Fluid pressurization controller

A fluid pressurization controller, particularly a pressurization controller for controlling a pressurizing device, maintaining a certain pressure of the pressurizing device, and preventing the pressurizing device from being activated for a long time, resulting in a reduced service life.

Press, the fluid pressurizing device is used in areas where water pressure is insufficient, or equipment that needs to be switched by water pressure (such as water heater). At present, most of the pressurizing devices use a pump to connect the pressure tank to allow connection. The liquid in the line of the pressure device can maintain a certain pressure, and the current pressurizing device has the following defects:

1. If the equipment at the end of use is not used for a long time, the pressurizing device will not operate, resulting in the lubricating fluid of the inner shaft seal of the pump, which cannot infiltrate the entire shaft seal. When the pump is started again, the shaft seal will generate a large amount of moments. Wear, the service life of the pump is reduced, and the shaft seal is sticky, the water blade is stuck, etc., and the pump cannot be used.

Second, in order to prevent the continuous operation of the pump in the waterless state, most of them will be installed on the inlet pipe by the float switch or the reed switch to control the pump to stop when it is not water, but if the float switch or the reed switch is damaged, the pump The pump will operate for a long time in the absence of water, causing damage to the pump.

Therefore, how to solve the above-mentioned problems and shortcomings is the subject of research and development that the relevant industry is eager to develop.

The main purpose of the present invention is to use the control device to start the operation at a fixed interval in a state in which the pressurizing device is not in operation to maintain the pumping of the pressurizing device. The shaft seal is lubricated to prevent the pump from being worn out for a long time, resulting in a large amount of wear on the shaft seal, which reduces the pump life and prevents the shaft seal from sticking and the water leaf jamming. In other cases, the pump cannot be used.

The secondary purpose of the present invention is that the control device activates the pump at a fixed interval when the pressure of the pressurizing device is insufficient to prevent the pressurizing device from operating for a long time in the absence of water, resulting in damage to the pressurizing device.

In order to achieve the above object, the pressure controller of the present invention is provided with a pressurizing device and a control device, the pressurizing device has a pump, and a pressure tank connected to the pump, the control device has a microprocessor, and is connected to the micro The processor controller and the detector are connected to the pump, the detector is connected to the pressure tank, the microprocessor is set with the pressure setting value and the protection starting time setting value, and the detector continuously detects Measuring the pressure value of the pressure barrel and transmitting it to the microprocessor, the microprocessor compares the pressure value of the pressure barrel with the pressure setting value, and when the pressure value of the pressure barrel is lower than the pressure setting value, the microprocessor controls the controller to make The pump operates for a certain period of time. When the pressure value of the pressure tank is higher than the pressure set value, the microprocessor starts to accumulate the time when the pump is not operated, and when the unoperated time reaches the set value of the protection start time, the microprocessor controls the control. The pump is operated for a certain period of time.

In the above pressure controller, the microprocessor is further configured with a first self-starting time setting value and a second self-starting time setting value, wherein the second self-starting time setting value is greater than the first self-starting time setting value, when The pressure barrel pressure value transmitted by the detector is lower than the pressure setting value, and the pressure control barrel pressure value transmitted by the detector is lower than the pressure setting value after the microprocessor controls the controller to operate for a certain period of time. The processor accumulates the pressure barrel pressure insufficient time according to the first self-starting time setting value. When the pressure barrel pressure is insufficient to reach the first self-starting time setting value, the microprocessor controls the controller to make the pump operate for a certain time and detects again. Measuring the pressure value of the pressure tank, and when the pressure value of the pressure drum of the microprocessor is lower than the pressure setting value, The microprocessor accumulates the pressure barrel pressure insufficient time according to the second self-starting time setting value. When the pressure barrel pressure is insufficient to reach the second self-starting time setting value, the microprocessor controls the controller to make the pump operate for a certain time.

The first picture is a block diagram of the creation.

