Mixer Truck Hydraulic Pump T90R75 For Danfoss
Introduction
The Mixer Truck Hydraulic Pump T90R75 designed for Danfoss systems is an integral part of the mixer truck's hydraulic infrastructure. It is engineered to meet the specific demands of the concrete mixing process within these vehicles.
Functionality
1. **Powering the Mixing Process**
- The T90R75 pump is primarily responsible for providing the hydraulic power required to rotate the mixing drum of the mixer truck. This rotation is essential for thoroughly mixing the concrete ingredients, including cement, aggregates, water, and additives. The pump ensures that the drum rotates at an appropriate speed and torque to achieve a homogeneous mixture.
- It also supplies hydraulic energy to other related components within the mixer truck. For example, it may power the mechanism that controls the angle and position of the discharge chute during the unloading of concrete. This enables precise and efficient pouring of the mixed concrete at the construction site.
2. **Maintaining Hydraulic System Performance**
- The pump plays a crucial role in maintaining the stability and efficiency of the entire hydraulic system. It ensures a continuous and reliable supply of hydraulic fluid under varying operating conditions. This helps in preventing issues such as pressure drops or inconsistent fluid flow, which could otherwise affect the performance of the mixer truck's hydraulic functions.
Technical Specifications
1. **Displacement**
- The T90R75 pump has a specific displacement value that determines the volume of hydraulic fluid it can displace per revolution. This value is carefully calibrated to match the requirements of the mixer truck's hydraulic system. A proper displacement ensures that the right amount of fluid is delivered to the system components, enabling them to function optimally. For instance, it provides the necessary fluid volume to maintain the desired speed of the mixing drum rotation.
2. **Pressure Rating**
- The pump is designed to handle significant pressures within the hydraulic circuit. During the mixing process, especially when the drum is filled with concrete, there is substantial resistance to the rotation. The T90R75 pump has a high - pressure rating to overcome this resistance and ensure smooth operation. It can generate and withstand pressures sufficient to drive the mixing drum and other hydraulic components under heavy - load conditions.
3. **Efficiency**
- This hydraulic pump is highly efficient in converting mechanical energy from the truck's power source into hydraulic energy. High efficiency means that there are minimal energy losses during the conversion process. This results in reduced fuel consumption and less heat generation within the hydraulic system. Reduced heat generation is beneficial as it helps in prolonging the life of the hydraulic components and maintaining the overall reliability of the system.
Design and Construction
1. **Robust Design**
- The T90R75 pump features a robust design constructed with high - quality materials. It is built to withstand the harsh operating conditions of a mixer truck, including exposure to dust, dirt, vibration, and mechanical shocks. This durability ensures that the pump can maintain its performance over an extended period without frequent breakdowns or the need for excessive maintenance.
2. **Precision - Engineered Components**
- The internal components of the pump are precision - engineered. The gears, pistons, and seals are designed with high - precision manufacturing techniques to ensure smooth operation and minimal friction. This precision - engineered design reduces wear and tear on the components, further enhancing the pump's reliability and lifespan.
Compatibility with Danfoss System
1. **Hydraulic System Compatibility**
- The T90R75 pump is fully compatible with the Danfoss - based hydraulic system of the mixer truck. It has the appropriate hydraulic connections and interfaces that seamlessly integrate with other components such as hoses, valves, and hydraulic motors within the system. This compatibility allows for easy installation and replacement, ensuring that the hydraulic system functions as a cohesive unit.
2. **Control System Compatibility**
- The pump works in harmony with the Danfoss control system. It can receive and respond to control signals from the truck's control panel. This enables operators to have precise control over the speed of the mixing drum and other hydraulic functions. The integration between the pump and the control system allows for optimization of the concrete mixing process according to different job - site requirements and concrete mix designs.

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.
