Greaser is a fairly important product that is actively used in the production of equipment, special machines and cars. Its main purpose is to supply oil and prevent friction in the joints without disassembling the structure. Read more about the above product.
Lubricator - what is it?
The above product is a part that is part of the pump design. Also, a grease fitting is an addition to bearings, which are characterized by the use of grease or special oil.
In its configuration, the above part is a check valve. It is installed on the lubrication channel of the pump. Also, this valve can be mounted in the bearing cover. With the help of a grease fitting, oil is supplied for lubrication to friction units, which are located in rather hard-to-reach places. It is no longer necessary to disassemble the structure for this.
The above product consists of the following parts:
- spring;
- case;
- steel ball.
The last one doesvalve role. It blocks the channel or passes lubricant. Experts note that the above product also protects the lubrication channels of the equipment from clogging.
Kinds of the above items
Domestic manufacturers offer the following types of products on the market for similar parts:
- Angle grease fitting (angle of inclination between threaded and filling ends is 45 and 90 degrees);
- threaded straight product;
- Greaser smooth straight for pressing in.
European manufacturers have some other classification of these products. They also produce three types (A, B, C). In addition, their angular grease fitting is divided into two separate types: "B" - the angle of inclination between the threaded and filling ends, is 45 degrees, and "C" - this figure is 90 degrees.
The screw-in part of the above product has a conical thread. This is done to seal the threaded connection.
Specialists note that the above products may differ in the diameter of the screwed part.
Some manufacturers put a special anti-corrosion coating on grease fittings: zinc or cadmium. It should be noted that the above products are made from the following materials: brass, stainless steel or plain steel.
Grease pots - what is it?
Grease fittings, which are designed to supply the thickest grease, are named above. By using a syringe with a speci althe tip injects grease into the grease fitting.
The head of the latter can have a different diameter: 22, 16 or 10 mm. Accordingly, the tip for the oil syringe is selected according to the above dimensions.
Grease makers are made from stainless steel or brass. Then, to ensure reliable anti-corrosion properties, a special zinc coating is applied to it.
The working principle of the above product
When refueling grease, use a special syringe. For a grease fitting, a lever or rod type is more suitable. Under the pressure of the lubricant, the ball of the above product removes the spring. The result of this is the opening of the lubrication channel, into which lubricants must be passed.
It should be noted that syringes from some manufacturers are equipped with a convenient plunger handle lock. The latter is designed for filling the syringe manually. A special wear-resistant powder coating is applied to the syringe body.
After filling, the spring straightens out, and the ball returns to its original position. About 20,000 cycles is the minimum life of the above product.
The grease nipple is an important part that is widely used in the engineering and automotive industries.
