2CY, KCB gear pump structure instructions

2CY, KCB gear pump from the pump, gear, before and after the pump cover, safety valve, bearings and seals and other zero, components. 1, pump body, front and back cover and other parts of gray cast iron, gear made of high quality carbon steel; can also be based on user needs with copper or stainless steel. 2, safety valve. 2CY series gear pump itself does not have a safety valve, users need to install their own safety valve in the pipeline system. KCB, 2CY series gear pump installed in the rear pump cover or pump body above the safety valve, pump or discharge pipe failure or the discharge valve is completely closed to produce high pressure and high pressure impact valve will automatically open, remove part or All of the high-pressure liquid is returned to the suction chamber, thus protecting the pump and the pipe. 3, bearing. 2CY series gear pump all use DU bearings; tin bronze bearings can be used according to user requirements. 18.3-83.3,2CY1.1 gear pump with DU bearings; can be used according to user requirements tin bronze bearings. KCB133-960,2CY8-60 gear pump with DU bearings, bronze bearings and rolling bearing three structures, to be specified when ordering. DU orders when ordering are not specified supplier. Bearing built-in type, relying on the transmission medium lubrication; 011 bearings and bronze bronze bearings in non-lubricated medium work. 4, shaft seal. 2CY series gear pump shaft seal has a skeleton oil seal, mechanical seal and packing seal three structures. a. Skeletal Oil Seal: Skeletal oil seal is characterized by maintenance, easy replacement, low cost, but shorter life expectancy. NBR frame oil seal is suitable for 1001: the following working environment; FKM oil seal is suitable for the following 200 ℃ working environment. b.1 mechanical seal: mechanical seal is characterized by reliable sealing, long life, high cost. The base of the mechanical seal is made of stainless steel. The different media of the dynamic and static rings are respectively made of YG8 cemented carbide or YG8-graphite, and the working temperature is below 200 ℃. c. packing seal: packing seal is only used for high temperature pump, which is characterized by high temperature, a small amount of leakage. The use of the process need to be adjusted according to the leakage conditions, the use of temperature at 250 ℃: the following. What kind of sealing structure the user needs to be specified when ordering. All orders are not specified by the NBR frame oil seal structure supplier. 5, into and out of the oil port type: 2CY series gear pump inlet and outlet port diameter corresponding to the British pipe thread (G), directly in the pump body. KCB18.3-200,2CY1.1-12 gear pump with pipe threaded mouth of the waist-shaped flange; the remaining pump is not equipped with flanges, when the user needs to be equipped with flange, it should be specified in the order. 6, pump and motor with flexible coupling connection, and installed in the public chassis.

Concave Grating

Reflective Concave Blazed Holographic Gratings
Concave Gratings are critical components in a variety of spectroscopic instrumentation.They are quite useful in analytical instruments,ranging from food analysis to plastics manufacturing and process quality assurance.They are also ideal for applications in optical communications,biotechnology, colorimetry,chromatography,and medical instrumentation.

China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300x300mm2 for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns.
