Maintenance operation of excavator hydraulic pump
If the platform cannot rotate in one direction, it is generally caused by the pressure of the secondary relief valve that cannot rotate. At this time, the secondary relief valve that can not be rotated can be adjusted and the cap can be loosened. A pressure gauge can be installed in the rotary oil path to allow the driver to operate the pilot handle that controls the rotation. The maintenance personnel can adjust the secondary relief valve from side to side. Observe whether the displayed value of the pressure gauge changes. If there is a change, adjust the pressure value to the design overflow value; if there is no change, it may be caused by the following reasons:
Do you know the power of diesel generators?
When using a diesel generator set, you must have a certain understanding of its power. The generator supplier will give you a brief introduction to the following types of power:

First, continuous power (COP). Under the agreed operating conditions and in accordance with the manufacturer's regulations for maintenance, the generator will continue to run at a constant load and the maximum power for an unlimited number of operating hours per year.
What type of generator set do you value?
I believe many people know that when choosing a Cummins generator set, the choice of model is very important. And a high-quality Cummins generator set is what we need most. In order to achieve the effective power generated by the generator, different generators and different types of generators should also be used in a suitable environment.
Installation technical points of generator equipment
1. Installation procedure of generators The installation procedures of generator equipment are mainly: stator in place → hydraulic pressure test of stator and rotor → generator through rotor → installation of hydrogen cooler → adjustment and installation of end caps, bearings and sealing pads → installation of exciter → pair of wheels Find the center again and connect → overall airtight test, etc.
Flame preheating start of diesel generator at low temperature
In the diesel generator starting mode, the common main methods are filling cold start fluid, flame preheating start, circulating water heating system and other preheating methods. At low temperatures, the increase in fuel viscosity is not conducive to the atomization and combustion of fuel. Poor lubricating oil fluidity will increase the resistance of various moving parts. In addition, factors such as the decrease in the battery's working ability will easily cause the generator to start difficult , Wear of parts, reduced power, increased fuel consumption and reduced power performance. Here, I will briefly introduce some matters about the flame warm-up start.
Causes and hazards of stepping motor out of step
A comprehensive analysis of the causes of stepping motor out-of-step in the process of economical numerically controlled NC warships, and corresponding solutions are proposed.
The open-loop CNC system composed of stepping motor and drive circuit has been widely used in economical CNC machine tools due to its simple structure, low price and reliable performance, and plays an important role in the numerical control process of China's machine tool industry. status. Stepper motors are often used for precise positioning, so it is important to ensure that the motor does not lose steps.
