[0031] Example 1
[0032] Reference Figures 1-4 This embodiment provides an electric vacuum device for improving the efficiency of a self-priming pump, including a vacuum component 100 and a switching component 200.
[0033] The vacuum assembly 100 includes a transfer box 101, a vacuum pump 102, a self-priming pump 103, and a water pump 104. The vacuum pump 102, the self-priming pump 103, and the water pump 104 are respectively connected to the transfer box 101. Multiple self-priming pumps 103 are provided, one of which is used as a standby pump.
[0034] The switching assembly 200 includes a pressing member 201, a connecting plate 202, and a closing plate 203. The pressing member 201, the connecting plate 202, and the closing plate 203 are respectively installed on the transfer box 101. The pressing member 201 is rotatably connected to the connecting plate 202, and the connecting plate 202 is rotatably connected to the closing plate 203. Multiple pressing members 201, connecting plates 202, and closing plates 203 are provided.
[0035] The transfer box 101 includes a vacuum tube 101a, a water pump tube 101b, and a self-priming tube 101c. The vacuum tube 101a, water pump tube 101b, and self-priming tube 101c are respectively disposed on the four sides of the transfer box 101. The self-priming tube 101c is provided with multiple... Figure 3 As shown.
[0036] Vacuum pump 102 is connected to vacuum tube 101a, self-priming pump 103 is connected to self-priming pipe 101c, and water pump pipe 101b is connected to water pump 104.
[0037] The self-priming pipe 101c has a gas tank 101c-1 and a water tank 101c-2 on its side to separate the flow of gas and liquid.
[0038] The transfer box 101 also includes a connecting groove 101d, a vacuum block 101e, a water pump block 101f, a self-priming block 101g, and a connecting pipe 101h. The connecting groove 101d is located at the upper end of the transfer box 101, and the vacuum block 101e, water pump block 101f, self-priming block 101g, and connecting pipe 101h are located within the connecting groove 101d. Figure 3 Vacuum block 101e is connected to vacuum tube 101a, water pump block 101f is connected to water pump tube 101b, self-priming block 101g is connected to self-priming tube 101c, vacuum block 101e is connected to gas tank 101c-1 through connecting pipe 101h, and water pump block 101f is connected to water tank 101c-2 through connecting pipe 101h.
[0039] The transfer box 101 can be protected by a box body.
[0040] In use, valves are installed on the two self-priming pipes 101c. When the main vacuum pump 102 is started, the valves on the self-priming pipes 101c not connected to the main vacuum pump 102 are closed, and the vacuum pump 102 and the water pump 104 are turned on. The vacuum pump 102 extracts the gas in the main pipeline connected to the main self-priming pump 103 through the channel formed by the vacuum block 101e, the connecting pipe 101h, and the gas tank 101c-1. The water pump 104 injects water into the main pipeline connected to the main self-priming pump 103 through the water pump block 101f, the connecting pipe 101h, and the water tank 101c-2. Through the dual combination of vacuuming and water injection, the start-up time of the main self-priming pump 103 is reduced, and the main self-priming pump 103 can be quickly responded to.
[0041] When the main vacuum pump 102 malfunctions, close the self-priming pipe 101c connected to the main vacuum pump 102, open the valve on the other self-priming pipe 101c, and then start the vacuum pump 102 and the water pump 104 to accelerate the start-up speed of the standby vacuum pump 102.
[0042] Example 2
[0043] Reference Figures 1-5 This is the second embodiment of the present invention. Based on the previous embodiment, this embodiment provides an implementation method for an electric vacuum device that improves the efficiency of a self-priming pump.
[0044] The self-priming block 101g has a first sliding groove 101g-1 and a second sliding groove 101g-2 on its side. The first sliding groove 101g-1 is connected to the gas groove 101c-1, and the second sliding groove 101g-2 is connected to the water groove 101c-2.
[0045] The sealing plate 203 is provided with multiple sliding grooves 101g-1 and 101g-2 respectively, and the sealing plate 203 is slidably connected to the first sliding groove 101g-1 and the second sliding groove 101g-2 respectively.
[0046] The transfer box 101 also includes a limiting block 101i and a hollow column 101j. The limiting block 101i is located at the upper end of the self-priming block 101g, and the hollow column 101j is located in the connecting groove 101d. There are two limiting blocks 101i and hollow columns 101j symmetrically arranged along the center line of the transfer box 101.
[0047] The side of the limiting block 101i is provided with an upper limit slide groove 101i-1 and a lower limit slide groove 101i-2, with the upper limit slide groove 101i-1 located at the upper end of the lower limit slide groove 101i-2.
