Whether it is a high pressure cleaning pump or other equipment, before starting to make preparation, nip in the bud, if the equipment in the operation process of emergency have what problem, may cause serious consequences, so the preparation work is very important, so what are the preparations for high pressure cleaning pump before the start, the introduction of Huaian hydraulic diaphragm metering pump manufacturers to everyone.

First, the diesel engine of the high pressure cleaning pump unit

(1): whether the cooling water system of cooling water, antifreeze in line with the requirements of the hose, a connector and a water drain valve is tight, oil coolers, water pumps have no leakage, no leakage, no radiator fan Feixu blocked, the belt tension is appropriate, the fan ring position, there is no foreign body.

(2) fuel oil system: whether there is oil leakage in fuel injector, high-pressure oil pipe, connection and fuel injection pump, whether the injection pump and oil pump operate flexibly and normally, whether the fuel filter is smooth and clean, whether the fuel tank is clean, whether the oil is suitable or not, and whether the oil quantity is sufficient.

(3) the lubricating oil system: lubricating oil, oil is suitable lubricating oil filter is smooth, clean, oil box bottom shell, valve chamber cover, each joint, seal leakage, oil pressure, oil temperature sensor is connected properly and securely, without leakage, connecting wire is off, the circuit breaker.

(4) transmission and clutch: clutch separation, combination is completely in place, clutch operation is flexible, detachable bearing, supporting bearing rotation is flexible, whether there is noise, whether each part gap is suitable, whether to move or beat.

(5) control and instrumentation: whether the instruments and sensors are intact and complete, whether the control cables and distribution cables are intact, neat and standardized, whether the safety chain is intact, sensitive, and whether the instrument instructions are accurate.

(6): power and storage battery is intact and complete, battery fluid density, the liquid level is appropriate, battery cable terminal, is good, clean and strong, the belt tension of the generator is appropriate, the regulator is complete and intact, the total power switch is sensitive and accurate, electricity is enough, whether it meets the requirements of voltage the discharge capacity is enough.

(7) air filter: the filter net of the air filter, the shell is clean, the filter connection pipe is firm and tight.

Second, the auxiliary parts of the high pressure cleaning pump group

(1) lighting fixtures: lamps, pins, sockets, switches are complete and complete, the fixtures are firmly fixed, the arrangement of wires is neat, standard and safe.

(2) door lock latch (closed high pressure cleaning pump group): whether the doors and windows in the workshop are intact, whether the door lock latch is intact, whether the locker lock and handle are intact, whether there is any sign of being turned into turning, and whether there is any dismantling mark on the high-pressure pump group accessories.

(3) special tools: turning tools, start wire, emergency lighting, fire control, torque wrench wrench is complete and intact, neatly placed.

(4) shock absorption connection: whether the cushion iron and the anchor bolt are intact, solid and complete, the position of the high-pressure cleaning pump group has no movement and change.

Third, other preparations for the high pressure cleaning pump unit

(1) check the set of parking place of work high pressure cleaning pump is flat and solid, preferably having a drainage ditch of the cement ground (high pressure cleaning pump group tilt operation, very easy to drift, lubricating oil leakage, caused by the burning of axle tile accident).

(2) the high-pressure pump must strictly carry out manual turning (according to the pump type, not less than 9~15 times), the winter is particularly important.

(3) check the pressure of water supply (not less than 012MPa), flow (according to the pump type pipe diameter should not be less than <32 to 70mm).

(4) check whether the overflow pipe is introduced into the drainage ditch, and it is fixed and stable.

(5) the indication of the power supply of the diesel engine and the high pressure pump and the indicator of the instrument is normal.

(6) the implementation of high pressure pipeline, foot valve, nozzle and so on for cleaning operation.

(7) whether the cleaning workers are ready to be put in place.
