1. Overview

Oil-well pump hydraulic disassembly and assembly machine is applicable to fabricate and repairing the tools, tubings, casings and other threaded stays under oil-wells. The whole machine consists of two parts.

1) The host is made up of master tongs, back tongs, two tubings frame, a platform, a hydraulic system, a fuel tank, a radiator. Master tongs and back tongs are epicyclic gear and epicyclic claw four point chucking structure. It can hold random external diameter workpiece in the application, no flip over. The advantage of this structure is flexible in action, safe and reliable, high-efficient. It is used in national major oil fields widely. Because the machine can be operated by only one person, it increases working efficiency and reduces the cost of production. According to the actual difierent length of the tubes, back tongs whose speed can be self-operated control are shuttled in the slideway.

2) The platform is composed of electric appliance elements, and the safe voltage is 24-volt DC(There is a hydraulic directional control valve in Hand-Over-System. According to the needs of users,we can install torque displayer PLCand IPC).
