A peristaltic pump precise dosing control system includes a driver, a pump head, pipeline switching means, a metering pipeline, and a discharge pipeline. An elastic tubing is provided in the pump head, and the outlet end of the elastic tubing is connected to the pipeline switching means. The driver drives the pump head to rotate to pump the liquid in the elastic tubing to the outlet end of the elastic tubing. The driver is electrically connected to the pipeline switching means so as to be capable of controlling the pipeline switching means to switch to the output pipeline with which the outlet end of the elastic tubing is connected. The pipeline switching means is driven to switch the outlet end of the elastic tubing from a state of connection with the discharge pipeline to a state of connection with the metering pipeline.

A peristaltic pump, and related system method are provided. The peristaltic pump includes a cam shaft, first and second pinch-valve cams, first and second pinch-valve cam followers, a plunger cam, a plunger-cam follower, a tube receiver, and a spring-biased plunger. The first and second pinch-valve cams are coupled to the cam shaft. The first and second pinch-valve cam followers each engage the first and second pinch-valve cams, respectively. The plunger cam is coupled to the cam shaft. The plunger-cam follower engages the plunger cam. The tube receiver is configured to receive a tube. The spring-biased plunger is coupled to the plunger-cam follower such that the expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates pushes the plunger cam follower towards the plunger and thereby disengages the spring-biased plunger from the tube. A spring coupled to the spring-biased plunger biases the spring-biased plunger to apply the crushing force to the tube.

A system and method for automatic selection and control of pumps for well stimulation operations is disclosed. In certain embodiments, a system may comprise a pumping system comprising one or more pumping units, a fluid manifold providing fluid communication between the one or more pumping units and a wellbore, and a controller for determining a torque capability of the one or more pumping units.

A peristaltic pump and related-method are disclosed that includes a cam shaft having a plunger cam, a plunger-cam follower that engages the plunger cam of the cam shaft, a tube receiver, a spring, a plunger, a position sensor, and a processor. The tube receiver receives a tube. The spring provides a bias. The plunger is biased toward the tube by the spring and the plunger is to the plunger-cam follower, such that expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates actuates the plunger away from the tube. The position sensor determines a position of the plunger and the processor estimates fluid flow within the tube utilizing the position of the plunger.

Devices, systems, and methods for providing and operating a valve control module and valves in an assembly line grow pod are provided herein. Some embodiments include an assembly line grow pod having a plurality of fluid lines fluidly coupled between a fluid source and a fluid destination within the assembly line grow pod, a plurality of valves, each coupled to a fluid line such that fluid movement through the fluid lines is selectively controlled by the valves, and a master controller communicatively coupled to the valves. The master controller is programmed to receive information relating to fluid delivery within the assembly line grow pod, determine one or more valves to direct the fluid, determine valve parameters for each of the valves that achieve the fluid direction, and transmit one or more control signals to the valves for directing the fluid within the assembly line grow pod.

A vacuum pumping apparatus may include: a common pumping line having a plurality of pumping line inlets and a pumping line outlet, each pumping line inlet being configured to couple with an outlet of an associated plurality of vacuum processing chambers; at least one primary vacuum pump in fluid communication with the pumping line outlet to pump gas from each vacuum processing chamber; and control logic operable to control operation of the primary vacuum pump in response to an indication of an operating state of the plurality of vacuum processing chambers. In this way, the performance of the primary vacuum pump can be adjusted to match the load provided by the processing chambers and when there is an excess capacity, the performance of the primary vacuum pumps can be reduced, which can lead to significant energy savings and reduce wear on the pump.
