Why do Atos piston pumps need to turn on reflux

1、 Atos ATOS plunger pump is one of the positive displacement pumps, which is a hydraulic pump that uses a plunger to reciprocate liquid through a valve. In hydraulic transmission systems, plunger pumps are typically used to provide positive pressure fluid. It is composed of a plunger, crankshaft mechanism, upper and lower piston chambers, ball valve, spring, inlet and outlet, and accessories. Piston pumps have the advantages of simple structure, stable and reliable operation, and have been widely used in many fields.

2、 The water inlet effect of Atos ATOS plunger pump

The inlet of the Atos ATOS plunger pump is an important component of the hydraulic transmission system. Its function is to introduce low-pressure liquid into the plunger pump for pumping. The inlet of a plunger pump is usually connected to the oil tank. When pumping is required, the liquid enters the pump body of the plunger pump through the inlet, undergoes a series of pumping operations, and finally reaches the target position. Therefore, the function of the plunger pump's water inlet is to ensure that the liquid can smoothly enter the pump body and complete the pumping work smoothly.

3、 The water outlet function of Atos ATOS plunger pump

The outlet of the Atos piston pump is another important component of the hydraulic transmission system. Its function is to transfer the high-pressure liquid inside the pump body and provide it to the hydraulic equipment for operation. The outlet of a plunger pump is generally connected to hydraulic components such as hydraulic cylinders and motors. When the hydraulic oil inside the pump body is subjected to a certain pressure, it flows from the outlet to these components, causing them to move. Therefore, the function of the plunger pump's water outlet is to transfer the high-pressure hydraulic oil inside the pump body to the hydraulic components, providing power support.

4、 Return water effect of Atos ATOS plunger pump

The return water of the Atos piston pump is another important component of the hydraulic transmission system. Its function is to return the unused hydraulic oil inside the pump body to the oil tank for further utilization. In hydraulic transmission systems, hydraulic components often only require a portion of hydraulic oil to complete their movement, so a portion of the hydraulic oil inside the pump body may not be used up. At this point, the function of the plunger pump return water is to return the unused hydraulic oil to the oil tank for new pumping work. Therefore, plunger pump return water is a very important hydraulic control method that can effectively complete the use and recovery of hydraulic oil.

5、 Starting from the working principle of the plunger pump, this article provides a detailed introduction to the functions of the inlet, outlet, and return of the plunger pump. As a common fluid conveying equipment, plunger pumps have the characteristics of high pressure, stable pump capacity, and long service life, and have been widely used in hydraulic transmission systems.

1、 What is a plunger pump?

A plunger pump is a type of hydraulic pump that generates a certain pressure and flow rate of liquid through the action of the distribution plate or cam of the pump through the plunger, thereby driving mechanical equipment or performing hydraulic system work.

2、 Why do Atos piston pumps need to have reflux?

In the working process of a plunger pump, in order to ensure the normal operation of the pump, it is necessary to pump the liquid back into the low-pressure circuit of the pump, and this process is called reflux. Opening the reflux can ensure the smooth and stable operation of the plunger pump, and is beneficial for maintaining the service life of the pump.

Specifically, the reflux function of a plunger pump mainly serves the following purposes:

1. Balance system pressure: The pressure generated by the plunger pump during operation will push the liquid into the pipeline. If there is no backflow, the pressure will continue to rise, which may cause pipeline rupture. Reflux can balance the system pressure and ensure the normal operation of the hydraulic system.

2. Protecting the pump body: If the reflux is not turned on, during the operation of the pump, the poor sealing between the plunger and the pump body can easily cause excessive pressure inside the pump body, resulting in the pump body bursting. Reflux can reduce the occurrence of excessive pressure inside the pump body and prolong its service life.

3. Reduce the temperature of the pump: During the operation of the plunger pump, a certain amount of frictional heat and liquid resistance will be generated, causing the temperature of the pump body to continuously rise. However, reflux can pump some of the liquid back into the low-pressure loop, thereby taking away some of the heat and reducing the temperature rise of the pump body.

3、 How to determine the return flow?

In practical applications, the reflux rate needs to be determined based on the specific situation of the hydraulic system. Setting the reflux rate too high or too low can affect the normal operation of the plunger pump.

If the reflux rate is set too high, it will waste liquid and cause energy waste; If the reflux rate is set too low, it will cause poor reflux, increase the working intensity of the pump, and shorten the service life of the pump. Therefore, in practical applications, adjustments need to be made to ensure the reasonable setting of the reflux volume.

【 Conclusion 】

Atos ATOS plunger pump is a common hydraulic pump that requires the opening of reflux during its operation. Opening the reflux can ensure the smooth and stable operation of the plunger pump, and is beneficial for maintaining the service life of the pump. In practical applications, the reflux rate needs to be determined according to the specific situation of the hydraulic system to ensure the normal operation of the pump.

1、 The role and importance of pump reflux

Pump reflux, in simple terms, refers to setting up a reflux path between the outlet and inlet of the pump. This practice is mainly aimed at preventing blockages or overloads during pump operation, ensuring the normal operation of the pump and extending its service life. Its role is mainly reflected in the following aspects:

1. Stable pump operation: During the operation of the pump, there may be some unexpected situations, such as a sudden increase in solid particles in the conveying medium, resulting in a sudden increase in the output pressure of the pump. At this point, the reflux system can automatically adjust to allow some of the medium to reflux back to the inlet, thereby reducing the output pressure of the pump and protecting it from damage.

2. Preventing cavitation: When the pressure at the pump inlet is lower than the saturated vapor pressure of the medium, bubbles will be generated in the medium, and these bubbles will quickly collapse in the high-pressure area, causing cavitation to the pump. Reflux can increase the pressure at the inlet and prevent the occurrence of cavitation.

3. Energy saving and environmental protection: Through reasonable reflux design, energy consumption can be reduced and unnecessary waste can be minimized while meeting process requirements. Meanwhile, reflux can also prevent the medium from staying stagnant in the pipeline for a long time, reducing the deterioration and pollution of the medium.

2、 The principle of pump reflux

The principle of pump reflux is mainly achieved by setting a bypass valve or regulating valve between the outlet and inlet of the pump. When the output pressure of the pump exceeds the set value, the bypass valve will automatically open, allowing some medium to flow back to the inlet of the pump, thereby reducing the output pressure of the pump. This method can effectively protect the pump from overload damage and ensure stable operation of the pump.

In addition, the reflux system can be adjusted according to actual needs. For example, when it is necessary to reduce the flow rate of the pump, it can be achieved by adjusting the opening of the reflux valve. This can meet the process requirements and avoid energy waste.

3、 Basic concepts and steps of pump circuit design

The design of the pump circuit is a crucial step in ensuring the effective operation of the pump reflux system. The basic concept and design steps are as follows:

1. Determine design objectives: Clearly define the functions that the circuit needs to achieve, such as voltage stabilization, flow regulation, etc.

2. Choose appropriate pumps and valves: Select appropriate pumps and valves according to the actual situation to ensure that they can meet the process requirements.

3. Reasonable pipeline layout: Design a reasonable pipeline route, reduce bends and resistance, and improve reflux efficiency.

4. Set up control system: Set up an automatic control system as needed to achieve automatic adjustment of pump reflux.

In summary, pump reflux plays a crucial role in the operation of the pump. Through reasonable design and implementation, the normal operation of the pump can be effectively protected, energy utilization efficiency can be improved, and the goal of energy conservation and emission reduction can be achieved.

At the same time, the design of Atos ATOS plunger pump is also a key link to ensure the efficient operation of the pump reflux system, which requires reasonable design and layout according to the actual situation.
