How to choose a good Zinc alloy wire rope manufacturer is a matter that all buyers seriously consider. Whether it is a newbie who has just entered the industry or a boss who is not bad money, they all have such concerns. What kind of Zinc alloy wire rope manufacturer is good to choose?
In addition, in order to reduce the wear with the sheave groove, it is necessary to use an 8-strand structure, and the strength of the outer wire rope in the strand is lower than the strength of the Zinc alloy wire rope in the inner strand.
Zinc alloy wire rope is made of high quality zinc alloy, which can reach high strength after repeated cold drawing and heat treatment. Workplaces such as wet or open air environments can use wire ropes twisted from galvanized steel wires to enhance rust resistance.
As the full recovery of the global economy and the vigorous development of the domestic economy, nylon coated stainless steel wire, as the production of daily necessities, has expanded its application scope in the fields of petroleum, chemical industry, bandage tube, boiler insulation and antifreeze, civil construction, supplies, etc. in recent years. Demand is growing.
The structural damage of Nylon coated wire rope is the primary factor affecting the actual performance and service life of the wire rope. Careful analysis of the actual operating conditions, scientific and rational selection of the wire rope structure is the basis for improving the performance and life of the wire rope.
Generally, nylon coated stainless steel wire rope products will produce certain wear, and the wear is also divided into external surface wear and internal surface wear.

1. It is strictly forbidden to use the new customized galfan wire rope directly at high speed and heavy load: Do not use the new customized galfan wire rope directly at high speed and heavy load immediately, but run it under low speed and medium load conditions for a period of time to adapt the new rope to the state of use Then, gradually increase the running speed of the customized galfan wire rope and increase the lifting load, that is, the new wire rope must go through the initial running-in stage before high-speed and heavy-duty operations.

2. It is strictly forbidden to use galfan wire rope to jump out of the groove when the wire rope is used in conjunction with the pulley. If the wire rope is still used after it falls off the wheel groove, it will produce squeezing deformation, kinking, wire breakage, and strand breakage, which will seriously shorten the service life of the wire rope. If the rope breaks, it will often bring catastrophic consequences.

3. Extrusion deformation of galfan wire rope is strictly prohibited: the steel wire rope should not be squeezed strongly when in use, so as to avoid the deformation of the wire rope, resulting in structural damage and early wire breakage (the brittle layer structure of martensite will appear on the surface of the wire), breakage Strands or even breaks the rope, which significantly reduces the service life of the wire rope and endangers the safety of operations.

4. It is strictly forbidden for galfan wire rope to rub against other objects when running at high speed: When the wire rope is running at high speed, avoid friction with other objects outside the non-matching wheel groove. Because at high speeds, the instantaneous frictional heat generated when the wire rope and these objects are running with each other can cause a martensite structure on the surface of the wire. Although this change in the structure cannot be distinguished by the naked eye, it causes the wire to break early. The main reason.

5. It is strictly forbidden to wind galfan wire rope randomly: When the wire rope is wound on the drum, it should be arranged as neatly as possible. If the wire rope is entangled randomly, the wire rope structure will be damaged due to mutual extrusion during work, resulting in early wire breakage, which directly affects the service life of the wire rope. It is strictly forbidden to use the wire rope with overload: if the wire rope is used with overload, it will rapidly aggravate its squeezing deformation. The degree of wear between the inner steel wire and the outer steel wire and the matching wheel groove brings serious harm to the safety of operation and shortens the service life of the pulley.

6. It is strictly forbidden for galfan wire rope to be subjected to severe shocks and vibrations: during the use of the wire rope, if the running speed frequently changes rapidly, it will cause an impact load. Although each impact is only an instant load, it implies great harm. When the impact load exceeds the allowable working stress of the wire rope, the rope will break. Even if the impact load does not necessarily cause the wire rope to break, multiple impacts will severely shorten the service life of the wire rope. For the steel wire rope that has been used for a period of time, compared with the new rope, the impact resistance will be lower due to the smaller stretchability.

7. Running speed: The lower the running speed, the less damage to the customized galfan wire rope. As the running speed increases, the damage of the wire rope increases accordingly. For this reason, it is necessary to avoid sudden speed changes during operation, and avoid sudden and violent loading and violent braking, which can reduce the damage of the customized galfan wire rope. Compared with working under medium load at high speed, the life of steel wire rope is much longer.
