shaft coated with oil, and bandaged. Motor storage environment is 10% ~ 90% RH, -20 ~ 65 ℃ motor transport and storage process to avoid water, moisture and any corrosive gas as possible.

⑤ hydraulic motor maintenance required by professional installation and maintenance. Users generally not to disassemble repair. With the dismantling conditions, you should read the instructions carefully after, but you must note the following.

a. When decomposition, careful not to knock the hair bruised parts, especially to protect the moving surfaces and sealing surfaces good parts. The decomposition of the parts put in a clean container, to avoid collision with each other, prohibit the use of the hammer decomposition and assembly.

b. Remove the parts should be carefully examined for wear parts to repair and do not substantially more for replacement. To replace all the seals principles.

c. All the parts before assembly should be cleaned, blown in, not use cotton, rag wipe parts, assemblies, places and use tools should be cleaned after the rotation of the output shaft assembly should be flexible without catching phenomenon.
Piston pump maintenance: proportional valve which features?
Proportional valve which features? Piston repair factory Xiao Bian noted below electric proportional valve control continuous control, its main feature is the output with the input amount will change with changes, there is a certain proportional relationship between output and input, proportional control with open-loop and closed-loop control difference.

1) Electrical proportional valve and remote control can be achieved.

2) Use the power of small, low noise and less heat.

3) Electrical proportional control valve and intermittent phase comparison, more streamlined system, the element is also greatly reduced.

4) does not appear the fire, it will not pollute the environment, less affected by temperature changes.

5) enables the stepless adjustment of pressure and speed, avoiding normally-on switch type valve commutation occurs when the impact of the phenomenon.

6) and hydraulic proportional valve comparison, the electrical proportional valve smaller, lighter important, and low cost, simple structure, but the disadvantage is slow in response speed than the hydraulic system of the load change is also very sensitive.

The above is the introduction of electrical proportional valve characteristics, hoping to help you understand, if you want to know the contents of the proportional valve repair, you can view the site related articles.
Before using the high-pressure pump dredge pipeline should pay attention to what?
1, between the high-pressure oil pump pipe cleaning, we must first check the nozzle, the nozzle to ensure that it does not appear the phenomenon of clogging.
2, during the cleaning and construction time, we need to pay attention to is the location to place the nozzle. Usually the nozzle should pipe approximately 30 cm into place, and then the pressurization of the nozzle, the nozzle is fed into the pipeline which, in this position the placement and pressing operations are very important.
3, after completion of the cleaning work, we have even pulled out of the nozzle from the pipe, in order to avoid nozzle swinging staff harm, should the pressure of the high pressure pump to zero as soon as possible.
