Hydraulic piston pump is developed rapidly in recent years

This paper introduces the structural characteristics and working principle of a new type of hydraulic piston pump, diesel pump manufacturers and the performance parameters of this kind of pump is also introduced. Production practice of the type hydraulic piston pump by the Shenyang oil recovery of high pour point oil, compared with using conventional hydraulic piston pump cycle, period of changing the pump is extended from 1 months to 9 months, can save the pump inspection costs more than 1 yuan.
Hydraulic piston pump is developed rapidly in recent years a rodless oil pumping equipment.It depends on the hydraulic transmission energy, pumping crude oil to the ground from the well.It can rely on the hydraulic up, adapt to the high wax oil, high pour point oil in deep well, deep well and complex well conditions. The Shenyang oil field has since the end of 1986 formally put into development, mechanical fuel level gauge ,in order to meet the need of high pour point oil mining, hydraulic piston pump as a recovery of high pour point oil reservoir.

Single chamber piezoelectric gas transfer pump design

The simulation results show that: the first-order natural frequency below the valve in the pump working frequency, fuel card management system and when the critical pressure acting on the valve on both sides of the value is greater than 0.8 kPa when the valve opening height, because is too large to be restored to
the closed pump due to job failure.
For the manufacture of gas output performance good piezoelectric pump, designed a kind of umbrella shaped rubber valve model. Analyzed the flow characteristic umbrella shaped rubber valve, and using Ansys software, simulation analysis on performance of the valve,automated fuel management system to determine the critical pressure umbrella shaped rubber valve of the first 10 order natural frequency and valve failure effect in the valve on both sides of the value.

Hydraulic piston pump surface gathering process

The hydraulic piston pump oil recovery system can be divided into two types of open cycle and closed cycle by power liquid circulation.
In Open Systems (OPF), fluid power and recovery liquid mixing together back out of the ground, fuel pump dispenser in a closed system (CPF), ground and downhole fluid circulates in a closed loop, and pick out feed. Open type hydraulic piston pump system closed hydraulic piston pump oil production system ground transportation process open power fluid system of surface gathering process, the process is more suitable for multi well system, under the jurisdiction of the numbers, dozens of wells.
Simple and economic are the main features of the open process. Of course, in the open system, water or other liquid is used as the power fluid, but due to the addition of chemical additives, portable fuel transfer pump lubricating, anti rot, deoxygenation) to produced liquid mixing produced generally has been lost. Therefore must be continuously added.

Electric gear pump body base mounted motor

Electric gear pump body base mounted motor. Because the pump body weight than the motor, but it and other equipment for the pipeline connected to each other, while other equipment after installation, gas fuel pump body position can be determined, and the position of the motor can be adjusted according to the electric gear pump body position. Hoisting installation steps electric gear pump body electric gear pump body, pump available for small, people raised on its pedestal. For medium-sized pump, can use hauling frame and rollers rolling on the inclined plane to transport and install. For medium and petrol dispenser pump, can use the rafter gantry hoisting, sometimes using a single wooden derrick and the other pulley group together for lifting. In addition, can also use the workshop or basis over the original hoisting machinery (such as bridge cranes, electric hoist, lifting pump) will be directly to the foundation. Hoisting slings, should be bound in the lower electric internal meshing gear pump body, shall not be binding on a shaft or bearing.

Head liquid delivery device

According to the process, drainage requirements, from five aspects to consider the amount of liquid delivery device head, fluid properties, piping layout and operating operating conditions;
Flow is selected barrel cng pump head is another important performance data for key performance players move one data device system manual fuel transfer pump required, the general use of amplified 5% -10% margin lift for selection;
Fluid properties, including liquid media name, physical properties, chemical properties and other properties;
Piping layout condition barrel pump device system refers to the highly liquid feeding liquid feed liquid feed to the distance to the system head NPSH calculations and checking

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, deep, deviated and horizontal wells has strong adaptability. Hydraulic piston pump oil tank monitoring system components and types: hydraulic piston pump system 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 pumps. 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 hydraulic piston pump circulating their own output.

Notes gas transfer pump

Because not fully preheated, will pump in around uneven thermal expansion, so that static seal fuel transfer hand pump leakage points. Such as export, import flanges, pump large cap flange, balance pipe leak, fire or even cause serious accidents, explosions and so on. Heat pumps should pay attention to what Preheat: Preheat the process to correct. The general process is: the petrol dispenser pump outlet pipe entrance across the line pump pre hotline pump inlet. Preheat valve can not open too large to prevent the pump reverse. Preheat the pump speed is not too fast in general, should be less than 50 ℃ / h. Under special circumstances by the portable fuel transfer pump steam, hot water and other measures to speed up the warm-up speed. When the warm-up of 30 to 40 minutes should drive the car 180 °, in order to avoid uneven heating and bending the shaft up and down every.

Measurement and adjustment of the pump include alignment

Measurement and adjustment of the pump include alignment, looking for elevation and leveling three areas.(1) vertical alignment is to find the positive engagement of the gear pump is electric, horizontal centerline. Longitudinal centerline of the gear meshing electric external gear pump is based on the shaft centerline prevail; transverse centerline to centerline of the outlet pipe shall prevail. When in alignment, the mounted device according to the center line (or center line of the stud and base) to be measured and adjusted so that the longitudinal engagement of the manual fuel transfer pump motor, and meet the requirements of the drawing of the transverse center line, and with well connected to other devices. Internal gear meshing vertical electric pump, the horizontal centerline by drawing dimension tolerances within ± 5mm range.Is the shaft centerline elevation (2) to find the elevation of the petrol dispenser pump prevail. Generally used to measure the water level when looking for elevation. When measuring, the benchmark reference point on the plant settings, measured water level of the mounted height, and then moved to the journal benchmark, measure the distance from the shaft surface mounted to, and then the pump can be calculated according to the formula shaft centerline elevation.