Referring to the first figure, it can be clearly seen from the figure that the creation system is provided with a pressurizing device 1 and a control device 2, wherein the pressurizing device 1 has a pump 11 and a pressure connected to the pump 11. Bucket 12.

The control device 2 has a microprocessor 21, and a controller 22 and a detector 23 connected to the microprocessor 21. The controller 22 is connected to the pump 11, and the detector 23 is connected to the pressure tank 12, and The processor 21 is configured with a pressure set value 211, a protection start time set value 212, a first self-start time set value 213 and a second self-start time set value 214, and the second self-start time set value 214 is greater than the first self-start time. Set value 213.

By the way, the detector 23 continuously detects the pressure value of the pressure tank 12 and transmits the pressure value of the pressure tank 12 to the microprocessor 21. After receiving the pressure value of the pressure tank 12, the microprocessor 21 will The pressure value is compared with the pressure set value 211. When the pressure value of the pressure tank 12 is lower than the pressure set value 211, the microprocessor 21 controls the controller 22 to cause the controller 22 to operate the pump 11 for a certain period of time. After the pump 11 stops operating, the microprocessor 21 receives the pressure value of the pressure tank 12 again by the detector 23 and compares the pressure set value 211. If the pressure value of the pressure tank 12 is higher than the pressure set value 211 The microprocessor 21 starts accumulating the time when the pump 11 is not operating, and when the non-operating time reaches the protection start time set value 212, the microprocessor 21 controls the controller 22 to operate the pump 11 for a certain period of time.

Moreover, if the pump 11 stops operating, the microprocessor 21 receives the pressure value of the pressure tank 12 again by the detector 23, and compares the pressure set value 211, and the pressure value of the pressure tank 12 is lower than the pressure setting. When the value is 211, it means that the pressing device 1 is in a waterless state. At this time, the microprocessor 21 accumulates the pressure barrel 12 under pressure according to the first self-starting time setting value 213, and when the pressure barrel 12 is under pressure, the first self is reached. When the time set value 213 is activated, the microprocessor 21 controls the controller 22 to operate the pump 11 for a certain period of time, and again receives the pressure value of the pressure tank 12 from the detector 23, and compares the pressure set value 211. If the pressure value of the pressure tank 12 is still lower than the pressure set value 211, the microprocessor 21 accumulates the pressure barrel 12 under pressure time according to the second self-start time set value 214, and reaches the second self-start time setting when the pressure tank 12 is under pressure. At a value of 214, the microprocessor 21 controls the controller 22 to operate the pump 11 for a certain period of time, and again receives the pressure value of the pressure tank 12 from the detector 23, and compares the pressure set value 211 until the pressure tank 1 If the pressure value of 2 is greater than the pressure set value 211, it means that the pressurizing device 1 has restored the water supply, and then returns to the previous action, so that the microprocessor 21 accumulates the time when the pump 11 is not operated according to the protection start time set value 212.

Therefore, this creation is to solve the shortcomings and defects of the prior art, and can improve the efficiency. The key technologies are:

(1) The creation uses the protection start time setting value 212 set by the microprocessor 21 to protect the pump 11 from the normal water supply state, and the pump 11 is not operated for an excessive period of time, resulting in re-operation. Since the pump 11 shaft seal is not completely lubricated by the lubricating fluid, a large amount of wear is caused, and the problem that the shaft seal is stuck, the water blade is stuck, and the like, and the pump cannot be used may occur.

(2) The present invention uses the microprocessor 21 to control the pressure value of the pressure tank 12 after the operation of the pump 11 by the controller 22 to determine whether the pressurizing device 1 is in a waterless state or a water supply state, and if it is in a water supply state, the protection start time is protected. Set value 212 to prevent pumping 11 The shaft seal generates a large amount of wear. If it is in a waterless state, the microprocessor 21 uses the first self-starting time set value 213 or the second self-starting time set value 214, and the interval control controller 22 operates the pump 11 to determine the pressurization. The water supply condition of the device 1 can prevent the pump 11 from continuing to operate and cause damage.
