Product Description

Explosion Proof High Pressure Machine

We, Henan Boy Machinery Co.,Ltd, are a leading manufacturer in hydro jetting machine.
We cooperate with German and US teams and have rich experience in the machine in China with much lower price and shorter delivery time. Until now our products are widely used in below industrial field:

Surface prep & cleaning
Stone Cutting
Pipeline cleaning
Cooling tower cleaning
Fuel tank cleaning
Water jetting cutting

With the iterative update of technology and the increasingly strict operation requirements, traditional cleaning equipment is difficult to meet the current technical requirements. The defects of insufficient supply pressure and low flow rate are increasingly obvious, and the innovation of ultra-high pressure explosion-proof cleaning machine can solve the current technical defects, and the emergence of explosion-proof technology can effectively avoid the safety hazards caused by gas, dust and other explosive substances. Today, our equipment technology has become more mature and widely used in petrochemical, medical, mining and other fields.

Safety Standards
Our products are based on the JCB 444 naturally aspirated diesel engine and can be fitted with thenecessary safety equipment to meet the following safety standards:
Lloyds Open Deck Zone 2 Areas
OCMA MEC 1
BS 5908 Zones1&2
BP 200
Shell ISO 27
EEMUA No 107(1992)
ATEX (94/9/EEC)
Working principle
The principle of operation is to limit all surfaces and exhaust gas temperatures to below 200°Cand offer automatic shutdown of the engine should high coolant water temperature, high exhausttemperature, low oil pressure or engine overspeed occur.  
                                                                                     
EX-Proof Components


Classification of explosion-proof area

The EU ATEX certification, also known as the EU CE certification for explosion-proof products, is for equipment used in potentially explosive environments and divides products into two broad categories:
1. Group 1 equipment mainly refers to coal mine underground equipment, including coal mine ground equipment threatened by gas and (or) powder small explosions: according to the different safety protection levels, Group 1 equipment can be divided into M1 category equipment and M2 category equipment.
2. Group 2 equipment refers to non-coal mine equipment, Group 2 equipment can be divided into 1, 2, 3 categories.
a. Class 1 explosion-proof products with dry explosive gas, dust, steam or mixture for a long time or frequent occurrence of places, with a high level of protection, when there is a fault, there is at least one independent protection to ensure the level of equipment safety protection, when there are two independent failures, the equipment can still ensure its level of safety protection;
b. Class 2 explosion-proof products are used in places where explosive gases, dust, steam or mixtures may appear, with a high level of protection, and the equipment can still guarantee its level of safety protection after disturbance or expected failure;
c. Class 3 explosion-proof products are used in places where explosive gases, dust, steam or mixtures do not appear under normal circumstances or occasionally appear for a short time, and can ensure their safety protection level during normal operation.


Advantage
Compared with ordinary pumps, explosion-proof pumps have the following characteristics:
anti-explosion
Corrosion resistance
Good sealing
Reliable performance
Long service life
Stable operation
Application Sites
Ship repair, automotive painting, coal chemical industry, marine oil, electric power, aluminum, paper making, mining, cleaning companies and other fields, surface paint rust removal and rapid removal of scale from the inner wall of the pipe.
