Abstract
The utility model relates to a single step dual cylinder hydraulic air pump. A supporting column is utilized to connect two pump bodies together, each pump body is provided with a gas inlet hole, a gas discharge hole, and an oil hole, and the gas discharge hole and the gas inlet hole are respectively communicated with a gas hole and a gas passage which are on respective one way valve of the gas inlet hole and the gas discharge hole. A gas chamber and an oil chamber are arranged on each of the one-way valves, a valve ball and a spring are arranged in the gas chamber, and a piston is arranged in the oil chamber. The gas can be discharged by high pressure by utilizing the pump bodies and the one-way valves. The utility model has the advantages of simple structure, high safety, high pressure and the ability of compressing various combustible and explosive gases.
Description
The utility model relates to a kind of hydraulic pressure air pump, particularly relates to a kind of single-stage double-cylinder hydraulic air pump.
Present various high-pressure service pumps that use, the motor and the pump housing are very near, if during the compression flammable explosive gas, set off an explosion easily.
The purpose of this utility model is exactly the single-stage double-cylinder hydraulic air pump that will provide a kind of pump housing to separate with motor.
The purpose of this utility model is achieved in that two pump housings are fixed together by pillar, is provided with piston in the pump housing, and the pump housing is provided with oilhole, inlet hole and exhaust port; Inlet hole and exhaust port are communicated with pore and air vent on the one-way valve separately respectively again, are provided with in the air chamber and cut down ball, cut down ball and contact with spring; Be provided with piston in the grease chamber of one-way valve, upper cover of piston rod has spring.
The utlity model has simple in structure, compressible various flammable explosive gas, safe and reliable, characteristics such as pressure is big.
Fig. 1 is the utility model structural representation.
Fig. 2 is the air pump structural representation.
Fig. 3 is the one-way valve structures schematic representation.
Describe the utility model in detail below in conjunction with accompanying drawing.
Two pump housings 1 are fixed together by pillar 2, and the pump housing 1 is fixed on the support 8, are equipped with piston 3 in each pump housing 1, and piston 3 is fixed on the piston rod 4.On the pump housing 1, also be provided with oilhole 5, inlet hole 6 and exhaust port 7, inlet hole 6 and exhaust port 7 are communicated with pore 10 and air vent 15 on separately the one-way valve 9 respectively, pore 10 is positioned on air chamber 11 walls, also have valve port 12 on air chamber 11 walls, valve port 12 is communicated with air vent 15, is provided with valve ball 13 in the air chamber 11, valve ball 13 can stop up valve port 12, and valve ball 13 also contacts with spring 14.Position relative with air chamber 11 on air vent 15 also is provided with grease chamber 16, has oilhole 17 and oilhole 18 on grease chamber's 16 walls.Also be provided with piston 19 in the grease chamber 16, piston 19 is fixed on the piston rod 20, is with spring 21 on the piston rod 20.Also be provided with projection 22,23 on grease chamber's 16 walls, but the stroke of limited piston 19.During use, hydraulic oil enters the pump housing 1 from oilhole 5, compression piston 3 motions, meanwhile, hydraulic oil also enters grease chamber 16 from oilhole 17, and compression piston 19 motions drive piston rod 20 valve ball 13 is backed down, and gas enters air chamber 11 from air vent 15 through valve port 12, by pore 10, inlet hole 6 enters in the pump housing 1 again; Pressurized gas in another pump housing 1 enters in the air vent 15 via exhaust port 7 simultaneously, when piston rod 20 backs down valve ball 13, is discharged by valve port 12 and pore 10.
