What is the importance of arc gear pump flow?
Matters needing attention when using YCB series arc gear pump (1) Disassembly and assembly, according to the total assembly drawings. (2) In and out of the pipeline should not be sharp turn to prevent clogging. (3) master YCB series arc gear pump operation cycle replacement bearing, to prevent accidents. (4) stop the pump when the water rinse release net to prevent winter frost crack. (5) Should be adjusted in the YCB series circular arc gear pump technology used in order to achieve economic and durable. (6) In order to prevent the top of the bad bearing frame, press the motor, the pre-measured pump coupling. YCB series circular arc gear pump is suitable for transporting solid particles and fibers without corrosive, the temperature is not higher than 80 ℃, the viscosity is 5 × 10-6 ~ 1.5 × 10-3m2 / s (5-1500cSt) Lubricants or other liquids of a similar nature as lubricants, as well as for hydraulic drive systems. YCB series arc gear pump applications in the oil transmission system can be used as transmission, booster pump; In the fuel system can be used as delivery, pressurization, injection fuel pump; hydraulic transmission system can be used to provide hydraulic Power hydraulic pump; in all industrial areas, can be used for lubricating oil pump. YCB series arc gear pump gear, shaft, pump body, pump cover, bearing sleeve, shaft seal and other components. Gear with double arc sinusoidal tooth shape manufacturing. Compared with the involute gear, it has the most prominent advantage that the tooth profile has no relative sliding during gear meshing. Therefore, the tooth surface has no wear, stable operation, no fluid due to low noise, long service life and high efficiency. The pump out of the shackles of the traditional design, making the gear pump in the design, production and use into a new field. Pump with safety valve as overload protection, safety valve full back pressure of the pump rated discharge pressure of 1.5 times. Can also be allowed to discharge pressure within the scope of the actual need to be adjusted. But note that the safety valve can not be a long-term work of the valve, if necessary, can be installed separately in the pipeline. The importance of arc gear pump flow What is the basis for arc gear pump selection Pump selection basis, should be based on process, water supply and drainage requirements, to be considered from five aspects, namely, liquid delivery capacity, the device lift, the nature of the liquid , Piping layout and operating conditions. 1, the flow rate is one of the important performance of the election pump data, which 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, taking into account the normal flow, in the absence of maximum flow, usually desirable 1.1 times the normal flow as the maximum flow. 2, the lift system required for installation of the pump is another important performance data, generally to enlarge the 5% -10% head lift to choose. 3, 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 gap or continuous, the pump position is fixed Or removable. 4, the liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties, the physical properties of the temperature c density d, viscosity u, medium particle diameter and gas content, etc., which involves the system lift, effective gas Erosion margin calculation and the type of suitable pump: Chemical nature, mainly refers to the liquid medium chemical corrosion and toxicity, is the selection of pump materials and choose an important basis for the type of shaft seal. 5, the installation of piping system conditions refers to the liquid from the height of the liquid from the liquid to the suction side, such as suction side of the lowest level, the discharge side of the highest level of some data and pipeline specifications and length, material, pipe specifications, the number , Etc., in order to carry out the Department of combing head calculation and NPSH check.
