Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.Haoda,Setting requirements: Construction electric elevators should be equipped with up travel (limit) switches.In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between m and m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least mm above the ground.Hague, the protective measures taken should comply with the specification requirements.Later, when there is a major malfunction of the lifting platform,HaodaWroclaw, it should be repaired by professional personnel as soon as possible. After the malfunction occurs, it should not be used again to avoid accidents, personnel and property losses.The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking,HaodaFrankfurt am Main, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.
Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly, which is better than stacking them in the center of the cargo stacking area of the cargo elevator to avoid imbalance between the two ends of the stacking area. Eventually during the operation of the electric elevator, it may cause the electric elevator to lose balance. After the goods are stacked completely, ropes should be used to lock the goods, so that they are not afraid of the goods during the lifting process; Careless; Scattered downThe shutdown device (emergency stop switch) should be non automatic reset type.Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, it can cause the car to descend to the nearest floor position and open the doorTo ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB&flash; The rotation of the SB motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.Sales DepartmentThe verticality of the guide rail frame should meet the requirements of the specifications.The pressure joint between the pipe joint and the rubber hose fails prematurely, causing oil leakage or pipe explosion. The oil temperature rises due to frequent action of the overflow valve.The function of the lifting platform in a theater is roughly as follows: the main lifting platform arranged in the main performance area of the stage is mainly used to quickly change the scenery. Typically, with&quo; Product; In the music and dance theater stage arranged in a zigzag pattern, the lifting platform, side car platform, and rear car turntable perform a rapid transformation of the entire or partial scene. This arrangement allows for rapid switching of three full sets.Haoda,The verticality of the guide rail frame should meet the requirements of the specifications.The use of standard section connecting bolts should comply with the user manual and specification requirements.The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve,HaodaKilkenny, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).
A good seller, even a novice, a lot of Haodaqinghuangdao don’t understand. Fortunately, the seller has patient guidance on the other end of the computer, and I have a sense of accomplishment, and fina
It's worthy of praise, really good, Haodaqinghuangdao I like it very much.
To live up to the boss's expectations of me, I will definitely write down my own evaluation objectively, fairly and truthfully, Haodaqinghuangdao is indeed very good, thank you!!!
Haodaqinghuangdao Not bad, the price is worth it, just right.
