YB400 sludge plunger pump is a commonly used equipment in sludge treatment and other fields. The following is a related introduction:

　　Working principle: YB400 sludge plunger pump is usually a hydraulic driven double cylinder double acting displacement pump. The motor drives the gear oil pump, converting 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, achieving slurry suction and discharge, and completing the transportation of sludge and other fluids.

　　Performance parameters: Taking Xianyang Huaxing Pump Industry's products as an example, the YBH400-120 energy-saving mud pump has a flow rate of 120 cubic meters per hour, a pressure range of 0-1.5 MPa, a stroke of 350 mm, and a motor power of 30 kW. The YBH400-180 filter press sludge pump has a flow rate of 180 cubic meters per hour, a rated pressure of 0-1.5 MPa, and is equipped with a motor of 45 kW.

　　Product Features:

　　Wear resistant and corrosion-resistant: Usually using alpha alumina as the plunger, it has extremely high wear resistance and corrosion resistance, which can resist the erosion of corrosive substances in sludge. It is suitable for transporting sludge containing sand and solid particles, reducing wear and extending the service life of the pump.

　　Pressure stability: It can automatically control the output flow rate and ensure that the set pressure remains unchanged. When the pressure rises to the set value, the pump's flow rate can automatically change the operating speed and maintain the set pressure between zero and maximum flow according to actual needs, with small pressure fluctuations.

　　Strong self-priming ability: Adopting a plunger vacuum pumping method, the self-priming ability can reach 5-9 meters, which can meet the feeding needs under different working conditions.

　　Energy saving and efficient: Belonging to variable displacement pumps, the flow rate remains constant 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 quantitative pumps, the energy-saving effect is significant.

　　Easy to operate: Pressure regulation only requires tightening or loosening the pressure regulating valve. After adjusting the pressure, it is locked and usually does not need to be adjusted again. Additionally, the replacement cycle of vulnerable parts is long and the maintenance cost is low.

　　Application field: It is widely used in chemical industry, metallurgy, environmental protection, coal and other industries, and can be used for ceramic slurry spray drying, coal water slurry high-pressure spray combustion, long-distance transportation of various suspended liquids, slurries, and sand containing liquids, especially for filter press feeding, to help achieve solid-liquid separation.
