The quality of the concrete pump 's cylinder plating directly affects the service life and work efficiency. It can be said that the main oil cylinder is the main component of the finished concrete pump . The surface of the main oil cylinder is smooth without trachoma, so that it can be used smoothly in use. The process of plating is the most important process. The number of wires is the most important. The normal standard wire number can not only make the main cylinder smooth and shiny, but also extend the service life; it is very smooth under working conditions, and it also prolongs the service life of the oil seal on the head of the cylinder. Waste hydraulic oil. However, if the number of plating wires is not enough, it will not only affect the service life, but also wear the oil seal early, and the hydraulic oil will be lost and wasted, which will affect the work progress. The surface of the main cylinder can not be trachoma. A small trachoma will cause great trouble. The oil seal will wear out early and the hydraulic oil will be lost. What's more, it will often fail during use, making normal work impossible. Therefore, the plating process of the main cylinder of the concrete is very important.
