AF泡沫泵能不能改成機(jī)械密封樣式
機(jī)械密封
1)機(jī)械密封的主要構(gòu)件
機(jī)械密封也稱端面密封，典型結(jié)構(gòu)如圖165所示，機(jī)械密封由以下幾部分組成:
(1)主要密封件:由與軸-起旋轉(zhuǎn)的動環(huán)和固定在壓蓋內(nèi)的靜環(huán)構(gòu)成一對摩擦副,起到徑向密封作用。
(2)輔助密封件:包括O形環(huán)、V形環(huán)、U形環(huán)、楔形環(huán)等。
(3)緊固件:包括彈簧座、固定螺釘、壓蓋等，起到靜、動環(huán)定位，緊固和盛裝的作用。
(4)彈性件:包括彈簧、波紋管、隔膜等,使動、靜環(huán)貼合,起到預(yù)緊、補(bǔ)償、緩沖的作用。
(5)傳動件:包括傳動環(huán)、傳動件、傳動銷等，能帶動AF泡沫泵動環(huán)隨軸一起旋轉(zhuǎn)。
Can AF foam pump be changed into mechanical seal style?
Mechanical seal
1) Main components of mechanical seal
Mechanical seal is also called face seal, and its typical structure is shown in Figure 165. Mechanical seal consists of the following parts:
(1) Main seal: it is composed of a pair of friction pairs which are rotating with the shaft and stationary rings fixed in the gland, playing a role of radial sealing.
(2) Auxiliary seals: including O-ring, V-ring, U-ring, wedge ring, etc.
(3) Fasteners: including spring seat, set screw, gland, etc., which play the role of static and dynamic ring positioning, fastening and filling.
(4) Elastic parts: including springs, bellows, diaphragms, etc. to make the dynamic and static rings fit together and play the role of pre tightening, compensation and buffer.
(5) transmission parts: drive rings, transmission parts, transmission pins, etc., can drive the AF foam pump ring to rotate along the shaft.
