進口聚酰胺氣動塑料執(zhí)行器PAW
-雙作用
加壓的氣體通過講氣路A(標號2,根據(jù)ISO-5559-2,位置1)進入,推動兩個相對的活塞到達氣缸左右兩端,利用齒輪齒條系統(tǒng)使執(zhí)行器軸旋轉(zhuǎn)900,使其開啟。
加壓的氣體通過氣路B(標號4,根據(jù)ISO-5559-2,位置2)進入,推動活塞進行反向運動,回到其初始狀態(tài)(關閉)。
-Spring return:
These models contain compressed springs,situated between the capes and the pistons,The pressure made by these springs keep the pistons in POSITION2(CLOSED).Introduction of air to channel “A”(NO.2,according to ISO-559-2)
Displaces the two pistons to the ends,pressing the springs even further to POSITION 1.When the air pressure ceases,spring push the pistons to their initial position (CLOSED)Depending on the position which the actuator is mounted onto the valve,we will obtain that it works NORMALLY OPEN(N.A)or NORMALLY CLOSED(N,C.).
-單作用(彈簧復位)
這一系列執(zhí)行器內(nèi)置彈簧,至于端蓋和活塞之間,彈簧的彈力使活塞處于位置2(關閉)轉(zhuǎn)臺。加壓的氣體通過氣路A(標號2,根據(jù)ISO-5559-2,WEIZHI 1)進入,推動兩個相對的活塞到達氣缸作用兩端,從而推動彈簧到達位置1(開啟)。在失氣的情況下,彈簧的彈力推動活塞回到初始狀態(tài)(關閉)。根據(jù)執(zhí)行器安裝在閥門的位置的不同,可以達到常開(N.A)或常閉(N.C)的工作狀態(tài)。
MOUNTING POSITION 安裝位置 | OPERATION操作狀態(tài) | |
ACTUATOR執(zhí)行器 | VALVE閥門 | |
CLOSED關 | CLOSED關 | N.C. 常閉 |
OPEN開 | OPEN開 | |
CLOSED 關 | OPEN開 | N.A. 常開 |

1.7-Identification
All PRISMA pneumatic actuators carry on the rear side on indentification label with the follwing description:
每個PRISMA 執(zhí)行器的背面都有其專屬的標簽如下圖所示:
P,pp,p1和PH系類標簽 PA系列標簽
Besides,the spring return models carry label of ATTENTION on each cap:
除此以外,單作用(彈簧復位)執(zhí)行器兩端分別貼有“小心”的字樣,一方拆卸時,氣缸里的空氣沒有*釋放,使得彈簧突出彈出。
2-COMMISSIONING 試運行
2.1-Transport and installation,運輸和安裝
-At the of transportaion and handling pay attention and care as any damage in the external coating in models P,PH and PG could reduce the resistance of the pneumatic actuator against the extermal agents.
當運輸和搬運的過程中,請小心,并注意不要損壞了P,PH和PG系統(tǒng)執(zhí)行器的外涂層,若損壞了將會對執(zhí)行器的耐腐性產(chǎn)生影響。
-Do not remove the obstructers which protect he threads of connection until th moment of operation.
在通氣前,請勿拆掉氣孔中的白色擋塞,這是為了保護通氣口的螺紋。
-Be sure that the air supply is sufficiently clean and free of solid particles in suspension which in the long run could damage the internal parts of the device.
保證氣源的足夠干凈,避免有固體懸浮顆粒,以免通過氣管進入氣缸內(nèi)部,損壞氣缸內(nèi)部元件。
-Check“on site that the air supply pressure is the necessary (normally 6 bar).
保證足夠的氣源壓力(通常6bar).
-Even though it is not strictly necessary, a slight lubrication of the air fed prolongs the life of the pneumatic actuators.
輕微的潤滑可以延長執(zhí)行器的使用壽命(雖然不是必須要求)。
2.2-Mounting noto the valve 安裝在閥門上
Make sure that the working position of the actuator regarding the valve is the correct one (N.A.or.N.C.)(See 1.6)
保證閥門和執(zhí)行器的工作狀態(tài)正確(常開或常閉)(見1.6)
-PRISMA pneumatic actuator can be mounted indistinctly parallel or perpendicular position to the pipe on any N.C.as well as N.A.operation. Make sure that the position is the desired one.
PRISMA執(zhí)行器可以平行或垂直安裝在管道上。根據(jù)您自己的要求來確定安裝位置。
-In case of Spring Return actuators, do not remove the FITTING-FILTER fixed in the upper air feeding connection expect if a Namur solenoid valve should be installed as it avoids the entry of external elements(dust,water,etc)in the spring chamber.
若選用單作用執(zhí)行器,不要取下其中一個氣孔中的擋塞,除非是需要安裝電磁閥。這樣是為了防止外部的灰塵或是水分進入氣缸內(nèi)部。
2.3-Feeding 氣源
-PRISMA peneumatic actuators can normally operate between 3 and bar according to models.Their standard operation is at 6 bar,for pressure lower that 6 bar,p;ease consult.
PRISMA 氣動執(zhí)行器的氣源壓力范圍是3到8bar.標準氣源壓力是6bar,若氣源壓力低于6bar,請另詢。
3MALNTENANCE 維護
3.1-Preventive maintenance 預先維護
To assure the right operation of the equipment ACTUATOR-VALVE,we recommend:
為了確保氣動閥門運行正常,預先*:
3.1.1-EVERY YEAR 每年
-Check that the air feeding is clean and at he necessary pressure :
確保氣源干凈和充足;
-Ddpending on the nature of fluid flowing through the valve and with the appropriate fequency,it will be necessary to clean the interior of the valves of eventual incrutations which would increase the resistant torque.
根據(jù)閥門介質(zhì)的特性,要保持閥門過濾部分的干凈,以免增大閥門扭矩。
3.1.2-EVERY TWO YEAR 每兩年
-Depending on the number of cycles perfomed by the equipment,it will be convenient to replace all the o*rings in order to avoid any loss of torque of the pneumatic actuator.
In internal tests carried out on our test bench,the correct operation of the device is maintained fater more than1.000.000 complete,cycles(open-close)under the following conditions.
