Common Issues with Linde Hydraulic Pumps

Linde hydraulic pumps are generally known for their quality and efficiency, but like any other mechanical devices, they can encounter issues. Note that some of these issues could be specific to the model or the operating conditions. Here are some common issues that might arise with Linde hydraulic pumps:

1. Loss of Pressure: Over time, seals and gaskets may wear out, leading to reduced pressure. Loss of pressure will affect the hydraulic system’s performance.
2. Excessive Noise: Unusual noise could signify cavitation, air entrapment, or other internal issues.
3. Overheating: This can be due to excessive load, inadequate cooling, or low fluid levels. Overheating can damage other components and reduce efficiency.
4. Leakage: Seals or gaskets can fail, causing hydraulic fluid to leak. Leakage is not only wasteful but can also be a safety hazard.
5. Cavitation: This occurs when the pump draws in air instead of fluid, leading to the formation of bubbles, which can cause damage when they collapse.
6. Erratic Operation: This could be due to electrical issues, or problems in the control valves, leading to inconsistent movement and operation.
7. Slow Response: Sluggish operation can occur due to worn-out parts, poor fluid quality, or blockages in the hydraulic lines.
8. Contaminated Fluid: The presence of dirt, water, or other contaminants can severely impact pump performance and may cause premature wear and tear.
9. Unintended Motion: This could be due to issues in the control systems or feedback loops, leading to inaccurate or unintended movement.
10. Wear and Tear: Normal wear and tear will eventually reduce the efficiency and reliability of any hydraulic pump. Regular maintenance can mitigate this but can’t eliminate it entirely.

Reassembly

The oil level in the reservoir should always be at least 8 inches (~200mm) above the highest point of the pump as illustrated below:

Installation:

• Always cover or cap all HPV-02 case drain, control, and high pressure hydraulic lines during the installation of a new or replacement HPV-02 pump.
• Always ensure all connections to the HPV-02 replacement pump are capped or covered during initial installation.
• Connect and tighten each hydraulic line one at a time removing caps or covers just before each connection is made.
• Installation must be carried out in accordance with the circuit or piping diagram.
• It is recommended that the HPV-02 pumps be mounted with the pump control facing upward (as illustrated above).
• The pump can optionally be mounted with the pump control facing to either side. During start-up, additonal care must be taken to vent entrapped air from the pump control via the highest flow stop adjustment (see the sketch above).
• Avoid mounting the pump with the pump control facing down. Entrapped air is difficult to remove and any contaminants in the hydraulic oil will eventually settle into the control.

Venting:

• Positive venting is vital for the proper operation of the hydraulic system.
• The highest case drain port on the pump housing must be connected to the reservoir. If the pump control is mounted on top (as illustrated above), then the vent port in the pump control should be connected to the reservoir as well.
• All vent lines must be mounted continuously rising toward the reservoir. This allows any entrapped air to escape freely from the pump case.

Piping:

• Pipe work should be seamless drawn precision steel tube or hoses of suitable pressure rating.
• During installation, attention should be paid to cleanliness. The pipes must be deburred, washed and blown through.
• Scaled or rusted pipes must be scoured and then neutralized – Hoses must be brushed and flushed through when contaminated.

Filling the Hydrostatic Transmission:

• The initial filling of the system must be carried out in such a way that all of the air can escape from the high pressure circuit and from the pump/motor cases before the hydraulic units are operated.
• The integral purge valve, which may be fitted as an option on the Linde hydraulic motors, assists in the venting of air from the high pressure circuit. This optional purge valve is illustrated in the schematic below. With a pressure differential of about 350 psi (25 bar) across the hydraulic motor, the
  purge valve discharges a controlled amount of oil flow out of the high pressure circuit into the motor case. Therefore, any entrained air may escape freely to the reservoir.Again, refer to the schematic below.

• The hydraulic motor(s) must be free to rotate under no load. For example, when a vehicle is chocked up with the wheels/tracks clear of the ground and free to rotate.

