The importance of sealing system and packing performance in hydrocon crusher
The crushing system in Hydrocon is adjusted by the up and down of the main shaft and by the force of the hydraulic jack on the bottom of the machine. High pressure oil enters the chamber under the jack piston and keeps the shaft in the optimal position according to the desired grain size. In this high-pressure environment and contaminated with dust, oil deposits in the lower part of the device
Observation of oil stains in the lower compartment of the hydrocon chassis or oil overflow from the hydraulic guide jack is a confirmation of the destruction of the seals and packings, which requires immediate intervention and part replacement.
Abnormal increase in hydraulic oil temperature
The internal escape of oil from the side of worn packing causes local cavitation phenomenon and strong liquid friction, which leads to extreme heating of the hydraulic tank and reduction of oil lubrication properties.
Necessary tools and supplies for how to replace the hydrocon packing
Before starting the packing replacement operation, it is necessary to prepare the environment and have industrial tools. Failure to use standard tools may scratch the inner wall of the jack cylinder.
Step-by-step steps on how to replace hydrocon packing in Iran Sanat complex
The steps of how to replace the hydrocon packing require compliance with the engineering order and industrial safety points. Iran Sanat stone crusher technicians carry out this process according to the following specialized checklists.
First step: Unloading, cutting off energy and securing the environment
First, the entry of any cargo into the crushing chamber must be stopped and the machine must be completely emptied of stones and minerals. After turning off the main electric motor of the stone crusher and the pump of the hydraulic unit, completely disconnect the main electrical panel and install the safety label. Also, the pressure trapped in the accumulators and hydraulic lines should reach zero by opening the manual pressure relief valve.
The second step: Draining the hydraulic oil of the jack cylinder
Close the jack circuit blocking valves and slowly open the hydraulic connections connected to the bottom of the hydrocon jack. Drain the hydraulic oil inside the cylinder in sanitary tanks. Iran Sanat crusher technicians emphasize that you check the drained oil for the presence of metal shavings and abrasive particles to ensure the health of the bushings and bearings.
Third step: Dismantling the bottom cover and jack accessories
Open the screws holding the cylinder cover of the hydrocon jack using a standard box wrench in a cross pattern. Lower the cover slowly with the help of a tipor or a workshop crane and place it on the workshop stand. Secure the jack piston and guide shaft in a completely stable position to prevent them from falling suddenly.
The fourth step: removing worn-out packings and cleaning the seat
Using brass or soft plastic hooks, remove the worn hydrocon packing, O-rings and back-up rings from the corresponding grooves. Never use sharp steel screwdrivers for this, as the slightest scratch on the grooves will cause a permanent oil leak. Wash all seats, grooves and piston wall with standard solvent and dry with compressed air.
Fifth step: checking tolerances, bushings and technical inspection of surfaces
Before installing a new packing, it is vital to inspect the surface of the piston and the inner wall of the cylinder. If there are any creases, splits, or deep corrosion, the cylinder needs to be carefully turned or ground. Iran Sanat stone crusher group, having the precision heavy turning machinery, offers full restoration services of hydrocon jack cylinder and piston with the highest metallurgical quality.
Sixth step: lubrication and placement of new hydrocon packings
Seventh step: reassembly, tightening the screws with standard torque and venting the circuit
Put the jack cover in place and tighten the screws symmetrically and crosswise with a standard torque meter. Connect the high pressure hoses and fill the unit tank with clean oil. After starting the hydraulic pump at low speed, open the air vent screw on the jack block to completely release the air trapped in the cylinder, then block and seal it.
Key tips to increase the life of packing and hydrocon jack
In order to maximize the life of hydrocon packing and reduce line downtime costs, it is necessary to observe several principles of preventive maintenance:
First, continuous monitoring of hydraulic oil quality and temperature. Hydraulic oil should not exceed 60 degrees Celsius in working conditions. High heat makes the polymer structure of the packing brittle and brittle.
Second, timely replacement of the filters of the suction line and the return of the hydraulic unit. Micron particles suspended in oil can destroy sealing grooves.
Fourth, the use of high-quality dust protectors on the main shaft and the lower part so that the dust from sand washing does not enter the piston chamber.
