Chute flow Block diagram shown in Figure A second instrument. Secondary instrument is the working process: the high-precision power supply sensor, the sensor output signal to the instrument by the compensation circuit, through the compensation circuit can blast out of date material in the absence of instrumentation, sensor output is zero. Measuring amplifier to the input signal is amplified to give the small / F converter circuit and alarm circuit. / F converter circuit converts the DC signal is sent to the instantaneous frequency signal and the accumulated totalizer display circuit, respectively, the instantaneous flow of materials and accumulated totalizer display. Instrument before use, flow through the upper and lower preset value of the work,Moncler cheap, the alarm circuit will be able to work more when the alarm limit. The more limited signals reflected by the acousto-optic devices. Coefficient circuit is used to preset the material coefficient, the coefficient from the measured physical properties of materials are determined for each material in the measurement must be repeated before the dynamic calibration are to find out the coefficient and then value as of the kind of five coefficient of the material measured in the coefficient of control wells in the preset. Fourth, the characteristics of flow meter chute chute flow meter with the experimental data with closed structure, materials spills and dust will not pollute the environment. Flow volume is small, easy to install. Load cells installed in the sealed box, good stability. Materials for high temperature measurements up to S00 ℃ wide measuring range,ugg Boots Billig, from several tons per hour, thousands of tons per hour. The flowmeter flow meter compared with the impact, with a simple structure, stable, no oscillation and so on. Inadequate measurement accuracy is influenced by the nature of the material, but when used in the field can be corrected by physical calibration. LLJ now we developed a type of chute 10 Mu meter installation in Table 1 is the static weight calibration process records the value of weight difference between the theoretical value puppets relative error (kg) (mA) (mA) (mA) 0O0l2. 6312.6ll0.0200.7725.1865.229 ~-0.036-0.6937.7717.833-0.062-0.794l0.446-7 of a series of calibration objects in Table 2 records the amount of guests dancing bovine testis measured words The average number of words in real time to jump five five indicates the deviation indicates the precision feeding amount (kg) (sec) (j) (kg / words) (kg,ugg boots cheap, word) (kg, word) (kg) (kg) 5053O5010.1499 .650-5.35-1.0592315101 Z5239.832-3168-1.304263, 15279.749.9939.993269.811 +6.8】 l2.52601526l02g. 8l8 a 0.182-0.07290l52910289.797-0203-0. G7 Danjiang cement production line to extract the actual calibration test data shown in Table 1, Table 2. Chute flow metering device as powder material,MBT shoes cheap, according to its characteristics, such as computer equipped with automatic instrument or system can automate the process of production, but also to facilitate the Enterprise economic accounting, the application will be more and more widely. Circular distribution of holes of location error evaluation criteria and principles of graphic Tsai Tun and (College of) the distribution of the feed hole circumference degree in graphic principle of location different from the distribution of non-circular hole of location degrees. This paper set out the mathematical principles illustrated on the theoretical basis and practical methods, that diagrams should pay attention to basic problems. One hole of location error prince Yu characteristics of the graphical method based on error tolerance of each hole together with the re-sets the error circle. Circumference of the hole distribution diagrams of location error is no exception, but has its own characteristics. Figure 1a shows the distribution of circular hole components, the ideal location and prepared hole tolerance zone shown in Figure 1b. 2,3,4 If the tolerance zone around the hole center of rotation angle of rotation corresponding theory (il ~ gD., 180., 270.), The ideal location and tolerance to 8 will coincide with a map l. For a change: If the tolerance of each hole with the corresponding theoretical shift distance (for example hole left Mu 2, 40mm, and then move 4Omm), the ideal location and tolerance zone overlap, but also before and after the tolerance zone of two transformations very different angular positions, so there is a fundamental transformation of two different. Hereinafter referred to as the previous polar coordinate transform method, the latter for the rectangular coordinate transformation method. =, Evaluation criteria Holes and the localization of the geometric frame are summarized as follows: geometric frame be fixed; geometry geometric box frame can be rotated to shift j; geometric frame can shift fork can be rotated (complex movement). According to the localization frame geometry, the author made the following evaluation criteria for an error circle. If the box is fixed and geometry, the use of polar diagrams. Inclusion in the center of the smallest painting on the origin of coordinates, the circumference of at least one point (the actual hole center) contacts. This said radius method (Figure 2). 相关的主题文章： ugg boots günstig Measuring instruments to determine and model calibration interval _286 Moncler cheap Stoichiometric content _2625 ugg boots cheap Three-dimensional LDV optical system technol |
