MSH Split Case Pump Size (discharge): 1 inch to 32 inch Capacity: 3.4~ 15000 m3/hr Head: 8.6~140m Efficiency:Up to 92% Materials:Cast iron,SS 304,SS 316,Bronze etc MSH Split Case Pump Introduction: MSH Split Case Pump is Horizontal, Split-casing, and Double-suction centrifugal water pump. Double Volute casing is used to contract the axial force due to high head to extend the serve lift time of bearing. Because of the short distance of two bearing, the shaft is shortened to avoid much vibration.. Closed and Circulated cooling system is applied within the sealing house.The Shaft sleeve and O-ring are used to avoid any connection between the shaft and fluid. MSH Split Case Pump Features: Both inlet and outlet of this pump are placed under the axial line,, the pump casing is opened in the middle so it is unnecessary to remove the water inlet and outlet pipelines and motor.if repaired The pump moves CW viewing from the motor side. The pump moving CCW can also be made . Both pump casing and cover form the working chamber of the impeller and there are threaded holes for mounting vacuum and pressure meters on the flanges ant both inlet and outlet have water draining plug on the lower side of flange The impeller is static-balance and dynamic balance tested, fixed by the the side nuts and the Shaft sleeve nuts and its axial position can be adjusted via the nuts and axial force will be get balanced by means of the symmetrical arrangement of its blades, there may be residual axial force which is borne by the bearing at the axial end. This pump shaft is supported by two centripetal ball bearings, which are mounted inside of the bearing chamber on both ends of the pump and lubricated with grease. The double suction seal ring is used to reduce the leakage.. This pump is driven directly via flexible coupling.(V-belt driving will be available if required). The shaft seal is mechanical seal or packing seal .

Suitable for mine Suitable for water supply and drainage in factory. Suitable for power station. Suitable for urban water supply and drainage Suitable for flood control.
Description Radio Astronomy Antenna The 65-meter radio telescope is an astronomical observation device developed by 54th institute and my company serve for the Shanghai Observatory of the Chinese Academy of Sciences. It is the largest antenna with the highest aperture and accuracy in Asia. It is mainly used in deep space exploration and VLBI orbit determination. Project Overview The 500m aperture spherical radio telescope uses the dimpled surface in the Karst area of Guizhou province as a telescope site to build the world's largest single-caliber radio telescope, which has a big receiving area as large as 30 standard football fields. . The FAST project is about 10 times more sensitive than the 100-meter telescope in Bonn, Germany, which was known as the "biggest ground machine in the world". Compared with the American Arecibo 300-meter telescope which was named "The First of the 10th Mankind Project of the 20th Century," the overall performance is about 10 times improved; FAST�??S mission is to explore the neutral hydrogen in the universe, observe pulsars, leading the international low frequency very long baseline interferometry network, detect interstellar molecules, and search for possible interplanetary communication signals. 65 meter radio telescope The 65-meter telescope uses a modified Cassegrain antenna with a 65 meters aperture , a 70 meters height and a approximately 2,700 tons weight. It can work in the eight frequency bands L, S, C, X, Ku, K, Ka and Q. The bottom working frequency is 1.25 GHz and the maximum operating frequency is 46 GHz. S/X and X/Ka are dual frequency simultaneous observations, and the antenna pointing accuracy is better than 3 arc seconds. With actuator, the working accuracy of the main reflector is less 0.3mm ,0.6mm without. The working accuracy of the subreflector is less than 0.1mm and its adjustment adopts Stewart parallel mechanism, which can accurately correct the error of its position. The 65-meter antenna should maintain high surface accuracy under different angles of pitch. In the design stage, the 65-meter antenna structure performs mechanical simulation analysis using finite element technology under various working postures, only the technical specifications such as stress, strain, resonance frequency, etc meet the requirements the optimal topology and cross-section parameters are obtained. For the first time, the 65-meter antenna has adopted the all-orbit welding technology in China. The track is made of 42CrMo material. The maximum height difference after welding is less than 0.5mm and the surface hardness is HRC48~HRC52.
Description Fixed Antenna The 1.8m aperture antennas panels are base coated with yellow strontium and face coated with polyurethane which is good performance for chemical, biology and nuclear protection.
