Abstract
The utility model relates to a pump hydraulic packing, in particular to a leak-free packing at the hydraulic end of a PG pump, which is composed of a sealing gland and a pump head plunger, wherein a supporting ring, a self-lubricating first ring, a pressure main ring, an isolating ring, a copper isolating ring, a guide ring and a sealing ring are disposed in the sealing gland, and the isolating ring is separated from the self-lubricating first ring by the pressure main ring. The pressure main ring is composed of a copper oil ring, a filter ring and a nylon cushion rubber gasket, when the packing is used, all the rings are coated on the pump head plunger, thereby achieving the purposes of wear resistance, pressure resistance, good sealing property, saving lubricating oil without oil leakage or polluting environments.
Description
Technical field:
The utility model relates to pump fluid power packing, and especially the PG pump hydraulic end does not have the leakage packing.
Background technique:
At present, the JSJ35-15 cementing truck PG pump hydraulic end packing during oil well cementing, a kind of oil bath type packing of forming by rubber cushion, copper ring, oil ring, in the use sealing poor, leak lubricant oil easily, and can't reclaim, cause environmental pollution, the life cycle weak point influences cementing operation.
The model utility content:
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and the PG pump hydraulic end that provides does not have the leakage packing.Increased the wear-resisting and compressive strength of packing, oil leak was few when packing_seal used well.
The technological scheme that its technical problem that solves the utility model adopts:
Be the task of realizing the utility model proposes, it is made up of sealing gland, pump head plunger; Support ring, the first ring of selflubricating, pressure main ring, isolating ring, copper isolating ring, guide ring, seal ring are equipped with in described sealing gland the inside, separate by the pressure main ring between first ring of selflubricating and the isolating ring.Described pressure main ring is to be made of copper oil ring, sphere filter, nylon pad cushion rubber, copper washer; O RunddichtringO and oil sealing are housed in seal ring, during use, get final product above this packing is installed in cement pump truck pump head plunger.
The more former packing_seal performance of this packing is good, has enlarged pump truck medium Applicable scope, therefore applicable to the every operation of acidifying, pressure break and sand control, and can use in subzero 45 ℃~149 ℃ of operating mode scopes above freezing.
Description of drawings:
Accompanying drawing is the utility model mounting structure schematic representation.
Among the figure by 1, support ring, 2, the first ring of selflubricating, 3, the pressure main ring, 4, isolating ring, 5, the copper isolating ring, 6, guide ring, 7, the O RunddichtringO, 8, seal ring, 9, oil sealing, 10, sealing gland, 11, the pump head plunger forms.
Embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing
During installation with the above-mentioned gland that respectively encircles on cementing truck pump head plunger, separate by pressure main ring 3 between first ring 2 of selflubricating and the isolating ring 4 and get final product.
Described pressure main ring 3 is to be made of copper oil ring, sphere filter, nylon washer, copper washer, have in " O " RunddichtringO 7 and the oil sealing 9 pressure main rings to be made of copper oil ring, sphere filter and nylon cushion rubber, copper washer in seal ring 8, this packing can use in subzero 45~149 degree scopes above freezing.
