Description
Technical field
The utility model belongs to pump technical field of auxiliary equipment, relates to a kind of negative pressure pump automatic water diversion device.
Background technique
Need before pump startup to fill water, because centrifugal pump only could by centrifugal action in liquid during vane rotary under the condition of filling water, liquid obtains energy by centrifugal force, produces flow velocity and lift, the effect of competence exertion water pump Liquid transfer.Need to fill water to pump case and thin conduit road before starting mode of pump and could start water pump, water leading cylinder solves before centrifugal pump starts and fills with water problem.The effect of water pump water leading cylinder utilizes in cylinder the condition realizing having water, filled in advance by water pump, ensures that water pump starts in time.The water pump that existing negative pressure portable engine drives, the diversion mode taked is inflator shape hand push-pull type scuttlebutt, needs personnel to carry out diversion in pump before starting the machine, not only waste of manpower, material resources, and is not easy to automatic control.
Model utility content
The purpose of this utility model is to provide a kind of negative pressure pump automatic water diversion device, to realize automatic water-leading, simplifies operating procedure and technical difficulty, alleviates the labor intensity of operator.
The technical solution of the utility model is: negative pressure pump automatic water diversion device, comprises upper casing, lower casing and diaphragm.Upper casing is provided with into water suction port and water outlet air outlet, and lower casing is provided with negative port.Diaphragm is between upper casing and lower casing, and upper casing and lower casing are screwed, and diaphragm will be divided into upper shell-space and lower shell-space in water diversion apparatus.Upper shell-space is provided with air inlet water feeding one-way valve and water one-way valve of giving vent to anger out, and air inlet water feeding one-way valve is connected with water inlet suction port, and water outlet outgassing nonreturn valve is connected with water outlet air outlet, and lower shell-space is communicated with negative port.Water inlet suction port is connected with the diversion interface of negative pressure pump by water pipe, and negative port is connected with the crankcase negative port of negative pressure pump by tracheae.
Water pipe and tracheae are rubber pipe, pvc pipe or around property Stainless Steel Tube.Diaphragm is stainless steel diaphragm.Diversion interface is equipped with one-way valve.
Be negative pressure state lower than the atmospheric of the external world because of pump entrance place when water pump is started working, the diversion suction interface of the ingress of pump being arranged, an one-way valve realizes to bleed in pipeline, can realize again that oppositely turning off prevents from leaking gas from here simultaneously and enter in pump affecting soaking effect, and the function of auto switching under realizing prosthetic intervention situation.Successful, step reduces, and the operation of whole pump is simpler.
The utility model negative pressure pump automatic water diversion device can realize automatic water-leading, simplify operating procedure and technical difficulty, alleviate the labor intensity of operator, ensure that just negative pressure takes water pump successful use under emergency conditions, layman also can start machine smoothly and realize water pump pressurization water outlet fast.Achieve diversion automatically control owing to having installed one-way valve at diversion interface.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.The utility model protection domain is not limited to embodiment, and those skilled in the art make the scope that any change also belongs to the utility model protection in the scope that claim limits.
The utility model negative pressure pump automatic water diversion device as shown in Figure 1, comprises upper casing 2, lower casing 4 and diaphragm 3.Upper casing is provided with into water suction port 1 and water outlet air outlet 6, and lower casing is provided with negative port 5.Diaphragm is between upper casing and lower casing, and upper casing and lower casing are fixed by screw 10, and diaphragm will be divided into upper shell-space and lower shell-space in water diversion apparatus.Upper shell-space is provided with air inlet water feeding one-way valve and water one-way valve of giving vent to anger out, and air inlet water feeding one-way valve is connected with water inlet suction port, and water outlet outgassing nonreturn valve is connected with water outlet air outlet, and lower shell-space is communicated with negative port.As shown in Figure 2, water inlet suction port is connected with the diversion interface 7 of negative pressure pump by water pipe 12, and negative port is connected with crankcase negative port 8 by tracheae 11.Water pipe 11 and tracheae 12 are pvc pipe, and diaphragm is stainless steel diaphragm.Diversion interface 7 is equipped with one-way valve.
The power source of automatic water diversion device is the positive/negative-pressure fluctuation in engine crankcase, and being malleation in crankcase during descent of piston, is negative pressure during piston stroking upward.This pressure wave alternately changed is relied on to drive the diaphragm of airtight automatic water diversion device to move up and down.Due to air inlet water feeding one-way valve and the water one-way valve effect of giving vent to anger out of upper shell-space, one-in-and-one-out, realizes pump gas or pump water function.The entrance of automatic water diversion device is connected with water pump inside through PVC hose, the suction sleeve of water pump is placed in water, pilot engine, positive/negative-pressure in crankcase is relied on to drive the motion of membrane of automatic water diversion device, progressively the air in water pump pump case is drained, automatic precipitation promotes to be put in pump case, reaches the function of automatic water-leading.Achieve diversion automatically control owing to having installed one-way valve at diversion interface, automatically complete the control of through and off.In diversion process, first rely on negative pressure scuttlebutt to be extracted out by the air in pump case and suction sleeve, need to close this passage after emptying air draws full water.
