裝載機機油壓力有哪些影響因素？

1、機油油量缺乏若機油油量缺乏，會使機油泵的泵油量削減，致使機油壓力下降，加重曲軸與軸承、缸套與活塞的磨損。
If oil oil oil oil lacking the lack of pumps will pump oil cuts, causing oil pressure drop, increasing crankshaft and bearings, cylinder and piston wear.
2、若發(fā)動機溫度過高，不光加快機油老化、變質(zhì)，也簡單使機油變稀，致使油壓下降。機油泵的驅(qū)動齒輪與驅(qū)動軸的固定銷開裂或合作鍵脫落，以及機油泵吸入異物而將泵油齒輪卡住，都會使機油泵中止工作，機油壓力也隨之降為0。當機油泵泵軸與襯套之間的空隙、齒輪端面與泵蓋的空隙、齒側(cè)空隙或徑向空隙因磨損而超越答應(yīng)值時，都會致使泵油量削減，形成機油壓力下降的結(jié)果。
If the engine temperature is too high, not only to speed up the oil aging, deterioration, but also simple to make oil thinning, resulting in oil pressure drop. Oil pump drive gear and drive shaft fixing pins cracking or cooperation key off, and the oil pump and the pump oil inhaled foreign body stuck in gear, will make the oil pump to suspend work, oil pressure also will be reduced to zero. When the gap between the oil pump shaft and bushing, the gear end and pump cover gaps, voids or radial gap tooth side due to wear and beyond the agreed value will cause the fuel pump to reduce the formation of oil pressure drop results.　　
3、曲軸與連桿軸承合作空隙過大。發(fā)動機長期使用后，曲軸與連桿軸承的合作空隙會逐步增大，機油壓力也隨著下降。
Crankshaft and connecting rod bearings cooperation gap is too large. After long-term use of the engine, crankshaft and connecting rod bearings cooperation gap will gradually increase, along with the oil pressure drops.　　
4、當機油因濾油器阻塞而不能流轉(zhuǎn)時，設(shè)在濾油器底座上的安全閥就被頂開，機油便不經(jīng)過濾而直接進入主油道。假如安全閥的敞開壓力調(diào)得過高，濾油器被阻塞時，安全閥就不能及時翻開，于是機油泵壓力升高，內(nèi)漏添加，主油道供油量削減，引起油壓下降。
When the oil circulation can not be blocked by the oil filter, the oil filter is provided on top of the base of the valve was open, the filtered oil will not directly into the main oil gallery. If the safety valve open pressure adjusted too high, when the oil filter is blocked, the safety valve will not open in time, so the pump pressure increases, the leakage add, the main oil supply reduction, causing oil pressure drop.　
5、機油散熱器及管路漏油，會使油壓下降。管路若被臟物阻塞，也會因阻力增大而使油的流量削減、油壓下降。
Oil radiators and piping oil spills, oil pressure will drop. If they are dirt blocking the pipeline will increase the flow resistance due to cuts leaving the oil, oil pressure drop.
6、若油壓傳感器失靈，或由主油道至油壓傳感器的油管因塵垢積累而流轉(zhuǎn)不暢時，油壓表將顯現(xiàn)機油壓力下降。
If the oil pressure sensor failure, or to the main oil pipeline from the oil pressure sensor, poor circulation due to dirt accumulation, the oil pressure gauge will show the oil pressure drops.
