The flow parts of the hydraulic mud pump are made of high chromium wear-resistant alloy materials. After a large number of tests and industrial field operation tests, the pump is wear-resistant, energy-saving, reliable in operation, high lift, and submersible (can be pumped to a depth of 60 meters) , Large flow (up to 1000 cubic meters per hour for a single pump), wide application range, long conveying distance, etc. The pumped solid-liquid mixed concentration can reach 60, which is suitable for pumping various mud, slag slurry, silt, ore, industrial and mining enterprises to transport slag, tailing slurry, tailings ore, slurry, power fly ash transportation and other highly abrasive media . Main features of hydraulic slurry pump 1. There is a stirring impeller at the bottom of the pump, which can prevent large solid materials from blocking the pump, so that the solid and liquid are fully mixed, which is easier to handle. 2. This pump can handle solid materials with a particle size of 50mm, and the solid-liquid extraction concentration can reach more than 70; Note: Due to different working conditions, the output of the pump may also vary with the influence of factors such as the processed medium, on-site operation, and transportation distance. 3. This device is mainly installed on the excavator. The power is provided by the hydraulic station of the excavator, which can realize free transition, and the power source is a diesel engine, which can solve the problem of power inconvenience during construction in remote areas. 4. The flow parts are made of hard chromium alloy, which has a long service life. The hydraulic drive of the dredging pump of the excavator has the following advantages: 1) Light weight per unit power, that is, under the condition of the same output power, it is small in size, light in weight, small inertia, compact in structure, and good in dynamic performance. 2) The hydraulic transmission device works smoothly, responds quickly, has little impact, and can quickly start, brake and change directions frequently. It is convenient to realize stepless speed regulation, and the speed regulation range is large. 3) Hydraulic transmission is easy to obtain large force and torque, which can make the transmission structure simple and low failure rate. 4) The control and adjustment of the hydraulic transmission device are relatively simple. It is more convenient, labor-saving, and easy to realize automation. 5) The hydraulic system is easy to achieve overload protection. At the same time, because the oil is used as the transmission medium, the relative moving surfaces can be lubricated by themselves, so the original parts have a long service life. Excavator dredging pump-dredging pump driven by excavator with hydraulic reamer 6) Since the hydraulic components have been standardized and generalized, the design, manufacture and use of the hydraulic system are more convenient. The arrangement of hydraulic components also has greater mobility. Structural characteristics of excavator slurry pump 1.

Mechanical seal leakage and solutions (1)-leakage of media

Mechanical seal leakage is sometimes related to the conveying medium of the corrosion-resistant pump. When the medium is strong in acidity or alkalinity or contains solid particles, it can also cause leakage. (1) After most of the mechanical seals of submersible sewage pumps are disassembled, the auxiliary seals of the stationary ring and the moving ring are inelastic, and some have rotted, causing a large amount of leakage of the mechanical seal and even the phenomenon of shaft grinding. Due to the corrosive effect of high temperature, weak acid and weak alkali in the sewage on the static ring and the auxiliary rubber seal of the moving ring, the mechanical leakage is too large. The material of the moving and static ring rubber sealing ring is nitrile-40, which is not resistant to high temperature. It is not resistant to acid and alkali, and it is easy to corrode when the sewage is acid and alkali. Countermeasures: For corrosive media, rubber parts should be fluorine rubber resistant to high temperature, weak acid and weak alkali. (2) Mechanical seal leakage caused by solid particles and impurities If solid particles enter the end face of the seal, it will scratch or accelerate the wear of the end face. The accumulation of scale and oil on the shaft (sleeve) surface exceeds the wear rate of the friction pair, resulting in The moving ring cannot compensate for the wear displacement, and the operating life of the hard-to-hard friction pair is longer than that of the hard-to-graphite friction pair, because solid particles will be embedded in the sealing surface of the graphite sealing ring. Countermeasures: The mechanical seal of tungsten carbide to tungsten carbide friction pair should be selected in the position where solid particles are easy to enter. The corrosion-resistant pump manufacturer Keyikai focuses on the research and development and production of intelligent corrosion-resistant pumps, allowing the pump to work like a human, with zero cost maintenance. The company has many on-site installation engineers with 20 years of industry experience, free of charge for customers to answer on-site installation and maintenance problems.

Micro lubrication better than traditional lubrication for metal cutting

No matter what kind of metal cutting, tool performance, cutting force, and lubrication effect are all factors that affect cutting efficiency and tool durability. The role of lubrication in cutting is between "tool-workpiece" and "tool-chip" Provide a good lubricating oil film, so that it can inhibit temperature rise, reduce tool wear, and prevent adhesion. Because the traditional cutting fluid and cutting oil pouring lubrication can not effectively generate oil film on the friction surface. Therefore, the lubrication effect cannot be fully exerted, and the pouring cooling is easy to form a thermal shock to the tool, which leads to a decrease in tool durability. The key to micro-lubrication is that ultra-fine oil mist particles can easily penetrate and adhere to the cutting friction zone to form an oil film. The international mainstream products of micro-lubrication technology are all micron-sized oil mist particles produced by an oil mist generator and compressed air to form a mixed flow that is sprayed to the cutting friction area at a high speed to form a lubricating oil film. Multiphase flow micro-lubrication: application direction tapping, sawing, guide rails, screw rods, wire ropes and other fields, as well as traditional equipment turning, milling, and other transformation projects with lower investment. The use of oil-gas two-phase flow or oil-gas-water three-phase flow is a form in which compressed air tears the oil droplets into oil mist at the outlet end of the external nozzle. The oil mist particles formed in this way are larger, the permeability is poor, and Can not fully form a reliable lubricating oil film in the cutting friction zone. The addition of water solves the cooling of chips, workpieces, and tool body after friction deformation, and the problem of cutting heat during friction cannot be effectively suppressed. In the case of multiphase flow, the lubrication status has not been effectively improved, and the harmful thermal shock to the tool life continues to exist, which is uncertain in terms of production. At present, the mainstream cutting fluid alternative is MQL micro-lubrication technology (micron-level oil mist particles are generated by an oil mist generator and compressed air to form a mixed flow and sprayed to the cutting friction area at a high speed to form a lubricating oil film). The production lines that have been put into production use this Technology.
