全自動小型混凝土攪拌車滾道與托輪是攪拌車運輸混凝士的重要部件，她的好壞直接影響到車輛的正常運行,下面小編為您講解相關(guān)問題。

The raceway and supporting wheel of the fully automatic small concrete mixer are important parts of the mixer for transporting concrete. Their quality directly affects the normal operation of the vehicle. The following is a brief introduction to relevant issues.

1.硫酸酸洗法

1. Sulfuric acid washing method

攪拌車滾道硫酸酸洗法使用質(zhì)量濃度為50~200克/升的硫酸水溶液，攪拌車滾道酸洗溫度通常在60~80之間。硫酸是一種氧化性酸，其酸洗速度低于鹽酸。有時，為了加快酸洗速度，超聲波可以作為攪拌車滾道清洗輔助手段。

The sulfuric acid pickling method of the mixing car raceway uses sulfuric acid aqueous solution with a mass concentration of 50-200 g/L, and the pickling temperature of the mixing car raceway is usually between 60 and 80. Sulfuric acid is an oxidizing acid, and its pickling speed is lower than hydrochloric acid. Sometimes, in order to speed up the acid cleaning, ultrasonic can be used as an auxiliary means for cleaning the raceway of the mixer truck.

2.鹽酸酸洗

2. Hydrochloric acid pickling

攪拌車滾道鹽酸酸洗法采用質(zhì)量濃度為50~200克/升的鹽酸水溶液，攪拌車滾道酸洗溫度通常在40以下。鹽酸是一種還原性酸，具有很強的酸洗能力。攪拌車滾道清洗使用時，還可能導(dǎo)致氧化皮下金屬基體的過度腐蝕。因此，在攪拌車滾道酸洗過程中經(jīng)常添加尿素來保護金屬基體。

The hydrochloric acid pickling method of the mixing car raceway adopts hydrochloric acid aqueous solution with a mass concentration of 50-200 g/L, and the pickling temperature of the mixing car raceway is usually below 40. Hydrochloric acid is a reducing acid with strong pickling ability. When the mixing truck raceway is cleaned and used, it may also lead to excessive corrosion of the oxidized metal substrate under the skin. Therefore, urea is often added to protect the metal matrix during the pickling process of the mixer raceway.

全自動小型混凝土攪拌車投入使用后,攪拌車滾道與托輪的理想狀態(tài)是經(jīng)過冷作硬化,攪拌車滾道與托輪摩擦面形成光亮的表面。

After the fully automatic small concrete mixer truck is put into use, the ideal state of the roller track and supporting wheel of the mixer truck is to form a bright surface on the friction surface of the roller track and supporting wheel after cold work hardening.

但由于用戶對攪拌車使用操作不規(guī)范,加之制造過程中的缺陷,使得攪拌車滾道與托輪這對運動副在使用過程中達不到理想狀態(tài),表面會出現(xiàn)起皮劃傷、溝槽等現(xiàn)象。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.qirongguanjia.cn進行咨詢吧！

However, due to the user's nonstandard use and operation of the mixer truck and the defects in the manufacturing process, the moving pair of the mixer truck raceway and supporting wheel can not reach the ideal state in the use process, and the surface will appear peeling, scratching, grooving and other phenomena.
