jic hydraulic fittings Gas cooker variety on the market today

Buy gas stoves relevant considerations
Gas cooker variety on the market today , the authenticity of the pros and cons exist, how to choose economic security, reliable and practical gas cooker it? Consumers should have some knowledge of the gas stove .
First, the first choice jic hydraulic fittings of the type of gas stove should be adapted to local gas source. Roughly divided into liquefied petroleum gas (Y), artificial gas (R), natural gas (T) of the three categories, the calorific value of these three gases , the gas pressure is different, if the gas stove type does not match , the risk will occur , it applies to a different gas sources stove must not be mixed. Stove before the election , one to distinguish between gas species.
Second, packaging, labeling should be complete. Packaging should be marked with name and address, type , etc. , each stove should have a certificate, instruction manual. Stove side panels should nameplate nameplate on the make, model , applicable to gas and pressure, heat flow and production date.
Third, proper heat flow . Designed to heat domestic gas magnitude greater the heating capacity of the stronger , raging fire that is usually said . Consumers are willing to elect stove over high heat , in fact , the size of the heat flow and cooking stove should adapt , as the blind pursuit of large heat flow , will greatly reduce the stove thermal efficiency, increased waste gas emissions.

3 , the electrical control system, the control circuit applies PLC circuit , it is easy to repair circuits , easy maintenance and replacement simple.
4 , mold and die holder withhold cumulative error -free machining process to ensure that the withholding of withholding product evenly spaced lines , no size head phenomenon .
5 , in order to withhold Bsp fitting permanent mechanical precision and life on the locking mechanism assembly , not only chose the high-quality steel materials, and the use of a unique heat treatment process. So crimping machine long life : the selection, heat treatment, machining process and the reasonableness of the structure are inseparable !
6, for double-column crimping machine , C -type crimping machine easy to set up because they do not die positioning, numerical methods must be used to control withhold size.
7 , withhold standard
Theoretical requirements : not from the head , does not destroy the rubber hose
In order not to take off the head - withhold efforts should be large , in order not to destroy the glue - withhold efforts to be small. To resolve this conflict without crimping machine to choose the first taper ( 0 taper ) pressure pipe machine so that both ends of the front and rear hydraulic metal joints consistent data to avoid errors. ( Note: If the front metal joints compressed intensity is too large , will be crushed if the metal connector joints backend compression intensity is too large , the rubber hose will fracture , causing the hose leakage , etc. ) .
