夏季即将来临，应怎样做好挖沙船的高温防护工作？
随着气温的升高，鸟语花香的春天已经进入了末尾，夏季即将来临，这正好是挖沙船的运作高峰期，但是在夏季这个高温的季节，对于挖沙船来说，本身就是一个严峻的考验。所以用户必须做好防护措施，以保证挖沙船即使在温度较高的情况下也能正常运作。因此我们就需要对挖沙船的一些部件进行特定的防护，统一重工小编今天在这就为大家讲述一下怎样做好挖沙船的高温防护工作.
在使用过程中为了保证整机的正常使用，挖沙船在启动前要检查风扇胶带的张力情况，发现松动应及时进行调整，而且挖沙船的运行过程中要时刻注意水温表的读数变化，达到90°以上时必须采取措施，可以选择就近的阴凉处停机并怠速降温，注意不要即刻熄火，以防止发动机内部过热而造成拉缸等事故。等待温度降下来后，我们应进一步检查风扇胶带的张力情况。
在进入夏季之前，我们需要有针对性的对挖沙船润滑系统的各个部件做一次性能检测，以使机油压力表、变速箱压力表指示准确，发现压力表指示异常，必须停机检查进行消缺，确保压力表指示数据的真实、有效。然后我们还要检查水箱连接的上下水管，由于水箱的上下管的耐油性差，容易早期损坏，从而会影响供水量和发动机温度升过高。及时检查是否有破裂和漏水现象，要及时排除。同时要保持足量的冷却水，发现不足要及时添加。
在夏季这个高温的季节长时间的挖沙作业会使制动毂和制动片的温度过高，从而造成制动性能下降，因此要随时检查挖沙船的制动效能，以便提早发现并排除制动系统存在的故障，减少事故隐患。一旦出现上述问题应该立即停机降温，以免给挖沙船的挖沙作业带来安全隐患，但绝不能使用冷水来对制动器进行强制降温。
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.
