Multi-stage pump in fertile Pump Figure D series multi-stage pumps

Hebei fertile Pump Co., Ltd. to provide quality service and quality of performance, Hebei fertile pumps using high-quality materials, carefully designed, make proper use of and to care, Hebei fertile pumps durable, long life, please contact us! ! ! Multi-stage pump disassembly should be strictly protected manufacturing precision parts from damage: wear rod while disassembling the middle of each pad paving should avoid all loose spigot in the middle of the shaft sinking bent note 亊 items:? A, the The liquid pump housing let go b, if the bearing member is a lubricating oil lubrication should let go of the C, removed hinder disassembly of associated pipelines, such as the balance pipe, water pipe lines and lead seal Hebei Wo Industrial Pump Factory Main large flow single-stage double-suction centrifugal pumps, Francis pumps, wearable slurry pump, power plant desulfurization pumps, mining multistage centrifugal pump, filter feed pumps, pipes direct the pump, stainless steel chemical centrifugal pump, pump mechanical seal, diesel pump units and other products, and contract non-standard pumps and accessories design, production and processing, water treatment engineering design. Reputation first, quality assurance, prompt delivery. Welcome friends to negotiate business. Water pump bearing disassembly should be noted: (1) the drag force due to continue until the extent, for example, when installing the bearing screw just installed to stop urging the correct position when the bearing, guarantee rings (washers) of shoulder end by the end surface of the block housing bore or shaft, neither packed too tight, you can not pretend not in place. (2) by urging force as the axis of oil-free bearings, plastic pump which requires the application of force point symmetrical and smooth, spherical or parallel to the axis by urging. (3) to avoid biasing the rolling elements pass through the inner urging, which requires detachable inner diaphragm (shaft washer), the assembly and disassembly of the outer ring when) by urging the outer ring. Smooth (4) urging the size should be uniform and should not have impact, pump which requires the use of hydraulic tools or by applying steady tensile or pressure, when it had to use a hammer, but also through the copper sleeve, etc. relatively soft but not falling scrap metal to the buffer, the striking force gently as possible. Best to use copper or copper hammer hammering. Multi-stage pump in the process of running, and will be subject to external factors affect their factors such as liquid temperature, lift height, etc. These factors will directly affect the efficiency of the multi-stage pump level and fertile life of Hebei Pump Co., Ltd. Related technical staff through years of practice summed up some of the fundamental factors, the following of these factors in detail, so that after the use of multi-stage pump when to minimize and avoid the negative impact of these factors on the multi-stage pump. (1) the nature of the pumped media (eg water quality) is good or bad has a great impact on the multi-stage pump, and wherein the wearing parts, generally turbid liquid to seal very destructive. (2) Suction have a significant impact on the multi-stage pump, the greater the flow tube pressure suction pumps are affected. (3) Head great influence on the level of the multi-stage pump load. Multi-stage pump head higher loss greater. (4) Piping unreasonable to cause great loss of reactive power. (5) Cavitation on Shanghai titanium Dragons multistage pump very destructive. (6) a liquid temperature, ambient temperature has an impact on the multi-stage pump, the average temperature has exceeded the maximum temperature to withstand the multi-stage pump, the pump will burn, (7) vibration damage to the multi-stage centrifugal good great Therefore, the general pump should minimize pump vibration. (8) Install multistage centrifugal influence is also great, as the motor center height deviation large horizontal tilt and so on. (9) supporting the motor speed ratio as unreasonable and irrational will affect the efficiency and life of the multi-stage pump. Multi-stage pump to improve the efficiency of his work, it is necessary reasonable assembly, regular inspection of the working environment, to reduce or avoid those negative factors mentioned above.
