Hey there! I'm a supplier of the A4VTG71 Mixer Truck Hydraulic Pump. You might be wondering, what's the working principle of this nifty piece of equipment? Well, let's dive right in and break it down.
First off, the A4VTG71 Mixer Truck Hydraulic Pump is a key component in mixer trucks. It plays a crucial role in powering the rotation of the mixing drum, ensuring that the concrete inside is well - mixed and ready for construction work.
Basic Structure
The A4VTG71 pump has a complex but well - designed structure. It consists of a housing, a swash plate, pistons, a cylinder block, and a valve plate. The housing is like the protective shell that holds all the internal components together. It's made of high - strength materials to withstand the high pressures and harsh working conditions.
The swash plate is a vital part. It's an inclined plate that can change its angle. This angle adjustment is what allows the pump to vary its displacement, which we'll talk more about later. The pistons are arranged in the cylinder block. As the cylinder block rotates, the pistons move back and forth due to the interaction with the swash plate.
Working Process
Let's start with the intake phase. When the pump starts operating, the cylinder block begins to rotate. As it rotates, the pistons in the cylinder block move outwards from the center of the block. This movement creates a vacuum in the cylinder bores. The hydraulic fluid from the reservoir is then sucked into these bores through the intake port on the valve plate. It's like a straw sucking up a drink, but in this case, it's hydraulic fluid.
Once the cylinders are filled with hydraulic fluid, the compression phase begins. As the cylinder block continues to rotate, the pistons are pushed back towards the center of the block by the swash plate. This compresses the hydraulic fluid in the bores. The valve plate then directs the compressed hydraulic fluid to the outlet port.
The amount of hydraulic fluid that is pumped out per revolution of the cylinder block is called the displacement. And here's where the swash plate comes in handy. By changing the angle of the swash plate, we can adjust the stroke length of the pistons. A larger swash plate angle means a longer piston stroke, which results in a greater displacement. Conversely, a smaller angle leads to a shorter stroke and less displacement. This variable displacement feature is really useful as it allows the pump to adapt to different operating requirements.
Applications in Mixer Trucks
In a mixer truck, the A4VTG71 pump is connected to the mixing drum through a hydraulic motor. The high - pressure hydraulic fluid from the pump drives the hydraulic motor, which in turn rotates the mixing drum. This continuous rotation ensures that the concrete inside the drum remains in a well - mixed state. Whether it's a small - scale construction project or a large - scale infrastructure build, the A4VTG71 pump helps keep the concrete in perfect condition.
Advantages of the A4VTG71 Pump
One of the biggest advantages is its efficiency. Thanks to the variable displacement design, the pump can adjust its output according to the actual needs of the mixer truck. This means less energy waste and lower operating costs. It also has a high - pressure rating, which allows it to handle the demanding tasks in mixer trucks.
Another advantage is its reliability. The robust construction and high - quality materials used in its manufacturing ensure that it can operate for long periods without major breakdowns. This is crucial for construction projects where downtime can be very costly.
