Description
Technical field
The invention belongs to metallurgical material field, particularly steel-bimetal copper-steel rotor and manufacture method thereof for plunger hydraulic pump.
Background technique
Plunger hydraulic pump is by plunger to-and-fro motion in rotor plunger cavity, change plunger cavity volume, realizes oil suction and oil extraction.Because plunger pump has compact structure, rotating speed is high, and flow is large, and efficiency is high, and working pressure is large, easily realizes the advantages such as variable, is widely used in the fields such as engineering machinery, lifting transportation, metallurgy, boats and ships, Aero-Space.
Rotor is crucial friction pair and the heart component of plunger hydraulic pump, and as shown in Figure 1,1 is steel base, and 2 is self-lubricating abrasion-resistant steel antifriction layer.It is bearing the chemical action of alternating stress, impulsive load, Surface Wear and medium, the function of bearing power transmission, lubricating, sealing, and operating conditions is the most severe.The high speed of pump, high-pressure trend will make wearing and tearing, the fatigue problem of crucial friction pair material become more outstanding: at a high speed, surface of friction pair heats up rapidly under high pressure, the faster flow of surface of contact, softening, adhesive wear is aggravated with fatigue damage; The stressed amplitude of friction pair and alternative frequency increase simultaneously, impel material premature failure.In new product development, the heavy wear of crucial friction pair rotor or the fracture that caused by wearing and tearing have become the main cause that pump lost efficacy.Therefore, rotor is the key factor in restriction plunger pump life-span.
The material of manufacturing cylinder block of hydraulic pumps has Cuprum alloy (being mainly Si-Mn brass), iron-base powder metallurgy material, spheroidal graphite cast iron, bimetallic material etc.Wherein, adopt bimetal structure, be that material surface and material matrix are respectively with different materials, the coupling that had so not only met friction pair material requires but also has improved the fatigue strength of material, it is that a kind of friction subsurface performance (material pairing compatibility, antifriction quality, wear resistance) combines with body material mechanical property (intensity, toughness, anti-fatigue ability), the preferred embodiments that solves wearing and tearing and tired dual problem is the method for manufacturing rotor generally adopting.Bimetallic rotor structure is all to adopt copper-steel structure both at home and abroad, and skin-material is that antifriction layer material is all copper base alloy.
But existing copper-bimetal copper-steel rotor can not meet the requirement of a new generation's high speed, high pressure, high-volume hydraulic pump, particularly kerosene pump, and subject matter is:
1. the wear-resisting property of Cuprum alloy antifriction layer is limited.Using maximum antifriction layer materials is at present cast tin bronze ZQSn10-2-3, as cast copper alloy, inevitably there is casting defect, if defect appears at working surface, the surface integrity of meeting destruction work face, reduce greatly the wear-resisting property of rotor wearing layer, make product not reach predetermined life requirements.Compactness after Cuprum alloy casting affects its wear-resisting property, and therefore, its wear resistance is subject to the restriction of foundry engieering.And adopt the manufacture of whole Si-Mn brass, and not only wear-resisting property is undesirable, and intensity is also inadequate, usually occurs that plug pulls phenomenon from ball-and-socket.Particularly when the hydraulic medium of plunger pump is converted to kerosene by chilli oil, just make bimetallic copper alloy layer produce sharp wear, even there is " shaving clearly " phenomenon (be silver plating layer and copper layer are entirely worn away) on bimetal.The heavy wear of rotor end-face copper alloy layer, is damaged sealing surface, cause pump in let out increase, volumetric efficiency declines.If the abrasive dust that Cuprum alloy produces enters hydraulic system, can destroy pump inner assembly, cause significant trouble, greatly reduce working life and the reliability of oil hydraulic pump.
2. the plunger hole of rotor coordinates with plunger, the material that this friction pair should not select heat distortion amount to differ greatly, and this point is particularly outstanding under high-temperature condition.Copper-bimetal copper-steel rotor is different due to thermal expansion coefficient, and heat distortion amount differs greatly, and easily occurs plunger locking, causes the parts such as chuck in pump, piston shoes thoroughly twist off or break, and makes the fault of systemic breakdown.If guarantee the enough amount of deformation of the condition of high temperature, will cause normal temperature state rotor plunger hole and plunger excesssive gap, volumetric efficiency is reduced.Due to the difference of heat distortion amount, rotor, in the process of heat-treating, easily cracks simultaneously.
3. antifriction layer Cuprum alloy easily produces fatigue wear, and copper is transferred in steel base, produces sticky copper, is also " cold welding " phenomenon, affects friction pair and runs well.
4. because the fusing point of Cuprum alloy is low, diffusion welding temperature is restricted, (for example, the σ of ZQSn10-2-3 that adds that the intensity of Cuprum alloy itself is low
bfor 245MPa), therefore, the adhesive strength of copper-bimetal copper-steel friction pair is low, often occurs the situation that end face copper alloy layer comes off and plunger hole copper alloy layer is drawn out.
So far, adopt antifriction, wear-resisting, inadhesion, weldability antifriction layer material good, that can adapt to heat treatment requirements is manufactured bimetallic rotor has become the key that improves plunger hydraulic pump life and reliability.
