Equipment composition of polyurethane elastomer pouring machine?

The emergence and development of any industry is inseparable from the progress of science and technology, which is also the promotion of the industry caused by the continuous expansion of market demand, and promotes the continuous upgrading of products by relevant personnel. then in the processing industry, this requirement is even more, suchPolyurethane elastomer casting machineThe processing is also from the traditional process to more advanced technology processing, then itsEquipment compositionWhat are they? What should we pay attention to when using it at the same time?

Both the low press and the high pressure press of the polyurethane elastomer pouring machine are used for the double foot separation of polyurethane. The low press relies on the high-speed rotation and mixing of the motor mixing head. High pressure mixing in the mixing chamber, no need to clean after use. Polyurethane elastomer casting machineofDope systemThere are two, and they areA,BIndependent, the raw liquid is transferred from the feed tank through the discharge valve, filter, metering pump to the pouring head and then back to the feed tank through the return valve to maintain the required temperature during heating operation. And the entire system is required to be closed to prevent leakage from breaking the vacuum or deteriorating the original solution.

AndPolyurethane elastomer casting machineofHeat conduction oil system,The same is alsoA,BIndependence. The heat transfer oil in the oil tank is transported to the material tank by the circulating pump, and the discharge valve, filter and metering pump are heated by the casing and block at the lower part of the material tank, and then shallowly injected through the casing. head, and then back to the tank through the casing. Vacuum system: material tank through true5Buffer tank to true2The pump, the real on the tank2Pressure gauge can display vacuum degree. The pipeline is required to be as short as possible, with fewer joints and valves to prevent air leakage. Hose connection in the middle. Compressed air system: compressed air (6~8kg/cm2) (User-provided) After passing through the water separator and pressure regulating valve, it is divided into three ways: after passing through the oil injector, the oily compressed air immediately enters the pouring head to switch the cylinder to operate "return"-"pouring" switch and cleaning cylinder control cleaning switch. After pouring to the pouring head for air flushing. Go to the cleaning fluid tank that delivers the cleaning fluid.

The polyurethane elastomer casting machine is automatically controlled by a computer program controller through a solenoid valve. Cleaning fluid system: the cleaning fluid tank is equipped with level gauge, pressure gauge and vent valve. After the cleaning fluid passes through the filter, one-way valve and solenoid valve to the pouring head cleaning switch, it isA,BThe discharge port enters the mixing chamber synchronously and is automatically controlled by the computer program controller for liquid addition washing or air flushing. Frequently used foaming machine can ensure that there is no mechanical failure; intermittent use of foaming machine during the shutdown every1-2Do it once in a day.30Minutes of high and low pressure cycle, foaming machines that are not used for a long time should be usedDOPWait for replacement.
