壓濾機(jī)泵流量揚(yáng)程選擇
在設(shè)計(jì)壓濾機(jī)-泵時(shí)參考了國(guó)內(nèi)主流的壓濾機(jī)設(shè)備，并結(jié)合了多年來客戶的使用情況，設(shè)定了幾種常用的壓濾機(jī)泵型，其流量揚(yáng)程能夠滿足市場(chǎng)通用的各種型號(hào)壓濾機(jī)。
在不同型號(hào)間選擇時(shí)，應(yīng)遵循選大不選小原則，因?yàn)樾吞?hào)大的泵初始流量大，有利于壓濾機(jī)初期快速均勻布料，提高生產(chǎn)效率，防止物料分布不均造成后期壓力不穩(wěn)定對(duì)設(shè)備造成影響。
另外選擇泵的壓濾機(jī)泵壓力時(shí)要看揚(yáng)程高點(diǎn)的壓力，此時(shí)的壓力為壓濾機(jī)壓榨期的泵的工作壓力，也是泵輸出的大壓力值。
壓濾機(jī)泵selection of flow head for feed pump of filter press
in the design of the spe-l pump for filter press，壓濾機(jī)泵圖紙， the domestic mainstream filter press equipment was culted，&combined with the use of customers for many years， several common types of filter press pump were set up， whose flow head can meet the needs of various types of filter press commonly used in the market.
when choosing different models， we should follow the principle of choosing big ones instead of small ones， because the initial flow rate of large pumps is large， which is benefi-l to the rapid&uniform distribution of materials in the initial stage of filter press，壓濾機(jī)給料泵選型， to improve production efficiency，&to prevent the influence of unstable pressure in the later stage caused by uneven distribution of materials on the equipment.
in addition， when choosing the pressure of the pump， it depends on the pressure of the highest point of the lift. at this time， the pressure is the working pressure of the pump during the press period of the filter press，&also the maximum pressure value of the output of the pump.
壓濾機(jī)泵葉輪在損壞不太-的情況下，可進(jìn)行維修處理后二次使用，維修費(fèi)用一般較低，減少企業(yè)的配件更換成本，避免浪費(fèi)。
壓濾機(jī)泵葉輪維修雖然成本低，但是多數(shù)情況下都需要更換新的葉輪。只有在腐蝕、磨損不-，沒有開裂，不變形，表面存在溝痕、條痕、砂眼等的情況下，才可進(jìn)行維修處理。葉輪的修補(bǔ)方法有很多，常見的是焊接修補(bǔ)法，部分情況還可以采用材料填充、鑲嵌的方法。
壓濾機(jī)泵堆焊修補(bǔ)法
堆焊前，用砂輪機(jī)打磨空蝕部位，清理表面的鐵銹、雜物，直至露出光亮的金屬本體，以使堆焊層和葉片結(jié)合牢固。清理后，將葉輪放入炭火中進(jìn)行預(yù)熱。采用和葉片材質(zhì)相同的焊條或不銹鋼焊條，要不脫皮、不破損，保持干燥，去除水分，以免堆焊中產(chǎn)生氣孔。堆焊時(shí)，要采取往返焊，也可采取分層交叉壓焊，每次堆焊量要少，防止葉片受熱集中，產(chǎn)生應(yīng)力變形。補(bǔ)焊后，用磨光機(jī)對(duì)葉片進(jìn)行修整。
