Description
Technical field
The utility model relates to a kind of heat test and concentrates feed system with fuel oil.
Background technology
For making automobile, motor, engine such as peculiar to vessel; before dispatching from the factory, all must carry out heat test; traditional engine thermal test fuel delivery mode is on each stand side a fuel tank that has fuel pump to be set, and to engine oil, the oil return of engine also flows in this fuel tank; when output increases; stand fuel tank quantity increases thereupon, and the security crisis in pilot region just increases, and ignites in case leak; a fuel tank is exactly a cookle, and its consequence is hardly imaginable.
Summary of the invention
The safety problem that the utility model brings at the irrationality of traditional hot test fuel oil supply system layout, provide a kind of desirable heat test to concentrate feed system with fuel oil, this system is away from the heat test zone, can be simultaneously to a plurality of test-bed fuel feeding, efficiently solve safety problem, and help enterprise's increase output.
The technical solution of the utility model is as follows:
This heat test fuel oil concentrates feed system to be divided into fuel delivery subsystem and the lineal system of oil return, two parts all respectively parallel by pipeline and ball valve and connect fuel oil oil-in and oil return opening in each heat test platform, and then link to each other with the advancing of engine fuel house steward, oil return opening respectively through the hydraulic quick coupler of band retaining valve and flexible pipe; Fuel delivery subsystem and oil return subsystem all are power with the compressed air source, and compressed air source connects the pneumatic diaphragm pump of oil supply system and the air valve of return oil system respectively by pneumatic triple piece, have taken into full account the specific environment requirement of heat test like this.Below be two-part structure:
Oil supply subsystem comprises the hydraulic quick coupler and the flexible pipe of branch fuel tank, pneumatic diaphragm pump, in-line, ball valve, pressure regulator valve, oil pressure gauge, band retaining valve.Divide fuel tank to connect pneumatic diaphragm pump by pipeline, be connected with in-line on the output pipe of pneumatic diaphragm pump earlier, again after ball valve connects pressure regulator valve and oil pressure gauge, be connected to the other fuel oil oil-in of heat test platform, hydraulic quick coupler and the flexible pipe through the band retaining valve is connected to engine fuel house steward oil-in again.
Oil return subsystem comprises oil sump tank, pneumatic diaphragm pump, air valve, high and low level controller, High High Level alarm, ball valve and return line.Oil sump tank connects the pipeline from the other return flow oil mouth of heat test platform, links to each other with engine fuel house steward oil return opening with flexible pipe by the hydraulic quick coupler of being with retaining valve.Be provided with high and low position control probe and High High Level control probe in the oil sump tank, connect pneumatic diaphragm pump on the pipeline road of oil sump tank, be connected to air valve on the air inlet pipeline of pneumatic diaphragm pump, air valve is connected control by high and low level controller, High High Level alarm respectively, and pneumatic diaphragm pump is directly sent into the fuel oil of oil sump tank in the branch fuel tank of oil supply subsystem by pipeline road.
For further improving the security of this system, between the pneumatic diaphragm oil pump outlet line road of oil supply subsystem and pressure regulator valve in the pipeline, set up the turnout, in case oil feed line exceeds standard because of the pipe internal pressure, produce the pipeline explosion, potential safety hazard occurs and back pressure regulating valve is installed, the fuel-displaced pipeline of back pressure regulating valve inserts the oil sump tank of oil return subsystem.
The principle of work of native system:
At first the pneumatic diaphragm pump by oil supply subsystem is power with pressurized air, fuel oil in minute fuel tank is delivered to by the heat test by pre-buried pipeline, through ball valve, pressure regulator valve, oil pressure gauge, deliver to the fuel oil oil-in, then through the band hydraulic quick coupler of retaining valve and flexible pipe to engine fuel house steward oil-in fuel feeding.Enter the engine fuel house steward not usefulness fuel oil from engine fuel house steward oil return opening through flexible pipe, the band retaining valve hydraulic quick coupler and pipeline will not flow back to (500 absolute altitude) in the fuel tank automatically with fuel oil, high and low position control probe is housed in the oil sump tank, when the pasta rising touches high position control probe, the pneumatic diaphragm pump of oil return part just starts automatically, fuel oil in the oil sump tank is pumped in the branch fuel tank by pipeline, the pasta of oil sump tank reduces gradually, when pasta left low level controller probe, pneumatic diaphragm pump just quit work automatically; Malfunctioning for preventing high-order controller, also be provided with High High Level controller probe, the alarm that links with it is installed in by the testing table operator, in case report to the police, the fuel feeding district that can send someone immediately safeguards.After the oil pressure in the pipeline road of fuel feeding part surpasses setting, by the back pressure regulating valve releasing pressure automatically, fuel oil is introduced in the oil sump tank automatically, further improve the security of system.
In addition, also be provided with oil-water separator at compressed air source towards between the pipeline of pneumatic triple piece.Effectively improve the pressurized air quality, prevent that moisture from entering in the pipeline.
The utility model will carry out centralized arrangement away from the heat test zone for, oil return part, and can satisfy a lot of hot experiment tablees needs of fuel feeding, oil return simultaneously simultaneously, and will be not only safe in utilization, and be convenient to production-scale expansion; In system,, back pressure regulating valve, high and low level controller, High High Level alarm etc. are set, the security that improves system also by adopting the compressed-air power source.Therefore native system is reasonable in design, and security is good, and reliable operation can be widely used in automobile, motorcycle, machine industry peculiar to vessel.
