Abstract
The utility model discloses a two effect diaphragm pump bent axles of double -cylinder, end boss behind crank, bent axle free end, rod journal, balancing piece, trunnion and bent axle, rod journal and balanced block interleaving are installed between bent axle free end and trunnion, balancing piece upper portion sets up rotatory passageway, and rotatory passageway inner wall is equipped with the axle journal through -hole, pack annular external coating between rotatory passageway and the axle journal through -hole, the lower part installation temperature -sensing ware of balancing piece, the surperficial inlayer of trunnion and rod journal sets up speed sensor. This bent axle, it is structurally progressively perfect, through temperature -sensing ware monitoring pivot surface, prevent to utilize annular external coating because the high temperature causes surface crack, give the cooling of pivot surface, unset according to the effect demand utilizes the speed sensor monitoring, more portably controls, has not only prevented the waste of resource, and the effect accords with manufacturing person's expectancy more moreover.
Description
Technical field
This utility model relates to membrane pump part technical field, is specially a kind of double cylinder double acting membrane pump bent axle.
Background technology
Membrane pump, also known as controlling pump, is carried out the main Types of device, by accepting the control signal of modulating unit output, goes to change fluid flow by power operation.Membrane pump is typically made up of actuator and valve.Employing compressed air is power source, for various corrosive liquids, the liquid of band granule, high viscosity, volatile, inflammable, hypertoxic liquid, all can be taken out light and exhaust.Bent axle, is the main rotary gadget of engine, and after loading onto connecting rod, upper and lower (back and forth) motion that can accept connecting rod becomes circulation (rotation) motion.Mainly including trunnion, connecting rod neck, trunnion is installed on cylinder body, and connecting rod neck is connected with crank pin end pore, and connecting rod small end hole is connected with steam-cylinder piston, is a typical slider-crank mechanism.Current membrane pump bent axle, especially the bent axle of double cylinder double acting membrane pump, the most perfect, and operate excessive altofrequency, and rotating shaft surface temperature is too high, face crack easily occurs；And not fixing along with effect demand, speed of crankshaft exists, it is difficult to monitoring, to such an extent as to bad control, not only waste resource, and also not fully up to expectations in effect.
Utility model content
The purpose of this utility model is to provide a kind of double cylinder double acting membrane pump bent axle, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of double cylinder double acting membrane pump bent axle, including crank, crankshaft free-end, rod journal, balance weight, trunnion and crankshaft rear end flange, described crank and crankshaft rear end flange are separately positioned on the two ends of bent axle, described crankshaft free-end connecting crank, described rod journal and balance weight intersection are arranged between crankshaft free-end and trunnion, described balance weight top arranges rotating channel, and rotating channel inwall is provided with axle journal through hole, annular external coating is filled between described rotating channel and axle journal through hole, temperature inductor is installed in the bottom of described balance weight, the surface internal layer of described trunnion and rod journal arranges speed probe.
Preferably, rod journal and the balance weight crossed-symmetrical of described trunnion both sides is arranged.
Preferably, described balance weight be shaped as rectangle or trapezoidal.
Preferably, described temperature inductor and speed probe are all connected to computer by communicator.
Compared with prior art, the beneficial effects of the utility model are: this bent axle, structurally gradual perfection, monitor rotating shaft surface by temperature inductor, prevent from, because temperature is too high, causing face crack, utilize annular external coating, to rotating shaft surface cooling；According to not fixing of effect demand, speed probe is utilized to monitor, easier control, not only prevent the waste of resource, and effect more conforms to the expection of maker.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is balance block structure schematic diagram of the present utility model；
Fig. 3 is rod journal structural representation of the present utility model.
In figure: 1 crank, 2 crankshaft free-ends, 3 rod journals, 4 balance weights, 5 trunnions, 6 crankshaft rear end flanges, 7 rotating channels, 8 axle journal through holes, 9 annular external coating, 10 temperature inductors, 11 speed probes.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1-3，A kind of technical scheme of this utility model offer: a kind of double cylinder double acting membrane pump bent axle，Including crank 1、Crankshaft free-end 2、Rod journal 3、Balance weight 4、Trunnion 5 and crankshaft rear end flange 6，Described crank 1 and crankshaft rear end flange 6 are separately positioned on the two ends of bent axle，Described crankshaft free-end 2 connecting crank 1，Described rod journal 3 and balance weight 4 intersection are arranged between crankshaft free-end 2 and trunnion 5，The rod journal 3 of described trunnion 5 both sides and balance weight 4 crossed-symmetrical are arranged，Described balance weight 4 be shaped as rectangle or trapezoidal，Described balance weight 4 top arranges rotating channel 7，And rotating channel 7 inwall is provided with axle journal through hole 8，Annular external coating 9 is filled between described rotating channel 7 and axle journal through hole 8，Temperature inductor 10 is installed in the bottom of described balance weight 4，The surface internal layer of described trunnion 5 and rod journal 3 arranges speed probe 11，Described temperature inductor 10 and speed probe 11 are all connected to computer by communicator.
Operation principle: this bent axle is when the thrust carrying out being transmitted by piston rod becomes the torsion rotated, crank 1, crankshaft free-end 2 and crankshaft rear end flange 6 rotate integrally, simultaneously rod journal 3 and balance weight 4 do expansion spinning turn, drive trunnion 5 simultaneously, the temperature of journal surface is monitored in temperature inductor 10 moment of journal surface, in case crackle occurs, annular external coating 9 between recycling rotating channel 7 and axle journal through hole 8 is lowered the temperature, the size of rotating speed monitored by speed probe 11 in journal surface, controls the effect that bent axle produces.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
