Air compressor common faults and the solution to the water heater
Author: www.dg-zhihe.com      Release Date:2012/11/5      View Count:5627
 
 
Air compressor common faults and the solution to the water heater
 
Solution: ambition and air compressor manufacturer at a water heater, the manufacturer has various parameters qualification adjustment, circulation (straight hot) water pump water temperature to 80 ℃ set off the job, the ChouShuiBeng set 60 ℃ work, ChouShuiBeng work at 11 minutes, air compressor fan set 90 ℃ start, 80 ℃ to stop working.
 
A water heater, air compressor part:
 
1, temperature display abnormal
 
(1) into the air compressor water heater PLC control panel calibration temperature;
(2) to examine whether the temperature probe corrosion, signal induction is not strong, twist the temperature control with sand paper burnish a probe or replace probe;
(3) inform the supplier detection thermostat;
 
 
2, the host machine will not work, circulation (straight hot) water pumps don't turn
 
(1) check the water pump operation is correct, the reverse: change the power cord, such as not turn: check whether the power cord are connected correctly, such as water pump is burnt out to change;
(2) to check whether the power access normal, running lights is light;
 
3, circulating water tank hot water temperature couldn't get on
 
(1) check whether the circulating water pump;
(2) check air compressor is running and loading time, such as air compressor is not running, or operation not loading, there will not be thermal energy utilization, is a normal;
(3) according to the water quality and pneumatic water heater use time and air compressor water heater production in whether water, to judge whether the air compressor water heater to scale maintenance;
 
Second, circulation water tower part:
 
1, circulating water tower no filling water
 
(1) check whether water quality filters jams, cleaning filter or to change;
(2) check whether t. water cut of water, or tap water pressure is too low, can open water filter drain valve observations;
(3) check (high, medium) water level wire break the skin and cistern whether by iron, the tape wrapped or replace the electric wire.
(4) check circulation water tank probe whether corrosion, signal induction is not strong, open wiring head with sand paper burnish or replace probe;
 
2, circulation water tower no circulating water
 
(1) check whether time send water pump, to give water pump emptying, open the circulation line installed emptying ball valve;
(2) check whether the circulating water pump in work, such as not work the machine according to the internal control of circulating pumps ac contactor touch head and see whether water pump operation, such as not running water pump that burn out, replace the water pump;
 
3, circulating water tower excessive water
 
(1) check whether there is water electromagnetic valve seal grooves in the dross, the electromagnetic valve closed lax;
(2) check circulation water tank probe whether corrosion, signal induction is not strong, open wiring head with sand paper burnish or replace probe;
(3) if the above normal check, then inform the supplier control panel and water level detection host controller;
 
Three, heat preservation water tower part:
 
1, ChouShuiBeng to set temperature does not work
 
(1) check whether water pump burn out;
(2) to start down water pump temperature, observe whether to pump start-up;
(3) ChouShuiBeng start set temperature ± 2 ℃ are of normal
(4) the factory set ChouShuiBeng work interval for 12 minutes
 
2 water tower, heat preservation with water
 
(1) check whether there is water electromagnetic valve seal grooves in the dross, the electromagnetic valve closed lax;
(2) check whether the insulation water tank probe corrosion, signal induction is not strong, open wiring head with sand paper burnish or replace probe;
(3) if the above normal check, then inform the supplier control panel and water level detection host controller;
 
3, heat preservation water tower no hot water
 
(1) to start down water pump temperature, observe whether to pump start-up;
(2) to examine send water pump start-up temperature, check whether there is water circulation set temperature of hot water, can observe machine temperature display, or hand induction water temperature.
(3) to examine whether time send water pump, to give water pump emptying;
(4) check to send water pump is running, press machine to the internal control pump ac contactor touch head and see whether water pump operation, such as not running water pump that burn out, replace the water pump;
(5) check whether the insulation water tank probe corrosion, signal induction is not strong, open wiring head with sand paper burnish or replace probe;
(6) check (high, medium) water level wire break the skin and cistern whether by iron, the tape wrapped or replace wire;
(7) using a multimeter to test the thermostat and temperature control signal lines;
(8) check whether conduit leakage, send blocked;
