Abstract
The utility model relates to a big flow multifunctional diaphragm type vacuum pump, which comprises a casing and a drive motor. The utility model is characterized in that the drive motor is arranged on one end of the casing, and the output end of the drive motor is connected with one end of a crank shaft, the other end of which is matched with a bearing that is arranged on the other end of the casing; at least two sets of symmetrical connecting rods are arranged on the crank shaft and are respectively connected with two diaphragm pumps which are respectively arranged on two symmetrically surfaces of the casing. The utility model can complete more than two pump suction and pump press processes by rotating one circle. The diaphragm pumps are symmetrically arranged. Therefore, the utility model has the advantages of high work efficiency, uniform stress, stable operation, reduced vibration, simple and compact structure, and small size, and can not only be used as a vacuum pump, but also be used as a conveying pump.
Description
Technical field
The utility model relates to diaphragm pump, is specifically related to big flow multifunctional membrane formula vacuum pump.
Background technique
Diaphragm pump drives eccentric shaft by drive motor usually, and an end of connecting rod is connected on the eccentric shaft, the other end is connected with the barrier film of diaphragm pump, and the rotation of eccentric shaft is converted to the vibration of barrier film, is used for conveyance fluid or granule materials.Existing diaphragm pump mostly is monoblock pump, and connecting rod only drives a diaphragm pump job, and not only efficient is low, and balance is poor, the vibration big.In order to increase work efficiency, running has steadily proposed many bodies diaphragm pump, promptly at eccentric shaft many cover crank linkage mechanisms is installed, and every cover crank linkage mechanism drives a diaphragm pump job, and drive motor is uprightly installed, and flywheel is installed on motor output shaft.Though this many bodies diaphragm pump efficient is higher, the running is comparatively steady.But structure is comparatively complicated, not compact, the eccentric shaft discontinuity equalization, and also the number of pump is many more, rotating speed is fast more, and throw of eccentric is big more, causes pump housing shake, and noise increases, eccentric shaft easy deformation or fracture, reduce working life.Therefore, need further to be improved.
Summary of the invention
The purpose of this utility model provides a kind of big flow multifunctional membrane formula vacuum pump, its compact structure, and high working efficiency, stress equalization, running is steadily.
Big flow multifunctional membrane formula vacuum pump described in the utility model, comprise housing, drive motor, it is characterized in that: drive motor is located at an end of housing, and the output terminal of drive motor is connected with an end of bent axle, and the other end of bent axle cooperates with bearing on being located at the housing the other end; On bent axle, be provided with the connecting rod of two cover symmetries at least, two cover connecting rods respectively be located at housing two symmetry plane on a diaphragm pump be connected.The diaphragm pump symmetric arrangement can make the bent axle stress equalization, and running steadily reduces vibration.
Described big flow multifunctional membrane formula vacuum pump, it is characterized in that: diaphragm pump comprises the pump housing, the barrier film that is connected with housing, barrier film is connected with connecting rod by pressing plate, barrier film is buckled on the edge of the pump housing, be pump chamber between the two, retainer ring is buckled on the edge of barrier film, by screw on housing; Be provided with suction port and exhaust port on the pump housing, housing is stretched out on suction port and discharge road; Suction port is provided with first one-way valve, and exhaust port is provided with second one-way valve.
Optimal scheme is, housing is six cuboids that coverboard combines, and drive motor is located at an end of housing, and the output terminal of drive motor is connected with an end of bent axle, and the other end of bent axle cooperates with bearing on being located at the housing the other end; On bent axle, be provided with the connecting rod of quadruplet symmetry, the quadruplet connecting rod respectively be located at the housing face on a diaphragm pump be connected.Bent axle can be overall structure, perhaps is the segmentation composite structure; The segmentation composite structure is convenient to processing and assembling.
The utility model is compared with prior art and is had the following advantages: rotate a circle and can finish above pump sucking pump pressure process, high working efficiency twice; The diaphragm pump symmetric arrangement, stress equalization, running is steady, and vibration reduces; Simple in structure, compact, volume is little; Not only can be used as vacuum pump and use, also can be used as transfer pump and use.

Embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Referring to Fig. 1 to Fig. 6, suction port 12 and exhaust port 13 are contained on the pump housing 7 that is connected with a coverboard of housing 1, and first one-way valve 14 are installed in suction port, second one-way valve 15 is installed in exhaust port; Barrier film 8 is connected on the connecting rod 5 by pressing plate 10, and barrier film is buckled on the edge of the pump housing, forms pump chamber 9 between the two, again will, retainer ring 11 is buckled on the edge of barrier film, and is screwed and is connected on the housing.According to above method, successively three diaphragm pumps are installed on its excess-three piece coverboard.
By pipeline four barrier film pump intakes and exhaust port are connected in parallel respectively, form unified suction port and exhaust port, bent axle whenever turns around, and can finish No. four pump suctions, pump pressure process, and working efficiency significantly improves.Four diaphragm pump branches are located on four coverboards of housing, and pump housing symmetry dislocation is in twos arranged, and running is steadily vibrated very little during work.Four barrier films also can be respectively applied for different purposes.
