[0009] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is combined with the embodiment, and the utility model is further detailed.The specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0010] The specific implementation of this utility model will be described in detail below with reference to specific embodiments:

[0011] like Figure 1 As shown, a water pump and fan pressure and current monitoring device includes: an MDO longitudinal tensioning unit and a TDO transverse tensioning unit. The MDO longitudinal tensioning unit is connected to an MDO water pump via a pipeline, and a pressure sensor is installed on the pipeline. The MDO water pump is electrically connected to a water pump current transmitter. The TDO transverse tensioning unit is connected to a TDO fan, and the TDO fan is electrically connected to a fan current transmitter. The pressure sensor, water pump current transmitter, and fan current transmitter are all electrically connected to an alarm.

[0012] The alarm is an audible and visual alarm.

[0013] A pressure sensor is installed on the outlet pipeline of the MDO water pump to collect the pump pressure. A current transmitter is installed on the current lines of the MDO water pump and the TDO fan to collect the fan current. Upper and lower alarm limits can be set. When the collected data reaches the upper or lower alarm limits, an audible and visual alarm will be triggered, allowing operators to analyze and handle the anomaly. Pressure detection and current acquisition are existing technologies, and will not be described in detail here.

[0014] In this embodiment of the invention, to address the frequent issues of water shortage causing heater burnout in the heat exchange platform, or high pressure without timely venting leading to water replenishment failure, the pump pressure and current of the heat exchange platform are collected in real time. Upper and lower limit alarms are set for pressure and current based on their respective operating conditions. Alarms are triggered when the pressure and current reach the upper or lower limits. The TDO fan current is also collected simultaneously. By monitoring the fan operating current, abnormal current can be detected by checking the damper opening, or by adding or replacing the motor bearings if they are low on lubrication. This improvement aims to reduce heater wear and indirectly improve the quality of the sheet material.

[0015] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
