WGXYZA High low oil station is a oil lubrication deice combined of two parts ; high pressure part is 31.5MPa ,oil output 25L/min; and low pressure part is 0.4MPa ,oil output 16～125 L/min .This station holds units of filter, heater ,cooler etc. and function of safety , auto controller ,alarm etc .It is suitable for oil lubrication system of large scale equipment to lubricate hybrid bearing installed on the miller, rolling machine or electric the machine .Its working medium is industrial oil of N22～N320.According to the principle of dynamic and static pressure ,it uses the high system when the machine in starting , stopping or slow running ; uses the low system when running ordinary , to ensure the lubrication reliable on various speedy of large main machine ,and to prolong its life
Example of order:
A high-low oil station its high pressure is 31.5MPa, output 2.5L/min ,and low pressure is 0.4MPa, output 25L/min
WGXYZ－25A high low oil station
Structure & Principle
This station is consisted mainly of oil tanker (magnetic core mesh filter inner),low pressure pump device ,high pressure pump device ,twin barrel magnetic core mesh filter , heater ,cooler ,manual high pump , pipeline ,valve ,instrument panel ,electric controller etc .
Before starting main machine ,starts the low pump ,when its low filling pressure reached normal ,stars the high pump which suction port is connected to the pipeline of low pump. The high oil through high check valve flows to the static pressure bearing .When the high pressure reached a curtain value ,starts the main machine ,slow runs or stops. After main machine running normally then stops the high pump (exception the low running ),but the low pump must operate ordinary . The low pump suction oil from tanker ,then sends it pass check valve ,twin barrel mesh filter , cooler to the static pressure bearing too ,to maintain the main machine running ordinary .After stopped main machine ,if want filling oil by high or low pump timely ,can control by time relay to lubricate the point interrupt.
The specific value of high or low pressure is controlled by high-low safety valve in the system.
In the ordinary running of main machine , one low pump is working ,and another one is standing by . As the system pressure down at a value wanted , starts the ready pump , and then stops it while normal . If the pressure downing on still ,must sent an alarm ,and consider stopping the main machine.
When the high plunger pump at fault , can fills oil by manual pump.
Set the filter before the cooler , make the low viscidity oil passes the filter earlier , one filter at working , and another one at standing by , controlled by handle switch valve.
Oil level higher or lower than a limit , are sent alarm by level signal , manual oil filling or stopping .
Back oil passes the magnet mesh filter prepared in the tanker ,and can absorb the iron particulate at same time.
Whole set of oil station is matched an instrument panel and an electric controller , to display operating data and to carry out at automatic , manual or alarm.
A bimetallic electric contact thermometer installed on the tanker , when oil temp is too low sends a signal ,to open the heater by handle ,and stops automatically when reached an appointed temperature.
A electric contact pressure type thermometer installed in the filling port , setting two limits of maximum and minimum temp needed ,to determine the cooler working or not.
