(2) Check the transfer case, inside the turbine oil, add a little required.
(3) Check and tighten the transfer case, drive shaft, large pump mounting screws and connecting the various parts of the screw, without anything close to the drive shaft.
(4) Check the line is smooth, and construction requirements take a good, tight dress.
(5) Check the tightening rod packing, piston, rod, crosshead and cap, where Dole cover screws and the top wire, and Shang Hao various plugs.
(6) View Seoul where insurance and insurance sales installed, having a good cover.
(7) the import and export inspection and construction requirements of booing gate.
(8) Check that the pump suction fluid is clean.
(9) Check the mixer and each line is connected properly; Pup joint, Swivel joint requires a certain range of motion.
(10) If the pump Sheung Shui is inhaled by the pool below, booing Tee gate, if inhaled by tanks, open the valve between the gate and the Tank Tee.
(11) The lubricating grease fittings add a little butter.
(12) will eat into separate partner with pump location.
2. The work of the pump and the pump test after
(1) can be used in this test car tanks pump cycle, from low gear to high gear, look at the situation in Sheung Shui.
(2) according to the construction design requirements, close wellhead gate, hold pressure test conducted low profile, each pipeline junction leakage phenomenon should not have, and that the pump is functioning properly.
(3) under high pressure situations, and the pump pressure Pup joint section shall not stand people, pay attention to safety.
(4) pump working properly, the pressure should be controlled within a range of construction design requirements, or should consult the person in charge of the construction site; but definitely not exceed the rated criteria.
(5) After the pump should always pay attention to the pump pressure transformation, the clutch operation to be smooth, non-clutch semi-linkage.
(6) pump, driver and pump station operations to obtain the contact when the pump stops, reaching harmonization, drivers should obey the command of the pump station.
(7) After the oil pump should loosen fittings on the pump, check the lubricating oil between the crosshead and crank shaft is smooth lines.
(8) the work is prohibited in compliance with the operating condition after discharge fault, must stop the pump discharge pressure, if necessary, further troubleshooting or repair work.
(9) work should pay attention to the transfer case gears and prevent stalls caused by speeding coaster jump.
(10) and pay attention to transmission parts and hydraulic pump part is normal, with or without leakage phenomenon; transmission parts should not have vibration, impact and heat generation, ministries bearing temperature should not exceed 60 ℃.
(11) All operations should be part of freedom of movement; not biased rod mill and packing phenomenon.
3. The pump stops working
(1) should stop the pump at the same time to control the throttle, to prevent speeding.
(2) injection of cement, fight acid, other chemicals squeeze liquid isotope immediately with water circulation pump and various pipeline after a thorough cleaning job.
(3) after stopping the use of a pump problem found, next to the bus ready.
(4) winter work, when the pump stops midway temporary, intermittent cycle should prevent freezing.
(5) winter when the pump stops, open all drain plugs, open each gate, walk 1 to 2 minutes vacuum pump, water pump to drain all piping systems.
(6) remove the pump, tanks, various pipelines, mixers, and funnel knot sand and oil.
(7) When the pump stops long time, remove the rod, piston, cylinder sets, where Seoul and drive some of the parts, cleaning smear butter, proper security custody.
2, Gear Pump rules
1. Open the pump before inspection
(1) Check the part that is good is fixed, the transmission system without any obstacles.
(2) Check the gasoline engine and the gearbox oil, should add a little less, to add a little water pump bearing calcium-based butter. And check petrol tank of the cooling water is adequate.
(3) Check the pump and gearbox coupling section of the chain is good, and coated with oil.
(4) Barring pump 2 to 3 laps, if your deck plate less than a week, you should check to exclude, not numb pump.
(5) winter work, prior to transmission lubricants grilled hot; ice block inside the pump, you must first roast and then work to prevent the gear broke.
(6) Connect the line mixer, open intake gate.
2. pneumatic pump and to work with
(1) the use of the vehicle circulation pump test, first with a block, from low to high, check the mixer nozzle pressure situation, confirmed normal, before beginning work.
(2) work should pay attention to the pressure change and the gasoline engine operating conditions.
(3) pay attention to the work of the mixed slurry specific gravity and viscosity, according to the construction design requirements, choose the appropriate gear and throttle control, and operating carts, custody funnel comrades closely.
(4) work to be stopped midway when the pump must be replaced neutral and close intake gate, preventing dilute slurry mix to ensure construction quality.
(5) work around the pipeline may not have leakage phenomenon.
3. The pump stops working
(1) Stop the pump intake should be first off the door, if the grout, mud or oil liquid material should be cleaned immediately.
(2) stop the pump motor should be checked before each transmission some cases, when a failure occurs after the pump stops to eliminate them.
(3) exclude the mixer after the pump stops, the funnel and piping system fluid, open the pump at the bottom of an empty pump plugs run 1 to 2 minutes, drain the water before the pump stops.
(4) Elimination of the pump in the work of the view out of the failure.
(5) Check and add pump packing and lubricants.
3, plunger displacement pump procedures
1. Open the pump before inspection
(1) Check and tighten the screws on the ministries pipes connecting screws.
(2) Check and add a little gearbox, chain, crank and connecting rod bearings, skateboards, etc. throughout the plunger lubricants, before the oil pump must be filled cup.
(3) check, for out of the water where the rubber Seoul, where Seoul and tighten cover screws.
(4) Check the chain pin and the pin is fully insured, and be lubricated.
(5) Check pump pressure gauge connected to the mixer Sheung Shui pipeline and pipeline connections.
(6) intake door open to ensure good flexible.
2. Test the pump and work
First with a block (1) test the pump, close the smooth clutch, throttle on the lowest position, pay attention to the pump pressure and Sheung Shui, the confident start work before the normal cycle.
(2) according to the construction work required to select gears.
(3) the operation and constant attention to the work of the pump.
3. Stop the pump
(1) Stop the pump should be promptly transferred to the engine throttle at low speed, slowly stop the pump.
(2) should be excluded after the pump stops pumping water, especially in winter, to be open all drain plugs, air pump 1 to 2 minutes, the water drained.
(3) Elimination of the pump at work to check out the failures.
(4) Check the rubber out of the water where Seoul and Seoul where cover gaskets, replace if necessary.
(5) around the filling oil, tighten all bolts and thoroughly cleaning equipment appearance.
