WREN Hydraulic

Safety Guide

The hydraulic torque wrench pump's safe usage requires correct operation and

regular inspect. And the user is requested to follow always and carefully .

▲precaution to avoid direct loss in economic or property.

▲warning to avoid personal injury.

Please follow herein before!

When using, if something abnormal happens, please shut off the power

immediately, and then consult WREN or WREN`s agent.

1.When using, do not permit any person stand at the oil output in order to avoid personal injury and

equipment damage. Please put the pump far away from the fire.

2.Make sure that the hose and quick coupler be connected before building up the pressure in order

to avoid hydraulic fluid spurting out to cause personal injury.

3.The maximum operating pressure of this pump is 70Mpa(10,000Psi),WREN has set up the

pressure to 70Mpa before selling this pump. Please do not adjust to a pressure higher than the

maximum pressure which WREN has not set.

4.If this pump is used for operating other equipments, make sure the maximum operating pressure

of the equipments will be less than 70Mpa. Please adjust the pressure to which the equipment need,

or else the equipment would be damaged.

5.Make sure the power of the pump is shut off before repairing it.

6.Please shut off the switch before starting power; if the switch is on, the pressure may increase.

7.Make sure the equipment be connected with ground to avoid electric shock.

8.Please do not change any part of the pump; if it must be changed, please inform WREN or Wren's

agent for help. Without allowance of WREN or its agent, any refit of it will be out of our warranty

range.

9.Please do not fill the pump reservoir with too much oil, otherwise, the pressure of the reservoir will

increase and the oil will spill over, so the reservoir will be broken and the environment will be

polluted.

10.Automatic operation button is pressed, the automatic cycle start button switch bounce, automatic

program stop. Under a state of emergency, you must first cut off the power supply of a motor.

11.Make sure the quick coupler is tightened; if the quick coupler is not tightened enough, the

equipment will not work normally; if it is a synchronic system, the problem may cause one or several

pieces of equipment out of order and the quick coupler may be broken and it may cause personal

injury or equipment damage.

12.Please stand away from the position where the hydraulic oil may be spurt out; hydraulic oil may

penetrate your hand and hurt you.

13.If the hydraulic oil splashed in your eyes, please immediately wash your eyes about 15 minutes

with clean water, then you must go to hospital for help right now.

14.Electrical box with flashing lights. If the bright lights, the circuit fault. Usually the indicator does

not work. If there is light to timely repair

15.The wrench and power pump are connected by a 700 BAR operating pressure, twin-line hose

assembly. Each end of the hose will have one male and one female connector to assure proper

interconnection between pump and wrench.

16.Please do not touch the pressurized hose; if the hydraulic oil splashed out, it will cause serious

injury.

1.Only WREN hydraudic special oil available.

2.Do not use pressure regulate valve as relief valve.

3.The used hydraulic oil should be put away according to the antipollution ordinance.

1.This pump is used for hydraulic torque wrench and fitted in integrated way, it is an independent

hydraulic unit that mainly consists of pump, control valve, oil reservoir, motor, meter, control-line

fitting, it has the peculiarity of small volume, light weight, simple composition, convenient operation,

high working pressure. The pump can supply oil with one high and one low oil outlet at the same

time, which could make a large quantity of oil outputting. On high pressure, the low pressure pump

will automatically let oil return through the release flow valve, which can reduce power consumption,

and the pressure of the outlet can be arbitrarily adjusted from 70 to 700 bar.

2.Hydraulic oil for this pump:46# anti-wear hydraulic oil.

3.Environmental temperature for using this pump:-10~60

4.Please use Wren's high pressure hose, high pressure coupler, and so on. The maximum operation

pressure of high pressure hose for this pump is 100Mpa; please choose suitable system for it.

5.If you need to use attached hydraulic product for pump, please contact WREN's engineers.

6.Please do not use this pump around the fire.

7.Please do not adjust the pressure valve arbitrarily to avoid personal injury or equipment damage

due to high pressure.

8.Please confirm that the voltage for this pump is the same as the voltage of using on the spot.

9.You'd better use the pump indoors, please protect the pump from rain if it is used outdoors.

1.Oil reservoir: to store hydraulic oil, make sure there is enough oil to keep the pump working

normally.

2.Bolt: to connect motor and oil reservoir.

3.Air Motor: provide power, 4~8MPa

Oily water separator

: separator the oill and woter from the air.

5.The air input valve: to let the low preasure air into system.

6.Radiator: to exclude the heat, ensure the operating time and life of the pump.

HYDRAULIC PRINCIPLE

WARNING FOR USING HIGH PRESSURE HOSE

1.Please use Wren's JH series high pressure hoses.

2.The minimum bending radius: R>120mm. Too small bending radius will destroy the high pressure hoses.

3.The maximum operating pressure is 70 Mpa, and it is forbidden to overpass the pressure.

4.Do not tighten hoses excessively. Over tightening can cause to premature thread failure or high pressure

fittings to split at a pressure lower than their rated capacities.

5.Should any hydraulic hose rupture, burst, or need to be disconnected, immediately shut off the pump. Never

attempt to grasp a leaking pressurized hose with your hands. The force of escaping hydraulic fluid could cause

serious injury.

6.Do not use the hose to remove attached equipment. Stress can damage the hose, causing personal injury.

7.Do not subject the hose to potential hazard such as fire, sharp surfaces, extreme heat or cold or heavy

impact. Do not kink, twist, or bend the hose so tightly that oil flowing in the hose is blocked or reduced.

Periodically inspect the hose for wearing, because any of these conditions can damage the hose.

8.WREN JH series 100Mpa high pressure hose's operating pressure is 100Mpa,. Overpass this pressure is

forbidden.

2. 1 运时注意轻拿轻放。搬

2. 2 运时应将产品立式向上，如下图装所示。

2. 3 产品搬运一般采用手提式或小车搬运移动、吊装移动，如下图所示。

1.先将油箱充满标准干净的液压油，液压油应采用国标32#（冬季）或46#（夏季），当加注的液压油

达到液压泵油箱上的油窗所示警戒线时，即刻停止加注，同时旋紧油箱上方的加油孔盖。

2.检查和接好进油和回油橡胶高压软管。注意查看油管与泵体之间、油管和工作机械之间的接头是否

完好、紧合。

3.检查并接好主电源线，检查电源线路和各电器元件，是否完好。如：压力表、电机、自动化电器控

制箱等，防止在运输过程当中有损坏。

4.启动电源开关，按下电机开关，让整个泵站在非工作的情况下自动运行2-3分钟。此时，泵站内应

正在将内部的空气排出，同时请注意观看电机是否正常运转、整个泵体有无异常声响或震动。

5.经过以上的准备工作，如没有发现有任何异常现象即说明泵站的基本工作是正常的。此时将手柄手

手动操作按钮按下，反复几次排清高压软管中空气。

6.在按下手动按钮时候要注意观察压力表指针是否向上抬升，否则说明泵站的压力工作情况不正常，

请捡查排查故障。

操作方法（压力调整）

T型旋钮

顺时针转动调高压力

锁止

7.按下手动按钮，调节调压阀至设定压力。

系统压力达不到额定压力

溢流阀调整得过低压力表检测，溢流阀调至系统额值

水油混合换油

贮油箱内油量不足加注油

系统反复空运转数次，排尽空气吸入空气

节流阀、手动单向阀未关紧锁紧阀

节流阀、手动单向阀未调整到位调整至正确位置
