Remove the hydraulic oil tank filler cap, filter cover, hydraulic oil pipe and other parts to avoid dust when removing the system oil pipe. Clean the disassembled parts before opening them. When disassembling the hydraulic oil tank filler cap, first remove the soil around the tank cap,StocktonSmall hydraulic lifting platform, loosen the tank cap, and remove any remaining debris from the joint (do not rinse with water to prevent water from seeping into the tank). After confirming cleaning, open the tank cap.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.Stockton,The so-called input hydraulic energy refers to the input flow rate and pressure, and the output machinery is the speed and traction force during linear motion. All these parameters are achieved through changes in working volume, so hydraulic cylinders are a type of volumetric actuator. In order to meet the different needs of various machinery, hydraulic cylinders have different structures and hydraulic capabilities. According to hydraulic capacity, it can be divided into single acting hydraulic cylinders and double acting hydraulic cylinders. According to its structural characteristics, it can be divided into plunger hydraulic cylinders and hydraulic cylinders. Telescopic hydraulic cylinders and hydraulic cylinders are both referred to as the heart of hydraulic cargo elevators. How to maintain the heart of a hydraulic cargo elevator? Professional elevator manufacturers guarantee quality, service, and quality. Your satisfaction is our pursuit! Welcome to inquire by phoneThere is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal, the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, the noise can be reduced after running in for a period of time. If the rod is bent, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.Jablah, 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, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing,StocktonElectric hydraulic lifting platform, repeatedly adjust the pressure, exhaust and clean the valve body several times, Make the damping hole unobstructed, repair or replace the spring reduce the flow of the remote control port, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. . The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.Remember not to overload overload is the root cause of many faults.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

. 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.What are the requirements for the pit? This type of cargo elevator only needs - centimeters and does not require too much space. The installation of scissor type hydraulic cargo elevators is different from that of guide rail type hydraulic cargo elevators. The scissor lift cargo elevator has a large load-bearing capacity, and the pit depth needs to be set at around - centimeters. It can also be designed according to customer on-site needs.After hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.Free consultation,If the circuit of the device is not disconnected or lowered it is necessary to check the fuse for repair and replacement.Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± %.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,StocktonHydraulic mobile lifting platform, 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. 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, 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.

Do not use hydraulic lifting equipment with malfunctioning issues. The problem should be resolved before carrying cargo.Test conclusion,Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.High altitude work should always use tool bags. Tools with larger boarding bridges should be tied to sturdy components with ropes, and should not be placed randomly to prevent accidents caused by falling from a height.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.Stockton,Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)The development of elevators is at its peak, as many manufacturers have chosen more multi-story buildings to fully utilize the site, so they also need a device to facilitate the improvement of goods.Hydraulic cargo elevators have been used in some high-altitude operations in recent years, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes, becoming a better choice for some high-altitude operations. However, such as height and improving the quality of goods, which have certain constraints.
