Problems solved by technology

In the past, "excavating soil from the mountain" was often adopted. Construction equipment was many, the cost was high, the construction period was long, and the environmental protection was damaged.
At present, traditional mud pumps are used in China to "take soil from the inland sea". The material transported to the working surface contains up to 90% water, and only less than 10% of the silt can be used
Low efficiency and easy to cause subsidence of working face

Embodiment Construction

[0015] Sludge pump technology, in terms of its structure and performance, is mainly divided into three parts: pumping system, hydraulic system and electrical system.

[0016] The pumping system of the present invention adopts dual power to drive the hydraulic oil pump group separately, so that the pumping work is stronger and the system is more reliable. The electrical system adopts PLC programmable control system, which prolongs the trouble-free working time. The hydraulic system is equipped with double safety devices of main oil pump pressure cut-off and safety valve. Effectively improve the reliability of the whole machine. The present invention takes the MPS330 sludge pump as an example.

[0017] According to accompanying drawings 1, 2, 3, 4, the power unit of the sludge pump of the present invention is relatively independent from the pumping system, and the two parts are connected by hydraulic pipelines. The power device of the sludge pump is composed of the chassis 1,...

Abstract

The invention relates to a silt pump and relative operation method, which comprises a pumping system, an electric system and a hydraulic system. It is characterized in that: the pumping system uses two motors to drive the hydraulic pump, and via the bottom bracket, the front bank, the diesel oil bank, the side gate, the hydraulic oil bank and the diesel oil engine to form the power device of pumping system with mechanical connection; the power device and the pumping part are independent which are connected via hydraulic tubes; said hydraulic system uses two main pumps while each one can be used lonely; said electric system uses PLC programmable control system. The invention has high intelligent degrees of dual-power system and dual-main axle pumping system, with energy-saving, high efficiency and wider application.

Description

technical field [0001] The invention relates to a mud pump, and in particular discloses a mud pump and its operating method, which are used for pumping seabed mud, ore mud and the like with poor fluidity, high viscosity, low slump, and poor material absorption. Background technique [0002] In recent years, the economy of coastal cities has achieved considerable development, and the demand for land resources is also increasing. Adopting "reclaiming land from the sea" has become one of the methods for cities to increase available land resources. In the past, "excavating soil from mountains" was often used for construction equipment, high cost, long construction period, and damage to environmental protection. At present, traditional mud pumps are used in China to "take soil from the inland sea" in a single operation. The materials transported to the working surface contain up to 90% water, and only less than 10% of the silt can be used. The efficiency is low and it is easy to...
