First, the long-term operation time under high temperature conditions: since June, the day is even and you have exceeded 30 degrees; but since June 2, after the overhaul, the production resumed until July 1; the inverter arrived since it was put into operation. The longest continuous operation time is 584 hours; the average daily output exceeds 1800 tons.
Second, the stability is good; the conditioning function is excellent: in the operation cycle; the inverter can get used to various changes in the production process; the various types of salt production are satisfied; the stepless speed regulation can be applied to the motor speed according to the needs. .
Third, the power saving effect is significant: according to the observation; the inverter at the 48HZ is more than 9.56KWH when it is 50HZ. h, at 50HZ, saves 10. 2KWH when compared to the inverter. h.
Fourth, the problem worthy of attention:
1. The operating temperature of the inverter should comply with the safe operating temperature of the electronic components; the current temperature of the power distribution room is high; it is recommended to install two 5P air conditioners in the power distribution room; perform useful cooling and dehumidification on the power distribution room; The service life of the device.
2. The best operation method of the inverter should be the dynamic adjustment of the reaction volume; however, we have not yet reached the operation method; we should increase the exploration of the dynamic conditioning operation method of the inverter response; now we are selecting hot and cold air. The machine inverter starts the exploration of the operation method; it is expected to receive strong support from the Skills Quality Department.

Galvanized Roller Shutter Door
Using advanced hot-dip galvanized material , precision roll forming production process, polyurethane foam that free of hydrofluorocarbon inside door, light weight, high strength, appearance nice. The doors have advantages of tamper anti-theft , noise isolation thermal insulation and corrosion resistance;the doors are widely used in shops, garages, houses, supermarkets, warehouses and industrial plants,etc.
Depending on the characteristics of the buildings,we can choose interior, exterior and intermediate three different installation ways, doors stay in the upper part of door after rolling up , this could save garage space, and also could keep the garage clean and beautiful by prevent the mud, rain and snow ,etc going into the garage.
