Abstract
An electric-powered lubricator according to one aspect of the present disclosure includes a motor, a drive circuit, a pump, a drive switch, a selection switch, and a control circuit. The selection switch is manually operated by a user to select a first mode or a second mode. The first mode and the second mode are operation modes of the electric-powered lubricator, the first mode associates an operation amount of the drive switch with a rotational speed in a first relationship, and the second mode associates the operation amount of the drive switch with the rotational speed in a second relationship different from the first relationship.
Claims12
An electric-powered lubricator comprising:
- a motor configured to generate a driving force;
- a drive circuit configured to drive the motor;
- a pump including a dispensing port configured to dispense a lubricant, and configured to dispense the lubricant from the dispensing port at a speed corresponding to a rotational speed of the motor by the driving force generated by the motor;
- a drive switch configured to be manually operated by a user to drive the motor;
- a selection switch configured to be manually operated by the user to select a first mode or a second mode, the first mode and the second mode each being an operation mode of the electric-powered lubricator, the first mode associating an operation amount of the drive switch with the rotational speed in a first relationship, the second mode associating the operation amount with the rotational speed in a second relationship different from the first relationship, a variable speed range in the first relationship being wider than a variable speed range in the second relationship, and the variable speed range being defined as a range where the rotational speed changes according to the operation amount;
- and
- a control circuit configured to control the motor through the drive circuit based on (i) a actual operation amount of the drive switch manually operated and (ii) the first mode or the second mode selected through the selection switch.
A method of controlling dispensing of a lubricant from an electric-powered lubricator, the method comprising:
- setting a first mode or a second mode as an operation mode of the electric-powered lubricator based on manual operation of a selection switch of the electric-powered lubricator by a user, the first mode associating an operation amount of a drive switch of the electric-powered lubricator with a rotational speed of a motor in a first relationship, the motor being configured to drive a pump of the electric-powered lubricator, the second mode associating the operation amount with the rotational speed in a second relationship different from the first relationship, a variable speed range in the first relationship being wider than a variable speed range in the second relationship, the variable speed range being defined as a range where the rotational speed changes according to the operation amount;
- and
- controlling the motor based on (i) an actual operation amount of the drive switch and (ii) the operation mode set through the selection switch based on manual operation of the drive switch by the user.
