purpose < /span>
Pumping Controlled Credular K80-50 -200th and electrical units on its basis are designed for pumping oil products to 10 -4 <-4 < /span> m 2 /s (100 SST), with a temperature of 253 to to 358k (from minus 20 ° C to plus 85 ° C), with a solid inclusion content of not more than 0.2% and a size of not more than a size 0.2 mm.
Pumps that are part of the unit , belong to general purposes, type I (restored) according to GOST 27.003-90 and are produced in climatic design U3.1 (from minus 10 ° C to plus 40 ° C) and T2 (from minus 10 ° C to plus 50 ° C) According to GOST15150-69.
Pumps (units) comply with the requirements TR TS 010/2011, TR TS 012/2011 and Designed for installation in explosive and fire hazardous rooms. Explosion-proof equipment- group II, explosion protection level GB- “High”, temperature class- T4 (135 ° C) according to GOST 30852.0-2002 and GOST30852.5-2002, type of explosion protection “C”- protection of structural safety according to GOST 31441.1- 2011, GOST 31441.5-2011 and GOST 31438.1-2011.
Pumps of K-e (units) are allowed to work in explosive rooms of category IIA, IIV and explosion hazard groups T1, T3, T3 According to GOST 30852.19-2002. Classes of explosive zones 1, 2 GOST 30852.9-2002 and class B-1A according to PUE (seventh edition).
Design
K80-50-200 pump-centrifugal, horizontal, console consists of a case, a working wheel, diaphragm (density building ), bracket, shaft with bearings. To seal the leaks on the pump shaft, depending on the working conditions and the requirements of the customer a end of or single with auxiliary ).
The pump case represents a steel casting, In which the input and output pipes, a spiral camera and supporting paws are made. The entrance to the pump is located along the rotation axis, the output pipe is directed vertically upward and is located in the same plane with the wheel axis. A flange of a cast iron bracket is attached to the pump body, in the bore of which the ball -bearing supports of the shaft are installed. To measure the temperature of the bearings in the bracket, two holes M8X1-7N are provided. Recommended Temperature Devices DTS034-RT100. In3-20/4.5-T4 TU4211-023-45626536-2009.
In the Bath of the Kronstein, a threaded hole is provided M12x1.5-7n for connecting a bolt or pumped liquid leakage system by the customer at the operation site. The leakage is removed by the customer in the drainage or in special containers. The lids fixing the bearings are made of bronze to exclude sparking.
Steel is located between the case and the bracket. A diaphragm or steel seal case, in which double end seals or a single end seal with auxiliary cuff are installed. In the steel body of the seal, two holes M12x1.5-7n are located for the supply and removal of the bolt fluid to the double end seal, which also serves for cooling or heating the seal. The washing of a single end seal with an auxiliary cuff is provided structurally pumped with liquid, through the inner hole in the sealing case. A hole is made in the sealing case, which can be used to connect an electrocontact pressure gauge (ECM). To increase the resource of the cuff, it is recommended to fill the cavity between the main seal and the auxiliary cuff with lubricant Litol-24 GOST 21150-87 (0.03 kg). When connecting EKM and stable sealing (without exceeding the maximum permissible concentration), leaks pass along the shaft along the cuff and are taken to the collection. In case of failure of the main seal, the pressure in the cavity between the main seal and the cuff rises and the EK gives a signal to turn off the pump unit.
The centrifugal operating wheel is a casting from bronze. The wheel is mounted on the shaft with a vene and a fairing. The wheel is unloaded from the action of the axial force. The shaft of the pump and engine is connected by an elastic overwhelming-band coupling closed with a protective casing with a final circuit breaker. The protective casing provides a guaranteed gap between the coupling and the casing. The switch ensures the operation of the unit only with a closed casing. The direction of rotation of the shaft is clockwise if you look from the drive side.
There is a pump in the upper part of the pump body The hole M12x1.5-7n, closed by a traffic jam, for the release of air, in the lower part of the case - for draining the remains of the liquid.
A bolt for the building is installed for the paw of the building Providing the grounding device.
The unit in general and all the components Its equipment (engine, frequency converter, measuring instruments, etc.) should be used in explosion-proof execution and have certificates for compliance with the requirements of TR TS 012/2011, GOST30852.0-2002, GOST 31441.1-2011, GOST 31441.5-2011, GOST, GOST, GOST 31438.1-2011. The electric motor, pump and other components of the unit should have an explosion protection level corresponding to the explosiveness class of the equipment installation zone. The overall level of explosion protection of the unit (equipment) should be determined by the complete element, which has the lowest level of explosion protection.
