pallet is one of the latest composite tray. It is mainly by extrusion
WPC profile extrusion machine, and then assembled. It combines wooden pallets, plastic
Feed tray and steel tray advantages abandoned its shortcomings, has the flexibility to produce
? High strength, corrosion-resistant, non-absorbent properties, to solve the wooden pallet cleanliness
? Poor quality testing irregularities and short life problems, not solve the plastic tray
? Temperature difference changes, making the restricted geometry and steel tray easy to rust, easy
Corrosion, since the major and other issues.
90 North China Oilfield a plant small-displacement high-lift pumps show their skills
??? According to the China Petroleum Daily reported that as of December 24, 2009, North China Oilfield an ordinary pump and pipe factory integration advantages of small-displacement pump, oil pump Gao Yang Cheng Qian successfully developed and have been in Yan 9-13, Xiliu 10 flat, geese 10 wells three wells successfully.
Submersible pump function is to downhole pumping liquid into the ground, is an important means of oil yield. Oil a plant tissue and technical staff have worked hard and successfully to solve the well fluid flow rate is too low and other technical difficulties, successfully developed a small displacement, Gao Yang Cheng Qian oil pump, submersible pump used to expand the scope, especially for low-yield wells, inclined , deep wells and eccentric wear serious, check period more than 300 days, the technical indicators in line with national standards, the performance to meet the design requirements.
Small displacement, Gao Yang Cheng Qian oil pump, which can effectively reduce the sucker rod broken off, wear and abrasion caused by the operation tubing, workover costs and tubing, sucker rod losses, reducing the workload for the pump and adjust parameters; and rodless pump, can reduce equipment capital investment, reduce operating and maintenance costs, ease of management, lower production costs, especially for inclined, Hand pallet jacks wells reduce mining costs more effectively.
This small displacement, lifted Cheng Qian oil pump eccentric wear in severe applications geese 9-13 wells, increasing oil 6.9 tons, to the current cumulative oil 1027 tons.
