Lub luag haujlwm ntawm lub tog raj kheej piston pas nrig ua haujlwm yog qhov loj. Nws yog feem ntau dov los txhim kho qhov zoo ntawm cov khoom, thiab nws kuj yog ib qho kev txav mus los nrog cov kev xav tau siab. Lub piston pas nrig yog ib qho txuas ntxiv uas txhawb nqa kev ua haujlwm ntawm lub piston, thiab feem ntau yog siv nyob rau hauv nruab nrab ntawm cov lus tsa suab ua haujlwm ntawm cov roj kheej kheej thiab lub tog raj kheej. Nyob rau hauv kev sib raug zoo rau lwm qhov chaw txav, tus pas nrig piston yog ib qho kev txav nrog kev txav mus los thiab kev ua haujlwm siab.
Lub tog raj kheej piston pas nrig yog tsim los ntawm lub tog raj kheej kheej kheej, lub piston pas nrig, lub tog raj kheej pas nrig, lub piston thiab lub hau kawg. Nws qhov roughness yuav tsum ncav cuag Ra0.4-0.8um, thiab yuav tsum muaj cov kev cai rau coaxiality thiab hnav tsis kam. Lawv tag nrho hnyav. Tsis tas li ntawd, lub machining ntawm slender shafts zoo li lub tog raj kheej rods yeej ib txwm muaj teeb meem loj rau cov neeg ua haujlwm. Yog li ntawd, cov kev xav tau ntawm piston pas nrig hauv kev ua haujlwm yog qhov tseem ceeb ntawm nws. Nws tuaj yeem hais tias qhov ua tau zoo ntawm cov tshuab ua haujlwm tsuas yog cuam tshuam rau qhov zoo thiab kev pabcuam lub neej ntawm cov khoom.
The piston rod of the oil cylinder is an important part of the oil cylinder. It is usually made of 45 steel as a solid rod or an empty tube. The piston rod will be eroded by abrasive particles during use, which is very easy to wear. The current domestic ancient process is to hard chrome plating (coating thickness 0.030.05mm) and polishing, and its surface roughness Ra is 0.10.2μm. The plating solution is based on chromic acid and sulfuric acid as the catalyst. The advantages of the process are: the plating solution is stable, easy to operate, the quality of the surface chrome coating is relatively high, and the oil pole is bright, high hardness, and excellent wear resistance.
Kev ua haujlwm zoo ntawm piston pas nrig tuaj yeem cuam tshuam rau qhov zoo ntawm cov khoom, yog li ua tib zoo saib thaum xaiv, kev ua haujlwm ntawm tus pas nrig piston tuaj yeem txhim kho qhov kev yaig tsis kam, thiab piston pas nrig tuaj yeem ncua sijhawm tiam lossis nthuav tawm ntawm kev qaug zog tawg, yog li txhim kho. lub zog qaug zog ntawm lub tog raj kheej pas nrig. .
Los ntawm yob txoj kev, ib tug txias - ua hauj lwm nyuaj txheej yog tsim nyob rau hauv dov nto, uas yuav txo tau cov elastic thiab yas deformation ntawm kev sib cuag nto ntawm lub sib tsoo khub, yog li txhim kho qhov hnav tsis kam ntawm lub tog raj kheej pas nrig thiab zam kev kub hnyiab los ntawm kev sib tsoo. Tom qab dov, qhov txo qis ntawm qhov roughness tus nqi tuaj yeem txhim kho cov khoom sib xws. Nws yog ib qho tsim nyog yuav tsum paub tias piston pas nrig tuaj yeem luv lossis ntev nyob rau sab hauv ntawm tus pas nrig reciprocating piston, thiab nws txoj kev ntseeg tau ncaj qha cuam tshuam rau kev ua haujlwm ntawm lub compressor. Yog li ntawd, qhov teeb meem ntawm qhov invalidity ntawm tus pas nrig piston kuj yog qhov tseeb. Muaj ntau qhov laj thawj rau qhov tsis raug ntawm lub piston pas nrig ntawm chrome-plated pas nrig chaw tsim khoom, xws li kev ua haujlwm tsis zoo, kev kho cua sov tsis zoo thiab lwm yam.
