Industrial hydraulics repair. Hydraulic equipment repair

Auto repair shops use various power equipment, which is based on hydraulics, or more precisely a hydraulic cylinder and a hydraulic pump. Hydraulic cylinders are available in direct and reverse action. In direct-acting cylinders, the rod comes out of the cylinder under the action of hydraulic fluid, while in reverse-acting cylinders, on the contrary, it is pulled into the cylinder. Pumps are most often found in three types: manual, pneumohydraulic, electrohydraulic. In hand pumps, pressure is generated by the force applied to the handle and transmitted to the plunger.

In pneumatic-hydraulic pumps, the force is transmitted to the plunger due to the reciprocating movement of the air motor. Electro-hydraulic pumps are most often used in car lifts, sometimes in presses and tire changers. and are more productive than those listed above. As a rule, they consist of an electric motor with a power of 2-3 kW, a valve block, and a gear pump, which creates pressure in the hydraulic system. An integral part of any hydraulic system are high-pressure hoses through which oil flows from the pump to the cylinder

Main types of hydraulic equipment malfunctions.

1 Failure of the hydraulic cylinder hose. This is the simplest malfunction that occurs due to aging of the hose, or increased pressure in the system, or as a result of mechanical stress. Eliminated by replacing the hose with a new one.

2 Hydraulic cylinder malfunction. Most often it manifests itself in the form of a hydraulic cylinder leaking through seals (rubber and polyurethane rings or cuffs). A leak can be caused by various reasons: wear of seals, wear or mechanical damage to the rod, wear or damage to the piston, corrosion of the hydraulic cylinder.

3 Hand pumps are used mainly in presses, body hydraulics, and traverses of four-post lifts. The most common malfunctions are: leakage of the plunger pair, leakage, malfunction of the bypass valve.

4 Pneumatic hydraulic pumps are used in power body hydraulics, traverses, and presses. Among the malfunctions there are problems with both the pneumatic and hydraulic parts. Among the pumps of this system, cases of non-repairability or unprofitability of repair most often occur.

5 Electro-hydraulic pumps have found very wide application. Relatively often, the electric motor, pump coupling, gear pump, and drain valve fail in them.

Our works

The functioning of any hydraulic unit largely depends on the current state of the hydraulic cylinder. This unit is fundamental to the operation of any hydraulic system. During operation, the hydraulic cylinder inevitably wears out and requires repair. Also, during operation, it is necessary to regularly service this unit.

You can independently determine the time when the hydraulic cylinder fails or requires service according to the following characteristics:

IN hydraulic system or in some parts there is a sudden drop in pressure and oil level;
There is a sharp, unpleasant odor characteristic of hydraulic fluid;
In operation or even at rest, you observe a fluid leak from the hydraulic system.

The company GIDROTEMA LLC specializes in the repair of hydraulic cylinders in Moscow and the Moscow region. Products from such manufacturers as: , .

Urgent repair of hydraulic cylinders is an urgent need for those industries that use hydraulic drives. Such equipment is used in special equipment operating in the construction, road-building industries, mining, processing and transport enterprises. Among the mechanisms that need restoration are car transporters, asphalt pavers and truck cranes, forklifts and concrete pumps, bunker trucks and tail lifts, loader cranes and garbage trucks, tractors, excavators and the most different types agricultural machinery.

The company "GIDROTEMA" LLC carries out restoration of telescopic devices with the following parameters: diameter - up to 2000 mm, rod length - up to 16000 mm.

The procedure for repairing hydraulic cylinders in Moscow and the region

Professionals from Gidrotema with extensive experience are able to perform accurate diagnostics, select the necessary spare parts and bring to life the failed mechanism. In this case, the customer receives not only high-quality work, but also a reasoned cost calculation, post-repair testing on a test bench and advice on the further operation of hydraulic equipment.

The accuracy of price calculations is due to professionally performed diagnostics and troubleshooting of equipment. Depending on the degree of wear of parts and components, the complexity of the damage, the range of measures for repairing hydraulic cylinders includes the following operations:

dismantling of hydraulic equipment and detailed disassembly;
inspection, diagnostics and defect detection;
cleaning surfaces from lubricants and other dirt;
replacement of defective, obsolete and unsuitable pistons, rods, liners;
checking and replacing seals;
surface restoration;
production of turning and welding works;
assembly and installation of hydraulic cylinder;
performance check and technical characteristics on the test bench.

Only imported products and blanks are used as spare parts, assemblies and blocks: delivery is carried out from Romania and Italy.

Repair deadlines:

defect detection – 1-2 days from the moment the order is received;
placing a work order and preparing a cost estimate taking into account the cost of work and replacement parts – 4 hours;
The total time to restore the product is from 1 day.
