Stepless adjustment of pump truck delivery capacity of small-scale concrete mixer: stepless adjustment of pumping speed is realized, and discharge gate of hopper is installed? Small pump truck price can be in accordance with the specific situation of construction, 33m series concrete mixing machine! It can change the pumping displacement and satisfy different working conditions.

保養(yǎng)辦法：1，小型混凝土攪拌一體機保養(yǎng)辦法應遵照產品闡明書中對應地要求和辦法，對運用前，后泵車相關項目開展查看。直接吊水法1)查看切開環(huán)和眼睛板之間的摩擦損壞狀況，這是決議直接吊水法清洗勝敗的要害。若切開環(huán)和眼睛板摩擦損壞不嚴峻，切開環(huán)和眼睛板時間周期＜0.1mm，且它們之間無超越1mm的溝槽劃痕，可用直接吊水法。

Maintenance methods: 1. The maintenance method of small-scale concrete mixer should follow the corresponding requirements and methods in the product specification, and check the relevant items of pump truck before and after use. Direct hanging water method 1) check the friction damage condition between the incision ring and the eye plate, which is the key to the success or failure of the direct hanging water method. If the friction damage between the incision ring and the eye plate is not severe, and the time period of the incision ring and eye plate is less than 0.1 mm, and there is no groove scratch beyond 1 mm between them, the direct water lifting method can be used.

           

2)在泵送完砼后再泵送0。15～0。25m3水灰比為1∶1。5或1∶2的砂漿，然后在分配閥中加滿水，發(fā)動泵送，將砼泵送到澆注位置，直運送管輸出端流出清水停止。倘若管道較短，清洗作用較好，則清洗過程到此結束。

2) After pumping concrete, pump 0. 15～0。 The water cement ratio of 25m3 is 1 ∶ 1. 5 or 1:2 mortar, and then fill the distribution valve with water, start pumping, and pump the concrete to the pouring position until clear water flows out of the delivery pipe. If the pipeline is short and the cleaning effect is good, the cleaning process is over.

3)封閉上料斗卸料門，向料斗中加水，當水加砼缸直徑2/3高度時，將柱狀體頭部朝分配閥方向裝入砼缸，用1根長約1m，直徑約30mm的木制橇棒將柱狀體抵住，繼續(xù)加水拌和軸中心線。撤出撬棒，迅速發(fā)動泵送，繼續(xù)加水，直柱狀體從運送管輸出端泵出。加活塞法的長處是管道清洗較潔凈，水源的流速能夠偏低，能夠暫停，一起環(huán)比減少拆出料口和彎管的費事。

3) Close the discharge door of the upper hopper and add water to the hopper. When the water is added to the height of 2 / 3 of the diameter of the concrete cylinder, the head of the column is loaded into the concrete cylinder in the direction of the distribution valve, and the cylinder is butted with a wooden sled bar about 1m long and 30mm in diameter, and water is added to the center line of the mixing shaft. Remove the crowbar, start pumping quickly, and continue to add water until the cylinder is pumped out of the delivery tube. The advantages of the piston method are that the pipeline cleaning is relatively clean, the water flow rate can be low, can be suspended, and the cost of removing the outlet and elbow is reduced.

4)混凝土攪拌一體機價格封閉在低壓泵送狀態(tài)下的泵送方量，混凝土攪拌一體機膠管價格而實踐施工中不足以具備上文講的的條件。它取決于如下要素。（1）泵送系統恒效率點：現如今國內外企業(yè)制作的混凝土泵，其泵送安排均選用恒動力等級系統。

4) The price of the concrete mixing machine is closed in the pumping volume under the low-pressure pumping state, and the rubber tube price of the concrete mixing machine is not enough to meet the conditions mentioned above in the practical construction. It depends on the following elements. (1) Constant efficiency point of pumping system: at present, the pumping arrangement of concrete pump made by domestic and foreign enterprises adopts constant power grade system.

當泵送壓力高時泵送方量低，泵送壓力低時，泵送方量增加到動力等級安穩(wěn)，有利于動力和主油泵的合理匹配，從泵送性能曲線可看出，基本恒功率等級曲線MPa左右。

When the pumping pressure is high, the pumping volume is low; when the pumping pressure is low, the pumping volume increases to the power level, which is conducive to the reasonable matching of power and main oil pump. From the pumping performance curve, it can be seen that the basic constant power rating curve is about MPa.
