Polyurethane casting machine Liaocheng mold foaming filling

Polyurethane casting machine Liaocheng mold foaming filling

Small polyurethane joint patching machine is mainly used for insulation pouring and filling of buried pipelines. It is recommended to use 1 meter4belowGenerator 50kw

Can also be used forCasting and molding of insulation filling molds for small pipes, straight pipes, and small box sandwich layers

The material pump motor isTwo sets of 4kw and 16ml high-pressure plunger pumps with a single flow rate of 0.3 kg/s

The oil pump motor is3kw， Equipped with a set of pressure maintaining devices

Automatic feeding motor1.5kw， two sets

The weight isA 300kg single material tank is filled with 200kg of loading liquid, and a 1.5kw flange heating tube is installed at the bottom for tank heating

To avoid the stickiness of black materials in winter, pipeline heating was applied to the black materials to improve their flowability and prevent stickiness

Machine operation process:1. Oil pump start 2, material pump start,

When the pouring time is up, the material pump will automatically stop, the injection head will retract, and the oil pump will automatically increase pressure, waiting for the next operation

The injection head is equipped with an external button, which can be operated at the handle after debugging is completed

The dashboard operation is as follows:

1Automatic feeding system

2Heating system

3Pressure holding system (set the upper and lower limits of oil pressure, start the oil pump below the lower limit, stop the oil pump above the upper limit, and stop the oil pump in the middle between the upper and lower limits)

4Time system (lifting time, pouring time, and returning time can be set arbitrarily)

There are two operation buttons: injection start/Stop injection to facilitate on-site construction operations for workers

After the pouring time is reached, the material pump stops running

Equipment time setting: lifting time, pouring time, and returning time

Lifting time: Set the lifting time to ensure that the injection head lifts the rod within the set time. Expose the gap and wait for pouring

Pouring time: Different pouring times are set according to the size of the pipeline. The material pump runs simultaneously and stops at the arrival time

Return time: After the discharge is completed, it is necessary to wait for time to avoid returning the rod immediately, which may cause pressure in the material tank

It is recommended to use a generator with a specification of 50kw and an equipment power consumption of 11kw. The buried pipeline joints should be insulated and poured, with a suitable size of 1.4 meters or less. The recommended mixing flow rate for pouring is 0.5 kilograms per second (to avoid excessive adjustment and inaccurate discharge of viscous materials in winter). The minimum size should be 219 or more,

The size of 219 is too small, the insulation thickness is small, and the pouring amount is small to avoid damaging the motor due to short operation time. It is recommended to use a low flow joint pouring equipment,
