Hardware knowledge: the use and types of gauges
Measuring plate use A flat plate is a planar reference device for workpiece inspection or scribing. The shape is as shown. This definition indicates the nature, function and use of the plate. A flat plate is a device that reproduces a quantity in a fixed form, which is a physical measuring tool. The flat working surface is often used as a plane reference for collating and adjusting other measuring instruments or as a standard to be compared with the measured part. It is used for shape error and measurement, so it is a shape error measuring instrument. The naming of the plate also points out the specific use - for workpiece inspection or scribing. Larger sizes of splints, when mounted on a dedicated stand, are collectively referred to as platforms. Measuring plate type According to its material, it is divided into steel flat plate, cast iron plate and rock plate, marble plate and granite plate. According to its structure, the cast iron plate is divided into ribbed plate and box type. The rock plate is divided into flange type and flangeless type. According to its use, it is divided into inspection plate, scribing plate and sand pressing plate according to its accuracy level. , 0, 1, 2, 3 grade plates, of which 2 or more are inspection plates, and 3 are line plates. This division further ensures the process performance and intrinsic quality of the high precision flat panel. A culture plate is the most commonly used form of solid medium used to obtain pure culture of microorganisms. It is a medium solid plane formed by cooling solidified solid medium in a sterile culture dish, often referred to simply as a plate ( Plate).

The hydraulic system of medium and small hydraulic Excavator Spare Parts has a clear trend of changing to a variable system. Because the variable system compensates by increasing the flow rate when the pressure is reduced during the operation of the oil pump, the hydraulic pump power is kept constant, that is, the Excavator spare parts equipped with the variable pump can often fully utilize the maximum power of the oil pump. When the external resistance increases, the flow rate is reduced (the speed is reduced), and the digging force is multiplied; a three-circuit hydraulic system is used. Generate three independent work movements that do not affect each other. Achieve power matching with the slewing mechanism. The third pump is switched on in other working motions and becomes the second independent fast motion of the open circuit. In addition, hydraulic technology is commonly used on excavators, creating conditions for the application and promotion of excavators for electronic technology and automatic control technology.
