XinfuMobile hydraulic lifting platformHow to maintain the seasons

The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). 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, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure,XinfuFreight elevator type hydraulic lifting platform, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.

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 the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure exhaust and clean the valve body several times, Make the damping hole unobstructed, repair or replace the spring,Xinfu6-meter hydraulic lifting platform, 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.

Xinfu.What technical issues are required for the installation of hydraulic freight elevators? The installation of hydraulic freight elevators is actually quite complex. If you do not understand the equipment pictures designed by the elevator manufacturer and the detailed situation of the hydraulic freight elevator designed by the elevator manufacturer, installation errors may occur, leading to equipment failure of the freight elevator! When installing hydraulic freight elevators, it is necessary to accurately calculate the size of the pit. The guide rail hydraulic freight elevator is a freight elevator composed of chains, guide rail torque tubes, and other components, mainly driven by the chain to assist in the upward and downward telescopic lifting of the freight elevator. The pulleys at the four corners of the countertop should be fixed on the surrounding guide rails. The entire elevator equipment is installed on the wall, and wall mounted installation is chosen to enhance the stability of the freight elevator. Choosing the appropriate wall size also requires careful planning.

The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed, resulting in unstable pressure regulation of the overflow valve, and the relief time of the overflow valve is too short, it is easy to cause the pilot valve performance of the overflow valve to be partially stable, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn, it should be replaced.

.Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.

Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.

Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.

There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch,XinfuSmall hydraulic lifting platform, it is easy for hydraulic cargo elevator manufacturers to cause this problem.

When the hydraulic cargo elevator needs to work, first connect the power supply and press the button to drive the motor of the hydraulic power unit to drive the gear pump. The hydraulic oil forms a certain pressure through the vane pump and passes through the oil filter; Explosion proof electromagnetic directional valve; Throttle valve; Hydraulic control one-way valve; The balance valve enters the lower end of the hydraulic cylinder, explosion-proof electromagnetic directional valve.

Regularly 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.

Encyclopedic knowledge.For hydraulic cylinders in hydraulic elevators and the return oil from the lower end of the hydraulic cylinder passes through the balance valve; Hydraulic control one-way valve; Throttle valve, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.

Reason: Cleaning method for internal leakage in the oil cylinder: Replace the sealing element of the oil cylinder. The lifting platform does not lower. Reason: The lowering valve is malfunctioning. Cleaning method: When pressing the lowering button, check whether the lowering valve is powered on. If there is no electricity, clean it as much as possible; If there is power, clear the malfunction of the lowering valve itself or replace the lowering valve. The sliding valve should be kept clean and.

Materials enter the production line at one end of the factory building, and the production process ends at the other end of the factory building with multiple separate platforms; This can greatly shorten the distance of material flow in the factory building.

The hydraulic lifting platform is a manually movable type, and the lifting power of the platform is a two machine or three-phase power supply. It has manual and electric power, and is also equipped with a hand pump for use in case of power outage. This series of platforms have the characteristics of flexible movement, stable lifting, and easy operation, and are mainly used in factories, government agencies, commercial stores, distribution box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.

When maintaining hydraulic components, the workbench must be clean. The purpose of the inspection tool.

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.

Xinfu.Surface paint quality: The paint should be smooth and flat have good adhesion with metal, have uniform color, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.

Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.

Separate: Loading and unloading on different platforms.
