Description

A kind of air respiratorresuscitator filling pump of cylinder body band cooling unit

Technical field

The utility model relates to a kind of air respiratorresuscitator filling pump.

Background technique

Because a large amount of popularization and applications that high pressure is implemented make original high pressure packing equipment and technology can't adapt to people's demand.Air filling pump is a kind of gas collecting compression device, being widely used in the fireman speedily carries out rescue work with fields such as air respiratorresuscitator filling, military affairs, space flight, boats and ships, oil, chemical industry, pipe detection, applied voltage tests, for example: do not have the use of can't remaining valid of existence all air respiratorresuscitators in the world of high pressure packing pump, pipeline pressure in the West-East National Gas Transmission Project of China detects also can't be finished, and the pressurized gas of breathing for the astronaut in No. seven, divine boat is also realized by the high pressure packing pump.So because the particularity of this product is extra high to its each workpiece performance requirement.

Air respiratorresuscitator filling pump is made up of compressor set, drive motor, filter assemblies, base plate and support etc. usually.Compressor set is made up of the manometric joint etc. that charges of multistage compression cylinder, safety valve, multistage filtering and oil-water separation air cleaning unit (air intake filter, intermediate separator, central filter assembly), condensed water escape cock, snakelike pipeline, cooling fan, pressure retaining valve and band final pressure.Air filling pump pressure contracts and fan is housed on the machine crankshaft end, in order to from suck air cooling compressor cylinder and snakelike pipeline on every side.The multistage compression cylinder promotes air pressure step by step by 0; Every grade of cylinder constitutes by cylinder block and cylinder valve head.Radiator is arranged on the cylinder block, in members such as piston, connecting rod are arranged.The cylinder valve head is the top of cylinder, and suction valve and pressure plate valve are equipped with in the inboard, and valve is controlled opening and closing automatically by media flow, and during induction stroke, INO, medium flow in the cylinder; When compression stroke began, suction valve cut out, and medium is opened pressure valve, and every grade of cylinder cylinder is respectively different diameters.

Yet this series products of producing, use both at home and abroad all can't guarantee to realize the requirement of continuous non-stop run at present, because the design deficiency of compression cylinder so just improves the fast development that cost of production has restricted related domain greatly.Use existing such technical equipment to finish continuously as needing owing to some special occasions, will occur causing the serious damage of compression cylinder part of filling pump to be scrapped as continuous use owing to compression cylinder can not get effectively fully heat radiation, be forced to cease operation when serious with entail dangers to person life safety.Because the method for cooling is mainly fan, devices such as radiator, well-known high pressure packing pump is to utilize the principle of machinery that the volume compression of gas will be used to certain ratio supply and demand, thereby the principle that adds mechanical friction of dwindling suddenly owing to gas volume in the compression process of gas produces a large amount of heat, gas can generate heat rapidly through overcompression and make this equipment can't bring into play best effectiveness because the gas that principle of expanding with heat and contracting with cold makes has increased frictional force, because the accumulation of heat can not get effectively fully discharging and makes machinery proper functioning continuously, cause the air respiratorresuscitator filling pump can't proper functioning, poor reliability.In addition,, can not be cooled at once, can cause pressurized gas temperature height, and can not use at once because the heat of cylinder body is big.
