Background Technology

[0002] Currently, there are two common types of vacuum water priming devices: direct priming and constant-suspension vacuum priming. Direct priming requires waiting time for the priming process to complete; constant-suspension vacuum priming, when paired with a vacuum pressure stabilizing tank, is easily limited by the height of the installation environment and occupies a large area. Once the models of these two priming devices are determined, any changes in requirements later necessitate replacing the entire vacuum source device, resulting in high costs. Utility Model Content

Detailed Implementation

[0023] The preferred embodiments of this utility model are given below with reference to the accompanying drawings to illustrate the technical solution of this utility model in detail.

[0024] Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 for Figure 1 Enlarged view of point "A", Figure 3 for Figure 1 Enlarged view of section "B". (See image below.) Figure 1-3 As shown: This utility model proposes an automatic vacuum rapid water intake device, which includes: a vacuum source, an air extraction device, a main vacuum pipe, vacuum branch pipes, and an electrical control box. The main vacuum pipe is connected to multiple sets of vacuum branch pipes, and the vacuum source is connected to multiple sets of vacuum branch pipes through the main vacuum pipe. Each set of vacuum branch pipes is connected to an air extraction device, which is located on the pipe at the water inlet of the water pump.

[0025] A vacuum cylinder 12 is installed inside the vacuum source, and the vacuum cylinder 12 always maintains a set vacuum level.

[0026] The air extraction device includes an air extraction tank 17, and a vacuum branch pipe is connected to the connected air extraction device to extract air from the air extraction tank at any time. The air extraction tank 17 is equipped with a double float level switch 15 and an interlocking solenoid valve 16 for the water intake branch. The air extraction tank 17 automatically opens the solenoid valve 16 for water intake according to the configured double float level controller 15 to induce water and sends a water intake completion signal.

[0027] The electrical control box controls the entire automatic vacuum rapid water priming device, diagnoses faults, and displays the working status of each unit.

[0028] The vacuum source includes a vacuum pump 4, a vacuum cylinder 12, and a drain cylinder 13; the air extraction device includes an air extraction tank 17, with the main vacuum pipe installed between the vacuum cylinder 12 and the air extraction tank 17, and the air extraction tank 17 installed on the water intake branch. The air extraction tank 17 is equipped with a double float level switch 15 that is interlocked with the solenoid valve 16 of the water intake branch; the vacuum cylinder 12 is equipped with a vacuum pump 4 and a pressure switch 5; and the electrical control box 11 is installed on the vacuum cylinder 12.

[0029] The vacuum cylinder 12 of this utility model is equipped with a vacuum cylinder level switch 7, a one-way ball valve 8 and a balance valve 6, and a high and low level switch 9 and a one-way valve 10 are installed on the drain cylinder 13.

[0030] The application of this utility model mainly includes the following steps: 1. Selectively implement water diversion modes based on customer needs (taking the constant-hanging water diversion mode as an example).

[0031] 2. Turn on the electrical control box to put the system into standby mode.

[0032] 3. Turn on the vacuum pump and simultaneously open the solenoid valve of the water inlet branch to connect the vacuum tank and begin the vacuuming operation on the water pump and vacuum pipeline.

[0033] 4. By using the feedback signal from the dual float level switch of the air extraction tank, the solenoid valve of the water intake branch is opened and closed to maintain the liquid level of the air extraction tank between the high and low level switches.

[0034] 5. Stop the vacuum pump by setting the upper limit of the vacuum level using the vacuum cylinder pressure switch.

[0035] 6. During operation, the system automatically opens the check valve to drain sewage based on the height of the vacuum cylinder / drainage liquid; at the same time, it monitors the liquid level using the configured level switch to ensure safe, reliable and stable operation of the system.

[0036] by Figure 1-4 Taking this as an example, the control principle of the entire vacuum system will be explained in detail: 1. Automatic control principle of vacuum pump: The vacuum pump is automatically started and stopped based on the upper / lower limit values ​​of the pressure switch on the vacuum cylinder.

[0037] For example, the upper pressure limit inside the vacuum cylinder 12 is set to -80 kPa, and the lower limit is set to -40 kPa. When the vacuum level inside the vacuum cylinder is lower than the set lower limit, the pressure switch sends a feedback signal to the control box 11. Upon receiving the signal, the control box opens the working fluid solenoid valve 3, starts the vacuum pump 4, and the vacuum pump motor starts running to evacuate the vacuum. When the vacuum pressure inside the vacuum cylinder reaches the set upper limit, the pressure switch sends a feedback signal to the control box. Upon receiving the signal, the control box stops the vacuum pump and simultaneously closes the working fluid solenoid valve 3 and the balance valve.

