning → cutting → post vulcanization → test package to put in storage.Intercooler pipe expressing technique is extruded line by one and is accomplished simultaneously; This flow is comparatively advanced; Adopt full machine interlock form; Laser diameter measuring instrument control internal diameter and external diameter; There is fluctuation caliper signal can feed back to the master control cabinet automatically if size is little; Extruder speed will be carried out suitable fine setting, be convenient to control inside and outside footpath size.The line products dimensionally stable is extruded in interlock completely, and up-to-standard rate is high, and manufacturing efficiency is high, thereby has reduced cost of production; Whole line is extruded the Adhesion force that helps between knitted layer and the outer glue-line; Because the service condition of turbosupercharger is harsh; Unexpected supercharging is in various degree arranged in the vehicle traveling process and heat phenomenon suddenly; What the connection between motor, middle cold air, the turbosupercharger was leaned on is rubber pipe, and rubber pipe bearing capacity, adhesion, heat-resisting quantity are particularly important.Outside the Pass wherein adhesion had with prescription design and yarn type selecting, design of the extruder shape of the mouth as one speaks and sliver interlock are produced had confidential relation, and whole line production helps the stability of product adhesion.
Summary of the invention
