Rubber Plastic Insulation Material Rubber insulation material is an elastic closed cell foaming material, which has the advantages of low thermal conductivity, fire and flame resistance, humidity resistance, vibration and noise reduction, environmental protection and health, long service life, elegant appearance and convenient installation. It is widely used in central air conditioning, construction, chemical industry, medicine, textile, metallurgy, shipping, automobile, electrical appliances and other related cold and hot medium pipes or containers, can achieve the effect of reducing cold loss and heat loss. In addition, the construction is simple, the appearance is neat and beautiful, and the product does not contain fiber dust, will not breed mold and other harmful substances, so it is a new generation of high-quality thermal insulation material.

ZJL series of submerged slurry pump ZJL type for single-stage, single suction, vertical centrifugal slurry pump, the series of pumps using advanced international solid-liquid two-phase flow theory, according to the principle of minimum loss design. The geometry of the overcurrent component conforms to the flow state of the medium and reduces the hydraulic losses of local and alongside processes such as eddy current and impact so as to reduce the wear of the overcurrent component and improve the hydraulic efficiency and reduce the operation noise and vibration; Over-current components using high-hardness alloy cast iron, the material has high abrasion resistance, corrosion resistance, impact resistance, thereby increasing its life. ZJL slurry pump generally immersed in the pool or pit work, do not need any shaft seal and seal water. Long axis series of submerged pump, can be applied to deep level conditions. The pump is suitable for mining, metallurgy, electric power, coal, chemical industry, building materials and other industries, transportation of abrasive and corrosive slurry containing solid particles, the maximum weight concentration of solid-liquid mixture: 45% mortar, pulp 60%. Model: 40ZJL-B25 (J) 40: Pump outlet diameter (mm) Z: Impurity pump J: Slurry L: Vertical submerged pump 25: Impeller diameter (cm) B: Number of impeller blades 4 A 5 (omitted), B = 4, C = 3, F = 6, G = 7, and H = 8. J: reamer structure: The series of pumps using internationally advanced solid-liquid two-phase flow theory, according to the principle of optimization design, the geometry of the flow components in line with the flow of the medium state, reducing the eddy current and impact and other local and along the water Loss, thus reducing the flow of parts wear and improve hydraulic efficiency, reducing running noise and vibration; Material: The pump flow components using high-hardness alloy casting, the material has high abrasion resistance, corrosion resistance, resistance Impact performance, thereby increasing its life expectancy, in addition, the series pump power step-down to ensure that the slurry is not easy to leak. Use: Mainly used in concentrates and tailings processing plant, power plant in addition to ash, coal preparation plant coal and heavy medium coal seiners, sand handling and other coastal sand handling. The maximum weight concentration that it can process the slurry is: mortar 45%, pulp 60%.
