DDM series double disc refiner

DDM series double disc refiner is a new refiner specially developed by our company on the basis of digesting and absorbing foreign advanced technology and combining with the production characteristics of China's paper industry. The double-disc grinding machine has two refining zones and a unique balanced feeding device, which is twice as refining capacity as a standard single-disc refiner of the same diameter. The structure is compact, automatic control can be adopted, and the production efficiency is high. It is convenient for operation and maintenance, and is suitable for slurrying and beating of various slurries. According to the process requirements, it can be used in a single unit or in multiple series or in parallel. It is an ideal beating equipment. The DDM double disc refiner has the following advantages: 1. There are two slurry inlets and one slurry outlet. The slurry is fed to the two refining zones by the two pipes through the two pipes, and the slurry is discharged from the slurry pipe after the refining meets the requirements. 2. The refining mechanism contains a floating rotor shaft assembly, a moving seat and two bodies. The rotor shaft assembly rotates between the two bodies, and the moving seat is controlled by two cylinders for axial movement, and the grinding plate is mounted on the rotating disc, the moving seat and a body. 3. The pressure micro-motion is used to adjust the gap of the grinding disc. The control system can adjust the relief valve gap manually or automatically by adjusting the overflow valve or proportional valve according to the slurry quality and output set by the user. 4. Special grinding discs made of special alloy steel and other materials can adapt to the selection of a variety of different slurries and greatly extend the service life. 5. The shaft seal type is sealed with a soft packing and equipped with a sealed water cooling system, so that the pressure and flow rate in the sealed chambers at both ends are kept constant. 6. Both ends of the shaft are supported by double-row spherical roller bearings mounted on the inner taper sleeve, and are lubricated with high-quality lithium grease. 7. The drum-shaped gear coupling with strong bearing performance is used to transmit torque, ensuring low noise, stable transmission, and large axial displacement compensation. 8, according to user needs, PLC programming control (constant power control) can be used to achieve automatic control and monitoring of the beating process.

KH type chemical process pump

KH type chemical process pump is a new type of chemical pump developed by our company on the basis of digestion and absorption of foreign technology. It adopts full-open impeller design. The structure adopted by the pump determines that the concentration of the conveying medium is higher than that of the closed type and semi-open type pump, and the medium passing ability is strong; the exhaust performance is good, especially suitable for alkali recovery or the like; the axial force is small, The shaft and the bearing have small damage and low energy consumption, so the operation is stable, the noise is low, and the maintenance is convenient. The pump adopts a single-stage single-suction cantilever structure, which can disassemble or install the impeller, the rear wear plate, the shaft seal component and the bearing frame without disassembling the pump inlet and outlet pipes.

Applicable to the paper industry (such as alkali recovery section), chemical, pharmaceutical, petroleum, environmental chemical, food and other industries. The main advantages of KH chemical process pump: 1. The impeller is a three-blade (or six-blade), fully open structure (so the axial force is small), which can transport high and low temperature, corrosive, medium containing certain particles, viscosity and air content, and has high efficiency. The impeller has a stable low pressure at the shaft seal, effectively reducing the pressure at the shaft seal. The structure of the impeller is easy to maintain and is not easy to block, and is cast by lost wax, and is G6.3 grade dynamic balance check. 2. Because the impeller is a fully open structure, the current is small at startup, the shearing force on the shaft is small at startup, and the overall load is reduced during operation. The axial force during operation is small, so the service life of mechanical seals and bearings is greatly extended. 3.
