Features of JZK Series Vacuum Oil Purifier for Insulating Oil Regeneration
The vacuum oil filter absorbs the advanced technology of similar products at home and abroad for innovative design, and has excellent cost performance. In the oil treatment process and equipment performance in the leading level, with a high degree of vacuum, oil filter speed, protection of oil and other advantages, can increase the oil breakdown voltage 35KV. This series of products can be used fixed or trailer movable type, suitable for the installation and repair of large-scale transformer oil handling, vacuum oil transformer and hot oil circulation drying.
JZK series vacuum oil purifier for insulating oil regeneration Features:
1. The machine has a tank body and a two-stage vacuum separation chamber. The inter-stage liquid level is automatically balanced and forms an inter-stage pressure difference. The performance is better than a single-stage vacuum oil filter.
2. The fore pump of the standard configuration of the machine adopts the world-leading European imported vacuum pump (natural cooling method), which has fast pumping speed and can quickly obtain high working vacuum degree.
3. Vacuum separation is a new technology, using a unique stainless steel folding cyclone degassing dehydration separation column, increasing the separation area to make the oil thin film and achieve three-dimensional evaporation to obtain enough vaporization time to ensure the best effect of a separation.
4, the use of new heating devices, low heating load, avoid oil aging.
5, personalized design, users can choose according to the needs of imported or partially imported products,
6, impurity filter are equipped with the United States imported filter material, large filtration area, strong pollution capacity, high filtration accuracy.
7, the machine running low noise, no leakage, long service life.
It is mainly made of a material with high pyroelectric coefficient, such as lead zirconate titanate ceramics, lithium tantalate, triglyceride titanium sulfate, etc. to make the detection element with a size of 2*1mm. Install one or two detection elements in each detector, and connect the two detection elements in series with reverse polarity to suppress the interference caused by the rise of their own temperature. The detection element converts the detected and received infrared radiation into a weak voltage signal, which is amplified by the field effect tube installed in the probe and output outward. In order to improve the detection sensitivity of the detector and increase the detection distance, a Fresnel lens is generally installed in front of the detector. The lens is made of transparent plastic. The upper and lower parts of the lens are divided into several equal parts. It is a kind of lens with a special optical system. It can amplify the signal by more than 70 decibels in cooperation with the amplifying circuit, so that the movement of people within 20 meters can be measured.
The Fresnel lens uses the special optical principle of the lens to produce an alternating "blind zone" and "high-sensitivity zone" in front of the detector to improve its detection and reception sensitivity. When someone walks in front of the lens, the infrared rays emitted by the human body will alternate from the "blind area" to the "high sensitive area", so that the received infrared signal is input in the form of sudden strong and weak pulses, thereby strengthening its energy amplitude .
The central wavelength of infrared radiation radiated by the human body is 9~10--um, and the wavelength sensitivity of the detection element is almost stable in the range of 0.2~20--um. A window equipped with a filter lens is opened at the top of the sensor. The wavelength range of light that this filter can pass is 7~10--um, which is suitable for the detection of human infrared radiation, and other wavelengths of infrared rays are filtered. The sheet is absorbed, thus forming an infrared sensor specially used to detect human body radiation.
