Problems solved by technology
Obviously, due to the use of a diesel engine as a power source, the overall emission and energy consumption of the equipment are relatively high; in terms of control, the power matching characteristics between the pumping system and the diesel engine need to be considered. If the matching is not good, excess energy will be wasted ; In addition, the high-speed operation of the diesel engine and the pressure shock during the reversing of the hydraulic system will cause large noise; and the hydraulic pressure output by the hydraulic pump needs to pass through the hydraulic pipeline and hydraulic valve block before reaching the hydraulic cylinder, so there is a certain amount of energy loss, if the hydraulic oil leaks, it is easy to pollute the environment

The invention belongs to the field of engineering machinery, and discloses a material pumping system and pumping equipment. The material pumping system (100) comprises a hopper (1); a pumping main body mechanism which comprises a pumping cylinder (2) connected with the hopper (1) and a piston (3) arranged in the pumping cylinder (2); and an electric control mechanism which is used for controlling the piston (3) to reciprocate in the pumping cylinder (2) so that the pumping main body mechanism can suck materials in the hopper (1) into the pumping cylinder (2) and then pump the materials outwards. Therefore, the system does not have any hydraulic flow and impact in the operation process, has no oil leakage risk, is high in reliability, simplifies the control flow and mode under the mode of directly controlling the piston in an electric mode, and is convenient to maintain quickly, and compared with a traditional diesel power driving mode, the system greatly improves the energy utilization rate, reduces noise, realizes zero emission, and avoids environmental pollution.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a material pumping system and pumping equipment. Background technique [0002] Pumping equipment is a kind of large-scale construction machinery that is widely used. Since its birth, problems such as high fuel consumption, low energy utilization, and poor emissions have always existed. The main reason is that most pumping equipment uses diesel engines or The motor is used as the power source and hydraulic actuators are used. To reduce equipment energy consumption and emissions, it is necessary to optimize the power matching between the pumping system and the power source or improve the pumping system itself, but this also increases the pumping equipment. The complexity of the control system. [0003] In the pumping equipment that uses a diesel engine as a power source, the equipment uses the diesel engine to drive the hydraulic pump to output oil to provide energy,...
