made of
swirl wheel, installed between outer diaphragm plate and inner diaphragm plate.
The pump may de working dy self-suction, prior to first starting it should fill up the pumpbocy(
1 )with water, since the position for pump suction pipe and pump discharge pipe
are also higher than than of
pumpdody, so that it ensures accumu-lating water in the pumpbody chamber after
the pump was stopped, and while the pump was started again, it can be operated by
self-suction actiou without filling up with water.
6、泵均采用機械密封裝置，泄漏量每小時小于1O毫升。
pumps for all types use mechanical
sealing gland, and its leakage per hour is less than 10 ml.
7、1.5 CWX-2A與1.5 CWX-2及1.5CWX-4A與1.5CWX-4其主要性能相同，但結合有異。1.5CWX-2/4 A型泵帶托架，具有工作平穩(wěn)，使用壽命長的優(yōu)點。托架內灌入20*機油或相近的潤滑油以潤滑滾動軸承油位應在探針的刻度之間，一般情況下，每半年更換一次，1.5CWX-2/4型泵與電機直聯(lián)，具有外形體積小，重量輕，結構簡單的優(yōu)點。
The main characteristics of pumps model
1.5CWX-2A, 1.5CWX-2 ,1.5CWX-4A and 1.5CWX-4 are of the same, but different in construction. The pump model 1.5CWX-2/4A
has bracket, and has the advantages for operating smoothly and longer uselife. 1hto the
bracket Should fill with engine oil NO.20 or similar lubricating oil so as to
lubricate the ball-bearing(16),
the height for oil levrl should be
filled to between the scales of probc. In uormal conditions, the oil should be
replaced at every 6 months. The pump model

8、起動前的準備和運轉維護：
preparation and maintenance for
operation prior to starting:
(1)首次起動前應向泵內注滿水，如已經工作過則不需注水，此時應打開吸入閥和壓出閥。
It should fill up the pump with water befoie the first
starting,and if the pimp has operated for sometimes, filling with water is not required,
but it should epen the sucion valve and the pressing-discharge valve.
