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, electric gear pump body position can be determined, and the position gas transfer pumpof 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 external gear pump pedestal. For medium-sized pump, can use hauling frame and rollers rolling on the inclined plane to transport and install. For medium and large 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 hydraulic piston pump 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.
The interior layout of the pump, when the transmission fluid temperature is higher than the spontaneous combustion of liquid or for liquid hydrocarbon transport, and other external gear pump are respectively arranged in each room, and separated by a firewall. For open or semi open layout of the pump, general pump and prime mover so that the axis and the vertical axis of pipe gallery. Pump arranged in the interior, is generally not considered motor vehicles require maintenance. Between the end of the electric petrol pump or pump side and the wall spacing should not be less than 1.2~1.5m, between the two rows of pump spacing of not less than 2m; reciprocating pump power of steam side and side parts for pumps should be left out of the location of the piston and rod; vertical pump arranged in the pipe below the gallery below or above the frame, pump body should be set aside. Installation and maintenance required space; piping layout, the pump on both sides to do at least one side for repair.
Internal gear pump working principle, is the technology provides, internal and external gear pitch circle on one side, the other side is "crescent plate 'two separated, gear to rotate in the same direction, no trapped fluid phenomenon, gas station pump advanced structure, small size, large flow, low noise, long life. Structure characteristics gas transfer pump of internal gear pump for conveying a variety of light, hydraulic piston pump volatile liquid, or heavy, viscous liquid, semi-solid or liquid. Widely used in petroleum, chemical, oil, paint and other industries. Internal gear pump for conveying saponin, silicone oil, rosin, medium high viscosity coating and so on, a wide range of applications. Gear internal gear pump structure.
Marine fuel dispensers in combustion engines is the role of the same amount of fuel in the fuel from the mains to nozzle, therefore, marine fuel dispensing machine state directly on the distribution of temperature field in combustion and had an impact, especially for heavy oil firing unit, oil temperature and oil on the marine influence of fuel dispenser life is great, how to maintain the long-term stable operation of the fuel distributor, is a topic of the power plant are more concerned about the. Machine for the combustion engine, the fuel distributor for use, the use of 10 years especially burning heavy oil, continuous exploration, has accumulated some experience. Company's marine fuel dispensing meters is composed of 10 positive gear pump gear pump units, each including the same size of two gear, the short axis of each unit are connected in series into a whole, the same speed, still can equal allocation of fuel to ensure export each unit in the back pressure under different circumstances, with a starting motor, in starting motor drive by 5 seconds, followed by motor power loss, power distributor work by the pressure difference between import and export of offer, an overrunning clutch between the motor and the distributor, when the motor stops working, the distributor speed exceeds the speed of motor, motor and marine fuel dispensers, the distributor can free running, do not form in the motor load distributor operation.
mechanical pump from the motor and pump two parts. Ordinary mechanical pump driven by the motor shaft rotation through a belt; straight mechanical pump is connected directly to the motor shaft, without intermediate transmission links. The principle is the use of a mechanical pump gas expansion, compression, discharge of the gas from the container extracted. Is called a mechanical pump, because it is the use of mechanical methods, cyclically vary the volume of the pump suction chamber, the gas in the vessel continuously expanded by a pump to the inlet of the suction chamber, and It is discharged through the exhaust port by the compression pump. Change the volume of the suction chamber of the pump piston reciprocating manner, stator and rotary vane type, called a reciprocating mechanical pump, mechanical pump stator and rotary vane mechanical fuel dispenser. Due to practical applications, rotary vane mechanical pump to use more, is to rotary vane mechanical pump as an example of their work.
fuel pump dispenser are auto parts industry jargon. It is one of the basic components of EFI vehicle fuel injection system. Role is to suck the fuel from the fuel tank, after the pressure supplied to the supply pipe, the fuel pressure regulator and with the establishment of some fuel pressure. diesel hand pump by the electric motor, pressure limiter, check valve structure, the electric motor fuel pump actually work in the shell, do not worry, because the shell does not have any thing can ignition, fuel can lubricate and cool the motor fuel, the oil port was equipped with check valve, pressure limiter is located in the pump housing on the pressure side, with access to the inlet channel.
fuel transfer hand pump is directly driven by a diesel engine can be started in a relatively short period of time and to achieve the water supply of electromechanical equipment. diesel hand pump is set microelectronic technology, digital technology, computer technology, information processing technology, industrial automation and control technology, communications technology and mechanical technology of high-tech products as one of its features are automatic start, automatic charging, automatic alarm, automatic preheating, Automatic even try, you can also request to set another alarm output, with telemetry, remote, remote control functions. Troubleshooting methods.
