哪里的电动试压泵厂家安全可靠

 DSY型电动试压泵主要由止回阀、往复泵、进水管路及工作胶管等部件组成。
 
1、工作胶管:是DSY型电动试压泵与试压管路的连接件,其一端与止回阀部件出口相连,另一端与试压管路进口相连,胶管接头的密封可采用紫铜垫或O型密封圈及橡胶垫。
 
2、止回阀:主要由四通体及单向阀组构成。该部件与往复泵出口相连,其作用在于,当往复泵停机后仍能保持试压管路系统的压力,在该部件上还装有压力显示装置及排气阀,压力表所显示压力为往复泵运行及停机后的试压系统压力。排气阀的功能是:排除DSY型电动试压泵起动运行时管路中的空气及试压结束后卸除系统压力。
 
3、进水管路:由滤网及输水管等组成,它完成将介质过滤并向泵输送介质的功能。
 
4、泵:DSY型电动试压泵为单活塞泵,由单相电机驱动,并与电机直连,分为动力端和液力端两部分。
 
(1)液力端:由泵体、缸套、活塞、吸入阀、排出阀、密封副及安全阀等组成。连杆带动活塞杆及固定在活塞杆前端的活塞往复运动,将介质吸入泵内并排出。安装在泵体上的安全阀是系统压力过载保护装置,当系统压力达到安全阀起跳压力时,安全阀将*一般不应随意调整。
 
(2)动力端:由连接体、偏心套、连杆等组成。偏心套直接装在电机轴上,电机旋转,通过偏心套带动连杆小头及与其相连的活塞杆作往复直线运动。
