夏季即將來臨，應(yīng)怎樣做好挖沙船的高溫防護(hù)工作？
隨著氣溫的升高，鳥語花香的春天已經(jīng)進(jìn)入了末尾，夏季即將來臨，這正好是挖沙船的運(yùn)作高峰期，但是在夏季這個高溫的季節(jié)，對于挖沙船來說，本身就是一個嚴(yán)峻的考驗。所以用戶必須做好防護(hù)措施，以保證挖沙船即使在溫度較高的情況下也能正常運(yùn)作。因此我們就需要對挖沙船的一些部件進(jìn)行特定的防護(hù)，統(tǒng)一重工小編今天在這就為大家講述一下怎樣做好挖沙船的高溫防護(hù)工作.
在使用過程中為了保證整機(jī)的正常使用，挖沙船在啟動前要檢查風(fēng)扇膠帶的張力情況，發(fā)現(xiàn)松動應(yīng)及時進(jìn)行調(diào)整，而且挖沙船的運(yùn)行過程中要時刻注意水溫表的讀數(shù)變化，達(dá)到90°以上時必須采取措施，可以選擇就近的陰涼處停機(jī)并怠速降溫，注意不要即刻熄火，以防止發(fā)動機(jī)內(nèi)部過熱而造成拉缸等事故。等待溫度降下來后，我們應(yīng)進(jìn)一步檢查風(fēng)扇膠帶的張力情況。
在進(jìn)入夏季之前，我們需要有針對性的對挖沙船潤滑系統(tǒng)的各個部件做一次性能檢測，以使機(jī)油壓力表、變速箱壓力表指示準(zhǔn)確，發(fā)現(xiàn)壓力表指示異常，必須停機(jī)檢查進(jìn)行消缺，確保壓力表指示數(shù)據(jù)的真實、有效。然后我們還要檢查水箱連接的上下水管，由于水箱的上下管的耐油性差，容易早期損壞，從而會影響供水量和發(fā)動機(jī)溫度升過高。及時檢查是否有破裂和漏水現(xiàn)象，要及時排除。同時要保持足量的冷卻水，發(fā)現(xiàn)不足要及時添加。
在夏季這個高溫的季節(jié)長時間的挖沙作業(yè)會使制動轂和制動片的溫度過高，從而造成制動性能下降，因此要隨時檢查挖沙船的制動效能，以便提早發(fā)現(xiàn)并排除制動系統(tǒng)存在的故障，減少事故隱患。一旦出現(xiàn)上述問題應(yīng)該立即停機(jī)降溫，以免給挖沙船的挖沙作業(yè)帶來安全隱患，但絕不能使用冷水來對制動器進(jìn)行強(qiáng)制降溫。
As the temperature rises, the spring of the flowers has entered the end, the summer is approaching, this is precisely the operation of dredging Sand peak, but in the summer of this high temperature season, for the dredging of sand, itself is a grim test. Therefore, users must do a good job of protection to ensure that dredging vessels even in high temperature conditions can operate normally. So we need to dig some of the parts of the sand specific protection, unified heavy industry, today in this for you to tell about how to do the high-temperature protection of dredging sand work.
Firstly, the fan drive belt of dredging barge will produce fatigue, distortion and reduce cooling effect after long use. Therefore, it should be replaced promptly. To replace the tape, pay attention to the model and length, and check the adjustment of its tightness. Secondly, the cooling system of dredging vessels (water-cooled, air-cooled), lubrication system is focused on inspection, through routine point inspection, weekly inspection and professional spot checks, and the cooling system and lubrication system of the various components thoroughly cleaned up, fastening and lubrication, as far as possible to clean up the cooling system scale, to improve the cooling effect, to keep the cool system smooth and accelerate the cooling water cycle;
In the use of the process in order to ensure the normal use of the machine, dredging sand before starting to check the tension of the fan tape, found that loosening should be timely adjustments, and digging sand in the operation of the time to pay attention to the temperature meter reading changes, reaching 90 ° above must take measures, can choose the nearest cool down and idle speed cooling, attention do not immediately flameout, to prevent internal overheating and caused by the engine and other accidents. After waiting for the temperature to drop, we should further inspect the tension of the fan tape.
Before entering the summer, we need to have targeted to dig sand lubrication system components to do a performance test, to make the oil pressure gauge, gearbox pressure gauge to indicate accurate, and found that the pressure gauge indicates abnormal, must be stopped checking to make sure that the pressure gauge indicates the true and effective data. Then we also want to inspect the water tank connected to the upper and lower water pipes, because of the tank's upper and lower oil resistance, easy early damage, which will affect the water supply and engine temperature rise too high. Timely check whether there is a breakdown and leakage phenomenon, to be promptly excluded. At the same time to maintain sufficient amount of cooling water, found that insufficient to add in time.
In summer this high temperature season long time to dig sand operation will make the brake hub and brake pads too high temperature, resulting in a decline in braking performance, so it is necessary to inspect the brake effectiveness of dredging vessels, so as to early detection and elimination of the brake system of the failure to reduce the accident. Once the above-mentioned problems should be immediately down to cool, lest the dredging of sand dredging work to bring safety hazards, but must not use cold water to the brakes to force cooling.
