Outdoor breaker hydraulic mechanism of the defects and improvements
Establish a correct idea, so as to achieve the purpose of improving safety awareness. 2,44 psychological approach is the use of psychological knowledge, according to the characteristics of mental activity and the objective law, to exert influence and control on staff. . Have their own needs, according to the demand will have different psychological reflect habitual violation occurred who is a psychology of luck, paralysis of thought, we should use for this kind of psychological and ideological education and administrative management, economic evaluation methods are different targeted work to do to eliminate the unhealthy psychology, does not occur in order to achieve the purpose of habitual violation of a 48-a method of ideological education and economic methods, administrative methods and psychological methods, have their own strengths, but also there are certain limitations, safety management must proceed from reality, for the different characteristics, play a role in various ways, to eliminate the subjective consciousness of the human safety the adverse factors, to ensure safety in production. 2.5 Management should strictly adhere to the strict management, and insisted earnestly, management, or direct impact on the strict safety awareness among employees. Strict management, the workers thought a kind of sense of urgency, the stress, especially for workers with low safety awareness, particularly good performance of its constraints. If lax management, the workers will have a relax in the thought, security awareness will decrease. (Verifying the date of closing :1999-10-01] ljI; L ---------- ......................---. .----------- a power safety technology Volume 2 Issue 3 2000, pressure drop 2.92MPa. The device set pump start is 27.3MPa, stop the pump pumps the value of 27.9MPa, Assuming 3512 oil temperature decreases down to 24.38MPa, petroleum associated pump to start, but much lower than oil at this time reclosing lockout value, the value of close to closing latch on the threat to the safe operation of equipment. 3 improvements manufacturers in solving this problem, the use of cylinder pressure in the lower part of installing a storage heater, but in actual operation, when the heater is cold frequently due to the long heating, easy to burn, the practical value is not great. I believe that the following two methods eliminate the defect, the better. 3.1 to replace them with micro switch 2YJ control pump start, then switch to the road in the oil pressure switch 1YK control; to replace them with micro switch 1YJ control pump outage, then use the oil on the road The pressure switch 2YK control,[link widoczny dla zalogowanych], shown in Figure 1. Pressure switch lYK, 2YK the start value of the parameters of the device specific settings. Bu b a 2 a 3 series gas piston:! inventory of 5-6 Aviation Oil piston rod clear / 8 Infinitive Open Mino, /, won a diagram hydraulic mechanism (before modification) 3.2 as shown in Figure 2, the improved device. In the upper part of the installation of a storage cylinder pressure regulator piston, cylinder storage pressure to switch to seal the top cover seal , sealed and stored pressure cylinder cover gasket with bolt increases in voltage between the piston and seal the cover to add a pressure regulator spring, cover the regulator piston and seal the space between the filling grease (Note to retain some space). regulator spring piston action of the pressure regulator is the original equipment hydraulic pump when the value of outage, the voltage regulator elastic spring piston cross-sectional area selected for the original device with the hydraulic pump when the value of outage product. Luan Lan grease cover plate 6 Jane № i8 l ammonia stored pressure '9 plug: 1 △ 10 Aviation Oil Sheng 'IYJ3YJ5YJ Ping Kui pressure ring 2 ring 【elections of the principle body j when the device or oil leakage circuit breaker operation for a certain volume of pressure oil,[link widoczny dla zalogowanych], the piston moves down as normal,[link widoczny dla zalogowanych], to ensure the pump to resume normal Dayou added that the pressure drop, due to the role of regulator pressure on both sides of the piston, the piston moves down regulator , compressed nitrogen volume, increased nitrogen pressure, to ensure that the oil is almost constant. When the ambient temperature changes, the nitrogen pressure change, pressure on the piston can also, automatically adjust the nitrogen pressure of lower motor to ensure the oil is almost constant. Grease is mainly used as a regulator piston and cylinder storage intramural pressure seal to prevent leakage of nitrogen,[link widoczny dla zalogowanych], when the running time is too long,[link widoczny dla zalogowanych], the regulator reduced the spring tension, you can open the sealed cover replacement regulator spring. the use of the improved device has the following advantages : (1) almost constant oil pressure under any circumstances, improve the safety and reliability of operation of circuit breakers (2) adjust the micro switch conveniently located and easy. (3) San switch 3YJ, 4YJ, 5YJ can keep only one When the abnormal pressure oil leak, a serious move down the piston rod is used to cut off the oil pump start circuit, disconnect the circuit breaker, closing loop, to prevent a lot of pressure oil leakage, the breaker points, closing time, the volume of oil pressure is not enough volume of oil required for operation and accidents.
