Feature request: Adjustable-speed pumps

[macdjord]

When testing fluid systems, it would be helpful to be able to create pumps with maximum pumping speeds other than the default 12,000/s.

I therefore suggest adding a modded pump which has a GUI where the player can specify the desired maximum pumping rate. The GUI should accept the value in units per tick, per second, or per minute, and should accept non-integer values.

There exist workarounds using an inifinity pipe connected to a pump to limit its flow rate, but:

• That requires an extra pipe segment attached to the pump; it would be far more natural to set the rate on the pump itself
• The infinity pipe segment acts as an infinite fluid source or sink; there is no way to rate-limit a pump in the middle of a fluid system.
• The workaround is restricted to incrementing the flow rate in multiples of 60 units/s up to a maximum of 6000 u/s; there is no way to, e.g., limit a pump to 30 u/s or 10,000 u/s.

Factorio 1.1 will let you set infinity pipes to constantly add or remove a certain amount of liquid to/from themselves. This lets you test input or output rates, but does not let you rate-limit in the middle of a system. I will see about making it so pumps can have their speed changed at runtime for that usecase.

v1.6.0 was released yesterday, and included the new super pumps with an adjustable pumping speed! See the forum thread you linked for more information.