[0038] 2. Working principle of the water pump air extraction tank: The water pump vacuum tank 17 is equipped with a dual float level switch 15 installed on the vacuum priming branch line equipped with a solenoid valve 16 and is higher than the highest priming point of the water pump. When priming is required, the solenoid valve of the priming branch line is opened to connect the vacuum tank and start vacuum priming of the water pump vacuum pipe and water pump chamber. As the system vacuum increases, when the liquid level in the vacuum tank reaches the high level, the solenoid valve of the automatic interlock branch line is closed, and a priming completion signal is fed back. At this time, depending on the priming mode selected by the customer, if the customer selects the direct priming mode, the vacuum pump is stopped after the priming completion signal is fed back, and the system priming is completed.

[0039] If the customer selects the constant priming mode, after the priming completion signal is received, the system will automatically enter the vacuum holding state. If the liquid level in the vacuum tank drops to the low liquid level switch position of the double float, the system will automatically open the solenoid valve of the priming branch, reconnect the vacuum source, and continue to prime water to the high liquid level switch position of the double float. This process is repeated to ensure that the liquid level in the vacuum tank is always maintained between the high and low liquid level switches of the double float.

[0040] 3. Working principle of the drain pipe: During system operation, the balance valve 6 is normally open and the vent valve 14 is normally closed, keeping the vacuum cylinder 12 and the drain cylinder 13 connected at all times. The liquid accumulated in the vacuum cylinder 12 flows into the drain cylinder through the one-way valve 8. When the high-level switch signal of the liquid level switch 9 in the drain cylinder is triggered, the balance valve closes and the vent valve opens. At this time, the vacuum in the cylinder is broken, and the accumulated liquid is drained through the one-way valve 10. Due to the one-way action of the one-way ball valve 8, the vacuum in the vacuum cylinder is almost unaffected, thus ensuring the continuous and stable operation of the vacuum pumping system.

[0041] 4. Electrical Control Principles according to Figure 4 As can be seen from the electrical control schematic diagram, this utility model provides a way to seamlessly switch between direct water intake and constant suspended water intake modes without changing the configuration of the on-site equipment.

[0042] When the customer selects the direct water intake mode, the system switches to the direct water intake mode. Based on the remote start signal, the system starts the vacuum pump 4, opens the water intake branch solenoid valve 16 to connect the vacuum tank 17 and starts vacuum water intake. When the high level switch signal of the double float level switch 15 in the vacuum tank is triggered, the water intake branch solenoid valve and the vacuum pump are closed. At the same time, a signal indicating that vacuum water intake is complete is fed back, and the water pump is started.

[0043] When the customer selects the constant priming mode, the electrical control system switches to the constant priming mode. The system automatically starts and stops the vacuum pump 4 according to the upper and lower limits set by the pressure gauge 5 of the vacuum cylinder electric contact, so that the system always maintains within the set pressure range. At the same time, the water pump suction tank 17 automatically opens and closes the priming branch solenoid valve 16 according to the high and low liquid level switch signals of the double float liquid level switch 15, so as to always ensure that the liquid level in the suction tank is stable between the high and low liquid level switches, thereby ensuring that the water pump can be started at any time.

[0044] During operation, the liquid accumulated in the vacuum cylinder is interlocked with the balance valve 6, vent valve 14, liquid level switch 7, high and low liquid level switch 9, and one-way ball valve 8 and one-way valve 10, which allows the system to drain water simultaneously while in vacuum mode without interfering with each other, thus greatly improving work efficiency.

[0045] This utility model integrates a traditional skid-mounted vacuum pump, vacuum tank, and steam-water separator into a single integrated water intake device, significantly reducing the equipment installation area and overcoming the limitations of traditional on-site installation height of the vacuum tank. The dual float level controller configured in the vacuum tank is specially designed to be unaffected by water wave fluctuations, and can seamlessly switch between direct water intake and constant suspension water intake modes without changing the on-site equipment, greatly meeting different on-site needs. In addition, during operation, the system cleverly utilizes the interaction between the balance valve, vent valve, level switch, and check valve installed on the vacuum tank and drain tank to achieve simultaneous vacuuming and drainage without interference, greatly improving work efficiency.

[0046] The basic principles, main features, and advantages of this utility model have been shown and described. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
