Commercial hot and cold water high-pressure cleaners are also unavoidable in the long-term operation of some of the work failure, especially in different workplaces, different operators, different environments, the device may appear different failures, below Mainly introduce two examples.
First, the reasons for the low pressure of commercial cold water high-pressure cleaners and treatment methods There are two reasons for the formation of low water pressure, one is external, one is internal.
1. The external causes of external causes include mostly unclean water supply, insufficient water supply, and blocked water supply filters. This is a common failure that is not noticed by ordinary users. The solution is to increase the pressure of the water source and clean the water supply filter.
2. There may be many kinds of internal cause internal conditions, such as damage to the water seal, damage to the check valve, or improper switching due to foreign matter being lifted, pressure regulating valve not regulating properly, wear of the plunger, and plunger chamber, swash plate, spring Damage can cause stress. The solution is to replace the damaged parts.
Second, commercial hot water high pressure washer boiler can not be normal ignition causes and treatment methods
1. Reasons why commercial hot-water high-pressure cleaner boilers cannot be properly ignited General commercial hot-water high-pressure cleaners use high-voltage electrode discharge ignition, and then control the fuel supply and control boiler combustion through solenoid valves. There are usually several reasons why they cannot be properly lit: Temperature control damage, pressure, flow, oil supply, etc. Sensors do not transmit working signals normally, and diesel pump is damaged, injectors are blocked or damaged, oil pump outlet valve is blocked or the position is incorrect , ignition coke, misplaced or damaged.
2, the processing method First look at the correct position of the ignition fork, whether there are high voltage arc at the top of the two electrodes, at the same time look at whether the fuel injector injection, so you can determine whether the ignition or not.
(1) The reason for the non-ignition and non-ignition may be due to the coke or the wrong position of the ignition fork, which can be solved by a little processing, and the ignition fork can be replaced when necessary.
(2) No oil supply If it is not for oil supply, check whether the oil pump is working normally. Open the return oil pipe and check if there is normal return of oil in the return pipe. If there is oil return, it can be judged as the fuel supply solenoid valve. no job. The solution is to use a multimeter to measure if the solenoid valve is damaged (usually about 24Ω). If the solenoid valve is damaged, replace the solenoid valve. If it is not damaged, you need to check whether it receives the voltage signal; if there is no voltage signal, you can determine it as Circuit failure, then from the temperature control to the pressure switch, flow valve, oil level switch one by one check, where nowhere to determine the location of the fault, repair can be resolved. If there is no normal oil return, it can be determined that the oil pump is damaged, and it can be replaced or repaired.

Stainless steel Bathroom Accessories
Stainless steel bathroom accessories are made of stainless steel, sus304 stainless steel with brushed nickel finished, others use 201 stainless steel with chrome plated. Compared to Space aluminum bathroom accessories, stainless steel is hard and looks better. Stainless steel bathroom accessories are the economical and practical choice for most people in term of cost and material.
