KJ, KM, KL Series Single-Line Progressive Distributors (7-21 MPa)

I. Overview

KJ, KM, KL series single-line progressive distributors, suitable for systems with dense lubrication points, varying oil consumption, and frequent oiling in a single-line concentrated lubrication system. They are used to form a parent-child distribution system for zone control and lubrication.

The KJ, KM, KL series single-line progressive distributors are composed of a supply body, end body, and intermediate bodies (3-8 pieces, depending on design requirements) made of medium-carbon alloy structural steel. The normal outlet of the distributor is set on both sides, with auxiliary outlets also provided. Non-return valves are installed inside the oil outlets of each intermediate body, effectively preventing the backflow of grease due to the back pressure of the lubrication points, ensuring the precise and quantitative supply of grease to each outlet.

II. Technical Specifications

Applicable to greases with a penetration not less than 265 (25°C, 150g) 1/10mm or lubricating oils with a viscosity grade greater than N120:

Operating temperature range: -10℃ to 80℃.

III. Operation Description

1. The lubricant, pressurized by the lubrication pump, flows into the supply port and moves the pistons A, B, and C according to the arrow direction in the diagram. At this point, the left chambers of pistons A and B remain stationary in the right position due to the oil pressure, while the right chamber of piston C receives pressure, causing the oil to start moving to the left.

2. The incoming lubricant pushes piston C to the left, forcing lubricant in the left chamber towards the NO.1 outlet through external piping to the lubrication point. When piston C reaches the left limit, lubricant begins to enter the right chamber of piston B.

3. The incoming lubricant pushes piston B to the left, forcing lubricant in the left chamber towards the NO.2 exhaust outlet through external piping to the lubrication point. When piston B reaches its left limit, lubricant begins to enter the right chamber of piston A.

4. The incoming lubricant pushes piston A to the left, forcing lubricant in the left chamber towards the No.3 exhaust outlet, which is then sent to the lubrication point through external piping. When piston A reaches its left limit, lubricant begins to enter the right chamber of piston C.

5. The incoming lubricant pushes piston C to the right, forcing lubricant in the right chamber towards the NO.4 exhaust outlet through external piping to the lubrication point. As piston C moves to the right limit, lubricant begins to enter the left chamber of piston B.

6. The incoming lubricant drives piston B to the right, pushing lubricant from the right chamber towards the NO.5 outlet. It is then sent to the lubrication point through external piping. As piston B moves to its rightmost limit, lubricant begins to enter the left chamber of piston A.

7. Inflowing lubricant drives piston A to the right, pushing lubricant in the right chamber towards the No.6 outlet. It is then sent to the lubrication point through external piping. When piston A reaches the right limit, it returns to the initial state 1 and continues to repeat the above action.

Six. Overpressure Indicator

Mounted on the distributor's preparatory outlet, the indicator slightly protrudes outward when the pressure rises above the specified value due to a lubrication point or pipeline blockage. Through the fault signal emitted by the system, the blocked section can be directly located by checking if the indicator has protruded on-site.

Section 7: Overflow Indicator

Installed on the outlets of all distributors at locations prone to blockages in harsh environments, when a lubrication point or pipeline becomes blocked, the pressure abnormally rises above the specified value. The lubricant supplied to the blocked point of the distributor overflows out through the overflow port. Upon inspection, the overflow point indicates the blocked fault location.

Only applicable to continuous operation sections; not to interfere with the operation of other distributors.
