Hydraulic piston pump in high gas oil ratio, sand, high pour point oil, wax, heavy oil, deep well, inclined well and horizontal well has strong adaptability. Oil production system of hydraulic piston pump: pump system components and types of hydraulic piston is mainly composed of electronic diesel fuel pump a ground power liquid tank, three cylinder high-pressure pump, control manifold, wellhead control valve and the pump. The pump is the core component of the system. The pump is the core component of the system. The downhole hydraulic piston pump with single and double acting two, ground pump with high pressure plunger pump. The process has two kinds: ① open flow. A single tube structure, with low viscosity crude oil as power fluid, can reduce the pipe friction resistance, but also can reduce the extracted oil viscosity, and fuel transfer hand pump the produced liquid mixed together produced the ground. The closed type flow. With oil or water as power fluid, water to add preservatives and lubricants, self circulation is not with the liquid phase output, working process needs only a few additional. Hydraulic piston pump can be single well operation, also can build pump group centralized management, capacity and wide adaptation range, from tens to thousands of cubic meters daily, suitable for deep wells, high lift wells, wells, inclined shaft. Has the advantages hydraulic piston pump of adjustable capacity, lifting pump can not afford the tubing, convenient operation and management. Pump efficiency can reach more than 85%. Disadvantage is the ground to build a high pressure pipeline, dynamic solution to deal with, increase the well construction and management costs.
Pump plays an important role in the petrochemical plant, known as the device heart said gas transfer pump operation is stable and reliable, not only the normal production of the device is very important, the long period operation of equipment, energy saving is also of great petrol dispenser pump significance to ensure the therefore, the steady and safe operation of equipment is one of the main contents of maintenance repair work of the most common fault phenomena of vibration gas transfer pump, analyses and puts forward the way of vibration, in order to further improve the level of maintenance and repair work.With the operation and the fuel transfer hand pump oil circulating gas transfer pump, in return for high vacuum end will re evaporated into steam. Will affect the gas transfer pump, increase the pump oil pollution. Set the gas ballast valve can effectively prevent the condensation of condensable gases, namely the gas transfer pump in the compression process, gas ballast valve through the gas hole of the permanent dry gas mixed with compressed gas, condensable gas partial pressure in the pump when the temperature reaches the saturation vapor pressure, pressure of compressed gas can reach exhaust pressure, exhaust valve is opened, the condensate and dry gas discharged simultaneously.The difference between single-stage and two-stage diesel transfer pump is a two-stage pump can obtain a higher vacuum. In the two-stage pump, when the presence of low-level and high-vacuum chamber vacuum level range, you need to set up catching rabbits auxiliary exhaust valve. When the auxiliary exhaust valve is aimed at higher inlet pressures.
Elevation adjustment is accomplished with an electric washer engaging the external gear pump decrease legs and between the base. Shaft center rib elevation deviation of ± 10mm. Internal gear meshing leveling electric pump centerline to find a good location and elevation, they start to adjust the level of external gear pump inside, first with fine age 0.05mm / m square meter level, in external gear pump measurements performed on front and rear ends of the spigot. Adjust the level, you can add and subtract thin metal meshing between the external gear pump foot and the base unit within the electric adjustment. Level of engagement within external gear pump allowable deviation is generally 0.3-0.5mm / m. Internal gear meshing dispenser fuel pump centerline position, elevation and level of degree to find a good post, you can connect an electric bolt external gear pump and tighten the base, then use a level to check whether there are changes in its level, if no change, you can install the motor. The main job is to mount the motor to the center line of the motor shaft and the centrifugal pump is adjusted to the center line of the shaft in a straight line. Bedroom shaft multistage centrifugal manual fuel transfer pump and the motor are connected together using a variety of coupling, the installation operation of the motor is the main alignment coupling, a specific alignment method will be described in the assembly of the coupling . There must be an axial gap between the motor coupling halves, whose role is to prevent the shifting of the role of horizontal multistage centrifugal parts for pumps shaft spread to the motor shaft or motor shaft axis traverse action spread. Thus, this gap must be of a certain size, generally greater than the amount of play of the shaft and the centrifugal pump and the motor shaft. Typically this gap has specified on the drawings, as the paper is no such requirement, can be adjusted with reference to the following figures: Small centrifugal pumps for 2-4mm; medium-sized centrifugal pump for 4-5mm; large centrifugal pumps for 4-8mm.
Hydraulic piston pump is a hydraulic drive rodless pumping equipment, which is powered from the ground by the pump tubing or a dedicated channel power fluid pumped downhole pressurized after driving motor up and down reciprocating motion, will spread to the underground high-voltage power fluid drive cylinder and valve, to help downhole pumping piston. Hydraulic piston pump for high gas-oil ratio, sand, high pour point oil, wax, oil tank monitoring system, deep, deviated and horizontal wells has strong adaptability. Hydraulic piston pump oil system components and types: hydraulic piston pump Fuel management systems consists of ground power tank, high pressure triplex pumps, control manifold, wellhead control valves and downhole pump. Downhole pump is the core component of the system. Downhole pump hydraulic piston pump with a single and double acting two kinds of ground with high-pressure piston hydraulic piston pump. There are two processes: ① open process. Single-tube structure, with low viscosity oil for power fluid, the pipeline will reduce friction, but also reduce the viscosity of the oil extracted and mixed with the produced fluid taken out of the ground. ② closed processes. With a light oil or water as the power fluid, lubricants and preservatives to be added when water is not mixed with the liquid circulating their own output.
Gas transfer pump fuel at normal pressure is delivered from the tank to the carburetor (gasoline engine) or a high-pressure pump (diesel) important components, plug and petrol dispenser pump out the oil from one-way valve. When the plunger down, the passage-way valve is closed, the one-way valve opens into the passage, the fuel into the pump chamber. When the parts for pumps is stuffed with rows into the oil-way valve is closed, the oil line check valve opens, total fuel to the engine combustion fuel monitoring system. No car in this part, only the gas transfer pump, also known as gas transfer pump, before the old car will have a car pump, fuel pump if it is asked if it is driven by direct current, plus post after inhaling fuel pressurization, after the oil engine fuel delivery. It works, work the same way and submersible pumps.
