The main technical parameters: the input speed of the car is controllable within the range of 10~200r/min; the output speed is 1~20r/min; the output torque is 1900Mm; the chassis adopts four-wheel trailer type, the wheelbase is 3.2m, the track is 2.3m. : DLC-1 cable drum trailer has a chassis, roller bracket, hydraulic oil motor, reducer, hydraulic operating control valve and pipeline, roller brake mechanism, leveling hydraulic jack legs and so on. First, hoist the new cable or repair cable to one of the roller brackets in the workshop, drag it to the job well site with a tractor, connect the hydraulic oil pipeline of the oil motor to the hydraulic oil pump of the workover rig, and operate the six-way valve. Adjust the vehicle to a horizontal position, and at the same time, fix the vehicle with a ground anchor. When lifting the old cable, the hydraulic power oil is switched to the empty drum drive oil motor through the reversing valve; when the new cable is lowered, the reversing valve is switched to the drum drive motor with the new cable; the rotation speed of the drum is controlled by the hydraulic pressure The opening of the valve is operated to control the braking of the drum by the brake mechanism. According to the calculation of 116 electric pump wells operated in 2002, the annual transportation and lifting costs were 66,800 yuan, and the annual labor saving cost was 143,800 yuan. The installation cost of the device was 45,600 yuan, and the service life was 8-10 years. Maintenance costs are 8,900 yuan. The use of DLC-1 cable drum trailer eliminates the hidden dangers during the construction of electric pump wells, reduces the cost of vehicle use, improves work efficiency, reduces labor intensity, and reduces the quality of engineering caused by cable damage. Rework. (Finish) Hydraulic Support System Seals
The seal of the Saifu lever hydraulic support is composed of a sealing ring, a retaining ring, a guide ring and a dustproof ring.

Hydraulic support seal
Prevent leaks. Used in the category of hydraulic supports: drum ring, composite seal, mountain ring, bud ring, O-ring, etc. Generally rubber, polyurethane material.
Used together with the sealing ring, it has the functions of anti-crowding, guiding and reducing wear. It is generally made of phenolic XII cloth, 45% copper powder mixed with filled PTFE and other materials.
Guide ring:
It is a part used on the jack piston or piston rod to support the movement of the piston or piston rod. It can prevent the piston or piston rod from direct contact and friction with the cylinder during the movement, and protect the cylinder and the piston or piston. The rod is not damaged. Generally, it is polyoxymethylene, polytetrafluoroethylene and other materials.
Dust-proof ring: the main function is to go out and reciprocate the piston rod to expose the impurities attached to the outer surface of the cylinder, so as to prevent impurities such as external dust from entering the inside of the sealing mechanism. Generally rubber, polyurethane and other materials.
