Hydraulic piston pumps or solids pumps, hydraulic power pack driven by hydraulic cylinders, hydraulic

cylinders advance delivery cylinder, the cylinder will transport material output to the pipeline. Generally divided into single-and dual-piston plunger pump are positive displacement vacume pump, especially for high solid content, viscous material long-distance pipelines, the advantage is running very stable and reliable, but the larger noise. Widely used in sewage treatment, solid waste management, mining and metallurgy, dredging, dredging, petrochemical, power plants, cement industry and other fields. Piston has several decades of history, its popularity depends on two main reasons: one, they do not require external energy - the water's force to provide them with the necessary energy. 2, an apparatus which is extremely simple, only two moving parts. The basic principle is simple piston pump. Momentum This vane type pump uses a relatively large movement of water to the relatively small volume of water pumped upward. To use the plunger, there must be located above the water pump. For example, on the mountainside have a pond, so that you can install the pump in the pond below. The water from the pond with water pipes toward the pump. Pumps have a valve, this valve and allow water to flow through the pipes to accelerate.

Hydraulic piston pump


Work process just to make a small amount of supplement. Hydraulic piston pump can be operated single-well, you can also build gear type pump centralized management, a wide range of displacement adaptation, from tens to thousands of cubic meters per day, etc., suitable for deep, high-lift wells, heavy oil, inclined. The advantage is the displacement can be adjusted, from the convenience of parts for pumps tubing can not afford the operation and management. Pump efficiency up to 85%. The disadvantage is that the ground have to build a high-pressure pipelines, power fluid to be processed, an increase of well construction and management costs.

electric gear pump

Electric gear pump body base mounted motor. Because fuel dispensing pump body weight than the motor, but it and other equipment for the pipeline connected to each other, while other equipment after installation, electric gear 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 diesel transfer 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.

Hydraulic piston pump additional features completed by the safety valve and check valve

Hydraulic piston pump additional features completed by the safety valve and check valve. When the pressure relief valve to avoid excessive increases fuel line blockage, caused by pipeline rupture or hydraulic piston pump damage occurred. The purpose of the one-way valve is set, when the fuel pump to stop working in the oil seal, so that the fuel system to maintain a certain residual pressure to the engine easier to start the next. Hydraulic piston pump is the main pump oil can be divided according electric petrol pump to their different structures and flat roller blade. The most common roller hydraulic piston pump. Hydraulic piston pump is installed in the vehicle fuel tank mounted on the outside and the fuel tank outside. There are a few models in the fuel tank, outside of the installation of an hydraulic piston pump, both series in oil on the road.In modern cars used in a variety of fuel injection system, fuel supply means they are different, but must be safe with an hydraulic piston pump. Its main task is to supply enough fuel system and there is a certain pressure fuel. Due to the mechanical petrol dispenser pump diaphragm by structural constraints, installation location away from heat both fixed-line and also can not be tapped installed. The hydraulic piston pump location can be arbitrarily chosen, and have no air resistance characteristics.

Gas transfer pump is how to transport fuel

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.

Gas transfer pump and adjustment of the pump body

Measurement and adjustment of the pump include alignment, looking for elevation and leveling three areas.
(1) vertical alignment is to find the gear meshing being, the horizontal centerline. Longitudinal diesel fuel dispenser centerline of the gear meshing is based on the shaft centerline prevail; transverse centerline to gas transfer pump centerline of the outlet pipe shall prevail. Looking positive, according to the mounted device centerline (or base and wall studs centerline) to be measured and adjusted so that the longitudinal internal gear meshing, and cross the center line to gas transfer pump meet the requirements of mobile fuel dispenser drawings and is well connected with other devices. Internal gear meshing , the horizontal centerline dimensions by drawing tolerances within ± 5mm range. Is the shaft centerline elevation (2) to find the elevation of the pump prevail. Generally used to measure the water level when mechanical fuel dispenser looking for elevation. When gas transfer pump 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.

What is the difference between the internal gear pump and external gear pump

Internal external gear pump design, decided to pump function: transportation, small differential pressure, the outlet pressure is not high. It can also convey high viscosity fluid at high speed. The external external gear pump is divided into two kinds: one kind is high speed, for example: hydraulic external gear pump at a low speed, for example: gear measurement electric petrol pump gear metering pump, the meshing used for metering, high pressure, the maximum output of 175KG, or even higher. The transfer of high viscosity fluid. Internal gear is a gear and he have the same modulus, tooth inner gear ring thickness consistent with operation. The meshing is two or more than two of the same modulus, tooth ordinary gear running thick consistent (with straight tooth, helical, herringbone gear etc.). External gear pump drive gear and the driven gear type pump gear steering instead, simple structure, light weight, convenient maintenance, long service life; internal external gear pump drive gear and the driven gear to the same, more complex structure, processing is difficult, small flow pulsation.
