Novel high-flow emulsion pump station

Abstract

The invention discloses a novel high-flow emulsion pump station. The invention provides a herringbone tooth transmission structure externally hung on two helical gear sets. The advantage in eliminating axial force is reserved, and the defects that the machining precision requirement is high, the assembly process is complex, and follow-up overhaul and maintenance are inconvenient are overcome. As a crankshaft multi-point supporting technology of a non-integral split type transmission box body is adopted, the problem that a two-point supporting type crankshaft and a transmission box body are large and heavy is solved, and the problem that an integral split type transmission box body is high in machining, manufacturing and assembling process requirements and inconvenient in field maintenance and later maintenance is solved. An independent external circulation lubricating system is provided, a transmission box and an oil tank are separated, closed-loop management and control of cleanliness and quality of lubricating oil are achieved, and a premise is provided for advanced starting of a lubricating system before a pump station is started and lagged shutdown of the lubricating system after the pump station is stopped. The pump station integrally adopts a bilaterally symmetrical structure and can meet the arrangement requirements of left and right working faces of a coal mine.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering hydraulics, in particular to a novel large-flow emulsion pumping station. Background technique [0002] The emulsion pump station is the necessary equipment for the comprehensive mechanized coal mining face of the coal mine. It is the power source of the hydraulic support of the working face. The movement of components such as plugs converts mechanical energy into hydraulic energy. [0003] Emulsion pumping stations originated in the United Kingdom, Germany and other western countries in the 1950s. my country began to import and apply them in the 1970s, and gradually realized localization. Traditional domestic pumping stations are limited by historical production and design levels, as well as the characteristics of coal mine conditions and management levels. The design concept is based on anti-pollution design, adaptability to working conditions, and maintainability. not tall. Ba...

AI Technical Summary

Problems solved by technology

However, limited by the domestic basic industry, industry manufacturing level and technological level, it is found that there are many problems in the domestic replication of the structural form of these imported pumping stations.

First, the manufacturing cost is high, and the actual effect of the pumping station is still far behind that of foreign countries. Second, the domestic coal mining technology, coal mining intensity and mode have far exceeded the level of foreign developed countries in the past ten years, and imported pumping stations are also There are many deficiencies, so the imported foreign technology and equipment can not fully adapt to the current development of domestic coal mining requirements
