Approved Ul Testing Lab Certification Standards Pump Machinery Third-party authentication service

Provide all kinds of industrial machinery products testing certification

It mainly includes agricultural machinery, mining equipment, metallurgical equipment, power equipment, chemical equipment and working mother machinery and other manufacturing industries. Machinery manufacturing industry is the heart of the industry, it industry, agriculture, transportation, national defense, etc. To provide technical equipment, is the material of the national economy and defense modernization technology base, therefore, machine-building industry developed or not and machine and equipment level of self-sufficiency is to measure a country's economic development level and the real symbol of the levels of science and technology. There are many categories of machine manufacturing, which has become the largest industrial system with dozens of independent production departments. Because of the complex structure of machine products, parts and components, strong technology, so the implementation of production specialization, standardization, automation for the development of machine manufacturing industry is of great significance.

Product range:

Agricultural machinery, mining equipment, metallurgical equipment, power equipment, chemical equipment, digging machinery, shovel transport machinery, construction lifting machinery, motor industrial vehicles, compaction machinery, road machinery, piling machinery, concrete machinery, steel processing machinery, decoration machinery, drilling machinery, other special construction machinery.

A pump is a machine that delivers or pressurizes a fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, so that the liquid energy increases. Pump is mainly used to transport water, oil, acid alkali liquid, emulsion, suspension emulsion and liquid metal and other liquids, can also transport liquid, gas mixture and liquid containing suspended solids. Pumps can usually be divided into positive displacement pumps, power pumps and other types of pumps according to the working principle of three types. In addition to the working principle of classification, can also be classified and named according to other methods. For example, according to the driving method can be divided into electric pump and hydraulic pump; According to the structure can be divided into single stage pump and multistage pump; According to the use can be divided into boiler feed pump and metering pump; According to the nature of the conveying liquid can be divided into water pump, oil pump and mud pump. According to the shaft structure, can be divided into linear pump, and traditional pump. The pump can only transport with fluid as the medium of logistics, can not transport solid.

1. Testing standard (part)

Pump CE certified range

The Mechanical CE Certified MD Directive applies to all new pumps and pump installations.
The areas of application given in Article 1 (3) of Chapter 1 of the Mechanical CE Certification Directive are not limited in scope, for example: Pumps and pump, the only power source used for medical purposes of pumps and pump directly, used in direct contact with patients, pumps and pump, specially designed for nuclear intentions or put into use, in the event of failure, may result in radioactive substances, emissions of pumps and pump, used for ships or mobile offshore units, which are designed for military or police pumps and pump assembly.
In addition, the CE certified Machinery Directive applies to safety components placed on the market separately. The safety components in accordance with Appendix IV B of the Directive include:
Electronic sensitive devices are specifically designed to detect people to ensure their safety, logic units to ensure the safety of two-handed controls,
Automatic active screen saver 9,10 and 11 of the printing press (annex IV A),
Rollover Protection Structure (ROPS),
Falling Object Protection Structures (FOPS).
Currently, pump and pump unit safety components are not applicable. In addition, the EC directive machinery does not apply to individual parts and spare parts and repairs that do not modify mechanical functions.
In the case of pumps and pump installations, the risk is primarily electrical, and according to Section 1 (5) of Chapter 1, low voltages are required, and the corresponding electrical risk is already included in the mechanical instructions

The standards applicable to mechanical products are generally divided into the following categories:

Class A standards (Basic safety standards)
It is mainly about basic concepts, design principles and general requirements applicable to all machinery.
Class B standards (safety standards)

are mainly used to deal with a safety situation or a related safety facilities, which can be widely used in a variety of machinery;
Class B1 standards for specific safety conditions (e.g., safe distance, surface temperature, noise)

The B2 standard is for relevant safety facilities (e.g., two-hand controls, interlocking devices, pressure sensing devices, shields).
Class C standards (Machine safety standards)

are mainly used for the detailed safety requirements of a particular type or class of machines.
Class C standard has the highest authority among these three standards, that is, if the same machine adopts class A, B and C standards at the same time, the requirements of class C standard have the highest priority. Class C standards are usually also called product standards. For example, EN201- Safety Requirements for Injection Molding Machines, which provides detailed and specific requirements for all possible risks of injection molding machines, basically including or referring to the requirements of class A and class B standards related to this type of products.

The most commonly used A, B and C standards for mechanical products are:
Class A standard: ENISO12100: Basic design Principles for Mechanical safety - Risk assessment and risk mitigation; .
Class B standard: ENISO13857: Safety of machinery - safe distance to prevent extension of upper and lower limbs and hazardous areas;
ENISO4413: Hydraulic systems - General requirements and safety specifications for hydraulic systems and hydraulic components;
ENISO4414: Pneumatic systems - General requirements and safety specifications for hydraulic systems and hydraulic components
EN1088: Safety of machinery - Interlocking devices mounted on shields - General principles of design and methods of selection;
EN953: Safety of machinery - General requirements for the design and construction of stationary and mobile shields;
En60204-1: Safety of machinery - Mechanical electrical equipment - Part 1: General requirements.

Class C standard :EN201: Plastics and rubber machinery - Safety requirements for injection molding machines
En415-1: Safety of packaging machinery - Part 1: Terminology and classification of packaging machinery and related equipment;
En415-5: Safety of packaging machinery - Part 5: balers;
En474-1: Earth-moving machinery - Basic safety requirements
EN692: Machine tools - Safety of mechanical presses;
EN693: Machine tools - Safety of hydraulic presses;
EN860: Woodworking machinery - Single plane;
EN869: Safety of machinery - Metal die casting machines;
EN1493: Automotive lifter;
EN12417: Machine tools - Safety requirements for machining centres;
EN12717: Safety of machine tools - Drilling press;
