Description
Technical field
The invention belongs to workpiece cleaning means field, more particularly, to a kind of two cylinder compression pumps.
Background technology
A kind of equipment of the compression pump as conveying high-pressure liquid or gas is widely used in workpiece cleaning field, passes through height
The liquid of spray gun output or the gas entrainment cleaning sand of High voltage output is pressed to carry out depth cleaning to workpiece surface so that workpiece obtains
While cleaning, parts will not cause to wear.
But compression pump currently on the market is usually multiple plunger pumps to be laid side by side, such as Chinese patent CN 201546936
A kind of horizontal arrangement hydraulic diaphragm high-temperature high pressure pump of five plungers is disclosed, is in horizontal five plungers of arranged distribution on the pump housing
Mounting hole, the interior installation plunger of plunger mounting hole；Bent axle can be reduced as Chinese patent CN 2013207336762 discloses one kind
Five piston high-pressure pump power of torque, five connecting rods are laid side by side.
Also it is that three plungers are circumferentially uniformly distributed to have compression pump, as Chinese patent CN 206617290 discloses one kind three
Piston reciprocating type high-pressure high-flow slush pump, including the pump housing, the inside of the pump housing is hollow cavity, and one is respectively welded on three sides
A plunger recreation room connected with hollow cavity, there are one cylinder, each cylinders for each fixation of plunger recreation room external end
Piston rod be inserted into corresponding plunger recreation room and be connected with the indoor piston of plunger activity with piston in plunger recreation room
Inside move reciprocatingly.
The compression pump of above two structure in actual use, in order to realize the continuity of injection, sets multiple phases
The plunger pump that neighbour lays, entire compression pump is brought rapidly up during work so that the heat dissipation around each plunger pump is extremely uneven, sealing
Circle abrasion everywhere is inconsistent, expansion and shrinks all uneven, accelerates the abrasion and aging of sealing ring, reduced service life,
Lead to gas leakage, and then cause the cleaning required target injection pressure of parts is not achieved.
Invention content
For overcome the deficiencies in the prior art, a kind of heat dissipation of present invention offer is uniformly, injection pressure is high, power saving, makes
With two cylinder compression pumps of long lifespan.
The technical solution adopted by the present invention to solve the technical problems is：A kind of two cylinder compression pumps, including the first plunger pump
Interlock with the second plunger pump and the first plunger pump of driving and the second plunger pump and export the driving device of highly pressurised liquid, described the
One plunger pump is made of the first cylinder body and the first plunger, and the side wall of first cylinder body is cylindrical structure, the side of the first cylinder body
Wall uniform wall thickness, the first plunger are packed into from the first end of the first cylinder body, and the second end of the first cylinder body is equipped with the first low pressure inlet
With the first high pressure liquid outlet；Second plunger pump is made of the second cylinder body and the second plunger, and the side wall of second cylinder body is
Cylindrical structure, the side wall uniform wall thickness of the second cylinder body, the second plunger are packed into from the first end of the second cylinder body, and the of the second cylinder body
Two ends are equipped with the second low pressure inlet and the second high pressure liquid outlet；The first low pressure inlet, the first high pressure liquid outlet, second
Check valve is equipped on low pressure inlet and the second high pressure liquid outlet, the first high pressure liquid outlet and the second high pressure liquid outlet connect
Connect total liquid outlet, the relatively independent setting of side wall of the side wall and the second cylinder body of first cylinder body.
Existing compression pump usually sets multiple plunger pumps, plunger pump four to realize the continuity of high-pressure liquid jet
The heat dissipation of week everywhere is not uniform enough, and the side wall heat dissipation for leading to plunger pump is uneven, and the temperature of cylinder barrel everywhere is inconsistent, and plunger pump is affixed
Near part side wall heat dissipation effect is poor, the sealing ring uneven heating in cylinder barrel, and the expansion and contraction of sealing ring are uneven, lead
The abrasion of fine and close seal everywhere is inconsistent, generates gas leak phenomenon, and then causes to spray the decline of pressure or even cause stress pump
Damage；The abrasion of sealing ring everywhere is inconsistent, shortens the service life of sealing ring, accelerates the replacement cycle of sealing ring, and then subtracts
The service life of short compression pump.

Fill in synchronous reciprocating movement.
The present invention only needs a piston that the first plunger pump and the second plunger pump is driven to move simultaneously, when piston drives first
When plunger pump pumps out highly pressurised liquid, required power is smaller when liquid is extracted in the movement of the second plunger pump, therefore power more supernumerary segment
It saves；And it is simple in structure, do not need to complicated transmission mechanism；First plunger pump and the second plunger pump are coaxial, are symmetricly set on liquid
The both sides of cylinder pressure so that the spacing around the first plunger pump and the second plunger pump is maximum, and the space with enough abundances is dissipated
Heat, heat dissipation effect reach best, and the service life of compression pump is extended.
Further, the first cavity, the first low pressure inlet and the first cavity phase are formed in first cylinder body
Connection；The second cavity is formed in second cylinder body, the second low pressure inlet is connected with the second cavity；The hydraulic pressure
Cylinder includes piston, the First piston bar for being respectively arranged on piston both sides and second piston bar, cylinder barrel, First piston bar driving the
One piston reciprocation moves, and the second piston bar drives the movement of the second piston reciprocation.
First piston bar directly drives the first plunger, and second piston bar directly drives the second plunger, without other connection knots
Structure, structure composition is simple, the small volume of entire compression pump.
Further, the aperture of the first high pressure liquid outlet is less than the aperture of the first cavity；The second high press juice
The aperture of mouth is less than the aperture of the second cavity.It is obtained according to pressure formula p=F/S, area S=π r2, due to the first high pressure liquid outlet
Aperture be significantly smaller than the internal diameter of the first cavity, r is about 1 with respect to the internal diameter of the first cavity：10, so as to which pressure exponentially becomes
Gesture increases, and has reached the suddenly change by internal diameter, has increased the purpose of the discharge pressure of high-pressure outlet, has considerably increased water outlet
Dynamics.
Further, the First piston bar and the first plunger are wholely set；The second piston bar and the second plunger one
Body is set.
Further, first cylinder body, cylinder barrel, the second cylinder body are wholely set.
Further, high pressure chest, the first high pressure liquid outlet are equipped between first plunger pump and the second plunger pump
It is set with the second high pressure liquid outlet face, the first high pressure liquid outlet and the second high pressure liquid outlet are connected by the high pressure chest.
Further, the height of the high pressure chest is more than the aperture of the first high pressure liquid outlet.
Further, the first power source is connected on first plunger pump, second is connected on second plunger pump
Power source, first power source and the second power source respectively drive the first plunger pump and the second plunger pump is synchronized with the movement, at this time
First plunger pump discharges medium from the first low pressure inlet extracting medium, the second plunger pump to the second high pressure liquid outlet.
