When it is necessary to pump

It is important to remember that the life of any tool and equipment without maintenance is limited, and the hydraulic machines are no exception. On the one hand, these devices refer to the category of maximum reliable and enduring, however, and they require regular care. Most often, users have to face faults that reflect on the pressure inside the cylinders.

As a result of such problems, the height of the rod’s lift is significantly reduced, as well as the ability to hold the cargo. At the same time, the performance indicators may decrease both gradually and sharply. In such situations, one of the effective ways to solve the problem can be pumped by a jack, during which the air will be expelled from the system and replenish the supply of working fluid.

To maximize the operational elimination of any malfunction, you must first decide on its causes. Timely and accurate identification of the vulnerable place of the mechanism will help promptly restore its performance.

It is no secret that it is the oil that performs the functions of the working fluid in any hydraulic device, is responsible for creating pressure necessary for lifting and fixing cargo. Based on this, we can conclude that most problems are related to it. The enforcement of the system leads to the following faults:

  • Reducing the working length of the rod;
  • The appearance of spring depreciation of the stop with minimal loads;
  • substantial slowdown of the lift;
  • Reducing the lifting capacity of the jackrat.

Most often, the source of all the troubles are enforcement of cylinders of a hydraulic jack and the loss of sealing of individual elements of the design of the lifting equipment. However, in practice, it is also faced with the failure of the check valves. Due to the fact that the shut-off ball is knocked down, the spring, the working fluid ceases to be collected in the desired chamber. In such situations, it will have to fully disassemble and replace damaged items before pumping the jack. Execution of such works will be more rational to entrust the experienced specialists of the service center.

Instruction

Initially, it is necessary to determine exactly what is meant by “pumping” in relation to modern lifting mechanisms. We are talking about a complex of actions aimed at extrusion of air from hydraulic cylinders. In this case, the whole process comes down to pumping the working fluid by the pump. This is exactly the determining factor in the appearance of the name of the procedure, which is one of the most important items of maintenance of lifting devices.

At the same time, it is worth noting that it is possible to get rid of the air in the jack system and without using the mentioned pump.

Those whose disposal was the old hydrocommcrate or a relatively new sample of modern lifting equipment with obvious signs of convulsion, it is necessary to know how to quickly cope with such a problem. Now online you can find a large amount of relevant information. First of all, it should be noted that in order to effectively restore the performance of the device, the standard instrumental arsenal will need, as well as about 300 ml of ordinary mineral oil or special fluid for hydraulic systems.

How to pump a hydraulic jack?

For effective pumping of the bottle type hydrodomkrath, you will need to perform the following steps.

  1. First of all, it is necessary to find the bay hole, which is maximally sealed by a rubber plug. In the overwhelming majority of cases, it is located at the top of the device. Taking into account the structural features of different models, the plug is recessed into the case or repelled over it.
  2. Open an oil bay hole, carefully pulling the plug to avoid damage.
  3. In full to merge all the working fluid. It is worth considering that this measure is relevant when it is necessary to serve the old hydraulic acid, which was actively operated for a long time without carrying. To complete the removal of oil residues, you should unscrew the bypass valve and immediately lower the piston.
  4. Rinse cylinders using special fluids, as well as kerosene or oil that will be after. To do this, pour the flushing tool through the previously mentioned hole, pumping the piston to the top point, and then open the valve and lower the rod until it stops. This procedure is required to repeat several times.
  5. Fill the hydraulic cylinder with oil, placing a bottle of hydraulic acid in its working, i.e. vertical position. Experienced users and specialists advise to use syringe.
  6. After the capacity will be filled to the limit level, twist up to the exposure valve stop. At the next stage, the movements up / down movements are raised devices until it stops.
  7. After you need to unscrew the valve a bit and manually omit the piston when the bay hole is open. This sequence of actions is repeated several times.
  8. If the described algorithm has not brought to the desired results, and air remains in the system, then you can turn the shut-off valve to several turns, raise the piston manually and sharply lower it. In this case, the use of the pump is excluded. Such manipulations are repeated several times, and with each approach decreases by 1 cm length on which the rod is put forward. As a rule, similar radical measures allow you to quickly get rid of the air in the hydraulic system.

The hydraulic lifts of the subframe type are characterized primarily by increased lifting capacity. At the same time, the main operational indicator directly depends on the tightness of the system and the pressure generated in the working chambers. To maintain the full performance of rolling models, they are required to periodically pump.

The source of problems with this category of hydrodomkrats may be pollution and air entering. Correct the situation in several ways. The first version of the pumping equipment includes the following steps:

  1. open the filling cork for oil;
  2. unscrew the bandwidth;
  3. rapid movements to pump a working cylinder;
  4. Wrap the valve until you stop and close the bay hole tightly.

Unfortunately, in some situations, the manipulations described above are not able to fully squeeze air from the hydraulic system. At the same time, many are interested in how to reveal his remnants in the cylinders of the jack.

It should be noted that during the operation of the lifting mechanism, the air will definitely manifest itself. About his presence will be evidenced by the poor job of the device or its full failure.

In such cases, it will be necessary to find a locking needle, which is an integral part of the design of any modern subframe hydraulic. It turns into 2-3 turns, after which in manual mode, the piston should be pulled out several times until it stops and return to its original position. As a result of similar manipulations, as in a situation with bottled equipment models, the air will be completely squeezed out of the system.

Recommendations

It is well known that the key to the long and full functioning of any mechanism, regardless of its purpose, is competent operation and timely, high-quality service. That is why motorists are recommended to know how to properly pump automotive hydraulic jack with their own hands. This will maximize the service life of the equipment and ensure the safety of work with its use.

The rules of operation of hydrodomkraths, including security equipment, are developed taking into account the long-term experience of the instrument manufacturers. It is necessary to pay attention to the following important points:

  • Frequent overload and lifting at the limit height entail the inevitable output of the equipment. Stem curvature inevitably lead to air penetration, and pumping in such cases will be useless.
  • The jack itself is required to install on a rigid, as much as possible. Similar requirements are presented to the point of the stop on an elevator car or other cargo.
  • When you descend, it is necessary to smoothly unscrew the bypass valve strictly by one turn, otherwise the working fluid will be moved too quickly between compartments, which will entail the shipping by jerks, and will also increase the risk of convolution.
  • Prevent the occurrence of the need for pumping will help proper transportation of the lift. Bottle and rhombic hydraulic machines should be transported in a vertical position, and with a rigged design – in horizontal.
  • Separate attention deserves care for moving parts of the device. It is primarily understood by the exclusion of risks of corrosion formation on mirror surfaces, which negatively reflects on the operational qualities of equipment.

It is important to remember that pumping hydraulic jacks is including preventive measure. Often it allows you to prevent serious breakdowns, and, therefore, avoid expensive repair or buying a new lift. It is understood that pumping jacks are recommended periodically. In this case, the frequency and number of pumping is determined by the intensity of the use of the jack.

So, a hundred such a procedure is repeated at least than a monthly. With a garage, rare operation, it will be enough to pump it several times in the year. Unchecked maintenance may be required in the following cases:

  • The presence of a large number of extraneous particles in the liquid. Similar impurities are able to significantly reduce the efficiency of jacks.
  • The formation of bubbles indicating a violation of the tightness and enforcement of the hydraulic system.
  • A sharp and significant reduction in working capacity. Once the equipment ceases to raise the loads declared by the manufacturer, the cylinders should be pumped.
