Description
A method for controlling a vacuum pump with motion retention Technical Field
[0001] The present invention relates to the technical field of vacuum pumps, and in particular to a method for controlling a vacuum pump with action retention. Background Art
[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container to create a vacuum. Generally speaking, a vacuum pump uses various methods to improve, create, and maintain a vacuum in a closed space. Dry screw vacuum pumps, in particular, operate in complex manufacturing processes and power supply environments. In remote cities, power supply fluctuations can occur to varying degrees, especially in the event of a power outage. Automatic reset of the pump within a specified timeframe is crucial. Some equipment uses high-frequency power supplies, which can have varying impacts on the power supply. Power surges can damage transformers and fuses.
[0003] For example, patent number CN201720772019.7 discloses: "A dry screw vacuum pump automatic operation device mainly includes a vacuum pump, an air intake assembly, a cooling water return assembly, an exhaust assembly, a cooling water supply assembly, and a purge gas supply assembly, characterized in that: a first temperature monitoring transmitter, a first pressure monitoring transmitter, a first electric signal-controlled pneumatic butterfly valve, and the air intake of the vacuum pump are connected in series. A third pressure monitoring transmitter, a second electric signal-controlled pneumatic ball valve, and the cooling water return port of the vacuum pump are connected in series. A second pressure monitoring transmitter, a second electric signal-controlled pneumatic butterfly valve, and the exhaust port of the vacuum pump are connected in series. A second temperature monitoring transmitter, a pressure transmitter, a flow transmitter, a first electric signal-controlled pneumatic ball valve, and the cooling water supply port of the vacuum pump are connected in series. A third temperature monitoring transmitter, a fourth pressure monitoring transmitter, a flow monitoring transmitter, a third electric signal-controlled pneumatic ball valve, and the purge gas supply port of the vacuum pump are connected in series. The vacuum pump can be remotely controlled, started, operated, and shut down."
[0004] The above-mentioned technology and the existing technology have the following defects: when the vacuum pump loses power, the operating command output cannot be maintained instantaneously, and there is a lack of stable connection of electrical components, resulting in power outages similar to lightning weather. The vacuum pump control system faces a complex power supply environment and has no ability to cope with surges and power outages. When the power supply is abnormal, the unit will lose power and shut down, and cannot provide a stable vacuum source. Therefore, the present application provides a vacuum pump control method with action maintenance to meet the needs.
[0005] Summary of the Invention
[0006] The technical problem to be solved by the present invention is to provide a vacuum pump control method with action retention to solve the problem that the existing vacuum pump control system faces complex power supply environments, has no ability to cope with surges and power outages, and when the power supply is abnormal, the unit will lose power, the unit will shut down, and cannot provide a stable vacuum source.

[0009] The three-phase filter is used to remove ineffective high-frequency filtering, AC noise, and power supply fluctuations on the power supply board. The three-phase filter is connected to a transformer, which is used to convert current and control current output stability. The transformer is unidirectionally electrically connected to a unidirectional filter, which is used to improve load stability and increase system efficiency.

[0013] Preferably, the electronic control panel identifies the power outage result and is used to maintain the operation command output so that it can successfully resume operation within 1 minute, reducing the hardware damage rate and pump mechanical loss. The electronic control panel is connected to a start-up delay module. After the power is cut off, the start-up delay time can be set to ensure that the power supply is stable before starting the vacuum pump through the electronic control panel to avoid problems that may be caused by starting during power fluctuations.
[0014] Preferably, when the power board is powered off, the electric control board recognizes the power off and shields the alarm signal output by the inverter, and resumes monitoring of the alarm signal 10 seconds after power is restored.
[0015] Preferably, the power failure problem is sent to the alarm module through the electronic control panel, and the alarm is recorded as "power failure".
[0016] Preferably, the system connection process includes a vacuum pump, a three-phase filter, a transformer, a single-phase filter, a surge absorber, and an electronic control board, wherein the vacuum pump is connected to the electronic control board, and a stable power supply is provided to the electronic control board through the three-phase filter, the single-phase filter, the surge absorber, and the transformer to absorb the conversion current and interference in the circuit.
[0017] Preferably, the power supply maintaining element of the electronic control board realizes the power supply maintenance of the control board, keeps the vacuum pump in action, and the electronic control board adds the judgment condition of power off of the switch power supply to ensure the output of the operation command.
[0018] Preferably, the alarm signal monitoring is restored 10 seconds after power is restored, the electric control panel sends a power failure message to the alarm module, and the alarm is recorded as "power failure".
[0019] Compared with the prior art, the present invention has at least the following beneficial effects:
[0020] 1. In the above scheme, by setting up an electronic control board, the operation command output can be maintained when the power board is powered off. The circuit is connected through the power board capacitor board, and the stored electrical energy is used to keep the electronic control board powered and the operation command output state. By setting up a start delay module, the automatic start is delayed after the power is cut off. After ensuring that the power supply is stable, the vacuum pump is started through the electronic control board to avoid problems that may be caused by starting during power fluctuations.
[0021] 2. By setting up the alarm module, the alarm processing when the power board is powered off, when the power board is powered off, the electronic control board can shield the alarm signal output by electrical components such as the inverter, and start power restoration through the electronic control board. After the power board is restored to power, the alarm signal monitoring will be responded to 10 seconds to ensure the normal operation of the system.
[0022] 3. By setting the alarm module to record the power failure alarm, when the power fails, the control panel will record the alarm as "power failure" so that maintenance personnel can quickly check and repair.
[0023] 4. By setting the power supply to connect a three-phase filter and a transformer, the ineffective high-frequency filtering, AC noise, and power fluctuation interference on the power supply board are removed, and the load stability is improved, thereby improving system efficiency.
