Degree, the medium of poor fluidity do not have turbulence pulsation phenomenon, pumping is steady, in sludge dewatering equipment to medium without shearing, without agitation
It is used widely in charging pump.
Existing plunger pump is twin-tub list feed mode, and piston rod is reciprocating always, but in the idle chamber side of working cylinder
It is easy to produce higher temperature, in order to solve this phenomenon, connects left and right sides work in structure by the way of welding cooling tube
Cylinder body, so idle chamber in two sides form reciprocal cooling water, are lubricated and cool down to piston seal, while reciprocal on
Cooling tube ceaselessly accesses cooling water, and lower cooling bottom of the tube is equipped with drain pipe port, can change in order to which the impurity in cooling water is discharged
It has been apt to cooling effect, has improved the operational efficiency of equipment.
However, the charging of twin-tub list is not able to satisfy duty requirements in large-power occasions, need for be all provided with material cylinder piston two sides
For working chamber, existing patent is the double feeding manners of twin-tub, is provided with 8 unidirectionally controlled valve groups and carries out flow, and be arranged
A series of outer pipelines, to cooperate the connection of one-way control valve.Either twin-tub list charging plunger pump or the double feed columns of twin-tub
Plug pumps, and more feed pipes and discharge nozzle are provided on plunger pump barrel, and feed inlet and outlet pipeline structure is complex, makes work
Skill is relative complex, extremely inconvenient for the installation and the maintenance in later period of early period；The double chargings of twin-tub simultaneously also need mating 8 unidirectional controls
Valve group processed, its structure is complicated, and equipment cost is high, while the consumptive material of operational process is more, increases the fault point of operation, increases
Operation and maintenance cost.
Summary of the invention
At low cost in order to solve the above technical problem, the present invention provides a kind of structure is simple, operation consumptive material is few, convenient for dimension
The double cylinder double acting hydraulic reciprocating pump of shield.
The technical solution adopted by the present invention is that: a kind of double cylinder double acting hydraulic reciprocating pump, in two material cylinders
Equipped with piston；Hydraulic cylinder and two material cylinders are coaxial, and hydraulic cylinder piston rod is connect with the piston in two material cylinders respectively；
Two material cylinders are located at the working chamber on the left of piston and are connected to by pipeline I, and it is logical that two material cylinders are located at the working chamber on the right side of piston
Piping II is connected to；Pipeline I connects feed-inputing branched pipe I and discharging branch pipe I, and pipeline II connects feed-inputing branched pipe II and discharging branch pipe II；
A check valve is respectively equipped on feed-inputing branched pipe I, feed-inputing branched pipe II, discharging branch pipe I and discharging branch pipe II.
In above-mentioned double cylinder double acting hydraulic reciprocating pump, the hydraulic cylinder is located between two material cylinders；Hydraulic cylinder
For double rod hydraulic cylinders, the both ends of hydraulic cylinder piston rod are connect with the piston in two material cylinders respectively.
In above-mentioned double cylinder double acting hydraulic reciprocating pump, feed-inputing branched pipe I and feed-inputing branched pipe II are connected to charging supervisor respectively；
Discharging branch pipe I and discharging branch pipe II are connected to discharging supervisor respectively.
Compared with prior art, the beneficial effects of the present invention are:
The configuration of the present invention is simple, working principle are simply clear；Two ipsilateral working chambers of material cylinder inner piston of the invention lead to respectively
Piping I, pipeline II are connected to, so that the control valve group group that feed pipe is connected with discharge nozzle is combined into two groups of control valves and is matched
Stream changes the control method that 4 medium conveyor chambers of double cylinder double acting sludge pump need four groups of check valves, i.e., by double cylinder double acting
Matched 8 one-way control valves of 4 medium conveyor chambers of sludge pump eliminate 4 one-way control valves, that is, use 2 groups of controls
Valve processed replaces 4 groups of control valves；The present invention reduces the quantity of pipeline and one-way control valve；Reduce consumptive material, reduce manufacture at
This, greatly improves working efficiency.Control method of the invention is simple and reliable, enormously simplifies system structure, reduces manufacture
Cost reduces the source of trouble and operation expense.
Detailed description of the invention
Fig. 1 is structure chart of the invention.
Specific embodiment
Following further describes the present invention with reference to the drawings.
As shown in Figure 1, the present invention includes two material cylinders 1,2 and a hydraulic cylinder 3；Divide in material cylinder 1 and material cylinder 2
It She You not piston 11 and piston 21；Hydraulic cylinder 3 and material cylinder 1, material cylinder 2 are coaxial, and hydraulic cylinder 3 is located at material cylinder 1 and object
Between material cylinder 2, hydraulic cylinder 3 is double rod hydraulic cylinders, the both ends of 3 piston rod of hydraulic cylinder respectively with piston 11 and piston 21
Connection can drive piston 11 and piston 21 mobile in the same direction.Material cylinder 1 is located at working chamber A and 2, material cylinder on the left of piston 11
Working chamber C in 21 left side of piston is connected to by pipeline I；Material cylinder 1 is located at working chamber B and 2, material cylinder on the right side of piston 11
Working chamber D in 21 right side of piston is connected to by pipeline II.Pipeline I connects feed-inputing branched pipe I 9 and discharging branch pipe I 8, and pipeline II connects
Connect feed-inputing branched pipe II 5 and discharging branch pipe II 4；Divide on feed-inputing branched pipe I 9, feed-inputing branched pipe II 5, discharging branch pipe I 8 and discharging branch pipe II 4
It She You not check valve 52, check valve 51, check valve 42 and check valve 41.Feed-inputing branched pipe I 9, feed-inputing branched pipe II 5 are led with charging respectively
Pipe 7 is connected to；Discharging branch pipe I 8 and discharging branch pipe II 4 are connected to discharging supervisor 6 respectively.
As shown in Figure 1, the present invention has 4 working chambers, wherein working chamber A, working chamber C duty cycle are consistent, working chamber B
It is consistent with the duty cycle of working chamber D, therefore, working chamber A, working chamber C are connected by pipeline I, work is connected by pipeline II
Chamber B and working chamber D.When the piston rod of hydraulic cylinder 3 moves right, working chamber A, working chamber C volume increase, formed negative pressure into
Material；Working chamber B and working chamber D are squeezed, and pressure increases, discharging.When the piston rod of hydraulic cylinder 3 is moved to the left, work
Chamber A, working chamber C are squeezed, and pressure increases, discharging；Working chamber B and working chamber D volume increase, and form negative pressure, charging.Work
Chamber A, working chamber C only need to be arranged one group of one-way control valve after linking together, working chamber B is also only needed after connecting with working chamber D
One group of one-way control valve is set.The plunger pump of one group of one-way control valve of setting, control are required to relative to existing each working chamber
System processed greatly simplifies.Therefore, the invention patent enormously simplifies the topology layout of the outer pipeline of slush pump, reduces the list of half
To valve quantity, so that live operation expense sharp fall, reliability has obtained effective promotion, while reducing the manufacturing
Cost.The present invention reduces the quantity of pipeline and one-way control valve；Reduce consumptive material, reduce manufacturing cost, greatly improves
Working efficiency.Its control method is simple and reliable, enormously simplifies system structure, reduces manufacturing cost, reduce the source of trouble and
Operation expense.
