Abstract
The utility model relates to an efficient plunger pump. The device comprises a pump body, a front end cap, a back end cap, and a rotor and a plunger assembled inside the end caps, wherein, the rotor provided with crossing plunger holes in arrangement is enclosed in the pump body via bearings. The plunger in the plunger hole of the rotor is assembled on a rotary shaft with a slide block. Both ends of the rotary shaft are assembled in the offset axle holes of the front end cap and the back end cap making use of the bearings and mechanical seal, and an external gear at the end part of the rotor is engaged with a drive gear supported by a bracket. Besides the advantages of the existing plunger pump, the utility model has the advantages of simple structure, few wearing parts, convenient maintenance, and can further improve the pump efficiency and the service life.
Description
The utility model relates to a kind of plunger pump, the efficient plunger pump of particularly a kind of energy transferring oil, gas, water mixed medium.
At present, carry the pump class of various media that many kinds are arranged, as centrifugal pump, gear pump, screw pump, reciprocating pump, vane pump etc., all can not transferring oil, gas, water mixed medium.Although it is comparatively general that existing crank drive-type reciprocating pump, screw pump are used,, influence it and apply because of there being problems such as big energy-consuming, maintenance load is big, efficient is low.The inventor once designed a kind of plunger pump at the problems referred to above, by intersecting the plunger working in reciprocating mode of assembling in rotor and the plunger hole thereof, finish the task of transferring oil, gas, water mixed medium, overcome prior art and had the low problem that waits of efficient, reached and operated steadily, improved the purpose in working life.
The purpose of this utility model provides a kind of improved efficient plunger pump, and it also has further raising pump efficiency, reduces the easily damaged parts wearing and tearing except that the advantage of the existing plunger pump of tool, is convenient to the characteristics of installing, safeguarding.
The purpose of this utility model is achieved in that this device comprises the pump housing, forward and backward end cap and assembles its rotor and plunger, the rotor that wherein is arranged with the intersection plunger hole is encapsulated in the pump housing by bearing, plunger in the rotor plunger hole is assembled in the rotating shaft that has slide block, the rotating shaft two ends utilize bearing and mechanical seal to be assembled in the biasing axis hole of forward and backward end cap, and the rotor tip external gear is meshed with the driving gearshaft of bearing bracket.
Because the utility model is improved on the basis of existing plunger pump (patent No. is 99223770.X), rotating shaft is dressed up with bearing pack in the two ends of former stationary axle, axle sleeve on the cancellation stationary axle, slide block directly is assembled in the rotating shaft or with slide block and rotating shaft is combined as a whole, so except that keeping the advantage that former plunger pump had, can also further overcome the abrading block between axle and slide block, the resistance of reducing friction improves pump efficiency.The loading and unloading of the rotating shaft after improving in addition also are easier to, and reduce easily damaged parts, are convenient to install, safeguard.The external toothing of rotor tip is easy to process, precision is high, moves more steadily, significantly reduces noise, reduces environmental pollution.This device is continuous reciprocating action when plunger is with rotor rotation, reaches the task of fed sheet of a media.Therefore, it has very strong from absorption, and volumetric efficiency can reach 100% when low pressure operation, and pump efficiency can reach 75-90% during the mesohigh operation, and be not subjected to the restriction of medium temperature, viscosity can transferring oil, gas, water mixed medium.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure schematic representation of the utility model.
Fig. 2 is a kind of structural representation of rotor.
Describe concrete structure of the present utility model in detail according to Fig. 1-2, this device comprises the pump housing 2, front cover 9, rear end cover 1, rotor 7, plunger 4, slide block 6, rotating shaft 8, driving gearshaft 12, mechanical seal 3,10, parts such as carriage 11, forward and backward logical lid 13,14.The suction port of its middle pump body 2 and exhaust port join by flange and delivery line.Motor-driven driving gearshaft 12 utilizes bearing to be bearing in carriage 11 logical lid in 13,14 the axis hole before and after having.Axially cross arrangement has the rotor 7 of plunger hole to utilize bearing and mechanical seal 3 to be encapsulated in the pump housing 2.Rotor 7 one ends are processed with external gear and are meshed with the end tooth wheel of driving gearshaft, rotating shaft 8 two ends that drive rotor 7 rotations utilize bearing and mechanical seal 10 to be assembled in the biasing axis hole of forward and backward end cap 9,1, and the quantity of rotor 7 upper prop consents can be selected 1-4 (present embodiment adopts two plunger holes) according to actual needs for use.The structure of the plunger 4 in each plunger hole is identical, and with the crossover location difference of plunger hole, the also corresponding cross arrangement of plunger 4 also is assembled in the rotating shaft 8 by square slider 6.Slide block 6 can activity set be contained in the rotating shaft 8, also slide block 6 can be arranged in the rotating shaft 8, and slide block 6 rotating shafts 8 are combined as a whole.For preventing plunger 4 inner wall abrasion, be fixed with pad on it.The working surface that this pad contacts with slide block 6 is easy to processing, improves its surface flatness, helps reducing the surface friction drag of slide block 6.The specification of the rotating ring of used mechanical seal 3,10 and stationary ring is determined according to actual needs in this device.
During use, the driving gearshaft 12 of this device rotates, the external gear of its end tooth wheel drive rotor 7, rotor 7 rotates when driving plunger 48 rotations around the shaft that are assembled in the plunger hole, along the to-and-fro motion of plunger hole axial direction, plunger 4 is done to inhale, is discharged into the double action work, finishes the task of carrying various media.
