Problems solved by technology

Since the rotor is inside the pump casing, it cannot dissipate heat. When the vacuum pump is overheated, the energy consumption of the vacuum pump will increase a lot, increasing energy consumption.
At the same time, the existing Roots vacuum pump control system cannot monitor the operating data of the vacuum pump in real time and perform early warning analysis, resulting in a decrease in the working efficiency of the Roots vacuum pump

Embodiment 1

[0053] Such as figure 2 As shown, the pressure sensor: installed at the exhaust port of the vacuum pump, used to collect the pressure at the exhaust port of the vacuum pump in real time and send it to the data analysis module;

[0054] Data analysis module: used to obtain the pressure at the exhaust port of the vacuum pump and compare the pressure with the set value. If the pressure at the exhaust port of the vacuum pump is greater than the set value, a pressure adjustment signal is generated;

[0055] The data analysis module is used to transmit the pressure adjustment signal to the controller, and the controller drives and controls the pressure adjustment module to adjust the pressure after receiving the pressure adjustment signal;

[0056] The pressure adjustment module is used to control the opening of the corresponding overflow solenoid valve according to the pressure difference between the current pressure and the set value, and adjust the ratio of the power of the vacu...

[0060] The temperature adjustment module is a condenser, which is used to control the temperature of the cooling water flowing through the vacuum pump through the condenser according to the current temperature of the inner wall of the vacuum pump casing and the outer wall of the pump casing, so as to dissipate heat from the vacuum pump; the specific control method is as follows:

[0061] Step 1: Obtain the current temperature of the inner wall of the pump casing and the outer wall of the pump casin...

Embodiment 3

[0069] Such as Figure 4 As shown, the operation monitoring module is used to collect and analyze the operation data of the vacuum pump to judge whether the vacuum pump is running normally. The specific analysis and monitoring process is as follows:

[0070] S1: Collect the operation data of the vacuum pump, mark the noise decibel value of the vacuum pump during operation as Z1, mark the energy consumption per unit time of the vacuum pump as Z2, and mark the difference between the inner wall temperature of the vacuum pump casing and the ambient temperature as Z3;

[0071] S2: Use the formula GX=Z1×a1+Z2×a2+Z3×a3 to calculate the operation detection coefficient GX of the vacuum pump, where a1, a2 and a3 are coefficient factors;

[0072] S3: Comparing the running detection coefficient GX with the detection coefficient threshold;

[0073] If the operation detection coefficient GX≥the detection coefficient threshold, it means that the vacuum pump is in a suspected dangerous stat...

Abstract

The invention discloses an energy-saving control system based on a roots vacuum pump, and relates to the technical field of vacuum pumps. The energy-saving control system comprises a pressure sensor, a pressure adjusting module, a temperature sensor, a temperature adjusting module, an operation monitoring module and an alarm module; the pressure sensor is used for collecting the pressure of an exhaust port of the vacuum pump in real time, and the pressure adjusting module is used for controlling a corresponding overflow electromagnetic valve to be opened according to the pressure difference between the current pressure and a set value and adjusting the ratio of the power to the pressure difference of the vacuum pump to enable the power to be matched with the pressure difference to reach a balance point to ensure that the vacuum pump works under rated working current, so that overload phenomenon is avoided; and the temperature adjusting module is used for automatically controlling the temperature of cooling water flowing through the vacuum pump from a condenser, the mode that the temperatures are controlled to be different in the different internal and external temperature difference interval is adopted, the cooling heat dissipation speed of the vacuum pump in the high-load time period is increased, and energy consumption of the vacuum pump in the low-load time period is reduced, so that purposes of saving energy and improving the working efficiency of the vacuum pump are achieved.

Description

technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to an energy-saving control system based on Roots vacuum pumps. Background technique [0002] Roots vacuum pumps have the advantages of quick start, low power consumption, low operation and maintenance costs, and high efficiency, and are widely used in industrial and mining enterprises. Roots vacuum pumps are also widely used in the paper processing industry. The working process is that the rotor sucks air into the casing from the air inlet, then enters the exhaust pipe from the air outlet, and then is transported out by the exhaust pipe; [0003] However, the power required by the Roots vacuum pump to compress the gas is proportional to the pressure difference. Once the gas pressure difference is too high, the pump may be overloaded; and on the inside of the end cap. When the inner side of the end cover and the inner wall of the pump casing receive heat, they will heat up an...
