The meaning of thermostat is literally understood to be a machine that regulates the temperature。The temperature protection device transmits temperature to the temperature controller，Then the temperature controller calculates whether the temperature is suitable and issues the switch command，To control the operation of the equipment，Achieve the ideal temperature and energy saving effect。 one、Working principle The working principle of the temperature controller first requires automatic real-time acquisition and monitoring of the specific data of the surrounding environment through the temperature sensor。When the ambient temperature exceeds the preset value for the temperature controller，You can set up automatic control temperature return difference。If the temperature continues to rise，When raised to temperature controller
Buffers are widely used in our daily life and production activities，Because of the variety of buffers，The advantages and disadvantages of each type are different，So there are some difficulties in choosing a buffer。The following describes the advantages and disadvantages of oil buffer versus other buffers。 one、Oil pressure buffer Oil buffer is a kind of mature buffer device，It is an upgrade of other types of buffers。The comprehensive performance of the oil buffer is strong，Its not just earthquake-resistant，Noise abatement，And no rebound at work，Long life。Therefore, most people choose oil pressure buffer when choosing a buffer
In the minds of many，The power adapter is the charger。But is this really the case？Of course not。There is a huge difference between a power adapter and a charger，Below we will see how the power adapter works、The damage phenomenon and how to distinguish between the power adapter and the charger are analyzed from multiple perspectives。 one、Is the power adapter a charger First of all, you need to say yes：A power adapter is not the same as a charger in most cases。 In terms of what needs to be accomplished，Power adapters focus on electrical appliances、Industrial equipment etc provided
one、Classification of high frequency switching power supplies The first thing we need to be clear about，According to different classification criteria，The classification of switching power supplies is also varied。 1.According to the switching power supply input/Output types can be classified intoDC/DCType switching power supply andAC/DCType switching power supply，The main difference is that there is a big difference in the converter inside。 2.According to the type of control circuit of switching power supply, it can be classified into resonant switching power supply and non-resonant switching power supply。 3.According to the switching power supply control mode and use of different can be divided into
Performance application and characteristics of linear guide。With the continuous development of modern manufacturing technology，The traditional manufacturing industry has undergone great changes，Numerical control technology、Mechatronics and industrial robots have been more widely used in production。At the same time, the positioning accuracy of the mechanical transmission mechanism、Guiding accuracy and feed speed are constantly improving，The traditional guiding mechanism has undergone great changes。 Since the1973Since the beginning of commercialization，The rolling linear guide pair has its unique characteristics，Gradually replaced the traditional sliding linear guide，It has been widely used in industrial production。Adapted to todays machinery for high precision、High speed
Linear guide rail is the main source of oscillation which is difficult to control，Because the oscillating screen relies on a large incentive force to maintain the speed and friction coefficient of the linear guide rail，Therefore, the radial force on the linear guide rail is very large。Oscillating screen during operation，Large exciting force will cause elastic oscillation of linear guide system。If not smooth，It will produce large friction and make the temperature rise of the linear guide rail too high，Excessive thermal expansion，The radial clearance is obviously reduced，This in turn increases friction，Further progress has been made in temperature rise。An oscillation system composed of linear guide rail and bias system，It can be regarded as a system of single degrees of freedom。There is a system of drive shaft and driven shaft of linear guide
Idler refers to a gear that plays a transmission role between two transmission gears that do not contact each other，Engage both gears at the same time，Used to change the direction of rotation of the passive gear，Make it the same as the driving gear。It just changes the steering, it doesnt change the gear ratio，Call it idler。 An idler is a wheel that does no work，It has a certain energy storage function，It helps the system stability。Idler is widely used in machinery，It helps connect distant axes。It just changes the steering and doesnt change the gear train ratio。 In the wheel train，If a gear is the driving wheel of the previous drive，Its the last stage of transmission
Aligning roller bearings have double rows of rollers，Have an outer ring1One common spherical raceway，With an inner ring2raceway And inclined to an Angle relative to the bearing axis。This ingenious construction enables it to have automatic aligning performance，Therefore, it is not easy to be affected by the Angle of shaft and bearing box seat on the error or shaft bending，Suitable for mounting errors or shafts Deflection caused by Angle error。 The bearing can bear radial load in addition，It can withstand both directions Use the axial load。Aligning roller bearings have two kinds of inner holes: cylindrical and conical，The taper of the conical taper hole is1：30 and1：12Two kinds of，The conical bore bearing is fitted tightly
For the reducer matching motor selection，Many friends said：This seemingly simple question，But in fact, there are many related terms，Its a complicated question。There really arent many people who can actually get it right and apply it correctly。Most reducer due to speed ratio，There is an upper limit for motor power depending on the model。The basic speed ratio of the same type is larger，The smaller the motor。Determine the torque and speed required by the matching motor type of the reducer，Electric machine。Or determine the need to use the power sleeve motor to push the reducer。Today, Xiaobian mainly tells about the choice of motor matching reducer： The following is the traditional calculation method for selecting the matching motor of the reducer，I believe many friends are pressed
diagnosis： 1.The fire break test was carried out on a cylinder，The noise diminishes or disappears，For the cylinder bearing ring。 2.The sound is clear when the engine speed changes from idle to medium speed，With increasing speed，Accentuate the sound，Bearing noise。 3.It sounds at all speeds and temperatures，And the engine vibrates，The fire break test doesnt change the sound，The bearing alloy is ablated。 Elimination method of bearing failure： 1）Fatigue pitting When the rolling bearing is loaded.In the rolling body with inside、The contact surface of the outer ring will produce contact stress.by
