Hydraulic ceramic plunger pump is a commonly used pump equipment in the field of sewage treatment. The following is a detailed introduction about it:

　　Working principle: Hydraulic ceramic plunger pumps are usually hydraulic driven dual cylinder double acting displacement pumps. The motor drives the gear oil pump, which converts low-pressure oil into high-pressure oil. The high-pressure oil alternately enters two hydraulic cylinders through the reversing valve, driving the hydraulic cylinder piston and then driving the ceramic plunger to perform reciprocating motion. During the reciprocating motion of the plunger, the slurry is sucked and discharged through the inlet and outlet valves of the working cylinder, thereby achieving the transportation of fluids such as sewage.

　　Stable pressure: With high working pressure and minimal pressure fluctuations, it can provide stable pressure support for specific processes in wastewater treatment, such as deep filtration and sludge pressure filtration, ensuring consistent treatment effectiveness.

　　Flexible flow regulation: Some models of hydraulic ceramic plunger pumps have the function of adjustable flow, such as the variable displacement pump in the YB series, which can automatically adjust the flow rate. The flow rate remains constant in the low pressure range. When the pressure rises to a certain set value, the flow rate decreases with the increase of pressure, and the motor power decreases accordingly, which can better adapt to the flow requirements of different stages in the sewage treatment process.

　　Strong self-priming ability: Adopting a plunger vacuum pumping method, the self-priming ability can usually reach 4-8 meters, and the suction range may vary due to the specific gravity of the material. It has advantages in wastewater extraction from some open or low-level water tanks in sewage treatment plants, reducing the need for additional suction equipment.

　　Good wear resistance: The plunger is made of alumina ceramic fired with a hardness of HLC8.5 or above, a surface roughness of 0.4um, and there is no shear motion between the plunger and the conveyed material. It has good wear resistance for some solid particles that may exist in sewage, which can effectively reduce the wear and replacement frequency of the plunger and lower maintenance costs.

　　Energy saving and efficient: Under the same flow rate and head conditions, the motor power of the hydraulic ceramic plunger pump is relatively small, with high energy utilization efficiency. It can more effectively convert electrical energy into hydraulic energy, which is then converted into mechanical energy for conveying slurry. The energy loss is small, which can effectively reduce energy consumption.

　　Application in sewage treatment: Hydraulic ceramic plunger pumps are widely used in sewage treatment, such as in plate and frame filter presses for sludge dewatering, which can stably transport the sludge under pressure and ensure efficient sludge dewatering work. It can also adapt to different types of sewage slurry, whether it contains small particles or has a certain degree of corrosiveness, it can handle them with ease.
