San JoseHydrauRegularly inspect the hydraulic lifting equipment of the upper and lower materials to ensure the safety of the rail type elevator and the safety of the material supply to the rail type lifting platform.
. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve and explosion-proof electromagnetic directional valve. In order to ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve and balance circuit are installed on the return oil circuit to maintain pressure and ensure that the descent speed is not affected by changes in heavy objects. The throttle valve regulates the flow rate and the lifting speed. To ensure safe and reliable braking and prevent accidents, a hydraulic one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking when the hydraulic pipeline bursts. Install an overload sound alarm to distinguish between overload or equipment failure.
San Jose.The load of goods and the tonnage of goods transported at once also affect the lifting speed. The optimal value for transporting goods on a lifting platform is speed. If it is too heavy, it will affect the speed. The above is the knowledge about adjusting the lifting speed of hydraulic cargo elevators hoping to be helpful to everyone. Long term improvement: The manufacturer has a complete range of products,San JoseCan hydraulic pressure automatically lift and lower, excellent quality, and discounted prices
Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
.Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
The lifting platform is placed on a horizontal support surface, and the concentrated load of MAX load capacity is placed at any position 300mm away from the periphery of the workbench. After lifting 100 times, each load-bearing component must not have deformation or cracks.
Lifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving, and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, and there should be no leakage at all components, pipelines, and joints.
Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
When working on scaffolding without scaffolding or without railings, if the height exceeds 5 meters, safety belts must be used or other reliable safety measures must be taken.
The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
retailer.After the pre installation is completed, the pre installed equipment should be fixed, and the positions of cables,San JoseCylinder mounted hydraulic lifting platform, oil pipes, and components such as the pre installed frame should be confirmed to be correct before reinforcement work can be carried out. Reinforcement requires welding or screws, and the hydraulic cargo elevator after reinforcement has robustness and safety.
There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, Make the damping hole unobstructed, repair or replace the spring, reduce the flow of the remote control port, replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. 5. The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.
Separate: Loading and unloading on different platforms.
The hydraulic pump produces noise. When the hydraulic elevator rises the hydraulic pump runs at high speed. If there is a problem with the gears or bearings of the hydraulic pump, which causes periodic changes in the hydraulic system pressure it will also cause resonance in the hydraulic system and generate noise.
Product line.The installation personnel should have the qualification for installing hydraulic cargo elevators, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.
Many operating factories often require the use of hydraulic cargo elevators, which can be lifted and lowered, making it very convenient to use. Many people do not know the knowledge of hydraulic cargo elevator lifting and adjustment. If they understand this knowledge, it will be helpful for future maintenance. The power unit of the fixed chain elevator for hydraulic lifting of cargo elevators drives the hydraulic oil to generate pressure, causing the oil cylinder to move back and forth to drive the lifting platform, thus achieving the adjustment of lifting speed. The power unit adjustment, whether it is a scissor type lifting platform or a track type lifting platform, is composed of the power unit and the oil cylinder. The power unit is manufactured with four outlet holes, which can be adjusted in size to increase or decrease the hydraulic oil flow rate of the oil cylinder, Adjustable motor speed or electro-hydraulic proportional valve to adjust hydraulic oil flow rate; The longer the oil pipe and hydraulic oil pipe, the longer the rise time. So during installation, try to minimize the length of the pipeline within the allowable range of the design; On the basis of adjusting the power device, the size of the oil pipeline can also be adjusted, and corresponding adjustments can be made while ensuring that the equipment meets normal demand and safety.
The lifting platform is a multifunctional heavy loading and unloading mechanical equipment, which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.
San Jose.Pay attention to checking each steel wire rope for signs of broken wires and loose drums. If it exceeds the relevant rules, it is necessary to replace it immediately. The protection of steel wire ropes should strictly follow the rules of GB5144-85.
A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism,San JoseCustomization of hydraulic lifting platform, hydraulic mechanism, electric mechanism, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.
Load bearing capacity: The lifting platform is placed on a horizontal support surface, and the workbench is evenly loaded to 125% of the maximum load capacity. After lifting 100 times, each load-bearing component must not have deformation or cracks.
