Product Description

Concrete Mixer Truck PV22 Hydraulic Pump for Danfoss: A Comprehensive Description
I. Introduction
The PV22 hydraulic pump for concrete mixer trucks within the Danfoss system is a key element in the concrete mixing process during transportation. It provides the essential hydraulic power to drive the mixing drum, ensuring the quality and uniformity of the concrete mixture.
II. Design and Construction
A. Housing
The housing of the PV22 pump is engineered for durability. Made from corrosion - resistant materials, it can withstand the harsh environment of construction sites, including exposure to moisture, dust, and chemicals. It also has the strength to endure the mechanical stress from the truck's movement and the vibration of the mixing drum. The housing features precisely designed connection ports and mounting points for seamless integration into the truck's hydraulic system.
B. Internal Components
1. Pistons
The pistons are precision - machined from high - strength materials like hardened steel alloys. They are designed to fit tightly within the cylinders to minimize hydraulic fluid leakage. The smooth surface of the pistons reduces friction during reciprocating motion, enhancing the pump's efficiency and prolonging piston life. Their size and shape are optimized to generate the required pressure and flow rate for the mixer truck's hydraulic system.
2. Cylinders
The cylinders of the PV22 pump are crafted with high precision. Made from materials capable of withstanding high - pressure environments, their inner walls are machined to tight tolerances and often have special surface treatments. These treatments improve 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.
3. Valve System
The valve system consists of inlet, outlet, and pressure - control valves. The inlet valves allow hydraulic fluid to enter the pump smoothly from the reservoir, preventing air from being drawn in. The outlet valves direct pressurized fluid to the hydraulic motor of the mixing drum, handling high - pressure conditions with precision. The pressure - control valves constantly monitor and regulate the pressure within the pump to prevent over - or under - pressure, safeguarding the pump and other components.
III. Operating Principle
A. Intake Stroke
During the intake stroke, the pistons create a low - pressure area in the cylinders. This causes hydraulic fluid to flow from the reservoir through the inlet valves. The design ensures seamless fluid intake, with the pistons and inlet valves coordinated to prevent disruptions. Special features minimize the entry of air bubbles into the fluid.
B. Compression and Discharge
After fluid enters the cylinders, during the compression stroke, the pistons move towards each other, increasing the pressure. The pressurized fluid is then forced out through the outlet valves to the mixing drum's hydraulic motor. The pressure generated is sufficient to overcome the resistance of the mixing drum, including the weight of the concrete and friction in the drum bearings.
C. Pressure Regulation
The pressure - control valves are active during operation. If the pressure exceeds the preset maximum, the valves open to allow some fluid to bypass back to the reservoir or a lower - pressure area. If the pressure drops below the minimum, the pump adjusts to increase the pressure, ensuring the hydraulic motor has enough power.

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. The pump should be able to handle the demands of continuous use, provide consistent performance, and require minimal upkeep to maintain optimal operation.

Q4: How often should the hydraulic pump be maintained or serviced?
A4: The frequency of maintenance or servicing for a mixer truck hydraulic pump depends on its usage and the manufacturer's recommendations. Regular checks and inspections should be performed to ensure the pump is operating correctly and free from leaks or wear. Additionally, filters and other components may require periodic replacement to maintain optimal performance. Following the manufacturer's maintenance schedule is crucial to extend the pump's lifespan and prevent unexpected downtime.

Q5: What materials are typically used in the construction of mixer truck hydraulic pumps?
A5: Mixer truck hydraulic pumps are typically constructed using high-grade materials such as cast iron or steel for the casing and internal components. These materials are chosen for their strength, durability, and resistance to wear and corrosion. Sealing materials, such as O-rings and gaskets, are often made of elastomers or polymers that can withstand the high-pressure environment and prevent leaks.

Q6: How does the hydraulic pump affect the overall performance of the mixer truck?
A6: The hydraulic pump plays a crucial role in the overall performance of the mixer truck. A reliable and efficient pump ensures consistent mixing, which is essential for producing high-quality concrete or other materials. If the pump is not operating correctly, it can lead to mixing inconsistencies, reduced production rates, and even mechanical issues with the mixer truck. Therefore, maintaining a well-functioning hydraulic pump is essential for maximizing the mixer truck's performance and uptime.
