How to improve Sandblasting hose The service life of sand blasting hose will be greatly shortened if it is not properly used. In practice, the damage of large diameter sand blasting hose is caused by improper use. Now, let's give you a detailed introduction of Laizhou Qiyuan Plastic Products Co., Ltd

1. Improper selection of the amount and speed of buckling during the assembly of the sandblasting hose and the joint, or improper selection of the structure, material and size of the joint, may lead to too tight or too loose pressure between the sandblasting hose and the joint, resulting in early damage at the joint. If the amount of crimping is too small during assembly, that is, when the pressure between the joint and the sandblasting hose is too loose, the hose may come out of the joint at the beginning of use under the action of oil pressure; During the assembly of sandblasting hose and joint, if the pressing speed is too fast, it is easy to form internal rubber damage and steel wire layer fracture, which will cause premature damage of sandblasting hose in use. In addition, unreasonable joint design and poor processing quality will also cause damage to the inner glue; If the joint material is not properly selected, it is easy to deform in the process of crimping, which will affect the quality of crimping and shorten the life of sand blasting hose.

2. Be impacted by frequent and violent pressure. The bursting of sand blasting hose is not caused by too much static pressure, but is related to the violent level and frequency of pressure impact. During the operation of construction machinery, the oil pressure in the oil pipe will repeatedly rise or fall suddenly, which will cause frequent pressure shocks to the oil pipe, causing the oil seal damage of each part to intensify Sandblasting hose Bubbles and cracks as well as loose leakage of pipe joints are present. Therefore, the valve rod shall not be pulled too hard during operation and must be gentle.
