YCB stainless steel arc gear pump for mildly corrosive or hygienic conditions at the same time without solid particles and fiber media, the temperature does not exceed 280 â„ƒ, the viscosity of not more than 2000cst of lubricating liquid. For different conditions, can design a variety of stainless steel pump products for different corrosive media. Common stainless steel gear pump main material is 304,316,316 L stainless steel. All stainless steel gear pump parts and components of all the materials through special chemical treatment, with high corrosion resistance, wear resistance and pressure resistance. Stainless steel gear pump main products are forgings products, ordinary sand casting products, casting products and silica sol casting products. The appearance of compact, beautiful, low noise, long life and other characteristics. Is the chemical and corrosive equipment supporting the preferred product. YCB stainless steel arc gear pump adopts internationally the most advanced pump that continuous contact with a little gear, that is, double arc plus sinusoidal compound into tooth shape, can be completely eliminated involute gear pump. Won the national major scientific and technological achievements project, and won the third prize of progress of science and technology by the State Education Commission. YCB stainless steel arc pump in the two meshing tooth profile for a little continuous contact between, will not produce trapped oil phenomenon, completely solve the involute gear pump pump oil vibration, noise, bearing load increases and so on. Therefore, arc gear pump with low efficiency, low noise, and has good energy-saving effect, the use of corrosion-resistant fluorine rubber skeleton oil seal and PTFE packing combination of high temperature sealing, sealing effect, high temperature. Special conditions can be stainless steel corrosion-resistant mechanical seal. Stainless steel gear pump gears are common spur, helical, herringbone, helical teeth, tooth profile are mainly involute and arc type. Usually small gear pump to use more involute spur gear, high temperature gear pump often use variable gear, conveying high viscosity, high pressure melt polymer melt more use of involute helical gears. Gear and shaft made of one, its rigidity and reliability is higher than gear and shaft separately manufactured gear pump. Foreign low-pressure gear pump gear is often used square structure, that gear tooth width equal to the addendum circle diameter. The high-pressure occasions used in high-viscosity gear pump gear tooth width less than its tip diameter, which is to reduce the gear radial compression area, reduce gear, bearing load. Stainless steel gear pump is a new type of liquid conveying machinery, with the advantages of simple structure, safe and reliable operation, convenient use and maintenance, continuous and uniform liquid discharge, and stable pressure. YCB series of stainless steel arc gear pump purposes: Suitable for conveying solid particles and fiber-free, non-corrosive, the temperature is not higher than 80 â„ƒ, the viscosity of 5 Ã— 10-6 ~ 1.5 Ã— 10-3m2 / s (5-1500cSt ) Or other liquids of a similar nature as lubricating oils, as well as for hydraulic drive systems. YCB series stainless steel arc gear pump applications: In the oil transfer 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 as Hydraulic power to provide hydraulic pumps in all areas of industry, can be used for lubricating oil pump. YCB series arc gear pump structural features: This series of 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. Pump shaft seal is designed in two forms, one for the mechanical seal, one is the packing seal, according to the specific use and user requirements. From the spindle extension to the pump to see, clockwise rotation. Stainless steel arc gear pump by relying on the pump cylinder and the meshing gear formed between the volume change and movement to transfer liquid or to booster pump. Stainless steel arc gear pump with external gear double gear pump structure. A pair of intermeshing gears and pump cylinders separate the suction chamber from the discharge chamber. When the gear rotates, the volume of the tooth between the tooth on the suction side and the tooth on the tooth side gradually increases and the pressure decreases, and the liquid enters the space between the teeth under the pressure difference. As the gear rotates, liquid between the teeth is brought to the discharge chamber. At this time, the volume between the teeth on the discharge side of the tooth on the side of the cavity is gradually reduced, and the liquid is discharged. Gear pump is suitable for conveying non-solid particles, non-corrosive, large viscosity range of lubricating liquid. It is commonly used as a hydraulic pump and delivery of various types of oil. Gear pump structure is simple and compact, easy to manufacture, easy to maintain, with good self-absorption capacity, flow, pressure stability. The gear pump must be fitted with a safety valve to prevent damage to the pump or prime mover if the outlet pressure of the pump exceeds the allowable pressure for some reason, such as blockage of the discharge pipe.
