This is a light top driving force designed for domestic users according to years of foreign experience and users.
The top drive has four following functions:
1. Dynamic seal of wellhead rotation
2, support rod, and well fluid loading
3. Safe release of reversal energy when shutdown
4. Provide a method of driving (provide a method of rotating the pump)
Based on these four functions, we embody the following intentions in our design objectives:
1, to provide an economic pump transfer method
2. Safe support for the axial load of the pump transport system
3. Safety to mediate the energy consumption during braking
4. Provide a durable and effective dynamic seal |
