Water tank wire drawing machine for water quality

The Water Tank Wire Drawing Machine has the following special requirements for water quality:

Cleanliness requirements

The water in the water tank of the water tank wire drawing machine needs to be clean. The water cannot contain a large amount of solid impurities, such as sand, metal debris, etc. Because these impurities may adhere to the surface of the wire during the wire drawing process, affecting the quality of the wire. For example, when drawing high-precision steel wire for mechanical manufacturing, if there are impurities in the water, scratches may appear on the surface of the steel wire, reducing the strength and surface finish of the steel wire. Moreover, impurities may also block the cooling pipes or damage the components of the circulation system such as the water pump, affecting the normal operation of the equipment.

pH requirements

The pH value of water should be kept within a certain range. Generally speaking, the water in the water tank of a water tank wire drawing machine should be neutral or weakly alkaline. If the water is too acidic, it may corrode the metal parts of the equipment, such as the water tank itself, cooling pipes, and molds. In an acidic environment for a long time, metal parts will rust and corrode, shortening the service life of the equipment. If it is a strong alkaline environment, it may affect the performance of the lubricant, and may also chemically react with certain wires, damaging the wires.

Hardness requirements

The hardness of water is also an important factor. Water with too high hardness contains more calcium, magnesium and other ions, which may form scale in the water. When scale is deposited in the water tank, cooling pipes and heat exchangers, it will reduce the heat exchange efficiency. For example, when scale forms on the wall of the heat exchanger, the heat exchange between the coolant and the external cooling medium will be hindered, so that the coolant cannot be effectively cooled, resulting in excessively high temperatures during the wire drawing process, affecting the wire quality and equipment performance.

Temperature requirements

The temperature of the water in the water tank needs to be controlled within an appropriate range. Although heat is generated during the wire drawing process and the water temperature rises, if the initial water temperature is too high, it will affect the cooling effect. Generally, the water temperature should be kept within a range that can effectively take away the heat, which is also related to factors such as the wire drawing material and speed. For example, when drawing some temperature-sensitive materials, a lower and more stable water temperature can better ensure the quality of the wire and the accuracy of the wire drawing.

Chemical substance content requirements

The water cannot contain any chemical substances that are harmful to the wire or equipment. For example, the water cannot contain a large amount of chloride ions, because chloride ions can cause serious corrosion to metal equipment. At the same time, it should also avoid containing chemical substances that may react chemically with the wire, such as some strong oxidizing substances, so as not to affect the quality and performance of the wire.
