What should I pay attention to when purchasing piston pump? ZF hydraulic remind you:
1. If it is bulk purchase plunger pump, must choose the regular piston pump manufacturers! (for example: ZF hydraulic)
2 buy plunger pump must sign a formal contract with the manufacturer!
3. Before purchasing plunger pumps in large quantities, be sure to let the manufacturer make pre-production samples for confirmation!
ZF hydraulic branch specializing in providing plunger pump bulk purchase, looking forward to working with you!

Can a plunger pump be pressurized with a booster pump
Plunger pump is a positive displacement pump, theoretically, the head is unlimited, only depending on the mechanical strength of the pump body. But the plunger pump outlet pressure is limited, the control outlet pressure is through the outlet valve to control, and the pump suction pressure has nothing to do.
If the plunger pump outlet pressure is low, and considering in the pump inlet plus booster pump, is not to achieve the purpose.
Add booster pump in the plunger pump outlet, there is a problem of safety, if the plunger pump low flow or damage, easy to cause pump pumping out.
Therefore, it is not recommended to use booster pump.
The best way is to consult the plunger pump manufacturers to see if it is possible to replace the outlet valve in the current working condition, if not, then consider directly changing the whole pump.

The structure of the piston pump is divided into axial and radial piston pump two representative structure; As the radial plunger pump is a new type of high efficiency pump with high technical content, with the continuous acceleration of localization, the radial plunger pump will inevitably become an important part of the application field of the piston pump; See radial piston pump encyclopedia for details; The following is an example of an axial piston pump. Axial piston pump is the use of parallel with the drive shaft plunger reciprocating movement in the plunger hole produced by the volume change to work. As the plunger and plunger hole are round parts, the machining can achieve a high precision with the advantages of high volume efficiency, smooth operation, good flow uniformity, low noise, high working pressure, but more sensitive to the pollution of hydraulic oil, more complex structure, higher cost. The software function displays the current pressure, setting pressure and setting flow in real time. Real-time curve display pump working pressure can be set in two ways flow and pressure, fast and practical; With timing function, it is convenient to set the working time of the pump; Can save the current working pressure, easy to view; Can print current pressure and other important parameters. Advection pump (plunger pump) products are widely used in petroleum exploration and development evaluation experiment, catalytic reaction of petrochemical industry, polymerization reaction, food, pharmaceutical, liquid chromatography analysis, supercritical extraction, separation, atomic energy science, environmental science, process equipment, experimental equipment and micro liquid delivery of various liquids. The performance indexes of TBP series advection pump (plunger pump) can meet the requirements of fluid flow rheological characteristics research in oil field, fill the gap of equipment manufacturing in related experimental technology field in China, and reach the international advanced level of similar instruments. Main features and functions 1. 2, motor soft start, reduce the impact on machinery. 3. No high pressure throttling energy loss. 4, with under voltage, over voltage, overload, short circuit, lack of equal automatic protection. 5. Replace the original system. Reduce purchasing cost (new equipment purchase). 6. Reduce the maintenance cost of machinery. 7. Easy operation and remote control. Plunger pump is an important device of hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder block, so that the volume of the sealed working chamber changes to achieve oil absorption and oil pressure. Plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow regulation. It is widely used in high pressure, large flow and flow needs to be adjusted occasions, such as hydraulic press, construction machinery and ships. Mechanical maintenance adopts plunger pump supplied by supplementary oil pump. After 3000h, the operator shall check the plunger pump 1-2 times a day to check whether the sound of hydraulic pump is normal. If it is found that the speed of the hydraulic cylinder decreases or the engine is not running, it is necessary to disassemble the filling pump and check whether there are scratches on the edge of the impeller and whether the clearance of the inner gear pump is too large. For self-priming plunger pumps, the oil in the hydraulic tank shall not be lower than the lower limit of the oil mark, to maintain a sufficient amount of hydraulic oil. The cleaner the hydraulic oil, the longer the service life of the hydraulic pump.
