What filter is used in hydraulic systems? Filters are the most common devices in hydraulic systems and can be located in the reservoir, return line, or pressure line. Filters can also be classified according to how much flow they can handle: proportional, full-flow, or kidney-loop. Partially-flushed filters only allow a portion of the fluid to pass through them.
Spin-on filters
Spin-on filters are a type of filter designed to protect individual hydraulic pumps or valves within a hydraulic system. These filters can be installed in line with a bypass valve or without it, and they also have clogging indicators that display the percentage of clogging. Spin-on filters are available in various sizes, including high-pressure, low-pressure, and return and suction types. The filters capture contaminants and block impurities as they flow through the system. This kind of filter is readily available to some hydraulic filter suppliers VA. They can help you determine which hydraulic filter best fits your needs.
The return-line hydraulic filter is a spin-on filter installed on the low-pressure side of the hydraulic system. The use of clean hydraulic fluid extends the life of system components. Spin-on filters are used in industrial, power transmission, and general processing applications. They can handle up to 500 psi in high-pressure environments.
High-pressure filters
Hydraulic systems are used to move heavy equipment. They may also contain hydraulic fluids for power steering and transmissions. In the automotive industry, hydraulic fluids are used in power steering systems, communications, garbage trucks, and aircraft flight control systems. They can even be used in lifts. To ensure the cleanliness of hydraulic fluids, high-pressure filters are an essential part of the system. However, high-pressure filters do more than keep hydraulic systems clean.
High-pressure filters in hydraulic systems are designed to withstand the system’s maximum pressure. They are sized according to the flow rate, which allows them to withstand high working pressures while offering excellent protection to downstream components. These filters are available in various flow rates ranging from low to high. They include threaded, flanged, and various filter components. Some models also have a duplex setup for continuous filtering.
Return line filters
The return line filter is an essential piece of equipment for hydraulic systems. It filters hydraulic fluid before it flows back into the system. This filter comprises several elements that work together to optimize its efficiency. The filter’s portable component is the head. When installed on the machine, it acts as a mounting pad. The inlet and outlet points are crucial in filtration; dirty fluid enters through the inlet and leaves via the outlet.
When choosing return line filters, remember that dirt particles vary in size. Therefore, you should select a filter with a large dirt-holding capacity to minimize unclogging time. If the filter is too small, frequent interruptions are likely. Another thing to consider when choosing a return line filter is the size of the filter element.
Kidney-loop filters
Kidney-loop filters in hydraulic systems extend the service life of hydraulic fluids by improving their condition. These filters extend the drain intervals of hydraulic systems and maintain a steady flow. They are more efficient than other methods of filtering and filtration because they are located off the main hydraulic system. Additionally, these filters are easier to maintain since they do not directly filter fluid and are not connected to the hydraulic circuit.
A kidney-loop filter does not expose the fluid to high pressures and is, therefore, highly effective at removing dirt. Unlike other filters, the filter elements hold the dirt in place and do not release it back into the fluid. This filter can be installed in a stationary or mobile system and may be fitted with pneumatic motors for better portability. It is essential to check the system efficiency as it could decrease by 20% before the operator realizes there is a problem. Cylinder drift, jerky steering, and reduced cylinder performance are all symptoms. These symptoms may increase a system’s operational expenses and reduce productivity. Kidney-loop filters can potentially remove the majority of particle pollutants while also prolonging the service life.
