If you want a budget-friendly generator, why not try Chinese local brands like Weichai, SDEC...

Check the fuel level: Make sure that the generator has enough fuel to operate. If the fuel level is low, add more fuel and try starting the generator again.   Check the fuel lines: Inspect the fuel lines for any signs of damage, cracks or leaks. If the fuel lines are clogged or damaged, they will need to be repaired or replaced.   Check the fuel filter: A dirty or clogged fuel filter can prevent fuel from flowing to the engine, causing the generator to not start. Remove the fuel filter and inspect it for any signs of dirt, debris, or blockage. If the fuel filter is dirty, it will need to be cleaned or replaced.   Drain the old fuel: If the fuel in the generator is old or has been sitting for a long time, it can cause the generator to not start. Drain the old fuel from the tank and replace it with fresh fuel.   Check the carburetor: The carburetor is responsible for mixing fuel and air to provide the engine with the proper fuel-to-air ratio. If the carburetor is clog...

  1. Inspect the connections: Check all the electrical connections to and from the generator for signs of looseness or corrosion. Tighten any loose connections and clean any corrosion using a wire brush and a solution of baking soda and water.   2. Check the starter: Check the starter solenoid and the starter motor for any signs of damage or wear. Test the starter by using a multimeter to check for continuity and proper resistance. Replace the starter if it is faulty.   3. Check the generator control panel: Check the generator control panel for any warning lights or error codes. These can provide clues as to what is causing the electrical problem.   4. Check the fuses and circuit breakers: Check the fuses and circuit breakers for any signs of damage or wear. Replace any faulty fuses or reset any tripped circuit breakers.

  Generator containers, also known as generator enclosures or generator housing, are specialized structures designed to house and protect generators from outdoor elements. These containers are typically made of steel, aluminum, or other durable materials and come in various sizes and shapes to fit the generator's size and application.   Generator containers are popular in remote areas, construction sites, and outdoor events where power supply is not readily available. The containers are customized to accommodate the generator and other auxiliary equipment such as fuel tanks, exhaust systems, and cooling systems.   The benefits of using generator containers include:   Protection from the elements: The container offers protection against harsh weather conditions such as rain, snow, wind, and extreme temperatures. It ensures that the generator runs smoothly without being affected by these weather conditions.   Sound reduction: The generator container also serves a...

Due to structural constraints, diesel generator sets cannot be completely waterproof. When the rainy season/typhoon season comes, diesel generator sets may be affected by natural disasters such as floods and rainstorms. When water enters the diesel generator set, the user must take necessary measures in time, disconnect the external power supply and battery connection line, do not run the engine, do not try to rotate the crankshaft, and prohibit running the engine. At the same time, check the water inflow in various parts. Common problems with water inflow Check whether the drainage components of the exhaust pipe (the lowest point of the exhaust pipe or the muffler) have water discharged. Check whether there is water accumulation in the air filter housing and whether the filter element is soaked in water. Check whether the rotating parts such as the radiator, fan, coupling, etc. are blocked. Whether there is oil, fuel or water leakage outside. Remove the rocker cover and observe whethe...

Hosem generator sets are primarily used in critical environments to quickly restore power and extend supply time during a power outage or emergency. Such power loads are referred to as primary loads. For systems like communication equipment, instruments, and computer systems that have strict requirements for uninterrupted power, in addition to a generator set, a backup battery or UPS should also be installed.   The operation of a Hosem generator set has two key characteristics:    1. Emergency Use: The continuous operation time is usually short, generally needing to run for only a few hours (≤12h). Emergency Generator For Commercial Building Standby Power Generation 2. Standby Use: The emergency generator set remains in a standby mode most of the time, only starting up when the main power source fails. Once the main power source is restored, the generator set will automatically switch off. Standby Power Generators | Cummins Powered   Determining the Capacity of D...

Section 1: Common Causes of Abnormal Frequency in Generator Sets   1. Engine Speed Issues   Explanation: Generator frequency is directly related to the engine’s speed (RPM). If the engine speed fluctuates, it will cause frequency variations. Solution: Check the engine’s governor and fuel system to ensure the engine maintains a stable speed. Adjust or repair the governor if necessary.   2. Faulty or Malfunctioning Governor   Explanation: The governor controls the engine speed to maintain a steady frequency. A malfunctioning governor can cause the generator to run at incorrect speeds, leading to abnormal frequency. Solution: Inspect the governor system for wear or damage. Calibrate, repair, or replace the governor as required.   3. Load Imbalance   Explanation: An imbalance in the load distribution across the generator’s phases can cause fluctuations in frequency. Solution: Ensure the load is evenly distributed across all phases. Use a load...
