    There are generally several situations when the hydraulic cylinder of the dump truck falls back: 1There is a problem with the hydraulic cylinder; 2.There is a problem with the oil check valve in the gear pump, which was originally one-way, but the oil is indeed returned; 3.There is a problem with the check valve in the limit valve, and the oil is returned;

    If it is caused by the problem of the hydraulic cylinder, it is generally not slow and uniform, but a rapid fall to stop; If it is a slow decline after jacking, can not be fixed, I think it is the problem of the check valve (either the gear pump check valve is broken, or the check valve in the limit valve is broken), this situation can only be replaced, you quickly contact the container manufacturer, there are half a year after-sales, even if they are over-warranted, they will generally assist you to find out the problem. Hope it helps.

    If the hydraulic pump of the dump truck cannot be lifted, the solenoid valve will not be energized. The hydraulic pump is broken, the distribution valve is broken. Use the plum wrench afterburner rod to loosen the small pump in the counterclockwise direction, use needle-nose pliers to pry out the gasket, take out the steel ball, clean the recess, put in the spacer, observe whether the steel ball has room to move, and replace the small pump after confirmation, and tighten it.

    The focus of the operation:

    1. When the hydraulic jack is used, the bottom should be smooth and tough. Oil-free planks to enlarge the bearing surface and ensure safety. Iron plates should not be used instead of wooden boards to prevent sliding.

    2. When lifting, it is required to be stable, and after the heavy object is lifted slightly, it is necessary to check whether there is any abnormal situation, and if there is no abnormal situation, it can continue to rise. Do not arbitrarily lengthen the handle or operate it too violently.

    There are generally several situations when the hydraulic cylinder of the dump truck falls back:

    There is a problem with the hydraulic cylinder;

    There is a problem with the oil check valve in the gear pump, which was originally one-way, but the oil is indeed returned;

    There is a problem with the check valve in the limit valve, and the oil is returned; The fallback caused by the problem of the hydraulic cylinder is not slow and uniform, but a rapid drop to stop;

    Like this case, it slowly declines after being topped, and the situation that cannot be fixed is the problem of the check valve (either the check valve of the gear pump is broken, or the check valve in the limit valve is broken), this situation can only be replaced, and the container manufacturer can be contacted quickly, there are half a year of after-sales, even if they are over-insured, they will generally help to find out the problem.

    Hello dear, the hydraulic cylinder of the dump truck sinks, that is because the piston oil seal in the hydraulic cylinder is not strict or the inner wall of the cylinder barrel is strained and the oil unloading sinks, to solve the chaotic nuclear maintenance method, dismantle the cylinder if the cylinder strain needs to be repaired or replaced, if the cylinder is not strained, you can directly replace the fluid to sell the regret pressure cylinder oil seal, the premise is that you need to measure the diameter of the cylinder wall and the diameter of the piston of the hydraulic cylinder to see that the oil seal and the cylinder wall are combined to the limit, if you reach the limit, the oil seal can not be changed in time, The hydraulic cylinder assembly needs to be replaced. I hope my help to Zhongzheng you, thank you, and I wish you a happy life!

    Hello, I'm glad to answer your questions, Dump truck hydraulic roof dropped suddenly when the top of the box fell a section of the roof pump, which may be caused by the following reasons: 1The pressure in the hydraulic system is insufficient.

    Insufficient pressure in the hydraulic system will cause the top pump to not provide sufficient hydraulic pressure to support the weight of the falling compartment, resulting in the falling compartment falling. 2.The internal parts of the top pump are worn or malfunctioning.

    Wear or failure of the internal components of the top pump can cause the hydraulic system to be under insufficient pressure to support the weight of the falling compartment, resulting in the falling compartment falling. 3.Oil leakage from the hydraulic cylinder at the bottom of the falling compartment.

    If the hydraulic cylinder at the bottom of the falling compartment leaks, the hydraulic system cannot provide sufficient hydraulic pressure, causing the falling compartment to fall. 4.Improper operation.

    Improper operation, such as sudden release of the hydraulic lever or forced stopping during operation, can also cause the car to fall. If the chain Qiaoguo suddenly falls a section of the top pump when the hydraulic roof of the dump truck falls into the box, the operation should be stopped immediately, and the hydraulic system and the top pump should be checked to see if they are normal. If you can't inspect it yourself, you can seek a professional to have it repaired and inspected.

    When noisy, it is recommended that you operate in strict accordance with the operating procedures in daily use to avoid similar accidents.

    Hello, with the pie, I am happy to answer for you. There may be the following reasons for the sudden drop of a top pump when the hydraulic top of the dump truck falls into the box:1

    Oil leakage in the hydraulic oil circuit: The connection or seal in the hydraulic oil circuit leaks, resulting in the loss of pressure in the hydraulic system, resulting in the failure of the Peihe top pump to support the drop box. 2.

    Internal damage of the top pump: Some internal parts of the top pump are worn out, falling off and other faults, resulting in the decline of the top pump's efficiency. 3.

    Gas mixing in the hydraulic system: During the operation of the hydraulic system, if there is air mixture, it will cause the pressure loss of the hydraulic system and affect the normal operation of the top pump. 4.

    Design issues with top pumps: If the top pump is not properly designed or installed properly, it can also lead to its failure. It is recommended that you contact a professional maintenance personnel for inspection and repair of the dump truck.

    Before use, please ensure that the equipment of the vehicle is functioning normally to ensure driving safety.

    Summary. The top pump of the hydraulic top drop compartment of the dump truck is used to control the lifting of the carriage, when the carriage is raised, the hydraulic oil will flow into the top pump, thereby driving the piston movement on the top pump to make the carriage rise; When the carriage is lowered, the hydraulic oil flows back to the tank, which causes the piston on the top pump to move downward, causing the carriage to descend. If the top pump suddenly falls down a section when the hydraulic top of the dump truck falls off the box, it may be caused by the following reasons:

    1.Hydraulic system failure: If the hydraulic system fails, such as pipeline breakage, pump body damage, etc., it will cause the hydraulic oil pressure to drop suddenly, causing the top pump to fall one section.

    2.Piston jamming: If the piston on the top pump is stuck, it may cause it to suddenly drop a section.

    3.Insufficient hydraulic oil: If the hydraulic oil is insufficient, it will cause insufficient pressure in the hydraulic system, which will cause the top pump to drop one section.

    4.Problems with the structure of the top pump: If there is a problem with the structure of the top pump, such as aging seals, faulty valve cores, etc., it may also cause it to fall suddenly.

    When this happens, the operation of the hydraulic jacking and falling chamber should be stopped immediately, and the status of the hydraulic system and the top pump should be checked, and the operation should be carried out after troubleshooting. At the same time, it is necessary to pay attention to the maintenance of the hydraulic system, and replace the hydraulic oil and seals in time to avoid similar failures.

    Summary. The oil seal leakage will cause the oil pressure provided by the oil pump to the flip cylinder to be insufficient, and in serious cases, it may affect the work of the flip cylinder: the lifting force of the flip cylinder is insufficient and cannot be lifted normally, or the cargo box falls back during the lifting process.

    The above consequences are with unsafe factors, it is recommended to replace the oil seal in time, the oil seal is normally distributed by the manufacturer as a wearing part, even if it is used up, it is also convenient to procure, it is a standard part, and there are many ways to achieve convenient procurement.
