Grease Centralized Lubrication Equipment

Centralized lubrication equipment has obvious advantages, because the pressure enough for the amount of oil, so you can ensure that the large number of widely distributed lubrication points receive timely lubrication, the friction of the friction pair tropical walk; the friction surface of the metal abrasive mechanical impurities as the oil flow and circulation impurities away and rinse to achieve good lubrication, reduce friction, reduce wear and reduce the consumption of wearing parts, to reduce power consumption, extend equipment life purpose. But the centralized lubrication equipment maintenance and management is more complex, the adjustment more difficult. Every aspect of the problem may cause the failure of the lubrication equipment, or even stop, So also in the future production practice continue to be improved. In the lubrication equipment, the installation of a variety of lubrication equipment and devices, a variety of control devices and instruments, to regulate and control the flow of the lubricating system, pressure, temperature, impurities filtration equipment lubrication is more reasonable. In order to make the entire system safe and reliable, should have the following automatic control and signal devices.

1. Main system control

Must first start the host before the start of the lubricating oil pump, the fuel supply to the host. When the oil pressure normal to start the host. If after the start of the lubricating oil pump, oil pressure fluctuations or oil do not increase, then the lubrication equipment is not normal. At this time, even if the operation is press the button and host can not rotate, this was a necessary security protection measures. Interlock control method commonly used in the pressure tubing on the road to install the hydraulic relay, the control of the electrical circuit of the host operating.

2. Automatically start the pump

In the lubrication equipment, if the system oil pressure dropped to below the working pressure (0.05MPa), when the standby pump start, and start at the same time issued a warning signal, red light, electric whistle, when on duty according to the warning signal immediately inspect and take measures to eliminate the fault. To be the normal system hydraulic standby pump to stop working.

3. Forced to stop the host is running

After the start of the standby pump, the hydraulic system still continued to decline (less than the working pressure) (0.08 ~1.25MPa) the pump automatically stops running and send a signal; forcing the host to stop running, and also issued an accident alert signal, the red light. electric whistle.

4. High-voltage signal

When the system pressure exceeds the normal working pressure 0.05MPa, it is necessary to issue high-voltage signal, the green light, electric whistle. On duty should immediately check and eliminate the fault. Start the standby pump, forcing the host stall, often is used to control the electrical contact pressure gauge and pressure relay.

5. Tank oil level control

The oil tank control is often used with reed float level controller. When the oil tank planes continue to decline to a minimum to allow the oil level when the liquid level controller contact closure, the issue of low level warning signal, the red light, electric whistle, while forcing the pump and the host to stop the run. When the oil tank level continuously increased (which may be water or other media into the tank), the highest oil level surface, the issue of high level warning signal, red light, electric whistle, you should immediately check the adopted restrictive measures to eliminate the fault.

6. Tank heating control

In cold regions or winter operation, the lubricating oil in the tank should be heated, the oil temperature is generally maintained at about 40 ° C, in order to maintain the flow of oil, otherwise the whole system of control difficulties due to the low temperature increase in the viscosity of the oil . There are two ways heating, a steam heating, more relaxed; the other is heated by electric heating elements. Heating mode of the latter is the more violent and sometimes make the oil thermal cracking reactions, reducing viscosity and generate glial precipitation. Both are equipped with the device automatically adjust the temperature, when the oil temperature to rise to the specified temperature, that is, automatic power off steam.

7. The system automatically temperature measuring device

The relevant parts of the temperature in the system in operation should the timing measurements in order to master the operation. Such as fuel tank, drain line into the cooler oil temperature and water temperature should be at any time measurement. To this end, the use of automatic temperature measuring device, commonly used measurement device is a thermal component and bridge thermometer, just a twist on the operation panel switch, you can measure the temperature of various parts.

8. Filter automatically start

When the oil flow in and out of the filter pressure is greater than 0.05 ~ 0.06MPa, the filter is blocked. Should start automatically filter to remove the disc filter cartridge around the impurities. Usually electric contact with a differential pressure gauge to control when the pressure decreases (or restored to allow pressure range), cut off the power automatically stop the cartridge clear scratch.

The grease centralized lubrication are also included in the following two lubrication equipment:

1. Rotary piston pump oil centralized lubrication equipment

2. Gear pump oil circulation lubrication equipment
