Notes for tubing replacement of hydraulic regulating platform

I. Matters needing attention in replacing hydraulic regulating platform tubing:

(1) The pipe should be as short as possible, preferably horizontal, flat and vertical, with fewer turns.

(2) In order to avoid tubing bending and reduce pressure loss, the bending radius of the tubing assembly of the hydraulic lifting platform should be large enough, and the pipe clamp should be set appropriately when the tubing is extended for a long time.

(3) Try not to cross the pipes. Please set the distance of the parallel tubes to more than 100mm to prevent contact vibration and make the joint easy to install.

Ii. Introduction of pipe joint in oil pipe and Matters needing attention:

(1) Summary: Pipe joint is the disassembly type joint between oil pipe and oil pipe, oil pipe and hydraulic components. It must be easy to disassemble and assemble, firm connection, reliable sealing, small external size, large circulation capacity, small pressure drop, good technology and other conditions.

(2) Types: There are many types of pipe fittings, including hard pipe fittings and hose fittings. According to the connection mode of hydraulic regulating platform pipe joint and oil pipe, there are three kinds of hard pipe joint: horn pipe joint, bite pipe joint and welding pipe joint. Hose fittings mainly include clamp hose fittings. The specifications and varieties can be found in the relevant manuals.

(3) The general connection mode of tubing and pipe joint in the hydraulic system of the hydraulic regulating platform. The connection screws for the line entry are standard metric conical screws and common fine tooth screws. Conical thread is widely used in middle and low pressure hydraulic system due to its own conical fastening and teflon sealing characteristics. Fine thread with good sealing performance, often used in high pressure systems.

(4) The end seal adopts combination gasket or 0 ring, sometimes there is also red copper gasket

(5) Most of the leakage problems in the hydraulic system appear in the connecting head of the pipeline system software, so the selection of pipeline raw materials, the clear way of the connecting head, the design of the pipeline system software and the installation of the pipeline must be carefully solved, in order to prevent the damage to the application quality of all hydraulic systems.

(6) After the connection, do leak detection to ensure the normal pressure, so as to eliminate potential safety hazards.

Conclusion: After the oil pipe is damaged, it may not be able to rise and fall, or reach the rated height, or even have safety hidden dangers. It is necessary to overhaul or replace the oil pipe in time and wait for the troubleshooting before the operation. This is not only responsible for yourself, but also for the safety of others. When a fault occurs in the hydraulic transmission system of the lift service platform, it is difficult to find the fault location immediately under most conditions. In hydraulic transmission systems, a variety of multicomponent phase AIDS and oils are mostly enclosed in waterproof sleeves and pipelines, which are not immediately visible as mechanical drives, and are less convenient to measure than control loops. In addition, the system software only in the operation of the main performance of the phenomenon of failure, some of the phenomenon of failure, its cause will have several types. This hydraulic press system is unusual and unique secret and multifarious function, along with the system software diversity and the total number of hydraulic press equipment to improve the significant performance. This brings difficulties to the inspection and elimination of faults. It is often impossible to correctly judge the cause of faults at one time, and it must be analyzed and checked repeatedly until the cause of faults is found.
