KefeldHydrauliThere is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.
Therefore, in the hydraulic pipeline assembly line, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.
Kefeld.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.
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.
.Therefore, in the hydraulic pipeline assembly line, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.
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.
Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Hydraulic lifting table: the hydraulic lifting table is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing, chemical filling, etc., to meet the lifting needs of different operation heights,KefeldCylinder mounted hydraulic lifting platform, and can be equipped with various table forms (such as ball, roller, rotary table, steering, tipping, telescoping), and with various ways (separate, explosion-proof), it has stable and accurate lifting, frequent starting The characteristics of large load capacity effectively solve various lifting and lowering difficulties in industrial enterprises, making production operations smooth.
Therefore, the oil should be replaced regularly to ensure that the additives are effective. The filter can only absorb a limited amount of dirt particles and other impurities from the oil. Replace the filter according to the recommended cycle to keep the system clean.
Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color,KefeldMechanical hydraulic lifting platform, no bubbles, no cracks, and there should be no wrinkles,KefeldHydraulic mobile lifting platform, pits, paint leakage, 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.
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.
The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.
To consider its capacity, generally mobile equipment takes 2-3 times the high flow rate of pump Z, and fixed equipment takes 3-4 times.
device management.The hydraulic oil used in the system has the same brand and the oil temperature is between 45~80 ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more, clean the filter and add new oil after using a new filter element.
Low power consumption: Hydraulic elevators are driven by the pressure generated by their own weight the system should be drained while the oil is hot. After cleaning greatly saving energy. Long term improvement of various brand products such as elevator manufacturers, with complete designated products and quality assurance
The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.
Kefeld.Next, the hydraulic cargo elevator manufacturer will explain the maintenance of the mechanical equipment of the elevator: the brakes of each organization should be frequently checked and adjusted to ensure the clearance between the brake pads and wheels is sensitive and reliable. On the surface, there should be no dirt present. If there is dirt, it is necessary to wash it off with gasoline or thinner.
Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.
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.
