Abstract
The utility model relates to a gas and liquid pump which comprises a pump body (1), a gas distributing seat (3), a valve seat plate (2), and a pump shaft (11). A gas inlet connecting head (5) and a gas discharge connecting head (4) are arranged on the gas distributing seat, and a gas inlet valve sheet and a gas discharge valve sheet are arranged on the valve seat plate. Two cylinder sleeves (8), two pistons (9) and also a cam (10) with an inclined end face and an equal ratio lever (13) are arranged in the pump body, and through the relevant control to the pistons by the cam and the equal ratio lever, the two pistons are driven to make reciprocating motion to make pimping or pressing action by turns. As a result, the utility model can be used as a compressor as well as a vacuum pump and can pump and press liquids as well as gases.
Description
The utility model relates to a kind of reciprocating motion type pump structure.
The reciprocating motion type pump is common past dbl act compressor, axial piston pump etc.Past dbl act compressor utilizes connecting rod to promote reciprocating motion of the pistons and works.Axial piston pump then utilizes swash plate, backhaul dish and crawler shoe that plunger is promoted back and forth and works.
The purpose of this utility model provides a kind of new Gas-liquid pump structure.
This Gas-liquid pump comprises the pump housing, distribution seat and seat board.Air input joint and exhaust joint are housed on the distribution seat, air-intake valve plate and exhaust valve plate are arranged on the seat board, cylinder liner and piston are arranged in the pump housing, the piston plug is in cylinder liner.It also comprises the cam and a geometric ratio lever of an end slope, cam is loaded in the pump housing, cylinder is with two, piston also is two, the head of piston has a spherical surface hill, the inclined end face of cam is pressed on the head of piston, and the two ends of geometric ratio lever and the center of piston are slide hinged mutually by a lateral pin, and the middle part of geometric ratio lever is supported on the pump housing.
This Gas-liquid pump is owing to adopted the synkinetic driving mechanism of the relevant control with the geometric ratio lever of cam, work as cam rotation, when the inclined end face of cam is pressed into a piston in the cylinder liner, this piston is transferred to another piston by the transmission of geometric ratio lever in another cylinder liner, be close on the cam face, realized the to-and-fro motion of piston, two pistons aspirate or the pressure action in turn.Both can be used as compressor and used, and also can be used as vacuum pump and use.Press liquid can be taken out, also the body of calming the anger can be taken out.
Accompanying drawing 1 is the outline drawing of this Gas-liquid pump;
Accompanying drawing 2 is the A-A sectional view of Fig. 1 middle pump body part;
Accompanying drawing 3 is the B-B sectional view of Fig. 1;
Accompanying drawing 4 is a kind of structural drawing of exhaust joint.
As shown in Figure 1, (1) is the pump housing, and (2) are seat board, and (3) are the distribution seat, and air input joint (5) and exhaust joint (4) are contained on the distribution seat.
As shown in Figure 2, two cylinder liner (8) and two pistons (9) are arranged in the pump housing, the piston plug is in cylinder liner, and this two-piston also can be a plunger.The end face of cam (10) tilts.The center of cam is connected with the end of motor shaft (11).The head of piston (9) has spherical surface hill (6), and the end face of the inclination of cam is pressed on the head of piston.During cam rotation, the head of piston slides along cam face.The spherical surface hill of piston crown (6) also can be made an independent rotating semi-round ball, and the plane of semi-round ball contacts with the inclined-plane of cam, can make unit area stressed less like this.(13) be the geometric ratio lever, the center of its two ends and piston is slide hinged mutually by lateral pin (7), and lateral pin can be that face contacts with the geometric ratio lever, to improve stress.The middle part of geometric ratio lever is supported on the pump housing.Work as cam rotation, when one of them piston was pressed in cylinder liner, another piston whenever turned around because the interlock effect of geometric ratio lever is pulled out in cylinder liner, and just each passes in and out once each piston in cylinder liner.When a piston was in power stroke, another piston was in the preparation stroke, compared with single cylinder liner, piston structure, and volume just can be done lessly, and the pressure ratio of output is more steady, is particularly suitable for doing breadboard micropump.(12) are plane bearing among the figure.
Fig. 3 has represented the seat board that matches with this twin-tub structure and the structure of distribution seat, two air-intake valve plates (15) and two exhaust valve plates (16) are arranged on the seat board, an air-intake valve plate and an exhaust valve plate are one group, match with one group of cylinder liner (8), piston.In the middle of the distribution seat dividing plate (18) is arranged, the distribution seat is divided into two Room, i.e. suction chamber (14) and exhaust chamber (17).The air inlet position of two cylinder liner is in suction chamber (14), and the exhaust port of two cylinder liner is in exhaust chamber.Air input joint (5) is contained on the wall of suction chamber.Exhaust joint (4) is contained on the wall of exhaust chamber.Can also load onto a vacuum gauge and pressure gauge respectively on the sidewall of suction chamber and exhaust chamber, in order to the working state of indication pump.Can also adorn a safety valve on the exhaust chamber, in order to avoid when doing the compressor use, overpressure.
As shown in Figure 4, exhaust joint (4) can also be a small-sized gas towards pump, it has a nozzle (19), a pump port (21) and an outlet (22), pump port (21) can be blocked with a screw (20) at ordinary times, this exhaust joint is general joint.Screw (20) is taken off, exhaust joint becomes a gas towards pump, can be used as pollution discharge pump uses: pump port is connect drain pipe, start Gas-liquid pump, pressurized air forms certain suction force exhaust joint when nozzle (19) sprays, to extract out from sewage or dirty gas that drain pipe comes, discharge from outlet (22).Because gas is simple towards pump structure, thereby be difficult for stopping up, even can aspirate the material that has solid particle.
Air input joint (5) also can be made an air-strainer, and the air that enters pump like this is through filtering the life-span that can improve Gas-liquid pump.
