如今施工重新開工，攪拌車也開始工作，要注意使用起來(lái)比較麻煩，但是在高溫狀態(tài)下防護(hù)技術(shù)的安全使用我們應(yīng)該做好哪些呢？這不僅可以實(shí)現(xiàn)安全操作，還可以延長(zhǎng)攪拌車的使用壽命。

Now the construction starts again, and the mixer truck also starts to work. It should be noted that it is troublesome to use it, but what should we do well in the safe use of protective technology under high temperature? This can not only achieve safe operation, but also extend the service life of the mixer truck.

進(jìn)入高溫后，有針對(duì)性地對(duì)潤(rùn)滑系統(tǒng)各部件進(jìn)行性能測(cè)試，使油壓表和變速箱壓力表指示準(zhǔn)確。對(duì)變速箱、變槳器和驅(qū)動(dòng)橋的油液進(jìn)行系統(tǒng)檢查，從油液質(zhì)量到油量，保持油液清潔。

After entering the high temperature, carry out targeted performance tests on all components of the lubrication system to make the oil pressure gauge and transmission pressure gauge indicate accurately. Carry out systematic inspection on the oil of transmission, pitch and drive axle, and keep the oil clean from oil quality to oil quantity.

定期檢查整機(jī)制動(dòng)性能，以便盡快發(fā)現(xiàn)和排除制動(dòng)系統(tǒng)故障，降低事故風(fēng)險(xiǎn)。如果長(zhǎng)時(shí)間使用剎車，剎車轂和剎車片的溫度會(huì)過(guò)高，剎車性能會(huì)降低。但切勿讓剎車被迫用冷水冷卻。

Regularly check the braking performance of the whole machine, so as to find and eliminate the faults of the braking system as soon as possible and reduce the risk of accidents. If the brake is used for a long time, the temperature of the brake hub and brake pad will be too high and the braking performance will be reduced. However, do not force the brake to be cooled with cold water.

檢查水泵、風(fēng)扇傳動(dòng)皮帶。皮帶長(zhǎng)時(shí)間使用后，皮帶會(huì)疲勞變形，降低冷卻效果。更換皮帶時(shí)，要注意型號(hào)和長(zhǎng)度，正確調(diào)整松緊度。檢查水箱的連接軟管。水箱軟管的耐油性比較差，容易過(guò)早損壞，從而影響供水，導(dǎo)致發(fā)動(dòng)機(jī)溫度升高過(guò)高。檢查有無(wú)裂紋和滲漏，并及時(shí)清除。同時(shí)要保持足夠的冷卻水量，如發(fā)現(xiàn)不足應(yīng)及時(shí)補(bǔ)充。

Check the water pump and fan drive belt. After long-term use, the belt will be fatigued and deformed, reducing the cooling effect. When replacing the belt, pay attention to the model and length, and correctly adjust the tightness. Check the connecting hose of the water tank. The oil resistance of the water tank hose is relatively poor, which is easy to be damaged early, thus affecting the water supply and causing the engine temperature to rise too high. Check for cracks and leaks and remove them in time. At the same time, sufficient cooling water should be maintained, and if it is found to be insufficient, it should be supplemented in time.

對(duì)自動(dòng)上料攪拌車發(fā)動(dòng)機(jī)也是要十分注意的，溫度的升高會(huì)使發(fā)動(dòng)機(jī)過(guò)熱，因此要對(duì)發(fā)動(dòng)機(jī)的冷卻系統(tǒng)及時(shí)的檢查和保養(yǎng)，比如及時(shí)的給水箱加水，清理散熱器上的灰塵等，當(dāng)水溫超過(guò)100度時(shí)，應(yīng)在陰涼處停車降溫，讓發(fā)動(dòng)機(jī)怠速運(yùn)轉(zhuǎn)，掀起發(fā)動(dòng)機(jī)罩散熱。

We should also pay great attention to the engine of the automatic feeding mixer truck. The increase of temperature will overheat the engine, so we should check and maintain the engine cooling system in time, such as adding water to the water tank in time, cleaning the dust on the radiator, etc. when the water temperature exceeds 100 ℃, we should stop in the shade to cool down, let the engine idle, and lift up the hood to dissipate heat.

溫度的升高會(huì)加速混凝土的凝結(jié)，因此在攪拌車行駛途中，攪拌筒一定不能停轉(zhuǎn)，攪拌筒內(nèi)混凝土中的水分也會(huì)蒸發(fā)，所以要適當(dāng)?shù)慕o混凝土加水，保證它的配比結(jié)構(gòu)不變。

The rise of temperature will accelerate the setting of concrete. Therefore, during the driving of the mixer truck, the mixing drum must not stop running, and the water in the concrete in the mixing drum will also evaporate. Therefore, it is necessary to add water to the concrete appropriately to ensure that its proportioning structure remains unchanged.

氣溫的升高還會(huì)加速燃油的蒸發(fā)，因此容易在油路中造成氣阻，那么我們就必須及時(shí)清洗燃油濾清器，以保證油路暢通。在行車途中一旦燃油系統(tǒng)發(fā)生氣阻，應(yīng)立即停車降溫，并扳動(dòng)手油泵使油路中充溢燃油。

The rise of temperature will also accelerate the evaporation of fuel, so it is easy to cause air resistance in the oil circuit, so we must clean the fuel filter in time to ensure that the oil circuit is unblocked. In case of air blockage in the fuel system during driving, stop immediately to cool down, and turn the hand pump to fill the oil circuit with fuel.
