磨合期是保證裝載機(jī)正常運(yùn)轉(zhuǎn)、降低故障率、延長(zhǎng)其使用壽命的重要環(huán)節(jié),對(duì)裝載機(jī)磨合期的適用與保養(yǎng)應(yīng)引起充分重視,在此之前我們應(yīng)該了解磨合期有啊很么特點(diǎn),以便更好的對(duì)裝載機(jī)進(jìn)行維護(hù)。
1、操作失誤多
由于對(duì)機(jī)器的結(jié)構(gòu)、性能的了解不夠,容易因操作失誤引起故障,甚至引起機(jī)械事故。
As the understanding of the structure and performance of the machine is not enough, susceptible to failures caused by operational errors, and even cause mechanical accident.
2、潤(rùn)滑不良
由于新裝配的零部件的配合間隙較小,并且由于裝配等原因,很難保證配合間隙的均勻性,潤(rùn)滑油不易在摩擦表面形成均勻的油膜以阻止磨損。從而降低潤(rùn)滑效能,造成機(jī)件的早期異常磨損。嚴(yán)重時(shí)會(huì)造成精密配合的摩擦表面劃傷或咬合現(xiàn)象,導(dǎo)致故障的發(fā)生。
Since the new assembly parts with the gap is small, and due to assembly and other reasons, it is difficult to ensure uniformity with the gap, the lubricating oil on the friction surface is not easy to form a uniform film to prevent wear. Thereby reducing the lubrication performance, resulting in the early parts of abnormal wear. Will cause serious friction with precision surface scratches or bite phenomenon, leading to failure.
3、發(fā)生松動(dòng)
新加工裝配的零部件,存在幾何形狀和配合尺寸的偏差,在使用初期,由于受到?jīng)_擊、振動(dòng)等交變負(fù)荷,以及受熱、變形等因素的影響,加上磨損過(guò)快等原因,容易使原來(lái)緊固的零部件產(chǎn)生松動(dòng)。
The new processing and assembly of components, there is a deviation geometry and with the size of the initial use, due to shock, vibration, etc. alternating load, and the effects of heat, deformation and other factors, coupled with excessive wear and other reasons, easy to make original loosening the fastening parts.
4、發(fā)生滲漏現(xiàn)象
由于機(jī)件的松動(dòng)、振動(dòng)合機(jī)器受熱的影響,機(jī)器的密封面以及管接頭登出會(huì)出現(xiàn)滲漏現(xiàn)象,部分鑄造、加工等缺陷在裝配調(diào)試時(shí)難于發(fā)現(xiàn),但由于作業(yè)過(guò)程中的振動(dòng)、沖擊作用,這種缺陷就被暴露出來(lái),表現(xiàn)為漏油,因此,磨合期容易出現(xiàn)滲漏現(xiàn)象。
Since the sealing surface of the fitting parts and loose, vibration combined heat machine, the machine will be logged off leakage, part of the casting defects in the assembly and processing debugging difficult to find, but during the operation of the vibration, shock, role of this flaw is exposed, the performance of oil, therefore, prone to leakage of the run.
5、磨損速度快
由于新機(jī)器零部件加工、裝配和調(diào)整等因素的影響,其摩擦表面粗糙,配合面接觸面積小,表面的承壓狀況不均。機(jī)器在運(yùn)行過(guò)程中,零件表面的凹凸部分相互嵌合摩擦,磨落下來(lái)的金屬碎屑又作為磨料繼續(xù)參與摩擦,更加速了零件配合表面的磨損。因此,磨合期內(nèi)容易造成零部件的磨損,磨損速度快。這時(shí),如果超負(fù)荷作業(yè),則可能導(dǎo)致零部件的損壞,產(chǎn)生早期故障。
As the impact of the new machine parts processing, assembly and adjustment factors, the friction surface is rough, with surface contact area is small, uneven surface pressure situation. The machine during operation, some parts convex surface friction fitted into each other, grinding down to the metal debris and continue to participate as an abrasive friction, more accelerated wear parts with surfaces. Therefore, run-in period is likely to cause wear and tear parts, wear faster. At this time, if overload operation, it may cause damage to the components, resulting in premature failure.
