Product DescriptionThe working principle of the hydraulic discharger is based on Pascal's law, and the material is discharged by transmitting pressure through the hydraulic system. The hydraulic discharger is mainly composed of an oil pump, an integrated cartridge valve block, a one-way valve, a relief valve and an oil cylinder. The oil pump delivers the hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper or lower chamber of the oil cylinder through the one-way valve and the relief valve. Under the action of the high-pressure oil, the oil cylinder moves to achieve the discharge of the material. Rapid descent: When the electromagnet is energized, the pilot valve and the main cylinder reversing valve are connected to the system, and the hydraulic control one-way valve is opened. In the initial stage of the rapid descent of the main cylinder, the main cylinder piston descends rapidly under the action of its own weight. At this time, the flow rate of the hydraulic pump is small, which is not enough to supplement the volume of the upper chamber of the main cylinder, and a vacuum is formed in the upper chamber. The top filling tank refuels the upper chamber of the main cylinder under the action of atmospheric pressure to fill it with oil. When the piston of the main cylinder contacts the workpiece, the system starts to pressurize. Slow pressurization: When the slider contacts the workpiece, the resistance increases, the pressure in the upper chamber of the main cylinder increases, the hydraulic control one-way valve closes, and only the hydraulic pump continues to supply high-pressure oil to the upper chamber of the main cylinder, pushing the piston down slowly to pressurize the workpiece. The pressurization speed is determined by the flow rate of the hydraulic pump.Pressure holding delay: When the oil pressure in the upper chamber of the master cylinder reaches the preset value, the pressure relay sends a signal, the upper and lower oil chambers of the master cylinder are closed, and the hydraulic pump is in the unloading state. The pressure holding time is adjusted by the time relay controlled by the pressure relay. Pressure relief and quick return: After the pressure holding is completed, the time relay sends a signal, the electromagnet is energized, the master cylinder pilot valve is connected to the system, and the pressure relief valve connects the master cylinder reversing valve to the system in the right position. The hydraulic control check valve opens, and the oil in the upper chamber of the master cylinder is discharged back to the filling tank, and the excess oil is discharged back to the main oil tank through the overflow pipe. Application scenarios and maintenance of hydraulic dischargers Hydraulic dischargers are widely used in various occasions that require precise control of the discharge force, such as the shipbuilding industry, pressure vessel industry, chemical industry, etc. It is particularly suitable for various processes such as bending, forming, and flanging of center-loaded parts. In order to ensure the normal operation of the hydraulic discharger and extend its service life, it is very important to regularly check the cleanliness of the hydraulic oil, the sealing performance, and the wear of each component.Detailed PhotosEnergy: various battery slurries and pastes (lithium batteries, nickel-chromium batteries, nickel-metal hydride batteries, fuel cells, power batteries, etc.)Electronic appliances: solder paste, ceramic slurry, magnetic materials, silicone ink, electronic adhesives, PVC plastics, electronic and electrical device potting glue, hot melt adhesive, various precious metal powders and slurries.Chemicals: various sealants, adhesives (silicone sealants, polysulfide sealants, hollow glass sealants, waterproof sealants, structural sealants, anaerobic adhesives, stone adhesives, mold adhesives, etc.), synthetic resin rubber, inks, putties, abrasives (pastes), wax products, synthetic rubber, synthetic resins, various powder materials, ceramic pigments; cosmetics,Daily chemicals: moisturizers, lipsticks, lotions, gels, facial masks, mascara, foundation, nail polish, toothpaste, soap.Food: various pastes, pastes, seasonings, jams, chocolate pastes.Basic configuration: The hydraulic discharging machine is mainly composed of a bottom plate, a barrel positioning, a hydraulic cylinder, a crossbeam, a motor, a gear pump, a pressing plate and an electric control box, etc.Technical parameters: Volume: The capacity can be selected from 2-2000L Hydraulic power: 2.2KW to 7.5KW Pressing plate diameter: 350-650mm Pressing plate pressure: 15-200T Pressing method: single-column hydraulic or double-column hydraulic Lifting stroke: 450-750mm Pressing Stroke: 450-1400mmOptional functions:Discharging method: Up and down discharging methods can be selectedDischarging height: Customizable according to customer requirementsDischarging port: Can be connected to a metering device to achieve quantitative dischargingSealing method: The pressure plate sealing ring is close to the inner wall of the container, and no material remainsStirring barrel bottom structure: Head type or flat bottom type can be selectedPressure adjustment: Can be adjusted according to the material conditions and subsequent metering and filling equipment, and can work continuously under stable pressureBasic technical parametersProduct name and specification modelSpecifications of the press: 20L-1100LStructural formThe rack is a square frame, including inner and outer frames.Lifting methodCylinder self-liftingPressure methodUse hydraulic cylinder to drive the pressing plate to press the material.Pressure plate driving partsDouble acting cylinderPressure plateMatch with mixing barrel, built-in/split structureGuide formGuided by guide rod.Mixing barrel locking methodMechanical locking.Discharge methodLower discharge.Working voltageThree-phase 380VBasic technical indicatorsGas station motor powerPressure per unit area of the pressing plate2.2KW-11kw9kg/cm2-50kg/cm2Maximum press pressureSystem rated pressure8T-60T16MPa-22MPaCompany ProfileFAQQ1: The press machine cannot start. What may be the reason?Check whether the power supply is normal and whether the circuit breaker is tripped.Confirm whether the emergency stop button is pressed.Is the hydraulic oil or lubricating oil insufficient, Low liquid level may trigger the protection mechanism.Q2: How to deal with insufficient pressure during pressing?Check whether the hydraulic pump is working properly and whether the oil circuit is blocked or leaking.Adjust the pressure valve setting value to ensure that it meets the process requirements.Is the hydraulic oil deteriorated or contaminated? Replace it if necessary.Q3: What should I do if the operation panel displays an abnormal code?Check the fault code table in the equipment manual to locate the problem type (such as sensor failure, overload, etc.).Restart the device and try to reset it. If the error still occurs, please contact technical support.Q4: How often does the press machine need to be maintained?Daily maintenance: Check the oil level, clean the body, and tighten the bolts every day.Regular maintenance: Replace the hydraulic oil and filter element every 500 hours and check the wear of the seals.Q5: What are the wearing parts? How long is the replacement cycle?Common wearing parts: seals, filter elements, mold liners.Replacement cycle: seals (6-12 months), filter elements (3-6 months), depending on the frequency of use and working conditions.Q6: How to choose hydraulic oil?Select the viscosity grade according to the equipment manual.Anti-oxidation hydraulic oil should be selected in high temperature environments to avoid oil deterioration.Q7: Is the press machine too noisy when running?Check whether the hydraulic pump is air-intake or worn, and whether there are bubbles in the oil.Confirm whether the mechanical parts (bearings, guide rails) are insufficiently lubricated or damaged.
