introduction：A load cell is actually a device that converts a mass signal into a measurable electrical output。The use of sensors should first consider the actual working environment in which the sensor is located，This is the correct choice of load cellvital，It is related to whether the sensor can work properly and its safety and service life，And even the reliability and safety of the whole weighing apparatus。The basic concept and evaluation method of main technical index of load cell are discussed，There are qualitative differences between the old and the new countries。There are mainlyStype、Cantilever type、Spoke type、Plate-ring type、bellows、Bridge type、Cylinder-type and other styles。 What are the classifications of load cell： The load cell is divided into photoelectric type according to the conversion method、Hydraulic type、Electromagnetic type、capacitive、The magnetic pole changes form、Vibrating type、Gyro ceremony、Resistance strain formula, etc8class，The resistance strain gauge is the most widely used。

introduction：The cavitation phenomenon of the pump is determined by the pump itself and its suction device。The pump is in operation，If it flows over a local area of the component（Usually somewhere behind the entrance of the blade）For some reason，When the absolute pressure of the pumped liquid is reduced to the vaporization pressure of the liquid at the current temperature，This is where the liquid begins to vaporize，Produce a lot of steam，blister，When the liquid containing a large number of bubbles passes forward through the high-pressure area in the impeller，The high-pressure liquid surrounding the bubble causes the bubble to condense and burst。As the bubbles condense and burst，Liquid particles fill holes at a high rate，There is a very strong water impact in this instant，And hit the metal surface with a high impact frequency，The impact stress can be hundreds to thousands of atmospheres，The impact frequency can reach tens of thousands of times per second，In severe cases, the wall thickness will be broken down。The process o

introduction：Rolling guide Rolling guide rail is a kind of linear guide rail。There are generally two kinds of linear guides，One is rolling，One is sliding，A rolling straight slide is a rolling guide，It consists of a steel ball in an infinite rolling cycle between the slide block and the slide rail，The load platform can easily move in a linear manner along the slide rail with high precision，Its coefficient of friction can be reduced to that of conventional slide-guided1/50，Make it easily accessibleμmLevel of positioning accuracy。 advantage： 1、High sensitivity，There is little difference between the dynamic friction coefficient and the static friction coefficient，Thus stationary，Crawling is not easy when moving at low speeds。 2、High positioning accuracy，Repeatable positioning accuracy0.2μm。 3、Low friction resistance，portable，Low wear、Good accuracy retention。

introduction：fagDouble row deep groove ball bearings The design of double row deep groove ball bearings is basically the same as that of single row deep groove ball bearings。The raceway with the shaft shape of the deep groove ball and the excellent fit between the raceway and the steel ball。Double row deep groove ball bearings bear radial loads in addition，It can also withstand axial loads acting in both directions。 Bearing characteristic Deep groove ball bearing is the most representative rolling bearing，versatile。Suitable for high speed or even very high speed operation，And very durable.，No frequent maintenance required。The friction coefficient of this kind of bearing is small，Limit speed height， Simple structure，Low manufacturing cost，Easy to achieve high manufacturing accuracy。 Varied in size range and form，Application in precision instrumentation、Low noise motor、CARS、Motorcycle and general machinery industries，It is the most widely used type of bearing in the machinery industry。Mainly bear radial load，It can als

introduction：fagDeep groove ball bearing model FAGDeep groove ball bearing is technologyFAGMain shaft bearing：The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。They are not removable。These bearings can be open，There are also sealed ones。Main shaft bearings have limited tolerances。They are particularly suitable for bearing arrangements that require very high guiding accuracy and speed capability。They are particularly suitable for the bearing arrangement of the shaft of the machine tool。 FAGDeep groove ball bearing is with solid outer ring、Universal use of inner ring and ball and cage assembly、Self-retaining bearing。These products are simple in design，Long service life and easy maintenance；Can be divided into single and double column design and opening and sealing design。Due to the production technology used，The open bearing can still be transferred into the hollow on the outer ring for sealing
