Description
Technical Field
The utility model relates to the technical field of motor cooling, in particular to an intelligent motor cooling monitoring system.
Background
The cooling method of the motor is mainly divided into direct cooling (internal cooling) and indirect cooling (external cooling), and common cooling modes thereof include:
air cooling: including natural cooling and forced cooling. In natural cooling, the motor cools the motor by natural wind generated by rotation of the rotor itself. In forced cooling, fans or special devices are installed inside and outside the motor to enhance the cooling effect. The cooling mode is suitable for clean, non-corrosive and non-explosive open type and drip-proof motors, and has high requirements on the use environment and occasions of the motors.
And (3) cooling hydrogen: in a high-speed motor, hydrogen is used for cooling, and in a closed system, hydrogen with a pressure which is higher than the atmospheric pressure by a few percent circulates through the inside of the motor by means of an internal fan, and then flows through a heating part of the motor and a tubular cooler. Although the cooling structure can effectively cool the motor, the cooler has larger volume and occupies a large amount of space.
And (3) oil cooling: some electric machines employ oil cooling, including oil cooling of stationary and rotating parts, which circulates through coolers inside the machine and outside the machine. In order to carry the oil out of the interior of the motor, a cooling system consisting of oil pipes, oil pumps, radiators and other accessories is required. This increases the cost and maintenance difficulty of the motor.
Under the condition that the motor power is continuously increased, the motor size is required to be kept small and the space of the installation position is limited, the traditional cooling mode is often difficult to meet the requirement. In order to effectively remove more heat, a cooling medium having a higher heat transfer capacity needs to be used, and the structure of the cooling system needs to be more compact. Therefore, the use of water cooling is certainly the best option. The water cooling adopts water as a primary cooling medium and is directly led into the stator or rotor hollow conductor of the motor, so that the cooling effect of the motor can be remarkably improved.
In order to reduce the cost, the water quality used for water cooling is generally more common, and certain impurities are contained in the water quality. Meanwhile, the water cooling pipe is heated for a long time, so that scale is very easy to form to cause pipeline blockage, and the cooling effect is affected. In addition, the water-cooled furnace cover is generally of an integral welding structure, and the whole water-cooled pipeline is relatively long. Therefore, when the water pipe is clogged, it is difficult to quickly determine the failure point. In addition, even if a fault point is found, the maintenance work is complicated and difficult to complete in a short time.
Disclosure of Invention

In order to achieve the above purpose, the present utility model provides a basic scheme: an intelligent motor cooling monitoring system is provided with a plurality of water-cooling pipe sections, wherein the water-cooling pipe sections are detachably connected and form a communicated water-cooling pipe in an end-to-end mode; the system also comprises a controller, a flow sensor and a temperature sensor, wherein the controller is electrically connected with the flow sensor and the temperature sensor; the flow sensors are arranged at the water inlet and the water outlet of the water cooling pipe, and at least one temperature sensor is arranged on each water cooling pipe section.
The basic scheme has the beneficial effects that: the current water inlet flow rate and the current water outlet flow rate of the water cooling pipe can be acquired through the flow sensor, the corresponding relation between the current water inlet flow rate and the water outlet flow rate of the water cooling pipe under normal conditions is stored in the controller, the current water inlet flow rate acquired through the flow sensor by the controller is matched with the normal water outlet flow rate, the current water outlet flow rate and the normal water outlet flow rate are compared through the comparator, and the water cooling pipe is possibly blocked when the deviation of the current water inlet flow rate and the normal water outlet flow rate is overlarge.
Due to the blockage of the water-cooled pipe section, the cooling water cannot smoothly pass through the water-cooled pipe section, so that the temperature of the water-cooled pipe gradually rises. Therefore, when the controller judges that the water cooling pipe is likely to be blocked, the temperature sensor is called to collect the temperature data of each water cooling pipe section, the specific water cooling pipe with problems is rapidly determined through the temperature sensor, namely, the fault point is rapidly determined, so that maintenance personnel can take measures in time, and due to the fact that the water cooling pipe adopts a modularized design, the water cooling pipe can be replaced or maintained in a targeted mode, maintenance efficiency is improved, and maintenance time is shortened.

The water inlet flow and the water outlet flow of the water cooling pipe are collected through the flow sensor, the controller compares the water inlet flow with the water outlet flow through the comparator, and when the deviation of the water inlet flow and the water outlet flow is overlarge, the water cooling pipe is indicated to be possibly leaked, so that maintenance personnel can be reminded to take measures in time.
According to the technical scheme, whether the blockage occurs is primarily judged through the flow sensor, more temperature sensors are called for fine judgment, energy can be saved, and meanwhile, the flow sensor can also detect the problem of cooling water leakage, so that the reliability of the technical scheme is improved.
As a preferable scheme, the temperature sensor adopts PT100 thermal resistor, and the PT100 thermal resistor is electrically connected with the controller through a temperature acquisition card.
The PT thermal resistor can normally work in various complex environments, has good high-temperature resistance and pressure resistance, can bear various severe working environments, and is suitable for the environment where the temperature sensor is located in the technical scheme.
As a preferable scheme, the display module is further arranged, and the input end of the display module is electrically connected with the display data output end of the controller.
The display module can display information such as the running state of the cooling system, so that the running condition of the cooling system can be more intuitively and carefully known.
Preferably, the display module adopts a liquid crystal display with a touch screen or operation keys.
The user can conveniently perform corresponding operation according to the displayed content.
As a preferable scheme, the intelligent alarm system is further provided with an alarm module, wherein the alarm module is electrically connected with the controller and comprises an audible and visual alarm.
The cooling system of the motor can be remarkably reminded of faults so as to remind maintenance personnel in time.
Preferably, the alarm module is further electrically connected with the display module and is used for transmitting alarm data.
The display module displays alarm data, so that on one hand, alarm reminding can be performed remarkably on a display interface, and on the other hand, various detailed data such as fault types and the like can be displayed, so that maintenance personnel can conveniently and rapidly know fault conditions.
As a preferable scheme, the remote terminal is further provided with a communication module, the communication module is in bidirectional communication connection with the controller, and the communication module is used for realizing communication between the controller and the remote terminal through a wired network or a wireless network.
