Roller box 16 and 11 this hard metal material of crankcase have certain flexibility, can to carrying out error compensation on the two fitting surface,
Due to the error of machining accuracy, two fitting surfaces be easy to cause oil leak, pass through the oil suction of 4 plate of cardboard there may be flat situation
Effect and flexible material, can make up the out-of-flatness of fitting surface.
As shown in Fig. 2, also set up tank filler sleeve 113 on crankcase 11, after the rear end of crankcase 11 is combined with by sealing ring
Lid 118 sets drain oil 114 on rear cover 118, and fuel door 115 is threaded on tank filler sleeve 113, and screw thread connects on drain oil 114
It is connected on 116 rear cover 118 of plug cock and is provided with oil ga(u)ge observation window 117.In order to reduce the friction between crank rod 13 and plunger rod 19
And temperature rise, lubricating oil can be added in the inside of crankcase 11, it can be internal using tank filler sleeve 113 and drain oil 114
The lubricant level in portion is controlled, and passes through plug cock 116, fuel door 115 and rear cover 118 so that the inside shape of crankcase 11
Into sealing space, the leakage of lubricating oil can be reduced at this time.Due to that can not be observed in confined space, so increasing oil ga(u)ge observation window
117, so as to observe internal oil level, convenient for holding the amount refueled.
As shown in fig. 6, leaving headroom 3 between cylinder body 22 and crankcase 11, plunger rod 19 was partially exposed at gas sky
Between 3 positions.During plunger rod 19 is moved forward and backward by the driving of crank rod 13, due to the relation of friction, 19 meeting of plunger rod
Fever, so by the way that headroom 3 will be reserved between cylinder body 22 and crankcase 11, and plunger rod 19 is allowed to be partially exposed at gas
On the position in space 3, by external air flow, to take away the heat on plunger rod 19, so as to reduce the temperature of plunger rod 19
Degree.
As shown in fig. 7, pump head component 2 includes water-logged base 21, cylinder body 22 and effluent seat 23, cylinder body 22 is fixed on water-logged base 21
Between effluent seat 23, multiple passages 221 are arranged side by side in cylinder body 22, a list is installed at the both ends of each passage 221 respectively
To valve 24,111 face of one of opening and plunger mounting hole of passage 221.Passage 221, which mainly supplies water, to be flowed through, and water can be with
It is diverted in each passage 221 from water-logged base 21 by cylinder body 22, then is gone out by effluent seat 23, and played according to check valve 24
Current are moved by the driving of plunger rod 19 toward a direction, play the non-return effect of current.
As shown in fig. 7, multiple 231, gas tanks 232 of effluent switch, pressure gauge 233 are connected on effluent seat 23 and is adjusted
Pressure valve 234.It connects and controls convenient for water outlet, gas tank 232 can be used for compensating inside water pressure, and pressure gauge 233 is displayed for
Inside water pressure changes, and pressure regulator valve 234 can adjust inside water pressure.
Driving principle：13 both ends of crank rod are mounted on by bearing on bearing mounting hole 112, and at bearing mounting hole 112
In on same axis so that crank rod 13 rotates on the same axis, and 13 Comparision of crank rod is stablized, more enough promotion plunger rods
19 movements, in order to enable compact overall structure, convenient for high efficiency of transmission power, employs 17 engaged transmission of gear wheel 15 and pinion gear
Mode carry out, /V and protection to the installation of large and small gear 17 are played in and the installation of gear-box 16, and gear wheel 15 drives song
Axostylus axostyle 13, pinion gear 17 connect input shaft 18, and input shaft 18 connects external motor, by gear drive, avoids belt pulley and beat
The phenomenon that sliding, overall structure compact appearance, smaller by external disturbance, movement environment is more reliable and more stable.After power input, profit
After with gear wheel 15 crank rod 13 being driven to rotate, plunger rod 19 moves back and forth so that 2 efficient water outlet of pump head component.
As shown in figure 8, plunger rod 19 sets three, and elastic carry out successively.Water inlet based on water-logged base 21
In centre, so while based on regular draw water, it is also necessary to water inlet position be coordinated to carry out current deflecting, when intermediate column
Stopper rod 19 retreats, and the plunger rod 19 of both sides advances, at this point, flow dynamic is flowed from centre to both sides, then goes out from effluent seat 23
It goes.
Embodiment 2：
A kind of plunger connection pump, in above-described embodiment, difference lies in as shown in figure 9, plunger rod 19 sets three, and intermediate
When plunger rod 19 retreats, 19 advanced in unison of plunger rod of both sides.It according to fluid dynamics, thus designs, plunger rod 19 has
The movement of rule, current are gone out, this process, water movement has after the entrance of water-logged base 21 by cylinder body 22, then from effluent seat 23
Rule, the impact to cylinder body 22 are regular, the impacts of a stage single order section, so as to improve the efficiency of current conveying, are subtracted
Few internal fluid convection current impact is to moving loss of energy, so as to efficiently send water.
