Description

Technical Field

[0001] The utility model relates to the technical field of air compression station cooling, in particular to a cooling water pressure display and control device for an air compression station. Background Art

[0002] An air compressor station is a compressed air station, which consists of an air compressor, an air storage tank, air treatment and purification equipment, and a cold dryer. An air compressor is a device that converts the mechanical energy of a prime mover (usually an electric motor) into gas pressure energy; since air generates high temperature after compression, air compressors are usually equipped with a water cooling system to reduce the temperature of the unit; other equipment in the air compressor station generates heat during operation, and a water cooling system is also required.

[0003] Usually, the water cooling system of the air compressor is coordinated with a cooling tower, a water tank and a water pump. The cooling water in the water tank flows to the water pump, and the water pump delivers the cooling water to the air compressor. The cooling water becomes hot water after heat exchange in the air compressor. The hot water then flows into the cooling tower, becomes cold water after being cooled by the cooling tower, and finally returns to the water tank. When the water pump fails, the cooling water stops circulating or the speed of the cooling water flowing into the air compressor slows down. The heat generated by the air compressor during operation cannot be dissipated in time, and the air compressor is in a high temperature state for a long time, which is easy to cause damage to the air compressor.

[0004] The traditional technical solution is to set up multiple parallel water pumps to drive cooling water, and the staff will go to the water pump room regularly to check whether the water pumps are operating normally; and when one of the water pumps or more than two water pumps fail, the water pressure in the cooling water delivery pipeline becomes low, and the speed of cooling water flowing into the air compressor becomes slower. When the staff finds that the heating temperature of the air compressor is too high, they infer that the water pump has failed, which has a delay and it is difficult for the staff to go to the water pump room in time to repair the water pump; in the water pump room, due to the interference of the vibration sound emitted by the water pump in normal working condition, it is difficult for the staff to quickly find the location of the faulty water pump by sound. The faulty water pump is divided into two situations: the water pump stops running and the water pump speed is too slow. The water pump with too slow speed will still produce vibration sound; the staff needs to spend more time to detect whether multiple related water pumps are operating normally.

[0005] Therefore, how to send out an alarm signal when a water pump in an air compressor station fails, and how to quickly locate the failed water pump, is a technical problem that urgently needs to be solved in the art. Utility Model Content

DETAILED DESCRIPTION

[0021] The embodiment of the utility model provides a cooling water pressure display and control device for an air compressor station, which overcomes the shortcomings in the background technology that when a water pump in the air compressor station fails, it is difficult for the staff to go to the water pump room in time to repair the water pump, and it is difficult for the staff to quickly find the location of the faulty water pump by sound; it realizes the technical effect that when a water pump in the air compressor station fails, the water pressure in the cooling water delivery pipeline becomes low, the water pressure of the cooling water delivery pipeline is detected in real time by a water pressure sensor, and an alarm sends an alarm signal to notify the staff. After the staff arrives at the water pump room, they can quickly find the location of the faulty water pump by observing the speed display located in the control cabinet and the water pump serial number label paper.

[0022] The overall idea of ​​the technical solution of the embodiment of the utility model is as follows:

[0023] Add water pressure sensors, water pressure displays, water pressure alarms, speed sensors and speed displays to the cooling water drive components, and add pump serial number labels to the control cabinet; the water pumps of multiple cooling water drive components are set in parallel. When one of the water pumps fails, the water pressure in the cooling water delivery pipeline becomes lower. As the number of failed water pumps increases, the water pressure in the cooling water delivery pipeline drops more. The water pressure sensor detects the water pressure in the cooling water delivery pipeline in real time. The staff can understand the current cooling water pressure by observing the water pressure display and preliminarily understand the number of failed water pumps; when the water pressure is lower than the normal level, the water pressure alarm will send an alarm signal to notify the staff to go to the water pump room in time.

[0024] The speed sensor detects the shaft speed of the water pump in real time and feeds back to the speed display; when the staff sees that the speed display is zero or the speed is lower than the normal value, they know clearly that the water pump has a fault. With the help of the water pump serial number label paper, they can confirm the location of the faulty water pump on site. The staff will go to repair the water pump, saving the staff's time in detecting the water pump and quickly finding the location of the faulty water pump.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See also Figure 1 and Figure 2 , a preferred embodiment of the utility model.

[0027] A cooling water pressure display and control device for an air compressor station, comprising:

[0028] Cooling water drive assembly 1, cooling water delivery pipeline 2, water pressure sensor 3, water pressure display 4, water pressure alarm 5 and control cabinet 6;

[0029] The cooling water drive assembly 1 includes a water pump 11, a one-way valve 12, a speed sensor 13, a speed display 14 and a water pump operation panel 15, the water outlet of the water pump 11 is connected to the water inlet of the one-way valve 12, the water outlet of the one-way valve 12 is connected to the cooling water delivery pipeline 2, the water pump operation panel 15 is electrically connected to the water pump 11, the speed sensor 13 is installed on the water pump 11, and is used to detect the rotation speed of the shaft of the water pump 11, and the speed sensor 13 is electrically connected to the speed display 14;

[0030] The water pressure sensor 3 is installed in the cooling water delivery pipeline 2, the water pressure sensor 3 is electrically connected to the water pressure display 4, and the water pressure display 4 is electrically connected to the water pressure alarm 5;

[0031] There are multiple cooling water drive components 1, and the control cabinet 6 is also affixed with water pump serial number labels 61. The number of water pump serial number labels 61 is consistent with the number of cooling water drive components 1. The speed display 14 and the water pump operation panel 15 are both fixedly arranged in the control cabinet 6.

