In the figure: 1-a water pump; 2-a front end sensor and a mechanical pressure gauge; 3-rear sensor and mechanical pressure gauge.
The specific implementation mode is as follows:
in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described below with reference to specific embodiments shown in the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the structures and/or process steps that are closely related to the solution according to the invention are shown in the drawings, while other details that are not relevant to the invention are omitted.
As shown in fig. 1, the following technical solutions are adopted in the present embodiment: it includes water pump 1, front end sensor and mechanical pressure gauge 2, rear end sensor and mechanical pressure gauge 3, control system, water pump 1 installs at the middle part of pipeline, oil pump front end sensor and mechanical pressure gauge 2 are installed to the end of intaking of pipeline, rear end sensor and mechanical pressure gauge 3 are installed to the rear end of pipeline, front end sensor and mechanical pressure gauge 2, rear end sensor and mechanical pressure gauge 3 and control system's input electric connection, control system's output is connected with water pump 1 electricity.
Further, the control system is a PLC control system.
The embodiment comprises mechanical pressure gauges (2), pressure sensors (2), a PLC control system and a control circuit. The mechanical pressure meter and the pressure sensor are arranged on the water outlet pipe and the water inlet pipe, and the front and back water outlet and water inlet pressure meter sensors, the water pump motor unit and the PLC control system are connected together through a control circuit.
The working principle of the embodiment is as follows: the pressure sensitivity of the pressure sensor, the upper pressure limit and the lower line pressure of the mechanical pressure gauge are used for controlling the water inlet pressure and the water outlet pressure of the secondary water supply equipment to be monitored in real time, and the PLC control system identifies whether the pressure exceeds or is lower than a set value or not and controls the water pump unit to be switched on and off.
The workflow of this embodiment: the installed pressure gauge and the installed sensor transmit the current pressure value in real time, the required pressure is set in advance, when the pressure at the water outlet end exceeds a set value within a certain range, the control system recognizes that the pressure is in an overpressure state at the moment, and immediately controls the motor water pump unit to stop running; when the pressure of the water inlet end is lower than a set value, the control system recognizes that the water is in a water shortage state at the moment, and immediately controls the motor water pump unit to stop running, so that equipment is prevented from being damaged by idling. When the water outlet pressure returns to normal, the control system identifies that the water outlet pressure is in a normal state at the moment and automatically starts the equipment; when the pressure of intaking resumes normally, control system discerns this moment for normal condition, and equipment is automatic to be opened equally.
The main functions of the components are:
① mechanical pressure gauge, which is a visual pressure detection device with upper and lower pressure limits;
② pressure sensor, invisible pressure detector, transmitting electronic signal to control system for identification;
③ control system consisting of PLC control module and electric shock equipment.
In the embodiment, when one of the sensor and the pressure gauge is damaged, the other one of the sensor and the pressure gauge also plays a role.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
