Problems solved by technology

We found that the existing diesel engine drives have the following disadvantages: 1. The efficiency is very low, and the fuel consumption cost is very high; 2. The speed regulation range is small, and the general speed regulation ratio is within the range of 1:8; The torque at the rotating speed is much lower, which is not in line with the requirement of large torque when the hook load is lifted in actual work! 4. In addition to the main transmission box, an expensive transfer box and torque converter with split gears are required to solve the problem of high torque during heavy load and fast rope speed during normal work.

Embodiment 1

[0024] Such as figure 1 As shown, a workover rig energy storage type electric control drive system, the system includes a permanent magnet motor, a permanent magnet motor controller assembly, an energy storage assembly, and the permanent magnet motor controller assembly is respectively connected to the permanent magnet motor and the storage capable components. The permanent magnet motor includes a permanent magnet motor 7, the permanent magnet motor 7 is a rare earth permanent magnet motor, and adopts a double three-phase winding structure with a phase angle of staggered by 30°. When the permanent magnet motor controller component adopts a speed regulation control scheme with a position signal, The permanent magnet motor 7 needs to be installed with a position signal encoder or a position signal sensor, and the permanent magnet motor can be started without a brush and run synchronously.

[0025] The permanent magnet motor controller component is mainly composed of circuit bre...

Abstract

The invention relates to an energy storage type electric control driving system of a workover rig, which comprises a permanent-magnet machine, a permanent-magnet machine controller assembly and an energy storage assembly, wherein the permanent-magnet machine controller assembly is connected with the permanent-magnet machine and the energy storage assembly respectively. Compared with the prior art,the energy storage type electric control driving system of the workover rig has the characteristics of high dynamic efficiency of the workover rig, high mechanical transmission efficiency, small volume, light weight, steel material conservation, low cost and the like.

Description

technical field [0001] The invention relates to a power drive system of an oil field workover rig, in particular to an energy storage type electric control drive system for a workover rig. Background technique [0002] Diesel engine as the power drive of workover rig is a mature technology and has been used in field for decades. We found that the existing diesel engine drives have the following disadvantages: 1. The efficiency is very low, and the fuel consumption cost is very high; 2. The speed regulation range is small, and the general speed regulation ratio is within the range of 1:8; The torque at the rotating speed is much lower, which is not in line with the requirement of large torque when the hook load is lifted in actual work! 4. In addition to the main transmission case, an expensive transfer case and a torque converter that can be divided into gears will be equipped to solve the problem of high torque during heavy load and fast rope speed during routine work. C...
