A pneumatic-hydraulic foot pump with a nominal oil pressure of up to 70 MPa is designed to create pressure in a variety of systems. Such devices have a number of characteristics, which, of course, differ depending on the model, but there are several basic ones.
Instrument Description
Such devices have a number of characteristics that are basic. For example, the volume of a tank of equipment that is measured in liters. It is worth paying attention to such parameters as nominal pressure and pressure in the pneumatic system.
As for the basic elements necessary for the operation of the air-hydraulic pump, it is a breathing valve, a tube for filling the system with oil, a pedal, a lubricator, a screw for pumping air and a plate that is responsible for adjusting the pumping intensity.
Preparation and operation of the device
Before starting operation of the pneumohydraulic pump for the press, it is necessary to inspect it visually. You need to make sure that there are no fluid leaks, any damage of a mechanical nature, and also that there are no damage to any individual parts.
If the device is being commissioned for the first time, it is recommended that you read the instructions for use, which are usually attached. All hydraulic and pneumatic connections must be securely tightened before use can be made. This is necessary so that during operation, individual parts are not disconnected.
In addition, before proceeding to use, it is necessary to drip a few drops of oil for pneumatic tools in the lubricator. After that, it is screwed into the hole connected to the pneumatic line. Then you need to connect the pump and let it run for a few seconds so that it can distribute the lubricant to the equipment. After that, it is already possible to connect the equipment to the air-hydraulic pump, and more precisely, to its pneumo-hydraulic part.
As for use, it is quite simple. The device has a plate with which it sets the pump intensity before work. Then, using the foot pedal, you can start pumping oil. During this stage, you need to ensure that there are no leaks anywhere. After the end of work, the pedal is released and pressed towards the valve through which oil is pumped out of the device.
Storage
It also happens that the air-hydraulic pump is simply stored for a long time. After that, if it is necessary to use it, certain procedures should be carried out.
It is necessary to disconnect the pump from the pneumatic line to relieve pressure. After this, you must also disconnect the hydraulic hose from the device. All parts are thoroughly cleaned. It is necessary to put on a cap that will protect the elements from dust.
As for the storage of the air-hydraulic pump, it should be in a dry and clean place, which will be completely protected from direct sunlight. After this, it will be necessary to carry out certain work on adding or replacing the oil.
