Q: How often does the Doosan hydraulic filter need to be replaced?
There is no fixed replacement cycle for Doosan hydraulic filters, which are generally calculated based on working hours or time. It is recommended to replace them every 500 hours, with a maximum of 6 months or 2000 hours, depending on the type of filter element and operating conditions.
🛠️ Replacement cycle reference
- Hydraulic Return oil filter: Replace it after 250 hours of initial operation and every 500 hours thereafter.
- Suction Strainer Filter : relatively durable, usually replaced every 2000 hours.
- Pilot Oil filter: synchronized with the return oil filter element, replaced approximately every 500 hours.
Time benchmark: Change approximately every 6 months according to calendar time, and shorten to 3-4 months for construction sites with high frequency of use or dust.
⚠️ Factors affecting the cycle
- Poor working conditions: often equipped with a crushing hammer or high dust, the cycle is shortened to 100-300 hours.
- Oil quality: The hydraulic oil is of poor quality and the filter element is prone to clogging, so it needs to be replaced in advance.
- Abnormal signal: The hydraulic system pressure is unstable and there is abnormal noise. Even if it has not reached the cycle, it should be checked and replaced in a timely manner
Q: What types of hydraulic filters are available on Doosan equipment?
In a complete Doosan hydraulic system, there is usually more than one filter, each of which performs its own function:
- Suction Filter: Located inside the hydraulic oil tank, the suction port of the pump is used to block large particles and impurities from entering the pump body.
- Return Line Filter: Located on the pipeline of hydraulic oil returning to the oil tank, it is the main system cleaning filter.
- Pilot Filter: Filter high-precision hydraulic oil in the control circuit to protect sensitive handle control valves.
- Pressure Filter (equipped on some models): Installed downstream of the hydraulic pump, it directly protects the main control valve and core hydraulic motor.
