Special intelligent motive power device of oil pumping unit

Abstract

The invention relates to a special intelligent motive power device of an oil pumping unit. The oil pumping unit is driven by an output belt pulley with the variable diameter, the output belt pulley with the variable diameter is connected with a speed reducer with the fixed transmission ratio, the speed reducer with the fixed transmission ratio is connected with a multi-gear shifting speed changer, the motive power output end of an oil and gas dual purpose engine is connected with the multi-gear shifting speed changer, the oil and gas dual purpose engine is connected with a control cabinet through a cable, and the control cabinet is connected with a computer through GPRS. The invention can be widely used for the motive power of the oil pumping unit used for the coal bed or natural gas pumping extraction operation, the huge investment of the high-voltage and low-voltage electric network is saved, the electric consumption of the operation of the oil pumping unit is avoided, and the effects of energy saving and exhaust reduction are reached. The invention has wide speed regulation ratio range, can realize remote stepless speed regulation and remote starting and stopping, can reduce the manual perambulation cost, and is favorable for the centralized monitoring of the mass operation of the oil pumping unit.

Description

technical field [0001] The invention relates to a new type of intelligent power device for pumping units, which is capable of stepless speed regulation, wide speed regulation ratio, energy saving and intelligent. Background technique [0002] The existing coalbed methane or natural gas pumping units are mainly powered by various speed-regulated motors. Since the operating sites of the pumping units are widely scattered in remote areas, the power required by the motor work must be transmitted through the newly designed and laid power grid. There are shortcomings such as large one-time investment in transmission and distribution lines and long payback period; at the same time, due to the on-load start-up, the actual configuration of the motor capacity of the speed regulating motor is too large, the speed regulation range is narrow, and the electric energy used by the pumping unit is too high. Defects such as high consumption, high operating costs, and difficulty in remote moni...

[0002] The existing coalbed methane or natural gas pumping units are mainly powered by various speed-regulating motors. Since the operating locations of the pumping units are widely scattered in remote areas, the power required for the motor work must be transmitted through the newly designed and laid power grid. There are shortcomings of large one-time investment in transmission and distribution lines and long payback period; at the same time, due to on-load start-up, the actually configured motor capacity of the speed-regulating motor is too large, the speed-regulating range is narrow, and the power consumption of the pumping unit is too high. Disadvantages such as high consumption, high operating costs, and difficulty in remote monitoring

[0003] In recent years, coalbed methane or natural gas pumping units have also used gas engines as power. However, the function and means of speed regulation of pumping units are simple, and only rely on the speed of the engine to adjust on site. The speed regulation range is narrow and cannot Realize the function of remote speed regulation
