Where is spindle oil mainly used? What are the types of spindle oils?

The spindle oil will not be stained and discolored for a long time, prolong the service life of mechanical equipment, eliminate the need for frequent oil change and maintenance equipment, and reduce maintenance costs. And it has the following characteristics:

1. Lubricity:

The spindle oil contains a variety of anti-wear and anti-wear additives, although the viscosity is low, it can still form effective lubrication on the surface of each part of the spindle, which can effectively protect it from wear. The good oxidation resistance makes it do not produce sediment in the closed circulation system, which eliminates the resulting wear on the spindle and bearing, and ensures the consistent accuracy of the equipment.

2. Rust resistance:

Spindle oil has good rust and corrosion resistance, which can effectively inhibit the corrosion caused by water invasion to equipment.

3. Cooling:

The spindle oil used in the operation of the equipment has excellent heat dissipation performance, which can quickly remove the heat generated by the spindle due to ultra-high speed operation.

4. Cleanliness:

To ensure the machining accuracy of the machine tool, the spindle oil will not form sludge and sediment even if it runs for a long time 24 hours under harsh conditions, so as to eliminate the wear of the spindle caused by this, and has good dissolution and flushing ability. This feature is essential for the spindle --- the heart of precision machine tools, ensuring that the machine is consistently accurate and provides the best possible machining accuracy.

Spindle oil is a special lubricating oil for spindle bearings of precision machine tools and similar equipment, which plays a very important role in ensuring the working accuracy and performance of the spindle and prolonging its service life, also known as bearing oil.

The machining precision of precision cutting machine tools is related to the accuracy of the guide rail assembly and the level of the tool, and to a large extent depends on the operation accuracy of the spindle. The gap between the spindle and the main bearing is very small, generally, the speed is between 1000 and 300r, and the bearings used for the spindle are all sliding bearings. Some of its oil supply methods are circulating type, and some are oil bath type.

The performance requirements of spindle oil are as follows:

1) Appropriate viscosity and good viscosity and temperature performance The gap between the spindle and the bearing is very small, and the viscosity of the oil must be very low to enter the gap to establish the oil film to play the role of lubrication and anti-wear, and the oil temperature should rise during the spindle oil operation, and the viscosity change of the oil in the oil temperature should be as small as possible.

2) Good lubricity and certain anti-wear The oil film of low-viscosity oil is thin, and the parts with small gaps tell that the oil film is easy to break when rotating, because the spindle oil should maintain a good oil film, that is, it must have good lubricity and certain wear resistance to reduce the temperature rise.

3) Anti-oxidation, anti-rust and anti-foaming This is the general requirement of general lubricating oil.

4) Because the oil will inevitably be mixed with the condensed water or machine tool coolant in the air during the working process of the spindle lubrication system, the oil is required to have good rust resistance.

Spindle oil is a grade rather than a model, and is usually divided into grades and so on according to 40 kinematic viscosity.

Grade 2: The kinematic viscosity is 99°C with a flash point (closed) and a freezing point of -18°C.

Grade: 5: kinematic viscosity is, flash point (closed) is 112 °C, and freezing point is -19 °C.

Grade 7: kinematic viscosity is 128°C with a flash point (opening) and a freezing point of -26°C.

Grade 10: The kinematic viscosity is 170°C and the freezing point is -26°C.

Grade 15: kinematic viscosity of 160°C and freezing point of -24°C with kinematic viscosity of 160°C (opening).

The door shaft can be fully synthetic lubricating grease, because it is colorless and odorless, has good adhesion and durability, and is environmentally friendly food grade.

When using, just raise the door slightly and apply it to the local body, or apply it directly to the copper hinge.

The gap will naturally penetrate into it slowly, so you don't have to worry about the door shaft being inflexible.

Try not to use the door shaft in a humid environment, so as to prolong its service life and save a certain cost.

The spindle oil is divided into equal grades according to the kinematic viscosity of 40;

First of all, good lubrication effect can reduce the working temperature of the bearing and prolong the service life; To this end, it should be noted in operation and use: at low speed, grease and oil circulation lubrication should be used; At high speeds, oil mist and oil vapor lubrication are adopted. However, when using grease lubrication, the sealing amount of the spindle bearing is usually 10 of the bearing space volume, and it must not be filled at will, because too much grease will aggravate the heating of the spindle.

For oil circulation lubrication, in the operation and use, it is necessary to check the spindle lubrication constant temperature oil tank every day to see whether the oil volume is sufficient, if the oil volume is not enough, the lubricating oil should be added in time; At the same time, it is necessary to pay attention to check whether the temperature range of the lubricating oil is appropriate.

The function of the top shaft oil pump of the steam turbine is to prevent damage to the steam turbine and reduce the cranking power of the steam turbine.

The oil source of the top shaft oil pump comes from the lubricating oil behind the oil cooler, and the pressure is about that, which can effectively prevent the oil from absorbing air erosion by the pump. The oil is coarsely filtered through a 32 m automatic backwash filtration unit.

Then it enters the suction port of the top shaft oil pump through the 25 m double-barrel filter, and after the oil pump is pressurized, the oil pressure at the outlet of the oil pump is, and the pressure oil enters the diverter through the single-cylinder high-pressure filter.

The branch mill is passed through a one-way valve.

throttle valves, and finally into the bearings.

By adjusting the throttle valve, the amount of oil and oil pressure entering each bearing can be controlled, so that the jacking height of the journal is within a reasonable range (theoretical calculation, the jacking oil pressure of the journal is 12 16MPa, and the jacking height is greater than that. The oil pressure at the outlet of the pump is by the relief valve.

Modulation. In order to control the operation of the two pumps, switch and prevent damage to the pump's suction and venting, a pressure switch is installed on the inlet and outlet pipelines of the oil pump.

When the oil pressure at the inlet of the oil pump, the pressure switch at the inlet of the oil pump is turned on (on), indicating that the suction filter screen is blocked; When the oil pressure of the outlet pipeline of the pump is on, the pressure switch on the outlet pipeline is turned on (on), and the standby top shaft oil pump should be started.

Be. Spindle oil, spindle oil is low-viscosity spindle bearing oil (commonly known as spindle oil), the new industry standard classifies spindle oil into bearing oil (reference standard: SH T 0017-90), which belongs to anti-oxidation, anti-rust and anti-wear oil. The spindle oil is made of highly refined base mineral oil and added a variety of high-efficiency additives such as cleaning, dispersion, anti-wear, anti-oxidation, anti-corrosion, anti-foaming, etc.

Spindle oil is specified for equipment maintenance by machine tool manufacturers.

The lathe headstock uses spindle oil.

Spindle oil is suitable for textile machines, worsted spindles, spindles of automatic machine tools and light-load hydraulic circulation systems, light-load high-speed industrial textile bearings, industrial circulation systems, etc.

You can use No. 46 engine oil, No. 32 engine oil and hydraulic oil, diesel must not be added, add your gears, sliders and bearings can not be lubricated and will be scrapped soon.

Ordinary mechanical oil can be used without adding hydraulic oil, and it is not hydraulic, and you can add hydraulic oil if it is not good for gears or something.

No. 46 engine oil, you can also add hydraulic oil, no big problem.

Engine oil, that is, engine lubricating oil, is known as the "blood" of the car, which can lubricate, clean, cool, seal, reduce wear, prevent rust and corrosion of the engine. The engine is the heart of the car, and there are many metal surfaces in the engine that rub against each other, and these parts move fast, the environment is poor, and the operating temperature can reach 400°C to 600°C. Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life.
