Abstract
A plural component system includes a first pump configured to pump a first constituent material to an applicator and a second pump configured to pump a second constituent material to the applicator. A controller is operatively connected to the first pump and the second pump to control operation of the first pump and the second pump to pump the first and second constituent materials to the applicator at a desired ratio.
Claims30
A plural component system comprising:
- a first pump for pumping a first constituent material, the first pump having a first electric motor;
- a second pump for pumping a second constituent material, the second pump having a second electric motor;
- an applicator configured to receive the first constituent material and the second constituent material and emit a plural component material formed by mixing of the first constituent material and the second constituent material;
- and
- a controller operatively connected to the first electric motor to control pumping by the first pump and to the second electric motor to control pumping by the second pump, the controller configured to:
- receive first parameter information regarding a first output of the first pump and second parameter information regarding a second output of the second pump;
- designate a pump status to the first pump and the second pump such that one of the first pump and the second pump is designated as a lead pump and designates an other one of the first pump and the second pump is designated as a follower pump, the controller configured to designate the pump status based on:
- a displacement ratio between the first pump and the second pump, the controller designating a larger output one of the first pump and the second pump as the lead pump and designating a smaller output one of the first pump and the second pump as the follower pump if the displacement ratio is other than 1:1;
- and
- the first parameter information and the second parameter information if the displacement ratio is 1:1;
- and
- control operation of the follower pump such that a displacement speed of a fluid displacer of the follower pump is based on a displacement speed of a fluid displacer of the lead pump.

A plural component system comprising:
- a first pump for pumping a first constituent material, the first pump having a first electric motor;
- a second pump for pumping a second constituent material, the second pump having a second electric motor;
- an applicator configured to receive the first constituent material and the second constituent material and emit a plural component material formed by mixing of the first constituent material and the second constituent material;
- and
- a controller operatively connected to the first electric motor to control pumping by the first pump and to the second electric motor to control pumping by the second pump, the controller configured to:
- receive first parameter information regarding a first output of the first pump and second parameter information regarding a second output of the second pump;
- designate a pump status to the first pump and the second pump based on a displacement ratio between the first pump and the second pump, the controller configured to:
- designate a larger output one of the first pump and the second pump as a lead pump and designate a smaller output one of the first pump and the second pump as a follower pump if the displacement ratio is other than 1:1;
- and
- designate one of the first pump and the second pump as the lead pump and designate the other one of the first pump and the second pump as the follower pump based on the first parameter information and the second parameter information if the displacement ratio is 1:1;
- control operation of the follower pump such that a displacement speed of a fluid displacer of the follower pump is based on a displacement speed of a fluid displacer of the lead pump;
- and
- redesignate the other one of the first pump and the second pump as the lead pump and the one of the first pump and the second pump as the follower pump based on the first parameter information and the second parameter information indicating that an output parameter of the other one of the first pump and the second pump has overtaken an output parameter of the one of the first pump and the second pump.

A plural component system comprising:
- a first pump for pumping a first constituent material, the first pump having a first electric motor;
- a second pump for pumping a second constituent material, the second pump having a second electric motor;
- an applicator configured to receive the first constituent material and the second constituent material and emit a plural component material formed by mixing of the first constituent material and the second constituent material;
- a user interface configured to receive an output setting from a user, the output setting providing a target output parameter for the plural component material;
- and
- a controller operatively connected to the first electric motor to control pumping by the first pump and to the second electric motor to control pumping by the second pump, the controller configured to:
- receive first pump parameter information regarding the first pump;
- receive second pump parameter information regarding the second pump;
- control operation of the first pump and the second pump based on the output setting, the first pump parameter information, and the second pump parameter information such that the first pump and the second pump output the first constituent material and the second constituent material at a desired ratio;
- designate a pump status to the first pump and the second pump such that a larger output one of the first pump and the second pump is a lead pump and a smaller output one of the first pump and the second pump is a follower pump based on a displacement ratio between the first pump and the second pump being other than 1:1;
- and
- designate one of the first pump and the second pump as the lead pump and designate the other one of the first pump and the second pump as the follower pump based on the first parameter information and the second parameter information based on the displacement ratio between the first pump and the second pump being 1:1.
