Abstract

The invention discloses a hydraulic thrust sludge high-pressure plunger pump. The hydraulic thrust sludge high-pressure plunger pump comprises a plurality of plunger assemblies and an electric control system used for controlling the multiple plunger assemblies to act independently or act jointly. Each plunger assembly comprises a single pump hydraulic end, a power pump set and an oil tank assembly which are connected through a hydraulic pipeline, wherein the single pump hydraulic end comprises a feeding and discharging unit, a pump body assembly, a main plunger, a main plunger thrust oil cylinder, a secondary plunger thrust oil cylinder and a main control valve set; the sludge feeding and discharging unit comprises a feeding inlet, a sludge inlet assembly, a feeding valve assembly, a discharging outlet and a one-way valve assembly; the secondary plunger thrust oil cylinder is connected with the sludge inlet assembly through the feeding valve assembly; the main plunger thrust oil cylinder is connected with the pump body assembly through the main plunger; the pump body assembly communicates with the feeding inlet through the sludge inlet assembly and communicates with the discharging outlet through the one-way valve assembly; the main control valve set comprises a proportional valve and an electromagnetic reversing valve arranged on an oil inlet and outlet passage of the main plunger thrust oil cylinder and the secondary plunger thrust oil cylinder; and the oil tank assembly is connected with the power pump set.

Description

technical field [0001] The invention relates to the field of hydraulic technology, and more specifically relates to a hydraulic thrust sludge high-pressure plunger pump used as a key power source in a production line for municipal garbage sludge treatment (sludge low-temperature carbonization treatment process). Background technique [0002] Our country's constitution has provisions to protect the environment, and has promulgated a series of laws, regulations, regulations and standards such as the Environmental Protection Law to protect the environment and ecological balance. [0003] The municipal solid waste sludge treatment project is one of the important infrastructure projects for protecting the environment and ecological balance. If it is not handled properly, it will easily cause serious pollution to the environment, especially the air pollution, which will cause serious harm to people's lives and the ecological environment. Therefore, the awareness of environmental p...
