Quality management and technical staff, including its subjective conditions, the level of knowledge, experience, and so a huge impact on the level of system security, reflected in all technical aspects, the commissioning and use of links is particularly evident. On the main technical and commissioning, use link aspects were discussed, and made a series of precautions. 1, the conventional security issues (1) electrical short circuit, leakage, electrical shock. Stationary hydraulic equipment is often installed in the workshop or laboratory to electricity and motor as a power source, power distribution cabinets and counters for the strong electric motor starting system, hydraulic system console is weak systems, to try to avoid the weak and strong electric hybrid fit together, causing electric shock; to ensure reliable electrical and hydraulic systems grounded mechanical housing, power distribution cabinets preferably with leakage protection; distribution cabinet and motor starter strong electrical contacts easy ignition, avoid flammable gas enters; conductor to avoid overlap between the strong electric conductors; regularly check short circuit protection device. (2) high speed moving parts. The most common is to drag pump motor, universal couplings used to connect the motor and pump, coupling generally use shell hooded, flying out of a hard object and prevents the operator accidentally touch the rotating coupling. Furthermore as gearbox, also need attention. 2, the system overpressure cause safety problems caused by overpressure system many reasons, the most direct and most fundamental reason is that the pipeline system or partial system overpressure valve is not installed, or install a safety valve but did not play security role. 2.1 After the system leakage and burst pipe overpressure from the weakest part of the first leak, such as pipe fittings, valve mounting surface plate or the like, sometimes cause burst pipe, and particularly for rubber hose, the end joints Easy to burst. Overpressure caused by the leak, including the pipeline burst, resulting in massive oil spray out if the oil temperature is high, it will directly burn human skin; Moreover, when sprayed oil everywhere, the staff panic run, easy to slip fall down; case of fire, but also bring fire. 2.2 Accumulator flying generally, to eliminate the pressure pulsation or as short-term energy, high-pressure side of the hydraulic system is often installed in parallel energy accumulator. And only one hydraulic accumulator interface, the oil under pressure, the hydraulic pressure of the hydraulic interface connector to withstand considerable tensile stress, the utilization of space considerations, standard connector design is not too large thickness to withstand tension capacity is limited, if the system pressure is too high, it will pull off the connector.
