Duplex fuel/lubricating oil filter

Abstract

The invention discloses a duplex fuel / lubricating oil filter, which comprises a body (1). A left filter chamber and a right filter chamber are arranged in the body (1); a plug core seat (5) is arranged between the two filter chambers; a plug core (13) is arranged in the plug core seat (5); a handle (10) connected with the plug core (13) is arranged outside the plug core seat (5), and can control the rotation of the plug core (13); an upper chamber and a lower chamber are arranged in the plug core (13); the upper chamber is communicated with an inlet of a pipeline; the lower chamber is communicated with an outlet of the pipeline; one side of the upper chamber and one side of the lower chamber are sealed, and the other sides of the upper and lower chambers are provided with channels communicated with the filter chambers; a filter cartridge (2) is arranged in the filter chambers; the inlet port of the filter cartridge (2) is communicated with the upper chamber of the plug core (13); and the inflow port of the filter cartridge (2) is communicated with the lower chamber of the plug core (13). The invention provides a duplex fuel / lubricating oil filter, which can ensure that the filter is cleaned or replaced under the condition of no halt.

Description

technical field [0001] The invention relates to a duplex fuel lubricating oil filter. Background technique [0002] Due to the continuous extension of the ship's route, the endurance of the ship must become larger and larger, and it is bound to require the ship to be able to store enough fuel oil and lubricating oil. After the demand for fuel oil and lubricating oil increases, shipowners control costs and suppliers in order to obtain greater Economic interests greatly compromise the quality of fuel and lubricating oil, inevitably increasing the impurity content therein, forcing the addition of filters on the oil path. After the filter works for a long time, it will be easy to cause blockage with the continuous increase of impurities. In this case, the lack of oil supply will affect the normal operation of the machine. It is necessary to clean the filter without stopping the machine. Or replacement, if a set of filters are connected in parallel in the pipeline system, this r...

Problems solved by technology

After the filter works for a long time, it will be easy to cause blockage with the continuous increase of impurities. In this case, the lack of oil supply will affect the normal operation of the machine. It is necessary to clean the filter without stopping the machine. Or replacement, if a set of filters are connected in parallel in the pipeline system, this requirement can also be achieved, but it will increase the cost of shipbuilding and temporarily use the limited space on the ship, which is not worth advocating, so a device is needed to meet these requirements
