摘要：为降减小“高压回流”引起的流量脉动和压力脉动，基于双作用叶片泵的三角减振槽、根据双作用叶片泵的预升压变化过程，设计了一种具有更大通流截面，过渡更加平滑的复合型减振槽。利用PumpLinx软件进行数值模拟，分别监测三角减振槽及复合型减振槽所在的双作用叶片泵流场的出口流量变化和压力变化情况。研究结果表明：当转速在4500~6000 r/min变化时，复合型减振槽比三角减振槽能使出口流量脉动系数分别降低67.6%和67.04%，证明复合型减振槽对降低泵的出口流量脉动和压力脉动的有效性，为双作用叶片泵的结构优化提供一种新的思路。

Abstract: In order to reduce the flow pulsation and pressure pulsation caused by “high pressure backflow”, based on the triangular vibration damping groove of the double-acting vane pump, and according to the pre-boost pressure change process of the double-acting vane pump, a larger flow cross-section is designed. Smoother compound damping grooves. Using PumpLinx software to carry out numerical simulation, the outlet flow changes and pressure changes of the flow field of the double-acting vane pump where the triangular damping groove and the compound damping groove are located are respectively monitored. The research results show that when the rotational speed varies from 4500 to 6000 r/min, the composite damping groove can reduce the outlet flow pulsation coefficient by 67.6% and 67.04% respectively compared with the triangular damping groove, which proves that the composite damping groove can reduce the outlet flow of the pump. The effectiveness of pulsation and pressure pulsation provides a new idea for the structural optimization of double-acting vane pumps.

摘要：新型工程柱塞泵泵盖铸件的结构特殊，由于泵盖内部有细长且交错的油道，其次泵盖铸件材料为球墨铸铁，因此铸件浇注时内部容易出现油道砂芯断裂、砂芯变形、缩松和气孔缺陷，铸造工艺上保证内部空腔残留铸砂的清洁也是难点。由于此类泵盖较为少见，基于对泵盖的结构进行铸造工艺可行性分析和工艺方案设计，预先进行铸造方案的虚拟仿真验证，确定最终工艺方案后进行浇注试制，首次浇注验证泵盖合格，客户加工装试满足工况条件，成功研制出新型柱塞泵泵盖铸件。

Casting Technology and Development of New Type Piston Pump Cover

ZHAO Ying-lie

（Taiyuan Heavy Machinery Group Yuci Hydraulic Industry Co., Ltd., Jinzhong030600, China）

Abstract: The new type of engineering piston pump cover casting has special structure. As there are long and thin oil passage branches inside the pump cover, the internal structure of the pump cover casting is similar to the hydraulic valve body, and the material of the pump cover casting is nodular cast iron, so the internal oil passage is prone to fracture, deformation, shrinkage and porosity, at the same time, it is difficult to clean the residual casting sand in the internal cavity. As such pump covers are rare, based on the feasibility analysis of the casting process and the design of the process scheme for the structure of the pump cover, the virtual simulation verification of the casting scheme is carried out in advance. After the final process is determined, the mold is made for pouring. The first pouring verifies that the pump cover is qualified, and the customer's processing and assembly meet the working conditions. A new type of piston pump cover casting is successfully developed.

摘要：为了获得油气混输泵的两相分离规律以及该分离性质对该泵产生的影响，通过对含气率GVF=0.4的螺旋轴流式油气混输泵进行模拟计算，定量地分析了叶轮域内气液两相的分布及速度变化情况。结果发现：气液分离对流体流动造成的堵塞作用主要集中在靠近工作面以及背面的流道上，对中间流道上的影响较低。对导叶内部流场进行分析，发现两相分离造成的气团堆积，使得进入导叶的流体在流动中存在一低压区，该低压区使得流体在导叶内部形成二次回流。这说明了气液分离现象不但对泵叶轮区域造成了流动堵塞，且造成了导叶的二次回流损失。

Abstract: In order to obtain the two-phase separation law of oil-gas pump and the effect of the separation property on the pump, a helical axial-flow oil-gas pump is numerically calculated when its gas volume fraction GVF=0.4. The distribution in the phase of gas and liquid and the velocity variation in impeller domain are analyzed quantitatively. The results showed as follows: the blocking effect of gas-liquid separation on fluid flow is mainly concentrated on the flow passage near the working face and the back, and has a low impact on the middle flow channel. The internal flow field of guide vane is analyzed. The flow field inside the guide vane of the pump was analyzed. It was found that the air mass accumulation caused by two-phase separation resulted in a low pressure are. The low pressure area causes the fluid to form a secondary reflux inside the guide vane. This shows that the gas-liquid separation phenomenon not only causes flow blockage in the impeller region of the pump, but also causes secondary reflux loss of the guide vane.

Screw-driven Sliding Sleeve Type Low Frequency Pulse Layered Water Injection Tool

（School of Petroleum Engineering, Yangtze University, Wuhan430000, China）

Abstract: Continuous separate layer water injection is one of the most important technologies to enhance oil recovery, but there are some problems such as low water injection energy utilization ratio, low swept volume and so on. A method of pulse water injection technology is proposed, and a matching screw-driven sliding sleeve type low frequency pulse layered water injection tool is designed. The tool is driven by a screw, and the pulse pressure is modulated by the axial reciprocating motion of the sliding sleeve, the pulsed fluid is injected into the reservoir through the inner and outer perforations on the sliding sleeve and the tool housing, which produces continuous high amplitude and low frequency pulsating disturbance to the formation and improves the water injection efficiency. At the same time, the Newton's laws of motion is used to describe the sliding sleeve movement, the finite element analysis is carried out with Abaqus to verify the rationality of the tool structure. The results of finite element simulation show that the sliding sleeve can adapt to the working condition of 25MPa water injection, and has the working ability of downhole. Under the dynamic load of 20~25MPa, the maximum Mises stress and the maximum displacement of the sliding sleeve are greater than 20MPa, when the load is less than 25 MPa and the load is 39 MPa, the sliding sleeve will have plastic deformation. The results show that the new sliding sleeve type low frequency pulse layered water injection tool solves the problems of high intensity and fast attenuation of pulse wave in the process of transmitting along the pipe string, it is helpful to maintain the suitable interlayer pressure difference under the complex wellbore structure, and can provide technical guidance for the design of layered water injection tool.
