In one embodiment, after the motor 20 in the invention works, the reciprocating motion of the piston rod is further realized through the mutual engagement of the copper gear and the crown gear, and after water exists in the pump shell, the piston rod further pushes the piston to push, so that the purpose of pumping water flow into the drainage tube 27 or the cooling component from the pump shell is realized;
however, in the actual use process, the tolerance exists between the pump shell and the piston, the working states of the pump shell and the piston are reciprocating motion states, and in the reciprocating motion process, once the clamping between the pump shell and the piston occurs, the motor still works, so that the motor is burnt out or the piston rod is damaged; therefore, the invention also comprises a motor control method which is used for judging the jamming between the pump shell and the piston and adjusting the speed or the movement direction of the motor based on the judging result so as to eliminate or reduce the damage of products caused by the jamming of the pump shell and the piston.
The motor control method comprises the following steps:
acquiring position parameters of the piston on the pump shell, and establishing a tolerance model of the piston;
obtaining a position deviation range of the piston based on the position parameter, and if the maximum error range is larger than a first preset value, reducing the rotating speed of the motor; if the maximum error range is larger than the second preset value, an alarm instruction is generated and sent to an alarm unit for alarm.
The position parameter of the piston on the pump shell can be obtained by embedding a distance sensor on the inner wall or inside the pump shell; and/or the pump shell is of a transparent structure, and a distance sensor is arranged outside the pump shell.
As shown in fig. 12, the tolerance model of the piston is that the cylindricity model of the piston includes a translational vector model and a rotational vector model, which expresses the translational vector model by formula (1):
expressing the rotation vector model by the formula (2):
wherein l is the length of the piston, S u Is the absolute value of the deviation on the outer diameter of the piston, S d Is the absolute value of the deviation of the outer diameter of the piston, S i Is the tolerance value of the piston; p (P) r Is the translational vector of the horizontal clearance between the piston and the pump shell, P z Is the z-axis translation vector of the piston, D r D is the rotation vector of the turning offset between the piston and the pump shell along the transverse center line z Is the z-axis rotation vector of the piston;
obtaining a position offset range of the piston based on the position parameter further includes:
calculating the position deviation range of the piston by utilizing the rotation model and combining the cylindricity model of the piston;
constructing a three-dimensional model of the pump casing and the piston, and obtaining the rotation model based on the three-dimensional model, wherein the rotation model is expressed by using a formula (3):
wherein G is the movement function requirement of the pump shell and the piston, Z m Assembling a matrix of features for the mth; w (W) m The displacement spin for the mth mounting feature, n is the number of mounting features that have an effect on end error.

wherein,,
for matrix->
Values located at the position of matrix (1, 1), matrix +.>
Is a relative global coordinate system; w (W) m(X,1) Elements in row X in the small displacement rotation matrix, (x=1, 2 …);
based on the offset Y, a positional offset of the piston is obtained, and a rotational speed of the motor or a rotational direction of the motor is determined according to an offset range of the positional offset of the piston.
After long-term use, when the micro-deviation is caused by abrasion, the rotating speed of the motor can be reduced to prolong the service life of the tooth washer, so that the situation that the piston movement frequency is too high due to too high rotating speed, and further the deviation acceleration caused by larger centrifugal force generated by high movement frequency is reduced; further deterioration of harmful factors is effectively inhibited;
when the offset has high-value offset, generating an alarm instruction, and sending the alarm instruction to a user terminal to prompt a user to send product equipment to a manufacturer for maintenance;
when the offset can reach the katon, the motor stops working, generates an alarm instruction, and sends the alarm instruction to the user terminal to prompt the user to send the product equipment to the manufacturer for maintenance.
When determining the offset Y value, there is an offset error determination of the first boundary and the second boundary, that is, the offset errors of the first boundary and the second boundary determine an error distribution interval of the offset, and to improve the data accuracy, the first boundary and the second boundary are calculated by using the following formula by using the formula (5) and the formula (6):
wherein Y1 is a first boundary, Y2 is a second boundary, when W m(X,1) Index (-1) k 、(-1) j When the value of (2) is greater than 0, W m(X,1) A first boundary and a second boundary.
Wherein,,
based on the limitation of the first boundary and the second boundary, the offset Y can be further optimized, and the accuracy of adjusting the working state of the motor is improved; the situation that the motor is controlled in an error working state due to inaccurate offset calculation is greatly reduced, and therefore the use effect and the comfort of a user are improved on the premise of protecting the safety or the service life of a product.
