Jiangsu Du'an 65-200AThe single-stage horizontal end-suction pump features a rear-hinged door design. The shaft end seal requires a packaged mechanical seal. The primary seal (dynamic and static rings) should be made of high-strength, high-wear-resistant materials. The material, structure, and cooling flushing scheme of the mechanical seal should be reasonable and reliable.
Bearings are standard type rolling bearings, usingNSKOrSKFBrandBasic rating life of roller bearingsNot less than the normal service lifeUnder rated conditions, operate continuously for at least25000 HourPlease provide the Chinese content that needs to be translated into American English.At rated speed under both radial and axial loads, at least16000 Hour(s).
Pump and drive motor transmission connections should be made using a coupling for direct connection, couplingHarvestUtilize couplings with extended hub membranes. The pump shaft must possess adequate strength and rigidity to transmit the rated power of the prime mover; the surface roughness of the shaft and sleeve at the mechanical seal should not exceed0.8mThe shaft deflection must not exceed during operation within the allowable range of the pump.50m。
A replaceable and sturdy locking ring that won't rotate, made of wear-resistant material, should be placed between the impeller and the pump housing to maintain the pump's operation.HighEfficient operation.PumpMechanical seals are used, with the leakage of the mechanical seal not exceeding5mL/h。
WDSSingle-stage horizontal centrifugePump body and cover, including the shaft seal box and sealing end cover, must not exceed the nominal pressure of the pump flange. The pump body, including the shaft seal box and sealing end cover, features sufficient wall thickness for adequate structural integrity.NormalOperating TemperatureOperation.
Pressure gauge fittings should be installed at both the inlet and outlet of the pump body. A vent valve connection should be left at a higher point on the water pump outlet. Liquid drain connections should be set at the lower part or several low points of the pump, and sealed with a bolt plug.
The impeller is made of a single casting, ensuring its structural design guarantees the high-efficiency pumping of flushing water. ImpellerAvailableRigid fixation to prevent circumferential and axial movement during rotation in the specified direction.
A replaceable and sturdy locking ring that won't rotate, made of wear-resistant material, is installed between the impeller and the pump housing to maintain the pump's operation.HighEfficiency in operation.WDSHorizontal CentrifugalThe shaft of the pump has sufficient strength and rigidity to transmit the rated power of the prime mover; the roughness of the shaft and sleeve surfaces at the mechanical seal should not exceed0.8m.Pumps operate within their allowable working range with shaft deflection.GenerallyNo more than50m。
If equipped with a sleeve, it should be securely fastened to prevent movement of the sleeve along the circumference and in the axial direction. The sleeve should be tightly adjacent to the impeller hub to maintain a seal and prevent the shaft from becoming wet. Additionally, it should be ensured that the leakage between the shaft and sleeve does not confuse with the leakage passing through the mechanical seal face.
To prevent loss and contamination, the design of the bearing housing must not use gaskets and threaded joints to isolate the lubricant from the cooling fluid. All openings in the bearing housing should be designed to prevent the entry of debris and leakage under normal operating conditions.
WDSHorizontal CentrifugalThe pump is connected to the driving shaft with an elastic coupling, which is of a size to accommodate the higher torque requirements of the predetermined driving motor. The maximum rotational speed of the coupling matches all possible operating speeds of the pump's driving motor. A protective cover is fitted to the coupling.
The base should be a common base for both the pump and motor, with a design that allows for vertical adjustment of the driving unit to compensate for the tolerances between the pump driving unit and the base.
At any operating point on the pump characteristic curve, the motor's rated output shaft power should be at least greater than the pump shaft power by15%The motor must be designed for continuous operation and must meet a minimum of... per hour.10No startup requirements that would cause any harmful effects. The motor is equipped with overheat and overcurrent protection devices.
