LYSPS-SP中開泵的選型與報價
. 近年來，我們水泵行業(yè)出現(xiàn)了外觀優(yōu)質(zhì)且運行高效的中開泵產(chǎn)品，如LYSPS-SP型中開泵等型號的水平中開泵產(chǎn)品，對提高LYSPS-SP水平中開泵的效率和降低泵的能源消耗起了積極的作用。但目前在國民經(jīng)濟(jì)的各個領(lǐng)域，由于水泵選型不合理，許多水泵運行不合理，效率低下，浪費大量能源。有的泵由于選型不合理，根本無法使用，或者使用維護(hù)費用增加，造成經(jīng)濟(jì)效益低下。因此，合理選擇中開泵對節(jié)能也具有重要意義。所謂合理選泵，就是綜合考慮水泵機(jī)組和泵站的投資和運行費用等綜合技術(shù)經(jīng)濟(jì)指標(biāo)，使之符合經(jīng)濟(jì)、安全、適用的原則。臥式中開泵是一種通用機(jī)械設(shè)備，廣泛應(yīng)用于石油、化工、電力冶金、礦山、船舶選型、輕工、農(nóng)業(yè)、民防等部門，在國民經(jīng)濟(jì)中占有重要地位。水泵用電量約占全國用電量的21%。因此，降低中開泵的能耗對節(jié)能具有重要意義。上海龍亞泵閥從以下幾個方面： 必須滿足使用流量和揚程的要求，即要求泵的運行工況點(裝置特性曲線 與水泵的性能曲線的交點)經(jīng)常保持在高效區(qū)間運行，這樣既省動力又不易損壞機(jī)件;所選擇的水泵既要體積小、重量輕、造價便宜，又要具有良好的特性和較高的效率;具有良好的抗汽蝕性能，這樣既能減小中開泵泵房的開挖深度，又不使水泵發(fā)生汽蝕，運行平穩(wěn)、壽命長。只有這樣安裝需求選著合適的水平中開泵或其他水泵，才能一步到位，按部就班，把建泵站控制在Z低的成本內(nèi)，工程投資少，運行費用低，而且能達(dá)到Z高的效率。LYSPS-SP中開泵在選型的時候，應(yīng)該選用與實際流量和揚程比較接近的泵浦，型號有LYSPS-710等各種規(guī)格。LYSPS-SP中開泵的報價則一般是根據(jù)中開泵的數(shù)量、流量和揚程而定，流量越高、揚程越高，價格則相對越大。
Type selection and quotation of lysps-sp split pump
In recent years, there are high-quality and high-efficiency pumps in our water pump industry, such as lysps-sp pumps, which play a positive role in improving the efficiency of lysps-sp pumps and reducing the energy consumption of pumps. But at present, in various fields of national economy, due to the unreasonable selection of water pump, many water pumps run irrationally, low efficiency and waste a lot of energy. Some pumps cannot be used at all due to unreasonable selection, or the use and maintenance costs increase, resulting in low economic benefits. Therefore, reasonable selection of water pump is also of great significance to energy saving. The so-called reasonable pump selection is to comprehensively consider the investment and operating costs of pump units and pumping stations and other comprehensive technical and economic indicators, so as to make them conform to the principles of economy, safety and applicability. Horizontal split pump is a kind of general mechanical equipment, which is widely used in petroleum, chemical industry, power metallurgy, mining, ship selection, light industry, agriculture, civil defense and other departments, and plays an important role in the national economy. The electricity consumption of water pumps accounts for about 21% of the national electricity consumption. Therefore, reducing the energy consumption of the pump is of great significance to energy saving. Shanghai Longya pump valve must meet the requirements of flow rate and head, that is, the pump operating point (the intersection of device characteristic curve and pump performance curve) should always be kept in the high efficiency range, so as to save power and not easy to damage the parts; The selected pump should not only have small volume, light weight, low cost, but also have good characteristics and high efficiency; it has good anti cavitation performance, which can not only reduce the excavation depth of the pump house, but also prevent the pump from cavitation, and has stable operation and long service life. Only in this way can we choose the right level of pump or other pumps for installation, and control the construction of pump station in Z low cost step by step, with less project investment, low operation cost and high efficiency. When selecting the type of lysps-sp medium starting pump, it should select the pump which is close to the actual flow and head, and the model has various specifications such as lysps-710. Lysps-sp is generally quoted according to the flow and head of the pump in the pipe. The higher the flow and head, the higher the price.
