Reasonable installation is the primary prerequisite for the normal operation of the scotch yoke pneumatic actuator. After using each kind of equipment for a period of time, reasonable and effective maintenance of the equipment will help us to better use in the later period. Below Beijing Ruitou's small edition, to tell you about the installation and maintenance of the scotch yoke pneumatic actuator.
Before assembly of actuators and valves, the measurement of valve torque should not exceed the required torque. After assembly of actuator and valve
Pneumatic actuator and valve are tested at the same time. The valve is pressurized to the rated sealing pressure. The actuator switches the two intake ports of the pneumatic actuator with the air source pressure of 0.4-0.7 Mpa or according to the user's need. The opening and closing of the pneumatic valve should be observed. There should be no stop and creep phenomenon. The switch should rotate flexibly and repeated tests should be carried out. Pneumatic actuator with solenoid valve

When debugging, the manual device (red button of solenoid valve) should be used to debug, and then power-on debugging. When manual operation is adopted, the power supply should be cut off first, and then the manual mechanism should be debugged. When using air source operation, the worm wheel and worm of the manual mechanism should be detached first, that is, the small handle should be transferred to the automatic position, and the pneumatic actuator should be the field instrument. Maintenance and maintenance should be carried out regularly

The air source of the actuator should be kept dry and clean. Regular discharge and sewage should be carried out for the air filters used in conjunction with the actuator in order to avoid entering the solenoid valve and actuator and affecting the normal operation. Under normal use, the air source should be inspected every six months and repaired every year. Water softener is a common equipment in life. It can reduce the hardness of water. It consists of tank, stainless steel or fiberglass reinforced plastics, control valve, salt suction tank, regeneration system and operation pipeline. When we use it, we may decide to pay attention to it according to our own wishes, but we seldom detect whether our use is correct or not, and even cause adverse consequences, resulting in shortened service life of softening water equipment and varying degrees of damage.
1. Maintaining the daily cleaning of equipment is indispensable. Keeping enough oil supply in the refueling part and not touching the pulley during operation can avoid accidents.
2. If the equipment is out of service for more than half a month, the discharge nylon pipe is raised to the exchange column so that it does not drain water. When it is not used for a long time, the residual salt in the salt tank and valve body should be cleaned. Lubricating oil should be added to the rotary valve and the transmission parts. It is strictly forbidden to induce the equipment. When the machine stops for more than half a month in summer and mildew season, the machine should be turned on for 60 to 120 minutes to prevent the microorganisms from mildewing in the resin tank. When restarting, pull the pulley with a hand, make the rotary valve rotate several times, and then put the water pipe in its original position after power is turned on.
3. When the equipment is in place, fix the bolts of the fixed motor, the bolts of the limit switch, the connection bolts inside and outside the distribution panel once more, so as to avoid accidents when the equipment is running. The upper and lower bolts of the wrench fixing block on the rotary valve should be fixed well to avoid collision of the exchange column as far as possible.
4. Do not adjust the relay time when the equipment is working. After the power supply is cut off, the cleaning equipment can be maintained, and the faults of motor, distribution panel and limit switch should be avoided fundamentally. At the same time, water supply and power supply are provided during operation, and all water source power supply is turned off when shutdown occurs. Users can not shut down in a short period of time at each downtime, they should also shut down water.
