WL vertical sewage pump technical requirements

WL Assembly vertical sewage pump after the assembly is completed, to conduct performance tests to ensure that the overall performance of the unit in line with the relevant standards, which requires the WL vertical sewage pump technology put forward a higher standard . Then WL vertical sewage pump what technical requirements? Xiaobian give you introduce its technical requirements, as follows: WL vertical sewage pump technical requirements 1, the pump is a single-stage single suction volute vertical Pump, the use of elbow into the water, with a vertical motor through the elastic coupling directly connected with the pump torque transmission. 2, the impeller can pass φ125mm solid particles, using large-channel design, non-blocking, anti-wrap performance. Pump vibration intensity in line with GB10889 C-class regulations, the noise is less than 75 dB, to ensure smooth pump continuous operation. 3, vertical sewage pump epoxy coating anticorrosive paint, the surface bright, no trachoma, cracks, etc., the surface of parts by blasting derusting and degreasing epoxy powder coating. 4, vertical sewage pump impeller, rotor balancing test, the balance accuracy of G6.3 level. 5, vertical pump over-current components and oil chamber to do the pressure test, the test pressure is shut gate lift indeed 1.5 times, lasted 5 minutes without leakage and so on, out of the water flange with standard design, pump and impeller wear Ring, to ensure the sealing performance of the pump, the pump is always in the high-performance area within the scope of operation. 6, vertical pump bearings used for the double row radial ball bearings, to withstand axial force, the use of self-lubricating way, the bearing seat with temperature monitoring sensor can withstand the maximum reverse speed of 130% of rated speed, Rotor shaft axial displacement control within 0.2mm, in line with the use of sealed requirements, will not have harmful effects. 7, pump impeller shaft material 2Cr13 stainless steel, bearings imported bearings, effectively improve the durability and service life of the pump. 8, pump and inlet with access holes, easy access and clean up debris, the outlet is equipped with a pressure gauge pipe screw holes. 9, the pump body with ductile iron, stainless steel alloy impeller material, all stainless steel pump fasteners are used, static sealing material sealed with nitrile rubber. 10, the pump seal mechanical seal with tungsten carbide, the use of reliable long life. 11, The vertical motor adopts Y series motor, the insulation grade is F class, the protection grade is IP44, the motor efficiency is more than or equal to 92%, the power factor is more than or equal to 0.83, the power supply is 380V / 3 / 50Hz, the natural cold air cooling mode implements the standard ZBK22007, The maximum power required for the entire working range of the pump is indeed 0%.

A Noise Barrier (also called a soundwall, sound berm, Sound Barrier, or acoustical barrier) is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution. Noise barriers are the most effective method of mitigating roadway, railway, and industrial noise sources – other than cessation of the source activity or use of source controls.

Specification of sound barrier:
