Abstract
The utility model relates to a hand self-suction pump which belongs to a liquid switching apparatus. The utility model is suitable for switching liquid among opening containers with liquid level difference, and the liquid switching apparatus can be used for the switching of the liquid of which the kinematic viscosity is 7.0*10<-6 >m< 2 >/s at the temperature of 20 DEG C. The utility model has no power source, continuous liquid stream, no liquid leaking and favorable shutting, and the utility model is mainly characterized in that a liquid stream lead mouth is positioned within the effective stroke of a piston.
Description
The utility model belongs to a kind of liquid changeover apparatus.
Before the utility model is made, switching of liquid between container often arranged in daily life and the industry, present employed kinetic pump not only complex structure, volume weight is big, and can not adapt to the occasion of energy free and condition strictness.Motorless oil extractor exists the shortcoming that liquid stream is discontinuous, time-consuming, consume power again; And the one end is inserted in the open containers of holding liquid with a flexible pipe, the other end is with after mouthful inhaling, and utilizes hydraulic difference to insert the liquid into the method for another container again, or the suction deficiency, or suction is excessive, and easily with in the fluid intake, and the closing property of liquid stream is bad.
The purpose of this utility model provides a kind of motorless manual self-priming pump, and it can be finished between container liquid and switch and control, and avoids in the fluid intake.
Realization of the present utility model, be the degree of vacuum that causes when from one end to the other side moving by piston, liquid is sucked in the cylinder body, when piston continues motion, and make when liquid communicates in outage and the cylinder, rely on two liquid levels of switching container poor, liquid is switched to another container from a container by the suction principle.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the sectional drawing according to the manual self-priming pump that the utility model proposes.
Describe the details and the working condition of the concrete device that the utility model proposes in detail below in conjunction with accompanying drawing.
The utility model mainly contains that 1. the suction that is used to connect pick-up tube chews, seal washer 2., cylinder body 3., the piston of band soft seal 4., end cap 5. and the liquid stream that is positioned at the piston effective travel draw and chew 6. composition.State when being illustrated as drainage.After single-rod piston pushes along the diagram direction of arrow.This manual control self-priming pump is closed condition.
Chew 1. in the suction that the single-rod piston cylinder body does not have an end of piston rod to load onto pick-up tube, seal washer 2. with the flexible pipe (not shown), and piston 4. be positioned at cylinder body 3. the other end draw near piston rear end one side and chew 6..After the pipetting hose of this manual control self-priming pump being put into the liquid of being inhaled container, piston is 4. by being pulled to end cap near pick-up tube one end 5. during an end, just 4. the piston that connects pick-up tube forms certain degree of vacuum in the chamber, cause like this and inhaled the atmospheric pressure that bears on the liquid level in the container and be higher than the 4. pressure in the chamber of piston, under this differential pressure action, sucked liquid is all drawn continuously along being lower than the liquid outlet of being gone to the bottom by the suction container, closes liquid stream and only need push back piston 4..
The utility model is applicable to that the liquid between the open containers with liquid level difference switches, and kinematical viscosity is 7.0 * 10 when being particularly useful for 20 ℃
-6m
2The liquid that/s is following.
The utility model does not consume energy, and aspiration drainage and closing motion are simple, only needs one to push away one and draw, and because of it has the property of closing, can accomplish that also liquid switches aneroid and leak.
Claims (3)
1, manual self-priming pump is a kind of liquid changeover apparatus, and the liquid that is used to have between the open containers of liquid level difference is switched, it is characterized in that this pump by suction chew 1., cylinder body 3., single-rod piston 4. and draw to chew 6. and form, draw to chew and 6. be positioned at piston effective travel 4..
2, manual self-priming pump according to claim 1 is characterized in that cylinder body internal diameter 3. is between 10~100mm.
3, manual self-priming pump according to claim 1 is characterized in that drawing and chews that 6. to be positioned at piston effective travel 4. be 40~150mm.
