Concrete Mixer Truck PV070 Hydraulic Pump for Danfoss: A Comprehensive Technical Description
I. Introduction
The PV070 hydraulic pump designed for concrete mixer trucks within the Danfoss system is a critical component that enables the efficient operation of these vehicles in the construction industry. This pump is specifically engineered to provide the necessary hydraulic power for the mixing drum, ensuring that the concrete is mixed thoroughly and consistently during transportation. It is designed to withstand the harsh conditions of construction sites and the demanding requirements of the concrete mixing process.
II. Design and Construction
A. Housing
The housing of the PV070 hydraulic pump is a robust structure built to endure the tough environment of a concrete mixer truck. It is typically fabricated from high - quality materials, such as a strong alloy that combines excellent mechanical strength with high resistance to corrosion. This alloy is carefully selected to withstand the continuous vibrations from the truck's movement on rough terrains, as well as the dynamic forces generated during the mixing operation.
The housing's design also considers protection against environmental factors like dust, moisture, and extreme temperature variations. It has a well - thought - out shape and structure to facilitate easy installation within the truck's hydraulic system. The mounting points and connection ports are precisely engineered to ensure proper alignment and a secure connection with other hydraulic components. The outer surface of the housing may be treated with special coatings to further enhance its durability and resistance to wear and tear.
B. Internal Components
1. Pistons
The pistons of the PV070 pump are precision - machined components that play a vital role in the pump's operation. They are usually made from high - performance materials like hardened steel alloys with outstanding wear - resistance properties. The design of the pistons ensures a tight fit within the cylinders, minimizing the clearance to prevent internal leakage of hydraulic fluid.
The surface of the pistons is finished to a high level of smoothness, which reduces friction during their reciprocating motion. This low - friction design not only improves the efficiency of the pump but also helps to extend the lifespan of the pistons. The size and shape of the pistons are optimized to generate the required pressure and flow rate for the concrete mixer truck's hydraulic system. Each piston is carefully balanced to ensure stable operation under the high - pressure and high - speed conditions that are common during the mixing process.
2. Cylinders
The cylinders of the PV070 hydraulic pump are crafted with great precision. They are made from materials that can withstand high - pressure environments and maintain their structural integrity over time. The inner walls of the cylinders are machined to very tight tolerances and are often treated with special coatings or surface treatments.
These treatments enhance the smoothness of the cylinder walls, reducing friction and providing an effective seal with the pistons. The cylinders are designed to provide reliable support to the pistons throughout their entire stroke, enabling efficient transfer of hydraulic fluid during both the compression and expansion phases of the pump's operation.
3. Valve System
The valve system of the PV070 pump is a complex and crucial part of its design. It consists of different types of valves, including 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 features that minimize the risk of cavitation.
The outlet valves direct the pressurized fluid from the pump to the hydraulic motor that drives the concrete 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 vital 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. This helps to protect the pump and other components of the hydraulic system from potential damage.

FAQ
Questions you maybe inquiry
Q1: What is the main function of a mixer truck hydraulic pump?
A1: The mixer truck hydraulic pump's main function is to provide the necessary power and flow rate to mix the materials efficiently within the mixer truck's drum. It generates high-pressure hydraulic fluid flow, which drives the mixing mechanism to combine various materials uniformly.
Q2: How does a hydraulic pump differ from other types of pumps used in mixer trucks?
A2: A hydraulic pump differs from other types of pumps used in mixer trucks in its ability to generate high-pressure fluid flow. It specifically converts mechanical energy into hydraulic energy, providing the necessary force to mix dense materials effectively. Other pumps, such as electric or pneumatic pumps, may not provide the same level of power and pressure required for mixer truck applications.
Q3: What are the key features of a high-quality mixer truck hydraulic pump?
A3: A high-quality mixer truck hydraulic pump should possess several key features. These include durability, efficiency, high-pressure capabilities, and low maintenance requirements.
