The NJU series external and internal accumulation oil suction filter has the advantages of easy connection, easy cleaning or replacement of filter element, easy to achieve oil tank sealing, and is equipped with combination flange, bypass valve, pollution accumulation cup, blockage transmitter and other devices.

1. Easy installation and connection: This filter can be installed on the top or side of the fuel tank cover, with the filter head exposed outside the tank. The suction pipe is inserted into the oil surface from the side of the tank, and the oil outlet is connected to the pump suction port. The 25-160L/min specification is equipped with a combination movable flange, and the connection height can be adjusted up and down Thus achieving full closure of the fuel tank and further preventing pollutants from entering the tank.

2. Convenient cleaning or replacement of filter element: When the filter element needs to be cleaned or replaced, the filter cover can be easily opened, the filter element can be removed and cleaned and replaced together with the dirt cup. After cleaning and replacement, it can be put back in Once the cover is installed, it can be put into use.

3. Equipped with a bypass valve: When the filter element is blocked by pollutants and the vacuum degree at the oil outlet is 0.018MPa, the transmitter will send a signal, and the filter element should be replaced and cleaned in a timely manner. If the machine cannot be stopped immediately or no one comes to replace the filter element at this time, the oil circuit bypass valve located on the upper part of the filter element will automatically open (opening pressure: vacuum 0.02MPa) to avoid oil pump suction and other faults.

4. Filter clogging transmitter: This transmitter is installed on the head cover of the storage filter. When the filter gradually clogs, the outlet vacuum degree and pollution situation of the filter can be observed from the visual mirror surface of the transmitter, and it can also be connected to an electric transmitter.

5. Equipped with a pollution accumulation cup: The working medium flows through the filter chamber to trap pollutants that exceed the filtering accuracy of the filter in the filter chamber, and concentrate them in the pollution accumulation cup. When it is necessary to clean and replace the filter element. The accumulation cup is carried out together with the filter element The filtered pollutants will not cause the pollutants to fall back into the fuel tank when replacing the filter element.

Diameter: 15~90um
