The elevator is a kind of elevator equipment composed of traveling mechanism， hydraulic mechanism， electric mechanism and supporting mechanism. The hydraulic oil is under a certain pressure formed by the vane pump， and enters the lower end of the hydraulic cylinder through the oil filter， explosion-proof electromagnetic reversing valve， throttle valve， hydraulic control check valve， and balance valve， so that the upward movement of the hydraulic cylinder can lift heavy objects ， The oil returned from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic reversing valve， and the rated pressure relief valve is adjusted， and the pressure gauge reads the pressure gauge.
Knowledge popularization of scissor-type fixed lifting platform Superior performance: equipped with safety devices to prevent overloading of the lifting platform; equipped with protection valves to prevent hydraulic oil pipes from breaking; equipped with emergency descending devices for sudden power failures; Lock safety device.
SiroliAdvantages of operating cost: Low failure rate， due to the use of advanced hydraulic system and good methods， the failure rate of elevator operation can be reduced to a minimum. Less power consumption: When the hydraulic elevator goes down， it is driven by the pressure generated by its own weight， which greatly saves energy.
Guide rail lift (also known as freight elevator) is a non-scissor hydraulic lifting platform， which is mainly used in industrial plants， restaurants， restaurants， warehouses， docks， workshops and other places that need to move goods vertically between high-rise buildings above the second floor. The low height is especially suitable for sites where the site is not suitable for digging pits. What problems do we need to pay attention to in these places where elevators are used?
YacuibaThe contact opening and closing of the travel switch of each safety device must be reliable， and the contact arc crater should be polished in time.
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，SiroliChain guide rail lifting cargo elevator， 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， Long-term cooperation， mutual benefit and win-win. If you choose the wrong supplier， 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， containers， mold manufacturing， wood processing chemical filling， to meet the lifting needs of different operating heights etc.， and can be equipped with various table forms (such as balls， rollers， Turntable steering， tilting， telescopic)， linkage， explosion-proof)， with the characteristics of stable and accurate lifting， frequent starting， large load capacity， effectively solving the difficulties of various lifting operations in industrial enterprises， so that Production operations freely. The professional elevator factory has advanced technology， strict testing， more affordable prices， and more discounts are in progress， welcome to consult.
Hydraulic system: mainly oil cylinders， high-strength chrome-plated rods， Japanese NOK seals， self-made external integrated pump stations， oil pipelines， gear pumps， solenoid valves， etc. The Japanese NOK seal used in the oil cylinder has good wear resistance， which ensures that the oil cylinder series will not leak oil for a long time. The gear pump pumps the oil in the oil tank into the oil circuit and enters the oil cylinder， thereby driving the top of the rod and raising the equipment; The valve is used to adjust the oil output， the ascending and descending speed， and contains an emergency descending device to ensure that the guide rail hydraulic lifting platform can descend safely in case of an emergency.
Maintenance should be carried out on a regular basis and with designated personnel. It is divided into semi-monthly maintenance， monthly maintenance and annual maintenance. The content of each type of maintenance is different， but they must be done， and there are detailed records and signatures of both parties.
Brake operators of various mechanisms on the equipment should regularly check and adjust the gap between the brake shoe and the brake wheel to ensure flexibility and reliability. Long-term promotion of freight elevator factory， old brand， price advantage， quality guaranteed!
Quality inspection reportThe load of this series of products is divided into . to . tons， and can also be customized according to user requirements， with a load of up to tons.
Low cost: The cost is much lower than that of the scissor-type mobile lifting platform， so when purchasing a lifting platform，SiroliCargo elevator， you must consider the scope of use of the lifting platform，SiroliSimple lifting cargo elevator， the frequency of work， the load and other factors to choose a lifting platform that suits the work requirements .
Pay attention to check whether there are any broken wires and loose strands in the wire ropes of each part. If it exceeds the relevant regulations it must be replaced immediately. The maintenance of the wire rope should be strictly in accordance with regulations.
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， is there any relevant rule requirement?
Drain the hydraulic oil of the hydraulic lift and discard it. Tighten the joint to take out the oil filter. After cleaning， clean it with compressed air， then put it back into the oil tank， and connect the pipeline.
When installing， dismantling and adjusting the slewing mechanism， care should be taken to ensure that the centerline of the slewing mechanism reducer is parallel to the centerline of the gear， the meshing surface is not less than %， and the meshing clearance is suitable.
SiroliThe design of the hydraulic lifting platform is unreasonable. When the designer designs the cylinder barrel and rod if there is a problem with the design size and angle， it is necessary to confirm the technical strength of the manufacturer when working on a hydraulic lifting platform; what is the problem with the sound of the oil cylinder of the hydraulic lifting platform? Design drawings to make then there will definitely be problems in the later stage. Therefore， the angle of the oil cylinder is slightly deviated， it will cause the friction between the cylinder barrel and the rod， which will cause the sound; the seal quality of the hydraulic lifting platform is different， and the use of different seals will also affect the sound of the oil cylinder， and the seal with excellent material The continuous friction between the parts and the cylinder wall will cause the sound to be very loud， and long-term wear and tear may scratch the oil cylinder and cause oil leakage， so when the hydraulic lifting platform is used， pay attention to ask the manufacturer what brand and material the seal is used; In some cases of mechanical running-in， it is not ruled out that the above three situations are normal， and there will still be noises. If there is no problem after investigation， two-wheel traction， and car modified.
After the goods are transported， clean up the debris on the platform.
