The Importance of Valves in High Pressure Pump Cleaning Equipment

With the increasing use of high-pressure plunger water pump cleaning machines, the demand in the market is also constantly increasing.

Especially in the field of industrial cleaning, as industrial cleaning is increasingly valued by us, this equipment is widely promoted and used.

The current high-pressure cleaning machine has become a cleaning equipment in the industrial cleaning field, and is gradually evolving towards systematization and automation.

By remotely controlling the high-pressure water generation equipment, the automation of high-pressure water jet cleaning can be ended.

Remote active controlPApressure regulating valveIt is measured by a pressure transmitter to obtain the outlet pressure of the high-pressure water generating equipment, and the measured value is converted into a digital signal, which is transmitted to the control system. The control system announces instructions as needed to open and close the electric equipment. The electric equipment is driven according to the instructions of the control systemP.A.Pressure regulating overflow valveThus ending the pressure scheduling of the high-pressure water pump cleaning equipment.

Constant pressure overflow function: In the quantitative pump energy-saving scheduling system, the quantitative pump supplies a stable flow rate.

When the system pressure increases, it will require a decrease in flow rate.

at this momentPA unloader valveOpen and allow the remaining flow to overflow back into the fuel tank, ensuringPAPressure regulating overflow valveImport pressure refers to the stable outlet pressure of the high-pressure plunger pump cleaning equipment pump (the valve port often opens with unstable pressure).

Voltage stabilizing effect:PApressure regulating valveConnected in series on the return oil line, PAoverflow valveBack pressure occurs, increasing the stability of moving parts.

System unloading function: inP.A.pressure regulating valveThe remote control port is connected in series with a small flow overflow solenoid valve. When the solenoid is powered on,PA unloader valveThe remote control port is connected to the oil tank, and the hydraulic pump is unloaded at this time.

PApressure regulating valveAt this time, it is used as an unloading valve.

Safety protection function: When the high-pressure pump cleaning machine system is working normally, the valve is closed. Simply open the overflow of the load exceeding the rules to provide overload protection, so that the system pressure will no longer increase.

The reason why high-pressure water pump cleaning equipment can work at any working pressure under the rated working pressure is that the pressure regulating valve is in operation. The pressure regulating valve is an important scheduling organization to ensure and end this work.

Due to the fact that most cleaning machines are equipped with high-pressure water generation devices that belong to constant flow volume pumps, overflow will occur at any pressure below the rated working pressure.

ButPApressure regulating valveIt is a device that can simultaneously end the pressure regulation and overflow of high-pressure water generation equipment in high-pressure cleaning machines, which is calledP.A. unloader valve.

Releasing the trigger will interrupt the flow of water to the nozzle, althoughhigh-pressure plunger pumpContinue running. If these water outlets are not released, the pressure will continue to increase. This will lead to a very dangerous situation.

pressure regulating valve

pressure regulating valveAct as a pressure regulator to guide water flow in the pressure cleaner system. When water stops flowing out of the spray gun nozzle,pressure regulating valveIt will be redirected to a safe pressure outlet. When the cleaner is in "bypass mode", the water that has not been released by the spray gun is transferred back to pressurehigh-pressure plunger pumpOn the entrance side. Then, it passed throughhigh-pressure water pumpLoop and returnpressure regulating valveOn the entrance side. Water is released again through the spray gun or redirected toHigh pressure plunger water pump. Throughhigh-pressure pumpThe process of continuing to circulate water is called 'circulation'.

• "Intercept pressure"pressure regulating valveThese valves are connected throughhigh-pressure plunger pumpEstablish pressure at the output end to sense and activate. The interception pressure valve starts the bypass mode and responds directlyHigh pressure plunger water pumpThe building pressure in the hose between the output and the spray gun. They are commonly referred to as "pressure" valves. When the cycle is interrupted, a pressure peak is generated, and the residual pressure valve releases water back into the spray gun. Operators should be prepared for the "recoil" effect on the spray gun or spray gun rod to prevent loss of control or injury.

• "Traffic driven"pressure regulating valveResponse to interruption of water flow towards the nozzle. These valves can sense a decrease in flow from the valve to the spray gun and activate the bypass circuit in response. Unlike interception pressure valves, no pressure is captured, so there will be no "blowback" when water is released again. Using traffic drivenpressure regulating valveAt this time, the operator cannot adjust the pressure by reducing the size of the nozzle orifice. The flow driven valve detects flow loss and reacts through repeated cycles.

Although cycling can prevent dangerous pressure buildup, additional safety issues may arise in bypass mode.high-pressure pumpThe moving parts in the system will generate friction and heat, which will be transferred to the bypass water flow. Circulating water can quickly heat up to dangerous temperatures because there is no cold water entering during the bypass processhigh-pressure water pump.

pressure relief valvealso known as safety valve（safety valve）It can automatically open and close according to the working pressure of the system, and is generally installed on equipment or pipelines in closed systems to protect system safety. When the pressure inside the equipment or pipeline exceeds the set pressure of the pressure relief valve, the pressure relief valve will automatically open to ensure that the medium pressure inside the equipment and pipeline is below the set pressure, protecting the equipment and pipeline and preventing accidents.

