In front of us, we have contacted a lot of types of pump, today, Xiaobian introduce a new pump - double-acting pump. Below, Xiaobian through double-acting pump working principle and structural characteristics for everyone to introduce such products. After the introduction and so on, we can compare with the pumping oil pump introduced in the past to see if there is any difference. Double-acting pump working principle and structural features 1, the working principle: the lower part of the fixed valve is opened on the stroke, at the same time, the upper chamber volume decreases, the pressure increases, the fixed valve is closed, the lower valve closed, the upper chamber The oil flow opens the upper flow valve and discharges the ground through the upper plunger. Under the next stroke when the fixed valve is closed, the downstream valve open, the upstream valve closed, the crude oil through the next plunger, the plunger into the tubing. At the same time, the volume of the upper chamber increases, the pressure decreases, the upper fixed valve opens, and crude oil enters the oil sump from the annulus of tubing and casing. 2, the structural features: â‘´ a reciprocating stroke can be completed twice the process of oil absorption and drainage, pump diameter and work parameters exactly the same pump increased liquid production. (2) Because of the downward resistance of the column when the down stroke is larger, it is not appropriate to use it in oil wells where the viscosity of crude oil is too large and serious in sand production, and the sucker rod column is easy to break off. Double-acting pump increased displacement, compared with the same displacement screw pump, the cost is greatly reduced; Compared with the electric submersible pump, the cost and energy consumption have dropped significantly. On the double-acting pump principle and structural characteristics of the introduction, Xiao Bian to say this, from the text we can easily find, double-acting pump has advantages, the cost and energy consumption are relatively low, which for the user to That is undoubtedly a fortune.
