JYPJ- Series Cutting Type Sewage Lifters

Equipment Composition

The JSPJ series cutting type sewage elevator mainly consists of a closed stainless steel water collection tank, cutting pump, pipeline valve components, liquid level controller, base and its accessories.

Water collection tank: A closed stainless steel water collection tank is used to collect and store sewage discharged from sanitary facilities.

① The water collection tank is made of impact resistant and corrosion-resistant 304 stainless steel plate, which is welded using single-sided welding and double-sided forming argon arc welding technology. The inner surface of the water collection tank is treated with anti-oxidation treatment.

② The wall thickness of the water collection tank and its connecting components can withstand an internal pressure of not less than 0.10MPa, while meeting the external load requirements (100kg) for maintenance personnel to carry out maintenance with tools.

③ The water collection tank is equipped with a closed inlet (the inlet position can be set according to the actual location of the user's site), outlet, exhaust port (not less than DN50), discharge port, maintenance port and other reserved interfaces.

④ The water collection tank is completely airtight and water tight, with no odor leakage.

⑤ The external dimensions of a single standard water collection tank are 1000X700X1000 and 1000X1000X1000 (different specifications can be made according to the user's usage location), and multiple (no more than 3) water tanks can be connected in parallel. The cutting sewage pump is equipped with an alloy cutting blade at the inlet of the water pump, which can cut and crush the cloth strips, sanitary products and other pollutants contained in the sewage before discharging.

① Impeller: Semi open structure vortex blade, made of HT250 cast iron integral resin sand casting.

② Cutting knife: made of alloy or stainless steel material, installed at the inlet of the water pump, can crush various flexible garbage and prevent water pump blockage.

③ Motor: YX3 series motor, insulated with F-class 155 ℃, protection level IP55, cooling method Ic411, can start up to 20 times per hour.
④ Shaft: Made of 2Gr13 material, with a cantilever short shaft design, coaxial with the motor, which can eliminate winding, extend the life of the machine seal and bearings, and reduce vibration and noise. The dynamic balance meets the requirement of G6.3 level.
⑤ Bearings: Standard sealed spherical rolling bearings that can withstand axial and radial loads under any operating conditions. The bearings are lubricated with grease, with a working temperature of ≤ 75 ℃ and a lifespan of no less than 100000 hours.
⑥ Shaft seal: FUI series balanced single end mechanical seal, sealing surface material is silicon carbide/hard alloy; The O-ring is made of nitrile rubber; The remaining seals are made of 304 stainless steel material, which can adapt to a continuous working load of 620kPa and have a service life of not less than 30000 hours.
Liquid level sensor:
① Adopting a stable and reliable sewage level pressure switch. Convert the pressure of sewage into equivalent air pressure. When the pressure rises to the operating water level, the normally closed contact opens and the normally open contact opens, achieving functional conversion. After the pressure drops to the reset water level, the normally open contact opens and the normally closed contact opens, restoring the initial function.
② The sewage water level pressure switch joint control system provides local high alarm water level, pump on water level, pump off water level, and low alarm water level display, and realizes local automatic control of water pump start and stop, outputting liquid level signals to the control room EMCS, realizing remote monitoring, water level alarm, and liquid level meter fault alarm of the control room EMCS.
