Abstract
A processing technology for an inner container of a vehicle-mounted LNG cylinder comprises a preheating step, a winding step, a reinforcing step and a sleeving step. The inner container of the gas cylinder is firstly preheated and dried in a drying box, and preheating temperature is 110-130 DEG C; and then the inner container is conveyed out and enters a cold air chamber to be subjected to winding of heat preservation materials, a copper wire is adopted for further reinforcing the outer layer after winding, and during sleeving, a clearance formed by the inner container and an outer barrel is vacuumized, and the vacuum degree of the clearance is guaranteed. The inner container is processed through a four-step method, the drying condition of the inner container of the gas cylinder is fully guaranteed, and vacuumizing of the last step is facilitated. The copper wire is used for reinforcing the heat preservation materials, so that the heat preservation materials are protected, and the heat insulation effect is controllable; and later vacuumizing operation is facilitated better, and labor force and production cost are reduced.
Description
Technical field
The present invention relates to gas cylinder apparatus field, be specifically related to a kind of processing technology of LNG vapour carrier gas bottle inner bag.
Background technique
Vehicle compressed natural gas cylinder is a kind of economy, safety, environment protection type automobile-use gas storage equipment, along with the continuous change of international oil price, vehicles number sharply increases, the enhancing gradually of people's environmental consciousness, the rock gas as clean energy resource is applied widely in the field such as city bus, Automobile Transportation.
LNG mounted gas cylinder is as a kind of low-temperature heat-insulation pressure container, be generally double-layer vacuum structure, inner bag is used for storing the LNG Liquefied natural gas of low temperature liquid, multilayer heat insulation composite bed is wound around at its outer wall, make it have superpower heat-shielding performance, chuck simultaneously between inner bag and urceolus is pumped into high vacuum, the adiabatic system that common formation is good.Therefore the technique that the outer wall of inner bag is wound around and operation that inner-outer tube space is vacuumized just very crucial.Traditional technique is directly on the outer wall of inner bag, be wound around one deck heat-insulating material, and the thermoinsulation material be wrapped in the assembling process to inner bag and urceolus on inner bag often easily damages, and has had a strong impact on the heat-insulating property of gas cylinder.And; workman is in the process of processing inner bag; sweat drops onto on the steel of inner bag; moisture in sweat and grease are present in steel can increase the work difficulty and time that the later stage vacuumizes; in order to ensure that the degree of vacuum in the space of inner bag and urceolus just can waste time and energy within the scope of setting; the cost of production of at substantial, is unfavorable for the large-scale production of enterprise.
The problems referred to above should be paid attention to and the problem solved to the design of the technique used in LNG mounted gas cylinder inner bag course of working.
Summary of the invention
For above-mentioned Problems existing, the invention provides a kind of LNG mounted gas cylinder inner bag processing technology.
Technical solution of the present invention is: a kind of LNG mounted gas cylinder inner bag processing technology, comprises preheating step, winding step, reinforcing step and suit step, adds man-hour, carry out according to following concrete steps inner bag:
Preheating step: after cylinder liner is shaping, enters in baking oven by inner bag whole Transporting, and the steel being made into inner bag carry out preheating in an oven, and preheating temperature is 110 DEG C ~ 130 DEG C;
Winding step: after warm-up operation terminates, takes out inner bag from baking oven, is transported to cold air chamber, adopts Stetch Wrapping Machine to be wound around inner bladder outer wall by thermal insulating material;
Reinforce step: adopt copper wire to be wound around further at thermal insulating material outward, reinforce the winding of thermal insulating material;
Suit step: the inner bag after reinforcing is sleeved in urceolus, the space vacuum pumping form of inner bag and urceolus.
Further improvement of the present invention is: the described thermal insulating material in winding step comprises glass fiber paper and aluminium foil.
Further improvement of the present invention is: in suit step, the degree of vacuum in inner bag and urceolus space is 2.7 × 10
-5pa.
A kind of LNG mounted gas cylinder of the present invention inner bag processing technology, the steel preheating making cylinder liner is first dried by cylinder liner in an oven, moisture in steel is also evaporated dry, and then inner bag transported and enters cold air chamber and carry out traditional thermal insulating material and be wound around, and adopt after being wrapped over copper wire be wrapped in further thermal insulating material skin inner bag entirety is reinforced, just can be set with inner bag and urceolus after a whole set of operation terminates, be evacuated in the space that inner bag and urceolus are formed and ensure the degree of vacuum that need meet.
The invention has the beneficial effects as follows: the present invention adopts four step methods to process inner bag, many compared to traditional mode of operation preheating steps and reinforce step, adopt preheating step by the moisture evaporation in inner bag steel, afterwards inner bag is transported directly to cold air chamber, preventing workman from course of working, easily flowing down sweat drops onto on gas cylinder, the technique of the design fully ensure that and is beneficial to the carrying out that final step vacuumizes by the drying regime of cylinder liner.Adopt copper wire to reinforce thermal insulating material, not only have protective action to thermal insulating material, and can control insulation effect, elasticity is moderate, and outgassing rate is little, is also more conducive to the vacuum pumping in later stage, saves labour force and cost of production.
