Advantages and Characteristics of Diesel Generator Set PT Fuel Pump

Apr. 13, 2022

Since diesel generator sets are gradually recognized by users as emergency power generation equipment, the sales of diesel generator sets have also gradually increased, but we are still not familiar enough with diesel generator sets. In order to let the majority of users have a better understanding of the unit, Starlight Power Equipment will introduce to you what the PT fuel pump of diesel generator set is. Literally, P means pressure and T means time. The PT fuel pump can scientifically control the fuel supply of the diesel generator set.

The basic functions and principles of the PT fuel pump for diesel generator sets are: delivering fuel from the fuel tank to the engine; providing fuel with a specified flow and pressure to the PT injector; controlling and adjusting the engine speed, load and working conditions.

The characteristics of diesel generator set PT fuel pump are as follows:

1. The PT pump works under lower pressure, and its outlet pressure is about 0.8-1.2MPa, and the high-pressure oil pipe is cancelled, so there are no various faults caused by the pressure fluctuation of the high-pressure system of the plunger oil pump. In this way, the PT fuel system can achieve very high injection pressures, resulting in improved spray quality and high-speed performance. In addition, it is good to avoid the disadvantages of high pressure oil leakage

2. In the PT fuel supply system, the diesel injected from the PT injector only accounts for about 20% of the fuel supply of the PT pump, and most (about 80%) of the diesel is returned through the PT injector. Cool and lubricate the PT injector, and remove any air bubbles that may exist in the oil circuit. The returned fuel can also directly bring the fuel in the injector back to the float tank, which can play the role of heating the fuel in the fuel tank when the temperature is relatively low.

3. Since the governor and oil supply of the PT pump are evenly regulated by oil pressure, the oil leakage can be automatically compensated by reducing the amount of bypass oil to a certain extent, so that the oil supply of the PT pump can be adjusted to a certain extent. It will not drop, thereby reducing the number of maintenance.

4. In the PT fuel system, the fuel supply of all PT injectors is completed by a PT pump and the PT injectors can be replaced individually.

The diesel generator set PT fuel system has a compact structure and simple pipeline layout. In the whole system, only the injector has a pair of parts, and the number of even parts is greatly reduced compared with the plunger pump fuel system. This advantage is in the diesel generator set with a large number of cylinders. more obvious.

Starlight Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