[0048] The upper end of the sealing plate 203 is provided with a sealing connecting post 203a, and the side of the sealing plate 203 is provided with a sealing spring 203b. The sealing spring 203b is placed in the first sliding groove 101g-1 and the second sliding groove 101g-2. The sealing connecting post 203a is inserted into the first sliding groove 101g-1 and the second sliding groove 101g-2. The sealing connecting post 203a is hinged to the connecting plate 202.
[0049] The pressing component 201 includes a rotating baffle 201a, a movable column 201b, and a pressing block 201c. The rotating baffle 201a is rotatably connected to the movable column 201b, and the movable column 201b is slidably connected to the pressing block 201c. The pressing block 201c is inserted into the hollow column 101j.
[0050] The lower end of the movable column 201b is provided with a movable slider 201b-1, and the side of the pressing block 201c is provided with a pressing sliding groove 201c-1, and the movable slider 201b-1 is placed in the pressing sliding groove 201c-1.
[0051] The side of the pressing block 201c is also provided with a pressing connecting rod 201c-2, which is rotatably connected to the connecting plate 202. The lower end of the pressing block 201c is provided with a pressing spring post 201c-3, which is inserted into the hollow column 101j and fixedly connected to the interior of the hollow column 101j.
[0052] The rotating baffle 201a is provided with a limit stop 201a-1 on its side, and the limit stop 201a-1 cooperates with the upper limit slide groove 101i-1 and the lower limit slide groove 101i-2.
[0053] When the device is not in use, the two limit blocks 201a-1 in the transfer box 101 are placed in the upper limit slide groove 101i-1. At this time, the rotating baffle 201a cannot be pressed down, and the moving slider 201b-1 is simultaneously located in the lowering slide groove 201c-1 of the two lowering blocks 201c, to prevent the two lowering blocks 201c from moving down after accidental contact. At this time, the four sealing plates 203 close the first slide groove 101g-1 and the second slide groove 101g-2 on the two self-priming blocks 101g. The gas groove 101c-1 and the water groove 101c-2 on the self-priming pipe 101c are isolated from the self-priming block 101g.
[0054] In use, there is no need to install valves on the two self-priming pipes 101c. When the main vacuum pump 102 needs to be started, rotate the rotating baffle 201a to move the limit block 201a-1 out of the upper limit slide groove 101i-1. The sliding block 201b-1 slides to the lower pressure slide groove 201c-1 on the lower pressure block 201c associated with the main vacuum pump 102. Then press the rotating baffle 201a. The rotating baffle 201a moves downward, causing the connecting plate 202 to move. The connecting plate 202 causes the sealing connecting column 203a to move, thereby causing the sealing plate 203 to slide in the first sliding groove 101g-1 and the second sliding groove 101g-2, opening the gas groove 101c-1 and the water groove 101c-2. The sealing spring 203b is compressed and deformed, and the lower pressure spring column 201c-3 is compressed and deformed. When the rotating baffle 201a is pressed to a certain position... Rotate the rotating baffle 201a to make the limiting block 201a-1 enter the lower limiting slide groove 101i-2 to restrict the position of the rotating baffle 201a. At this time, the gas tank 101c-1 and the water tank 101c-2 are in a fully open state. It should be noted that the self-priming pipe 101c connected to the standby vacuum pump 102 is in a closed state at this time. Then, start the vacuum pump 102 and the water pump 104. The vacuum pump 102 extracts the gas in the main pipe connected to the main self-priming pump 103 through the channel formed by the vacuum block 101e, the connecting pipe 101h and the gas tank 101c-1. The water pump 104 injects water into the main pipe connected to the main self-priming pump 103 through the water pump block 101f, the connecting pipe 101h and the water tank 101c-2. Through the dual combination of vacuuming and water injection, the start-up time of the main self-priming pump 103 is reduced, and the main self-priming pump 103 can be quickly responded to.
[0055] When a malfunction occurs, rotate the rotating baffle 201a to move the limit block 201a-1 out of the lower limit slide groove 101i-2, and then return to the unpressed state. Slide the moving slider 201b-1 into the lower pressure slide groove 201c-1 on another lower pressure block 201c and repeat the above actions until the limit block 201a-1 is placed back into the limit slide groove 101i-2. Then turn on the vacuum pump 102 and the water pump 104 to quickly start the standby self-priming pump 103.
[0056] When the main self-priming pump fails, this device can quickly switch to and start the backup pump, reducing waiting time. The switching method is simple and fast. During routine maintenance of the two self-priming pumps, it can also be flexibly switched, basically enabling uninterrupted operation and improving work efficiency.
