Along with the rapid development of science and economy, the manufacturing technology of concrete pump trucks has made great progress, and promoted the continuous maturity of the commodity concrete industry. Nowadays, in the pursuit of construction efficiency, concrete pump truck are more and more accepted by the users in the construction market. The concrete pump truck is the machine that uses pressure to boom the concrete to construction point along the pipe continuously. To improve the working efficiency of the concrete pump truck, the maintenance is essential after put into production. As a trusted concrete pump truck manufacturer, we have some maintenance tips for construction projects.
The preheat for concrete pump truck is mainly for pumping hydraulic systems, this is because, at low temperatures, the viscosity of the hydraulic oil increases and the fluidity decreases, resulting in the flow resistance in the pipe increased. In the state of high viscosity of the hydraulic oil, the hydraulic pump has oil absorption difficulties in the working state of the overloading, and even occurs “pumping air” phenomenon, and the hydraulic pump may be excessively worn due to poor lubrication. Therefore, before the formal construction of the concrete pump trucks for sale, it must be sufficient preheating. Especially in the winter construction phase, due to the original lower temperature of the hydraulic system, the upper garment preheating is even more important.
