IVG物料管混凝土泵车管正确使用和维护(ABR SHANNON 85)

Inspection 检验
Both prior to and during usage, we suggest that regular controls are carried out on the rubber tube and on the fittings by an adequately prepared staff person.
The controls to make on the rubber are necessary to verify any anomalies, such as:
- the condition of internal abrasion;
- the separation of the ferrule from the tube;
- the presence of bubbles, cuts, or abraded areas that may indicate a break in the reinforcement layers;
- the presence of old concrete on the inside.
On the fittings, the controls are to verify:
- any breaks, dents, holes or deformations of the components;
- presence of old concrete especially on the inside the gasket cavity that can preclude its use;
- that the fittings don’t show abrasion/erosion signs.
为发现任何异常,在橡胶上的 检查是必要的,如:
- 内部磨损的状况;
- 套筒是否从管子分离;
- 气泡,划伤或磨损的区域,可能表明在加强层有裂开;
- 先前的混凝土滞留在管子里。
- 任何破损,凹陷,孔或部件的变形;
- 先前混凝土滞留,尤其是在垫圈内腔,可妨碍其使用;
- 接头无磨损/侵蚀的痕迹。

Instruction 指导
Periodically it is necessary to reverse the two ends, creating a progressive rotation of the hose of 180° on its own axis.
The degree of erosion or abrasion of the assembled length is proportional to the speed and the quantity of the flow and to the type/ granulometry of the material conveyed. The bending of the assembled length influences the effects caused by the abrasion of the material: a reduced bending radius favours the abrasion of the tube, reducing consequently the duration of the product.

Cleaning 清洁
The assembly must be cleaned after every use with the correct equipment. We suggest carrying out the cleaning operation by sucking a sponge ball from one end to the other.
Compressed air must not be used for the cleaning.
An incorrect cleaning of the hose could generate occlusions of concrete with possible risks for employees.
For SAFETY REQUIREMENTS refers to UNI EN 12001 specification: “Conveying, spraying and placing machines for concrete and mortar - Safety requirements.”
相关安全规定请参考UNI EN 12001规范:“混凝土和砂浆的输送,喷涂和浇注设备-安全要求”。

Recommendation for correct storage 正确储存的建议
Rubber is subject, by nature, to change in physical properties. These changes, which normally occur over the course of time, according to the kind of rubber used, can be accelerated by one particular factor or by a combination of these. Reinforcement materials are also adversely affected by unsuitable conditions of storage. The following recommendations give some precautions to be taken to ensure the
minimum deterioration to stored articles.

Storage life 储存期限
Storage time should be reduced to the minimum through programmed rotation. When it is not possible to avoid long term storage, it is necessary that the user, as indicated in ISO 8331, carries out a complete check of the hose before its use according to the following criteria:
- maximum two years storage for assembly;
- maximum four years storage for hoses.
当不能够避免长期储存,如ISO 8331所示,用户必须根据以下标准,在使用前对软管做完整检查:
- 最高2年的储存,胶管总成件;
- 最大4年存储,仅胶管。

Temperature and humidity 温度和湿度
The best temperature for the storage of rubber hoses varies from 10 to 25 degrees centigrade. Hoses should not be stored at temperature
above 40°C or below 0°C. When the temperature is below -15°C it is necessary to take precautions when handling. Hoses should
not be stored near sources of heat nor in conditions of high or low humidity. A humidity level of a maximum of 65% is recommended.

Light 光亮
Hoses must be stored in dark places, avoiding direct sun light or strong artificial light. Should store rooms have windows or glass openings,
these must be screened with suitable filters.

Oxygen and ozone 氧化和臭氧
Hoses should be protected from circulating air by suitable packing or by storage in air-tight containers. As ozone has a particularly aggressive
action on all rubber products, the store house must not contain material producing ozone like devices under high electrical tension,
electric engines or other materials provoking sparks or electric arcs.
软管应通过合适的包装防止空气循环,或储存在密封的容器中。由于臭氧对所有橡胶制品有特别侵蚀作用,储存室内不能存有产生臭氧的材料, 比如高张力的电气设备,电动发动机或其他挑起火或电弧材料。

Contact with other materials 与其他材料接触
Hoses should not come into contact with solvents, fuels, oils, greases, volatile chemical mixtures, acids, disinfectants and other organic
liquids in general. Furthermore direct contact with some metals (for example manganese, iron, copper and its alloys) and relative mixture
exercise harmful effects on some types of rubber. Contact with PVC and creosote impregnated timber or fabrics should be avoided.
管子不应该接触到溶剂,燃料,油,润滑脂,挥发性化学混合物,酸,消毒剂和其他一般的有机液体接触。而且直接接触某些金属(例如锰,铁,铜及其合金)和相对的混合物对橡胶是 有害影响。应避免与PVC和木焦油浸渍木材或织物接触。

Heat sources 热源
The temperature limits given in point dedicated to temperature and humidity must be respected. When this is impossible, it is necessary to use a thermic shield at a distance not less than one meter.

Electric or magnetic field 电场或磁场
Variation in electric or magnetic fields must be eliminated in store houses as these could provoke currents in metal coupling, heating them.
Similar fields could be caused by high-tension cables or high frequency generators.

Storage conditions 储存条件
Hoses must be stored in a relaxed condition free from tension, compression or other deformation and contact with objects that could pierce or cut must be avoided. It is preferable to store hoses on special shelves or on dry surfaces. Coiled hoses must be stored horizontally avoiding piling. When this is not possible the height of the piles must be such to avoid permanent deformation of hoses stored underneath.
The inside diameter of the coil, during the storage, must be such as to not compromise the performances of the products. In particular, this diameter must not have value less than those indicated by the manufacturers. It is advisable to avoid storing coiled hoses on poles or hooks. Furthermore it is advisable to store hoses to be delivered straight, horizontally, without bending.

Rodents and insects 鼠类和昆虫
Hoses must be protected from rodents and insects. When such a risk is probable adequate precautions must be taken.

Marking or packaged items 标志或包装
It is advisable that hoses are always easy to identify even if packed.

Exit from storage 出库
Prior to delivery hoses must be checked for integrity and must correspond to the required use. After long storage if couplings are not clipped, swaged or built-in, it is necessary to check that locking collars are tight.

Return to storage 退回存储
Hoses that have been used must be free from all substances prior to storage. Particular attention must be paid when abrasive or similar substances have been conveyed. After cleaning, the hose must be checked for integrity.

Handling 搬运
Hoses must be moved with care avoiding knocks, dragging over abrasive surfaces and compression. Hoses must not be pulled violently
when twisted or knotted. Heavy hoses, normally delivered in a straight line, must be laid on special supports for transport. Should wood
supports be used these must not be treated with creosote or painted with substances which could damage the rubber.
软管必须小心移动,避免敲击,拖过磨料表面和压缩。软管扭曲或打结时,不得猛烈拉提。 重型软管,一般直线传送,必须放在特殊的支撑物上。 建议使用木料支撑,但是那些经过木焦油处理或涂有可能会损坏橡胶物质的木料不可使用。

Bending radius 弯曲半径
Installation underneath the minimum bending radius reduces the life of the hose considerably. Moreover it is necessary to avoid bending at fitting ends.

Torsion 扭力
Hoses are not manufactured to work in torsion, except for specific purposes.
