Q: What is the function of a suction filter?
The function of the suction oil filter is to be installed at the oil pump's suction port, filtering out solid particles, metal shavings, and other impurities from the hydraulic oil.
1. Core Fundamental Functions
- Coarse filter guard: Intercepts large residual particles in the oil tank to prevent the oil pump from drawing in contaminants, which could cause wear, jamming, or cavitation in the pump.
- Pollution Control: By managing oil cleanliness from the oil suction end, it reduces wear on subsequent precision components such as hydraulic valves and cylinders, extending the service life of hydraulic oil by approximately 400 hours.
- Flow Assurance: Utilizing a low-resistance 100-200 mesh metal woven screen structure, it ensures filtration effectiveness while minimizing excessive resistance to oil pump suction.
2. Additional Special Features
- Self-sealing protection: Some models equipped with a self-sealing valve can automatically close the oil passage when replacing the filter element, preventing oil leakage from the tank and blocking contaminants from flowing back into the tank during shutdown.
- Redundant Protection: A built-in bypass valve automatically opens when the differential pressure reaches 0.3~0.7MPa due to filter element clogging, preventing system oil starvation and shutdown.
- Working Condition Adaptation: Some patented models with cleaning structures can automatically remove impurities adhering to the outer wall of the filter element, reducing the frequency of manual cleaning.
3. Differentiated Functions of Various Types of Oil Suction Filters
- Oil suction filter screen: Suitable for hydraulic oil tanks in construction machinery, it can be repeatedly cleaned and reused without frequent replacement.
- Oil Absorption Filter Bag: Specifically designed to remove trace amounts of oil from liquids, capable of adsorbing 15 to 23 times its own weight in grease while intercepting particles ranging from 1 to 100 microns, suitable for applications in electrophoretic coating and wastewater treatment.
- Self-sealing oil suction filter: During shutdown, the spring automatically compresses the filter element to form a sealing barrier, reducing the likelihood of early wear in equipment by over 75%.
Q: What happens if you don't use a strainer filter?
If the oil suction filter is not used, it will directly damage the oil cleanliness barrier of the hydraulic system, causing a series of chain failures from core component damage to complete machine paralysis, seriously affecting the safety and service life of equipment operation.
1、 Direct damage to core power components
- Oil pump failure: unfiltered oil entering the oil pump directly can cause abnormal increase in oil suction resistance, resulting in insufficient oil suction, cavitation, abnormal noise and heat generation, ultimately leading to the burning of the oil pump.
- Sudden decline in oil pump lifespan: Iron filings and hard particles in the oil can directly scratch the precision mating surfaces inside the oil pump. An oil pump that could have run for thousands of hours may experience severe wear and even be scrapped in a short period of time.
2、 Downstream hydraulic system interlock failure
- Abnormal component operation: Impurities entering the high-pressure circuit can cause downstream oil cylinders and hydraulic valves to move slowly, or even become stuck or completely inactive, directly interrupting the equipment operation process.
- System pollution diffusion: Impurities intercepted by non oil absorbing filters will circulate throughout the hydraulic system, continuously contaminating all hydraulic components and causing a series of secondary failures such as valve core jamming and seal wear.
3、 Additional hazards of long-term operation
- Maintenance costs skyrocket: After losing the protection of the oil suction filter, the cleanliness of the hydraulic oil deteriorates rapidly, the oil change cycle is greatly shortened, and various hydraulic components need to be frequently inspected and replaced, resulting in tens of thousands of yuan in maintenance costs and high downtime losses.
- Job safety hazards: Sudden hydraulic failure of heavy-duty equipment such as railway maintenance and construction machinery may cause safety risks such as interruption of line maintenance and engineering accidents, affecting on-site work efficiency and personnel safety.
