Causes and solutions for high voltage on generator stator temperature wiring:
1) Damage to the stator coil temperature measuring point causes false alarms if the temperature at a certain point measuring temperature is too high; high, find the relevant temperature measuring points according to the stator coil temperature measuring point distribution map, analyze and determine, and then contact for maintenance
2) The temperature of internal cooling water is high, it is; It is recommended to open the cooling water valve of the internal cooling water cooler or bypass the manual door. If this has no effect, you can check the operational status of the open water filter and the seawater booster pump. Refer to the operation of the water circulation system. To rinse the filter, start the pumpseawater boost and activate the open water filter;
3) If the opening of the circulation door of the internal cooling water pump outlet is too large, resulting in a low amount of internal cooling water. pressure, the opening can be adjusted to make the internal cooling pipe water pressure normal (generally around 0.24); the flow rate of the internal cooling water pump is insufficient or the internal cooling water pump trips. At this time, the pump should be connected in time;
5) If the internal cooling water filter is dirty, it can be switched and cleaned. Therefore, it is recommended not to operate with dual filters under normal circumstances; operation.
6) If the internal cooling water cooler is dirty, you can install a movable cooling water outlet door or change the cooler
7) The internal cooling water coolerThe internal cooling water is leaking and the Internal cooling water is flowing down the coast. If the return water pipe leaks, the flow rate of the internal cooling water decreases and the return cooling water temperature of the internal cooling water increases abnormally, which can be solved by switching the cooler;
8) Installation of the ion exchanger for internal cooling water When transporting, please note that the ion exchanger can only be placed in the ion exchanger after the water is filled and the air is completely exhausted;
9) The continuous exhaust air door from the internal cooling water chiller, ion exchanger, internal cooling water filter to the water tank internal cooling water is not opened, resulting in an increase in local water resistance in these containers; it is recommended to check this item during operation. Generally, if the exhaust air door is opened, the temperature of its pipe and the internal cooling water will be the same;
10) Internal cooling siphon return door. generator water It is not turned on. You should pay attention to this problem when starting the machine;
11) The water level in the internal cooling water tank is low. During operation, you must ensure that. water replenishment is automatic and easy to operate, and strengthens monitoring of water level changes of internal cooling water;
12) System pipes or valves are leaking, reinforce the inspections;
Does the height acting hydraulically refer to the total height? I didn't find such a statement in the manual...
There are two types of motorcycle engine stalling: sudden stalling and gradual stalling. The causes of the failure are therefore relatively complex, when checking the timing. failure, you should rely on the operating conditions of the engine before stalling to thoroughly analyze whether the engine stalls, such as turning off the ignition switch. This is usually due to a fault in the ignition circuit. In addition, the main switch or cable connector falls off, which can also cause sudden motor stalling if the motor stalls before being accompanied by a short circuit. Lean process, it gradually stops. Is this due to a failure in the oil circuit? It is easy to stall while idling at high speeds, prinmainly due to incorrect adjustment of the carburetor idle speed. If accelerated to high speed, it is easy to stall. This is usually due to poor carburetion acceleration performance. Therefore, targeted inspections should be carried out after parking to eliminate the defect as quickly as possible. When the motorcycle suddenly stalls while riding and cannot continue to start, you should do the following: 1. Check whether the fuel is exhausted. Judge whether the engine speed increases suddenly and automatically before stopping. If so, it's the fuel. If there are no more, you must ask passing vehicles for help. When refueling, you can use a plastic hose or tube to refuel using the siphon principle. However, at that time, the motorcycle lacking oil must be lower than. the fuel tank that supplies the vehicleicle. You can also use the oil tank guard on the motorcycle. The magneto guard, plastic bag, etc. are used as containers for refueling, but when refueling the fuel switch must be placed "off". " position to prevent gasoline from flowing into the cylinder from the carburetor. 2. Check the battery wiring and the various low voltage wire joints. If there are high voltage wire harnesses and terminals ignition coil, repair them in time 3. If the above situation is normal, but before stopping, the engine speed becomes unstable, the motorcycle wobbles while riding, the speed becomes low when throttle. is lowered and the engine stalls, it must be considered that the battery power is insufficient, because when the engine speed is high, due to When the engine provides energy for ignition, the engine can maintain its operation when the speed ofdriving changes, the generator output current also changes accordingly; The ignition is interrupted and the motorcycle sets off. When the accelerator is lowered, the speed decreases, the generator does not produce electricity or the current is very low and the spark plug does not light and stalls. 4. Check the spark plug for failure or carbon deposits and perform a flashover test on the spark plug. If there is no spark between the spark plug electrodes or the spark is red and short, it means that the spark plug is not working well. You need to check whether it has carbon deposits, whether the insulation performance of the spark plug meets the requirements. whether the spark plug is wet, etc., and clean it according to the specific situation. 5. Check whether the ignition coil is short-circuited. If so, it will need to be replaced in time. 6. If the power gradually decreasesing while driving and sometimes you hear a metallic friction noise in the engine and then suddenly stalls, the engine may have a sticking cylinder. 7. If the engine suddenly emits an abnormal and disordered noise. or knocking noise while driving then parking may be caused by the screws on the clutch backing disc being not tightened and the safety punch point not being riveted, or the The transformer speed gear is broken, the forks break or the transmission chain breaks and falls and gets stuck on the main shaft sprocket. The engine stalls and stalls at this time, it should be eliminated according to the specific situation.
Does the hydraulically acting height refer to the total height? I didn't find such a statement in the manual...
