How to Select a Mechanical Seal for a Centrifugal Pump. May 26, 2020; Every centrifugal pump needs some way to prevent the product liquid from leaking past the spinning drive shaft. The method of sealing can be as simple as packing rope impregnated with graphite into a “packing box” and as complex as enclosing the whole pump in a chamber .
In the realm of petroleum equipment manufacturing, the adjustment screw plays a crucial role in the commencement of control for concrete pumps. Specifically, the adjustment screw is vital in regulating the flow compensator of the concrete pump, ensuring optimal performance and efficiency. In this article, we will delve into the process of adjusting the flow compensator using the adjustment screw, providing detailed instructions and insights for hydraulic pump pressure adjustment and output pressure adjustment.
If standing by the control handles the pressure relief adjustment screw for the hydraulic pump is located on the left side of the machine. The The pressure relief adjustment screw for the drive valve is located on the right side. Set the pressure for the drive valve to 2 psi. pump should be
Hydraulic Pump Pressure Adjustment Instructions
To begin the process of adjusting the hydraulic pump pressure for a concrete pump, it is essential to first locate the flow compensator adjustment screw. This screw is typically found near the hydraulic pump unit and is used to regulate the flow of hydraulic fluid, thereby controlling the pressure output of the pump.
1. Loosen the Flow Compensator Adjustment Screw Lock Nut: Using a 7/16 inch open-end wrench, carefully loosen the lock nut that secures the adjustment screw in place. This will allow you to make adjustments to the flow compensator more easily.
2. Turn the Adjustment Screw: Once the lock nut is loosened, you can now turn the adjustment screw to increase or decrease the hydraulic pump pressure. Turning the screw clockwise will increase the pressure, while turning it counterclockwise will decrease the pressure.
3. Monitor Pressure Output: As you make adjustments to the flow compensator, it is crucial to monitor the pressure output of the hydraulic pump. Use a pressure gauge to ensure that the pressure is within the recommended range for optimal performance.
4. Secure the Adjustment Screw: Once you have achieved the desired hydraulic pump pressure, tighten the lock nut on the adjustment screw to secure it in place. This will prevent any unintended changes to the pressure settings.
Hydraulic Pump Output Pressure Adjustment
In addition to adjusting the hydraulic pump pressure, it is also important to consider the output pressure of the pump. The output pressure determines the force at which the concrete is pumped through the system, affecting the efficiency and effectiveness of the pumping process.
1. Follow the Same Steps for Flow Compensator Adjustment: The process for adjusting the output pressure of the hydraulic pump is similar to that of adjusting the pressure. Loosen the lock nut on the flow compensator adjustment screw and turn the screw to make the necessary adjustments.
2. Consider Flow Rate and Pumping Distance: When adjusting the output pressure, it is important to consider factors such as the desired flow rate and the distance the concrete needs to be pumped. These factors will influence the optimal output pressure for the pump.
3. Test the Pumping System: After making adjustments to the output pressure, test the pumping system to ensure that the concrete is being pumped at the desired rate and pressure. Make any additional adjustments as needed to achieve the desired results.

1. Fill the pump volute full of water. NOTE: If this is not a self-priming pump, you will have to repeat this operation each time you restart the pump for another pumping cycle. If the pump is self-priming, just the initial fill of the volute is all that is necessary. Any further restarts of the pump will automatically restart the prime. 2.