[0032] The water pressure sensor 3 detects the water pressure of the cooling water delivery pipeline 2 in real time and feeds it back to the water pressure display 4. The staff can understand the current water pressure of the cooling water from the water pressure display 4; when the water pump 11 of the air compressor station fails, the water pressure of the cooling water delivery pipeline 2 becomes low, and the water pressure alarm 5 sends an alarm signal to notify the staff to go to the water pump room 8 to repair the water pump in time; the speed sensor 13 detects the shaft speed of the water pump 11 in real time and feeds it back to the speed display 14. After the staff arrives at the water pump room 8, they observe the speed display 14 located in the control cabinet 6 and the water pump serial number label paper 61, and they can clearly know which water pump is working normally and which water pump is faulty, and quickly find out the location of the faulty water pump. The staff cuts off the power supply of the water pump through the button switch of the water pump operation panel 15, and then quickly repairs the water pump.

[0033] For example, there are four cooling water drive components 1, that is, four water pumps are arranged in parallel. The water pump, the one-way valve 12, the speed sensor 13, the speed display 14, the water pump serial number label 61, and the water pump operation panel 15 are all one-to-one corresponding. The four water pump serial number labels 61 located in the control cabinet 6 are filled with the serial numbers "1#", "2#", "3#", and "4#", respectively, and the water pumps on site are also affixed with corresponding water pump serial number labels 61. Under normal circumstances, the four water pumps work at the same time, and the water pressure of the cooling water delivery pipeline 2 is at a normal level; when one of the water pumps fails, the water pressure of the cooling water delivery pipeline 2 becomes lower, and as the number of failed water pumps increases, the water pressure of the cooling water delivery pipeline 2 drops more. The water pressure display 4 is a digital tube; the water pressure alarm 5 is a buzzer. The staff can understand the current cooling water pressure by observing the water pressure display 4 and preliminarily judge the number of faulty water pumps; the water pressure display 4 sends the current water pressure signal to the water pressure alarm 5, the water pressure alarm 5 has an MCU, and the MCU stores a preset water pressure threshold. The MCU compares the received water pressure signal with the preset water pressure threshold. When the received water pressure signal is lower than the preset water pressure threshold, the water pressure alarm 5 sends an alarm signal; when the received water pressure signal is equal to or higher than the preset water pressure threshold, the water pressure alarm 5 stops sending the alarm signal.

[0034] The water pump 11, such as a vane pump, transfers energy by the interaction between rotating vanes and water. The vanes are fixedly mounted on a rotating shaft, which is connected to the output shaft of a motor through a coupling, and the motor drives the vanes to rotate. The speed sensor 13 is used to detect the speed of the rotating shaft.

[0035] It also includes a duty room 7 and a pump room 8;

[0036] The water pressure display 4 and the water pressure alarm 5 are both in the duty room 7, and the cooling water drive assembly 1, the cooling water delivery pipeline 2, the water pressure sensor 3, and the control cabinet 6 are all in the water pump room 8. The beneficial effect of this technical solution is that the staff can understand the current water pressure of the cooling water delivery pipeline 2 in the duty room 7, and move to the water pump room 8 after hearing the alarm signal from the water pressure alarm 5. Since the water pump 11 makes a vibration sound when working, the staff in the duty room 7 can effectively avoid being disturbed by the vibration sound; the staff will move to the water pump room 8 when needed.

[0037] The cooling water drive assembly 1 also includes a manual ball valve 16, which is installed at the water inlet of the water pump 11. The cooling water delivery pipeline 2 is also connected to the water inlet of the air compressor 10, the water outlet of the air compressor 10 is connected to the hot water delivery pipeline 101, the hot water delivery pipeline 101 is also connected to the water inlet of the cooling tower 102, the water outlet of the cooling tower 102 is connected to the water inlet of the water tank 103, and the water outlet of the water tank 103 is connected to the water inlet of the water pump 11. The beneficial effect of this technical solution is that before repairing the water pump 11, the staff closes the manual ball valve 16 to prevent the water in the water tank 103 from flowing to the water pump 11 to be repaired, which facilitates the disassembly of the water pump 11. When the water pump 11 is working normally, the manual ball valve 16 is in an open state.

[0038] The cooling water drive assembly 1 also includes a status indicator light 17, which is electrically connected to the speed display 14 and is fixedly arranged on the control cabinet 6. The beneficial effect of this technical solution is that it helps the staff to quickly troubleshoot the faulty water pump 11. The MCU of the speed display 14 stores a preset speed threshold, and compares the speed signal received from the speed sensor 13. When the speed is lower than the set speed threshold, the status indicator light 17 emits red light, and when the speed is equal to or higher than the set speed threshold, the status indicator light 17 emits green light.

[0039] The working mode of the utility model is as follows: after the staff in the duty room 7 hears the alarm signal of the water pressure alarm 5, they check the water pressure display 4 to preliminarily understand the number of water pumps that have failed; the staff promptly moves to the water pump room 8, checks the speed display 14 and the status indicator 17 in the control cabinet 6, and the speed corresponding to the water pump 11 that has failed is zero or the speed is lower than the normal value, and then the staff disconnects the power supply of the corresponding water pump 11 through the water pump operation panel 15, and then finds the location of the failed water pump 11 on site according to the water pump serial number label paper 61, and repairs the water pump 11. A parallel standby water pump is also set in the water pump room 8. In the process of repairing the failed water pump, the standby water pump is started; after completing the water pump modification, the standby water pump is shut down, which is helpful for the cooling water supply of the air compressor 10.
