Special concrete pump hose pump hose concrete concrete pump hose price rubber delivery hose ends Precautions a concrete delivery truck ends rubber hose, pressure Technical Data please users look for: 125A ordinary pressure may not over 4MPa, bending radius not less than 1M, each conveying capacity of not less than 10,000 cubic meters of concrete in normal use. Two, 150A ordinary pressure should not exceed 3.5MPa, bending radius not less than 1M, each conveying capacity of not less than 10,000 cubic meters of concrete in normal use. Three, 125AB high pressure steel curtain pressure not exceeding 10MPa, bending radius not less than 1M, each conveying capacity of not less than 12,000 cubic meters of concrete in normal use. Four, 150AB high pressure steel curtain pressure must not exceed 9.5MPa, bending radius not less than 1M, each conveying capacity of not less than 12,000 cubic meters of concrete in normal use. Second, the operator should be used to do normative work, do not have the standard operation shall not posts, the connection end of the pipe to prevent the card does not stick and seal damage and not containing added ring, took over when not using the same model diameter nozzle pipes, hoses and modern ordinary hose ends only for export use, nor replace the connecting elbow and straight pipe use, unauthorized use at your own risk. Third, you must deal with when plugging normal use, such as the exit of stacked concrete plugging plugging, plugging mixed warehouse type, line type plugging slurry diarrhea, concrete batch exceeds Plugging tubing, tubing gray skin accumulation type plugging , concrete mortar isolation Plugging pipe, concrete segregation type plugging, plugging additives segregation type, S type conveyor tube plugging, plugging external mixing extreme heat pipe type, outside temperature and extreme cold type plugging, plugging air backlog type, Diameter variant plugging, plugging large aggregate traffic runaway plugging and so on. Paranormal not removed will cause heating hose deformation of the inner tube extrusion and paddling aggregate collision wall, resulting in the accumulation of parts of hose bulging, especially concrete aggregate particle size appears very large 3.5cm plugging phenomenon, barely output The longer the greater the harm, also causing the hose inner wall pierced increasingly infrequent collision, eventually played drums will appear at small to large peeling phenomenon, where there will also constitute the same consequences (tube flange bonding flange at shedding). But as long as all aspects of selecting the correct state is certainly the best position to achieve a smooth delivery of concrete to reduce unnecessary losses. My company can be customized four-wire, five wire, various special models, special standard rubber hose. This product is suitable for concrete pump machinery, machine-terminus cloth to use and has a high abrasion resistance, withstand voltage characteristics of the concrete pump hose can be manually swing the rubber hose to complete, with environmental protection, high pressure, high wear, durable and durable Features, general operating temperature -40 ℃ ~ + 85 ℃.
