The gas will effect the pump efficiency of deep well-pump, if the amount of the gas of oil well is large, even gas locking occurs.
如果油井产出气量较大，则这些气体对深井泵的泵效将产生很大影响，严重的井甚至发生气锁。
The increased gas volume in the wellbore resulted in frequent gas locking of the ESP, which resulted in little to no liquid flowing past the motor and through the pump.
随着井内气体量增加，进一步造成ESP频繁气锁，最终泵只能举升少量甚至举升不出液体。
Therefore, the self locking type air spring has the function of maintaining the free type gas spring, and can also be locked at any position of the stroke!
所以自锁型气弹簧在保持了自由型气弹簧功能的同时，还可以在行程的任一位置锁定，而且锁定后还可以承载较大的负荷！
In fact, the so-called self locking type gas spring or Angle or is a kind of air spring can be locked in any position of the stroke.
其实所谓的自锁型气弹簧也好调角器也好，都是一种可以在行程任一位置锁定的气弹簧。
The self-locking gas spring is divided into an elastic self-locking and a rigid self-locking according to the different forms of self locking.
自锁型气弹簧根据自锁形式的不同，分为弹性自锁和刚性自锁。
Traction gas spring also has a corresponding free-type, self-locking type.
牵引式气弹簧中也有相应的自由型、自锁型等。
The piston rod self-locking type gas spring end there is a needle valve open the needle valve is self-locking type gas spring can run as the free type gas spring;
自锁型气弹簧是一种可以在行程任一位置锁定的气弹簧。 在自锁型气弹簧的活塞杆端部有一个针阀打开这个针阀，则自锁型气弹簧可以象自由型气弹簧那样运行；
But there are people called: self-locking type pneumatic rod, in fact, lockable gas spring or the so-called Angle or is a kind of air spring can be locked in any position of the stroke.
但是也有人就称之为：自锁型气动杆，其实所谓的自锁型气弹簧也好调角器也好，都是一种可以在行程任一位置锁定的气弹簧。
But there are people called: self-locking type pneumatic rod, in fact, lockable gas spring or the so-called Angle or is a kind of air spring can be locked in any position of the stroke.
但是也有人就称之为：自锁型气动杆，其实所谓的自锁型气弹簧也好调角器也好，都是一种可以在行程任一位置锁定的气弹簧。
