Abstract
The utility model discloses a plunger pump oil seal replacing tool used in oil industry which is applicable in adding and replacing a center-pole oil seal of the plunger pump of a water input well. The utility model comprises a waste material barrel, a loading or unloading sleeve, a pad, a center-pole and a screw nut, wherein the waste material barrel, an oil seal box whose oil seal needs replacing, the loading or unloading sleeve and the pad are sequentially sheathed on the center-pole, and the screw nut is installed on the top end of the enter-pole. The current problems which are that oil is leaked from the oil seal, the oil seal and the oil seal box is damaged, the efficiency of starting pump is low and the work intensity of the operator is high without special tools are settled down by the utility model. The operation is simple, the replacing is convenient, thereby the work efficiency is improved and the oil seal replacing of the plunger pump which is originally difficult is simply implemented.
Description
Technical field
The utility model belongs to the maintenance tool of petroleum industry water injection equipment, and plunger displacement pump oil seal replacement instrument particularly is used for adding of water injection well plunger displacement pump center pull rod oil sealing to get and change.
Background technology
In petroleum industry, water injection well generally uses the high-pressure plunger pump priming, and the sealing of plunger displacement pump center pull rod is the main seal of equipment lubrication.Present center pull rod is sealed into O type rubber framework grease seal, and O type rubber framework grease seal cooperates closely with the oil sealing box, after oil sealing damages, does not have specific purpose tool to add and gets or change.Can only oil sealing be prized from the oil sealing box with screwdriver, also can only new oil sealing be pounded into the oil sealing box during installation with screwdriver.Installing and taking off oil sealing wastes time and energy, and the serviceability rate that oil sealing is installed is low, spoilage is high.Use back lubricating oil leakage amount height, shortened service life of equipment simultaneously.The frequent sealing oil sealing of changing has strengthened the post operation personnel labor intensity, and life cycle is short, rate when having influenced turn on pump.For a change this situation, the scene needs a kind of high-pressure plunger pump oil sealing installing/dismounting device.
Summary of the invention
The purpose of this utility model provides plunger displacement pump oil seal replacement instrument, guarantees that the installation site of oil sealing is accurate, improves the serviceability rate that oil sealing is installed, and makes it simple to operate, reduces labor intensity of operating staff.
Following technical solution can reach above-mentioned purpose: plunger displacement pump oil seal replacement instrument comprises waste material tube, loading and unloading cover, pad, center-pole and nut, waste material tube, the oil sealing box that needs to change oil sealing, loading and unloading cover and pad are sleeved on the center-pole in proper order, nut is installed on the center-pole top.
The utlity model has following beneficial effect: solved at present owing to the oil sealing leakage of oil that does not have specific purpose tool that oil sealing is installed to cause, damage oil sealing and oil sealing box problem such as the low and post operation personnel labor intensity height of rate during turn on pump.This apparatus structure is simple, low cost of manufacture.Because simple to operate, it is convenient to change, and has improved operating efficiency, can make the comparatively difficult originally oil seal replacement work of plunger displacement pump become simple.When having reduced labor strength, rate when having improved turn on pump has reduced the machine oil loss, has prolonged the service life of equipment, has reduced production cost.
Description of drawings
Accompanying drawing is structure of the present utility model and use schematic diagram.
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to accompanying drawing, plunger displacement pump oil seal replacement instrument comprises waste material tube 2, loading and unloading cover 3, pad 4, center-pole 5 and nut 6, waste material tube 2, the oil sealing box 1 that needs to change oil sealing, loading and unloading cover 3 and pad 4 orders are sleeved on the center-pole 5, nut 6 is installed on center-pole 5 tops.Loading and unloading cover 3 one end external diameters are big, other end external diameter is little, and the middle part internal diameter is provided with partition, and its partition is provided with centre bore; The big end of loading and unloading cover 3 external diameters, the internal diameter of its external diameter and oil sealing box oil sealing chamber 1 coincide, and the end that loading and unloading cover 3 external diameters are little and the internal diameter of oil sealing box 1 installing hole coincide, so design, be convenient to new oil sealing is pushed oil sealing box 1, also be convenient to waste and old oil sealing is released from oil sealing box 1.The bottom of center-pole 5 is designed block or is installed and fixed nut.The tube end of waste material tube 2, be provided with centre bore, its top cylindrical shell external diameter equates with oil sealing box 1 external diameter, the internal diameter of waste material tube 2 is a bit larger tham the internal diameter of oil sealing box oil sealing chamber 1, and the end face seat of being convenient to oil sealing box 1 when dress is got oil sealing and makes waste and old oil sealing enter waste material tube 2 on waste material tube 2.
For convenience on the center pull rod of plunger displacement pump, take off the oil sealing box 1 that old oil sealing is housed smoothly, can be with the several L shaped grooves of design on the oil sealing box 1 installing hole external diameter periphery, cooperate this instrument waste material tube 2 to use, at the several internal thread holes of waste material tube 2 relative set, installation small screw 7 hangs over the L shaped groove the inside on oil sealing box 1 external diameter, and oil sealing box 1 is taken off from the pump housing smoothly.
The scene of this instrument is used as be following: the oil sealing box 1 that old oil sealing at first will be housed from the Plunger pump body takes off.Unload old oil sealing: waste material tube 2 is enclosed within on the center-pole 5, the oil sealing chamber of oil sealing box 1 and waste material tube 2 is aligned be inserted in center-pole 5, the installing hole of the smaller diameter end of loading and unloading cover 3 and oil sealing box 1 is aligned be inserted in center-pole 5, suit pad 4 on it is screwed into nut 6.Rotating nut 6 promotes loading and unloading cover 3 and moves down, and the old oil sealing in the oil sealing box 1 is pushed in the waste material tube 2, finishes the dismounting of old oil sealing.New oil sealing is installed: the installation procedure of this instrument is identical with dismounting, only needs oil sealing box 1 and loading and unloading cover 3 are installed conversely, and the larger diameter end of loading and unloading cover 3 and the oil sealing chamber of oil sealing box 1 are aligned, and installs new oil sealing additional between oil sealing box 1 and loading and unloading cover 3.Same rotating nut 6 moves down loading and unloading cover 3, and new oil sealing is pushed in the oil sealing box 1, finishes the installation of new oil sealing.The manufacturing of this instrument is simple, and is easy to operate, can effectively protect oil sealing box 1 and new oil sealing, thereby reduce oil consumption, reduces production costs.
