Embodiment

In order to solve diesel generating set oil filtration system control mode single, easily cause changing filter problem not in time, now provide a kind of can pressure reduction report to the police and the generator set that automatically switches for oil filtration system.

Below in conjunction with the accompanying drawing in the utility model, be clearly and completely described the technological scheme in the utility model, obviously, that described is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to the scope of the utility model protection.

As Figure 1-3, a kind of can pressure reduction report to the police and the generator set that automatically switches for oil filtration system, comprise generator set 15 and oil pump 14, be connected with for oil filtration system 16 between the machine oil import of described generator set 15 and described oil pump 14, described as follows for oil filtration system 16 structure:

Machine oil input end 12 points has three branch roads, connects the first stop valve 1, second stop valve 2, the 3rd stop valve 3 respectively, and described first stop valve 1 output terminal is connected with the first solenoid valve DT1, the first oil strainer 4, the 4th stop valve 5, first one-way valve 6 in turn,

Described second stop valve 2 output terminal is connected with the second solenoid valve DT2, the second oil strainer 7, the 5th stop valve 8, second one-way valve 9 in turn, and described first one-way valve 6 converges with the output terminal of described list two way valve 9 and is connected machine oil output terminal 13,

Described 3rd stop valve 3 output terminal is connected with two branch roads, connect the 6th stop valve 10, the 7th stop valve 11 respectively, the output terminal of described 6th stop valve 10 is connected between described first stop valve 1 and described first oil strainer 4, the output terminal of described 7th stop valve 11 is connected between described second stop valve 2 and described second oil strainer 7

The two ends of described first oil strainer 4 are parallel with the first pressure reduction relay 1P, the two ends of described second oil strainer 7 are parallel with the second pressure reduction relay 2P, the function that described first pressure reduction relay 1P and the second pressure reduction relay 2P is equipped with the pre-alarm of the pressure reduction low upper limit, the low lower limit of pressure reduction starts stand-by provision, this control principle drawing is shown in Fig. 3.

Design of the present utility model makes it obtain two kinds of control loops, and one is Non-follow control loop, You Liangzhong path, Non-follow control loop:

1, machine oil enters from machine oil input end 12, and approach the 3rd stop valve 3, the 6th stop valve 10, first oil strainer 4, the 4th stop valve 5, first one-way valve 6, then flow out from machine oil output terminal 13;

2, machine oil enters from machine oil input end 12, and approach the 3rd stop valve 3, the 7th stop valve 11, second filter 7, the 5th stop valve 8, second one-way valve 9, then flow out from machine oil output terminal 13;

When machine oil is only through path 1, if the first oil strainer 4 blocks because of long-term work, the low upper limit pre-alarming device of pressure reduction on first pressure reduction relay 1P will give the alarm, now can the first oil strainer 4 in path 1 be changed, machine oil switches to path 2 and filters, when machine oil is only through path 2, processing method is the same;

And another kind is automatic control loop, automatic control loop has two kinds of paths equally:

A. machine oil enters from machine oil input end 12, and approach first stop valve 1, first solenoid valve DT1, the first oil strainer 4, the 4th stop valve 5, first one-way valve 6, then flow out from machine oil output terminal 13;

B. machine oil enters from machine oil input end 12, and approach second stop valve 2, second solenoid valve DT2, the second oil strainer 7, the 5th stop valve 8, second one-way valve 9, then flow out from machine oil output terminal 13;

When machine oil is only through path A, if the first oil strainer 4 blocks because of long-term work, pressure reduction on first pressure reduction relay 1P reaches low and above then can report to the police in limited time, now can the first oil strainer 4 in path 1 be changed, if pressure reduction has reached low lower limit, then the first pressure reduction relay 1P has controlled the first solenoid valve DT1, and machine oil switches to path B and filters, when machine oil is only through path B, processing method is the same;

Certainly, except above-mentioned first oil strainer 4, second oil strainer 9 works independently, the first oil strainer 4, second oil strainer 9 can also be made to work, to increase work efficiency simultaneously.

By above-mentioned known, the utility model has the advantage of: by being provided with pressure reduction relay, solenoid valve and stop valve, Non-follow control can be realized and automatically control switch filtering system, pressure reduction relay is provided with pressure reduction low upper limit pre-alarm function, can need to remind staff to change filter rinsed in time during cleaning at filter, also be provided with the low lower limit of pressure reduction and start stand-by provision function, can switch filtering system in time, guarantee filtration work is uninterrupted.Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
