Description

A kind of portable piston combined type high-pressure pump
Technical field
The utility model relates to air pump technical field, particularly relates to a kind of portable piston combined type high-pressure pump.
Background technique
Current mechanical industrial development is very fast, produce and in life, the demand of pneumatic product also got more and more, such as air pump and high-voltage detecting device, in order to the portability used, also need these pneumatic products to have higher air pressure generation performance and less volume simultaneously; For flight-line maintenance, inevitably use high-pressure pump and in high pressure pipe line or container, be filled with the pressurized gas of certain pressure to realize the leak detection of high pressure pipe line; But detection facility volume of the prior art is usually comparatively large, can only send factory's maintenance back to needing the parts detected to remove, not only power consumption is comparatively large, working efficiency is lower, wastes a lot of manpower and materials simultaneously.
Model utility content
For solving the problems of the technologies described above, the utility model provides the portable piston combined type high-pressure pump that a kind of portability is higher, can produce pressurized gas simultaneously.
One of the present utility model portable piston combined type high-pressure pump, comprises power plant, one-level cylinder, secondary cylinder and one bent axle; The fixed end of described one-level cylinder is provided with the contrary large discharge suction valve of gas flow and the first one-way valve and movable end is provided with piston, and described piston is connected with described one crankshaft eccentric; The fixed end of described secondary cylinder is provided with the contrary breather check valve of gas flow and the second one-way valve and movable end is provided with plunger, and described plunger is connected by camshaft bearing with described one bent axle; Be connected by suction tude between described first one-way valve and breather check valve, described power plant are connected with described one transmission of crankshaft.
Further, the bottom of described plunger is also provided with the grease cylinders of hollow structure, one end and the described secondary cylinder of described grease cylinders are fixedly linked, and be provided with high pressure resistant flower bud type circle and nylon pad between described grease cylinders and described secondary cylinder, described grease cylinders is communicated with lubricating oil tank, is provided with high-temperature explosion-proof lubricant oil in described lubricating oil tank.
Further, described secondary cylinder is tetrafluoro cylinder, and described plunger is chrome-plated plunger.
Further, described power plant are d.c. motor, alternating current motor or internal-combustion engine.
Further, the outside of described second one-way valve is communicated with oil and water seperator.
Compared with prior art the beneficial effects of the utility model are: one of the present utility model portable piston combined type high-pressure pump, simply light, substantially easily damaged parts is not had, pressure high (the highest 40MPA), the life-span is long, and matching gap is little, gas circuit is short, drive with small power DC or alternating current motor or compact internal combustion engine, can normally use in any environment, be applied to high pressure pipe line, container leak detection, diving articles for use gas make-up etc.; Secondary high pressure cylinder camshaft bearing drives, and single load bearing, decreases wearing and tearing, extends working life; In addition, tetrafluoro cylinder is with self-lubricating effect, and high temperature resistant, and secondary cylinder still can be worked lastingly under rugged environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, one of the present utility model portable piston combined type high-pressure pump, comprises power plant, one-level cylinder 1, secondary cylinder 2 and one bent axle 3, the fixed end of one-level cylinder 1 is provided with the contrary large discharge suction valve of gas flow 4 and the first one-way valve 5 and movable end is provided with piston 6, and piston 6 is connected with one bent axle 3 bias, the fixed end of secondary cylinder 2 is provided with contrary the keeping away gas one-way valve 7 and the second one-way valve 8 and movable end is provided with plunger 9 of gas flow, and plunger 9 is connected by camshaft bearing 10 with one bent axle 3, and secondary cylinder 2 is tetrafluoro cylinder, and plunger 9 is chrome-plated plunger, be connected by suction tude 11 between first one-way valve 5 and breather check valve 7, power plant are in transmission connection with one bent axle 3, and power plant are d.c. motor, alternating current motor or internal-combustion engine, the bottom of plunger 9 is also provided with the grease cylinders 12 of hollow structure, one end and the secondary cylinder 2 of grease cylinders 12 are fixedly linked, and be provided with high pressure resistant flower bud type circle 13 and nylon pad 14 between grease cylinders 12 and secondary cylinder, high pressure resistant flower bud type circle and secondary cylinder are affixed, high pressure resistant flower bud type circle nylon pad compresses, to guarantee sealing effect, grease cylinders 12 is communicated with lubricating oil tank 15, high-temperature explosion-proof lubricant oil is provided with in lubricating oil tank 15, the bottom of plunger is connected with steel chrome-plated plunger cover usually, be used for being delivered to plunger logical for the power of camshaft bearing, plunger bushing moves up and down together with plunger, can constantly suck and extrude high-temperature explosion-proof lubricant oil in the process of motion, play the effect of lubrication and cooling high pressure resistant flower bud type circle.
Gas is moved downward by piston, air-breathing enters one-level cylinder, recompression enters secondary cylinder by breather check valve, the pressure of one-level gas promotes secondary plunger, make one-level cylinder carry the gas of coming to enter secondary cylinder, now the gas pressure of secondary cylinder reaches 2-5MPA, then by camshaft bearing, plunger is up pushed up, further supercharging, by the second one-way valve output high-pressure gas.
Portable piston combined type high-pressure pump of the present utility model, simply light, substantially easily damaged parts is not had, pressure high (the highest 40MPA), the life-span is long, and matching gap is little, gas circuit is short, drive with small power DC or alternating current motor or compact internal combustion engine, can normally use in any environment, be applied to high pressure pipe line, container leak detection, diving articles for use gas make-up etc.; Secondary high pressure cylinder camshaft bearing drives, and single load bearing, decreases wearing and tearing, extends working life; In addition, tetrafluoro cylinder is with self-lubricating effect, and high temperature resistant, and just secondary cylinder still can work lastingly under rugged environment.
In order to improve the degree of purity exporting gas, one of the present utility model portable piston combined type high-pressure pump; The outside of the second one-way valve 8 is communicated with oil and water seperator 16.
The above is only preferred implementation of the present utility model; It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model know-why, can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
