Description
Technical field
The present invention relates to a kind of fixed support, particularly relate to a kind of natural gas used for automobile tank fixed support.
Background technology
Natural gas-powered car changes with oil a kind of gaseous fuel automobile that natural fuels is fuel.Natural gas methane content, generally more than 90%, is a kind of well automotive engine fuel.What Zhengzhou City started to apply for 2012 is to use compression natural gas or gasoline compression natural gas-gasoline dual-purpose fuel automobile respectively, is called for short CNG automobile, also will widely popularize from now on and apply single fuel natural gas automobile.The pressure of compressed natural gas used as vehicle fuel is generally at about 20MPa.By natural fuels, after dehydration, desulfurizing and purifying process, can obtain through multistage pressurization.State when it uses is gas.Natural gas-powered car is clean fuel automobile.The exhaust emission of natural gas-powered car is significantly less than gasoline-fueled automobile, not sulfur compound and lead in tail gas, and carbonic oxide reduces by 80%, and hydro-carbon reduces by 60%, and Nitrogen oxides reduces by 70%.Therefore, many countries using Natural Gas Motor Vehicle as a kind of important means alleviating atmospheric contamination.Natural gas-powered car has significant economic benefit.Exploitation of automobile cost can be reduced, the cost ratio gasoline of natural fuels and diesel oil much lower, fuel cost generally saves about 50%, and operating cost are significantly reduced.Due to the existence of oil gas price difference, changing fare can regain within 1 year.Service expenditure can be saved.Driving engine uses natural fuels to do fuel, operates steadily, noise is low, not carbon deposit, can increasing service life of engine, does not need often to change machine oil and light-up plug, can save the service expenditure of more than 50%.More safer than gasoline automobile.First compared with gasoline, the fuel that compression natural gas is inherently safer.This shows: burning-point is high.Natural fuels burning-point, at more than 650.c, exceeds 223.c than gasoline burning-point (427.c), so not easily light compared with gasoline.Density is low.Be 0.48 with the relative density of air, gas leakage distributes very soon in atmosphere, is difficult to form the concentration of meeting fire burning.Antiknock property is high.Can reach 130, more much higher than No. 96 best at present MON Motor Octane Number, anti-detonating quality is good.Explosive limits is narrow.Only 5-15%, under natural environment, forms this condition very difficult.Dispose procedure is an endothermic process.When compression natural gas releases from container or pipeline, let out around hole and can form a low-temperature space rapidly, make combustion of natural gas difficulty.
The principle of work of natural gas-powered car is consistent with the principle of gasoline automobile.In brief, natural fuels mixes with air in the cylinder of four-stroke motor, by spark-plug ignition, promotes piston and moves up and down.Although natural fuels is compared with gasoline, there are some difference in comb. and ignition temperature, and what natural gas-powered car adopted is the operation scheme basically identical with gasoline car.Use compression natural gas to carry out air feed to run mostly.Natural fuels is compressed to 20-25MPa, and then pumps into the high pressure tubular gas cylinder being connected to automobile rear, top or support.The flask volume of early stage natural gas-powered car is very large, occupies a large amount of boot spaces, but has developed lightweight gas cylinder of new generation.
The principle of starting of natural gas-powered car is, when after natural fuels automobile engine starting, natural fuels imports fuel from gaholder by flexible pipe, and near driving engine, natural fuels will enter pressure regulator thus realize step-down.Then, natural fuels will enter multipoint sequential injection spray rail, and gas can be introduced in cylinder by this spray rail.Sensor and computing machine regulate to the miscellaneous gas of fuel and air, so that during spark ignitor natural fuels, burn more effective.Natural gas engine also comprises reflectal, high compression piston, nickel tungsten hardening agent exhaust valve seat and methyl hydride catalyzed converter.
Existing natural gas tank fixed form generally adopts a circular arc fixed strip, and two ends adopt the mode of riveted joint to be fixed on car body, not only dismantle inconvenience, and vibrations are severe in vehicle travel process, and natural gas tank easily damages, and fixed effect is general.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of and install simply, good damping effect, noise is little, and constant intensity is high, is suitable for the natural gas used for automobile tank fixed support of different size.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of natural gas used for automobile tank fixed support, comprises the rectangular seat that has U-type groove and is positioned at the clip be fixedly connected with base above base; The U-type groove bottom level of described base has a groove, and described groove internal fixtion is provided with shock absorption device; The U-type groove right-hand member of described base vertically has a square column hole, and be inserted with a square column in described leghole, the sliding nut that described column is installed by base side is flexibly connected with base; Described clip structure is a flat circular arc anchor ear, and described anchor ear one end is fixedly connected with column upper surface by screw A, and the described anchor ear other end is fixedly connected with the U-type groove left side of base by screw B.
Further, described shock absorption device is any one in damping spring or Rubber shock-absorbing pad.
Further, described anchor ear is flexible metal strip semicircular ring structure.
Further, described anchor ear medial surface is installed with some well-distributed nonslipping spurs.
Further, the rubber pad with its form fit is placed with in the U-type groove of described base.
Beneficial effect of the present invention is as follows:
1. the present invention carrys out horizontal placement natural gas tank by U-type groove base, the vibrations bringing natural gas tank in automobile traveling process are reduced by shock absorption device, utilize a column that can move up and down to adapt to the natural gas tank of various outer diameter specification simultaneously, natural gas tank is put in after in U-type groove, according to natural gas tank various outer diameter size, column is moved to differing heights, utilize the sliding nut of base side to prop up column side and column is fixed on desired height, then the anchor ear other end and base left side are fixed, the nonslipping spur of anchor ear medial surface plays anti-skidding effect, this fixed support is not while affecting constant intensity, the natural gas tank of different size can also be suitable for, reach antiskid, shock-absorbing, reduce the object of noise, be beneficial to user vehicle to promote the use of on a large scale.
