The system is under the position of "AUTO", pressure switch allows the pressure of accumulator bank being
always kept in 19 ~ 21 MPa (2700 ~ 3000 psi), available for opening and closing preventer all the time.
)
CAUTION: When main switch is under "AUTO" position, electric-operated oil pump will start to work
automatically. The operator must pay attention to avoid being hurt by the motor.
When the main switch is turned to "MANUAL" position, press "START" button, electric-operated oil pump will
start to work. When system pressure goes up to 21 MPa (3000 psi), the "STOP" button should be pressed to
stop the pump.
CAUTION: When main switch is under "MANUAL" position, electric-operated oil pump cannot stop
automatically. The operator should cautlously observe system pressure, and manually stop the
electric-operated pump when required.
5.2 Control principles of Hydraulic System
See attached diagram for the principles of hydraulic system of control system of surface mounted BOP stacks.
The pressure oil In the accumulators goes through the Isolate valve (hig h-pressure ball valve) of the
accumulator bank, the filter, and the reducing 3-posltion 4-way control valve. In the meantime, the pressure oil
goes from the accumulators. through the filter, into the reducing and regulating valve, which controls the annular
preventer. By puching the handle of the control valves you can "OPEN" or "CLOSE" the preventer.
The control valve may be operated through the driller's panel. First, turn on the air supply valve to the "OPEN"
position, wh ich controls th e air supply operation on the driller's panel , and then turn on the re lated air valves to
operate the control valve. Then , compressed air goes to the remote control panel through the air cable, into

relevant air cylinder, push the handle of the control valve to change d1rectlon. Whlle the air valve changes
direction on the driller's panel, compressed air pushes the piston of the display cylinder, and you will see the
letters of "OPEN" or ''CLOSE'' from the hole on the top of each air valve on the driller's panel.
The letters of "OPEN" or "CLOSE" indicate the preventer is in the "OPEN" or "CLOSE" position.
CAUTION: On the driller's panel, the valve was operated in a 2-step mode. Before turning the valve of
each control object, you must turn the air supple valve to open simultaneously. Due to long pipeline
of control system, turn the valve and hold it for more than 3 seconds, in order to guarantee the
proper direction change of the valve on the remote control panel.
The adjustment of the outlet pressure of the reducing and regulating valve in the control manifold ranges from
0 to 14 MPa (2000 psi) , with 10.5 MPa (1500 psi) being most often used. When the bypass valve is in ''OPEN "
position , the reducing and regulating valve will not work, and the pressure of the control manifold is the same
as the system.
The reducing and regulating valve controlling annular preventer can be operated either manually or
air-operated . In case of manually / air-operated system, the output pressure of this valve can be regulated by
air operation either in remote control panel or driller 's control panel. The position of air-operated pressure
regulation is determined by distribution valve in remote control panel. There are two positions on the distribution
valve: "remote control panel" and "driller's control panel".
When regulated manually, turn the hand wheel on the reducing and regulating valve, the output pressure may
be regulated to set pressure. Turning down to increase output pressure and turning up to decrease it.
The use instruction for air-operated pressure regulation is as follows:
1. When the air pressure is zero, firstly regulate manually the pressure to 10.5 MPa (1500 psi) or desired set
pressure, then lock regulating rod .
2. Turn handle of distribution valve to the position of "Driller's panel", turn the regulating knob to regulate the
control pressure of annular preventer. Clockwise turning is to decrease control pressure.
3. Turn handle of distribution valve to the position of "Remote control panel" turn the regulating knob to regulate
the control pressure of annular preventer. Clockwise turning is to decrease control pressure .
CAUTION: When air operated function fails (e.g., zero air pressure due to air cable explosion), the
control pressure for the annular preventer will be automatically reset to the initially set value (10.5
MPa or 1500 psi), in order to guarantee safety.
CAUTION: In case of air-operated pressure regulating conducted in driller's control panel, the long
air control circuit may result in the slight lagging of pressure change at the outlet of the reducing and
regulating valve. Therefore, itis advisable to pay much attention and handle it slowly.
On the remote control panel , the 3-position 4-way control valve belongs to the "O" mode category. When its
handle sits in the "middle// position, one cavity is not open to the other. When the handle is at the ''Open" position
or the "Close" position, pressure oil may enter one end of the oil cylinder, while oil in the other end may go back
to the oil tank via the 3-position 4-way control valve. Tl1e valve handle should be always kept at the "Open"
position or the "C lose'' position.
On the driller's panel, all the 4-way air operate valve may be automatically reset ("middle" position)

