Brief introduction of hydraulic plugging and profile control pump
Hydraulic water shutoff and profile control pump is widely used in the field of construction machinery because of its unique advantages and working characteristics. It is the working principle of the high speed rotating machinery motor through constant power pump into the hydraulic oil pressure to the hydraulic cylinder by the pressure energy of the hydraulic oil through the piston directly into the working fluid pressure, and thus change the traditional mechanical transmission process, reduce transmission links, make energy transfer high efficiency.
At present, the traditional mechanical three cylinder single acting pump is widely used, but their common drawback is the large size, vulnerable parts life is short, piston and cylinder life is only about 10Ch and 200H, and some even shorter. This not only greatly improves the cost of the injection equipment, but also seriously hinders and restricts the continuous injection of the plugging agent, and reduces the oil production effect of the new oil recovery technology.
The characteristics of constant power variable pump determine that the displacement of the pump decreases with the increase of the layer pressure, which is very suitable for water plugging and profile control. Field test shows that TDB hydraulic water shutoff profile control pump has stable operation and small vibration. Especially in the middle and late stage of high water cut reservoir, water plugging, profile control and various plugging and flooding three times of oil recovery technology have been widely adopted. The injection equipment necessary for these processes, the amount of high-pressure injection pump is greatly increased.
The main technical parameters of TDB hydraulic pump for water shutoff for maximum working pressure 25MPa 12m3/ h a maximum displacement of 10 ~18min, motor power 55kW, main structure and working principle of the quality 5t. TDB hydraulic pump for water shutoff by hydraulic control system, reciprocating pump, cooling system and the bottom seat and other parts.
That scene features and technical parameters of the test and application of TDB hydraulic pump, blocking performance of profile control and water pump is superior, reliable work, and the general mechanical field is three cylinder single action pump test has the following characteristics: strong self-priming capacity, no perfusion pump can work normally; the vulnerability of long life, the fluid end of piston the cylinder, valve and valve seat, the service life is 10~20 times of the mechanical type three cylinder single acting piston pump; the working line of low speed, low rate of shear plugging, plugging agent does not destroy the performance of water shutoff and polymer injection well.
It adopts hydraulic transmission principle of high speed rotating machinery motor through the constant power pump is converted into pressure energy of the hydraulic oil, the hydraulic cylinder hydraulic oil pressure can be directly converted into working fluid through the piston pressure: TDB hydraulic pump for water shutoff and this changed the traditional mechanical transmission chain, reduce the transmission links, realize the transfer of energy efficiency. The characteristics of constant power variable pump =2300, oil filter to the hose, it can be seen that the above flow types are turbulent.
Hydraulic pump is one of the power components of machinery and equipment, and has the same important position as the engine, not only should be carefully selected, but also should pay attention to the reasonable maintenance and repair in the process of use. The construction machinery house is equipped with various types and brands of hydraulic pump components and components. Welcome to call manager Zhang: 13705210834.
