(B) adopt a Loctite adhesive with the equipment, which we approach begged copper coat the outer diameter of the outer grooves;

(C) bore tapping, threading copper sleeve outer diameter after coating Loctite glue, screw device.

Piston is a major equipment hydraulic system. It relies on the plunger reciprocates in the cylinder, so that the volume of the cavity sealing operation is changed to the end of the suction pressure oil. Piston pumps with a rated pressure, compact structure, high efficiency and flow conditioning facilitation benefits, it is widely used in high pressure, high flow and traffic demand conditioning occasions, such as hydraulic machines, construction machinery and ships in.

Axial piston pump is to use the drive shaft parallel to the plunger in the plunger bore volume change occurred in reciprocation for the job. Since the plunger and the plunger hole are circular parts, can reach very high precision machining and cooperation, thus high volumetric efficiency, smooth operation, flow uniformity, low noise, operating pressure senior interests, but for the hydraulic oil pollution the more active, the structure is more messy, higher cost.

Melting contact information and copper cylinder sleeve, the device measures as follows:

(A) selection of ground rods, craft mechanical way grinding or amend the bore;

(B) the choice of coordinate boring, boring scratch the cylinder bore;

(C) Selection Reamer correction cylinder bore.

(3) selection of "look engineering technology" approach as follows:

(A) plating techniques: the plunger outer layer of hard chrome plating;

(B) electrical brush technique: Brush the plunger outer wear-resistant materials;

(C) thermal spraying or electric arc spraying or spray: Spray carbon martensite wear-resistant materials;

(D) Laser cladding: the plunger outer cladding alloy powder by high hardness.

(4) no copper sleeve cylinder bore of the cylinder material are mostly ductile iron, prepared amorphous thin film or coating on the cylinder wall. Since the cylinder bore wall with this exceptionally substance, so it tune constituting the hard - hard matching friction deputy

When replacing the bearing, should pay attention to the type of original letters and bearing, mostly piston bearing use large load bearing capacity, the best acquisition of the former factory, the original specification of goods, assuming replacement of another brand, you should seek advice on the bearings resume The staff look-up table on the exchange, the intent is to uphold the level of accuracy and load bearing capacity.

Selection charge pump supply piston pump, the use of 3000h, the operator need 1-2 times a day on the piston view, dynamic view of the hydraulic pump is not a normal job. Found cylinder speed drops or stuffy car, you should pump up the collapse of view, is not a view of the impeller edge scratching appearance, internal gear pump room is not too large. For self-suction-type piston pump, the hydraulic oil tank must not fall below the lower limit of the oil standard, should adhere to meet the amount of hydraulic oil. The higher the cleanliness of hydraulic oil, the use of the longer life expectancy of the hydraulic pump.

Piston length of life using the number, and the usual protection protection, quality and quantity of hydraulic oil, oil cleanliness and so on. Avoid the oil parti
