Precautions when using a high-pressure cleaning pump
When using a high-pressure cleaning pump, the following points should be noted: 1. Avoid starting under low voltage as much as possible. To effectively use a high-pressure cleaning pump, you need to select the correct nozzle. Some high-pressure cleaning pumps are equipped with interchangeable nozzles for various purposes. Low-pressure nozzles allow the unit to draw in detergent, while high-pressure nozzles can spray water at different angles. Choosing the right nozzle will make the cleaning process more efficient.
Daily maintenance and precautions for high-pressure washers
Pressure washer maintenance is divided into three levels. A) The first level is daily maintenance by the operator, including regular checks of the normal operating status of each component, checking the correct and intact installation of connecting pieces and fasteners, and ensuring there are no faulty parts; B) Regular inspection of valves, joints, spray guns and other parts in the equipment. This work can be carried out by the operator under the guidance of professional technicians according to the routine maintenance procedures;
What are the reasons for low cold water pressure from a high-pressure washer?
The use of cold water high-pressure cleaning machines is becoming increasingly popular in China. With the increase in working pressure of high-pressure water cleaning machines, they are now widely used in various industries, such as in rust removal. However, under some harsh operating conditions, after a period of use, a common problem with cold water high-pressure cleaning machines is low or no water pressure. Let's analyze the reasons for insufficient water pressure in high-pressure cleaning machines: 1. Severe wear and tear of the high-pressure nozzle of the cold water high-pressure cleaning machine. Excessive wear and tear of the high-pressure nozzle will affect the water pressure of the equipment. The nozzle should be checked and replaced in a timely manner. 2. Kinks, bends, or damage to the high-pressure pipe or filter device can cause water flow obstruction, resulting in insufficient water pressure. Repairs should be made promptly. 3. Air in the high-pressure cleaning machine filter. After draining the air from the filter, ensure the output of standard water pressure. 4. Leakage in the high and low pressure water seals and inlet/outlet check valves of the high-pressure cleaning machine causes the working pressure to decrease. These parts should be replaced promptly. 5. Insufficient inlet water flow to the connected equipment results in insufficient water flow and therefore insufficient output pressure. Sufficient inlet water flow should be supplied to solve the problem of reduced water pressure. 6. Aging of the overflow valve of the high-pressure cleaning machine causes a large overflow of water flow and low pressure. When aging is detected, the parts should be replaced promptly. 7. Internal failure of the high-pressure pump, such as wear and tear of wearing parts, reduced water flow; blockage of internal pipelines of the equipment, too small water flow, resulting in low pressure. Power failure. If the power voltage is insufficient, it will affect the normal operation of the high-pressure pump motor, thus reducing the output power of the high-pressure pump and insufficient water pressure. For power failures, simply restore the power. Aging of the high-pressure pump lubricating oil. Due to long-term use without replacing new lubricating oil, the high-pressure pump is affected, and in severe cases, the core component, the three-plunger valve, is damaged, resulting in insufficient water pressure. In this case, the high-pressure pump lubricating oil should be replaced regularly. Check whether the motor starts normally. If impure oil is injected into the high-pressure pump, drain the oil from the pump and then inject special high-pressure pump oil. When the water pressure of the cold water high-pressure cleaning machine is too low or there is no pressure, it will directly affect the cleaning effect and quality of the equipment. After a pressure failure occurs, troubleshooting and processing should be carried out promptly to ensure that the cleaning work is not affected. Only in this way can the service life of the high-pressure cleaning machine be extended and the equipment can be better guaranteed for long-term use.
