% of the elevator is evenly distributed at any position of the guide rail. The part bears the MAX load and should be stable at the MAX lifting height.
2The hydraulic lifting platform is manually mobile， and the lifting power of the platform is a two-machine or three-phase power supply. There are manual and electric， and a hand pump is also available for power failure. This series of platforms has flexible movement stable lifting， and convenient operation. Features， mainly used in factories， institutions shops and construction and decoration industries.
yHu Ge WenGenerally speaking，Domestic elevator for occasions where the lifting load is large and the lifting height is small，Aarhus Lifting platform hydraulic stationApplicable to which environments the jacking mechanism should be selected， and for the occasions where the load is small but the lifting height is large， the lifting mechanism should be selected. According to the initial structure of the jacking in order to meet the stability requirements， the size and lifting type of the oil cylinder are increased， and in order to achieve the same effective area as the jacking Suli， the oil cylinder is increased. If the latter is larger， a jacking mechanism should be selected.
If oil leaks from the oil pipeline check whether the standard interface is damaged， check whether the O-shaped hydraulic seal is damaged， replace the hydraulic seal or replace the standard interface as a whole.
WRitomeriOn-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.
HfThe seal of the drive shaft of the oil pump should be good. It should be noted that when replacing the oil seal，Domestic elevator the oil seal should be used instead of a single-lip oil seal， because the single-lip oil seal can only seal oil in one direction and does not have the function of sealing air. After the overhaul of a Liugong ZL loader in our unit， the hydraulic oil pump experienced continuous cavitation noise and the oil level of the fuel tank rose automatically. After inquiring about the repair process of the hydraulic oil pump， it was found that the oil contained excessive water in the hydraulic system to prevent water intrusion， which would cause Corrosion of hydraulic components， oil emulsification and deterioration， reduction of lubricating oil film strength， and accelerated mechanical wear. In addition to preventing water intrusion during maintenance， it is also necessary to tighten the cover of the oil storage tank when it is not in use， so that it can be placed upside down; oil with a large water content It needs to be filtered many times，Domestic elevator and the dried filter paper should be replaced every time it is filtered. If there is no special instrument for detection， the oil can be dropped on the hot iron plate，Aarhus Lifting platform hydraulic stationApplicable to which environments and the oil can be refilled only if there is no steam coming out and it will burn immediately.
Before work， the staff close the movable doors at both ends of the guardrail and start the bell. It is strictly forbidden to work when the movable door of the guardrail is open. In the operation of the hydraulic elevator， in case of special circumstances the emergency stop switch can be used to stop the hydraulic elevator， but in normal operation， it is forbidden to use the emergency stop switch to stop.
There is a self-stop phenomenon when running up and down， which is easily caused by the poor contact of the safety protection switch contacts.
pThe oil pipe is leaking oil. The tightness of the oil pipe is poor， causing the pressure to drop， and the hydraulic freight elevator naturally descends. It is recommended to carefully check whether the oil pipe is intact.
CAdvantages of civil engineering There is no need for a machine room above the well，Elevator Price_ Hydraulic ladder_ Household elevator_ Household elevator - elevator manufacturer and the top floor can be installed at a height of more than meters.
KTest resultsAs a special tool for high-altitude operations， the lifting platform has the characteristics of high efficiency， 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.
hUC. Check the hydraulic oil quality and oil level. When the lifting platform is raised to the highest level， the hydraulic oil level should be -mm higher than the bottom of the fuel tank. When the color of the hydraulic oil becomes dark， the oil is sticky， or there are foreign objects such as gravel in the oil， the hydraulic oil should be replaced in time. The hydraulic system of the lifting platform should use # hydraulic oil.
The user shouldFormulate the use details and safety precautions of hydraulic elevators， and hang them in obvious positions. Operators must be trained and assessed by the statutory management department， and can only engage in the operation of hydraulic elevators after obtaining a qualification certificate.
Cause: Severe oil leakage from manual pump and gear pump Elimination method: replace the oil pump seal ring Reason: The gear pump is damaged， and the pumped oil has no pressure Elimination method: Replace the gear pump Reason: The hydraulic oil is insufficient Hydraulic oil can be eliminated Reason: Circuit break Elimination method: Check the button contactor and fuse， etc. Elimination method: Filter blockage Elimination method: Replace or clean it Two situations: The input voltage of the electromagnetic coil is lack of V. The electromagnetic coil burns out and the spool is stuck. Elimination method: Overhaul or replacement can eliminate the cause and elimination method of the natural drop of the lifting platform. Reason: One-way valve leakage Elimination method: Check the check valve in the valve. It is assumed that the sealing surface of the check valve is dirty. Clean the check valve.
Variable costpFirst of all， the mechanical operation should be gentle and smooth: hydraulic freight elevator wholesale manufacturers should avoid rough mechanical operation， otherwise impact load will inevitably occur， causing frequent mechanical failures and greatly shortening the service life. The impact load generated during operation， on the one hand， causes early wear， fracture， and breakage of mechanical structural parts， and on the other hand， produces impact pressure on the hydraulic system， which will damage hydraulic components， oil seals， and the joints of high-pressure oil pipe joints and hoses Premature failure， oil leaks or cracked pipes， and now many people are beginning to choose the hydraulic lifting platform. When choosing a hydraulic lifting platform， because there are many types and many manufacturers， it is difficult to choose a good hydraulic lifting platform if you do not have some purchasing skills. Here are some purchases: The hydraulic lifting platform has been It is more and more accepted by people， because it has a wide range of uses， so more and more people and companies use it. Now we will talk about how to buy hydraulic lifting platforms. First of all， the partition in the traditional fuel tank cannot play the role of depositing dirt. A vertical partition should be installed along the longitudinal axis of the fuel tank. One end of the partition and the end plate of the fuel tank There is a gap between them to connect the space on both sides of the partition， so that the distance between the oil inlet and the oil return is the longest， and the hydraulic oil tank has more heat dissipation.
hJBefore installation， the installer should confirm the infrastructure such as the foundation and the shaft， pay attention to alignment， leveling， and alignment， and confirm that the foundation meets the requirements before construction.
Disadvantages of hydraulic elevators: The disadvantage is that the lifting height is limited， generally no more than floors; the elevator speed cannot be very fast， generally no more than m/s.
