Progressive Cavity Pump with LBQZ Surface Drive Head
**Progressive Cavity Pump System – Brief Introduction**
The progressive cavity pump system includes a surface drive device, downhole screw pump, electrical control panel, and matching tools. This system is widely used in oil fields both domestically and internationally, playing a crucial role in oil production. It is increasingly being adopted to replace traditional heavy pumping units in shallow and medium-deep wells due to its efficiency and reliability.
**Applicable Oil Conditions**
This pump is suitable for low-viscosity crude oil as well as heavy oil, high-paraffin oil, high-wax oil, high-sand oil, and high-gas oil. It offers advantages such as low initial investment, high oil production efficiency, low energy consumption, simple structure, and ease of operation, installation, and maintenance.
**Key Advantages**
- Low capital investment
- High oil production efficiency
- Energy-efficient operation
- Simple and durable design
- Easy to install and maintain

1. Turn off the hydraulic system: Before replacing the hydraulic cylinder, it is necessary to turn off the system to avoid liquid leakage in the hydraulic system.
2. Disassembling the hydraulic cylinder: Disassembling the hydraulic cylinder requires the use of tools such as wrenches, screwdrivers, etc. Firstly, the hydraulic pipeline needs to be removed, and then the bolts of the hydraulic cylinder need to be removed to remove the hydraulic cylinder from the machine.
3. Check the hydraulic cylinder: Check if there is any damage to the hydraulic cylinder, and if there is any damage, replace it.
4. Install a new hydraulic cylinder: Install the new hydraulic cylinder onto the machine and secure the cylinder with bolts.
5. Connect hydraulic pipeline: Connect the hydraulic pipeline to the hydraulic cylinder, pay attention to the position and direction of the connection, and ensure that the connection is secure.
6. Test system: after replacing the hydraulic cylinder, it is necessary to test whether the system operates normally, check whether the hydraulic cylinder operates normally, and deal with any problem in time.
7. Cleaning work: Clean the liquid and debris in the hydraulic system to ensure that the system is clean and avoid any impact on the system.
