High pressure grouting pump maintenance

Gaode Equipment Co., ltd. is set research and development and manufacturing for the integration of high-tech joint-stock enterprise, mainly engaged in mining support products, concrete shotcrete machine, injection machine, double liquid grouting machine, high-pressure grouting machine, spray seeding afforestation Equipment research and development production, sales and new building materials sales and consulting services.

High pressure grouting pump maintenance：

(1) Check whether there is any looseness on Tianjin high-pressure pump and piping and junction phenomenon. Turn the pump by hand, and proved the pump is flexible.
(2) To the bearing body join bearing lubrication oil, should observe the oil level in oil mark the centerline, lubricating oil should be timely replacement or supplement.
(3) Unscrewing the pump body of water diversion plug, water perfusion (or plasma).
(4) Close out of the water gate and export of pipeline pressure gauge and imported vacuum gauge.
(5) The motor running, and proved the motor steering is correct.
(6) To start the motor, when the pump running, open the outlet pressure gauge and imported vacuum pump, it shows that the appropriate pressure, gradually open the gate valve, check the motor load condition at the same time.
(7) To control the flow and head of the pump on the signs indicate that the range, so as to guarantee the pump running at peak efficiency, in order to achieve maximum energy saving effect.
(8) Pump in the process of operation, the bearing temperature cannot exceed environment temperature 35 c, the highest temperature should not exceed 80 c.
(9) In case of abnormal sound of a pump should immediately stop check.
(10) To stop the pump when used to close the gate valve, pressure gauge, then stop the motor.
(11) Pump in the first months of work, the oil change 100 hours, every 500 hours later, an oil change at a time.
(12) Often adjust the packing gland, packing materials indoor drip situation is normal (in a drip out as appropriate)
(13) Regularly check the wear condition of shaft sleeve, wear after the larger should be replaced in a timely manner.

(14) During the winter season, when using the parking, the lower part of pump body must be drain plug unscrew put a net to prevent frost crack the medium.
