           适用于油田及矿场注水泵、超高压泵、喷射泵，除鳞泵、高压清洗泵，加湿泵，喷雾泵，流程泵、稠浆泵、泥浆泵、液态二氧化碳泵、洗涤剂料浆泵、化工泵、液压泵、输油泵，海水泵等专业用泵。 特 点：　该泵吸收国内泵业之精华，设计先进、结构紧凑、体积小、泵效高、运行平稳、安全可靠、操作简便、产品制作精良、外形美观。每个品种的泵都有安全调压阀，泵压可以任意调节，并有油温、压力、自动保护。 结构型式：固定式、移动式 泵体结构：卧式、立式 传动型式：电机或柴油机，变速型式：皮带、齿轮、电磁调速、变频速、 主要零部件：机座（材料HT250）；泵体（材料：316、1Cr18Ni9Ti、2Cr13、 碳钢化镀镍-磷合金防腐层）经热处理，避免疲劳破裂；曲轴（材料：35CRMo、42CRMo）经调质硬氮化处理、强度大、硬度高、耐磨耐用；柱塞（材料：超性陶瓷、喷焊镍合金Ni60耐磨耐腐层）；盘根密封（采用进口芳纶或碳素纤维）。 阀组型式：锥阀、平板阀、组合阀等。经特殊处理，耐磨耐用。 Water flooding（injection） pump used in oil field Application: To be used as special pump such as water flooding pump used in oil field and mining field, hyper pressure pump, ejection pump, dephosphorizing pump, high pressure cleaning pump, moistening pump, spraying pump, flowing pump, thick mud pump, sludge pump, pump for liquified carbon dioxide, detergent sludge pump, chemical pump, hydraulic pressure pump, oil transition pump, sea water pump etc. Absorbing quintessences of doMEStic pump industries, it has characteristics in advanced design, compact structure and compact pump body, high efficiency, steady run, safe and reliable performance, simple operation, excellent manufacture and nice appearance. There is safety regulating valve in every type of such pump. Pressure can be regulated freely. Oil temperature and pressure are protected automatically. Assembly type: horizontal or vertical. Transition type: electric motor or diesel; There are 4 ways of speed regulation,ie: by gear box, belt wheel, electromagnetic or frequency-changing. MAIn parts: Machine seat (material used: HT250) Pump body (material used: 316, 1Cr18Ni9Ti, 2Cr13, Nickel-phosphorus alloy galvanized carbon steel layer) Heat treatment is applied to prevent fatigue crack. Crank shift (material used: 35CRMo, 42CRMo) Nitrogen hardening treatment is applied to attain strong strength, high hardness, durable and corrosion resistant feature. Plunger (material used: superior ceramic, Ni60 alloy nickel-cOAted wear resistant and anti-corrosive layer). Packing seal Imported imitating polyamide fiber（aramid fiber） or carbon constructional fiber are used. Splashing form of lubrication is used. Valve types: conical valve, plate valve, ARN valve and combined valves. They are wear resistant and anti-corrosive after special treatment. Every pump is equipped with safety regulating valve. Pressure of pump can be regulated freely. Alarm protection for temperature of lubricating oil and inlet and out pressure of the pump are equipped.
