5. Precautions
(1) If an LPG leak is found when the forklift truck is in use, the LPG switch should be turned off; the
hydraulic valve should be closed; the pipe joints of device units and fasteners should be checked for
looseness or leakage and promptly dealt with. The truck should be driven using gasoline if the faults
are not eliminated.
(2) Gasoline 93# or vehicle LPG should be used for dual
-
fuel vehicles; otherwise, the accuracy of
ignition timing will be affected, affecting performance.
(3) When the parking time is more than 10min, the LPG switch (or hydraulic valve) should be closed.
(4) When the engine is running, the water temperature should be 70
℃
-
85
℃
.
6. Pressure reducing regulator
The pressure reducing regulator has two functions: I. Pressure reducing function. It can reduce the
LPG pressure of the steel cylinder to barometric pressure; II. Evaporation function. LPG can be
vaporized by absorbing the heat circulating in the engine.
7. Mixer
According to the running condition of the engine, the mixer sends the vaporized LPG mixed with air
into the engine to meet the requirements of the engine under various working conditions.
8. Steel cylinder
(1) Functions
It consists of a safety valve, LPG inlet, quick coupler of outlet section, and corresponding fittings, it is
the fuel storage supply system for LPG forklift trucks and is installed at the rear. Main functions are:
a. Stop valve
Hand valve to control inlet and outlet pipes.
b. Filling limit valve
Automatically closed when the LPG quantity reaches 70%
-
80% of the steel cylinder capacity.
c. Liquid level display
Can directly display the liquid level in the steel cylinder.
d. Flow limit valve
Automatically closed when the flow rate is too high (system damage and flow rate exceeding the
design value).
e. Safety valve
When the cylinder pressure exceeds the specified pressure, the safety valve automatically opens
the pressure relief to prevent accidents.
(2) Main parameters
Working temperature:
-
40
℃
~+60
℃
; working pressure: 2.2MPa; opening pressure of safety valve: 2.5
MPa ± 0.2MPa; maximum filling volume: 80% of steel cylinder volume.
(3) Replacement of steel cylinder
Affix the operating instructions for safe use on the steel cylinder (see Fig. 1)
1. Park the truck on the flat and solid road, shut down the engine and pull up the hand brake.
2. Remove the steel cylinder:
