High-temperature heat-conducting oil pump with self-heating cooling structure, changing the traditional water cooling structure, so that the structure is simple, small size, economical operation, good performance, reliable use, is China's digestion and absorption of foreign oil pump developed based on the second generation of products , The basic structure of single-stage single-suction cantilever foot support structure, the pump inlet for the axial suction, the outlet for the central vertical upward, and the same motor mounted on the base. Heat transfer oil pump selection basis, should be based on process, water supply and drainage requirements, to be considered from five aspects, both liquid delivery capacity, device lift, liquid properties, piping layout and operating conditions. First, the installation system required lift is another important performance pump election performance data, generally to enlarge the 5% -10% head lift to choose. Second, the liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties, the physical properties of temperature c density d, viscosity u, medium particle diameter and gas content, etc., which involves the system lift, effective gas Erosion margin calculation and type of suitable pump: Chemical nature, mainly refers to the liquid medium of chemical corrosion and toxicity, is the choice of high temperature heat pump material and the choice of an important basis for the type of shaft seal. Third, the flow rate is one of the important performance data of heat pump, it is directly related to the entire plant's production capacity and delivery capacity. Such as the design process can be calculated in the pump normal, minimum, maximum three kinds of flow. Select the pump, based on the maximum flow, take into account the normal flow, in the absence of the maximum flow, it is usually desirable 1.1 times the normal flow as the maximum flow. Fourth, the operating conditions are many, such as the operation of the liquid T saturated steam P, suction side pressure PS (absolute), the discharge side of the container pressure PZ, altitude, ambient temperature operation is the gap or continuous, high temperature heat transfer oil pump position Is fixed or removable? Fifth, the installation of piping system conditions refers to the liquid from the height of the liquid into the liquid distance to the suction side, such as the lowest level, the highest level of the discharge side of some data and pipe specifications and the length, material, pipe specifications, the number , Etc., in order to carry on the system head calculation and the check of the cavitation allowance.
DSPOF is the biggest manufacturer of raw fibre for lighting in the China. Our manufacturing team have years of experience in building, randomising and polishing. This means you can be sure that you are purchasing a top quality product.
There are two general types of harnesses available - end lit or side emitting types.
Harnesses comprise one or more tails (or cables) of fibre optics which transmit the light from the light source over a distance.
