High-speed railway girder concrete pump

Qingdao CO-NELE Heavy Industry Co., Ltd. is a research, production, sales and after-sales service in one of the professional development of large-scale construction machinery business. To meet the demands of high performance concrete pumping, the company's high-performance concrete pump suction performance and efficiency in-depth research, developed a high-speed rail system for special concrete pump beam. The pump has the dual power, dual systems, high pressure, large displacement, no blockage, to ensure conditions and so on. Relative to the normal high-power concrete pump, its pumping effect, transport emissions increased substantially.
Features:
(1) dual motor, dual-pump system, strong power.
Iron beam used for high-grade high viscosity, and poor can pump concrete features. Dedicated high-speed rail system, 2 sets of beam pump 90kW (or 110kW) motor, 2 190 (260)-type oil pump Rexroth main driving force for the system to ensure the long distance of 400 meters above conditions on the emissions of 50 high-performance concrete delivery cubic meters / hour.
(2) reduce the impact of hazards on the construction grid.
As the motor starts the motor itself, the instantaneous current intensity of 3 times rated current, therefore, 132 kW power over motor current at startup will cause great impact on power grid construction hazards, and even can cause tripping, power outages burn equipment and other major incidents. The pair of electrical pump in the boot, two motors were started, to avoid transient high-current power strong impact on the construction hazards, protect construction facilities, to protect the smooth construction. Moreover, the use of large displacement high pressure pump, the double pump confluence, their efficacy or whether the main pump motor power emissions are much higher than ordinary single-power pump.
Pump reliability are increased.
(3) energy efficiency.
Dual power pump in the completion of high-grade, high strength, durability, the Concrete Beam pumping task, still used for general concrete construction. At this point can only only use a single motor and the main pump can work to achieve common pump effect. Another motor and the main pump in standby mode can be enabled at any time. Great to ensure the construction of continuity and good energy efficiency.
(4) scientific, reasonable and reliable system design.
Can guarantee the long-range, under high pressure pumping system to achieve large displacement beam-specific strength, viscosity over a large C50 grade concrete, is dedicated Beam Pump and the difference between ordinary pump. As a result of beam-specific pump to increase fuel tank design, improved hydraulic valve, enhanced mixing system, a unique hopper design, has good suction resistance. A small diameter, large diameter pipelines, pumping sealing and so good to solve the problem of high strength concrete pumping the key.
