The motor connection is wrong. When the delta connection motor is wrongly connected into a star shape， the motor still runs with full load， and the current flowing through the stator winding will exceed the rated current，Roermond Fixed hydraulic lifting cargo elevator， and even cause the motor to stop by itself. If it overheats， it will burn out. When the star-connected motor is wrongly connected into a triangle， or the motor with several coil groups connected in series to form a branch circuit is connected in parallel with two branches， it will cause the winding and core to overheat， and in severe cases， the winding will be burned.
Roermond Hydraulic lifting freight elevator， cargo elevator， is mainly designed for transporting goods， usually accompanied by people. The freight elevator car has the characteristics of long and narrow. A vertical lift powered by an electric motor， fitted with a box-like gondola. Fixed lifting equipment serving specified floors. It has a car that runs between at least two vertical columns of rigid rails. Let"s take a look at its daily maintenance skills: Daily maintenance skills for hydraulic lifts The newly installed hydraulic lifts first have a warranty period from the elevator manufacturer (generally -- years).
Low cost: The cost is much lower than that of the scissor-type mobile lifting platform， so when purchasing a lifting platform， you must consider the scope of use of the lifting platform， the frequency of work，Roermond Cargo elevator， the load and other factors to choose a lifting platform that suits the work requirements .
QingzhouSecondly， there must be no dirt on the friction surface. If there is dirt， it needs to be washed off with gasoline or thinner; the gear box， gearbox， external gear and other parts of the equipment and the hydraulic oil must be in accordance with the requirements in the table; Correctly maintain the hydraulic guide rail lift. Regularly check whether the wire ropes in each part are broken or loose. If this phenomenon is found， replace them in time. If there is any looseness， it should be tightened in time. The connecting bolts of the equipment should be checked for tightness when the body is under pressure. All connecting shafts should be equipped with cotter pins; check whether each mechanism is operating normally， whether there is noise or failure ， to eliminate all faults in a timely manner; when installing，Roermond Professional cargo elevator， it is necessary to pay attention to the parallelism between the reducer and the center line of the gear， and the appropriate meshing gap; conduct a comprehensive inspection of the equipment regularly， whether the wires and cables are If there is damage， whether the motor is overheated， replace it in time and continue to run after troubleshooting; ensure that the bearings of the motor， each box， distribution box and brushes must be kept clean， restaurants， restaurants， etc. The low height can be made to -mm. The advantage is that it can be placed directly on the ground without digging pits， reducing engineering construction costs and there is no need to set up hanging points on the top， which is safe. Reliable; the hydraulic lifting platform adopts hydraulic transmission mode， and can be non-calibrated according to customer needsSeveral types: Motor winding open circuit. When one of the motor windings is disconnected， or one of the parallel branches is disconnected， the three-phase current will be unbalanced and the motor will overheat.
The water cooling of the hydraulic station is generally tube-type water cooling， and its type selection is based on the heat load to calculate the heat exchange area， while its air-cooled elevator is carried out by using an air cooler， and it is The heat transfer capacity is calculated according to the heat load， and then the type selection calculation is carried out under the condition that the flow rate can be satisfied. Therefore， these two kinds of cooling are not the same， and there is a big difference. Long-term promotion of freight elevator factories and other， you will be overwhelmed with all kinds of after-sales troubles in the later stage. Recently I have seen many netizens report the problem of very loud oil cylinders. Today， the platform is level with the ground， does not occupy the ground space， and does not affect the passageway.
The operating rod is heavy. The operating rod mechanism is faulty. Check， adjust， and replace unqualified parts; clean the valve parts; check the hydraulic oil cleanliness and the valve core is stuck (manufacturing， installation problems， dirt problems)
Ensure good power supply at the installation site， install a separate distribution box， and the leakage switch must meet the requirements for construction elevators when used in the distribution box. If the construction elevator installed is frequency conversion， the leakage switch should be adapted to the frequency converter when selecting the leakage switch .
OK or not?Prepare the foundation according to the foundation plan， pay attention to the alignment， leveling， and alignment to ensure the level of the foundation and various requirements for use.
Secondly there must be no dirt on the friction surface. If there is dirt， it needs to be washed off with gasoline or thinner; the gear box， gearbox， external gear and other parts of the equipment and the hydraulic oil must be in accordance with the requirements in the table; Correctly maintain the hydraulic guide rail lift. Regularly check whether the wire ropes in each part are broken or loose. If this phenomenon is found， replace them in time. If there is any looseness， it should be tightened in time. The connecting bolts of the equipment should be checked for tightness when the body is under pressure. All connecting shafts should be equipped with cotter pins; check whether each mechanism is operating normally， whether there is noise or failure ， to eliminate all faults in a timely manner; when installing， dismantling and adjusting the slewing mechanism of the equipment， it is necessary to pay attention to the parallelism between the reducer and the center line of the gear， and the appropriate meshing gap; conduct a comprehensive inspection of the equipment regularly， whether the wires and cables are If there is damage， whether the motor is overheated， replace it in time and continue to run after troubleshooting; ensure that the bearings of the motor each box， distribution box and brushes must be kept clean， and the travel switch points of each safety device must be safe and reliable.
Many customers think that the operating power supply of the hydraulic lifting platform is below the safe voltage of V， and there will be no electric shock. They are wrong. Normally， there will be no electric shock， but if there is improper operation， it will still be very dangerous. So how can we effectively prevent the occurrence of electric shock accidents? Today， the editor will share safety knowledge with you.
The scissor-type fixed lifting platform is a kind of transportation and handling equipment for transporting goods from a certain height to another height. After the operation is completed， the platform is level with the ground， does not occupy the ground space， and does not affect the passageway.
Quality recommendationThe safety device of the guide rail hydraulic lifting platform The mechanical part of the guide rail hydraulic lifting platform mainly includes the hydraulic system and the mechanical device.
Application and characteristics of stage lift: stage lift is also called lifting stage， stage lift is specially installed on the stage， and used for stage lifting and rotation is called stage lift. It has multiple functions such as lifting， rotating， and tilting， and adopts self-locking interlocking， travel switch， mechanical limit， hydraulic explosion-proof and other protective measures.
Avoid working in an environment. In the event of rain， snow and other weather， the use of the hydraulic lifting platform should be stopped to prevent the occurrence of a short circuit， resulting in electric leakage and electric shock; non-professionals are strictly prohibited from disassembling electrical appliances such as hydraulic lifting platforms. In the event of an accident， you can’t disassemble without permission to eliminate the cause. You must report to the manufacturer for repair in time， and the manufacturer will guide you to complete the inspection or send someone to repair it; do not disassemble the appliance without permission! Professional elevator factory guarantees quality， guarantees service. Guarantees quality. Your satisfaction is our pursuit! Welcome to inquire.
Roermond Goods should be stacked on the platform and not tilted. When the freight elevator goes up and down beyond the range of the platform， no one should stand around to watch.
Always check the connections of the various parts of the hydraulic lift， and tighten them if they are loose. The tightness of the connecting bolts of the body should be checked when the body is under pressure.
Naturally connect the motor to the lift. When connecting it must be ensured that the concentricity of the output shaft of the elevator is consistent with that of the input shaft of the motor， and that the outer flanges of the two are parallel. If the concentricity is inconsistent， it will cause the motor shaft to break or the elevator gear to wear.
