Repair of a hydraulic distributor Mannesmann Rexroth, Kyiv

Mannesmann Rexroth hydraulic distributor repair, Mannesmann Rexroth hydraulic distributor repair. Repair of imported hydraulic distributors in Ukraine. We carry out both major repairs of hydraulic distributors and "minor" repairs: for example, only replacement of seals or repair of valves, replacement of valves. Checking, adjusting, adjusting the hydraulic distributor on the hydraulic stand.

It is possible to repair only certain spools for certain operations (the spools requiring repair will be marked for you), for example, it does not hold the boom due to large amounts of leakage in the hydraulic distributor.

Overhaul of the hydrodistributor includes several technological processes:

•Preliminary inspection on a hydraulic stand, disassembly and inspection. Assessment of wear and the degree of need for repair of the hydraulic distributor. After carrying out defect detection, our specialists proceed directly to the process of repairing the hydraulic distributor.

• Honing the hole for the spool. This operation is performed by a special honing machine with diamond plates and with a variable diameter of the processed hole. A quality machined hole is one of the factors of small leaks of the hydraulic distributor.

• Measure the diameter of the resulting hole under the spool. Due to the increased diameter of the hole, there is a need to manufacture a new spool. Whenrepairing hydrodistributors we use spools made on CNC lathes.

• TVC surface hardening of the new spool. This is necessary for the wear resistance of the spool. It is surface rather than volume hardening that is preferable for this type of work.

•Grinding of the spool on a circular grinding machine. A well-polished surface allows you to eliminate burrs in the hole. Small values ​​of leaks in the hydraulic distributor are ensured due to the precise adjustment of the size of the hole and spool. All sizes are measured with expensive Japanese measuring sets.

• Assembling the hydraulic distributor, installing new seals, checking the smoothness and evenness of the spools. Inspection and pressing of hydraulic distribution on a hydraulic stand. Adjusting the hydraulic distributor to the required pressure in the system. Check for leaks in the hydraulic distributor.

A precisely manufactured, hardened and polished spool is one of the factors of durability and performance of a repaired hydraulic distributor.
