Description

Fuel system stable-pressure device
Technical field
The utility model relates to fuel system equipment technical field.
Background technology
Nowadays, the development of the fuel system of China is more and more perfect, with it efficient, power bracket is broad, has been widely used in industry, agricultural, the field such as dual-use.Within considerable time from now on, fuel system also will occupy epochmaking status.Along with being on the increase of fuel system quantity, also result in the concern of people to its some shortcomings aspect.Traditional fuel system is all a fuel pump and a return wire, and two heating furnaces there will be the phenomenon of the amount of striving, and system pressure is fluctuated, causes furnace temp unstable, the comprehensive quality that impact is produced, even causes catastrophic failure and accident; In addition, the filter of fuel system fuel feeding end often needs cleaning, needs the short time to close oil supply system, drops into after clearing up to filter screen again, although the time is very short, and the normal operation of ability recovery system after also needing a few minutes.Fuel can be caused like this to feed back abnormal increase, and the instruction of fuel system is constant, so just requires that fuel command reduces rapidly, the comprehensive quality that impact is produced and efficiency.
Utility model content
Technical problem to be solved in the utility model, it is the technical deficiency for above-mentioned existence, a kind of fuel system stable-pressure device is provided, a fuel pump controls a heating furnace, separately the use amount of fuel oil is not involved, other fuel pressure can not be affected, heating furnace is better controlled, product quality is more stable, improves the comprehensive quality of product.
The technical solution adopted in the utility model is: provide a kind of fuel system stable-pressure device, and it includes fuel oil drum, fuel oil extracts line, two heating furnaces out; Line main line extracted out by fuel oil and fuel oil drum is connected, and the branch road that line extracted out by fuel oil is connected with each heating furnace respectively; The top that line branch road extracted out by every bar fuel oil is all provided with fuel pump, and stage casing is connected with fuel oil return wire respectively, and every bar fuel oil return wire is all connected with fuel oil drum; The end extracting line branch road at every bar fuel oil out has connected stokehold return wire respectively, and every bar stokehold return wire is connected with fuel oil return wire respectively; Each stokehold return wire is equipped with A pressure-control valve; The branch road that line extracted out by each fuel oil is equipped with B pressure-control valve.
Further optimization the technical program, fuel system stable-pressure device is extracted out on line main line at fuel oil and has been installed in parallel two filters, and each filter two ends are all provided with the segment switch of interlock.
Further optimization the technical program, fuel system stable-pressure device is at the rear portion at stokehold return wire, and the branch road end that line extracted out by each fuel oil is all provided with flowmeter counter.
Utility model is compared with traditional fuel system, its beneficial effect is: 1, fuel oil is extracted line out and is divided into two, every bar fuel oil extract out line Lu Shangjun fuel pump is installed, like this, a fuel pump controls a heating furnace, separately the use amount of fuel oil is not involved, cut off the contact between heating furnace, other fuel pressure can not be affected, avoid mutually restricting between heating furnace, heating furnace is better controlled, and product quality is more stable, improves the comprehensive quality of product.2, fuel oil extraction line main line is divided into two, the two alternation, and every bar main line is all provided with filter, and each filter two ends are all provided with segment switch; After a fuel oil extraction line main line works a period of time, filter reaches the condition needing cleaning, another fuel oil can be enabled and extract line main line out, clear up current fuel oil and extract line main line out, this avoid closedown oil supply system, fuel can not be caused to feed back abnormal increase, improve comprehensive quality and the efficiency of production.3, the downstream that every bar fuel oil extracts line branch road and stokehold return wire cut-in point out is separately installed with flowmeter counter, that can monitor fuel so in real time enters furnace volume, thus understand the operating efficiency of heating furnace, and whether working alone of two heating furnaces can be known.