• If already fitted, loosen the vent plugs on the cooler.
• Manually fill the HPV-02 pump case at the most accessible case drain port with filtered oil. Manually fill the high-pressure (closed loop) lines with filterd oil if the lines are extremely long. Fill the oil reservoir to the maxmium level with filtered oil, and fill the motor case(s) to the maximum level via the most accessible case drain port with filtered oil.
• Connect bleed lines or hoses to high pressure gauge ports “Mp” and “Ms”. Connect a 1000 psi (70 bar) pressure gauge or transducer to gauge port “X”.

Disconnect the prime mover’s starting mechanism to insure that the prime mover will
NOT start.

• “Crank” the prime mover for at least ten seconds and stop while simultaneously monitoring the charge pressure at port “X”. Continue this procedure at least 5 times or until the charge pressure at port “X” increases to the integrated boost relief valve setting in the pump (Consult Linde if unsure what boost relief valve setting is in the pump – The pump serial number is mandatory for this request). During this step, air in the closed loop should be discharged from the bleed lines. All air must be removed from the closed loop lines.
• Check the hydraulic oil level in the reservoir and HPV-02 case. Add filtered oil to each as required.
• Reconnect the prime mover’s starting mechanism.
• Start the prime mover and leave at low idle. Operate the prime mover at low idle for about 10 minutes while monitoring the charge pressure at port “X”. The charge pressure at port “X” should remain at the boost relief valve setting.
• Turn the prime mover OFF. Disconnect the bleed lines from gauge ports “Mp” and “Ms” and securely recap the ports.

Testing and Quality Control

Begin by emphasizing the importance of thorough testing and quality control as the final step in the repair or maintenance process of a Linde hydraulic pump. Explain how these checks validate the efficiency and safety of the system, ensuring that it meets operational and quality standards.

Running Initial Tests

1. Preparation: Confirm that the hydraulic pump and system are reassembled correctly, and all connections are secure. Make sure to follow safety protocols.
2. Visual Inspection: Prior to initiating tests, perform a quick visual inspection to double-check the assembly and look for any potential issues like loose bolts, misalignments, or missing components.
3. Initial Power-Up: Turn the pump on for a brief period without fully engaging it, monitoring for immediate issues like strange sounds or visible leaks.
4. Functional Checks: Conduct a set of functional tests to verify actions like valve operation, pressure build-up, and fluid flow. Confirm that all control mechanisms are working as intended.
5. Consult Manufacturer’s Guidelines: Refer to the manufacturer’s guidelines for specific operational tests tailored to the particular model of your Linde hydraulic pump.

Checking for Leaks and Noises

1. Pressure Test: Conduct a high-pressure test to check the integrity of seals, hoses, and connections. Use a pressure gauge to ensure that the system holds pressure within the manufacturer’s specified range.
2. Leak Detection:
   • Visual Inspection: Look around joints, seals, and other potential leak points for any signs of hydraulic fluid.
   • Leak Detection Fluid: Some technicians use special leak detection fluids or dyes to identify hard-to-spot leaks.
3. Auditory Checks:
   • Listen: Operate the pump and listen for abnormal sounds like grinding, squeaking, or high-pitched whines.
   • Use Diagnostic Tools: Some advanced setups use acoustic or vibration sensors to detect unusual sounds that might not be audible to the human ear.
4. Vibration Analysis: Use specialized tools to measure vibrations in the system. Abnormal vibration patterns can be indicative of misalignments, wear, or internal issues.
5. Thermal Imaging: In advanced setups, thermal imaging cameras can be used to identify hot spots that may indicate excessive friction, misalignment, or other issues.
6. Documentation: Record all test results, both successful and unsuccessful, for future reference and quality control.

Conclude the section by stating that rigorous testing and quality control are essential in ensuring that a Linde hydraulic pump performs safely and efficiently. Mention that regular testing should be integrated into the maintenance routine to continually monitor the system’s health and functionality.

Feel free to add, remove, or modify any steps based on the specific model and operating conditions of your Linde hydraulic pump.
