discoloration, it must be replaced.

????When replacing bearings, bearing should pay attention to the original letters and models were powered by piston bearing large load bearing capacity, it is best to buy the original manufacturer, the original specifications of the product, if the replacement of another brand, you should consult an experienced bearing The staff look-up table on the exchange, the purpose is to keep the level of accuracy and load bearing capacity.

????High pressure fuel pump drive can also be used to save energy, high-pressure pumps in the actual production process, the case usually are running in pressure or flow to regulate working conditions. When the actual pressure is greater than the need for pressure, through the relief valve to adjust to the working pressure is stable so that the relief valve discharge excess. The motor has been running at full speed again in action, power unchanged.

????Valve plate has a plane equipped with stream flow and spherical forms. Deputy spherical friction with stream flow in the cylinder with relatively shallow surface scratches, repair by grinding means; cylinder with flow surface grooves deeper, it should first use "after surface engineering technology" means filled trench, then grinding not blindly grinding ,, to prevent copper layer thinning or spill out of the steel substrate.

???When the overflow to regulate the pressure and flow, there is an overflow back to the original balance of the system, resulting in the presence of unwanted power piston, low efficiency, if used after Year-saving drive, the relief valve can set it closed through energy converter itself automatically adjust the working pressure, working pressure is stable, automatic tracking pressure equipment. Automated control, thus saving energy. The biggest advantage of this adjustment method is the ability to reduce the energy consumption of high-pressure pumps, energy-saving effect of up to 30%.

The specific role of the high-pressure pump

Increase the fuel pressure, high-pressure injection, to achieve the best atomization, high-pressure pump is the power source for critical uses as jacks, upsetting head, a Zhahua, extruders and other hydraulic devices.

High-pressure pump installation sequence is as follows: During the installation of the high-pressure pump being, in order to avoid debris to fall into the machine, all units should cover the perforations. The unit on the basis of anchor bolts buried in between the base and the base, using a pair of wedge pad for correction. Correction shaft and motor shaft concentricity, on the road linking the outer shaft, the allowable deviation 0.1 mm; two coupling plane gap should ensure that 2 to 4 mm, (a small pump to take a small value) gap should be uniform, allowing difference 0.3 mm. After the connected piping and determine the motor direction of rotation, connect the coupling, and then check it again concentric aromatic shaft. After the actual test run the unit 2 to 3 hours, for a final check, if no adverse phenomenon, is considered qualified to install. In the commissioning process, check the bearing temperature and vibration are as follows: Loosen the coupling large, with a horizontal instrument were placed on the electric oil pump shaft and the base, by adjusting the wedge pad, correction unit level, tighten the bolt appropriate to Anti-around. In order to prevent pipeline debris into the pump, to the newly installed pipeline should be installed in the pump glue filter, the effective cross-section should be greater than 2 to 3 times the suction pipe section.

Piston overhaul

(1) Check the plunger there is no scar and corrosion phenomenon, when necessary, should be replaced new.

(2) Check the plunger deputy with the situation. The plunger tip is inserted into the plunger comprising a tilt of about 60 °, if the plunger can slow the decline in its role as a good fit.

(3) Check the plunger seal deputy. Hold the plunger sleeve, two fingers to block the plunger tip and the side of the inlet. Pull the plunger with the other hand, feel a greater attraction, relax plunger is retracted immediately situ, indicating piston secondary seal is good, or to replace the piston pair.

(4) Check the oil pressure valve annulus vice is not worn or injuries have stepped phenomenon, when necessary, should be replaced.
