Detailed Description
In order to highlight the objects, technical solutions and advantages of the present invention, the present invention will be further described with reference to the following embodiments, examples of which are provided by way of illustration rather than limitation of the present invention. The technical solution of the present invention is not limited to the following specific embodiments, but also includes any combination between the specific embodiments.
The utility model provides a fluid conveying control device, which comprises a fluid storage unit and a conveying unit used for conveying the fluid in the fluid storage unit to a fluid using end; the delivery unit is any useful device that can deliver a low-level fluid (e.g., a water source) to a fluid-using end, such as water, and is preferably a pump;
a pressure sensing unit is arranged on a pipeline between the conveying unit and the fluid using end and used for monitoring the pressure in the fluid conveying pipeline; the fluid delivery control device further comprises a control unit, which is preferably a PLC, for controlling the opening and closing of the delivery unit according to the signal transmitted from the pressure sensing unit. The pressure sensing unit transmits a monitored pressure signal to the control unit, the control unit compares the received pressure signal with a set pressure value, when the pressure in the pipeline detected by the pressure sensing unit is smaller than the set pressure value, the control unit starts the conveying unit so as to convey the fluid to a fluid using end such as water, and when the pressure in the pipeline detected by the pressure sensing unit reaches the set pressure value, the control unit closes the conveying unit so as to stop conveying the fluid to the fluid using end such as water.
In the above fluid transport control device, as a preferred embodiment, a check valve is provided between the transport unit and the fluid using end, and the check valve is provided to prevent the fluid such as water from flowing back, so as to prevent the pressure in the pipe from being too low due to the water flowing back, and the control unit makes an erroneous judgment to start the transport unit to transport the fluid to the fluid using end.
In the fluid delivery control device, as a preferred embodiment, the fluid using end is provided with an outlet valve, when fluid such as water is required to be used, the outlet valve is opened, the pressure in the pipeline can be lowered by opening the outlet valve, when the pressure in the pipeline is smaller than a set pressure value, the control unit starts the delivery unit to deliver the fluid to the fluid using end, when the fluid such as water is not required to be used, the outlet valve is closed, after the outlet valve is closed, the pressure in the pipeline rises because the delivery unit such as a pump is still running, and when the pressure reaches the set pressure, the control unit automatically closes the power supply of the delivery unit such as a pump according to the judgment of a pressure set value and a signal of a pressure monitoring sensor, so that the purpose of stopping the pump and stopping the water.
In the above fluid delivery control device, as a preferred embodiment, the pressure sensing unit is provided on a pipe between the check valve and the outlet valve.
The utility model discloses except being applicable to water conveying system, also can be used to other fluid systems.
Specifically, the utility model provides a fluid transport controlling means, see fig. 1, fluid transport controlling means is including the pond 1, delivery pump 2 and the end of using water that are used for holding fluid such as water, and the water in low-order water source such as pond 1 is carried to the end of using water through delivery pump 2, is equipped with pressure monitoring sensor 3 between delivery pump 2 to the end of using water, and pressure monitoring sensor 3 is used for monitoring the pressure of pipeline between delivery pump 2 and the end of using water.
When water is needed, the outlet valve 6 of the water is opened (namely, a valve at the water end is used), the pressure in the water pipeline is lowered, when the pressure in the water pipeline is lower than the set pressure, the pressure monitoring sensor 3 transmits a signal to the controller in the control cabinet 4, the control cabinet 4 automatically opens the pump power switch of the delivery pump 2, and then the delivery pump 2 starts delivery, so that the water is delivered to the water end, and the purpose of starting the pump for water is achieved.
When the water consumption is stopped, the outlet valve 6 is closed, at the moment, the pressure in the water conveying pipeline can rise due to the fact that the conveying pump 2 is still in the running state, when the set pressure is reached, the control cabinet 4 automatically closes the power switch of the conveying pump according to the pressure set value and the signal judgment sent by the pressure monitoring sensor, and therefore the water conveying to the water consumption end is stopped, and the purpose of stopping the pump and stopping the water supply is achieved.
As a preferred embodiment, a one-way valve 5 for preventing water backflow is arranged between the delivery pump 2 and the outlet valve 6, and the one-way valve enables water to be delivered to the outlet valve 6 from the delivery pump 2 but not to flow to the delivery pump 2 from the one-way valve 5, so that a certain pressure is kept in the pipeline after the delivery pump 2 is closed, and the phenomenon that the pressure in the pipeline is too low due to water backflow and the delivery pump 2 is started to supply water due to misjudgment of the control cabinet 4 is avoided. Preferably, the pressure monitoring sensor 3 is arranged on the conduit between the one-way valve 5 and the outlet valve 6, and when the outlet valve is closed, the pressure between the one-way valve 5 and the outlet valve 6 increases, so that the signal of the pressure monitoring sensor 3 indicates that the delivery pump 2 is closed.
