Abstract
The utility model relates to a structure for the rotating speed measurement and the counter-rotating protection of a boiler feed pump, which comprises a feed pump and a pump coupling. The structure is characterized in that the outer circle of the coupling is opened with grooves and the number of the grooves is a multiple of three. The grooves are uniformly distributed. The bearing cap of the feed pump is equipped with a fixed rotating speed sensor and the fixed rotating speed sensor is connected with a display. The probe of the fixed rotating speed sensor faces the gaps between the grooves. By adopting the above structure, an alarm is given for the counter-rotating of a boiler feed pump, so that the shutdown processing can be performed timely by operators on site. Meanwhile, the operation status of the boiler feed pump is monitored by the operators on site and the output power of the boiler feed pump can be adjusted timely. Therefore, the safety and the economical operation of a set can be guaranteed.
Description
Technical field
The utility model relates to a kind of structure that can carry out tachometric survey and reversal protection to boiler feed pump.
Background technique
Existing boiler feed pump can not directly be measured revolution speed and to the reversal protection of pump; this makes the staff can not accurately and timely monitor the operation conditions of boiler feed pump; so that not enough or cross situation such as exert oneself and can not make effectively and judging exactly to pump counter-rotating and boiler output, cause the unit can not be safely and operation economically.
Summary of the invention
The purpose of this utility model is that boiler feed pump can not directly be measured revolution speed and to the existing problem of the reversal protection of pump, provide a kind of structure that can carry out tachometric survey and reversal protection to boiler feed pump in the solution prior art.A kind of structure that can carry out tachometric survey and reversal protection to boiler feed pump of the utility model design; comprise feed water pump, pump end coupling; it is characterized in that: on the little cylindrical of coupling, offer groove; the groove number is 3 multiple; groove evenly distributes; install and fix speed probe on the bearing cap of feed water pump, the probe of fixed rotating speed sensor is relative with the groove gap, and the fixed rotating speed sensor is connected to display device.The utility model has the advantages that and to make warning to the counter-rotating of pump, make the field personnel can shut down processing timely; The field personnel can monitor the operation conditions of boiler feed pump, can regulate timely exerting oneself of boiler feed pump, and the safety of unit and economical operation are guaranteed.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.Accompanying drawing 2 is that the k of Fig. 1 is to schematic representation.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment
Comprise feed water pump 1, pump end coupling 2 among the figure, it is characterized in that: on the little cylindrical of pump end coupling, offer groove 3, the groove number is 3 multiple, groove evenly distributes, on the bearing cap 4 of feed water pump, install and fix speed probe 5, the probe of fixed rotating speed sensor is relative with the groove gap, and the fixed rotating speed sensor is connected to display device 6.
When running; the fixed rotating speed sensor rotates the groove on the pump end coupling and detects; data send display device to show; whether the staff can rotate normal to feed water pump by display monitoring; the field personnel can in time monitor the operation conditions of boiler feed pump, in case generation speed is lower than the value of setting or reverses, the field personnel can handle and shut down; exerting oneself of boiler feed pump regulated, the safety of unit and economical operation are guaranteed.
