Model: NL-KFZJ-2
The problem
After the housing goes on, the finished unit faces the closing check before shipment: outlet volume, outlet temperature, power and steam-pipe water content - four data points that take a dozen minutes per machine by hand and leave no record. A housed machine hides leaks far better than a bare sub-assembly, and by the time the customer finds one, after-sales cost has multiplied.
Capability
The programmable flow table runs the sequence automatically: intelligent water filling to the set flow, the machine powered into its modes, outlet volume and outlet temperature sampled at the extraction head, a power meter above 3000W reading to two decimals, and steam-pipe water content monitored throughout - all four recorded and written to MES, with any excursion protecting the station and lighting the lamp. The built-in 0-25bar gauge reads extraction pressure directly. Two stations run independently on a 600x1200mm drain-fitted bench of splash-proof fire-retardant board; per-station and master leakage switches give two levels of protection; 5-pin sockets include one UK 3-pin; the independent variable supply 110-240V covers export models. Two units supplied and wired side by side form a four-station line, at roughly 3-5 minutes per machine.
Applicable standards
The assessment follows the leakage current and structural safety clauses of GB 4706.1 General requirements for household and similar electrical appliances, with whole-machine safety under GB/T 4706.19-2024; the four judgement thresholds and the test flow follow the customer technical agreement and the machine specification.
