Abstract
An on-line monitoring system for pump valve faults. The method comprises the steps that pressure values before and after opening and closing opening control of an electric regulating valve of a pipe network are carried out, the electric regulating valve is fed back in an online stable working mode, an electric control valve is needed to control a detection instrument pipeline, a first electric control valve is opened, a second electric control valve is closed, the instrument monitors the pressure of a water inlet pipe network of the electric regulating valve, the second electric control valve is opened, the first electric control valve is closed, the instrument monitors the pressure of a water outlet pipe of the electric regulating valve, a control signal is transmitted to a control unit, the working state of the electric regulating valve is analyzed, whether the electric regulating valve has a fault or not is judged, and the purpose of online monitoring is achieved. The utility model is used for a pump valve trouble on-line monitoring system.
Description
Technical Field
The utility model relates to a pump valve trouble on-line monitoring system.
Background
The existing pump valve fault on-line monitoring system realizes the judgment basis of the abnormal working of the pump valve by checking a mechanical instrument on site, the instruments are connected to the front end and the rear end of an electric regulating valve, the pressure difference value is observed on site, the monitoring of the working state of the pump valve on site cannot be realized by remotely detecting a pressure gauge in real time after the equipment is unattended, and the stable operation and the overhaul of the equipment are very inconvenient.
Disclosure of Invention
The utility model aims at providing a pump valve trouble on-line monitoring system.
The above purpose is realized by the following technical scheme:
the pump valve fault on-line monitoring system comprises a first electric control valve, a second electric control valve, an electric control valve, a detection instrument and a filter, wherein the detection instrument comprises an analog pressure gauge and a digital pressure gauge, the electric control valve is connected between the water inlet side or the water outlet side of the electric control valve and the detection instrument, and the electric control valve are connected with a control terminal.
The pump valve fault on-line monitoring system is characterized in that the electric regulating valve is connected with a filter and a pipe network.
The electric control valve control detection instrument displays the pressure difference between the front end and the rear end of the electric control valve, and the pressure difference judges whether the electric control valve has a fault.
Has the advantages that:
1. the utility model discloses a control electric control valve can guarantee not need to look over to the scene when maintaining, can remote operation, judges whether there is a fault in the electrical control valve according to operating condition.
2. The utility model discloses when carrying out fault determination, can remote drive electrical control valve opening, electrical control valve opens, through instrumentation feedback pressure value, judges whether electrical control valve and filter damage.
Description of the drawings:
FIG. 1 is a schematic diagram of the structure of the present invention;
in the figure: 1. an electric control valve 1; 2. a filter; 3. an electric control valve; 4. the electric control valve 2; 5. simulating a pressure gauge; 6. a digital pressure gauge.
The specific implementation mode is as follows:
example 1:
the pump valve fault on-line monitoring system comprises a first electric control valve and a second electric control valve, wherein the first electric control valve is connected with a detection instrument, a filter and an electric control valve, signals of the electric control valve come from a control terminal to control the pressure and flow of water in a pipe network, the first electric control valve is connected with a water inlet side and the detection instrument, the detection instrument displays the pressure of the water supply side, the second electric control valve is connected with the detection instrument, and the detection instrument displays the pressure of the water outlet side.
Example 2:
according to the pump valve fault on-line monitoring system in the embodiment 1, the electric control valve, the first electric control valve, the second electric control valve and the detecting instrument are connected.
The control terminal controls and detects the position opening of the electric regulating valve, the detection instrument is respectively connected with the water inlet side pipeline and the water outlet side pipeline by controlling the first electric control valve and the second electric control valve, and the detection instrument displays the pressure difference value of the water inlet side and the water outlet side.
Example 3:
according to the pump valve fault on-line monitoring system in embodiment 2, the detection instrument uploads the pressure value to the control terminal, and whether the pump valve has a fault is judged according to the pressure value.
Claims (3)