Does the acting head mentioned in hydraulics refer to the total head? I do not havenot found such a statement in the textbook... In fluid mechanics, total height includes position height and pressure height. The action height is the sum of the exit velocity height and the pipeline loss height.
Is the maximum height of the generator equal to the total height? What is the concept of total water height? Maximum height generally refers to the maximum gross height.
In fluid mechanics, how does the term total acting height explain position height + pressure height + velocity height
Why does the pipeline does it suddenly expand and the total load line first decreases sharply and then slowly?The hydraulic knowledge of the side pressure line head pipe suddenly explains that the pressure line head pipe is a pipe connecting the liquid levels of the pressure lines at different poMeasuring ints along the water flow direction. It reflects the potential energy of the fluid. The head pipe line may decrease along the line. It can also increase (as the pipe diameter increases in the direction of flow). \r\nThe total head line is the base line of the pressure pipe head line plus the flow head. It reflects the total energy of the fluid. Since there is always a pressure loss in the direction of flow, the total head line can only go down. , can't get up. \r\nThere are many flow rates with regional pressure drop, such as: \r\n1. Flow through elbows\r\n3. Flow through tees\r\n4. between large and small pipes\r\n5. The flow rate in the water inlet pipe of the water tank
Water head is actually a popular term for groundwater pressure. For example, if the water table level is -2.0 m,then for a place with an altitude of -3.0 m, the height of water fall is 1.0 m. The water table pressure here is then 10*1=10KPa. If the height of water fall is 10 m, then the water table pressure is 100 KPa.
In fluid mechanics, how to determine the starting position of the total head line?
The starting position of the total head line is determined relative to the baseline.
The baseline, the 0-0 line, can be selected arbitrarily.
When the 0-0 baseline is selected, the following three items can be determined
Head position: Z (unit: m)
Pressure head: p /(ρg); unit: m
Velocity head: v^2/(2g); unit: m
Then the starting position of the total head line is: Z+ The height position determined by p/(ρg)+v^2/(2g).
What is headline and hydraulic gradient? What is the relationship between thetotal head line, pressure driving head line, and position head line? 1. Head line: the curve connecting the water head to ? the ground fault section is the water height line, where the water height represents the potential energy of the water (fluid), and the dimension of the water height is the length.
For example: the height of water (liquid) at a place is Z, which means the potential energy of water (fluid) of height Z.
2. hydraulic gradient: solid materials in two-phase flow are generally transported in turbulent flow, and their degree of suspension depends mainly on the mud flow rate related to turbulent diffusion. certain pressure, the slurry flows into the pipeline. Friction with the pipe wall and resistance between layers during turbulent flow must be overcome, collectively called frictional resistance loss, i.e. hydraulic slope.
Hydraulic Slope, also known as WATERSURFACESLOPEORGRADIENT: The fall per unit distance from the river surface, commonly expressed as percent, thousandths and ten thousandths. For example, if the distance between points A and B on a river is 100 kilometers and the water level at point B is 20 meters higher than that at point A, the hydraulic gradient is 2/10,000 (20 meters divided by 100 kilometers, that is, 20 divided by 100,000
3. Relationship: the total head line of the reducing pipe and the pressure measurement.The head line of pipe is not parallel and the position of the siphon pipe head line may be higher than the total head line and the pressure pipe head line
The head line. of the pressure tube is the line connecting the liquid levels of the pressure tube at different measuring points along the direction of water flow. It reflects the energy.potential energy of the fluid. The head line of the pressure tube can go down or up. the driving. (When the pipe diameter increases in the direction of flow).
The total head line is the base line of the pressure pipe head line plus the flow head. It reflects the total energy of the fluid. Since there is always a pressure loss in the direction of flow, the total head. The line is along the road. It can only go down, not up.
There are many flow rates with regional pressure drop, such as:
1. Flow through valves
2. Flow through elbows
. 3. The flow through the tee
4. The flow through the connection between the large and small pipes
5. The flow rate in the inlet pipe of the water tank
In fluid mechanics What is the authoritative explanation of the term total action head? The head position + pressure head + speed heade is interpreted by the authority of the parents as the same as that of the father and the mother!
Hydraulics The theoretical value of the regional pressure loss coefficient at the inlet of a sharp-edged pipe is calculated according to the material and process using formulas, and the actual value is measured in the actual process.
There are certainly differences. The main reason is: there must be a gap between the produced things and the theory, and the shape of water flow cannot be the theoretical shape.
The pressure loss caused by the rapid change of regional boundary leading to change in flow structure, change in flow velocity distribution and generation of vortex zone is called regional pressure loss, represented by hj.
Causes of regional pressure loss:
The main reason is that when the fluid passes through a regional obstruction, due toof inertia, the main flow separates from the wall, forming a vortex zone. , and the fluid particles in the vortex area Strong turbulence consumes a lot of energy; at this time, the particles in the vortex area are continuously transported downstream by the mainstream, which intensifies the turbulence of the mainstream in a certain downstream range, thereby increasing energy loss; Near the regional obstruction, the flow velocity distribution is constantly adjusted, which will also cause energy loss.
Excuse me, what is the relationship between head loss and head free? It depends on how you calculate. In wastewater treatment, this is usually a value and not a calculation. Head of water reserved. Based on 0.5-1.0 m. Taking too much of a free head is a waste of energy. The head selected by the water pump includes the suction pressure loss et of water outlet, the difference in lifting water level and the headroom.
