Description

A kind of metering pump
Technical field
The utility model relates to pump, is specially a kind of metering pump.
Background technique
In producing the Hydrogenated rosin process, need to use metering pump.The pump head parts are one of vitals of metering pump, according to pumped fluid characteristics and applying working condition requirement, this pump head structure is divided into plunger type and diaphragm type, and existing ram type pump head member mainly is comprised of liquid cylinder, plunger, suction and expulsion valve and filler etc., causes easily the filler seepage.The result of seepage so that metering is inaccurate, damages material, befouling environment on the one hand on the other hand.In order to reduce its leakage loss, certainly will to lengthen filler chamber's length increasing the quantity of filler, or add the blue pressure of kilocalorie, so not only so that resistance increases, and accelerated wearing and tearing, make on the contrary and reveal aggravation.Therefore, in actual applications, usually to stipulate the scope of amount of leakage, make it neither excessive, can not be too small, thus the purpose that realizes prolonging filler working life and protection pump.However, in practical operation, should be difficult to grasp and realize, and because will check at any time and adjust the amount of leakage of pump, increase workload, strengthen cost.
The model utility content
The technical problem that the utility model solves is to provide a kind of metering pump, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of metering pump, comprise pump head, described pump head comprises plunger, filler, liquid cylinder, and described liquid cylinder links to each other with bay cover by the fluid cylinder carriage, is provided with described filler between described plunger and the liquid cylinder, the end of described plunger is provided with liquid retaining ring, the afterbody of described plunger is fixed by banking stop and pipe, and described pipe is fixed with pressing plate outward, and described banking stop is provided with valve ball, described valve ball is fixed on the valve seat, and described valve ball is provided with valve pocket outward.
In the utility model, described bay cover is provided with funnel.
Beneficial effect
The utility model is simple in structure, processing ease and favorable sealing property, long service life.
Description of drawings
Fig. 1 is a kind of pump head structure schematic representation of metering pump.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of pump head structure schematic representation of metering pump, a kind of metering pump, comprise pump head, described pump head comprises plunger 8, filler, liquid cylinder, described liquid cylinder links to each other with bay cover 6 by the fluid cylinder carriage, be provided with described filler between described plunger 8 and the liquid cylinder, the end of described plunger is provided with liquid retaining ring 9, the afterbody of described plunger 8 is fixing with pipe 1 by banking stop 3, is fixed with pressing plate 2 outside the described pipe 1, and described banking stop 3 is provided with valve ball 4, described valve ball is fixed on the valve seat, the described valve ball 4 outer valve pockets 5 that are provided with.
In the utility model, described bay cover 6 is provided with funnel 7.
Along with plunger to-and-fro motion in hydraulic cylinder, suction, valve group alternately open and close, liquid is constantly discharged and is sucked, pump forms negative pressure, so that suction valve is opened in the pump head sap cavity in the process that sucks, liquid flows into the cylinder chamber, in discharging stroke, the movement of plunger has increased pressure at liquid, so that liquid is discharged.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model; the technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims (2)

1. metering pump, comprise pump head, described pump head comprises plunger, filler, liquid cylinder, and described liquid cylinder links to each other with bay cover by the fluid cylinder carriage, be provided with described filler between described plunger and the liquid cylinder, the end of described plunger is provided with liquid retaining ring, it is characterized in that, the afterbody of described plunger is fixed by banking stop and pipe, described pipe is fixed with pressing plate outward, described banking stop is provided with valve ball, and described valve ball is fixed on the valve seat, and described valve ball is provided with valve pocket outward.
2. a kind of metering pump according to claim 1 is characterized in that, described bay cover is provided with funnel.
