Research on Key Technologies of High Efficiency Solid-Liquid Two-Phase Diaphragm Pump

【Abstract】 The innovative development of high-efficiency solid-liquid two-phase pump and related technology has always been the top priority of the world pump industry. The solid-liquid two-phase diaphragm pump is a kind of wear-resistant, energy-efficient, water-saving and high-pressure. The integrated high-tech pump products are the core equipment in the petrochemical, coal chemical, metallurgical and environmental protection industries. On the basis of analyzing the technical development status and development trend of solid-liquid two-phase diaphragm pumps at home and abroad, the key technologies have been innovated, and the research and innovation focus has been put forward, which will provide certain development for high-efficiency solid-liquid two-phase diaphragm pump development.

I. Introduction

The outstanding advantages of high-efficiency solid-liquid two-phase pump are green environmental protection special pump products. It is a kind of high-tech special application with the continuous development of pump technology and the introduction of high-tech pump products, pump wear, high efficiency, energy saving, water saving and high pressure. However, the water pump products in thermal power plant mortar and coal chemical industry are high-concentration solid-liquid two-phase mediums such as thermal power, coal gasification, coal liquefaction, non-ferrous metallurgy, steel, coal slurry, etc., which have poor fluidity, extremely severe wear, environmental protection and petrochemical industries. Major key equipment. The transportation is extremely difficult and has long plagued the world pump industry.

Second, the status quo at home and abroad

At present, the innovative development of high-efficiency solid-liquid two-phase transfer pumps and related technologies has become the world's pump industry for a long time, and all countries in the world have invested a lot of manpower and material resources. The research and development work of this product, the solid-liquid two-phase diaphragm pump of the famous pump company of foreign countries is a volumetric reciprocating pump. Compared with the traditional reciprocating pump, the most fundamental difference is that one pump is added at the hydraulic end of the pump. Separation has been widely used in electric power, coal chemical, metallurgical and petrochemical industries. The membrane chamber and the diaphragm provided in the diaphragm cavity transport the medium and the driving medium. The GEHO company in the Netherlands has a plurality of electromagnetic controlled diaphragm deformations and should be separated from the oil to eliminate the wear of the solid particles against the plunger (piston). The core technology, the company is a production of solid-liquid two-phase media separation suitable for transporting high-concentration solid-liquid two-phase media. ..... (details below)

LED Point Light Source

LED point light source using imported chip and imported light source, built-in microcomputer chip, arbitrary programming control, multiple synchronous changes.

Mono chromatic of led point light changes can also be synchronized with the color gradient, jump, scan, water and other full-color changes and multiple point light sources to form a lattice screen, changes of various pictures, text and animation effects.

LED point light source also used at building.Bridge, curtain wall, hotel, stage bar, ferris wheel, amusement park, large billboards, square streets and other lighting ideal decorations, but also supplement of linear lighting and floodlight lighting .

The beautiful appearance of point lamp can meet the building body point and surface design requirements, easy control, more convenient installation.
