Haoda6-meter hydraulic lifting platformThings to pay attention to when choosing

Regularly check whether each organization is functioning properly and whether there is noise. If problems are found,HaodaCustomized hydraulic lifting platform, they should be promptly cleaned up.

The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal, whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.

Haoda.Cylinder diameter and hydraulic oil flow rate. The speed of the hydraulic lifting device is inversely proportional to the cross-sectional area of the cylinder rod and directly proportional to the flow rate of hydraulic oil. When the hydraulic elevator runs slowly, priority should be given to the hydraulic oil flow angle.

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.

.Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective, replace it with a new valve.

Regularly check whether each organization is functioning properly and whether there is noise. If problems are found they should be promptly cleaned up.

The elevator itself has a simple structure and is easy to maintain, which has been favored by a large number of enterprises and individual customers. Hydraulic elevator is a multifunctional heavy loading and unloading mechanical equipment. The lifting system of hydraulic elevators is driven by hydraulic pressure, also known as hydraulic powered elevators.

. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional 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.

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

The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, 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.

Word of mouth recommendation.Hydraulic elevator manufacturers remind us that the basic principle of the hydraulic elevator speed control circuit is that the system often needs to adjust the movement speed of the hydraulic cylinder and hydraulic motor to adapt to the working cycle needs of the main machine. The speed of hydraulic cylinders and hydraulic motors depends on the displacement and input flow rate. It can be seen that changing the flow rate or displacement can affect the speed of the cylinder and motor.

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

For hydraulic cylinders in hydraulic elevators it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, speed regulation can change both the flow rate and the motor displacement.

New reference wiring diagram 2. Elevator leg noise. Mobile elevators should open the legs before operation. In this case the speed can only be adjusted by changing the flow rate. For variable displacement motors, if the legs lack butter, noise will be generated.

Scheme customization.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.

For example, setting anti fall and interaction can achieve good usage effects. This product is mainly used in various enterprise factories.

Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.

Haoda.Users should arrange dedicated personnel to operate hydraulic elevators, formulate usage details and safety precautions for hydraulic elevators based on their own situation, and hang them on the

Therefore, in the hydraulic pipeline assembly line,HaodaHydraulic guide rail type lifting platform, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.

A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, 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, throttle 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
