Detailed Description
As shown in fig. 1-3, a deep-well pump control system comprises a deep-well pump and a controller connected with a controlled end of the deep-well pump, wherein a main water pipe subsection 5 of the deep-well pump is tightly attached to a part to be cooled of the controller. In this embodiment, the portion to be cooled is a circuit board 3 inside the controller.
The shell 1 of the controller is of a fully-closed structure. Because the controller cools down for circuit board 3 in the controller through the deep-well water of main water pipe subsection 5 the inside, just can cool down for the controller through heat conduction promptly, avoided using among the prior art group to cool down through trompil installation fan on the controller to this kind of mode has improved the waterproof grade of whole controller. In this embodiment, the waterproof rating of the controller may be made IP55, thereby providing an environment for extending the useful life of the controller.
The groove structure 11 is a square groove, and the outer contour of the corresponding position of the main water pipe subsection 5 is also square. This prevents the controller from rotating relative to the main water pipe section. Optimally, supporting legs 2 are arranged below two sides of the shell, and a set distance is reserved between a main water pipe subsection (5) clamped in the clamping groove and the ground through the supporting legs 2.
Preferably, a second silicone layer 62 is arranged between the housing 1 and the main water pipe section 5, wherein the silicone layer not only serves for heat conduction, but also plays a role in lubrication, so that the main water pipe section 5 is smoothly inserted into the groove structure 11.
The controller also comprises a pressure sensor 4, and the detection end of the pressure sensor 4 extends into a detection hole on the pipe wall of the main water pipe subsection 5. And a sealing ring is arranged on the outer side wall of the detection part of the pressure sensor 4. In this way, the pressure sensor 4 is also effective in preventing water from escaping from the main water line section 5 when it detects the water pressure in the main water line section 5. The controller determines the real-time power of the deep-well pump by obtaining the value of the pressure sensor 4 and comparing the value with a threshold value, thereby ensuring that the water pressure in the main water pipe subsection 5 is in a stable state. The water inlet end of the main water pipe subsection 5 is provided with a water inlet joint 51, the water outlet end is provided with a water outlet joint 52, and optimally, the water inlet joint 51 is internally provided with a check valve to ensure that water in the main water pipe subsection 5 cannot flow back.
And the controller is externally connected with a liquid level sensor through a waterproof interface. Therefore, by detecting the liquid level of the area where the deep-well pump is located, when the controller reaches the preset value of the controller, the controller controls whether the deep-well pump works or not.
The main water pipe subsection 5 is connected with adjacent main water pipes on two sides through connecting pieces. This facilitates the nesting of the controller onto the main water pipe section 5.
The external power supply line and the control box of the controller are connected with an internal circuit board through a sealing mechanism on the shell 1, the sealing mechanism comprises a wire harness sleeve 61, a rubber sleeve 62 and a pressing cap 63, one end of the wire harness sleeve 61 is fixed in a mounting hole of the shell 1, the rubber sleeve 62 is arranged inside the other end of the wire harness sleeve, and the wire harness sleeve is pressed through the pressing cap 63. This ensures that the external wiring harness 6 of the controller is in a sealed state, such as the wiring harness 6 connected with a liquid level sensor and a power supply.
The invention can realize the automatic start and stop of the water pump based on some existing control circuits and control software, wherein the principle is as follows: when the deep-well pump is started up and normally runs, and when a user pressure tank is full or a valve is closed, the water pressure in the main water pipe section can gradually rise and exceed a preset stop value, the deep-well pump is stopped, and due to the existence of the check valve 7, the pressure of the main water pipe section can be kept for a long time; 3. when a user opens the valve, the pressure of the pipeline can be gradually reduced, and when the pressure is smaller than a preset starting value, the water pump can be started.
The invention can realize constant-pressure water supply based on some existing control circuits and control software, wherein the principle is as follows: the circuit board controls the power supply frequency of the motor in the deep-well pump, when the pressure value fed back by the pressure sensor 4 is greater than a set value, the circuit board reduces the output frequency and reduces the rotating speed of the motor, and when the pressure fed back by the pressure sensor 4 is less than the set value, the circuit board increases the output frequency and increases the rotating speed of the motor until the feedback pressure of the sensor is the same as the set pressure value.
It should be noted that what this scheme was mainly protected is control system's structure, rather than circuit structure, and circuit structure all belongs to prior art about measuring whether liquid level control deep-well pump worked among the circuit board 3, the real-time power that uses pressure sensor 4 to control the deep-well pump, this application improves control system's mechanical structure on the basis of prior art, in addition, the circuit can also realize functions such as anhydrous protection, undervoltage protection, lightning protection, open-phase protection, prevent surge current in this system, these functions are prior art, no longer describe in this concrete scheme again.
