Jiangsu Knl High-Pressure Plunger Pump Maintenance and Repair Guide

The high-pressure plunger pump is a crucial core component in hydraulic systems. The high-pressure plunger pumps provided by Jiangsu Knl Hydraulic Pump are widely used in various industrial equipment. To ensure the long-term stable operation and increase the service life of the pump, proper maintenance and care are essential. Below is the maintenance and repair guide for Jiangsu Knl high-pressure plunger pumps:

1. Regularly Check Hydraulic Oil Quality

Hydraulic oil is the power source for high-pressure plunger pumps. Jiangsu Knl Hydraulic Pump recommends regularly checking the cleanliness and viscosity of the hydraulic oil to ensure it meets the standard requirements. It is recommended to replace the hydraulic oil every 6 months, especially when the oil quality becomes dirty or contaminated.

• Oil Quality Check: Test the oil sample for cleanliness, acidity, and other indicators.

• Oil Level Check: Ensure the oil level in the oil tank is within the appropriate range.

2. Clean and Replace Filters

Jiangsu Knl high-pressure plunger pumps are usually equipped with filters to prevent impurities from entering the pump. Regular cleaning or replacing the filters can prevent wear on the pump components.

• Cleaning Frequency: Check the filters every 1,000 hours of operation, and clean or replace them as necessary.

• Replacement Cycle: It is generally recommended to replace the filters once a year, depending on their usage.

3. Inspect and Replace Seals

Seals are essential components for ensuring the normal operation of high-pressure plunger pumps. Jiangsu Knl Hydraulic Pump recommends regularly inspecting the seals (such as O-rings, oil seals, etc.) to prevent leakage and pressure loss.

• Inspection Method: Regularly check if there is any oil leakage around the pump, and inspect if the seals are aging, hardening, or damaged.

• Replacement Cycle: Seals should be inspected every 2 years, and they can be replaced earlier depending on the usage conditions.

4. Inspect the Pump Body and Drive Unit

The pump body and drive unit are important parts of high-pressure plunger pumps. Jiangsu Knl Hydraulic Pump recommends regularly checking the operation of the pump body and drive unit to ensure they are securely connected and prevent pump damage caused by looseness or malfunction.

• Inspection Items: Check the wear on the pump body, the alignment of gears and shafts, and ensure there is no abnormal vibration or noise.

• Drive Unit Check: Regularly inspect the motor, diesel engine, or other drive units to ensure stable power output.

5. Regular Lubrication

Lubrication is crucial for the long-term stable operation of high-pressure plunger pumps. Jiangsu Knl Hydraulic Pump recommends regularly checking the lubrication status of various moving parts inside the pump.

• Lubrication Oil Check: According to the user manual, regularly add special lubrication oil to the moving parts of the pump.

• Lubrication Frequency: Adjust the frequency of lubrication oil addition based on the working environment and pump usage, ensuring proper lubrication.

6. Prevent Overloading and Overheating

High-pressure plunger pumps can experience reduced performance or even damage when operated under high load or high temperature for extended periods. Jiangsu Knl Hydraulic Pump advises users to strictly adhere to the pump’s rated working pressure and flow requirements to avoid prolonged overloading.

• Overload Detection: During operation, monitor the system pressure and temperature, and adjust the working conditions in a timely manner.

• Temperature Control: Ensure the pump operates within the appropriate temperature range to avoid oil degradation or equipment failure due to excessive temperature.

7. Regular Maintenance and Professional Inspection

Regularly invite professional technicians to conduct comprehensive inspections of the Jiangsu Knl high-pressure plunger pump to ensure the proper functioning and performance of the pump. This includes evaluating the wear, corrosion, and operational efficiency of the various pump components.

• Technical Support: Jiangsu Knl Hydraulic Pump provides professional technical support services to help users diagnose and maintain equipment failures.

• Maintenance Records: It is recommended to maintain a record of equipment maintenance and repairs to facilitate tracking and analysis of the equipment’s long-term usage.
