Gasoline cutting machine

Gasoline cutting machine introduction [words]: gasoline welding machine (phonetic): qìyóu qiēgējī

[Introduction]: Gasoline cutting machine is a high-efficiency tool for the flame processing of metal by high-temperature flame produced by gasoline without pressure self-priming, oil-oxygen high atomization and mixed combustion. Gasoline cutting machine components Gasoline cutting machine mainly consists of three parts: Explosion-proof gasoline tank, oil hose and gasoline torch Gasoline cutting machine working principle Gasoline cutting machine adopts the principle of injection and suction torch, oxygen gas will be transported to the cut The mouth is atomized and mixed with oxygen in a certain proportion to ignite. No need for electricity, no need to pressurize the gasoline, overcoming the cumbersome preparations before use. The structure of the torch is reasonable, and the position of the oxygen and oil valve is exactly the same as that of the acetylene torch, and the operator adapts quickly. Gasoline tanks work under normal pressure, cutting thickness 1-40mm, no gasoline spills, thus maximizing the stability of the flame during cutting.

The main advantages of gasoline cutting machine:

First, the cost is low:

Gasoline used in gasoline cutting machines is an economical fuel. It has been verified that the workload of 3 liters of gasoline (about 18 yuan) is equivalent to 1 bottle of acetylene (about 90 yuan), saving more than 80%, with propane, liquefied petroleum gas, and Xiapu gas phase. More than 50% savings.

Second, the operation is simple:

No electricity, no need to pressurize the oil storage tank, overcome the cumbersome preparatory work before use, the torch body structure is reasonable, the operation is simple and fast, and greatly simplifies the on-site cleaning work after use.

Third, reliable safety performance:

Gasoline cutting machine from the gasoline tank to the cutting nozzle is a liquid, the liquid is not tempered, so the machine absolutely will not be tempered, the gasoline tank filled with the national Ministry of Public Security, Ministry of Labor recommended high-tech explosion-proof materials, even if Gasoline directly ignited in a gasoline tank can only slowly burn gasoline, and it will not cause severe combustion and explosion. (An oil tank containing this explosion-proof material can even be used to repair the oil tank with a gap.) Another experiment confirmed that during the work of the torch, even if the oil pipe is suddenly cut off, the torch will continue to work for a few minutes until it runs out of gasoline in the pipeline and there is no risk of gasoline splashing that could endanger people’s safety. It is unmatched by other gasoline torches. Gasoline tanks are equipped with constant-pressure constant pressure relief valves. On the one hand, they can eliminate the negative pressure generated in the tanks after long-term operation of the tanks. On the other hand, they can ensure that gasoline in tanks will not fall when gasoline tanks are accidentally dumped. Leaked out.

Fourth, the cutting quality is good:

The use of gasoline cutting torch to cut the edge of the steel without undercutting, burning collapse, the following no nodules, slag, smooth and clean cutting surface easy to clean, and the surface will not occur carbonation and hardening phenomenon, greatly reducing the material waste during processing And processing difficulty.

V. Wide applicability:

It can be used for cutting, welding and heating of various thickness carbon steels. It can also be applied to hot melt processing and flame treatment of gold and silver jewelry, glass, quartz, electronic products and stone. It is widely used in metallurgy, shipbuilding, boilers, automobiles, etc. Machinery processing, chemical industry, construction, agricultural machinery, agricultural machinery maintenance and other fields, the market has broad application prospects, can handle, semi-automatic, profiling, baking torch cutting and heating, the maximum cutting thickness of 300mm, welding torch can be used for welding 1-5mm steel plate, silver welding, brazing, brazing and non-ferrous metal welding.

Six, the work speed:

Gasoline torch flame temperature up to 3000-3300 degrees, short warm-up time cutting, cutting speed. It has been verified that cutting 20mm thick steel plates at 20°C can achieve cutting speeds of up to 500mm/min. The gas fired torches are concentrated in firepower. They can save 30-50% more time for heating workpieces than acetylene, and can save more than 90% energy.

Seven, convenient transportation:

Gasoline cutting machine is mainly composed of explosion-proof gasoline cans, oil hoses, torches and torches. The overall weight is only 6kg, which is very convenient for transportation and transportation. At the same time, gasoline can be purchased anywhere and transportation is convenient and easy.

Eight, green protection:

The wide application of this product is bound to save the country a lot of electrical energy and mineral resources, directly reduce the pollution of acetylene to the natural environment, this product does not produce residual oil, black smoke and other harmful substances in the application process, does not cause pollution harm to the environment It can be said that the work is in the contemporary era and it will be beneficial to the future.

Gasoline cutting machines cause fire accident prevention measures 1. Causes of fire accidents 1. Unauthorized jobs. Many construction companies, especially individual contractors, often save money, save time, and pursue more profits. They often employ electric welding workers who have not undergone formal firefighting training and assessment. Most of them belonged to process workers. Most of them were not trained before the job and lacked knowledge of fire safety. They were blind and obstinate, resulting in a fire accident.

Second, operators lack safety knowledge. According to the relevant data, the high temperature generated during welding can reach 3000-6000°C, and there are a large number of sparks and hot iron splashes, especially when welding in infrastructure, temporary sites and non-dedicated rooms. Mars can easily cause fire if it falls on flammable materials. After the metal components are welded, the temperature is very high. Even after a certain period of time, it may still ignite the surrounding combustible materials. If it is not to be cooled after welding, it will be stored casually, which can also cause combustibles. Burning; the high heat energy generated during welding is conducted to the other end by the metal member, which can cause combustibles at the other end of the metal member to burn; the earthing loop of the welding machine has a large resistance due to the connection, can generate resistive heat, or is When arcing, a spark may be generated due to the impact current, and it may also ignite combustibles.

