Abstract
The invention discloses a damping type plunger pump which adopts a circular-ring-shaped linear motor drive technology. The damping type plunger pump comprises a special circular-ring-shaped plunger piston which can be driven by a coil surrounded by the special circular-ring-shaped plunger piston to rotate clockwise / anticlockwise in the circumferential direction; a water inlet chamber and a water outlet chamber are integrated, so that system problems such as vibration generated when an existing single-plunger-piston double-cylinder pump moves the plunger piston left and right are reduced; moreover, the plunger piston is embedded into a circular-arc-type drive coil, so that the plunger piston and the drive coil are supported by a copper oil-containing bearing; a water inlet chamber assembly and a water outlet chamber assembly are integrated and are arranged in a centrosymmetric mode, so that high-pressure outlet water with pulsation is mixed in the water outlet chamber or a high-pressure gas chamber is added, and therefore, pulsation of final outlet water is reduced.
Description
Technical field
The invention belongs to agricultural spraying equipment technical field, refers in particular to a kind of shock-absorbing type plunger displacement pump.
Background technology
At present, the driving method of agricultural single plunger twin cylinder pump mostly is miniature gasoline engine, and type of drive is by small gasoline
Machine drives plunger bilateral reciprocation by reduction gear box；Because the structure of pump is symmetrical left and right arrangement, so left in plunger
Vibration is inevitable during right reciprocating motion, and the drip chamber and intake chamber of pump splits two ends, and the pulsation phenomenon of current is also
Systemic reason.
Due to current this structure duplex plunger pump more be used on backpack ejection machine, the vibration of gasoline engine, noise is folded
Plus the vibration of pump, so make operator's labour intensity of the product larger, but due to its operating pressure height, up to 2.0-
4.0MPa, so in orchard, small area paddy fields in south china (particularly country in Southeast Asia) still has more market, customs in 2015
As shown by data, the gross annual output of the kind is sold at 2,000,000 or so.
And the multiplex membrane pump of domestic electrodynamic type sprayer at present, because of its low price, price of complete machine ability 90-100 unit, production
Condition is almost submerged access threshold and supervision, adds China's people in the countryside aging, operator is required it is extremely low, so bad city drives
The phenomenon in good city is the real picture of current equipment for plant protection rural market；Institute, university and local the allowance for purchase of agricultural machinery mechanism
Crave for grandeur and success, only study and subsidize large-scale, no one's research is suitable for southern little spraying machine type and is particularly small-size spraying machine
Product pump；Cause south China and Southeast Asian countries small-sized plant protection machinery to be gone on along and imitate the way for plagiarizing Japanese type, with day
This type is high, and nearly 10 years without innovation.Nearly 5 years power sprayes and knapsack sprayer are particularly on ten-thousand-ton train platform
In the paper of pump used research, the paper of academic research is known clearly very few, it may be said that at present small knapsack spraying machine in the country's is produced
The research that product are particularly the electronic electrolemma pump of knapsack sprayer high-pressure pump/big shaft power of high pressure is several for blank.
Therefore, the today flourished in new forms of energy battery, a kind of light-duty portable pressure is lacked on market in 2.0-
3.0MPa, new forms of energy sprayer of the discharge rate in 6-8LPM.Seen with motor-driven plunger displacement pump+48V lithiums electricity/lead electricity in the market
Come, by standard meter the pressure 3.0MPA and flow 8LPM of plunger displacement pump are calculated, then hydrodynamic(al) rate needs 3.0MPa × 8/60=400W, examines
The efficiency of the mechanical efficiency and motor of considering pump typically takes 70%, motor 500～600W of rate, and battery 48V will be in more than 60AH
Can work 2～3 hours, weight is in more than 30KG and cost is more than 2000 RMB for above configuration, is current 5.5HP gasoline
Machine adds with FST-22 plunger displacement pumps (whole machine producer price in terms of 500 yuan, discharge rate 15-20LPM, pressure 4MPa, gasoline acc power 5.5HP)
4 times；It may be said that this technical scheme is almost without market prospects, this is also current high-power electric spraying machine without the marketization
Main cause.
The content of the invention
The present invention is to drive the experience of small-sized plunger pump with the basis of, to electricity according to my 380,000 gasoline engines of company's annual production
Machine drives plunger pump portion to do substantial amounts of proving test, and a kind of annular post is devised in current configuration machine and structure
Plug, and by plurality of electromagnetic coil drive, under the premise of the current power of battery and cost；Reach basic plant protection requirement i.e. pressure
2.0MPa or so, flow 6-8LPm；Main screw lift 10kg (battery weight is separately counted), working hours more than 3 hours 48V, 60AH；Machine
Tool mechanical shock and discharge pressure pulsation are greatly reduced.
The object of the present invention is achieved like this：A kind of shock-absorbing type plunger displacement pump, including nonocclusive annular plunger, annulus
Shape plunger can carry out clockwise/counterclockwise circumferencial direction rotation in the case where the solenoid that surrounded drives, and the two of annular plunger
Individual free end is respectively fitting in two pressure chambers of cylinder body, and two pressure chambers are distributed with regard to cylinder body Central Symmetry, and cylinder body enters
Hydroecium and two pressure chambers, drip chamber and two pressure chambers are intercepted respectively by water intaking valve and outlet valve.
Preferably, the annular plunger is mounted in copper oiliness bearing, and bearing is embedded in the solenoid of same curvature
In.
Preferably, the cylinder body enters drip chamber for overall processing or separable assembled together.
Preferably, mix or be connected with plenum chamber in draining room.
Preferably, it is furnished with damping coil on the annular plunger, for being justified by circuit control realization in the end of stroke

Preferably, the outlet valve front end is equipped with the damping spring for annular plunger.
Preferably, cylindrical plunger is combined with described two pressure chambers, two free ends of annular plunger lead to respectively
Cross connecting rod connecting cylinder shape plunger.
The present invention is prominent and beneficial compared to existing technology to be had the technical effect that：
The present invention adopts circular linear electric motors actuation techniques, by specific annular plunger, can be in the line for being surrounded
Circle carries out circumferencial direction rotation (clockwise/counterclockwise) under driving；Enter drip chamber to be integrated, it is double so as to reduce current single plunger
System problems such as the vibration produced during cylinder pump side-to-side movement plunger, and plunger is embedded in circular arc type driving coil, plunger and drive
With the support of copper oiliness bearing between moving winding, enter draining being made of one of chamber assembly and be centrosymmetrically arranged, there is the height of pulsation
Extrude water to mix in draining room or plus plenum chamber, so as to reduce the pulsation of last water outlet.
