Hydraulic pump operation manual


Thank you for choosing our excavator hydraulic pump products. This operation manual will provide you with detailed instructions and maintenance guides to help you fully understand and correctly operate the excavator hydraulic pump to ensure that it provides powerful power for your excavator efficiently and stably.

Product Overview:
Excavator hydraulic pump is the core component of excavator hydraulic system, which is used to transport hydraulic oil and provide power for hydraulic components. It has the characteristics of high flow output and high pressure stability, and is suitable for various excavator models and application scenarios.

Safety Information:
Before operating the hydraulic pump of the excavator, be sure to carefully read and follow the following safety instructions:

Before operation, ensure that the excavator is in a stable shutdown state and cut off the power source.
It is strictly prohibited to open the cover plate of the hydraulic pump or remove key components during operation.
When maintaining and maintaining hydraulic pumps, relevant safety procedures and operating regulations must be observed.
Operation steps:
Follow these steps to properly operate the excavator hydraulic pump:

Step 1: Ensure that the hydraulic pump and excavator are shut down and cut off the power source.

Step 2: Check the liquid level of the hydraulic pump to ensure that the hydraulic oil is within the appropriate mark line range.

Step 3: Start the power source of the excavator, slowly increase the speed of the hydraulic pump, so that it reaches the normal working state.

Step 4: According to the actual work needs, adjust the output flow and pressure of the hydraulic pump to ensure that it meets the work requirements.

Step 5: During the work of the excavator, pay attention to monitoring the operating status of the hydraulic pump, and stop the machine in time for inspection if there is an anomaly.

In order to ensure the normal operation of the hydraulic pump of the excavator, regular maintenance is very important. Here are some suggestions:

Check the liquid level of the hydraulic pump every day, and add hydraulic oil in time.
Replace the hydraulic oil regularly and clean the tank and filter.
Check the seals and connecting parts of the hydraulic pump to ensure that there is no oil leakage.
Check the operating status and pressure of the hydraulic pump regularly, and deal with any anomalies in time.
During use, if the hydraulic pump is abnormal, you can preliminarily eliminate it according to the following methods:

If the hydraulic pump oil leakage is found, check whether the seal is damaged and replace it in time.
If the hydraulic pump appears noise or vibration, check whether the pump body and connecting parts are loose.
If the output flow of the hydraulic pump is unstable, check whether there is blockage or pump body damage.
If you can not solve the problem, please contact our after-sales service team in time, we will provide you with professional technical support.
