400X Flow Control Valve is uses for its high accuracy pilot operated flow control and is suitable for flow and pressure control of the pipeline to keep the flow preset unchanged, limit an extra-big flow at the preset value and properly lower the high pressure on the upstream, the flow
at the downstream will not be affected by the pressure changing of the main valve at the upstream.

In addition, through the application of self-propelled dual-power electric hydraulic workover rigs and non-compression well blowout preventer devices, the ground environment and underground reservoirs are protected, and the clean production of workover operations is realized, becoming an oilfield green well repair. New model.
Conventional workover work machines have many technical problems, such as large power, low energy utilization, and poor handling performance, which have long constrained the development of workover operations. For this reason, the scientific and technical personnel of the Jinzhou Engineering and Technology Department have independently developed a self-propelled dual-power electric hydraulic workover rig through many years of technological research. The self-propelled double-power electric hydraulic workover rig uses the wellsite industrial power supply as the main power source, and the motor drives the variable displacement pump as the power unit. In a single well operation, the 45-kilowatt motor can be started, and the platform well can start 45 kilowatts with the power supply enabled. And 22 kw two motors to improve ergonomics. Using hydraulic oil as the transmission medium to drive the low-speed high-torque motor to rotate, and then driving the drum through the gearbox to transmit the power to the hoisting system of the workover rig via the wire rope wound on the drum, and to control the electric and hydraulic control system. Next, complete the scheduled work. Taking into account the lack of power at the wellsite and the handling of unexpected accidents, the self-propelled dual-power electric hydraulic workover rig will use the diesel engine of the workover rig's bottom car as a backup power source. Through the shifting transmission system, the constant power variable displacement pump will be driven at a low speed. The torque motor provides power to complete the scheduled work.
The self-propelled double-powered electric hydraulic workover rig has a compact structure, simple installation, good maneuverability, high safety, good adaptability, and environmental protection and energy saving. The whole machine operates stably, and all indexes meet the requirements of the process and operation; due to the use of a pump control system , Electro-hydraulic integration technology, high degree of automation of the whole machine, during operation, the motor, pump, motor always run smoothly, temperature rise is normal; noise and current at startup is small, without any abnormal vibration and noise; brake is light and reliable , smooth; hook maximum lifting speed of 1.25 meters / second, the maximum lifting hook 600,000 cattle.
Liaohe Oilfield independently researches and develops hydraulic workover rigs to reduce costs and increase efficiency
After years of technical breakthroughs by the Jinzhou Engineering and Technology Division of Liaohe Oilfield, the self-developed self-propelled dual-power electric hydraulic workover rig was successfully tested in 2008. Up to now, 3 units have been promoted and applied, and 169 wells have been completed. A production value of 9.5 million yuan, saving fuel costs 250,000 yuan.
