Oil pipe line.
Beneficial effects of the present invention.
1st, present invention is generally directed to high-pressure diaphragm pump oil cylinder, piston and sealing ring are cooled down.In actual application,
The body of rod of fluid Jing piston rods is ejected into inner surface of cylinder liner and need to cool down place, and cooling oil not only plays sufficiently cool work to impact point
With, and cooling effect is also played to piston rod in fluid flow process.According to run-in test after membrane pump assembling（Continuously
Operating 8 hours）15～20 DEG C of temperature at cylinder sleeve are measured, and does not use temperature at the cylinder sleeve of the present invention to be 27～35 DEG C, can be abundant
Meet equipment service requirement.
2nd, it is of the invention in assembling process, due to the special construction feature of clip, nozzle and the body of rod, it is not necessary to consider runner
To medium detailed problem, assembly difficulty and machining accuracy is greatly lowered, reduces production cost, improve production efficiency, also, day
Often safeguard and patrol and examine all simple and clear.
3rd, the present invention is with strong applicability, is applicable not only to the industry devices such as aluminium oxide, mine, and in multirows such as Coal Chemical Industries
Industry project equipment has certain promotion value.From the point of view of membrane pump itself design, the bigger barrier film of the parameter such as pressure, stroke
Pump.Practicality of the present invention is stronger.
