隨著經(jīng)濟(jì)的快速發(fā)展，建筑行業(yè)異常紅火，投資攪拌車作業(yè)的老板們?yōu)榱吮M快收回成本，追求利益增長的同時會縮短工期，水泥自上料攪拌車日夜連續(xù)作業(yè)，因此，出現(xiàn)了水泥自上料攪拌車的使用問題。自上料水泥攪拌車?yán)鋮s器冷卻效果降低，使油液溫升，系統(tǒng)發(fā)熱冷卻器冷卻效果降低，可能由以下原因引起：

With the rapid development of the economy, the construction industry is booming. In order to recover the cost as soon as possible, the owners who invest in the operation of the mixing truck will shorten the construction period while pursuing the growth of interests. The cement self-loading mixing truck works continuously day and night. Therefore, there is a problem of using the cement self-loading mixing truck. The cooling effect of the cooler of the self-feeding cement mixer truck is reduced, causing the oil temperature to rise, and the cooling effect of the system heating cooler is reduced, which may be caused by the following reasons:

①冷卻器內(nèi)部堵塞或表面污物較多，造成冷卻器裝置開啟，冷卻器過流量降低，使散熱流量減少，或冷卻器通風(fēng)不良，使冷卻器的冷卻傳熱系數(shù)降低，冷卻效果降低，因此，水泥自上料攪拌車在使用中一定要定期檢查，疏通冷卻器，定期對冷卻器表面污物進(jìn)行，保證冷卻器的內(nèi)部暢通和外部清潔，以保證冷卻器的冷卻效果。

① The internal blockage of the cooler or a lot of dirt on the surface will cause the cooler safety device to open, the cooler overflow will be reduced, the cooling flow will be reduced, or the cooler ventilation will be poor, and the cooling heat transfer coefficient of the cooler will be reduced, and the cooling effect will be reduced. Therefore, the cement self-feeding mixer must be regularly checked during use, dredge the cooler, and regularly clean the dirt on the surface of the cooler, Ensure the internal smoothness and external cleanness of the cooler to ensure the cooling effect of the cooler.

②冷卻器閥或單向閥的開啟壓力低于標(biāo)準(zhǔn)值，使冷卻器保護(hù)裝置在冷卻器未堵塞時開啟，產(chǎn)生溢流分流，使冷卻器散熱流量減少，因此，冷卻器在使用前，一定要正確調(diào)整保護(hù)裝置的開啟壓力，在使用中要定期檢查、校正保護(hù)裝置的開啟壓力值。

② The opening pressure of the safety valve or check valve of the cooler is lower than the standard value, which causes the safety protection device of the cooler to open when the cooler is not blocked, resulting in overflow diversion and reducing the cooling flow of the cooler. Therefore, the opening pressure of the safety protection device must be correctly adjusted before the cooler is used, and the opening pressure value of the safety protection device must be regularly checked and corrected during use.

此外水泥自上料攪拌車液壓系統(tǒng)的內(nèi)泄，包括液壓攪拌車、液壓缸、液壓馬達(dá)和液壓閥的內(nèi)泄，壓力油在泄漏過程中，壓力下降，溫度升高。如果系統(tǒng)的內(nèi)泄增加，會引起油溫升高，系統(tǒng)過熱，嚴(yán)重時，會使系統(tǒng)壓力下降，攪拌車送無力，攪拌車送排量降低，攪拌無力，攪拌轉(zhuǎn)速下降等。

In addition, the internal leakage of the hydraulic system of the cement self-feeding mixer truck includes the internal leakage of the hydraulic mixer truck, hydraulic cylinder, hydraulic motor and hydraulic valve. During the leakage of the pressure oil, the pressure drops and the temperature rises. If the internal leakage of the system increases, the oil temperature will rise, the system will overheat, and in serious cases, the system pressure will drop, the mixer truck delivery capacity will be reduced, the mixer truck delivery capacity will be reduced, the mixer will be weak, and the mixing speed will drop.

因此，要定期檢查這些元件，定期更換相應(yīng)的密封元件，及時對已損壞、拉傷的零件進(jìn)行更換或修理，甚更換相應(yīng)的液壓元件，從而避免由于元件泄漏而造成的系統(tǒng)發(fā)熱。更多相關(guān)使用事項就來我們網(wǎng)站http://f3328.cn咨詢吧！

Therefore, these components should be checked regularly, corresponding sealing components should be replaced regularly, damaged and strained parts should be replaced or repaired in time, and even corresponding hydraulic components should be replaced, so as to avoid system heating caused by component leakage.
