　　working principle

　　Ceramic plunger pumps rely on the reciprocating motion of ceramic plungers in the cylinder body to achieve suction and discharge. When the plunger moves upward, negative pressure is formed inside the pump cylinder, the suction valve opens, and the liquid is sucked into the pump cylinder; When the plunger moves downwards, the pressure inside the pump cylinder increases, the suction valve closes, the discharge valve opens, and the liquid is forcibly discharged. Through the continuous reciprocating motion of the plunger, continuous liquid delivery is achieved.

　　structural characteristics

　　Ceramic plunger: Made of high-performance ceramic materials such as alumina ceramics, it has the advantages of high hardness (up to HRC8.5 or above), strong wear resistance, good corrosion resistance, and high chemical stability. It can maintain good working performance under harsh working conditions such as high pressure and high wear.

　　Sealing device: High performance rubber or polytetrafluoroethylene materials are usually used to ensure the sealing of the pump under high pressure and prevent liquid leakage.

　　Hydraulic end: including pump cylinder, suction valve, discharge valve and other components, the design focuses on optimizing the flow channel, reducing liquid flow resistance, and improving pump efficiency and stability.

　　Performance advantages:

　　Wear resistance: The ceramic plunger has no shear motion with the conveyed material, making it suitable for conveying materials containing sand and solid particles. Its wear resistance can minimize the wear of the pump when conveying highly abrasive media, extending the maintenance cycle of the equipment.

　　Strong self-priming ability: Adopting a plunger type vacuum pumping method, the self-priming ability can reach 4-8 meters, and the specific suction range is determined by the specific gravity of the material.

　　Flexible pressure regulation: The working pressure can be adjusted within a certain range (such as 0-20 kilograms or higher), and can automatically switch from low-pressure large displacement slurry delivery to high-pressure small displacement slurry delivery according to the working conditions of the filter press. When reaching a constant pressure state, the pressure can be kept constant.

　　Efficient and energy-saving: The flow rate can be automatically adjusted according to the set pressure. The variable displacement pump has a constant flow rate in the low pressure range. After the pressure rises to the set value, the flow rate decreases with the increase of pressure, and the motor power decreases accordingly. Compared with the fixed displacement pump, it can significantly save energy.

　　Strong corrosion resistance: Ceramic materials have stable chemical properties and can effectively resist the erosion of corrosive materials containing acidic and alkaline substances, ensuring the long-term stable operation of the pump body and internal key components.

　　Application fields:

　　Mainly used in the metallurgical industry, such as various non-ferrous metal smelting, beneficiation, and tailings treatment; Concentrated sludge treatment, such as sedimentation sludge and concentrated sludge; Chemical and other industries, such as dyeing pigments, titanium, quartz sand, carbon black, coal water slurry, kaolin, magnetic materials, flue gas desulfurization and dust removal, electronic pulp, ceramic clay, bentonite, various glazes, salt mud, saponin, food and food residue, etc., are used for pressure filtration and transportation.

　　Common models

　　Taking the YB series of Xianyang Huaxing Pump Industry as an example, there are models such as YB300-40, which have a rated flow rate of 40 cubic meters per hour, a pressure range of 0-2.0MPa, a rated pressure of 1.8MPa, and a motor power of 30KW.
