Dry vacuum pump safety instructions

The safety instructions section describes

Instructions and warnings to be understood and followed during the operation and maintenance of dry vacuum pumps. Pump operation and maintenance personnel must master the safety knowledge, improve their own protection and equipment protection ability.

1, the preface

1) do not operate the equipment before reading the instruction manual;

2) be sure to have enough safety warnings and use necessary safety equipment to avoid danger during equipment installation and operation.

2, pay attention to

Please do not remove, cover or stain the label above.

If the above warning is not correctly complied with, it may cause personal injury to the operator.

3, safety

1). Personal training and job certification

The responsibility of the person operating the equipment must be clearly defined. If you do not have the necessary professional knowledge, you must be trained by the seller to ensure the safe operation of the machine.

2). Risk of not complying with safety instructions

Failure to comply with safety instructions will lead to personal, environmental and system risks and losses. For example, you may face the following risks:

Leading to major system failures certain maintenance and repair procedures that cause damage put operators at risk for electrical, mechanical, and chemical hazards by releasing hazardous materials into the environment

3) operation safety guide

When inhaling spontaneous combustion gas, especially oxygen, inert gas should be introduced.

These are considered possible hazards when the feed medium is chemically unstable gas or vapor, and additional safety measures are required to prevent the formation of polymerized or hydrogen peroxide.

When flammable, explosive, toxic and high-temperature gas or water vapor is used as the feed medium, make sure there is no danger to the environment or people.

The parameters of flow rate, temperature and pressure in the vacuum system are set for safe operation. When changing the parameters, please consult the vacuum pump manufacturer to avoid removing parts during operation, such as the coupling of the coolant vacuum pump.

The leaking dangerous media must be dealt with immediately to avoid harming people and the environment. The corresponding laws and regulations must be observed.

The risk caused by electrical has been excluded (details are as follows: local enterprise certification, VDE certification).

4). Safety guide for maintenance, inspection and installation

When the vacuum pump is switched on and off, strictly install the items in the code of practice.
When conveying dangerous medium in the vacuum pump system, it should be discharged in time.

5). All safety protection devices must be reinstalled, and after the completion of installation, an operation debugging must be carried out.

When re-debugging the device, follow the instructions in the operator’s manual.

If it is necessary to disassemble the vacuum pump, the vacuum pump needs to stop first. When it has to stop completely, the vacuum pump can be disassembled after disconnecting with the electrical unit.

6). Change and use non-original spare parts without authorization without consulting the vacuum pump manufacturer, the equipment cannot be modified and new modules added. The use of the original plant spare parts or through the factory authorized by the factory on the safety of more guaranteed, I plant for the use of other manufacturers spare parts caused by the consequences of any legal responsibility.

4. Preparation for operation

(1) empty the vacuum pump and the dust in the pipeline;

(2) check whether all suction and discharge exits are connected well;

(3) clean the pipe thoroughly and do not allow welding slag to stay in the pipe;

1. operating procedures

Operate according to the conditions (such as pressure, temperature, voltage, etc.) allowed by the supplied data sheet.

The function of the safety equipment must be ensured

(1) check the start command.

System from a self – diagnostic system (motor self – diagnostic system) this process takes several minutes.

(2) in operation mode (vacuum mode), the “operation” command is useful.

(3) the stop command can stop the vacuum pump at any time. At the same time, the vacuum pump enters the stop controlled state. The vacuum pump stopped slowly to prevent trouble.

(4) the vacuum pump can be started at any time.

2. problems of attention

(1) the supply of purified gas shall not be interrupted unless the system is serviced.

(2) avoid excessive stress concentration on the pipeline (due to thermal expansion and installation problems)

(3) when the discharge pipe is closed, the system cannot be started

(4) the accumulated condensate shall be eliminated as required

(5) condensation is allowed at continuously low flow rates, but the influence of condensation factors must be prevented.

(6) the system cannot be operated when the suction pressure is higher than the discharge pressure.
