Storage Requirements and Precautions for Hydraulic Pumps

1. Environmental Conditions

The storage area for Komatsu excavator spare parts is subject to specific regulations, primarily concerning moisture and water protection, followed by prevention of contact with acidic gases and liquids. During storage, the hydraulic pump should be placed in a dry, well-ventilated, odor-free, and shaded indoor environment to avoid direct exposure to sunlight or rain. Additionally, it is essential to prevent contact with corrosive gases to avoid damage to the pump body.

2. Temperature Conditions

The pump should be maintained at a specific temperature range, typically between 0°C and 35°C. It is important to keep the indoor temperature stable during storage to avoid significant fluctuations.

3. Humidity Conditions

During storage, the pump should be protected from excessively high or low humidity levels to prevent damage to the pump body and electrical components. The relative humidity in the storage environment should be kept below 60% to avoid moisture accumulation.

4. Shock Protection

The pump must be protected from vibrations or shocks during storage. This is especially crucial for high-precision, high-speed, and high-pressure pumps, as even slight vibrations can adversely affect performance.

5. Preparation Work

Cleaning: Before storage, all mechanical equipment should be thoroughly cleaned. Empty any liquids from the pump and clean it with a suitable detergent to prevent residue from affecting future use.

Lubrication: Before sealing, inject an appropriate amount of lubricant into the pump to prevent rust and damage to internal parts.

Sealing: Seal the pump’s inlet and outlet with plugs to prevent dust, moisture, and other contaminants from entering the pump, which could affect its next use. It is important to conduct periodic maintenance on hydraulic pumps that are not used for extended periods to ensure the proper functioning of internal components. For long-term storage, it is advisable to empty the pump of liquids and place it in a dry, well-ventilated location to prevent moisture and corrosion.

Hydraulic pumps convert hydraulic energy into mechanical energy and are widely used in various fields, including industrial, agricultural, and aerospace applications. Common types of hydraulic pumps include piston pumps, gear pumps, and screw pumps. When using hydraulic pumps, it is essential to monitor parameters such as working pressure, flow rate, and power to ensure proper operation. Prolonged operation of hydraulic pumps can generate high temperatures and wear, necessitating regular maintenance and parts replacement.

6. Placement Conditions

Position the pump on a stable, flat surface, with wooden blocks placed under the tracks to minimize exposure to dampness, salt, and dust. The piston rod should be retracted, and the cylinder should be in a relaxed state. It is advisable to operate and move the machine short distances each month to ensure a fresh layer of oil forms on the moving parts.

7. Maintenance Conditions

Regular maintenance and inspections should be conducted during storage, including checking for looseness or wear, and removing dust and dirt to prevent damage to internal components. Additionally, anti-rust treatments should be applied to extend the pump’s lifespan.

By understanding the storage conditions for hydraulic pumps, users can enhance their lifespan and efficiency. Therefore, it is crucial for users to familiarize themselves with relevant knowledge about pumps to ensure the normal operation of the equipment.
