When environment temperature locating for oil rectifier 100 is lower than preset temperature T, if the opening state duration of by-passing valve 2 is less than
Preset time period t, magnetic sensor 61 do not generate bypass signal.If the opening state duration of by-passing valve 2 is more than pre-
If after time period t, magnetic sensor 61 generates bypass signal.In other words, when environment temperature is lower than preset temperature, even if magnetic
Sensor 61 detects that by-passing valve 2 is opened, and will not generate bypass signal immediately, but can postpone by the regular hour just generates
Messenger.
In other specific embodiments, temperature sensor 65 is directly connected with wireless communication device 64, in oil strainer
When environment temperature locating for clear device 100 is lower than preset temperature T, preset if the opening state duration of by-passing valve 2 is less than
Time period t, and when subsequent recovery to closed state again, wireless communication device 64 does not send bypass signal.It is located in by-passing valve 2
After opening state continues preset time period t, wireless communication device 64 just externally transmits wirelessly bypass signal.In other words, in environment
When temperature is lower than preset temperature, even if magnetic sensor 61 generates bypass signal, wireless communication device 64 will not be sent immediately
Bypass signal, but can postpone certain time and just send bypass signal.
Preset time period t can be arranged according to specific environment, as long as after engine runs the preset time period, machine oil temperature
Degree improves, and viscosity is decreased without influence machine oil and moves smoothly through filter core 3.
