Ferry wheel circulating cooling water air bleeder

Technical Field

The utility model relates to a ferryboat field especially relates to ferryboat recirculated cooling water gas release device.

Background

During ship navigation, the diesel engine is cooled by a circulating water system, namely river (sea) water is absorbed by a water pump, and high-temperature internal circulating water is cooled by a heat exchanger. In the process, a large amount of bubbles generated by high-speed rotation of the ship propeller enter the system along with the ship propeller, and after the bubbles are accumulated to a certain degree, the river water pump generates an air suction fault, so that the water seal is damaged, and the ship must be stopped.

According to the utility model discloses an aspect provides ferryboat recirculated cooling water air bleeder, including the seabed valve case, river water filter and the river water pump that communicate in proper order, river water filter top is equipped with discharge valve.

Therefore, the ferry circulating cooling system is positioned below the river level, the internal pressure is higher than the normal atmospheric pressure, and after the exhaust valve is opened, the air gathered at the top of the river water filter in the circulating cooling system can be smoothly discharged, so that the suction phenomenon of a river water pump can be avoided, and the service life is prolonged.

In some embodiments: still include the return bend, return bend one end and discharge valve exit linkage, the other end sets up towards river water filter top perpendicularly. Therefore, the water sprayed from the exhaust valve is prevented from splashing everywhere.

In some embodiments: the exhaust valve is in threaded connection with the top of the river water filter through a threaded connector, and the threaded connector is a double-end external thread connector or an internal and external thread connector.

In some embodiments: still include the pressure gauge, the pressure gauge sets up in river water pump suction entrance. Therefore, the pressure of the river water pump suction inlet can be monitored, and when the pressure is smaller than a certain value, the exhaust valve is opened to exhaust.

In some embodiments: the water flow sensor and the pressure gauge are electrically connected with the controller. Therefore, automatic control can be performed, and manual monitoring and exhausting are not needed.

In some embodiments: the controller can set a preset pressure value, when the pressure measured by the pressure gauge is smaller than the preset pressure value, the controller controls the exhaust valve to be opened, and when the water flow sensor measures that water flows out, the controller controls the exhaust valve to be closed.

In some embodiments: a collecting barrel is arranged below the outlet of the elbow. Thereby enabling collection of water discharged from the discharge valve.

Drawings

Fig. 1 is a schematic structural view of the ferry circulating cooling water air bleeder of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the following description of the drawings.

As shown in fig. 1, the ferry circulating cooling water gas release device comprises a seabed valve box 1, a river water filter 2 and a river water pump 3 which are sequentially communicated, and an exhaust valve 4 is arranged at the top of the river water filter 2.

Still include

return bend

5, 5 one ends of return bend and 4 exit linkage of discharge valve, the other end sets up towards 2 tops of river water filter perpendicularly, sets up perpendicularly downwards promptly. In the present embodiment, the elbow 5 comprises a 90 ° elbow and a 90 ° faucet, the 90 ° faucet is connected to the 90 ° elbow, and the 90 ° elbow is connected to the exhaust valve 4. The bent pipe 5 can also be formed by welding two 90-degree bent pipes or integrally forming the two 90-degree bent pipes.

The exhaust valve 4 is in threaded connection with the top of the river water filter 2 through a threaded connector 6, and the threaded connector 6 is a double-end outer thread connector or an inner and outer thread connector. Preferably a double-ended external screw joint, without changing the flow of the venting valve 4.

Still include pressure gauge 7, pressure gauge 7 sets up in river water pump 3 suction inlet department. Therefore, the pressure of the river water pump suction inlet can be monitored, and when the pressure is smaller than a certain value, the exhaust valve is opened to exhaust. Through experiments, the pointer of the pressure gauge is-0.02 MPa under normal conditions, the vacuum pressure of the water circulation system is gradually reduced after the machine continuously operates for 24 hours along with the increase of the operating time of the river water pump, the pointer of the pressure gauge swings between-0.02 MPa and-0.1 MPa, the machine continuously operates for about 24 hours, and the river water pump is completely emptied when the pointer of the pressure gauge points to-0.1 MPa. Therefore, in this embodiment, when the pressure is less than-0.09 MPa, the exhaust valve is opened to perform the exhaust.

Still include controller 8 and rivers sensor 9, discharge valve 4 is the solenoid valve, and opening and closing of discharge valve 4 is controlled to controller 8, and controller 8 can fixed mounting on the lateral wall of water filter 2, and rivers sensor 9 and pressure gauge 7 all are connected with controller 8 electricity.

The controller 8 can set a preset pressure value, the preset pressure value in this embodiment is-0.09 MPa, when the pressure measured by the pressure gauge 7 is smaller than the preset pressure value, the controller 8 controls the exhaust valve 4 to open, when the water flow sensor 9 measures that water flows out, the controller 8 controls the exhaust valve 4 to close, the water flow sensor 9 can also set a preset value, when the measured water flow reaches the preset value, the controller 8 controls the exhaust valve 4 to close, and the control time of the exhaust valve is prevented from being influenced by the water flowing along the exhaust valve during the exhaust process.

In addition, a collecting barrel (not shown) is arranged below the outlet of the elbow pipe 5. Thereby enabling collection of water discharged from the discharge valve.

In conclusion, the ferry circulating cooling system is positioned below the river level, the internal pressure is higher than the normal atmospheric pressure, and after the exhaust valve is opened, the air gathered at the top of the river water filter in the circulating cooling system can be smoothly discharged, so that the phenomenon of suction of a river water pump can be avoided, and the service life is prolonged.

The above description is only one embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of similar modifications and improvements can be made without departing from the inventive concept, and these should also be considered as within the protection scope of the present invention.
