The Jianghe Oilfield of Henan Oilfield has recently developed a new energy-saving and deceleration device for pumping units, which can save more than 1 million yuan in annual cost.
The mine is responsible for the production of more than 1,000 oil and water wells, of which the number of wells with insufficient liquid supply accounts for 1/4. The mine passed the technical research and adopted the pure mechanical transmission theory design. A deceleration device was installed between the pumping unit motor and the reduction gear box. By increasing the transmission ratio, the second deceleration was smoothly realized, thereby reducing the running speed of the large pulley of the pumping unit. Realize the low-rush operation of the pumping unit.

Cone Crusher

Symons cone crusher, also called hydraulic cone crusher, compound cone crusher, is widely used for the metallurgical industry, construction material industry, road building industry,
chemical industry and silicate industry etc. It can be used as secondary, tertiary or quaternary crushing.can crush materials of above medium hardness, such as iron ores, copper ores, limestone, quartz, granite, gritstone, etc. The paryicle size is even and using this symons crusher decreases the circulating, and using multi-cylinder hydraulic clearing system can decrease downtime and save the working strength.
