Denmark hydraulic cylinder,lift car cylinder manufacturer,lift car cylinder(Denmark lift car cylinder,produced by Hengyu Hydraulic Co., Ltd)
lift car cylinder are widely used in Denmark,because of excellent temperature resistance,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed lift car cylinder for customers from Denmark.
The main role of the lift car cylinder: the lift car cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the lift car cylinder realizes reciprocating motion. The structure of the lift car cylinder has three categories: piston lift car cylinder, plunger lift car cylinder, swing lift car cylinder, piston lift car cylinder and plunger lift car cylinder to achieve reciprocating linear motion, output speed and thrust, swing lift car cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the lift car cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The lift car cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
The assembly work of the lift car cylinder has a great impact on the quality of the lift car cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.
In the process of using the lift car cylinder, sometimes such a problem will occur, the lift car cylinder can not act immediately after the instruction of the lift car cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil lift car cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.
Regular maintenance of the lift car cylinder includes: regular tightening, lift car cylinder fastening screws and gland screws, lift car cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the lift car cylinder once a year. Clean regularly, the lift car cylinder is cleaned every other year, and the seals are replaced while cleaning.
How to disassemble the big nut that excavate the oil cylinder piston of the excavator?
If you want to be safe, look for a special unloading place for this thing, which is an oil cylinder on top of a turntable with a large nut attached to the center of the turntable. If you're in the field just pin the head of the cylinder to one end, use a big homemade wrench to hold the nut in place, and then get a digging machine and push it down, and it opens.
The hydraulic cylinder is slow when moving forward and faster when moving back.
If the cylinder is single, it is slow when it is moving forward without the rod cavity, and fast when it is shrinking.
