手轮式螺杆启闭机的特点
手轮式螺杆启闭机的特点
特点：
Features:
LQ型螺杆式手电两用启闭机，在结构设计与使用性能上具有以下特点：
The LQ type screw type flashlight dual purpose hoist has the
following characteristics in structural design and service performance.
本机为手电两用，可根据用户需要，配备电动装置，并配备摇手把，供手动使用。
This machine is dual purpose for flashlight. It can be equipped
with electric device according to users' needs and equipped with hand
crank for manual use.
本机设计生产执行标准为水利部、能源部SD298—88《LQ型螺杆式启闭机技术条件》。各部零件执行国家标准。
This machine is designed and manufactured as the standard for LQ
screw hoist technology of Ministry of water resources and Energy
Ministry SD298 - 88. The national standards for the parts of each part
are carried out.
本机采用蜗轮、蜗杆变速，螺母或螺杆旋转，使闸门作上下运动，达到启（闭）闭（启）的作用。
This machine uses worm gear, worm gear, nut or screw to rotate, so
that the gate moves up and down to achieve the function of opening
(closing) and closing.
可根据用户要求，设磁力锁装置，以防他人开启。
According to the requirements of users, a magnetic lock device is set up to prevent others from opening.
螺杆长度可按用户要求生产，双吊点吊点距按用户要求设计。
The length of the screw can be produced according to the
requirements of users. The distance between two lifting points is
designed according to user requirements.
安装调试
Installation debugging
启闭机在出厂前已加足黄油，一般在使用一段时间后，要根据情况随时加油润滑。
The hoist has been filled with butter before leaving the factory.
After being used for a period of time, it should be lubricated at any
time according to the situation.
2、启闭机的安装方法和一般机械相同，安装前一定要检查各部零件是否良好，螺栓有无松动与其有关技术数据是否相符。启闭机支架与基础布置平面接触面积要达到90%以上，螺杆轴线要垂直于闸台上横梁水平面，并与闸板吊耳中心重合，以免受侧向力螺杆弯曲或闸门受卡损坏机件。
2. The installation method of the hoist is the same as that of the
general machine. Before installation, it is necessary to check whether
the parts of each part are good, or whether the bolt is loosened or not,
and whether it is consistent with the relevant technical data. The
plane contact area of the hoist frame and the base layout should be
above 90%. The axis of the screw should be perpendicular to the
horizontal plane of the upper beam on the gate, and coincide with the
center of the sluice, so as to avoid the bending of the side force screw
or the damage of the lock. It
3, after the installation of the hoist, the test run, first without
load test, let the screw two trips, listen to its abnormal sound, check
whether it meets the technical requirements. Two is to make a load
test. If the new gate must be removed from the transport of the gate and
the fixed part of the assembly process, it should be noticed whether
the gate has the phenomenon of death and deviation. If there should be a
trial operation, the screw will be made two strokes under the rated
load, and the operation of the screw and the gate can be observed, and
there is no abnormal phenomenon. When it is confirmed, it can run
formally. After the load is running for a period of time, it should be
maintained for the first time, and the metal foam produced by the
friction of the new machine parts in the machine, especially the screw,
screw, mother, worm wheel and worm, should be cleaned, coated with
lubricating oil and continued to be used
