1. Aggregation: sampling and testing of specific coarse aggregate. Coarse aggregate must be made of gravel or crushed river pebbles, with appropriate gradient direction, excellent material and symmetrical material. Roughly speaking, the index value must comply with relevant specifications, policies and regulations. It is forbidden to manipulate the sand slurry composition and sand slurry composition, immediately detect them, and put the detected defects into the 4-party self feeding concrete mixer.

2.混凝土：混凝土應按照規定抽樣。每一批混凝土鍵入都必須規范的一致性和溫度檢測。假如您對品質有疑問，禁止進到庫房并再次檢測別的指標值。嚴苛嚴禁應用達標的混凝土。禁止在新項目中立即應用沒經加溫的高溫混凝土。

2. Concrete: concrete shall be sampled according to regulations. Each batch of concrete must be tested for compliance with the specifications and temperature. If you have questions about quality, do not enter the warehouse and test other index values again. Strictly prohibit the application of qualified concrete. It is forbidden to immediately apply unheated high-temperature concrete in new projects.

3.礦物質化合物：依據相關規范規格型號的規定開展檢測。試驗室必須解決礦物質化合物品質的轉變。礦物質化合物進到當場后，務必開展用水量，點燃損害和粒度檢測。能夠儲存和紀錄檢測商品以開展基本檢測。較為結果以明確品質起伏并保證新項目品質。

3. Mineral compounds: test according to relevant specifications and models. The laboratory must solve the transformation of mineral compound quality. After mineral compounds enter the site, be sure to carry out water consumption, ignition damage and particle size detection. Be able to store and record tested goods for basic testing. Compare the results to clarify the quality fluctuation and ensure the quality of new projects.

4.減水劑：進到當場時要定期檢查檢測減水劑。查驗混和包裝中的下列新項目。產品名字，型號規格，凈或凈總數，生產商名字，生產制造時間，加工廠序號。保證包裝信息內容合乎產品型號和生產商的證實，而且液體化合物早已從沉淀中墜落而且早已到期。

4. Water reducing agent: regularly check and detect the water reducing agent when entering the site. Check the following new items in the mixed packaging. Product name, model and specification, net or net total number, manufacturer's name, manufacturing time, processing plant serial number. Ensure that the contents of the packaging information comply with the product model and manufacturer's confirmation, and that the liquid compound has long fallen from the sediment and has long expired.

次之，混泥土的砂漿配合比應恰當。

Secondly, the mortar mix proportion of concrete shall be appropriate.

第三，設備齊全完善的4方自送料混凝土攪拌車稱重設備務必精確。

Third, the weighing equipment of the fully equipped 4-party self feeding concrete mixer must be accurate.

4方自送料混凝土攪拌車柴油發動機溫度過高

The temperature of diesel engine of 4m3 self feeding concrete mixer is too high

1.4方自送料混凝土攪拌車在一般路面上使發動機過熱。它應盡早減少速率，將轎車開到樹蔭下面，或調到相對性清涼的地區停住轎車，但不必急切歇火。

1.4 the self feeding concrete mixer truck causes the engine to overheat on the general road. It should reduce the speed as soon as possible, drive the car under the shade of trees, or transfer to a relatively cool area to stop the car, but there is no need to stop the fire urgently.

2.開啟機蓋，讓柴油發動機以待速運作，等候柴油發動機溫度慢慢恢復過來。柴油發動機溫度恢復過來后，關掉柴油發動機。隨后等候一會兒，直至柴油發動機的溫度充足降低，隨后查驗柴油發動機的制冷水流量。

2. Open the engine cover and let the diesel engine run at a standby speed, waiting for the temperature of the diesel engine to recover slowly. When the temperature of the diesel engine recovers, turn off the diesel engine. Then wait for a while until the temperature of the diesel engine decreases sufficiently, and then check the cooling water flow of the diesel engine.

4方自送料混凝土攪拌車危害品質的要素和柴油發動機溫度過高就這樣了，期待對給你協助。

The factors endangering the quality of the 4-party self feeding concrete mixer and the high temperature of the diesel engine are just like this. We look forward to your assistance.
