A bent or too long pipe joint at the oil suction port of the plunger pump can indeed increase the vacuum at the oil suction port. Suction piping design and configuration play a vital role in maintaining efficient and reliable pump operation. The following is the effect of curved or long pipe joints on the vacuum of the oil suction port: 1. Flow Restriction: Bent or improperly aligned fittings can create additional resistance to the flow of oil or liquid into the pump suction. This restriction disrupts the smooth flow path, causing turbulence and pressure drop. As a result, the pump has to work harder to overcome the increased resistance, resulting in lower pressure and increased vacuum at the suction. 2. Increase friction loss: Too long pipe joints will bring more friction loss due to larger surface area and longer flow path. Frictional losses occur as fluid flows through pipes, and these losses are proportional to the length of the pipe. The longer the fitting, the greater the friction loss, which results in a decrease in pressure and an increase in vacuum at the suction port. 3. Risk of cavitation: Increased vacuum at the suction port due to bent or long pipe joints may cause cavitation. Cavitation occurs when the pressure at the suction port falls below the vapor pressure of the fluid, resulting in the formation of vapor bubbles. When these air bubbles burst in areas of high pressure, such as near the pump plunger, it can cause severe pump damage and reduced performance.

Here are some suggestions: 1. Straight and smooth piping: Use straight pipe sections and minimize the number of bends or turns in the suction line. Smooth and properly aligned pipe joints reduce frictional losses and minimize resistance to fluid flow. 2. Optimum pipe length: The pipe joint at the oil suction port is as short as possible while maintaining proper maintenance convenience. Reducing the length of the pipe joint reduces frictional losses and helps maintain a higher pressure at the suction port. 3. Proper pipe size: Make sure the diameter of the suction pipe is sized for the required flow. Undersizing tubing increases fluid velocity, resulting in higher friction losses and increased suction vacuum.

Avoid air leakage: Make sure that all joints and fittings are connected tightly and reliably to prevent air leakage from entering the suction line. Air leaks will reduce vacuum and affect pump performance. 5. Increased priming difficulty: Bent or long pipe joints can make priming the pump more challenging. Priming involves filling the pump and suction line with liquid to remove air and create a continuous flow. Increased drag and turbulence caused by bent or long fittings can hinder the priming process, making it more difficult to establish proper suction and start the pump running. 6. Risk of cavitation damage: As mentioned earlier, increased vacuum at the suction port due to bent or long pipe joints may cause cavitation. Cavitation not only affects pump performance, but can also cause damage to pump components. The collapse of air bubbles can corrode and pit the surfaces of plungers, valves and other internal parts, reducing their efficiency and service life. 7. Pressure drop and flow loss: Bent or long pipe joints can cause pressure drop on the suction line. This pressure drop results in a loss of flow, which reduces the pump's ability to deliver the required amount of fluid. Insufficient flow will affect the pump's ability to meet system requirements and may result in insufficient lubrication or cooling in some applications. 8. Stress on pump components: Misaligned or overly long fittings can place additional stress on pump components. Uneven forces and vibrations caused by flow restrictions can lead to premature wear and fatigue that can affect pump life and reliability.

Difficulty in maintenance and repair: If the pipe joint is not easily accessible due to its curved or long structure, maintenance and repair tasks become more difficult. Routine inspection, cleaning or replacement of components may require additional effort and time, potentially resulting in extended downtime. To optimize pump performance and mitigate problems associated with bent or long pipe fittings at the suction port, it is imperative to ensure proper installation, alignment and maintenance of the suction piping system. This includes using the proper pipe diameter, minimizing bends and turns, and ensuring tight connections to prevent air leaks. Regular inspection and monitoring of the suction line helps to detect any problems early and facilitates timely corrective action. Seeking guidance from pump manufacturers, industry standards and qualified professionals can provide valuable insight and expertise in designing and maintaining an efficient suction piping system for your specific application.
