Precautions for Use

1.Pre-operation Inspection

● Check the hydraulic oil level and quality before starting to ensure it meets the standard requirements.

● Inspect all pipeline connections for leakage, and confirm the mechanical reversing mechanism is flexible without jamming.

● Verify that the ceramic plunger and sealing parts are in good condition without damage or wear.

2.Operation Process

● Start the Mechanical Reversing Ceramic Hydraulic Plunger Pump for Filter Press step by step according to the standard procedure, avoid sudden full-load startup.

● Strictly operate within the rated pressure and flow range, prohibit long-term overpressure and overload operation.

● Observe the running sound, vibration and pressure gauge changes at any time during operation. If there is abnormal noise or severe vibration, stop the machine for inspection immediately.

3.Medium Requirements

● Avoid conveying ultra-high concentration sludge and large hard impurities to prevent plunger jamming and pipeline blockage.

● Control the proportion of solid particles in the medium to reduce abrasion to the ceramic plunger and seals.

4.Daily Maintenance

● Regularly replace the hydraulic oil to keep the hydraulic system clean and stable.

● Clean the inlet filter and pipeline impurities periodically to avoid clogging affecting feeding effect.

● Check the mechanical reversing device and wearing parts regularly, replace aging or damaged parts in time.

5.Safety Notes

● Stop the machine according to the standard sequence before maintenance, cut off the power supply and release pressure.

● Professional personnel are required for maintenance and debugging to avoid safety accidents and equipment damage.

Differences between Ceramic Hydraulic Piston Pump and Screw Pump

1.Working Principle

● Mechanical reversing ceramic hydraulic piston pump: Driven by hydraulic power, it uses mechanical reversing structure to make ceramic plungers move back and forth to complete suction and pressure delivery.

● Screw pump: It relies on meshing screws to rotate and form sealed cavities to push materials to realize conveying.

2.Pressure Performance

● Piston pump: It can output stable high pressure, strong pressure resistance, and still work normally when the filter press is blocked.

● Screw pump: The bearing pressure is low, the pressure is unstable under heavy load, and it is unable to meet high-pressure sludge conveying demands.

3.Medium Adaptability

● Piston pump: Equipped with ceramic plunger, wear-resistant and anti-corrosive, suitable for high-concentration sludge, sand-containing slurry and corrosive wastewater.

● Screw pump: The internal rotor and stator are easy to be worn by solid particles, only suitable for clean and low-viscosity materials.

4.Environmental Adaptability

● Plunger pump: Adopts full mechanical reversing design, without complex electric control, not affected by voltage instability, dust and humid environment.

● Screw pump: Matched with more electric control parts, easy to be affected by bad working environment and prone to electrical faults.

5.Energy Consumption

● Plunger pump: Reasonable power configuration, automatically adapts to actual load, low idle loss and obvious energy-saving effect.

● Screw pump: High overall power consumption, unable to adjust power intelligently, causing serious power waste in long-term operation.

6.Maintenance Cost

● Piston pump: Simple structure, few vulnerable parts, long service life of core parts, convenient parts replacement and low later use cost.

● Screw pump: The stator and rotor are easy to wear and need frequent replacement, with high maintenance frequency and high comprehensive cost.

7.Service Life & Application Range

● Piston pump: Stable operation, long service life, many products have been used stably for more than 7 years, mainly used for filter press sludge feeding in sewage, mining, chemical industry and other industries.

● Screw pump: Short service life in sludge treatment, mostly used for conventional clean water conveying, not suitable for long-term heavy-duty sludge treatment work.
