Abstract
A diaphragm type sea water pump comprises a machine frame. A motor, a reduction gearbox and a diaphragm type water pumping mechanism are arranged on the machine frame. A diaphragm of the diaphragm type sea water pump separates sea water from transmission mechanical components. Simultaneously, a seam between a front housing and a rear housing is sealed so that a sealing effect is good. Simultaneously, corrosion of the sea water on water pump moving components is avoided, the service life of the water pump is prolonged, and the water pump is not required to be filled with water and is free of limits of use conditions. A rubber layer covered on the surface of a sealing ball improves a sealing effect of a connector between a water drawing pipe and an opening and closing cavity in a water pumping process, and the water pumping performance is improved.

At present carrying out the extraction operation of seawater, mainly be to use the water pump of conventional construction, traditional water pump is to utilize the operation of drawing water of motor driving water wheels, water wheels and contact with sea water, make water wheels be subjected to seawater corrosion easily, be mixed with a large amount of particulate materials such as silt in the seawater, cause the wearing and tearing of water wheels easily, even break the blade of water wheels, and the rate of corrosion of water wheels, the working life of having reduced water pump have further been accelerated in wearing and tearing, and the main shaft of motor need carry out the axle envelope, seawater also can cause the corrosion of axle envelope the leakage of seawater, even cause the damage of motor.
Summary of the invention
The present invention is directed to and carry out the water pump that seawater extracts at present, easy to wear and corrosion, aging speed is fast, leaks easily, damages problems such as motor, has designed a kind of diaphragm type sea water pump.
Diaphragm type sea water pump of the present invention, comprise frame, motor is installed on the frame, speed reducer, the barrier film mechanism of drawing water, the motor driving speed reducer, on the output shaft of speed reducer setting eccentric wheel is installed, be set with a rocking arm on the eccentric wheel, the barrier film mechanism of drawing water comprises the aqueduct of vertical setting, relative front end-cover and the rear casing of installing, between front end-cover and the rear casing barrier film is installed, the rear casing rear end is provided with conduit, is slidingly fitted with piston rod in the conduit, and the front end of conduit is connected with diaphragm center, the rear end of conduit and the front end of rocking arm are hinged, the front portion of front end-cover is communicated with the middle part of aqueduct, the top of aqueduct, the bottom is respectively arranged with water outlet, water inlet, the upper and lower of aqueduct all are provided with the logical chamber of closing, logical closing all is equipped with a ball sealer in the chamber, the logical top of closing the chamber all is equipped with the baffle plate that is provided with through hole.
Preferably, the surface coverage of ball sealer has rubber layer.
Preferably, the diameter of ball sealer is greater than the twice of aqueduct internal diameter.
Preferably, logically close the internal diameter in chamber greater than the twice of ball sealer diameter.
The invention has the beneficial effects as follows: the barrier film of diaphragm type sea water pump separates the mechanical part of seawater with transmission, simultaneously with the gap sealing between front end-cover and the rear casing, good sealing effect, avoided the corrosion of seawater for the water pump moving element simultaneously, prolonged the working life of water pump, and water pump does not need water, the restriction of no service condition, the rubber layer that covers the ball sealer surface has strengthened aqueduct and the logical sealing effect that closes the connection mouth place in chamber in the pump process, has improved the performance of drawing water.
Description of drawings
Embodiment
Diaphragm type sea water pump of the present invention as shown in Figure 1, comprises frame 1, and motor 2, speed reducer 3, the barrier film mechanism 4 of drawing water is installed on the frame 1.Motor 2 drives speed reducer 3, on the output shaft 5 that speed reducer 3 arranges eccentric wheel 6 is installed, and is set with a rocking arm 7 on the eccentric wheel 6.
The barrier film mechanism 4 of drawing water comprises the aqueduct 8 of vertical setting, relative front end-cover 9 and the rear casing of installing 10, between front end-cover 9 and the rear casing 10 barrier film 11 is installed, rear casing 10 rear ends are provided with conduit 12, be slidingly fitted with piston rod 13 in the conduit 12, the front end of conduit 12 is connected with barrier film 11 centers, the front end of the rear end of conduit 12 and rocking arm 7 is hinged, the front portion of front end-cover 9 is communicated with the middle part of aqueduct 8, the top of aqueduct 8, the bottom is respectively arranged with water outlet 14, water inlet 15, the upper and lower of aqueduct 8 all is provided with the logical chamber 16 of closing, logical closing all is equipped with a ball sealer 17 in the chamber 16, the logical top of closing chamber 16 all is equipped with the baffle plate 18 that is provided with through hole.
The surface coverage of ball sealer 17 has rubber layer, and the diameter of ball sealer 17 leads to and closes the internal diameter in chamber 16 greater than the twice of ball sealer 17 diameters greater than the twice of aqueduct 8 internal diameters.
During original state, two ball sealers 17 are because gravity, all drop on logical closing on 16 bottoms, chamber and the opening that aqueduct 8 links to each other.
During work, motor 2 drives eccentric wheel 6 by speed reducer 3, makes eccentric wheel 6 drive piston rod 13 to-and-fro motion in conduit 12 by rocking arm 7, and the water pipe that is connected water inlet 15 stretches in the seawater.
Piston rod 13 pulling barrier films, the pressure in the front end-cover 9 increase, and the ball sealer 17 on top is subjected to outside inside pressure and the gravity of self, is pressed on logical closing on the opening of 16 bottoms, chamber, with the opening sealing, makes and logically closes chamber 16 and be in closed condition; The outside inside pressure that the ball sealer 17 of bottom is subjected to overcomes the gravity of himself, ball sealer 17 is removed from the logical opening that closes 16 bottoms, chamber, opening is opened, make and logical close chamber 16 and be in open mode, seawater is subjected to outside inside pressure, closes chamber 16 along water inlet 15, aqueduct 8, bottom logical successively and enters in the water containing chamber body of front end-cover 9 and aqueduct 8 middle parts forming.
Piston rod 13 promotes barrier films, and the outside pressure in inside that the ball sealer 17 on top is subjected to overcomes the gravity of himself, and ball sealer 17 is removed from the logical opening that closes 16 bottoms, chamber, and opening is opened, and makes logically to close chamber 16 and be in open mode; The ball sealer 17 of bottom is because the gravity of self and water, fall logical closing on the opening of 16 bottoms, chamber after rise to its pressure, opening is closed, make and logical close chamber 16 and be in closed condition, the seawater in the water containing chamber body is successively along logical chamber 16, the aqueduct 8 of closing on top, flow out from water outlet 14, finish the operation of drawing water.
