An electrolytic machining method for removing burrs from metal parts by electrolysis﹐English abbreviationECD。 figure Electrolytic deburring principle The picture shows the principle of electrolytic deburring。Tool cathode(General brass)It is fixed near the burring part of the workpiece﹐Theres a certain gap between the two(Generally speaking0.3～1millimeter)。The conductive part of the tool cathode is aligned with the bristle edge﹐Other surfaces are covered with an insulating layer﹐The electrolytic action is concentrated in the burr part。During processing, the tool cathode is connected to the negative electrode of the DC power supply﹐The workpiece is connected to the positive terminal of the DC power supply。The pressure is... 0.1～0.3Mpa of low pressure electrolyte
For bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]sealability，influenceKOYOThere are two main factors for bearing sealing performance，Manufacturing accuracy，The fit and assembly quality between the parts。To solve this problem, we must make progress in these two aspects
There are many types and models of construction machinery and equipment，The main types are：forklift、Shovel and transport machinery、Compacting machinery、Concrete machinery。 Many modern large construction machinery such as asphalt mixing equipment、Stabilized soil mixing equipment、 The scale of the combined crusher is very large，Each part has a mass of tens to hundreds of tons，And construction machinery is mostly in sand、gravel、Work in harsh environments such as rain and snow，Its technical condition is bound to decline faster than other machinery，The fit between the parts will appear to different degrees of loosening、wear、Corrosion and scale formation，Each connection
If two incompatible oils mix，Never mix incompatible oils and fats。Usually the consistency is soft，Finally, it is easy to lose grease and cause damage，If you dont know your car bearings[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]What kind of grease was used，The original grease must be removed first，Then an oil is added
[Main use] This machine is suitable for medicine、Chemical engineering、pesticide、Food and grain industries，Extremely versatile。 [Working principle] The machine uses the high-speed relative motion of the movable and fixed gear discs，Impact the crushed material through the teeth、The combined action of friction and impact between materials is obtained。Simple native structure、solid、Smooth running、Good crushing efficiency，The crushed material can be discharged directly from the grinding chamber of the main machine，The particle size is obtained by replacing the mesh screen with a different diameter。 [Technical data]

How to solve the problem of electric forklift The main reasons for the partial failure of electrical apparatus are:The battery forklift suddenly stopped moving forward and backwardThere was no response to the promotion,The forklift is going in a rush,The forward speed cannot be adjusted, etc。However, the electric forklift took a long time，How should we carry out the maintenance of electric forklift trucks？ 1、The lifting speed is too slow or can not lift the main reasons，Tank shortage，The oil filter is blocked，The hydraulic oil temperature is too high,The hydraulic oil is too thin，Hydraulic line leakage，The pressure of the multiway valve is improperly adjusted.Brake failure agent
QBYSeries pneumatic diaphragm pump is a new type of conveying machinery，It is the most novel type of pump in China。Compressed air is used as the power source，For all kinds of corrosive liquids，Liquid with particles，High viscosity、volatile、inflammable、A highly toxic liquid，Theyre all pumped out。Its performance parameters are consistent with those of the Federal Republic of GermanyWILDENPUMPS、ColumbianMARIOWPUMPSclose。 At present, series production has been formed，There are eight diameters：φ10mm（3/8“）、15mm、25mm、40mm、50mm、65mm、80mm、100mm。Four kinds of wood
The main feature of worm gear reducer is that it has reverse self-locking function，Can have a large deceleration ratio， Reduction gear（figure2） The input and output axes are not on the same axis，Its not on the same plane。But it is generally larger，Transmission efficiency is not high，Low precision。The harmonic transmission of the harmonic reducer uses the controllable elastic deformation of flexible components to transmit motion and power，Small volume、High precision，But the disadvantage is that the flexible wheel life is limited、Shock intolerance，The rigidity is poor compared with metal parts。The input speed cannot be too high。The advantage of the planetary reducer is that the structure is relatively compact，Small return clearance、High precision
Compare high speed and rate single stage transmission，Will be able to achieve reductions87than1 ，exceed90 ％Efficiency of，If we transmit through multiple layers，Greater compression ratio。 〇Compact structure，Due to the small principle，Planetary drive，Input axis Output axis in the same row，So its size is as small as possible for the model。 〇Smooth and low noise operation cycloidal gear meshing more overlap coefficient and mechanical mechanism balance，Thus vibration and noise are limited to a minimum。 〇Reliable use，Long life due to the main components of carbon chromium steel material used quenching treatment（ HRC58 62High strength，Sum local flooding
