Common failures and repair methods of BAOLILAI 83056302 hydraulic pump
As the core component of the hydraulic system, the operating status of the hydraulic pump directly affects the working efficiency and safety of the entire mechanical equipment. Although BAOLILAI hydraulic pumps are widely used in many fields such as engineering machinery, industrial equipment and agricultural machinery due to their high performance and high reliability, they may still fail during long-term operation due to the use environment, improper maintenance or natural wear. This article will systematically analyze the common failure phenomena and repair methods of BAOLILAI MPV-046-C-B-B-B-S-B-B-AA-B-A-BFF-CD-A-HH-F-NNN-*** hydraulic pumps to help users effectively troubleshoot problems and extend the service life of equipment.

1. Analysis of common failure types and causes 1. Hydraulic pumps have loud noises and obvious vibrations. Possible reasons:
   Hydraulic oil contains air or impurities, causing cavitation;
   Poor sealing of the suction pipe or clogged oil filter;
   Insufficient installation or excessive coaxiality error of the coupling.
   Solution:
   Check whether the oil has deteriorated, exhaust and drain, and replace clean hydraulic oil;
   Check the sealing of the oil suction line, clean or replace the oil filter;
   Adjust the coupling installation to ensure that the coaxiality error is within the allowable range.
2. Possible reasons for insufficient flow and low output pressure of the hydraulic pump:
   Insufficient oil suction or too low oil tank level;
   Internal seal wear, resulting in serious leakage;
   Speed ​​is too low or variable mechanism fails.
   Solution:
   Check the oil tank level to ensure that the oil suction pipe is unobstructed;
   Replace the seal and repair the worn parts;
   Check the motor speed and test whether the response of the variable control system is normal.
3. Possible reasons for overheating of the hydraulic pump and abnormal temperature rise:
   Long-term overload operation;
   Poor oil circulation and cooling system failure;
   System pressure is set too high or the pressure relief valve fails.
   Solution:
   Reduce the workload and run intermittently appropriately;
   Check whether the cooler is blocked and whether the fan is running normally;
   Adjust the system pressure and repair or replace the faulty safety valve or overflow valve.
4. Possible causes of oil leakage:
   Aging or damage of sealing rings and oil seals;
   Loose fasteners and poor sealing of pump body joint surfaces;
   Improper selection of hydraulic oil, resulting in corrosion of sealing materials.
   Solutions:
   Replace original seals and regularly check aging conditions;
   Check pump body bolts and re-tighten, apply glue seals when necessary;
   Select hydraulic oil with recommended viscosity and compatible materials.
   II. Preventive measures and maintenance recommendations Regular oil change and filter cleaning It is recommended to check the oil quality every 1000 hours of operation and replace the hydraulic oil every 2000 hours. The oil filter needs to be cleaned or replaced simultaneously to keep the system clean.
   Establish a spot inspection system to inspect key parameters such as operating sound, temperature, and pressure at fixed points every week, record the trend of changes, and identify potential faults in advance.
   Standardize the operating procedures and strictly follow the start-up, loading, unloading and shutdown sequence to avoid frequent start-up and power-off restarts causing hydraulic shock.
   Maintain a suitable working environment to prevent dust, water vapor, high temperature and other factors from affecting the operation of the pump body. It is recommended to add a protective cover or ventilation device in places with harsh environments.
   Regular training of maintenance personnel to improve operation and maintenance skills, ensure that common faults can be accurately judged and handled in the first time, and reduce downtime and maintenance costs.
5. Service support and spare parts guarantee BAOLILAI provides a full range of original hydraulic pump accessories, including pistons, cylinders, shaft seals, distribution plates and other key components, to ensure that customers can complete repairs in the shortest time.