Third, a few operations neglect fire safety. Some individual contractors have weak awareness of fire protection and are unwilling to invest manpower and funds in the safety protection of electric welding operations. They even disregard the relevant laws and regulations of the state, fail to follow regulations, do not follow the instructions, and do not obey the regulations and operate illegally. They opposed the reduction of costs to the establishment of a sound labor production safety standard, unilaterally emphasized profits, neglected safety inputs, and could not correctly understand that the latter is the prerequisite and fundamental guarantee for the realization of the former, and the former is the inherent result of the latter's inevitable result. . In some major fire accidents, welders are ideologically paralyzed during operations, and their awareness of prevention is weak. When accident hazards have been threatened, they have not received enough attention and no preventive measures have been taken, which ultimately led to accidents.

2. Measures to Prevent Fire Accidents Caused by Gasoline Cutting Machines 1. Strengthen source management and ensure that welding and cutting operators hold certificates. Strengthen the education and management of welders, enhance their sense of responsibility, and strictly manage the welding equipment and operations. Welding operations must be carried out by trained and certified welders and strictly observe the operating procedures. Welders should also be regularly informed about fire protection and fire protection. Locations where electric welding operations are carried out frequently shall be posted with instructions on fire protection and related fire prevention regulations. Each construction and construction unit shall strengthen the inspection of the qualifications of the welding and cutting personnel. Before the construction, the construction personnel shall issue the relevant certificates, and the personnel found to be unlicensed in the inspection shall resolutely cancel their qualifications for electric and gas welding operations. There can be no luck to ensure that the welding and cutting operators hold certificates.

Second, a clear responsibility for safety, enhance the construction workers' awareness of fire prevention. Establish a responsibility system for key job types, so that personnel engaged in welding job positions have clear responsibilities, and establish a reasonable, effective, and civilized safe production and work order, and be linked to the rewards and punishments system. The phenomenon. When signing a construction contract, the construction and construction unit must add fire prevention work clauses. If a fire or other accident occurs due to a violation of the safety operation rules during the construction, the liability shall be clearly stated in advance, and the issue shall be investigated closely so that the construction unit and personnel are ideologically Pay attention to fire safety, and consciously do a good job of fire prevention work.

Functional departments such as safety supervision, public security, and fire protection shall strengthen the prevention and control of the social security situation, intensify inspections, focus on the inspection of “five small” places, discover hidden dangers of various types of safety accidents, and reduce the chance of accidents.

Third, strengthen publicity and education to improve employees' awareness of fire prevention. First, strengthen pre-job learning and training for employees. Clearly stipulates that the following five conditions shall not be used: welding shall not be carried out in places where there is a risk of fire or explosion; in and around the trenches, pits, and sewers where combustible gases and flammable vapours are stored, it is not possible to proceed without eliminating risk factors. Welding operations; no welding operations shall be carried out on hollow partition walls, places filled with flammable insulation, simple buildings, simple warehouses, stuffy roofs with flammable building elements, and combustible combustible material stacks; weldments Before the internal structure, properties, and deposits are known, and before the flammable liquid remaining in the metal container is not treated, the welding operation must not be performed; in the room where flammable and explosive dangerous goods are produced, processed and stored, the storage is easy. Storage tanks and containers for explosive materials, live equipment, and newly-painted building components or equipment shall not be subjected to electric welding operations unless appropriate safety measures are taken. Secondly, through propaganda and reporting on fire accident cases, employees' awareness of fire protection is enhanced, they become passively active, and they consciously perform fire prevention work. Through demonstration of fire fighting skills for employees, they have certain knowledge of fire prevention and fire fighting, and they will report to the police. Proper use of fire extinguishing equipment will properly save the initial fire. Again, strengthen the daily management of welding personnel. It is necessary to regularly strengthen the technical training and knowledge of fire protection for welding workers, and formulate practical and feasible learning, training and assessment plans to study and grasp the psychological status and bad behavior of welding workers, and help them to overcome smoking, drinking, and going to work. , gossip and other bad habits, and constantly improve the working environment and conditions to reduce the chance of accidents.

Fourth, strengthen on-site supervision to eliminate fire hazards. In the construction of the site, strict fire management system, strict implementation of safety precautions in electricity and gas welding operations. In the welding machine shell is provided with a reliable protection of zero; for the welder to set up a separate power switch; welding machine placed in a well-ventilated, dry, non-corrosive media, away from high temperature and humidity and dust, open-use use should be established Canopy; Welders should stand on a dry insulating board or pad when the construction welding site is wet. Workers should wear insulating shoes or stand on the insulating plate. When welding or cutting at high altitude, the safety belt must be fastened and welded around. The fire prevention measures shall be taken at the lower part, and special persons shall be supervised; during the operation, it shall be ensured that no explosive materials are piled up within 10m around the site of the welding operation. The sparks of spatter will not fall into the lower combustibles and ignite the combustibles. On-site guardians shall timely eliminate and strictly guard fire hazards discovered during the inspection to ensure fire safety at the construction site.
