山東裝載機(jī)在磨合期有啥特點(diǎn)？

山東裝載機(jī)的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)。下面小編為大家介紹山東裝載機(jī)的磨合期的特點(diǎn)。The running in period of Shandong loader is an important link to ensure the normal operation of the loader, reduce the failure rate and prolong its service life. The following small series for you to introduce the characteristics of the running in period of the loader in Shandong.

1.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。Fast wear. Due to the influence of the machining, assembly and adjustment of the new machine parts, the friction surface is rough, the contact area of the surface is small, and the pressure condition of the surface is uneven. In the process of machine operation, the concave and convex parts of the parts are fitted with friction, and the metal debris which is worn down and is used as the abrasive material to continue to participate in the friction, and the wear of the parts matched with the surface is accelerated.

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(脂)不易在摩擦表面形成均勻的油膜以阻止磨損。Bad lubrication. As the assembly of the new assembly clearance is small, and due to assembly and other reasons, it is difficult to guarantee the uniformity of the clearance, the oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear and tear.

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)。Loosening occurred. The new processing assembly parts, with the size of the existing geometry and deviation, in the initial stage, due to shock, vibration and impact of alternating load, heating, deformation and other factors, such as excessive wear and easy, so that the original fastening parts loosening.

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(滲)油(水)，因此，磨合期容易出現(xiàn)滲漏現(xiàn)象。Leakage phenomenon. Due to the influence of mechanical loosening, vibration machine heating, sealing surface machine and pipe joint out leakage, part of casting and machining defects such as difficult to find in assembling and debugging, but because of vibration, the working process of the impact, the defects will be exposed, as leakage (infiltration) oil (water), therefore, prone to leakage in.
