Description
(1) technical field
The utility model relates to a kind of centrifugal water pump, particularly a kind of diversion centrifugal water pump of exempting from.
(2) background technique
Existing centrifugal water pump is wanted earlier water in the water pump pump chamber before work, could work so that reach vacuum state in the pump chamber, and is so not only time-consuming but also require great effort, if water pump cannot proper functioning so just the operational area there is not diversion in advance.
(3) summary of the invention
The utility model has overcome above the deficiencies in the prior art, and it is a kind of time saving and energy saving, easy to operate to aim to provide, thus do not have that diversion can make also that the water pump pump chamber reaches that vacuum state can proper functioning exempt from the diversion centrifugal water pump.
The diversion centrifugal water pump of exempting from of the present utility model, a kind of diversion centrifugal water pump of exempting from, it comprises the pump housing, water pump spindle, impeller, belt pulley, water intake and water outlet, be communicated with a venting gas appliance on the described pump housing, described venting gas appliance comprises a cylinder, cylinder head, piston, connecting rod, have pump chamber intakeport that has one-way valve that communicates with pump housing inner chamber and the cylinder exhaust port that has one-way valve on the cylinder head, the connecting rod lower end is with an excentric sleeve, and a side of excentric sleeve has one to be fixed on the clutch that makes its move left and right on the water pump spindle by handle.
The diversion centrifugal water pump of exempting from of the present utility model is connected with a transparent water tumbler between pump chamber intakeport and the pump chamber.
The diversion centrifugal water pump of exempting from of the present utility model, clutch and handle, at its lower end contact segment are that a cross section is the circular groove of U-shaped, handle, at its lower end is spherical, gets back to initial position in order to make handle automatically after released, and there is a release spring joint of the handle and the pump housing.
Beneficial effect of exempting from the diversion centrifugal water pump of the present utility model is: (1) water pump also can make the water pump pump chamber reach vacuum state when not having diversion, thereby makes the water pump proper functioning; (2) simple in structure, easy to operate, time saving and energy saving.

(5) embodiment
Below in conjunction with the drawings and specific embodiments water pump of the present utility model is done concrete description:
Water pump of the present utility model comprises that it comprises the pump housing, water pump spindle, impeller, belt pulley, water intake and a water outlet, also is fixed with a venting gas appliance on the described pump housing.
In the accompanying drawings: the venting gas appliance of water pump of the present utility model comprises that one is fixed on the cylinder 9 on the pump housing 1 of water pump, be fixed with a cylinder head 12 above the cylinder 9, the cylinder exhaust port 11 that all has a pump chamber intakeport 13 that communicates with pump chamber above the cylinder head 12 and communicate with atmosphere, all be fixed with one-way valve in pump chamber intakeport 13 and the cylinder exhaust port 11, the pump chamber intakeport is externally connected to a water tumbler, between cylinder head 12 and the cylinder 9 seal washer is arranged, one piston 10 is arranged in the cylinder 9, the lower end of piston 10 is connected with a connecting rod 14, the other end of connecting rod 14 is with an excentric sleeve 5, it in the excentric sleeve 5 water pump spindle 2, one roll adjustment axle sleeve 4 is arranged between the bearing 3 on excentric sleeve 5 left sides and the water pump spindle 2, be connected with clutch 6 on the water pump spindle 2 on the right side of excentric sleeve 5, clutch 6 is connected for flat key with water pump spindle 2, the cross section of clutch 6 is in the annular groove of U-shaped one handle 8 to be arranged, and the lower end of handle 8 is positioned at the part of U-shaped groove of clutch 6 for spherical.Handle 8 has a release spring 7 with the joint of the pump housing 1.
Using method of the present utility model is: start the motor or the diesel engine that drive water pump operation, pump chamber this moment and atmospheric isolation, at this moment clutch 6 is in separated state with excentric sleeve 5, so at this moment connecting rod 14 and piston 10 do not move, has only clutch 6 to rotate with pump shaft 2 like this; When treating that water pump operation is steady, press lower handle 8, clutch 6 moves to excentric sleeve 5 under the promotion of handle 8 gradually, when clutch 6 with after excentric sleeve 5 combines, excentric sleeve 5 just can rotate together in water pump spindle 2, the motion drivening rod 14 of excentric sleeve 5 and piston 10 motions, when piston moves downward, cylinder block gas port 11 internal check valves cut out, the one-way valve of pump chamber intakeport 13 is opened, so 9 in cylinder is air-breathing in the pump chamber, when piston 10 moves upward be, cylinder block gas port 11 internal check valves are opened, the closed check valve of pump chamber intakeport 13, so at this moment the air in the cylinder 9 is only discharged from cylinder block gas port 11, along with the to-and-fro motion of piston 10, just constantly air-breathing and exhaust of cylinder 9, make the air in the pump chamber fewer and feweri, water increases gradually in the pump chamber, is full of whole pump chamber at last, thereby makes pump chamber reach vacuum, have water generates in the water tumbler that pump chamber links to each other simultaneously, at this moment release handle 8, and handle 8 is got back to original state under the effect of release spring 7, move right thereby drive clutch 6, separate with excentric sleeve 5 at last, excentric sleeve 5 stop motions make connecting rod 14 and also stop motion of piston 10, and cylinder 9 stops suction and exhaust, the centrifugal water pump proper functioning.
