LL22-20 Concrete Pump

The secondary structural column pump is widely used in various construction projects, municipal engineering, tunnel engineering, mines, petrochemical engineering and agricultural water conservancy systems for compaction grouting, chemical grouting, foundation reinforcement, waterproofing and plugging, soil anchor construction, Rotary injection construction, drilling construction, tree root piles, double overflow grouting, thunder grouting, rotary injection piles, etc. The advantages of the secondary structural column transfer pump: the power system, the hydraulic system and the pumping system are reasonably matched, and the power of the motor can be effectively exerted. High material absorption, the actual pumping efficiency reaches more than 80% of the theoretical value. The configuration is more optimized, and the imported hydraulic parts and electrical components are used, which greatly improves the reliability of the equipment. The unique distribution oil circuit buffer technology ensures that the S tube swings in place and prolongs the service life of the S tube. The application of high and low voltage switching simplifies the operation mode. The lubricating system adopts forced filtration and pre-pressing dual-pump energy-saving automatic centralized oil supply system, which provides sufficient oil supply and better lubrication effect, and saves consumption by more than 50% compared with ordinary continuous oil injection. The application of new wear-resistant materials and welding processes doubles the service life of commonly used wearing parts. The power system adopts international brand hydraulic main pump, and the motor adopts domestic brand to provide strong power. The unique open hydraulic system and proprietary hydraulic buffer technology of the hydraulic system make the system less impact and less heat when reversing.
