Abstract
The utility model relates to an alarm device of valve blocking failure of a membrane pump check valve suitable for automatic alarming of the valve blocking failure of the membrane pump check valve for slurry pipeline conveying. A first pressure sensor is installed on a discharge outlet of a hydraulic end of a membrane pump, a second pressure sensor is installed on a feed inlet, and a third pressure sensor is installed in the inner side of the membrane pump. The first pressure sensor, the second pressure sensor and the third pressure sensor are connected with a controller through corresponding data lines. The first pressure sensor and the second pressure sensor are installed on the outer side of the check valve. When failure occurs on the check valve, the first pressure sensor, the second pressure sensor and the third pressure sensor can detect fluctuating change of pressure, a processor analyzes out failure position according to fluctuating condition of the pressure, and then feeds back the failure position to an alarm, and the target of failure automatic alarm is achieved.
Description
Affiliated technical field
The utility model relates to a kind of diaphragm pump one-way valve card valve accident warning device, can be widely used in the diaphragm pump of Slurry Pipeline Transportation and other pipework projects, use as diaphragm pump one-way valve card valve fault measuring warning facility, belong to diaphragm pump faut detection warning facility technical field.
Background technique
Before the utility model is made, the one-way valve card valve fault that diaphragm pump rate of fault in service is the highest judges that main experience by operation, maintenance man checks judgement, this detecting method was both lost time, simultaneously again because artificial subjective factor is many, make the diaphragm pump device fault information that obtains inaccurate, influenced the normal safe operation of diaphragm pump and even pipeline.
Summary of the invention
In order to solve the accurate judgement warning problem of diaphragm pump one-way valve card valve fault, improve existing diaphragm pump one-way valve card valve faut detection alarm method, improve and detect science, guarantee the normal safe operation of pipe-line system, the utility model provides a kind of diaphragm pump one-way valve card valve accident warning device, this diaphragm pump one-way valve card valve accident warning device is simple in structure, easy for installation, and warning message accurately and reliably.
The technological scheme that its technical problem that solves the utility model adopts is: it is at the discharge port place of membrane pump fluid end the I pressure transducer to be installed, the II pressure transducer is installed at the material feeding mouth place, at barrier film installed inside III pressure transducer, they are connected with controller by corresponding datawire, wherein, alarm is connected with processor by corresponding datawire, I pressure transducer and II pressure transducer are installed in the one-way valve outside, when one-way valve breaks down, the I pressure transducer, the fluctuation that II pressure transducer and III pressure transducer will detect pressure changes, processor obtains abort situation according to the pressure surge situation analysis, feed back to alarm then, reach the automatic failure alarm purpose.
The beneficial effects of the utility model are to use as diaphragm pump one-way valve card valve malfunction alarm equipment for the diaphragm pump of any Slurry Pipeline Transportation construction project, warning message accurately and reliably, simple in structure, easy for installation, guaranteed the normal safe operation of slurry pipeline.
