Abstract
The utility model relates to a kind of emergency fire pump self-suction system peculiar to vessel with air extractor, be characterised in that: comprise emergency fire pump, with the pipeline of emergency fire pump inlet communication, vacuum pump and gas-liquid splitter cylinder, pipeline between emergency fire pump and vacuum pump is provided with liquid-level switch, filter, one-way valve and solenoid valve successively, the described pipeline the other end connects vacuum pump and vaccum pump motor, described vacuum pump outlet connects gas-liquid separation cylinder, is provided with pressure relay in the outlet of emergency fire pump.Advantage is: utilize marine electric machine to drive Nash hytor to bleed to emergency fire pump and pipeline, without the need to external gas source, safe and reliable, saves space, not by the restriction of applying working condition, improves pumping efficiency.
Description
Technical field
The utility model belongs to ship's fire fighting pump technical field, particularly relates to a kind of emergency fire pump self-suction system peculiar to vessel with air extractor.
Background technique
In order to security against fire builds specification according to Classification of Vessel, boats and ships must arrange emergency fire pump for playing the effect of fire-fighting fire extinguishing under the main fire water pump failure conditions in cabin beyond engine space.Before emergency fire pump starts, need by self-suction system, the air in pipeline all to be aspirated totally.Traditional air extractor is generally divided into pneumatic air extractor or mechanical air extractor, and aforementioned pneumatic air extractor needs external gas source, due to cabin limited space and consider the Security of external gas source, therefore pneumatic air extractor is subject to the restriction of applying working condition; Aforesaid mechanical air extractor, because friction wheel easily occurs the phenomenon that throws switch, causes the speed of exhaust slow, inefficiency.
Summary of the invention
The utility model for solve in known technology the technical problem that exists and provide a kind of structure simple, can the narrow applying working condition of meeting spatial, improve pumping efficiency and possess the emergency fire pump self-suction system peculiar to vessel with air extractor of safety reliability.
The technological scheme that the utility model is taked for the technical problem existed in solution known technology is:
There is the emergency fire pump self-suction system peculiar to vessel of air extractor, it is characterized in that: comprise emergency fire pump, with the pipeline of emergency fire pump inlet communication, vacuum pump and gas-liquid splitter cylinder, pipeline between emergency fire pump and vacuum pump is provided with liquid-level switch, filter, one-way valve and solenoid valve successively, the described pipeline the other end connects vacuum pump and vaccum pump motor, described vacuum pump outlet connects gas-liquid separation cylinder, is provided with pressure relay in the outlet of emergency fire pump.
The utility model can also adopt following technological scheme:
Described vacuum pump adopts Nash hytor.
Described liquid-level switch, solenoid valve, pressure relay and vaccum pump motor all adopt liquid-level switch, solenoid valve, pressure relay and the vaccum pump motor with explosion-proof and insulation function.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme, Nash hytor is driven to bleed to fire water pump and pipeline by utilizing marine electric machine, when liquid reaches liquid-level switch precalculated position, liquid-level switch sends signal enabling fire water pump, when fire water pump outlet pressure is to pressure relay setting pressure, pressure relay sends signal at stop Nash hytor, and Nash hytor stops vacuumizing.If during fire water pump work, outlet pressure reduces, and pressure relay can send signal again, start Nash hytor, fire water pump and pipeline are bled.This self-suction system achieves Electronic control air extractor, and self-priming is reliable, efficiency is high, flow is large, effectively can prevent the dry running of fire water pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, emergency fire pump; 2, vaccum pump motor; 3, Nash hytor; 4, gas-liquid separation cylinder; 5, solenoid valve; 6, one-way valve; 7, filter; 8, liquid-level switch; 9 pressure relayes; 10, pipeline.
Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, there is the emergency fire pump self-suction system peculiar to vessel of air extractor, comprise emergent fire-fighting 1 pump, with the pipeline 10 of emergency fire pump inlet communication, vacuum pump and gas-liquid splitter cylinder 4.Pipeline 10 between emergency fire pump and vacuum pump is provided with successively liquid-level switch 8, filter 7, one-way valve 6 and solenoid valve 5, the described pipeline the other end connects vacuum pump and vaccum pump motor 2, described vacuum pump outlet connects gas-liquid separation cylinder 4, is provided with pressure relay 9 in the outlet of emergency fire pump.
Described vacuum pump adopts Nash hytor 3.
Described liquid-level switch, solenoid valve, pressure relay and vaccum pump motor all adopt liquid-level switch, solenoid valve, pressure relay and the vaccum pump motor with explosion-proof and insulation function.
Detect liquid level height by liquid-level switch, when liquid level reaches predetermined altitude, emergency fire pump peculiar to vessel is started working, and after emergency fire pump work peculiar to vessel, outlet pressure increases, and when reaching pressure relay predetermined pressure, Nash hytor cuts out, and can stop vacuumizing.
Because this self-suction system utilizes marine electric machine to drive Nash hytor to bleed to fire water pump and pipeline, without the need to external gas source, safe and reliable, save space, not by the restriction of applying working condition; Also pumping efficiency can be improve simultaneously.
The embodiment that the utility model accompanying drawing describes is exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
