In oil extraction equipment, tubing pump and rod pump are two mainstream types of manual lifting equipment. Although they belong to the same category of oil pumps, there are significant differences in structural design, applicable scenarios and performance. As an enterprise focusing on the research and development of petroleum extraction equipment, Tieling Dongsheng has deeply cultivated the API standard system. The APl rod pump we produce has become the preferred equipment for many oil fields due to its compliance and adaptability.

At present, the development of global oil and gas resources is gradually turning to the field of difficult to recover reserves, of which the proportion of heavy oil resources is increasing year by year. However, complex well conditions such as high temperature, high pressure, and high viscosity have become key bottlenecks restricting the efficient extraction of heavy oil. In this context, thermal recovery sucker rod pump, with its unique technical advantages, has gradually become the core equipment for solving complex well mining problems. Its precise positioning of adapted well conditions provides important support for improving the efficiency of oilfield development.

In the field of heavy oil and high-viscosity crude oil extraction, the performance of thermal recovery sucker rod pump directly determines the recovery efficiency and operating costs of oil fields. As a professional manufacturer in the field of domestic petroleum machinery, Tieling Dongsheng relies on in-depth research on thermal mining conditions to create the thermal recovery sucker rod pump.

In the field of industrial fluid delivery, pumps, as key power equipment, support the operation of multiple industries. According to the basic theory classification of pumps, its core types can be divided into three categories according to the working principle: positive displacement pumps, dynamic pumps and other types of pumps.

The essential difference between downhole pumps and drilling pumps begins with the differentiation of application fields.Drilling pumps are mainly used in clear water extraction scenarios such as agricultural irrigation and industrial water supply.

In the process of oil extraction, the extraction of sand-containing wells has always been a difficult problem in the industry. When sand enters the interior of the oil pump, it will cause wear and tear, plunger stagnation and other failures.

In the field of petroleum extraction equipment, API standards are the core yardstick for measuring product performance. As an enterprise focusing on the research and development of petroleum rod pumps and pipe pumps, Dongsheng Petroleum relies on the API 11AX standard to build API type rod pumps.

API type rod pump strictly follows the API Spec 11AX standard of the American Petroleum Institute, from the size specification of the plunger diameter of 1.0625-3.75 inches to the structural requirements of the X-type thin-walled pump cylinder, there is a clear technical definition. As an API 11AX certified company, Tieling Dongsheng's API type rod pump can be directly connected to the procurement standards of large oil fields such as PetroChina and Sinopec.

In the field of petroleum extraction, the rod pump oil recovery system has become the most widely used manual lifting method due to its high adaptability, simple structure and easy maintenance. As the core equipment of the system, API tubing pump occupies an important position.

Downhole sucker rod pump generally refers to a plunger-type oil pump driven by the reciprocating movement of the sucker rod up and down. It is the key underground equipment of the rod pumping system. It is mainly composed of four parts: pump cylinder, plunger, fixed valve and swimming valve. When working, the ground pumping unit drives the plunger up and down through the pumping rod.
