introduction: Usually the flat forging machine has some working characteristics of the hot die forging press,That is, the static pressure at work,And it is borne by the frame itself;The slider must travel;Have good guide device, etc。 The reason why such devices can be applied and developed,Is because it also has the following working characteristics: 1)There are two parting surfaces; 2)The main slider is moving horizontally; 3)Positioning device with blank。 Due to the above working characteristics of the flat forging machine,Its die forging process and die design will have the following characteristics: 1)can

introduction: one、Structure and working principle of reciprocating pump Main component:Pump cylinder、piston,Piston rod and suction valve、Discharge valve。 Working principle:As the piston moves from left to right,Negative pressure is formed in the pump cylinder,The liquid in the storage tank enters the pump cylinder through the suction valve。When the piston moves from right to left,The liquid in the cylinder is squeezed,Pressure build-up,Discharge by discharge valve。 Reciprocating piston,Each inhales and expels liquid once,Called a work cycle;This type of pump is called a single acting pump。 If the piston goes back and forth once,Inhale and expel fluids twice,

introduction: one、When installing the reducer,Special attention should be paid to the alignment of the transmission center axis,The alignment error can not be higher than the compensation amount of the coupling used in the reducer。After centering the reducer as required,It can obtain more ideal transmission effect and longer service life。 two、There are many types of couplings used in the reducer,However, it is best not to use the rigid fixed coupling,Mainly because the installation of this type of coupling is more difficult,If the installation is not good, it will increase the load,Easy bearing[bearing:bearing(“Bearing”,Japanese person

introduction: Impact 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。]What are the main factors of vibration? Stiffness determined by bearing structure design parameters,compliance,Quality,The vibration system composed of damping and so on will produce vibration which is suitable to its mechanics under running conditions。 Vibration caused by deviations in manufacturing processes,The smaller the deviation
