Pumps in TrySim are described by their maximum pressure and the flow. The maximum pressure is specified on the edit mask while the flow is defined by the drive. Up to now there are two drives: the bit pump and the word pump. The drive ‘linear mover’ that appears in the selection list is actually meant for the valve but it also functions with the pump and a pump with variable power and motor potentiometer can be simulated.
A pump is automatically connected to a (not bendable) pipe whose properties can be edited by the button extended. You should at least adjust the nominal diameter of the pipe to the actual conditions.
How to connect the ends of the pipe and which sensors can be connected to it can be read in the description of the pipe.
If you define a negative power or if you define a negative set point at the word pump by the PLC the direction of conveyance is inverted.
The pump always pumps the amount specified by the drive as far as it is possible with the adjusted maximum pressure. If the resistance of the following elements is too big only that much fluid is transported as it is possible with the maximum pressure. You can modify the maximum pressure with the help of a poke by the PLC program. Doing this enter the pressure in kPa (ca 0,01 bar) in the word of the poke, for a max. pressure of 8 bar you have to poke the value 800.
