Embodiment
Describe the performance that tradition is used for plunger pump with the extrusion pump of a kind of suitable underflow mass transport of the present invention of underflow mass transport in detail below in conjunction with accompanying drawing, advantage of the present invention like this will become apparent and understanding easily.
Consult Fig. 1 as can be known: the working procedure of traditional plunger pump is: drive the speed reducer running by belt transmission behind the starting electrical machinery, and reciprocating through eccentric wheel 1-9 drivening rod 1-10, slide block 1-8 and plunger rod 1-7.
Charging valve block 1-2 opens during process, and discharging valve block 1-5 closes, and material enters in the charging valve seat 1-13 chamber by charging cylinder body 1-1 and plunger case 1-14, finishes fill process.
Charging valve block 1-2 closes during backhaul, and discharging valve block 1-5 opens, and material is gradually squeezed outside the discharging cylinder body 1-4 by discharging valve seat 1-3, finishes the discharging process.Entering and course of conveying of material finished in to-and-fro motion so again and again.
Because plunger rod 1-7 links to each other with charging valve block 1-2, material enters the charging valve seat by plunger case 1-14 when process
In the chamber, plunger rod sealing gasket 1-12 is in negative pressure state, and fill process can not cause material from leakage.But discharging valve block 1-5 communicates with the plunger rod sealing part when backhaul, and the pressure of material outlet pressure and plunger rod sealing part is suitable, and up to about 0.3-1.0Mpa, material often leaks unavoidable from sealing part 1-12.Solution is termination of pumping often, and to sealing constantly in addition fastening or changing, the special messenger serves.Transfer efficiency is low, and repair density is big, and the material of leakage is contaminated, and site environment is poor, can not satisfy production requirement with being good at.
Consult Fig. 2 as can be known: the extrusion pump of a kind of suitable underflow mass transport of the present invention, it comprises discharging cylinder body 2-4, charging cylinder body 2-1, support 2-11, it is characterized in that the top that described discharging cylinder body 2-4 is positioned at the end of charging cylinder body 2-1 communicates with charging cylinder body 2-1, discharging valve seat 2-3 is arranged in the discharging cylinder body 2-4, discharging valve block 2-2 is arranged on the discharging valve seat 2-3, and there is material outlet II discharging cylinder body 2-4 upper end; In the described charging cylinder body 2-1 charging valve seat 2-13 and plunger case 2-14 are arranged, charging valve block 2-5 is arranged between charging valve seat 2-13 and the plunger case 2-14, plunger case 2-14 communicates with material inlet I on the charging cylinder body 2-1; In the described support 2-11 plunger rod 2-7 is arranged, plunger rod 2-7 attachment post plug cylinder 2-14, support 2-11 has connecting rod 2-10 outward, and connecting rod 2-10 is connected with plunger rod 2-7, between described support 2-11 and the charging cylinder body 2-1 sealing gasket 2-12 is arranged.Described connecting rod 2-10 is connected with eccentric wheel 2-9, and the end of described charging cylinder body 2-1 has guiding tube 2-16, and communicates with discharging cylinder body 2-4 by guiding tube 2-16.
The working procedure of the extrusion pump of a kind of suitable underflow mass transport of the present invention is: drive the speed reducer running by belt transmission behind the starting electrical machinery, and reciprocating through eccentric wheel 2-9 drivening rod 2-10 and plunger rod 2-7.
Discharging valve block 2-2 opens during process, and charging valve block 2-5 closes, and material enters in the discharging valve seat 2-3 chamber by charging cylinder body 2-1 and plunger case 2-14 and is discharged from, and finishes material conveying process.
Discharging valve block 2-2 closes when backhaul, and charging valve block 2-5 opens, and material enters in the charging cylinder body 2-1 by charging valve seat 2-13, finishes fill process.Entering and course of conveying of material finished in to-and-fro motion so again and again.
Because plunger rod 2-7 links to each other with charging valve block 2-5, material enters in the discharging valve seat 2-3 chamber by charging cylinder body 2-1 and plunger case 2-14 and is discharged from during process, charging valve block 2-5 is in the state of closing all the time when process, plunger rod sealing part 2-12 is in passive state, thereby the discharge process can not cause into material from leakage.Charging valve block 2-5 opens and communicates with plunger rod sealing part 2-12 when backhaul, and plunger rod sealing part 2-12 is in negative pressure state, can not cause material from leakage.
Compare with traditional plunger pump, no matter the extrusion pump of our company's exploitation is process or backhaul, discharge or charging, and the plunger rod sealing part is in not have all the time presses or negative pressure state, has thoroughly solved a material from leakage difficult problem.The transfer efficiency of material significantly improves, and amount of maintenance reduces greatly, and site environment is greatly improved.
Need to prove that for these professional those skilled in the art under the situation that does not change the principle of the invention, can also make suitable change and distortion to the present invention, this belongs to protection scope of the present invention equally.
