Generally, if the gunite machine fails or can not be used, only the relevant parts of the gunite machine need to be replaced regularly. Everyone knows that the parts of the gunite machine belong to the vulnerable parts. In the long-term work, new related parts will often be replaced. If the quality of the replaced parts is not good enough, the same failure will continue to occur and affect the working efficiency and service life of the gunite machine. How can we choose the right parts of the gunite machine with good quality? Next, we will explain how to choose the parts of the gunite machine.
1. Selection method of nozzle, which is a part of gunite machine. Shotcrete pipe is an important pipeline for slurry transportation. Its quality will reduce slurry loss, and it is also an important accessory to improve work efficiency. When choosing, we should ask whether the manufacturer is made of high wear-resistant synthetic rubber and nano-materials, and observe the inner and outer layers of the nozzle section to see whether steel wire reinforced layer and corrosion-resistant outer rubber layer are used. If they are all in line, you can be assured to buy. If you buy the product through the Internet, you can consult the relevant manufacturers, and check the relevant problems after the goods are delivered. If they are not in line, they can be returned, so as to avoid being unable to return the goods due to use.
2. Selection method of sprinkler accessories-sprinkler head. When choosing the sprinkler head, we should choose the high wear resistant sprinkler made of polyurethane material. Generally, the overall color is yellow and transparent. Through light, we can observe the crystal and transparent outside of the sprinkler head, which shows that the quality is good. We should also pay attention to the flexibility of the sprinkler head. When purchasing these details, we should ask the manufacturer clearly before purchasing.
3. Selection method of steel liner for gunite shotcrete machine accessories. When choosing the steel liner, we must pay attention to the sealing of the upper and lower grinding plates. Because the wear is faster in use, we must pay attention to whether the products are made of high manganese steel or stainless steel when choosing the steel liner, because the two materials have high wear resistance.
4. Selection of tapered casing. Conical sleeve is usually made of polyurethane material, which has the characteristics of wear resistance, compression resistance and not easy to break. When choosing conical sleeve, fold it slightly with your hand to see if there are small cracks in the creases. If there are cracks, it shows that the product quality is not up to standard and the wear resistance effect is not good. It is recommended not to buy this type of product. High-quality conical casing, when freely folded by hand, the creases will not appear small slits, and after recovery, the creases will gradually disappear and will not deform.
5. Selection method of rubber sealing plate. As the name implies, rubber is the material used in rubber sealing plate, although the product materials are the same, but the quality of rubber is different, the service life of the produced sealing plate is also different. Rubber sealing plate grouting machine fittings belong to the more rigorous process products, so in the selection, we must pay attention to the quality of sealing plate and product process. Quality can be seen through careful observation, poor quality sealing plate shows that there will be pits, naked eye observation is difficult to find, this low-quality rubber production sealing plate, will lead to poor sealing effect, resulting in the efficiency of the gunite machine decreased and related costs increased.
