Description

A kind of stuff-discharging and pumping device
Technical field
The utility model belongs to plasma discharge conveying technology field, is specifically related to a kind of stuff-discharging and pumping device.
Background technique
Aspect stuff-discharging and pumping, traditional volume pumping installations is divided into two kinds for sleeping in, vertical.
Horizontal volume pumping installations is referring to Fig. 1, because of condition restriction such as the volume of mechanically operated power end, weight, normally adopt horizontal pump slurry structure, by the drive unit of bent axle (handle) linkage mechanism 5, move reciprocatingly through guiding cross joint 6 drives in the horizontal slurry pumps with ore pulp, mud directly contact metal plunger or rubber piston 7.Because the medium that is pumped often has stronger tempering property, proportion is bigger, is easy to sedimentation in the pumping chamber, gently descends turbid distribution formations in, to formation eccentric wears such as plunger and Sealing, pistons, produces bigger lateral stress; While is for the equipment of big plunger, long stroke, horizontally-mounted plunger, piston itself just have bigger deadweight, coaxality during to-and-fro motion, straightness accuracy are difficult to guarantee, in the to-and-fro motion of quick, high frequency time, be easy to generate serious eccentric wear, the cooperation that damages kinematic pair greatly makes its inefficacy, make the lost of life of Sealing, piston, plunger, influence the running rate of equipment, increase the operating cost of equipment, also increased the workload of plant maintenance simultaneously.This equipment is to the bad adaptability of slip, and the slag slurry for tempering property of height almost can't adapt to especially.Along with the requirement proposition of high pump pressure, big stroke, big flow, traditional horizontal pumping equipment has been difficult to adapt to the requirement of production.
Vertical volume pumping installations is referring to Fig. 2, this device normally adopts in pairs and arranges, drive the plunger or the piston 7 of double vertical slurry pump by double vertical hydraulic jack 2, the cylinder chamber of two vertical cylinders 2 is coupled to each other with oil pipe 3, when an oil cylinder moved downward, the another oil cylinder then moved upward, thereby promoted pump slurry of two plungers, inhale slurry for one, form the action of single positive displacement pump slurry.Drive power plant that the double vertical oil cylinder comes and goes the double-action campaign and be by hydraulic-pressure pump 9 from fuel tank 10 pump oil, finish through electro-hydraulic reversing valve 8.The defective of this device: one is two oil cylinders to be mutually 90 ° relation operation, and output medium has dead (breaking) point of flow, and it is bigger to fluctuate; The 2nd, the electro-hydraulic reversing valve 8 long-continued commutation frequencys can not be high, generally be controlled at below 30 times/minute, the unidirectional jig frequency per minute that is each plunger should not be above 15 times, perfect condition is below 10 times, otherwise electro-hydraulic reversing valve becomes easily damaged parts, and system reliability significantly reduces, the latus rectum of electro-hydraulic reversing valve is limited simultaneously, approved product is the DN32mm latus rectum to the maximum on the market, and when hydraulic system needed big flow, high jig frequency, this device surface was faced danger or disaster with the hardware bottleneck of going beyond.And hydraulic-pressure pump also is one of restraining factors, hydraulic-pressure pump discharge capacity on the market is 260ml/ usually to the maximum changes, when system needs big flow, it will be many parallels connection of pumps fuel feeding, then the efficient of system obviously reduces, and can not adapt to high frequency time commutation, otherwise the hydraulic shock that produces during the high frequency time commutation will cause the quick damage of oil hydraulic pump.
This shows, be subjected to the hydraulic element condition restriction, traditional vertical volume pumping installations is used under the working condition of small flow, little pressure head usually, to the operating mode of high pump pressure, big flow, does not promptly have Economy, does not also have reliability, is difficult to use.
The model utility content
The purpose of this utility model is to provide a kind of, long service life strong to slip and adaptability for working condition, is easy to safeguard, maintenance, improve the pumping equipment running rate, big pumping capacity, high efficiency stuff-discharging and pumping device are arranged.
The technological scheme that realizes the utility model purpose is as follows:
Stuff-discharging and pumping device of the present utility model: comprise driving mechanism and vertical slurry pump, between driving mechanism and vertical slurry pump, be provided with power transmission mechanism, described power transmission mechanism comprises at least one group of hydraulic jack group of being made up of horizontal hydraulic oil cylinder and vertical hydraulic oil cylinder, wherein the piston rod of the horizontal hydraulic oil cylinder in the power transmission mechanism is connected with driving mechanism, and the piston rod of vertical hydraulic oil cylinder is connected with vertical slurry pump; The rod chamber of described horizontal hydraulic oil cylinder, rodless cavity are communicated with rod chamber, the rodless cavity of vertical hydraulic oil cylinder by oil pipe respectively, be provided with hydraulic pressure and mend discharge equipment between the oil pipe of rod chamber that connects horizontal hydraulic oil cylinder and vertical hydraulic oil cylinder and rodless cavity.
Described driving mechanism is bent axle (handle) linkage mechanism that links to each other with power, the connecting rod of bent axle (handle) linkage mechanism is connected with the piston rod of horizontal hydraulic oil cylinder by guiding cross joint, and the quantity of bent axle (handle) connecting rod is identical with the hydraulic jack group number of described power transmission mechanism.
Working principle:
Bent axle (handle) linkage mechanism by transmission system by motivational drives such as motor or diesel engines, rotatablely moving of power changed into the to-and-fro motion of mechanism rod through bent axle (handle), thereby promote the reciprocating motion of the pistons of horizontal oil cylinder, the horizontal hydraulic oil cylinder is given the vertical hydraulic oil cylinder by oil pipe with transmission of power, is moved up and down by the plunger (or piston) of the vertical slurry pump of vertical hydraulic hydraulic oil cylinder driving.Hydraulic pressure mend that discharge equipment is used to regulate and balance rod chamber oil pipe and rodless cavity oil pipe between pressure, the proper functioning of assurance device.
The utility model device, owing to adopted the hydraulic jack group of forming by a horizontal hydraulic oil cylinder and vertical hydraulic oil cylinder, the horizontal drive structure can be transformed into from the Vertical direction outputting power from the substantially horizontal outputting power, to adapt to the working method of vertical slurry pump.The utility model device combines the advantage that has horizontal and vertical two kinds of slurry pumps now, overcome their shortcoming: having solved on the one hand existing vertical volume pumping installations can not supporting horizontal drive structure, the deficiency that can only use under the working condition of small flow, little pressure head; Solved the horizontal slurry pump that adopts the horizontal drive structure on the other hand again, plunger (or piston) is easy to wear, the lost of life, the running rate of equipment is not high, the operating cost height, the Maintenance and Repair workload is big, to the problem of the bad adaptability of slip, can satisfy the requirement of high pump pressure, big stroke, big flow.
The utility model is described in further detail below in conjunction with accompanying drawing.
