Mining machinery maintenance

Mining machinery is a large-scale equipment. The purchase of new equipment and the frequent replacement of parts and components will consume a lot of money and affect the production progress of the company. Therefore, how to properly maintain and maintain the mine equipment to extend the service life of the equipment is very important.

1. Mechanical equipment should avoid collisions to ensure complete and reliable parts and good system coordination.

2, to ensure that the equipment is clean and reduce all kinds of corrosion.

Corrosion occurs when the metal surface is chemically or electrochemically affected by the surrounding medium and is destroyed. This corrosion will not only affect the normal operation of the mechanical appearance equipment, but also will corrode the parts inside the machinery. Such as rain, chemical substances in the air through the mechanical parts of the external channels, cracks, etc. into the machinery, corrosion of mechanical parts inside, accelerate mechanical wear and increase mechanical failure. Because this kind of corrosive effect is sometimes invisible and intangible, it is easily overlooked and therefore more harmful.

In use, management and operations personnel should take effective measures to reduce the impact of chemical corrosion on machinery in light of local weather conditions and air pollution at that time, and the key is to prevent rain and chemical components in the air from intruding into the machinery. Working in the rain.

3. Bearing maintenance The mining machinery shaft bears the full load of the equipment. A good lubricant has a great bearing on the bearing life. It directly affects the service life and operating rate of the machine. Therefore, the injected lubricant must be clean and sealed. Must be good.

4, regular inspections, tightening, necessary maintenance.

Marine Electro-hydraulic Windlass

The windlass is installed on the main deck of the ship's bow, which is used for the ship to lift the anchor and drop the mooring cable.
Windlass can be divided into manual, electric, hydraulic, pneumatic, etc. according to the driving form.

The windlass can be divided into several specifications such as φ12--φ120mm according to the diameter of the anchor chain.
Windlass can be divided into single-sided and double-sided according to the distribution of drums.
The windlass is mainly composed of base, bracket, chain wheel, brake, chain wheel, gearbox, electric control system (except manual windlass), etc. Electric windlasses have electric motors, and hydraulic windlasses have hydraulic pump stations.
The main technical indicators of the windlass include the diameter of the anchor chain, the nominal speed of the anchor, the rated load, the supporting load, several levels of speed change, electrical system, etc. The installation of the windlass on the ship should ensure that the wrap angle between the anchor chain and the sprocket is 117-120°.
Electric windlass
The electric motor directly drives the windlass, and the drive shaft is driven by the gear box to work, and the structure is simple; it is generally suitable for windlasses with an anchor chain diameter of 16mm-93mm.
hydraulic windlass
It is suitable for windlass with anchor chain diameter of 16mm-120mm. Hydraulic windlasses are also called electro-hydraulic windlasses. It drives the oil pump with a motor, drives the motor with high-pressure oil, and then drives the transmission gear through a reducer (or no reducer). To make the windlass run, its structure is relatively compact and its volume is small. Now there has been an automatic hydraulic windlass, which is equipped with an anchor chain length sensor. When the anchor chain needs to be thrown out, the windlass will automatically stop; , can automatically decelerate; the anchor will automatically stop when it enters the anchor chain drum and is properly received.
