The 300 plunger pump for aquaculture wastewater treatment usually refers to ceramic plunger pumps with models such as YBH300 or YB-300, mainly used for transporting media such as sludge in aquaculture wastewater. Here is the relevant introduction:

　　Working principle: Taking YBH300 as an example, the pump adopts a hydraulic drive system. The motor drives the oil pump to generate high-pressure oil, which is distributed to two oil cylinders. The two oil cylinders work alternately, and each cylinder drives a ceramic plunger to perform reciprocating motion. When the piston of a hydraulic cylinder moves forward, its corresponding ceramic plunger will suck in the mud; At the same time, the piston of another oil cylinder moves backward, and its corresponding ceramic plunger discharges the mud, achieving continuous transportation of mud through this method.

　　Performance parameters: There are slight differences in the parameters of 300 plunger pumps from different manufacturers. Taking Xianyang Huaxing Pump Industry's products as an example, YBH300J-60 has a rated flow rate of 60 cubic meters per hour, a pressure range of 0-2MPa, a rated pressure of 1.8MPa, a motor power of 45KW, and an external size of 2.11.82.5 meters; YB300G-35 is a high-pressure pump with a rated flow rate of 35 cubic meters per hour, a pressure range of 0-3MPa, a rated pressure of 2.5MPa, and a motor power of 37/45KW.

　　Product Features:

　　Wear resistance: For example, the plunger of YB-300 ceramic plunger pump is made of alumina ceramic fired, with a hardness of HLC8.5 or above, a surface roughness of 0.4um, and no shear motion between the plunger and the conveyed material. It is suitable for conveying aquaculture wastewater containing sand and solid particles.

　　Strong self-priming ability: Adopting a plunger type vacuum pumping method, the self-priming ability is 0-6 meters, and the specific suction distance is determined by the specific gravity of the material.

　　Pressure stability: Some models such as YB-300 have adjustable constant pressure automatic variable function, and the working pressure can be adjusted freely within the range of 0-20 kilograms. The adjusted pressure will not change due to changes in the output flow rate of the pump.

　　Long service life: The wear resistance and corrosion resistance of key components such as ceramic plungers make the pump have a long service life. The YB-300 ceramic plunger pump has a service life of at least 15 years, and the vulnerable parts are valve plates and plunger seals, with a long replacement cycle. Ceramic mud is replaced every 3-6 months, and municipal sludge is replaced every 6-12 months.

　　Application advantages: In the treatment of aquaculture wastewater, the 300 plunger pump can adapt to the high solid content of wastewater, effectively transport media such as sludge with high solid content, and its high pressure can meet the pressure requirements of processes such as sludge pressure filtration, ensuring the smooth progress of the wastewater treatment process.
