Problems solved by technology
[0003] At present, the plungers used in the field are usually made of alloy steel. The main ones are chrome-plated plungers and carburized and quenched plungers. These plungers have poor wear resistance and are easily corroded in high-temperature and high-pressure working environments. The service life is short, and the sealing packing needs to be frequently adjusted and replaced during use, which seriously affects the work efficiency, increases the labor intensity and time of workers, and brings many hidden dangers to safe production.
Moreover, due to the short life of the plunger, it needs to be replaced frequently. However, it is a very troublesome thing to replace the plunger once. After the shutdown, the oil pump and the plunger at a depth of one or two kilometers must be hoisted to the ground for cleaning and replacement, which costs a lot of money. A large amount of manpower, while oil recovery efficiency is greatly reduced

The invention discloses a ceramic plunger for a pump. The ceramic plunger comprises a plunger shell, a plunger core arranged inside the plunger shell to be in extensible motion, a plunger connecting rod and a gland, the gland presses at one end of the plunger core, the plunger connecting rod sleeves on the plunger core, and the plunger core and the plunger connecting rod are matched with each other through ratchets and fixed and limited through the gland on the end portion of the plunger core. By the above mode, resistance to high pressure, corrosion resistance and wear resistance of the plunger can be improved, service life of the plunger can be prolonged, production efficiency can be improved, and the ceramic plunger is firm in connection and easy to maintain and replace.
Description
technical field [0001] The invention relates to the field of plunger pumps, in particular to a ceramic plunger for pumps. Background technique [0002] In the oil field production system, the high pressure plunger pump is one of the main equipment. In the high-pressure pump, the plunger is the key component and the main wearing part. Therefore, the performance of the plunger is often directly related to the performance and working efficiency of the high-pressure pump. [0003] At present, the plungers used in the field are usually made of alloy steel. The main ones are chrome-plated plungers and carburized and quenched plungers. These plungers have poor wear resistance and are easily corroded in high-temperature and high-pressure working environments. The service life is short, and frequent adjustment and compression and replacement of sealing packing are required during use, which seriously affects work efficiency, increases labor intensity and time of workers, and brings...