** Operation Manual ** Sanyi
On the upper side of the hind channel section steel of the base of the remote control panel, a welded letter
of "O'' or "C" is shown corresponding to each oil pipe, with "O' meaning "Open'' and "C" meaning "Close". The
pipes connected should not only in accordance with the instruction (blind ram , pipe ram , annular, choke, etc)
of the brand plate on the remote control panel, but also in accordance with the marked letters of "O" and "C",
so that the p.ipes may be correctly connected with the "open" or "close" function .
CAUTION: The wrong connection of pipes or wrong connection of switch directions may lead to
wrong operations. Therefore, care is needed for the identification of pipes before connection.
CAUTION: No clogging or leakage is allowed for the pipe connectors. There should be no dirt in
the pipe, or otherwise the operation of the system may be unfavorably affected.
CAUTION: When connecting air cable, take care and prevent dead bends. The pipes should be
closely connected with the connectors, so as to prevent troubles like pipe explosion and
disconnection.
CAUTION: If the seal washer is not in the correct position or the connecting bolts are not properly
tightened, the connection of the flanges at the two ends of the air cable may lead to air leak, thus
resulting in failure.

6.2 Test run
The preparatory work for the test run is carried out according to the following procedures.
a) Pre-charge or check the nitrogen pressure in each accumulator, the pressure should be 7 ± 0.7MPa (1000 ±
100 psi), and fill nitrogen when pressure not enough.
b) Fill the oil tank. Make sure the oil lever reaches its upper limit. Checking the oil of the oil tank weekly. To check
the oil after an operation cycle, if the oil is muddy, it is necessary to change the oil.
When ambient temperature is above O C, use D.T.E24 (MOBH) hydraulic oil or any proper substitute oil.
When ambient temperature is below O C, use D. T. E 13 (MOBH) hydraulic oil or any proper substitute oil.
c) Carry out lubrication according to this operational manual.
d) Opening the isolate valve of the accumulator bank. Opening the bleeder valve of the control manifold. Push
the handle of each 3-position 4-way control valve to the middle position and push the by-pass valve to the
"CLOSE" position.
e) Turn the power switch to the "MANUAL" position , the electrical oil pump will start to work. In the mean time,
check and see if the motor totates in the same direction as is indicated by the arrow on top of the chain cover.
Otherwise, you should change the phases of the power line.
The test-run procedures:
a) Test on electric-operated oil pump
Turn the power switch to the "AUTO" position. After the electric-operated oil pump rotates without any load
for 10 minutes, close the bleeder valve on the control manifold to increase the pressure. When the pressure
of the accumulator rises to 21 MP a (3000 psi) , the pump will stop automatically. (Otherwise, turn the power
switch to the "STOP BY HAND" position to stop the pump.)
Gradually open the bleeder valve to reduce the pressure of the system. When oil pressure drops to around
19 MPa (2700 psi), the electric-operated oil pump should be able to start automatically.
In the above process, check and adjust the pressure switch until the electrical oil pump stops and starts
) automatically. Check and see if there is any oil leak in the connectors on the remote control panel while the
pressure is going up.
b) Tests on the air-operated oil pump
When using the air-operated oil pump, you should close the by-pass valve of the hydro-pneumatic pressure
switch, and open the air supply valve to start the air-operated oil pump. When the pressure of the
accumulator rises to 21 MPa (3000 psi). check and see if the hydro-pneumatic pressure switch can cut off
the air supply and stop the air-operated oil pump.
Gradually open the bleeder valve on the contoi rnanifold to let the system unload slowly. When oil pressure
drops to around 17.85 MPa (2580 psi), the air-operated oil pump should be able to start automatically.
In the above process, check and adjust the hydro-pneumatic pressure switch until the air-operated oil pump
stops and starts automatically. Check and see if there is any oil leak on the remote control panel, while the
pressure is going up.
c) Test on hand-operated oil pump
When using the hand-operated oil pump, close the isolate valve of the accumulator bank on the circuit, open
the by-pass valve of the control manifold, swi ng the handle of the hand-operated pump and see if the
pressure of the control manifold goes up. When the handle of the hand-operated pump is difficult to swing,
