high pressure washer, hyper pressure cleaning pump

high pressure washer , High pressure cleaning pump unit, portable or stationary, has two kind of transition devices: transmitting belt or inner-placed gear box. Max pressure:200MPa. 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. It is an excellent cleaning device for mechanical equipment and metal structures. Assembly type: horizontal or vertical. Transmission type: electric motor or diesel; There are 4 ways of speed regulation,ie: by gear box, belt wheel, electromagnetic or frequency-changing. Main parts: Pump body:(material used: HT250) Fluid cylinder body: (material used: 304ss,316ss,316L ss, 2205,630ss(17-4PH),1Cr18Ni9Ti, 420ss,4135,4140,1045, Nickel-phosphorus alloy galvanized carbon steel layer) Heat treatment is applied to prevent fatigue crack. Crank shaft (material used: 4135, 4140,QT800,) Nitrogen hardening treatment is applied to attain strong strength, high hardness, durable and corrosion resistant feature. Plunger (material used: superior ceramic, Colmonoy coated,Tungsten carbide coated wear resistant and anti-corrosive layer). Packing seal: Aramid fiber ,Kevlar or carbon constructional fiber are used. Splashing lubrication & Forced lubrication is used. Suction and discharge valves types: conical valve, plate valve, ARN valve ,sphericalvalve and combined valves. They are wear resistant and anti-corrosive after special treatment.
