Concrete Mixer Truck PV110 Hydraulic Pump for Danfoss: A Technical Description
I. Introduction
The PV110 hydraulic pump is a crucial component in concrete mixer trucks within the Danfoss system. It is specifically designed to provide the necessary hydraulic power to drive the mixing drum, ensuring the proper mixing of concrete during transportation. This pump's performance directly impacts the quality and consistency of the concrete being transported.
II. Design and Construction
A. Housing
The housing of the PV110 pump is a robust and durable structure. Made from high - quality materials with excellent corrosion resistance, it can withstand the harsh environment of construction sites. It is constantly exposed to elements such as moisture, dust, and chemicals. Additionally, the housing is engineered to endure the mechanical stress caused by the truck's movement and the vibrations of the mixing drum. It features precisely designed connection ports and mounting points for seamless integration into the truck's hydraulic system. These ports ensure a proper connection with the hydraulic lines, preventing leaks and maintaining the integrity of the system. The mounting points provide stable support during operation.
B. Internal Components
1. Pistons
The pistons of the PV110 pump are precision - machined to high standards. They are typically made from hardened steel or specialized alloys with outstanding wear - resistance properties. The design ensures a snug fit within the cylinders, minimizing the leakage of hydraulic fluid. The surface of the pistons is highly polished to reduce friction during their reciprocating motion. This not only enhances the efficiency of the pump but also extends the lifespan of the pistons. Their size and shape are optimized to generate the required pressure and flow rate for the mixer truck's hydraulic system. The pistons are carefully balanced to ensure stable operation under high - pressure conditions.
2. Cylinders
The cylinders of the PV110 hydraulic pump are crafted with great precision. They are made from materials that can withstand high - pressure environments. The inner walls of the cylinders are machined to very tight tolerances and often have special surface treatments. These treatments enhance the smoothness of the walls, reducing friction and providing an effective seal with the pistons. The cylinders support the pistons throughout their stroke, enabling efficient transfer of hydraulic fluid during both the compression and expansion phases of the pump's operation. This ensures a continuous and reliable flow of fluid within the system.
3. Valve System
The valve system of the PV110 pump is a complex and vital part of its design. It consists of inlet valves, outlet valves, and pressure - control valves. The inlet valves are responsible for allowing the hydraulic fluid to enter the pump from the reservoir. They are designed to open smoothly and without obstruction, ensuring a continuous and laminar flow of fluid. To prevent air from being drawn into the system, the inlet valves incorporate specific features. The outlet valves direct the pressurized fluid from the pump to the hydraulic motor that drives the mixing drum. These valves are built to withstand high - pressure conditions and open and close with great precision to control the flow of fluid. The pressure - control valves play a crucial role in maintaining the stability of the hydraulic system. They constantly monitor the pressure within the pump and adjust the flow of fluid as needed to prevent over - pressure or under - pressure situations, protecting the pump and other components from potential damage.
