Metering devices

Progressive metering device

The progressive distributor supplies grease to each lubrication point progressively through its corresponding plunger piston. Progressive distributor can be divided into block distributor and plate distributor according to the different structures.

The block distributor LR-SSV/SSVA/SSVD is an integral block-type structure. The block distributor features high working pressure, which can be applied to the machinery equipment with heavy load.

The plate distributor LR-VPKA/VPKB is composed of a top chip, a bottom chip and several middle chips (can choose from 2 to 8 pieces), with two outlets on each middle chip. The grease pump capacity of each outlet, which is determined by the sectional area and stroke of the plunger piston, can be designed individually.

Feature:

  • Adopt new design, progressive system is equipped with pressure gauge to detect the system pressure.
  • Set system warning pressure and alarm pressure, considering the factors of resistance, low temperature, grease and others.
  • Fault early warning when the system is not completely blocked; Fault alarm when the system is blocked
  • With fault early warning system, it is possible to maintain the warning dispenser during maintenance period, thus improving the working life of the system.

Single Line metering device

Single line grease distributor is made up of separate chips. Chips number could range 1 to 10 according to program. Single line lubrication distributor consists of distributor chips, piston, spring, metering chamber, quantitative connector, indicating arm, two position three-way valve.

Feature:

  • The pioneering single line distributor is easy to be installed and expanded.
  • Each lubrication branch in one distributor group works independently and each other is not affected.
  • It can avoid the grease block with stable performance, long service life, easy and cheap for maintenance.

Dual Line metering device

The Dual Line LI-DLA type metering device is a sectional metering device. Its metering sections cover a metering volume per outlet and cycle of 0,10 ml to 1,00 ml. All sections (inlet, intermediate, end) are tightened via tie rods. The delivery ducts are sealed by porting plates in-between the segments. A minimum of ONE intermediate sections is possible.

For each cycle of the indicator rod corresponds to the combined outlet, and the displacement of each cycle is the sum of the output of the combined outlet. The allowable deviation of all outlet discharge is ±10%.

Feature:

  • The pioneering dual line distributor is easy to be installed and expanded.
  • Each lubrication branch in one distributor group works independently and each other is not affected.
  • It can avoid the grease block with stable performance, long service life, easy and cheap for maintenance.

Pressurized Single Line metering device

Pressurized Distributor consists of distributor body, valve mushroom, pistons, center port, return spring, fuel discharge port, jointing and others. While the pump module pressurize the mainline, pressure build-up from a pressurization distributer forces a piston forward, and delivers a preset volumes of grease to each lube points. The discharge pressure can be up to 2.5 MPa.

At freezing temperatures, discharge pressure will be improved as the temperate drop in order to make grease conveyed to friction pairs. When the pump module is de-energized, the internal vent vents, and the injectors can prime themselves in preparation for the next cycle. According to the volumes of grease that friction pairs require, pressurization distributers are available in three discharge volumes:0.1ml,0.2ml and 0.4 ml per pump cycle.

Feature:

  • Stable performance and convenient maintenance.
  • Furthermore each lubrication branch in one distributor group works independently and each other is not affected.
