Abstract
The utility model relates to an oil-free lubrication electric diaphragm pump, comprising a base, an electric motor, a speed reducer, a transmission mechanism, a diaphragm, a cylinder block, etc. An oil-free lubrication lining is adopted in the transmission mechanism to make the rotation, the swing motion, and the sliding position in a crank connecting rod mechanism free of motor oil filling during the working process, an oil-free lubrication structure is formed, and the cylinder block forms an oil-free hollow cavity. As a result, the utility model solves the difficult problem that when the diaphragm breaks, the medium depositions of lubricating oil pollute conveyed materials.
Description
Electric diaphragm pump is a kind of of self-priming pump class.
At present, electric diaphragm pump all has oil lubrication.As: the product that Yongjia, Zhejiang thermal power unit factory goes out all is like this.In work, all want filling device oil lubrication moving link.Oil is flowing liquid, of long duration, oil how, can be penetrated into the diaphragm pump cylinder body along motive position among, the diaphragm of diaphragm pump belongs to soft easily damaged parts, and the oily medium of deposition mixes with the liquid material that diaphragm pump is carried in the cylinder body in case the diaphragm damage will occur.In this case, throw away mixed material and can cause raw-material waste and befouling environment, do not throw away and continue to carry this mixed material, can reduce quality of product again.If what diaphragm pump was carried is the flammable and combustible liquids material, also need hundred times of Fire Hazard Areas.
The purpose of this utility model just provides a kind of electric diaphragm pump that need not oil lubrication.
Principle of the present utility model is such: in every pair of fastness in diaphragm pump, add a lining, this lining is that self lubricating material is made.As: the oil-containing or steel backing one plastic composite etc. of oil-containing material not.When every pair of fastness motion, this lining plays lubrication.As: lining of being made by steel backing one plastic composite or poly-tetrafluoro oil-free lubrication lining are contained on the pedestal that is connected with the diaphragm pump cylinder body, and sliding axle constitutes a pair of fastness in cylinder body.When sliding axle be fixed on lining on the pedestal when doing relative movement, plastic medium on the sleeve surface will shift on sliding axle, form stable plastic solidification lubricating film on sliding axle, constituted the selflubricating between lining and sliding axle, form no oily cavity in the cylinder body this moment.
The utility model has also adopted driving torque big, the cycloid pin tooth planetary speed reducer that step of reduction is many, and cylinder body is fixed on the pedestal forms the diaphragm pump cylinder body with pedestal.
Describe in detail below in conjunction with accompanying drawing
Fig. 1 is a single cylinder oil-free lubrication electric diaphragm pump.(1) be motor, (2) are cycloid pin tooth planetary speed reducer, and (3) are transmission shaft, (4) be crank, (5) be the connecting rod crank lining, (6) are connecting rod, and (7) are connecting rob bushing, (8) be shaft coupling, (9) be lining, (10) are cylinder body, and (11) are transmission shaft, (12) be diaphragm, (13) are pedestal.
Fig. 2 is a twin-tub oil-free lubrication electric diaphragm pump.(14) be pedestal, (15), (16) are one-way valve, and (17), (18) are pipeline, and (19), (20) are interface tube, and (1) to (12) is all consistent with Fig. 1, wherein (1), (3), (5), (7) since view limit not give and mark.
Among Fig. 1, motor (1) drives cycloid pin tooth planetary speed reducer (2), drives crank (4) by transmission shaft (3) and rotates, crank (4) drivening rod (6) swing, drive sliding axle (11) by shaft coupling (8) and move up and down, to drive diaphragm (12) to-and-fro motion.Cylinder body (10) is fixed on the pedestal (13), and sliding axle (11) is to form a pair of fastness with the lining (9) that is contained on the pedestal (13).Because the motion of diaphragm (12) forces the one-way valve of cylinder body both sides to replace opening and closing, liquid is constantly sucked and discharge.One connecting rod crank lining (5) is housed between connecting rod (6) and crank (4), is fixed on the connecting rod (6).In connecting rod (6) and shaft coupling (8) cooperation place, a connecting rob bushing (7) is arranged, be fixed on the connecting rod (6).Between sliding axle (11) and pedestal (13), a lining (9) is arranged, be fixed on the pedestal (13).Above-mentioned said three kinds of linings are made by steel backing one plastic composite or poly-tetrafluoro oil-free lubrication material or oil-containing material.
The utility model also can be applicable to the diaphragm pump of multi-cylinder.As shown in Figure 2, motor (1) drives cycloid pin tooth planetary speed reducer (2) and drives crank (4) rotation by transmission shaft (3), crank (4) drives two or more connecting rods (6) swing, driving sliding axle (11) by shaft coupling (8) moves, to drive diaphragm (12) to-and-fro motion respectively, cylinder body (10) is fixed on the pedestal (14) too, and sliding axle (11) forms a fastness with the lining (9) that is contained on the pedestal (14), because the motion of diaphragm (12), the one-way valve (15) that forces cylinder body (10) both sides to link to each other, (16) alternately opening and closing make liquid in pipeline (17), (18) constantly suck in and discharge.
Owing to adopted cycloid pin tooth planetary speed reducer, and cylinder body is fixed on the pedestal lining of employing oil-free lubrication between each fastness, therefore the utility model volume is little, and driving torque is big, and step of reduction is many, make easyly, can send particle thick liquid, mud, paper pulp.Especially the inefficient liquid of shallow liquid level centrifugal pump class is arranged, inhaled, particularly the utility model adopts oil-free lubrication, the material that diaphragm pump is carried has been avoided the situation of mixing with lubricant oil, thereby enlarged electric diaphragm pump in aspect using scope such as pharmacy, diet, the worker's raw materials of refining, for electric diaphragm pump has increased new varieties.
