Graphic and text symbols for temperature relays Temperature relay is a relay that operates when the external temperature reaches a given value。The product is a contact induction sealed temperature relay，Have small size、Light weight、High temperature control precision，Extremely versatile。There are many graphic symbols and text symbols for industrial control parts. The following Xiaobian will take you to understand the graphic symbols and text symbols of temperature relays。
Blacksmith Changsha screw support base The blacksmith ball screw support seat is the bearing support seat that supports the connecting screw and the motor，Support seats are generally divided：Fixed side（postadditionKBe expressed asBK12）And support unit mounting（withFBe expressed asBF12）Theyre all preloadedJIS5Grade angular contact ball bearing。
To make the application of the motor(Speed regulating motor)Both to meet the requirements of the drag machinery，There can be long-term security、Reliable use，This is a reasonable choice of motor(Speed regulating motor)。Selective motor(Speed regulating motor)when，Reasonable selection should be made according to the technical requirements of the production machinery and the characteristics of the use environment，It is necessary to ensure safe and reliable operation，And pay attention to easy maintenance，Save on investment and operating costs。 1、Class of protection。motor(Speed regulating motor)The protection level of the enclosure，To meet the motor(Speed regulating motor)Installation position Environment requirements。 2、Rated voltage and frequency。motor(Speed regulating motor)Rated operating voltage and frequency，It should be consistent with the voltage and frequency of the power supply used。 3、Rated power。motor(Speed regulating motor)The rated power should be matched with the mechanical power of the drive as far
The non-standard hydraulic press is modified according to the lower cylinder type four-column hydraulic press，The oil cylinder of the machineUsing integral forging and precision grinding，High reliability under high pressure。The four columns of the cold-extruded hydraulic press are made of high-strength materials，Hard chrome plated surface，Good wear resistance。High track accuracy of frame and movable table，Good rigidity，Strong resistance to lateral force；Especially suitable for pressing high precision and asymmetric products；Moving table speed is fast and production efficiency is high；The cylinder is forged in one piece and finely ground，High reliability under high pressure；The four columns are made of high strength alloy steel，Hard chrome plated surface，Good wear resistance；The lower cylinder is used，Compact body。mountable、Lower return cylinder，Suitable for cold extrusion product return requirements，The upper and lower beams are joined by four pillars,And the movable beam with positioning sleeve is guided by
YBPTSeries flameproof variable frequency speed regulating three-phase asynchronous motor for inverter special motor，Be atYB2Series explosion-proof motor based，Adopt updated design，Ensure at low frequency（Low speed）Constant torque output can be maintained during operation，An independent axial fan is also used for forced ventilation，Make sure the motor is at low frequency（Low speed）Constant torque long-term operation temperature rise does not exceed its limit，True constant torque/Power output，And the speed control frequency conversion range expanded to5-60Hz（2P）、5-100Hz（4Pabove）。 YBPTSeries motor center height、power、Mounting dimension、Insulation class、Class of protection、The installation type is the sameYB2Series explosion-proof motor same，Compliant with the International Electrotechnical Commission（IEC）Standard，And can be matched with similar inverter power supply devices at home and abroad，Strong versatility，Strong interchangeability，Reliable operation，Easy maintenance。
Yaskawa motor is a relatively strict product，Experts advise non-technical personnel not to attempt disassembly，Technical personnel please carefully disassemble the operation。Lets take a look at Yaskawa motor some knowledge！ Yaskawa servo motor，Also known asYASKAWAYaskawa servo motor，Japan of origin，In Shenyang, China、There is also a factory in Jiading, Shanghai，Is to make the objects position、orientation、State and other output controlled quantity，Ability to follow the input target value（Or value）The automatic control system of arbitrary changes。It is divided into AC servo motor and DC servo motor，Semiconductors in the country、Liquid crystal manufacturing unit、Electronic component packaging device、It is widely used in machine tools and general machinery。 As a servo-driven leading enterprise，Yaskawa first proposed it“mechatronics”The concept of，Now it has become a universal term。The idea is1960Late epoch“Integrate the customers machinery with the companys motor products，To play a more powerful function
Siemens motor protectors（Also known as motor protector）The function of the motor is to give comprehensive protection，The motor starts over time、overcurrent、undercurrent、Phase break、locked-rotor、short-circuit、overvoltage、undervoltage、Electric leakage（Ground connection）、Three-phase unbalance、superheating、Bearing wear、Constant rotor eccentricity、External fault、Automatic call activation、Inverse time，A device for alarm or protection。The following Xiaobian will introduce you to the working principle of Siemens motor protector！
A brake is a brake。The brake is divided into service brake（General car for the foot brake）、Parking brake（General car for the hand brake）。bicycle、Motorcycles and other two wheels are generally full of service brakes（Instant foot brake、The handbrake is a service brake），No parking brake。
Characteristics and applications of tilt sensor
The output signal of the speed sensor can be a magnetoelectric AC signal，It can also be a Hall-type digital signal or an optoelectronic digital signal，The speed sensor is usually installed in the drive axle housing or transmission housing，The speed of the car is shown by swinging the pointer，Or generate alternating current signals，It usually consists of a magnetic core and a coil with two terminals。These two coil terminals are the output terminals of the sensor，Convert to current amplitude to represent speed。
