5 results about "Incorrect Measurement" patented technology

This invention belongs to the field of bipolar plate testing technology, specifically an automatic perforation testing device for hydrogen production bipolar plates. It includes a support base with an adjustable height frame on top; a load-bearing device on top of the adjustable height frame for holding the bipolar plate; and a rotating component located at the axis on the upper surface of the load-bearing device for twisting the bipolar plate. The load-bearing device includes a metal frame with fixing rods evenly inserted into its inner wall. This device can replace manual testing. Through a scanning component at fixed points, it twists the clamped and rotating bipolar plate, thereby detecting the flatness of the perforations on the outer surface of the bipolar plate. To ensure accuracy, the rotation speed and number of rotations of the bipolar plate can be controlled, ensuring the scanning component can perform a comprehensive inspection of the bipolar plate and avoiding missed or incorrect measurements.

The utility model relates to a special tool for measuring the abrasion loss of a thermocouple of an internal mixer, and belongs to the field of testing tools for mixing tire rubber. The measuring scale is of a cylindrical structure, data scales are machined on the outer cylinder wall of the measuring scale, a screw hole is machined in the cylinder wall of the measuring scale, a locking bolt is screwed in the screw hole in a threaded fit mode, a compression spring is installed in an inner cavity of the measuring scale in the axial direction, and the outer end of the compression spring is connected with a cone. The device has the beneficial effects that data deviation caused by incorrect measurement in the measurement process is avoided, and the data for measuring the abrasion loss of the wear-resistant head of the thermocouple is accurate.

The utility model relates to the technical field of inner ball cage detection, and discloses an inner ball cage riveting detection tool, which comprises a measuring block part and a hand-held block part, the opposite end surfaces of the measuring block part and the hand-held block part are contacted, the hand-held block part is fixedly arranged at the top end of the measuring block part through a hexagon socket screw, the measuring block part is provided with a scale line slot, and the scale line slot is fixedly arranged on the hand-held block part. The scale line grooves are distributed on the front side face and the rear side face of the measuring block part, and the width of the cross section of the measuring block part is gradually reduced from top to bottom. A traditional caliper measuring mode is replaced, the accurate effect of the measuring position can be guaranteed, the problem that the hand shakes in the measuring process is avoided, the measuring stability is improved, and the measuring efficiency is improved. And the reduction of the qualified rate of products caused by incorrect measurement size is prevented.

The utility model discloses an antithrombotic gradient pressure tape code number measuring scale which comprises a measuring scale body. Scale lines and scale vector values corresponding to the scale lines are arranged on the two sides of the measuring ruler body in the length direction; a code number marking area and a measuring method and part marking area are arranged in the middle area of the measuring ruler body in the length direction. And the code number marking area comprises code number corresponding areas corresponding to the measurement parts. According to the measuring tape, a measuring method and a measuring part marking area are arranged on the measuring tape, operation of nursing staff can be better facilitated, the corresponding code numbers of different body types and different parts are marked in the middle of the measuring tape through areas of different colors, the corresponding code numbers can be obtained through direct measurement, and the measurement and comparison time is shortened; the influence on the use effect of a patient and the prevention efficiency of venous thrombosis caused by inconsistent code number due to incorrect measurement parts and measurement methods can be avoided; the device is easy to operate and high in practicability, convenience is provided for nursing work, and the working efficiency is greatly improved.

According to the integrated oil feeding tool pipe for the ship and the using method, after the integrated oil feeding tool pipe is installed at a time, in the whole oil feeding period, a temporary pipeline does not need to be adjusted, switching between oil feeding outside a machine and oil feeding inside the machine can be achieved through control over a butterfly valve, the pipeline adjusting time can be shortened by 3-4 days, and the oil feeding efficiency is improved. And the risk that the pipeline and the flushing oil are polluted again in the pipeline adjusting process is prevented. Meanwhile, on-line granularity measuring equipment is additionally arranged, lubricating oil particles can be measured in real time, the trend change of the granularity and data printing are observed through the measuring equipment, the time for taking an oil sample and then testing a report in the past is shortened, incorrect measurement caused by pollution of the oil sample is also prevented, and the measuring accuracy is improved. Meanwhile, the oil throwing data of the main engine of each ship can be stored through the application of an online granularity measurement and storage function, later data query and summarization are facilitated, the total construction time of oil throwing of the main engine is shortened through the application of pipeline integration and measurement equipment, and meanwhile the ship building speed is increased.
