Flange 6 is welded on the outside of 5 one end of mouth, flange 6 is equipped with the first steam coil 7, the first steam coil 7 for 3 top of cylinder
The temperature for promoting coal slurry, reduces their viscosity to be pumped, and changes and adjust pressure, 7 top of the first steam coil peace
Equipped with lid 8,8 top side of lid is equipped with escape pipe 9, discharges the gas of the first steam coil 7, the 8 top other side of lid
Relief valve 10 is installed, when pressure is more than that relief valve 10 sets pressure, pressure release is automatically turned on, guarantees that equipment pressure prevents
It is unexpected, first pressure component 11 is installed, 1 top side of device noumenon is equipped with spherical shape by connecting flange 17 inside cylinder 3
Container 18,18 upper outside of spherical container are equipped with the second steam coil 19, the second steam coil 19 reduce their viscosity with
Just it is pumped, 18 top side of spherical container is equipped with safety valve 20 close to 19 bottom end of the second steam coil, when the pressure of equipment
More than setting pressure when, safety valve 20 automatically turns on pressure release, guarantees that equipment pressure prevents accident, inside spherical container 18
Second pressure component 22 is installed.
Embodiment two has Fig. 2 to provide on the basis of example 1, and first pressure component 11 includes the first liner 12, gas
Chamber 13, the first air bag 14, charge valve 15 and sealing shroud 16,12 outside of the first liner and cylinder are equipped with air cavity 13 between 3 inside,
First air bag 14 is installed, 14 top of the first air bag is equipped with charge valve between 3 inner tip of first liner, 12 top and cylinder
15,12 Basolateral of the first liner is socketed with sealing shroud 16, and the pressure in sucking buffer is adjusted by air cavity 13 and liner 12
Power guarantees that equipment pressure prevents accident, by the first air bag 14 and charge valve 15 come accumulation of energy deposit, makes to deviate inlet pipeline
Farthest one turn sucking it is also stable.
Embodiment three is provided by Fig. 3 on the basis of example 1, and second pressure component 22 includes the second liner 23, resistance
Buddhist nun hole 24 and the second air bag 25,23 top two sides of the second liner offer damping hole 24, the installation of 23 upper outside of the second liner
There is the second air bag 25, pump discharge pressure pulsation rate reduces absorption and pooling feature by the second air bag 25.
Example IV is equipped with introduction valve, pacifies inside conveyance conduit 2 on the basis of example 1 on the outside of conveyance conduit 2
Equipped with layer of resist, the anti-backflow of introduction valve, the back pressure effect of certain pressure, layer of resist prevents conveyance conduit 2 to be corroded.
Embodiment five, on the basis of example 1,3 bottom end of cylinder are equipped with damping spring, are equipped with inside cylinder 3 anti-
Oxide layer, damping spring keep the cylinder 3 in work more stable, reduce noise, and anti oxidation layer prevents cylinder 3 to be oxidized.
Embodiment six, on the basis of example 1,18 design pressure of spherical container are 24.5MPa, due to three-throw ram pump
Pressure fluctuation is larger, so 18 volume of spherical container wants larger, convenient for playing buffering effect.
Working principle: transporting coal slurry by three-throw ram pump, guarantees the stability of pump sucking pressure medium, therefore pump must match
Set sucking, discharge buffer, when coal slurry from feed inlet 5 enter cylinder 3 inside the first liner 12 in, can be seen from pressure gauge 4
The pressure inside cylinder 3 is observed, when the coal slurry in the first liner 12 is more and more, the air in air cavity 13 is oppressed, and works as gas
When pressure value in chamber 13 reaches the setting value of relief valve 10, relief valve 10 opens pressure release, and air cavity 13 and the first liner 12 is allowed to press
Power keeps balance, and in order to keep deviation inlet pipeline farthest one to turn, sucking is also stable, and when sucting is stablized, inlet pressure is also needed
Accumulation of energy deposit allows charge valve 15 to open to inflating in the first air bag 14, and 14 gassy of the first air bag generates the first liner 12
Pressure allows coal slurry to enter in conveyance conduit 2, when coal slurry is discharged by three-throw ram pump, enters spherical container by connecting flange 17
In the second liner 23 in 18, three-throw ram pump pressure fluctuation is larger, and capacious spherical structure can effectively reduce pulsation,
The flow of absorption and pooling feature of the reduction of the outlet pressure pulsation rate of pump mainly by the air bag of buffer, pump contacts the second gas
The pressure fluctuation of capsule 25, the most of fluid contacted is absorbed by the second air bag 25, and the outlet pressure pulsation rate reduction of pump is also more,
Flow forms whirlpool in the flowing of the second air bag 25, and whirlpool passes through damping hole 24, is released, and reduces energy loss and noise, rises
To good voltage regulation result.
The utility model structure novel, is skillfully constructed, and sucking buffer can be allowed to guarantee that pump is inhaled using first pressure component
