SongshanCustomization of hydraulic lifting platformPrinciple and Solution of Product Problems

The hydraulic freight elevator manufacturer tells you the reason and the elimination method: Reason: Overload Elimination method: Just reduce the load Reason: The oil return valve is not closed Elimination method: Tighten the oil return valve to eliminate Cause: The one-way valve of the manual pump is stuck， Return failure cleaning method: unscrew the valve port bolt of the oil pump， overhaul， clean， replace and clean the hydraulic oil to clean.

3The noise of the oil cylinder of the elevator is too low， and the air is sucked into the oil from the oil filter or the connection of the joint. The coupling is loose. The internal failure of the oil cylinder. Inhale the air or the oil pipe on the oil surface，Domestic elevator mix the air into the oil and remove it: the concentricity should be adjusted to within .MM，OpalCan hydraulic pressure automatically lift and lowerHow to choose production correct the coupling， repair or replace the oil pump， increase the oil volume， replace the rotating shaft seal ring at the position of the oil filter and the joint above mm Clean the oil filter screen， filter the oil and lock the oil return pipe， and the oil is mixed with air or the air in the hydraulic cylinder is not completely exhausted， and cavitation occurs under high pressure. cause loud noise. At this time， the air must be exhausted in time.

jSongshanWhat is a hydraulic lift?

The lifting table is placed on the horizontal support surface， and the concentrated load of the MAX load capacity is placed at any position mm away from the periphery of the workbench. After lifting times，Domestic elevator each stressed member must not be deformed or cracked.

HShinriroOn-site maintenance personnel should be available when checking the line to prevent safety accidents caused by turning on and off the switch without authorization when checking the line.

EkThe hydraulic transmission system uses liquid as the working substance， which cannot be controlled in the relative speed of the hydraulic system. Coupled with the expansion of the liquid， it is difficult to solve the strict reduction ratio.

It can reduce the investment cost: the top distance (OH) can be more than m， and the machine room can be set according to the building position， making the building layout more reasonable and beautiful， and reflecting the overall value. Simple troubleshooting: When the hydraulic elevator is shut down due to a power failure or fault， the management personnel can simply operate the steps to save people.

A. Check the lubrication and wear of the rollers， intermediate shafts and bearings; oil cylinder pins and bearings， boom hinges and bearings， etc. B. Fill the above components with lubricating oil. Extend bearing life.

dThe characteristics of the hydraulic cargo elevator are also more unique. The platform structure is compact and stable，Domestic elevator which can adapt to high-frequency continuous operation. The lifting height is stable and reliable， and can meet the stable lifting of large-ton cargo. To meet the requirements of different situations this is also the unique feature of the hydraulic cargo ladder，OpalCan hydraulic pressure automatically lift and lowerHow to choose production some lifting machinery is better without this， we have also witnessed this use， using the dock， it is a hydraulic cargo ladder， the improvement of the cargo has played a great help， It has shortened our working hours and improved our work efficiency， and it has played a great role in our production.

PFor the hydraulic cylinder in the hydraulic lift， it is unrealistic to adjust the speed by changing its effective area A (equivalent to the displacement). Generally，Elevator Price_ Hydraulic ladder_ Household elevator_ Household elevator - elevator manufacturer the speed can only be adjusted by changing the flow rate. For variable variable motors speed regulation can change both the flow rate and the motor displacement.

FPotential developmentOptional configuration of fixed lifting platform: fixed lifting platform can be equipped with auxiliary devices according to the requirements of use， and any combination can be made， such as safety protection device of fixed lifting platform; electrical mode; working platform form; power form， etc. The correct selection of various configurations can maximize the function of the lifting platform and achieve the best use effect.

iGThe hydraulic pump makes noise. When the hydraulic lift is raised， the hydraulic pump runs at high speed. If there is a problem with the gear or bearing of the hydraulic pump， the pressure of the hydraulic system will change periodically， which will also cause the hydraulic system to resonate and generate noise.

How much do you know about the classification of simple freight elevator lifting platforms? Hydraulic freight elevator manufacturers will tell you.

When moving or towing the hydraulic platform， the supporting legs should be retracted and the platform should be lowered to a low position. It is strictly forbidden for operators to move the platform when it is in a high position.

How much does it cost?lAs a special tool for high-altitude operations， the lifting platform has the characteristics of high efficiency， good safety， and convenient use. Sometimes you may encounter common faults during the entire work process. In order not to delay your use， we should grasp some maintenance A little knowledge， the wholesale manufacturers of hydraulic freight elevators below will briefly talk about the common faults.

EAt present， the above hydraulic freight elevators include guide rail type， mast type and other hydraulic lifting platforms that use single-acting cylinders as power. There is an unsolved problem， the descending speed varies with the size of the load. The larger the value， the greater the falling speed. Through the analysis of its structure and hydraulic system the reason can be found out. The hydraulic power unit uses a solenoid valve as a switch. When it needs to descend， the solenoid valve opens， and the hydraulic oil returns to the oil tank under the pressure of its own gravity. The faster the speed， the higher the speed of the platform as the load changes. How are customers performing in the experience?

The mobile type is a kind of cargo lifting machinery with good adjustment reliability and wide application fields， which is suitable for automatic production linesAdjust the relative height of the product workpiece during installation; high-altitude vibrating feeder feeding; component lifting during equipment installation; medium-sized machine tool trimming and cutting; warehouse logistics loading and unloading and handling sites and forklifts and other handling vehicle supporting facilities for rapid loading and unloading of goods， etc. . According to the application requirements， it can be equipped with auxiliary equipment for random combination， such as the safety device of the mobile lifting platform; the control of electric appliances; the mode of the working platform; the power mode， etc. Proper selection of various configurations can give full play to the function of the lifting platform and achieve practical results.

mSongshanThe hydraulic freight elevator manufacturer reminds you that there are two points that need to be paid attention to for the safety of the guide rail elevator operation， that is， the mechanical operation of the guide rail elevator should be gentle and smooth， and the cargo should be evenly loaded.

pVWhen installing， disassembling and adjusting the reversing mechanism， care should be taken to ensure that the centerline of the reversing mechanism reducer is parallel to the centerline of the gear， the meshing surface is not less than %， the main causes of noise are mechanical mechanism failures hydraulic system failures， electrical equipment or component failures， etc. Today， hydraulic freight elevator manufacturers will introduce to you the reasons for the noise of hydraulic elevators.
