Hydraulic Concrete Pump - Hydraulic Pump for Concrete Mixer
Hydraulic Concrete Pump Hydraulic Pump for Recently hydraulic concrete pump comes to be one of the hot concrete pumps in the market. And its hydraulic system is considered as the heart of concrete pump, which is closely related to pumping efficiency. Though
The cleaning of hydraulic system of hydraulic concrete pump is really important. The cleanliness of the hydraulic system for hydraulic concrete pumps is related to the life of the system. If we compare the main pump to the heart, then the hose, steel pipe, valve block, fuel tank can be considered as blood vessels undoubtedly.
Fitting the flexible-hose concrete pump with a hydraulic drive allows both making the range of its operating modes much broader and enhancing its reliability. Numerically simulated models of the building mixes feeding processes were developed to design a hydraulic drive to fit the general-service flexible-hose concrete pump and to calculate its basic parameters.
2. Main oil pump: truck-mounted concrete pump uses Rexroth / Japan Kawasaki series. The variable plunger pump is used to ensure the smooth operation and reliability of the system. Moreover, it has overpressure overflow function, which can effectively protect 3.

• The stationary concrete pump adopts open-type full-hydraulic-reversion system and hydraulic oil is kept clean. It features low oil temperature and small shock during reversing; • Concrete pistons can retract automatically for easier inspection and
1/7/2016 · For improving the reliability of Concrete pump, fault diagnosis is proposed based on the main oil hydraulic pumping system T-S fuzzy fault tree method. The proposed method used fuzzy numbers to describe the probability of failure of hydraulic components and systems to address the failure probability of uncertainty; described by T-S fuzzy door
Reliability Research of Concrete Pump Main Oil Hydraulic System Based on T-S Fuzzy Fault Tree Qing Zhao1,Lijun Li1, Hongbin Tang 2 1School of Mechanical and Electronic, Central south University of Forestry and Technology, Changsha, 410004, Hunan2
In the failure of the concrete pump truck, the failure rate of the hydraulic system was about 70 % and the piston pumps accounted for about 40 %. Therefore, it is of great significance to carry out the research on condition monitoring and fault diagnosis of piston pump.
The cleanliness of the hydraulic system for hydraulic concrete pumps is related to the life of the system. If we compare the main pump to the heart, then the hose, steel pipe, valve block, fuel tank can be considered as blood vessels undoubtedly. Thus our company always ensures the cleanliness of the hydraulic …