There are two main types of pressure relief valve structures: spring type and lever type. Spring type refers to the sealing between the valve disc and the valve seat relying on the force of the spring. The lever type relies on the force of the lever and heavy hammer. With the demand for large capacity, there is another type of pulse relief valve, also known as a pilot relief valve, which consists of a main relief valve and an auxiliary valve. When the pressure of the medium in the pipeline exceeds the specified pressure value, the auxiliary valve opens first, and the medium enters the main relief valve along the pipeline, and the main relief valve is opened to reduce the increased medium pressure.

Operation method: Adjustment of opening pressure of pressure relief valve

1Before the pressure relief valve leaves the factory, its opening pressure should be adjusted one by one to the set value required by the user. If the user requests the working pressure level of the spring, it should be adjusted according to the lower limit value of the pressure level before leaving the factory.

2Before installing the pressure relief valve on the protected equipment or before installation, the user must readjust it at the installation site to ensure that the set pressure value of the pressure relief valve meets the requirements.

3Within the working pressure range indicated on the nameplate, the opening pressure can be adjusted by rotating the adjusting screw to change the compression amount of the spring.

4Before rotating and adjusting the screw, the inlet pressure of the valve should be reduced to the opening pressure90%To prevent the valve disc from being driven to rotate when adjusting the screw, which may damage the sealing surface.

5To ensure accurate opening pressure values, the medium conditions during adjustment, such as medium type, temperature, etc., should be as close as possible to the actual operating conditions. When the type of medium changes, especially when the accumulated state of the medium is different (such as from liquid phase to gas phase), the opening pressure often changes. When the working temperature increases, the opening pressure generally decreases. Therefore, when adjusted at room temperature and used for high temperatures, the set pressure value at room temperature should be slightly higher than the required opening pressure value. The degree of height is related to the valve structure and material selection, and should be based on the manufacturer's instructions.

6Conventional relief valves are used to fix additional back pressure. When the opening pressure is adjusted after inspection (the back pressure is atmospheric pressure at this time), the setting value should be the required opening pressure minus the additional back pressure.

feature1Accurate and stable safety pressure, once overpressure occurs, the pressure relief valve can fully open and release pressure in a timely manner.

2The closing speed can be adjusted to eliminate pressure fluctuations.

3The diaphragm transmission mechanism minimizes the phenomenon of operation lag.

4It can be installed in any position without changing the pressure setting or removing it from the pipeline for maintenance and inspection.

PAThe pressure regulating valve is a small and important component that ensures the effective and efficient operation of reciprocating high-pressure pumps.

What isPAPressure regulating valve?

high-pressure pumpPAThe pressure regulating valve is a very small component, usually with a size of 4to5Between inches. The valve releases the trapped water from the high-pressure pump box, thereby restarting the motor. ifPAThe pressure regulating valve cannot release water, and the accumulated pressure may prevent the motor from starting.

The type of valve for high-pressure water pumps depends on the brand and size of the machine. Some are operated through the toggle switch on the side of the device pressure switch. Others have installed an integral valve below the pressure switch.

PAWhat is the purpose of a pressure regulating valve?

During the operation of a typical reciprocating high-pressure plunger pump, the machine's electric motor drives the water tank to be filled with water. The device includes a pressure switch that responds to water accumulation by turning off the power to the motor. The high-pressure pump connected to the motor shaft also stops.

When the motor attempts to restart, the trapped water will generate a load that limits its opening ability. By draining water,PAThe pressure regulating valve effectively reduces the load on the piston, thereby facilitating the process of re powering.

PAWhere is the pressure regulating valve located?

PAThe pressure regulating valve is located at the top or inside of the pressure switch of the small reciprocating high-pressure plunger pump. When the switch closes the high-pressure pump, it will activate the valve. A small pipe or a pipe extends from a check valve (a device that prevents the entire tank from emptying) toPAPressure regulating valve.

Larger high-pressure piston pumps typically include larger onesPAPressure regulating valve. It is controlled by the water pressure released by a smaller pilot valve. In this arrangement, the valve is usually located next to the high-pressure pump.

PAHow does a pressure regulating valve work?

When the water pressure in the high-pressure pump tank reaches a level where it cannot deliver more water, the valve switch will automatically interrupt the power supply to the motor. After the power is turned off,PAThe pressure regulating valve opens and discharges the accumulated water.

When the pressure in the water tank drops back to the predetermined setting on the pressure switch, it will cause the switch to trip again. This action causesPALoosen the pin of the pressure regulating valve to prevent compressed water from escaping into the atmosphere.

How to replacePApressure regulating valve

PAPressure regulating valve failure is one of the most common problems that cause high-pressure pumps to malfunction. When water cannot escape from the storage tank, the accumulated pressure often hinders the ability of the equipment to restart.

whenPAWhen the pressure regulating valve malfunctions, it becomes unable to open or close. The opened valve releases a continuous flow of leaking water. A closed valve can cause significant pressure buildup, thereby limiting the internal components of the pump. When internal components cannot move, this will prevent the engine shaft from opening.

You should replace the faulty unloading valve as soon as possible to avoid them affecting other critical high-pressure pump components. Learn about how to replace belowPAMore information about pressure regulating valves.
