In this embodiment, the water spraying requirement data includes data such as spraying angle, water pressure and water quantity, and relevant water spraying requirement data can be input on the interaction component 41, the interaction component 41 transmits the input water spraying requirement data to the data acquirer 31, and the data acquirer 31 transmits the acquired water spraying requirement data to the data calculator 32. The data calculator 32 generates plunger displacement data from the received water spray demand data, and generates motor operation angle data from the plunger displacement data, and the data calculator 32 transmits the motor operation angle data to the output controller 33. The output controller 33 controls the motor 1 to do circular arc forward and backward alternate motion according to the received motor operation angle data, and further drives the plunger 232 to move in the pump body 231, so that water absorption and water spraying actions are realized. The control method in the embodiment can flexibly adjust the injection angle, the water pressure and the water quantity according to the water injection requirement, and improves the application efficiency.
In an embodiment of the present invention, referring again to fig. 3, generating plunger displacement data according to water injection demand data includes:
s21, obtaining a single-period water spraying volume according to water spraying demand data;
s22, acquiring the volume of the pump body;
s23, generating plunger displacement data according to the single-cycle spray water volume and the pump body volume.
In this embodiment, the single-cycle water spraying volume refers to the amount of water sprayed by the pump body 231 when the plunger 232 is pushed and pulled in the pump body 231 for one movement cycle. During the movement of the plunger 232, the water flow in the water flow channel 2311 of the pump body 231 is full, and plunger displacement data is obtained according to the volume and the single-cycle water spray volume in the pump body 231.
In an embodiment of the present invention, referring again to fig. 4, generating motor operation angle data from plunger displacement data includes:
s31, acquiring the travel distance from the center of the plunger to the outer circumference of the eccentric wheel;
s32, obtaining the eccentric distance of the eccentric wheel;
and S33, obtaining motor operation angle data according to the plunger displacement data, the travel distance and the eccentric distance.
In this embodiment, the travel distance L2 between the center of the plunger 232 and the center of the eccentric wheel 221 is first obtained, and then the eccentric distance L1 of the eccentric wheel is obtained, and the motor operation angle data θ is obtained according to the plunger displacement data X, the travel distance L2 and the eccentric distance L1. Let the center of the crank 222, the center of the connecting rod 224 and the plunger 232 travel be described in a straight line, taking one of them as a reference point:
when the reference point moves to the furthest end from the motor 1, i.e., the crank 222 rotates to the end closest to the pump body 231, the corresponding plunger 232 enters a travel distance l1+l2, i.e., the distance from the plunger 232 to the center of the output shaft of the motor 1.
When the reference point moves to the nearest end from the motor 1, i.e., the crank 222 rotates to the end farthest from the pump body 231, the corresponding plunger 232 enters the stroke distance L2-L1, i.e., the distance from the plunger 232 to the center of the output shaft of the motor 1.
When the reference point moves between the nearest end to the motor 1 and the farthest end to the motor 1, and the connecting line and the horizontal angle between the reference point and the center of the eccentric wheel 221 are θ, the horizontal distance corresponding to the eccentric distance L1 is L1 x COS θ, the vertical distance corresponding to the eccentric distance L1 is L1sin θ, and the horizontal distance corresponding to the travel distance L2 isThe corresponding plunger 232 entering travel distance at this time satisfies:
according to the actual situation, a proper value is set, and the control mechanism 3 matches corresponding parameters to control the specific stroke of the plunger 232.
In one embodiment of the present invention, the water spray demand data includes: water spray pressure demand data, water spray volume demand data, and/or water spray angle demand data.
In this embodiment, the water spray water pressure requirement data, the water spray water volume requirement data and/or the water spray angle are input on the interaction component 41, and are transmitted to the control mechanism 3 through the interaction component 41, the control mechanism 3 calculates the motor operation angle data θ according to the water spray water pressure requirement data, the water spray water volume requirement data and/or the water spray angle, and controls the motor 1 to perform circular arc forward and reverse alternate motion according to the motor operation angle data θ, so as to drive the plunger 232 to move, so that the water volume required by the target requirement, the water pressure required by the target requirement and the spray angle required by the target requirement are sprayed out through the pump body 231, thereby realizing the electronization of each function of the water pump 23, and improving the loom efficiency.
The foregoing description is only of the optional embodiments of the present invention, and is not intended to limit the scope of the invention, and all equivalent structural modifications made by the present description and accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the present invention.
