Changzhi Hydraulic Parts Factory successfully developed a new type of internal gear type variable speed power assist pump

Changzhi Hydraulic Parts Factory in Shanxi Province has recently developed a new type of internal meshing variable-speed power-assisting pump. Its technical indicators have met the design requirements, filling a blank in China and replacing imported products.
The pump is a power source for a shifting hydraulic system of a motor vehicle, and has a compact structure, low noise, and long help. The gearbox adopts a semi-automatic or fully-automatic hydraulic transmission control system, which frees the driver from manual operation, reduces labor intensity, and improves driving comfort, reliability and safety of the vehicle. Especially when working in reverse, the automatic shifting improves the working efficiency and service life of the gearbox, which can meet the matching needs of automobiles, loaders and excavators.

High-temperature 2-color Ratio Pyrometer

This classification includes two color infrared pyrometers measuring range start from 600℃. Two-color pyrometer determines the temperature of an object by measuring the ratio of energy at two different wavelengths. The advanced software and hardware design help pyrometers meet the application in harsh environment as moisture, dust, target size change, partial blockage and emissivity change, even if the detection signal attenuates 95%, the temperature measurement results will not be effected.

In two color mode, pyrometer measure the highest temperature in an area without being limited by the size of the measured target. The two-color mode determines the temperature by the ratio of the signal from two wavelength. When with small measuring object, dusty, water vapor and foggy, changing distance, partially occlusion, and frequently changing emissivity, the signals of two wavelength fall simultaneously and the ratio remains the constant after division.

Pyrometer detectors are normally laminated silicon, products are usually applied to metallurgical industry(rod and wire mills, Hot rolling mills), foundry, cement kiln, induction heating, heat treatment, heating furnace, vacuum furnace, monocrystalline silicon, polysilicon, semiconductor and other industrial temperature measurement.
