The filter is installed at the oil suction port of the oil pump to protect the oil pump and other hydraulic components, avoid the inhalation of pollution impurities, effectively control the pollution of the hydraulic system, and improve the cleanliness of the hydraulic system.
The filter can be directly installed on the side, top or bottom of the oil tank. The oil absorption cylinder invades below the liquid level in the oil tank. The filter head of the filter is exposed outside the oil tank, and is equipped with self sealing valve, bypass valve, filter element pollution blocking transmitter and other devices, so that the oil in the oil tank will not flow out when replacing the filter element and cleaning the filter element Or it is convenient to replace the filter element.
2、 Performance and characteristics
1. Convenient installation and connection, simplified system pipeline:
The filter can be directly installed on the side, top or bottom of the oil tank. The filter head of the filter is exposed outside the oil tank, and the oil absorption cylinder invades below the liquid level in the oil tank. The oil outlet is equipped with pipe and flange connection, and the filter is equipped with self sealing valve and other devices, so that the pipeline can be simplified and installed conveniently.
2. The self sealing valve is set to make it convenient to replace, clean the filter element or maintain the system
When replacing or cleaning the filter element or maintaining the system, just loosen the end cover (cleaning cover) of the filter. At this time, the self sealing valve will automatically close to isolate the oil circuit of the oil tank, so that the oil in the oil tank will not flow out. Therefore, it is very convenient to clean and clean the filter element or maintain the system. If the self sealing valve is opened, it can also be used to drain oil from the oil tank.
3. It has filter element pollution transmitter and oil bypass valve, which improves the reliability of hydraulic system
When the filter element is blocked by pollutants to the oil outlet, and the vacuum degree is 0.018mpa, the transmitter will send a signal, and the filter element should be replaced or cleaned in time. If the unit can not be shut down immediately or there is no one to replace the filter element, the oil way bypass valve on the upper part of the filter element will open automatically (opening value: vacuum 0.02MPa), so as to avoid the oil pump suction failure. But at this time, the filter element should be replaced or cleaned to keep the cleanliness of the hydraulic system and improve the reliability of the hydraulic system.
