Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical solution of the present invention, the following description is made by using specific examples.
Only portions related to the embodiments of the present invention are shown for convenience of explanation.
Referring to fig. 1-4, the self-priming system includes a water inlet pipe 2, a water outlet pipe 3 and a self-priming device 1, a plurality of sets of water pump units 4 are connected in parallel between the water inlet pipe and the water outlet pipe, the self-priming device 1 includes a spray pipe 11 and a water storage device 12, an air inlet pipe 5 is arranged at an air inlet end of the spray pipe, an air outlet pipe 6 is arranged at an air outlet end of the spray pipe, a first electromagnetic valve 7 is arranged on the air inlet pipe, air inlets of the water storage device are connected to the water outlet end of each water pump unit one by one, and an air outlet of the water storage device is connected to a negative pressure end of the spray pipe through a second electromagnetic valve 8.
This device mainly is applied to on the ship, but not only is limited to the steamer, because of the ship water tank all is located the bottom, when the working shaft does not inhale the ability from inhaling, water can't inhale the working shaft, this from inhaling the device mainly adopts the mode of injection drainage to inhale each working shaft through the inlet tube with the water in the water tank to guarantee that the working shaft is full of water in inlet channel and the water pump when the start, in order to ensure that the water pump can normally provide the water for the outlet pipe. And the self-priming device is operated only when the water supply pump is restarted after power failure.
The self-suction device is designed and manufactured according to the principle of the Venturi effect. The principle of the venturi effect is that when wind blows over an obstacle, the air pressure is relatively low near the port above the lee side of the obstacle, creating an adsorption effect and causing a flow of air. The venturi principle is simple in that the gas flow is reduced from a larger size to a smaller size to increase the gas flow rate, so that the gas forms a "vacuum" region at the rear side of the venturi outlet. When the vacuum area is close to the workpiece, a certain adsorption effect is generated on the workpiece.
Specifically, the method comprises the following steps: in this embodiment, the spray tube is venturi, compressed air gets into from the intake pipe, discharge through the very little inside spray tube in cross-section, the cross-section reduces gradually along with it, compressed air's pressure increase, the velocity of flow also grows thereupon, the negative pressure end of spray tube can produce continuous negative pressure this moment, and then realize extracting the gas in the water receiver, just at this moment produce the vacuum in the water receiver, make with the air in the water pump set sucked the water receiver, then get into the spray tube, along with compressed air along with discharge from the spray tube, make the water pump realize from the effect of inhaling, after opening the water pump, water in the inlet tube can be inhaled water pump set place pipeline fast, get into the outlet pipe.
The bottom of the reservoir is connected to the inlet pipe by a branch pipe 9. The self-suction device not only enables air in the water pump unit to be sucked into the water storage device, but also enables air and water at the front end of the water pump unit to be sucked into the water storage device through the branch pipe, and a pipeline system at the rear end of the water inlet is in a negative pressure state. The whole pipeline system can achieve the self-suction effect when water supply is needed.
As a preferable structure, a control electromagnetic valve 14 is also arranged between the water outlet end of each set of water pump unit and the air inlet of the water storage device. When the water pump unit finishes self-priming operation and one of the water supply pumps runs normally, the control electromagnetic valve can effectively avoid forming a closed loop with other water pumps to influence the normal running of the water supply pump.
Further as a preferred structure, the self-priming device further comprises a box body 13, two arch-shaped installation seats 10 are arranged in the box body, and a first electromagnetic valve and a second electromagnetic valve are correspondingly fixed on the arch-shaped installation seats.
The first electromagnetic valve and the second electromagnetic valve are installed in the box body through the corresponding arched installation seats one by one, the stability of the self-suction device is improved, the first electromagnetic valve mainly controls the on-off of the air inlet pipe, and the first electromagnetic valve mainly controls the on-off of the air outlet of the water storage device and the negative pressure end of the spray pipe.
The water pump unit comprises a water pump 17, a ball valve 15 and a check valve 16 which are connected in sequence. Each water pump can work independently and simultaneously and is not interfered mutually. When any one of the water pumps needs to be closed, the ball valve and the check valve can be closed only by closing the water pump.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
